Tabata Trash Mapping: Data for Solid Waste Management in Informal Settlements

Tabata Trash Mapping: Data for Solid Waste Management in Informal Settlements

Piloting solid management system on informal settlements by creating data sets for trash collection companies to help them in locating and track their clients

Dar es Salaam is one of the fastest growing cities in Africa. The population is expected to grow so much, that Dar es Salaam is projected to be the second largest city by population in the world by 2100, with a predicted population of 76 million, (according to World Population Review). The annual growth rate is expected to average 4.39% through the year 2020. In the next three years the population is expected to reach 5 million.

With this rate of rapid urbanization and population increase with 70% of its people living in informal settlements, waste management (solid waste in particular) is a serious problem. Concurrent with recent socio economic development, the quantity of solid waste generated has increased at a rapid rate. There have been policies and laws to guide solid waste management in Dar es Salaam but it has never been effective, such that people tend to dump solid waste any way they can as there is no proper and effective way of waste collection

Flooding in Dar es Salaam is mainly caused by blockage of the waterways, i.e. rivers, drains, streams, ditches, etc. People dump solid waste and cause such blockages. Materials like metal, plastics, and sometimes natural debris are being dumped causing flooding. Without proper and effective ways of managing waste, floods will continue to overwhelm the drainage system, overflowing into communities, In Tabata most houses are flooded due to blocked drains.

HOT, with their local partner OMDTZ and supported by the World Bank, decided to pilot a mapping activity in an informal settlement (Tabata Ward) similar to what they have done in formal areas (Mchafukoge and Kisutu wards) and create datasets that may help trash company collectors to effectively collect trash from their clients.

HOT and OMDTZ partnered with Joshemi Company Limited, a company  dealing with trash collection in Tabata. Tabata is an administrative ward in the Ilala District. According to the 2002 census, the ward had a total population of 46,228. The ward is comprised of eight subwards [Mandela, Kisiwani, Tenge, Msimbazi Mama, Msimbazi Magharibi, Tabata, Matumbi and Mtambani]. It is mainly comprised of informal settlements and is found along the Msimbazi River valley (the main flooding river in the city).

Joshemi Company has created a weekly schedule for every subward where they have to collect the solid waste. Residents and owners of business firms must pay a certain amount to the company depending on the size of the trash bag.

The Aim of Mapping

JCL needed to know the number of clients as it was very difficult to track them all, revenue flow and an effective feedback system on services provided by the company. The aim was shifting JCL’s analogue system of trash collection to a digital system by providing them with their own maps of clients’ locations and a system of tracking them. This way, JCL would improve their services to clients, increase their revenues and create an effective waste collection mechanism.


Pilot mapping was conducted in two subwards of Tabata Ward (Msimbazi Magharibi and Msimbazi Mama). As our policy has always relied on open source software, we used OpenDataKit (ODK) Collect and OpenMapKit (OMK) – an extension of ODK which is a free and open android application for data collection. The team worked with revenue collectors to conduct mapping as they have a better understanding of the area to ease the process of data collection.

The team prepared an excel sheet with ward, subward name, the name of mjumbe, location together with client information including name, phone number, month, amount and receipt ID. To ease the process, fake ID numbers were created to identify clients’ houses because in informal settlements there are no house numbers. The sheet was then printed and given to the mappers for data collection, data cleaningand processing.

Outcomes and Impact

The company has a full understanding of the location and number of clients and challenges that their clients face. As the company now knows the number of clients, they plan to improve their services by having more trucks and more trips. Before mapping, they were only serving 300 clients, and after mapping, they have come to a realization that there are 2000 clients that need to be provided with the service. This will not only increase the company’s revenue but also improve service to the citizens and keep the ward clean.

Johanes Petro, a mapping supervisor at OMDTZ is very positive about the initiative. He said,

“This initiative will lead to improved waste management as the company now knows they have many clients, they may double or triple services and the clients will be serviced accordingly. In turn, this will increase revenue to the company and improve services to citizens”. He added, “There is a need to replicate this process to all informal settlements in Dar es Salaam which will contribute to a sustainable and clean city as the system created is user friendly”

Note: Until now, our team is working with the revenue collectors to capacitate them on data use and help to establish the link between the excel sheet prepared and established layers of OMK.

Challenges in Data Collection

The team started the process of data collection with the revenue collectors, but the revenue collectors were a bit hesitant to provide full collaboration as they were fraudsters and printing counterfeit receipts. So they believed if the company is provided with reliable data and the exact number of clients under service, their stealing methods would be revealed. So they did not collaborate and the company fired them.

Mappers had to shift from working with revenue collectors to shina leaders, famously known as “wajumbe” – the hyper local leaders (the most granular level of administration that exists in Tanzania). These leaders are responsible to administer a small cluster of houses ranging from 50 to 200 houses, and they are citizens’ primary point of contact. So working with them is an advantage as they are well known and trusted by the community

What is Next?

Seeing the positive outcomes on the two pilot subwards, there is a need to extend the project to the remaining six subwards of Tabata and even to the whole city if we had the support and funding from different partners. Joshemi Company that we’re working with are also eagerly waiting for the extension to the remaining subwards as they understand the power of data now- they even decided to pay community leaders and wajumbe that were helping mappers on data collection.

If this process is replicated in the remaining wards of the city, trash collection will be easier, the city will be clean and may also reduce the intensity of flooding as it is normally caused by blocked drains and rivers. There is also a need to develop an integrated solid management system which is cost effective and that takes into account economic options for solid waste management like recycling. The community and the general public also need to take responsibility on the process by collaborating with waste collection companies because the benefits are reciprocal. Our mappers are working on solidifying relationships between clients and companies as there was observed drift among them.

Hyperlocal Boundary Mapping

After the risk identification process implemented in 228 subwards of the city, Ramani Huria is now going further to map the lowest level of administrative system that exists in Tanzania. To do this we have partnered up with Data Zetu to map hyperlocal boundaries in Dar es Salaam for better decision making. Finding people with exact addresses is nearly impossible, as most part of the city is unplanned. Therefore, mapping Dar es Salaam to such a detailed level will allow us to address issues at a neighborhood level for the first time. This is very important and will be used in different levels for decision making from individuals to the government.

Dar es Salaam is divided into 5 municipalities, 92 wards, and approximately 452 subwards (a subward is also known as a “mtaa” in Swahili). Within an mtaa there are further divisions known as “shinas” (which translates roughly to “branches” in English). Shinas are sometimes also referred to as a “Ten Cell”, since originally these areas were home to ten households. Now, due to increases in population, it tends to be between 30 and 200 households per shina. Each shina is administered by a ‘mjumbe’ (plural ‘wajumbe’ in Swahili).

Shinas were originally a political construct, related to the organization of specific political parties. However, wajumbe are increasingly functioning as non-partisan public servants, often the first (and in some cases only) point of interaction between citizens and government. Though the political character of shinas has not entirely vanished, we are finding increasing acceptance amongst citizens and leaders (of all political stripes) of the utility of hyperlocal boundaries being mapped and known to all.

Ramani Huria and Data Zetu have aimed to conduct hyperlocal mapping within 84 subwards of Dar es  Salaam. From 13th September to now 128 hyperlocal boundary data have been collected and 106 have been cleaned and verified for final map production.

  • A student will need a smartphone/Android phone installed with a revised version of Open Data Kit (ODK) which allows tracing lines/polygons easily.
  • Mjumbe, who is a shina leader, works with a student (mapper) to trace the boundary of his/her shina – also explaining the possible uses of shinas to enhance collaboration and participation. A student mapper with mjumbe will walk around the boundary creating a polygon-like structure then fill the right information on the survey such as number of shina, name of shina mjumbe and others.
  • After tracing the shina boundary, mjumbe and mapper use the the printed aerial imagery as a field paper to compare what has been traced from the field with the image to make sure they have traced the correct boundary.
  • Then students will send a form/survey to the server for further processes.
  • Data will be downloaded from the server which will be digitized through QGIS software, analysed and a hyperlocal boundary map produced.

Community Insights

Community leaders had their opinions on the process of mapping shinas and they are expecting these data will be used to benefit them as a community, which is actually the goal of collecting them. Subward chairperson had some thoughts:

“With shina mapping it will help us to solve different problems in our communities since people will be clear with the administrative boundaries of their local leaders. Am happy to work with this organization and hopefully my representatives have fully participated and they are also happy for the work that your doing.” Abdallah M. Simbili, Chairperson Liwiti Subward.

Possible uses of Hyperlocal Maps

  1. Help the ward officers to manage the areas by allowing the ward/subward/shina leaders to better understand the structure of their areas.
  2. In case of emergencies (e.g. fire outbreaks or flooding), shina maps can be of help in responding to these disasters as the location of the target is known.
  3. In hospitals, tracking people’s origin by identifying their shina number at the registry- this will help to track patients with diseases like cholera, or malnutrition in children.
  4. Shinas help the local people to know their representatives on the subward level since most of local problems are solved from the shina level.

Locating Malnourished Children and Help with Intervention

Malnutrition remains  one of Tanzania’s greatest  human development challenges. Despite  displaying seemingly ‘low’ and ‘acceptable’ rates of acute malnutrition, the burden of undernourished children is one of the highest in the East African Region. An estimated 450,000 children in Tanzania are acutely malnourished or weak, with over 100,000 suffering from the most severe form of acute malnutrition.

With one of the highest burdens of under nutrition in East and Southern Africa, it is not solely individual lives in Tanzania that are threatened, but also the economic advancement of the next generation that is at stake. Individuals – both adults and children – who experience varying levels of malnutrition will struggle to take advantage of opportunities in, for example, education and employment that would enable them to improve their livelihoods. Understanding the devastating impacts associated with societal malnourishment, particularly amongst children, it is absolutely crucial that appropriate measures are put in place by those actors who are in a position to do so to mitigate such consequences.

Case Study: Amana Regional Referral Hospital in Dar es Salaam, Tanzania

Through the Data Zetu program, our team has been able to utilize the shina data collected across 36  subwards to support the Amana Hospital – one of 4 referral hospitals in Dar es Salaam serving between 800 and 1200 people each day – in improving their methods for collecting patient location data and enhancing patient origin tracing. One pediatric doctor at Amana Hospital, Dr. Omari Mahiza, has a keen interest in implementing a system that would enable him to record and track the location of the malnourished children he treats. By knowing more precisely where his patients are coming from, he is able to investigate why and the reasons for children’s malnutrition from one community to another and, in turn, uncover in more detail the causes that lead to this condition from one household to another.

For the past few months, the Data Zetu team has been working with the IT company who built the electronic medical record system at Amana Hospital to incorporate shina data and nearby landmarks into the system. The new fields in the e-health registry will enable staff to record more precise location data of patients who visit the hospital and support Dr. Mahiza and his colleagues in being able to pinpoint the home address of their patients more easily. Whether the motive is to investigate specific cases of malnutrition and the habits that lead to this condition or to locate the source of a seasonal outbreak, such as cholera, within a community, shina maps allow for this to happen more efficiently within a given community.

The next step for the Amana Hospital intervention is to provide training and capacity-building to local staff, such as registration attendants and nurses, about the importance and value of recording detailed patient location data in the e-registry. To ensure there is genuine understanding and interest among staff to record patient location data more systematically, our team will focus on facilitating discussions and highlighting use cases that exemplify the role that maps and other spatial tools play in strengthening public health in communities.

Beyond health interventions Shina maps can also be used in disaster management, facilitating disaster response as well as increasing the overall flood resilience of communities. For example, having more granular level administrative boundaries can increase precision in identifying affected areas and speed up the distribution of relief resources during and immediately after a flood event.  Likewise having maps of shina boundaries may also prove useful to local administrators when directing and implementing infrastructural improvements.


Utengenezaji wa ramani za mipaka ya shina.

Baada ya mchakato wa kutambua maeneo yaliyo kwenye hatari kwenye mitaa 228 ya jiji la Dar es Salaam, Mradi wa Ramani Huria unaenda mbali zaidi na kutengeneza ramani za maeneo ya chini kabisa ya utawala yaliyopo Tanzania (shina). tunafanya hivi kwa kushirikiana na mradi wa Data Zetu  kusaidia katika kufanya maamuzi. Kujua anwani za watu wanapoishi ni ngumu sana kwenye mji ambao haujapangwa. Hivyo kutengeneza ramani hizi kutasaidia kutatua matatizo mengi ya ramani kwa mara ya kwanza. Suala hili ni la muhimu sana na litatumika katika maamuzi kuanzia watu binafsi hadi ngazi ya serikali.

Dar es salaam imegawanyika katika manispaa tano, kata 92 na takribani mitaa 452. Ndani ya mtaa kuna mgawanyiko mwingine unaoitwa shina. Mashina pia hufahamika kama nyumba kumi, kwa kuwa mwanzoni mashina yalikuwa na nyumba kumii tu. Lakini kwa sasa kutokana na ongezeko la watu mijini mashina haya yana nyumba kuanzia 30 hadi 200. Kila shina huongozwa na mjumbe au balozi kwa vijijini.

Shina mwanzoni yalikuwa kisiasa,kulingana na mwongozo wa chama fulani. Hata hivyo wajumbe kwa sasawana kazi nyingi tofauti na za chama, kwanza ndio watu wa kwanza wanaounganisha wananchi na serikali. Japo suala la kisiasa katika shina halijapotea, ila tunaona wanaendelea kukubalika na wanajamii ana viongozi wa vyama vyote na matumizi ya mipaka hii ya shina kutengenezewa ramani na kufahamika kwa kila mmja.

Ramani Huria na Data zetu inalenga kutengeneza ramani hizi kwenye mitaa 84 ya Dar es salaam.  Tangu tarehe 13 septemba hadi sasa data za mashina 106 zimekusanywa na kuchakatwa kwa ajili ya utengenezaji wa ramani.

 Msimamizi wa utengenezaji wa ramani akitoa mafunzo kwa wanafunzi wa vyuo vikuu jinsi ya kukusanya mipaka na kuonyesha ramani ya mashina iliyokwisha japishwa; Picha- Ramani Huria.

Mbinu za Utengenezaji wa Ramani hizi.

  • Mwanafunzi atahitaji simu ya mkononi (Android) iliyowekwa programu ya ODK yenye marekebisho ambayo ina uwezo wa kuchukua taarifa za mistari kwa urahisi
  • Mjumbe, ambaye ni kiongozi wa shina atafanya kazi na mwanafunzi (aliyepata mafunzo) ili kupata mipaka ya shina- wakati huohuo mwanafunzi huyo atamueleza mjumbe juu ya matuizi mbalimbali ya ramani itakayo tengenezwa ili kuongeza ari ya usiriki. Mwanafunzi na mjumbe watazunguka katika mpaka wa shina na kujaza taarifa zote zinazotakiwa kama namba ya shina, jina la mjumbe nk.
  • Baada ya hatua hii, mjumbe pamoja na mwanafunzi watatumia picha ya anga iliyochapishwa ili kuhakikisha taarifa ya mipaka waliyokusanya kama ipo sahihi.
  • Mwanafunzi atatuma fomu/dodoso kwenye seva kwa ajili ya michakato mingine.
  • Taarifa hizo zitapakuliwa (download) kutoka kwenye seva ambazo zitafanyiwa kazi kwa kutumia programu ya QGIS, na kuchambuliwa ili kutengeneza ramani hizo za shina

Ufahamu wa Jamii.

Wanajamii walikuwa na mawazo tofauti tofauti kuhusu mchakato huu na wana matarajio makubwa kuwa data hizi zitatumika kwa ajili ya jamii husika, na hili ndilo lengo. Mwenywkiti wa mtaa wa Liwiti alikuwa na haya ya kusema:

“Ramani za mashina zitasaidia kutatua matatizo mbalimbali kwa kuwa watu watafahamu vizuri mipaka yao. Nina furaha kubwa kufanya kazi na shirika hili na ni matumaini yangu wawakilishi wangu amewapa ushirikiano mkubwa, na wamefurahi kufanya kazi nanyie” Abdallah M. Simbili, mwenyekiti wa mtaa- Liwiti

Matumizi ya Ramani Hizi.

  • Itawasaidia watendaji wa mitaa kuelewa vizuri maeneo wanayo ongoza.
  • Kipindi cha dharura (kama moto au mafuriko), ramani hizi zinaweza kutuikaa kutoa misaada ya haraka kwa kuwa eneo halisi la tukio linafahamika.
  • Kwenye hospital, kujua watu wanapotoka kwa kujua namba za mashina katika programu ya usajili kuweza kujua ueneaji wa magonjwa kama kipindupindu na utapiamlo kwa watoto.
  • Kusaidia jamii kujua wawakilishi wao katika jamii kwa kuwa migogoro mingi hutatuliwa na viongozi hawa.

Kufahamu Maeneo ya Watoto wenye Utapia mlo na Kusaidia kwenye Harakati

Utapiamlo bado ni mojawapo ya changamoto kubwa za maendeleo ya binadamu Tanzania. Licha ya kuonekana/kusadikika viwango vya “chini” na vya “kukubalika” vya utapiamlo mkubwa, mzigo wa watoto wasio na chakula ni mkubwa Afrika Mashariki. Inakadiriwa watoto 450,000 nchini Tanzania wamepungukiwa na hawana nguvu, wakati zaidi ya watoto 100,000 huteseka kutokana na aina kali zaidi ya utapiamlo mkubwa.

Pamoja na mzigo mkubwa wa lishe Afrika Mashariki na Kusini mwa Afrika, sio tu maisha ya mtu binafsi nchini Tanzania ambayo yanatishiwa, lakini pia maendeleo ya kiuchumi ya kizazi kijacho yanahusika. Watu – wote wazima na watoto – ambao wana uzoefu wenye uzoefu tofauti tofauti wa janga la utapiamlo wajitahidi kutumia fursa, kwa mfano, elimu na ajira ambayo itawawezesha kuboresha maisha yao. Kuelewa athari mbaya zinazohusiana upungufu wa chakula, hususani miongoni mwa watoto, ni muhimu sana na hatua zinazofaa zichukuliwe na watendaji ambao wana uwezo wa kufanya hivyo ili kupunguza madhara hayo.

Eneo la mfano; Hospitali ya Rufaa- Amana Dar es Salaam, Tanzania

Kupitia mradi wa takwimu za Data Zetu, timu yetu imeweza kutumia data ya mipaka ya shina iliyokusanywa kwenye mitaa36 ili kuunga mkono Hospitali ya Amana – moja kato ya hospitali nne za rufaa Dar es Salaam zinazohudumia watu kati ya 800 na 1200 kila siku – katika kuboresha njia zao za kukusanya data ya eneo la mgonjwa na kuimarisha ufuatiliaji wa taarifa za mgonjwa anapotoka. Daktari mmoja wa watoto katika Hospitali ya Amana, Dk. Omari Mahiza, ana hamu kubwa ya kutekeleza mfumo ambao utamwezesha kurekodi na kufuatilia maeneo wanayotoka watoto wenye utapiamlo anaowatibu. Kwa kujua zaidi ambapo wagonjwa wake wanatoka, anaweza kuchunguza kwa nini na sababu za utapiamlo wa watoto kutoka kwenye jamii moja hadi nyingine na, kwa upande mwingine, kujua kwa undani sababu zinazosababisha hali hii kutoka kaya moja hadi nyingine.

Kwa miezi michache iliyopita, timu ya Data Zetu imekuwa ikifanya kazi na kampuni ya IT ambayo imejenga mfumo wa kurekodi wagonjwa kwa njia ya kielektroniki katika Hospitali ya Amana ili kuingiza data ya shina na alama muhimu zinazotambulisha eneo (landmarks) kwenye mfumo huo. Sehemu mpya itakayoongezwa katika programu hiyo ya usajili wa kielektriniki utawawezesha wafanyakazi kurekodi data sahihi ya eneo la wagonjwa ambao wamefika hospitalini na kumsaidia Dk. Mahiza na wenzake kuwa na uwezo wa kubainisha anwani ya wagonjwa wao kwa urahisi. Ikiwa lengo ni kuchunguza matukio maalum ya utapiamlo na tabia zinazosababisha hali hii au kupata chanzo cha kuzuka kwa magonjwa ya msimu, kama vile kipindupindu, ramani za shina zitawezesha hili lifanyike kwa ufanisi zaidi katika jamii husika.

Hatua inayofuata kwa Hospitali ya Amana ni kutoa mafunzo na kujenga uwezo kwa wafanyakazi wa ndani, kama wahudumu wa usajili na wauguzi, kuhusu umuhimu na thamani ya kurekodi data ya eneo  anapotoka mgonjwa wakati wa usajili. Ili kuhakikisha kuna uelewa wa kweli na maslahi kwa wafanyakazi wa kurekodi data ya eneo wanapotoka kwa ufanisi zaidi, timu yetu itazingatia kuwezesha majadiliano na kuonyesha matumizi ya ramani kwa kuonyesha mifano dhahiri ya jinsi gani taarifa hizi zinaweza kuimarisha huduma za afya kwa jamii.

Zaidi ya mipango ya afya, ramani pia zinaweza kutumika katika usimamizi wa maafa, kuwezesha mipango ya haraka ya kukabiliana na maafa na kuongeza ustawi katika kupambana na mafuriko kwa jamii. Kwa mfano, kuwa na mipaka ya utawala katika ngazi ya chini zaidi inaweza kuongeza usahihi katika kutambua maeneo yaliyoathirika na kuharakisha usambazaji wa misaada wakati na baada mafuriko. Vivyo hivyo kuwa na ramani za mipaka ya shina inaweza kuwa na manufaa kwa watendaji wa mitaa wakati wa kuongoza na kutekeleza maboresho ya miundombinu.

Community meetings- For Flood resilience plan.

[:en]*Written by Hawa Adinani and Amelia Hunt*

The meeting was conducted in two sub wards of Kigogo ward with participatory community discussions to see how community driven information can help to develop this plan.

On the 26th and 27th of March 2018 the HOT Tanzania team conducted a pilot community meeting in Mbuyuni subward in Kigogo ward. The main objective of the meeting was to facilitate a discussion with different actors such as Mtaa Executive Officers  (MEO), Chairmen of the Subward, Councilors, Wajumbe leaders, Non Governmental Organizations and Community Based Organizations such as Tegemeo. Tegemeo provide education to the community on topics such as environmental education and how to support orphans – it operates nationwide.

During this meeting, community members pinpointed assets that they considered to be the most valuable within the Subwards and any possible threats to these assets perceived by the community. This information  allows Ramani Huria to produce a flood resilience plan. The maps will be the outputs produced after the information has been collected and organised using open source software.

Photo- Ward Leaders reading maps to identify their residences.

Community meetings were conducted with different key actors in the sub ward. Attendees included; Mtaa Executive Officers (MEO), Sub ward Chairmen, Councilors Wajumbe, Ten cells Shina Leaders, NGO and CBO partners (such as Tegemeo Wajumbe), government officials, private sector organisations, and religious leaders.

“I’m happy to be part of this, Knowing what is being done in my ward, participating in identifying safe and unsafe areas on a map can be a good start toward better planning” Mazoea Ling’omba- Mjumbe, Kigogo Kat subward.

The meeting was participated by 43 members from the two subwards, with participatory community meetings conducted in groups of 5 to 6 members. The exercise began by training participants how to read the map by identifying main features in the Subward and locating their area of residence. By the end of the group discussions participants were able to locate their houses and update street names on the map where information was missing or incorrect.

Photo; Maps are being updated by adding the missing information, risk areas are being identified  with the important asses in the ward.

“I’m proud to be part of this process – I have been trained  on how to read maps, and putting important things on a map to improve information for flood reduction” Miraji Simba- Red Cross Coordinator.

The most important lesson learnt from the workshop meeting is that it is the community members who are the key people needed to create a resilience plan. They are the ones who can identify historical flood trends and the location of key risk areas. (ie an engineer may be able to pinpoint flood risk areas based on calculations, but cannot provide the scope, history and impact of the flooding)- The information provided by community members allows a more accurate impression of the trend of flooding to be created with better understanding of how flood events have evolved over time.

Community members and Ward leaders were more reassured and excited about the project when they understood that the flood resilience plan was not intended to relocate people from their residence but rather to build a better plan on how to reduce flooding and suffering related to flooding.

“Initially my neighbors and I were a little worried that our houses may be demolished, but now we are at peace because the project was well explained to us. I will go and explain to ‘my people’ in the Shina to reassure them that the project is based on planning for resilience” Mjumbe- (Anonymous).

In these two Sub wards the main flood problems identified by community members were similar because the overall Ward is located between two major rivers, Msimbazi river and Kibangu river, that are ‘famous’ for causing flooding. It is clear that if the plans for flood resilience focus on accommodating people’s suggestions on the major community assets at risk and historical flood prone areas – improved mitigation plans can be produced which will reduce the effects of flooding.

Mkutano ulifanyika kwenye mitaa miwili ya kata kigogo kama majaribio ili kuona ni jinsi gani taarifa za wanajamii zinaweza kuutumika kutengeneza mpango huu.

Picha; Mkutano na Wana jamii.

Tarehe 26 mwezi wa tatu 2018, Timu ya HOT Tanzania ilifanya mikutano ya majaribio kwenye mitaa ya Mbuyuni na Kigogo kati. Lengo kubwa la mkutano ilikuwa kuhamasisha majadiliano na wadau mbalimbali kama Mtendaji wa mtaa, Mwenyekiti wa mtaa Wajume, Asasi zisizo za kiserikali na mashirika ya kijamii kama Tegemeo. (Tegemeo ni shirika linalotoa elimu kwa jamii kwenye mambo ya elimu ya mazingira na kusaidia yatima- Inafanya kazi nchi nzima.

Kwenye mkutano huu, Wanajamii walionyesha maeneolvitu ambavyo wanaona vina thamani sana kwenye mitaa yao. Taarifa hizi zitawezesha Ramani Huria kutengeneza mpango wa kupambana na mafuriko. Ramani hizi zitakuwa ni zao lililotokana na taarifa zilizokusanywa wakati wa mkutano na kupangiliwa kwa kutumia programu ya huru kama QGIS.

Picha- Viongozi wa mtaa wanasoma ramani na kuonyesha makazi yao.

Ninafurahi kuwa sehemu ya zoezi, Kujua nini kinaendelea kwenye mtaa wangu, kushiriki kwenye kutambua maeneo salama na yasiyo salama kwa kutumia ramani ni mwanzo mruri ili kutengeneeza mpango wa kupambana na mafuriko” Mazoea Ling’omba- Mjumbe, Mtaa wa Kigogo Kati.

Mkutano ulihudhuriwa na washiriki 43 kutoka mitaa miwili, kwa mikutano shirikishi iliyo huisha makundi ya watu wanne hadi watano. Zoezi lilianza kwa kuwaelekeza washiriki jinsi ya kusoma ramani, kuonyesha maeneo muhimu na kuonyesha makazi yao. Mwisho wa majadiliano washiriki waliweza kuonyesha nyumba zao na kuongeza majina ya mitaa ambapo kulikuwa hakuna taarifa au hazikuwa sahihi.

Picha; Ramani zinaboreshwa kwa kuongeza taarifa zilizo kosekana, maeneo hatarishi yana onyeshwa kwa vitu muhimu kwenya mtaa..

“Najivunia kuwa sehemu ya mchakato huu- Nimepewa  mafunzo ya jinsi ya kusoma ramani, na kuweka vitu muhimu kwenye ramani kuboresha taarifa kwa ajili ya kupambana na mafuuriko” Miraji Simba- Mratibu Red Cross.

Somo muhimu lililo jifunzwa kutoka kwenye warsha hii ni kuwa wanajamii ndio watu muhimu katika kutengeneza mpango huu. Wao wanaweza kutoa historia na mwenendo wa mafuriko na kuonyesha maeneo yaliyo kwenye hatari ya kupata mafuriko ( Kwa mfano mhandisi angeweza kujua ni wapi kuna mafuriko kwa kutumia mahesabu, lakini hawezi kutoa wigo historia na athari halisi za mafuriko)- Taarifa walizotoa wanajamii zinaonyesha mwonekano halisi na mwenendo wa mafuriko na kutoa uelewa zaidi wa jinsi mafuriko yalivo badilika kulingana muda.

Wana jamii na viongozi wa kata walijihakikishia na walikuwa na furaha kuhusu mradi huu pale waliposikia kuwa mpango huu wa kupambana na mafuriko hauhusishi kuwahamisha kwenye makazi yao bali kutengeneza mpango mzuri wa jinsi ya kupunguza mafuriko na na mateso yatokanayo na athari za mafuuriko.

Mwanzoni mimi na jirani zangu tulipta wasiwasi kuwa nyumba zetu zitabomolewa, lakini sasa tuna amani kwa  kuwa mradi umeelezwa vizuri kwetu. Nitaenda kuwaelezea “watu wangu” kwenye shina ili kuwahakikishia kuwa mradi huu ni kwa ajili ya mpango wa kupambana na mafuriko na si kuvunja nyumba”Mjumbe- (jina limehifadhiwa).

Kwenye mitaa hii miwili, matatizo yote yaliyo onyeshwa na wana jamii yanafanana kwa sababu Kata nzima ya kigogo ipo kati ya mito miwili mikubwa- mto  Msimbazi na Kibangu ambayo ni mito “maarufu” inayosababisha mafuriko. Ni wazi kuwa mpango huu wa kuzuia mafuriko unalenga kwenye kuweka mapendekezo ya wana jamii ya vitu vya muhimu ambavyo vipo kwenye hatari ya kupata mafuriko na historia ya maeneo yanayopata mafuriko- Mpango ulioboreshwa wa kupunguza athari za mafuriko unaweza kutengenezwa.


Mapping Bicycle Routes During Dar es Salaam’s Cycle Caravan

Each year, 5th June marks World Environment Day, a day for raising global awareness to take positive environmental action to protect nature and the planet Earth. This year’s Sunday 5th June saw UWABA (Umma wa Wapanda Baiskeli; or “Public Cycling Community”), a cycling community in Dar es Salaam in cooperation with European Union, organizing the cycle caravan. This is to support low carbon transport, to promote environmental alternatives to high carbon transport as well as putting emphasis on the presence (or absence) of bicycle roads/routes in the city.

With the motivation to do the mapping for the city, Ramani Huria fully participated to support the initiatives by UWABA community and map the possible bicycle routes around the city. This was done through tracking the caravan’s route with the use of GPS unit tied on the bicycle.

The event was scheduled to start at 7 AM at the Mnazi Mmoja grounds with registration of the participants, provision of free reflector jackets, bicycle helmets and bicycle reflectors to all participants.

After all attendee arrives, including January Yusuph Makamba, a minister of State in the Vice President’s Office for Union Affairs and Environment, the caravan started at 08:45 AM. The route went along Bibi Titi road, Ohio Street, Sokoine Driveway, Chimara Street, Barack Obama Drive to Agha Khan Hospital, where people had short break to catch their breath. After that, the caravan continued to Salender Bridge and took the United Nations Road to Morogoro Road (Fire Squad Headquarters), followed the Morogoro Road and caught Lumumba road back to Mnazi Mmoja.

Throughout the process, the routes used for the caravan were basically not only meant for cycling purposes, but rather, they were roads for general uses such as cars, motorcycles etc. With the escort and support from traffic police, cars within the major roads were blocked leaving clear way for the caravan to go through. This isn’t an everyday occurrence, with cyclists usually competing for space with traffic.

Back at Mnazi Mmoja, while attendees had snacks and water to eat and drink, Mr. Mejah Mbuya, chairperson for UWABA gave a short speech on the importance of using bicycles as low carbon transport around the city. With the fact that Dar es Salaam is much affected by traffic jams, Mr. Mbuya emphasized on the use of bicycles to minimize it.

Ramani Huria is looking forward to joining forces with UWABA in mapping and promoting low carbon transport i.e bicycle usage throughout Dar es Salaam.[:sw]Kila mwaka,tarehe 5 juni inawakilisha siku ya mazingira duniani, siku ya kuhamasisha ulimwengu kuchukua hatua chanya kimazingira za kutunza hali  na sayari ya dunia. Mwaka huu tarehe 5 juni

Tulishuhudia UWABA (Umma wa Wapanda Baiskeli),jumuiya ya waendesha baiskeli Dar es Salaam wakishirikiana na umoja wa Ulaya, waliandaa msafara wa kuendesha baiskeli. Hii ilikuwa na lengo la kusaidia kupunguza hewa ya ukaa, kuhamasisha njia mbadala ya  kupungza usafiri unaotoa hewa ya ukaa pia na kuweka msisistizo katika kuwepo (au kutokuwepo) kwa njia za baisikeli katika jiji.

Katika kuhamasisha kutengeneza ramani ya jiji, Ramani Huria walishiriki kikamilifu kwenye mipango ya jumuiya ya UWABA na kutengeneza ramani ya njia za baiskeli zilizopo katika  jiji. Hii ilifanyika kwa kufuatilia msafara wa baiskeli kwa kutumia kifaa cha GPS ambacho kilifungwa kwenye baiskeli.

Baada ya washiriki wote kufika, akiwemo waziri wa nchi ofisi ya makamu wa raisi muungano na mazingira Mh. January Yusuph Makamba,msafara ulianza saa 2:45 asubuhi.Msafars ulipitia barabara ya Bibi titi mtaa wa Ohio,barabara ya Sokoine, mtaa wa Chimara, barabara ya Barack Obama kuelekea hospitali ya Agha Khan, ambapo kulikuwa na mapumziko mafupi. Baada ya hapomsafara uliendelea kuelekea daraja la Salender na kupitia barabara ya umoja wa mataifa kuelekea barabara ya Mororgoro (makao makuu ya zima moto) na kupitia barabara ya lumumba kurudi mnazi mmoja.
Muda wote wa zoezi, njia zilizotumiwa na msafara hazikuwa kwa ajili ya waendesha baiskeli,bali zilikuwa ni barabara za matumizi mbalimbali kama vile magari pikipiki n.k.kwa msaada wa polisi wa barabarani magari yalikuwa yanatumia barabara kubwa yalizuiwa ili kupisha msafara

Ramani Huria inatarajia kushirikiana na juhudi za UWABA katika kutengeneza zamani na kuhamasisha utumiaji wa usafiri unaozalisha hewa ndogo ya ukaa kama vile matumizi ya baiskeli ndani ya jiji zima la Dar es Salaam.


How are the maps being used in the wards?

[:en]Guest post by Mercedes Hoffay, Master of Public Administration Candidate – Columbia University

All policy students are obsessed with the effectiveness and feasibility of policies and programs that governments implement. So when we find a tool that allows significant efficiency gains in government planning, we are thrilled. That is how we felt when we embarked on our Graduate Capstone Project to evaluate the Humanitarian OpenStreetMap Team’s work in Tanzania and their role in Dar Ramani Huria.

Let me introduce ourselves: we are six Masters students from Columbia University, studying Public Administration, International Affairs and Public Health, all of us from different backgrounds and countries but with a focus on development. As part of our graduate degree, we need to conduct a consultancy project with a client, and that’s how we met HOT and their amazing team. They were interested in having us evaluate the implementation of community mapping in Dar es Salaam, how those maps are being used by the different stakeholders and to assess the sustainability of the project. With this in mind, we decided we needed to talk to those who were the main target users of the maps by the project: the ward officers, which are the local authorities for the neighborhoods or wards.

When we arrived in Dar es Salaam we clearly understood what the lack of maps meant. It was hard for us to know how to go from point A to point B, and to find where the places that we should go were located. In a city that is 70% unplanned and changing fast, this translates into inappropriate infrastructure, insufficient services, and spillover problems like floods and spread of diseases.

During our visit we got to interview three ward officers, Mr. Osiligi from Tandale, Mr. Nunga from Mabibo and Mr. Mishekh from Buguruni, and an Mtaa or sub-ward officer, Mr. Mwisongo from Ndugumbi. Our first meeting was with Mr. Osiligi from Tandale, who is one of the champions of Dar Ramani Huria. As soon as we stepped into his office we saw the maps proudly displayed on his wall. He kicked off our conversation by saying: “the maps are a place to start. Without the maps, it’s like being blind”. He went on to explain how he was going to use the maps for presenting projects to the municipality, to plan roads and drainage investments. And he also told us how he used them to respond to a cholera outbreak by clearly pointing out to the health authorities where the foci of infection were located.

Using the maps for planning was a recurrent theme in all our interviews. Since planning is a very general term, when we asked for clarification the answers revolved around infrastructure projects such as roads, drainages, water and sanitation, but also planning for better provision of public services such as health centers and schools. One ward officer even said that with a clear map of the residential and public buildings, he could also easily identify good spots for recreational areas and request funding accordingly. The maps can also be used for disaster response after floodings occur. One of our interviewees explained how the maps could help him estimate the number of people potentially affected during the next flooding season and what are the best roads to access those flood-prone areas with aid.

You are probably asking yourself, but didn’t the ward officers know this information before having the maps? After all, they probably know the place they are working at even without a map, right? Well, yes and no. We found out that new ward officers were being appointed and they were not necessarily from the ward. And the maps are the only piece of information that has every single road and passageway of the neighborhood. This allows for significant efficiency gains by giving the newcomers a better sense of direction and the details of the terrain where they are working. In fact, one of the officers we interviewed was new, and was very happy about how he could actually know where things are located and how to move from point A to point B.

Overall, the ward officers seemed to understand how this practical tool can help them improve their daily operations and, at the same time, allow them to plan in advance. However, as one of the ward officers put it, it’s still too early to measure results and how effective the maps are in allowing for better planning. We would love to see how all these cases fare down the road after a few years of existence of the maps. We have faith that all ward officers will embrace the maps and continue to put them to good use.[:sw]Imeandikwa na Mercedes Hoffay, mwanafunzi wa Digrii ya uzamiri ya utawala wa umma- Chuo kikuu cha Columbia.

Wanafunzi wote wa sera  wanahofu  na ufanisi na upembuzi wa sera na mipango ambayo serikali inapanga kutekeleza.Hivyo tutakuwa na furaha endapo serikali itapata  chombo kitakacho rahisisha  ufanisi na kuleta mafanikio makubwa katika mipango ya serikali.Na hivyo basi tukaona ni muhimu kuliingiza katika taaluma yetu na kutathmini lengo kuu la mradi na kazi ya Humanitarian OpenStreetMap  ya Tanzania na wajibu wao katika Dar Ramani Huria

Nianze tu kwa utambulisho wetu, tupo wanafunzi sita tuna some digri ya uzamili chuo kikuu cha Colombia, tunasome kozi zifuatazo Utawala wa Umma,Masuala ya Kimataifa na Afya ya Umma, sisi sote kutoka asili na nchi mbalimbali  lakini kwa lengo moja la maendeleo. Kama sehemu yataaluma yetu, tunahitaji kufanya ushauri wa mradi na mteja, na vilevile  kukutana na   timu yao ya maajabu ya HOT. Walikuwa nia ya kuwa na sisi katika  kutathmini utekelezaji wa ramani ya jamii jijini Dar es Salaam, na jinsi ramani zinatumiwa na wadau mbalimbali na  kutathmini uendelevu wa mradi.Hivyo basi, sisi tuliamua kuwa kunauhitaji wa  kuzungumza na wale ambao walikuwa walengwa na  watumiaji wakuu wa ramani katika mradi; Maafisa kata, ambao wawakilishi wa serikali za mitaa kwa ajili ya mitaa au kata.

Tulipofika jijini Dar es Salaam tulielewa wazi nini maana ya ukosefu wa ramani. Ilikuwa ni vigumu kwetu kujua jinsi ya kwenda kutoka sehemu A mpaka B, na kupata ugumu wa  maeneo ambayo tulipaswa kwenda. Katika mji huo zaidi ya  70% ni makazi holela na una mabadiliko ya  haraka, hii inasababisha kuzidiwa kwa  miundombinu , huduma za haitoshi, na matatizo mengine  kama mafuriko na kuenea kwa magonjwa.

Wakati wa ziara yetu tulipata kuwahoji maofisa kata wa tatu, Mheshimiwa Osiligi kutoka Tandale, Mheshimiwa Nunga kutoka Mabibo na Mheshimiwa Mishekh kutoka Buguruni, na  Afisa wa mtaa , Mheshimiwa Mwisongo kutoka Ndugumbi.Mkutano wetu wa kwanza ulikuwa na Mheshimiwa Osiligi kutoka Tandale, ambaye ni mmoja wa mabingwa wa Dar Ramani Huria. Kwa haraka tulipoingia  katika ofisi yake tuliona ramani zime bandikwa kwenye ofisi yake na akajigamba kwa kufurahia kilicho fanywa na mradi.Alianza mazungumzo kwa kusema “ramani ni mahali pa kuanza. Bila ramani, ni kama kuwa kipofu “.Aliendelea kueleza nijinsi gani atakuwa anaenda kutumia ramani kwa kuwasilisha miradi ya manispaa, kupanga barabara na uwekezaji mifereji ya maji. Pia alitueleza jinsi alivyotumia ramani katika kukabiliana na kuzuka kwa kipindupindu na kuelekeza  mamlaka ya afya chanzo kilipo.

Mheshimiwa Osiligi akieleza  namna ya kutumia ramani katika Tandale wodi ofisi, Machi 2016

Matumizi ya ramani kwa ajili ya kupanga ilikuwa mada ya kawaida katika mahojiano yetu yote. Pamoja na neno mipango kuwa na uelewa mpana , wakati tulipouliza kwa ufafanuzi majibu yaligusia miundombinu kama vile barabara, mifereji, maji na usafi wa mazingira, lakini pia kupanga kwa ajili ya utoaji bora wa huduma za kijamii kama vile vituo vya afya na shule. Moja wa afisa kata alisema kuwa pamoja na ramani ya majengo ya makazi na umma, angeweza pia  kutambua kiurahisi maeneo mazuri kwa ajili ya maeneo ya burudani na kuomba ufadhili ipasavyo. Ramani pia inaweza kutumika kwa ajili ya kukabiliana na maafa hayo baada ya mafuriko kutokea. Moja ya waliohojiwa  alieleza jinsi gani angeweza kutumia  ramani na  kumsaidia kukadiria idadi ya watu ambao  wangeweza kuathirika wakati wa mafuriko ya msimu ujao na ni barabara gani bora ya kufikia maeneo hayo mafuriko na misaada endapo yatatokea.

Labda unaweza kujiulia  mwenyewe, je maafisa kata  walikuwa hawana taarifa  hizo kabla ya kuwa na ramani? Baada ya yote,  pengine wao waliweza kujua sehemu wanafanya kazi hata bila ramani, kwa uhakika? Naam ndio au hapana.Tuligundua kwamba maafisa mpya wakata walikuwa wakuteuliwa na walikuwa si lazima kutoka kata husika. Na ramani ni kipande tu cha habari kwamba ina kila barabara moja na geti ya jirani. Hii inawapatia mafanikio makubwa  na ufanisi kwa kuelekeza wageni hali muonekano wa ardhii ya eneo wanalofanyia kazi. Kwa kweli, mmoja wa maafisa waliohojiwa alikuwa ni  mpya, na alikuwa na furaha sana kuhusu jinsi gani angeweza kujua vitu na mahali vilipo na atatokaje sehemu A na kwenda sehemu B.

Kwa ujumla, maofisa kata walionekana kuelewa jinsi chombo hiki kinavyoweza kuwasaidia kuboresha shughuli zao za kila siku na, wakati huo huo, kuwaruhusu kupanga mapema.Hata hivyo,mmoja wa maafisa kata alibainisha, bado ni mapema mno kupima matokeo nakujua  jinsi ufanisi ramani utaweza kuruhusu mipango bora. Tungependelea kuona jinsi matukio haya yote yatatokea baada ya miaka michache ya kuwepo kwa ramani.Tunatumaini  kwamba maafisa wote wa kata wata kumbatia ramani na kuendelea kuziweka kwa matumizi mazuri.[:]

Community mapping presented to UDSM Masters students

[:en]Ramani Huria was excited to be invited by the University of Dar es Salaam (UDSM) to present on digital community mapping to GIS Masters students on 29th of February, 2016. The session was facilitated by Dr. Festus Ndumbaro, university lecturer on Cartography and GeoVisualization. Ramani Huria presented on ‘Web Maps’ and led a discussion with the students, allowing for knowledge transfer between graduated and current students from UDSM.

The Ramani Huria team began by giving an overview of community mapping they are facilitating on Dar es Salaam, with the focus on flood resilience. We explained how we conducted mapping, with students and community members, and some of the challenges and opportunities experienced thus far. Following this, we introduced OpenStreetMap (OSM) to the students, including some of the key principles of open source, that the map is free for all to use and reuse. The students were particularly interested in the differences between OpenStreetMap and Google Maps. The team explained that Google requires you to have a license in order use their map data, OSM on the other hand is free to use as long as you credit OSM.

Aerial imagery was also discussed with the students, Ramani Huria uses imagery we have captured ourselves with drones (mbtiles), Bing, and DigitalGlobe imagery. A student noted that the drone imagery captured by Ramani Huria is much clearer than other providers.

Following the session, students noted that they were very interested to learn more and requested the Ramani Huria return and present on additional topics, including JOSM and other tools to allow them to map and process data for their neighbourhoods. The facilitating lecturer, Dr. Ndumbaro, encouraged the students to spend some time to explore and experiment with OSM, learning the tools and mapping their own communities.

We found the students to be engaged and enthusiastic, asking many questions about all the topics raised through our presentations. At the end of the session they were left with a thorough and holistic knowledge of the work of Ramani Huria and OpenStreetMap.

The day was a great opportunity to share our mapping skills and experience with a new audience and continue our excellent relationship with the university, particularly the Department of Geography.[:sw]Ramani Huria walikuwa na furaha kualikwa na Chuo Kikuu cha Dar es Salaam(UDSM) kuwasilisha Jinsi ya kuhusisha jamii katika utengenezaji wa ramani kwa digitali kwa wanafunzi wa shahada ya  Uzamili tarehe 29, Februari, 2016. Kipindi  kiliendeshwa na Dr. Festus Ndumbaro Mhadhiri wa masomo ya kutengeneza Ramani na Taswira. Ramani Huria iliwasilishwa kwa ramani za mtandao na kuruhusu majadiliano na wanafunzi, kubadilishana maarifa kati ya wahitimu na wanafunzi  kutoka chuo kikuu cha  Dar es Salaam.

Timu ya Ramani Huria ilianza kuelezea kwa  ujumla jinsi walivyotekeleza zoezi la kushirikisha jamii kuandaa ramani katika mkoa wa Dar es Salaam ikiwa na lengo la kuzuia Mafuriko. Tulielezea namna tulivyokusanya taarifa kwa ushirikiano na  wanafunzi pamoja na  wanajamii, na baadhi ya changamoto na fursa tulizoziona. Tulifundisha OpenStreeMap (OSM) kwa wanafunzi, tukijumuisha kanuni za kutumia vyanzo wazi, kuwa Ramani ni huru kila mtu anaweza kutumia. Wanafunzi walionyesha nia ya kujua tofauti kati ya OpenStreetMap na Ramani za Google.Timu ilieleza kuwa Google inahitaji mtu kuwa na leseni kwa ajili ya matumizi ya Ramani, wakati OSM ni  bure kutumia cha msingi kufungua akaunti.

Vile vile picha za Anga zilizongumziwa na wanafunzi . Ramani Huria wanatumia picha walizopiga wenyewe kwa kutumia drone(mbtiles), Bing na Digital Globe. Wanafunzi waligundua kuwa picha za anga zilizopigwa na drone inaonekana vizuri kuliko nyingine.

Kutokana na kipindi, wanafunzi walionekana wana shauku kubwa sana ya kujifunza zaidi kuhusu Ramani Huria hivyo waliomba wawezeshaji  warudi na kuwafundisha mada nyingine zaidi, ikiwa ni pamoja na JOSM na zana nyingine ambazo zitawasaidia katika mchakato wa kukusanya taarifa na kuandaa ramani katika maeneo yao. Dr Ndumbaro, Ambaye ni mhadhiri aliwatia moyo wanafunzi kutumia muda wao kuchunga na kufanya majaribio ya OSM, kujifunza zana na kuandaa ramani katika jamii zao

Pia tuligundua kuwa wanafunzi wana shauku kubwa ya kujifunza ambapo waliuliza maswali mengi kutoka katika mada tulizoziwakilisha. Mwisho wa  kipindi wanafunzi walikuwa na uelewa wa  jinsi Ramani huria na Openstreetmap zinavyofanya Kazi

Hii ilikuwa ni siku kubwa kwetu ambapo tulipata fursa ya kuwashirikisha ujuzi na uzoefu wetu kwa  wasikilizaji wapya pamoja na kuendeleza uhusiano wetu mzuri  na Chuo kikuu cha Dar es salaam, hasa idara ya jiografia[:]
