Data Collection for the Small and Medium Agribusiness Development Fund (SMADF)

The SMADF is a partnership between public and private investors which aims to stimulate the growth of Small and Medium Agri-businesses (SMAs) by providing them with long-term financing products. The aim of the SMADF is to invest in SMAs so that they expand their operating capacity, which is then expected to increase the demand for smallholder goods, services and labour, thus stimulating an increase in smallholder income.

The impact assessment will be based on quantitative and qualitative data collected from smallholder households, and on qualitative data collected from smallholder households, beneficiary SMAs, and from SMADF staff. Approximately 3,000 households will be interviewed across 10 SMAs, in Uganda. In each SMA 300 households will be interviewed as part of the quantitative data collection. In addition, five KIIs and two FGDs will take place in each SMA.

Uganda Farm and Family Balance Study

The International Food Policy Research Institute (IFPRI) and the World Bank are conducting a randomised controlled trial to examine ways to promote women’s participation in cash crop agriculture in Uganda. The experiment will employ a cross-cutting design with a sample of households engaged in contract farming with a large-scale sugarcane processing company based near Jinja, Kakira Sugar Limited.

Two interventions will be examined: i) a household-level intervention to provide cash or in-kind incentives to men to transfer (or newly register) an outgrower contract (contract farming) in the name of his spouse; and ii) a sensitisation workshop intervention – conducted at the village level – to promote gender equity and cooperation within outgrower households. The cross-randomisation design will yield estimates of the impact of each of these interventions separately and the combined effect of the two – relative to the pure control group. The World Bank contracted EDI as the survey firm to work with the Evaluation Team to implement the baseline survey in 2016.

EDI’s teams conducted fieldwork in villages located in five districts in the Eastern Region of Uganda: Iganga, Jinja, Kamuli, Luuka, and Mayuge. EDI successfully completed 2,370 household interviews.

Measuring Household Labour in Smallholder Farming

In Sub-Saharan African farms, family labour is the major farm input and having a good measure of it is critical.  This project assessed the degree of measurement error in reporting household labour inputs in farming and the analytical implications of this error.  The methodological study collected information about labour for every member of farm households in a sample of villages in Tanzania during the 2013/2014 agricultural season. The experiment focused on three alternative survey designs: Control Group (C): Standard agricultural labour module, with labour reported in the aggregate by recall for the entire season (End-line Survey).  Treatment Group 1 (T1): Baseline Survey and phone surveys for labour module for the duration of the main season (Mobile phone survey). End-line Survey fielded to capture completed agricultural season yields and other inputs.  Treatment Group 2 (T2): Baseline Survey and intensive interview labour module during the duration of the main season (Time Use survey). End-line Survey fielded to capture completed agricultural season yields and other inputs. GPS location data was collected for all households and in addition, GPS data were used to calculate the area of farm plots. 

Data was successfully collected and cleaned by end of September 2014, and is currently being analysed.  Two research papers/policy brief are being produced using the data from the experiment. These papers should be completed during 2015.

Tanzania Africa RISING Baseline Evaluation Survey (TARBES)

As part of the US government’s Feed the Future initiative that aims to address global hunger and food security issues in sub-Saharan Africa, the US Agency for International Development is supporting multi-stakeholder agricultural research projects under Africa Research In Sustainable Intensification for the Next Generation (Africa RISING – AR) program.  The overall aim of the program is to transform agricultural systems through sustainable intensification projects in three regions of Africa. In this project, EDI collected baseline household and community data in Babati, Kongwa, and Kiteto districts in Tanzania for the purpose of facilitating M&E of Africa Rising-Tanzania project.  Baseline geo-coded household data was collected from ‘baby’ farmers in the intervention villages, with household survey data also collected from counterfactual villages. In addition to the household survey, a community survey was conducted using a short structured community questionnaire from key informants and/or village leaders. 





Impact Evaluation: ‘CHANGE’ Programme

The objective of the study is to evaluate the impact of two different versions of an enhanced homestead food production program implemented in Burkina Faso and Tanzania by Helen Keller International. At baseline the household survey was conducted to collect information on household demographics, socio-economic characteristics, production and consumption, household food security, health & nutrition plus related knowledge and practices. In addition anthropometric measure of the target children and mothers were recorded. Capillary blood samples were taken from children to assess the children’s haemoglobin status, presence of malaria, and to conduction additional biochemical analyses. The households and respondents will be followed up over the course of the intervention period. The research was conducted in both English and French with survey support from EDI UK and Surveybe.

Technical Support to the Uganda National Panel Survey 

Through an ongoing collaboration with the World Bank Living Standards Measurement Study – Integrated Surveys on Agriculture (LSMS-ISA) project, EDI worked with the Uganda Bureau of Statistics (UBoS) in moving from paper based questionnaires to CAPI for the second wave of the Uganda National Panel Survey (UNPS). The UNPS is a panel survey being carried out annually on a nationally representative sample of approximately 3000 households. The survey is conducted through two household visits per year in order to capture the two cropping seasons of the country. The UNPS is comprised of the following modules:

-Household (demographics, education, labour, health, consumption, assets, income & enterprises, housing conditions, child health & nutrition, shocks & food security)

-Agriculture (planting, production, inputs)


-Community/Facility Questionnaires (education, roads & transport, health facilities, water & sanitation)

Staff at UBos were fully supported during the 2nd wave of the study by EDI and received training to enable them to design their own electronic surveys in Surveybe for the 3rd wave of the National Panel Survey.

Gender and Adolescence: Global Evidence (GAGE)

This exciting, nine-year, multi-country longitudinal research initiative working in the Global South which aims to strengthen the evidence base on adolescent girls – as individuals and as future women– to maximise their capabilities and shape their own futures.  GAGE research will focus on what policies and programmes work, where and why. It will identify the medium and long-term impact of interventions for girls, and ascertain how best to time and sequence those interventions.

The consortium, including Economic Development Initiatives (EDI) Limited as a consortium partner, will produce a global body of evidence, based on data gathered through innovative approaches over a sustained period which will go beyond current frameworks to advance the well-being of adolescent girls.

We will undertake an in-depth, mixed-methods programme of longitudinal research in four focal countries in Africa and Asia, balancing a mix of ‘gold standard’ impact evaluation approaches with innovative implementation and action research.  EDI will provide expertise in the development and configuration of the data collection instruments and fieldwork protocols.  We will lead training sessions in country and help to guide the consortium through the data collection phases using our powerful, sophisticated surveybe software.

The EDI data hub will be responsible for data processing and data cleaning as data is collected in all four countries.  Our team will liaise closely with local country partners to identify and resolve data queries in near-time.  Finally, EDI will provide the consortium partners with the final dataset by country for analysis.

Impact Evaluation of the Urban Local Government Strengthening Program (ULGSP)

The Urban Local Government Strengthening Program (ULGSP) in Tanzania aims to address the sources of challenges to service delivery by improving the institutional capacity for urban service delivery and by strengthening accountability systems in 18 urban local government authorities.

The program leverages a performance for results instrument to enhance institutional performance in 5 key areas: urban planning, own source revenue collection, fiduciary systems, urban infrastructure service delivery and accountability and oversight systems.
The goal of the Impact Evaluation (IE) is to produce evidence about the impact of greater capacity on governance outcomes. Governance outcomes are very different from outcomes that are measured in other sectors as part of impact evaluation work, such as, for example, the impact of a health project on objective indicators of health outcomes among children. Governance outcomes are difficult to measure in objective ways. Self-sufficient urban local governments whose officials work together in effective teams to plan, raise resources, deliver services, and win the trust and cooperation of the people, are examples of such outcomes.

The IE will use two survey instruments to gather data on the perceptions and self-reported experience with governance outcomes of two key stake-holders—the citizens (households) and the local public officials. The data gathered by EDI will examine whether the citizens and local officials that reside and work in local governments with greater institutional capacity report different beliefs, perceptions and experience with governance than those in areas with less institutional capacity. Such evidence in turn will allow the government to work with international development partners to invest in effective capacity building that delivers outcomes on the ground.

Uwezo Follow Up Survey

Twaweza is a ten year citizen-centered initiative (, focusing on large-scale change in East Africa that seeks to foster conditions and expand opportunities through which citizens can get information and make change happen in their own communities directly and by holding government to account. As part of the evaluation of Twaweza’s first strategic period (2009-2014) and in collaboration with the Amsterdam Institute of International Development (AIID), Twaweza conducted a nationally-representative survey of 2,500 households throughout Tanzania. The survey collected data on an extensive set of indicators related to citizen agency and government responsiveness particularly in the education, health and water sectors.

(the highlights of the findings can be found here  In 2015, EDI conducted a follow up survey of the same households interviewed in 2009.





Public Opinion Study of Natural Resource Management Revenues in Tanzania

In 2010, Tanzania discovered natural gas reserves off its southern coast worth roughly fifteen times its annual GDP. This project assesses the ability of Tanzanian voters to formulate coherent views on a range of options for the use of gas revenues – including a sovereign wealth fund, revenue sharing with regional governments, and direct distribution in the form of cash transfers. The sample is 2000 nationally-representative respondents in 20 districts in Tanzania, who are divided into control and treatment groups. The intervention consists of a “deliberative polling” exercise to be held in Dar es Salaam in April 2015. This will be a series of public deliberations with a nationally representative sample of ordinary Tanzanians, where respondents will be exposed to expert information and public debate. Baseline surveys were conducted prior to the deliberative poll for both the control and treatment group. Two rounds of follow-up phone surveys will be conducted after the poll to assess whether respondents have changed their opinions and their level of public engagement.  EDI is responsible for the design and implementation of the survey in Tanzania.

Feb-Oct 2018 Randomised Controlled Trial of Off-Grid Solar Power Project

In 2016 JICA signed an agreement with Digital Grid Inc. for the Off-Grid Solar Powered LED lantern renting service. This business installs solar panels at kiosks in villages without electricity, and provides LED lamp rental services and mobile phone charging services at the kiosks. The LED lamps are safer, brighter and less expensive than kerosene lamps.

The use of LED lamps is expected to curb household expenditure by replacing kerosene lamps, improve health conditions, increase children’s study hours and reduce greenhouse gases. It is expected that retail shop owners will be able to extend shop opening times and possibly create new business activities. In order to verify these impacts, JICA is running a randomised controlled trial.

EDI is conducting data collection for two questionnaires: a Kiosk Owner Survey and Customer Survey.

March-Aug 2017 Tanzania Competitive Industries Workstream #2

The scope of this work is to understand the importance of management practices for medium to large manufacturing firms and to compare Tanzanian firms to firms around the world. The focus is to better understand the type of support required for firms to upscale production, improve quality, and in many cases, prepare to become exporters.

The survey will identify issues relating to production, management, technology, and quality of manufacturing industries whilst reviewing the role of management in accounting for variations in firms’ productivity, profitability, and employment. The results from this survey will be used to provide some preliminary evidence on the cause of the difference in management practices in Tanzania.

Conducted by EDI, on behalf of a joint group from the London School of Economics and the World Bank Group, the survey involves tracking firms as well as an identified representative thereof, who will be interviewed. The representative will be a senior member of staff with sufficient knowledge of the firm but not so senior that they are out of touch with the day to day operations of the firm.  A minimum of 125 firms will be surveyed across Tanzania. The survey tool involves qualitative aspects, coded to give quantitative results, and a quantitative section. A short eligibility questionnaire is conducted over the telephone or in person whilst the main survey tool will only be conducted in person.

2016 Financial Inclusion Tracker Surveys (FITS) Project 

The Financial Inclusion Tracker Surveys (FITS) Project is a multi-year initiative by Bill & Melinda Gates Foundation (BMGF) to provide financial insights from a household level.  The topics covered include a focus on the impact of the expansion of “mobile money” – particularly using mobile phones to conduct bank transfers in developing countries – and how that affects a household’s financial behaviours.

A key research question is whether access to mobile money and lower transaction costs of sending money over long distances can help a household to manage economic shocks.

The FITS project has been undertaken in Tanzania, Uganda and Pakistan. EDI, in collaboration with IPA, undertook data collection on a national scale for wave 2 of the FITS project in Tanzania; tracking and revisiting 2,980 households from wave 1 throughout 300 Enumeration Areas.



2014 E-Verification Baseline Market Survey

EDI supported IFPRI in the development of an electronic survey instrument for this market survey in Uganda. The objective of the study is to evaluate the impact of using e-verification to reduce counterfeiting of agricultural inputs in Uganda. To this end three questionnaires were configured: a market survey, a community listing exercise (quasi-census) and a baseline survey of individual households. IFPRI collected the household survey data via mobile computers and using Surveybe software, with EDI support to design and enable multi-language questionnaires for each questionnaire.



2012 Improving Institutions for Pro-Poor Growth

Parental Engagement in Children’s Education in Tanzania (PECHET) Pilot Study

The goal of this pilot intervention is, through a series of meetings between parents and teachers, to boost parents’ efficacy in encouraging their children’s learning at home and at school. Ultimately, it may help to flatten the hierarchical power structure in the school community (Lieberman & Zhou, 2015).

The pilot baseline and endline surveys were conducted by EDI in 2016, across 24 schools in Bukoba Rural Districts before a potential scaling-up of the project based upon evidence provided by the data.  In total, 600 parents were interviewed in each of the rounds of the survey. The sample was structured as follows; 25 parents of students in Standard III were selected in 24 schools:

  • 8 Validated Participation schools (treatment arm);
  • 8 Information Workshop schools (control arm with information-only workshop), and;
  • 8 Survey only schools (control arm with no workshop).

At baseline and endline the 25 selected Standard III students from each school were given a 15 minute assessment on Kiswahili, English and Mathematics to see if increased parental engagement leads to better education outcomes.

EDI were also involved in four intervention workshops for 16 schools.  This included an introductory Intervention Discussion Session which was conducted alongside the baseline visit, two subsequent (weekly) visits to the school to undertake additional sessions and a final visit to coincide with the endline survey.

Validated Participation “One Shot” Treatment Design

This study is a follow-up of the Parental Engagement in Children’s Education in Tanzania (PECHET) study implemented previously by EDI in Bukoba in 2016 and aims to explore the effect of “validated participation” – positive feedback provided in the context of offering citizens opportunities to talk, debate, and make decisions – on feeling of self-efficacy and active participation in a school setting.

A total of 16 schools located in Kilosa district in Morgoro region were selected where 90-120 parents per school were invited and randomly allocated into three groups. Depending on the treatment group allocated, the parents view a video, are interviewed and participate in discussion sessions.

Girls’ Economic Empowerment Project, a Randomised Control Trial in Tanzania

In 2013, the Norwegian School of Economics (NHH) began implementing the Girls’ Economic Empowerment project, a Randomised Control Trial in Tanzania.  The programme selected 3,500 girls from 80 secondary schools across Tanzania (see map right).  The sampled girls were split into 4 study groups who received training either in heath, or in business skills or in both health and business skills or no training at all. Besides depending on the group, they received a different combination of additional training in their final months of Secondary School.

Prior to the intervention commencing, NHH conducted a baseline survey of all respondents and conducted follow up surveys immediately after the intervention and another 1 year later.  EDI conducted the third follow up survey in 2016.

The Girls’ Economic Empowerment survey included a phone interview for the 3,500 initial respondents, followed a few weeks later by a face-to-face interviews and medical testing. Respondents were tested for pregnancy, syphilis and malaria.

KiuFunza Implementation

The Twaweza initiative implemented two separate interventions that aimed to improve the channeling of resources to public primary schools for quality improvement of public education, and the restricting of incentives to improve learning outcomes of primary school students.

Twaweza collaborated with J-PAL to design a randomised control trial of 350 Public Primary Schools to evaluate and understand the effects of both interventions. Participating schools were randomly allocated to one of four study arms, and the interventions were rolled out in the treatment groups. In order to monitor these interventions, EDI undertook baseline and endline school and household surveys to collect school and teacher information as well as student and household information from randomly selected students from standard 1 to 3.

Midway through the interventions EDI also conducted two rounds of school monitoring visits to collect information on teacher attendance and activities within schools.

Experiments to Improve Learning Outcomes in Tanzania

Since early 2013, EDI have been collaborating with Twaweza and J-PAL to design and implement a randomized control trial to evaluate and understand the effects of two interventions at 350 randomly selected public primary schools across 10 districts in Tanzania. The interventions include a school grant as well as teacher incentives, which aim to improve the channelling of resources to public primary schools for quality improvement of public education, and the learning outcomes of primary school students respectively.  The baseline survey in early 2013 collected school and teacher information as well as student and household information from randomly selected classes, teachers, and students from standard 1 to 3.  Participating schools were then randomly allocated to one of four study arms, and the interventions were be rolled out in the treatment groups. In May/June and September 2013, two rounds of monitoring visits to schools collected information on teacher attendance and activities within schools. An end-line survey during late 2013 again collected teacher and school data, as well as information from students and households interviewed and tested during baseline.

We repeated similar surveys in the sampled schools during 2014, and are currently embarking on the design of the experiments with TWAWEZA and IPA/JPAL for 2015. You can read more about this experiment on the TWAWEZA website.

The Determinants of Schooling in Kagera Region – Sequential Quan/Qual Work

This project designed and implemented a qualitative instrument to look at the determinants of schooling in the KHDS clusters (see below). Very specifically it was geared towards understanding an empirical fact observed in the data, namely that villages with high ethno-linguistic fractionalisation performed worse in terms of schooling than those with low ethno-linguistic fractionalisation. The qualitative work was conducted to feed back into the quantitative work: to assess the likelihood of several possible scenarios to explain the empirical observation and determine strategies to test them in the data.

R4D, IDinsight, the Ministry of Health, Community Development, Gender, Elderly and Children (MoHCDGEC) and the National Institute for Medical Research (NIMR) among other partners, have been working with EDI to collect high quality, reliable data from a nationally representative sample of public health facilities and a subsample of Accredited Drug Dispensing Outlets (ADDOs) on the current state of pneumonia-related treatments. The intended outcome of this partnership is to increase access to effective treatment in the public sector, thereby helping to reduce pneumonia mortality among children in Tanzania.

EDI is conducting three rounds of data collection, all taking place in 2017. The total sample of health facilities involves 53 district hospitals, 50 health centers and 521 public dispensaries across all 26 mainland regions in Tanzania and a sample of 135 ADDOs in 3 sentinel regions. Data collection involves administering five separate questionnaires: An overview of the facility and its facilities, information about the Dispensing Outlets and the medicines dispensed to patients, information about the Stock Rooms and the medicines in stock, information about the patients diagnosed and treated, and a separate questionnaire for ADDOs.

Transparency for Development Project

The Transparency for Development (T4D) project is designed to investigate the questions of whether well-designed T/A interventions improve health outcomes and under what conditions.  The intervention will be an adaptation of the community scorecard: the community scorecard “plus” (CSC-plus). The whole project will evaluate these interventions across two phases, using a mixed methods evaluation approach. EDI are currently involved in phase 1, carrying out randomized control trials in Tanzania to evaluate the intervention effects, both on health care quality and outcomes, and on community power relations and dynamics.  We are developing and conducting, community, health facility, and household surveys, in Tanga, Tanzania.

Geographically Concentrated Multi-Level HIV Prevention in Bukoba Urban District: Outcome Evaluation of a Combination Prevention Program for ICAP  

The aim of this survey was to examine the impact of an intervention conducted by ICAP in Bukoba between 2014-2017 on the HIV prevalence, the % previously HIV diagnosed (diagnostic coverage) and the % HIV-positive on ART (ART coverage).

A Baseline survey was conducted in 2013-14 before ICAP intervention. The Endline survey was a mirror of the Baseline survey with a new sample where a joint EDI/ICAP team interview over 5,000 respondents in 2,500 households. In addition, ICAP medical staff conducted rapid HIV tests on all consenting respondents. A cohort of 300-400 respondents who were newly diagnosed as being HIV positive were then re-interviewed within two weeks of the diagnosis and again 6 months later to track their experiences.

TASAF Community Based Conditional Cash Transfer Impact Evaluation –Baseline, First and Second Follow Up Survey –

EDI were repeatedly contracted over 4 years to implement the baseline, and then first and second follo-up rounds of the TASAF Conditional Cash Transfer project.

Conditional Cash Transfers were disbursed to households assessed vulnerable by both the community and a survey instrument administered to all households in the village.  Eligible (vulnerable) households needed to abide by certain conditions, such as children’s school and clinic attendance in order to remain in the transfer programme.  The impacts are identified by a staggered introduction of the programme in 40 out of the 80 villages.

The outcome of this project provides a basis for the government to decide whether or not to scale this programme up to national level. EDI was responsible for the design and implementation of each round of the impact evaluation.

Feb 2013 – July 2014 Baseline and Endline Paralegal Survey

Evaluation of community-based legal aid programme initiated in Kagera by Mama’s Hope Organization for Legal Assistance (MHOLA). The intervention is intended to improve the delivery of legal services through 1) the provision of training paralegals at the community level and 2) providing material incentives to encourage the transfer of knowledge to all individuals in the community.  The survey involved a panel household survey (1800 households sampled from 150 clusters); a community panel survey; and, a paralegal panel survey (150 paralegals – 1 assigned per cluster).




Feb 2008 – 2009 Dissemination of the Core Welfare Indicator Questionnaire (CWIQ) results to District Councils

Design and implementation of dissemination exercises to ensure that the findings of each district level CWIQ survey were disseminated to stakeholders from district Government all the way down to the lowest administrative units (i.e. villages).  The dissemination of CWIQ data will:

-promote evidence-based policy debate;

-promote evidence-based policy formulation;

-provide tools for district level M&E; and,

-increase accountability of LGA to citizens.

The exercise involved the dissemination of the results of CWIQ to stakeholders in each district (councillors, district officials, NGOs, CBOs, Advocacy Groups, MPs, ‘interested citizens’, etc) through the facilitation of participative stakeholder workshops and the distribution of colourful, easy to read and informative posters and research briefs.

Jun 07 – 2008 Tanzania Consumption and Welfare Survey

The objective of this 4000-household year-long survey was to improve on current methods of collecting survey data on household and individual economic welfare. This was achieved through the careful design and implementation of experiments in the collection of the primary measures found in practice for both objective and subjective welfare measurement. The analytical approach was to design several alternative consumption modules with variation in terms of collection method (diary or recall), length of detail in consumption items, and length of recall period. Subjective welfare measures were anchored using innovative anchoring vignettes. Each of the 8 modules is assigned to 500 households across 7 districts in Tanzania. One module was a careful individual diary that will serve as the benchmark of consumption. The relative performance of each module is compared to the relative costs of administration. The results of this study yielded important information concerning the relative accuracy and costs of various consumption measurement designs.

Apr 06- May 07 Core Welfare Indicator Questionnaire Survey of 28 Tanzanian Districts

A team of 35 people conducted surveys in 28 districts in Tanzania. District level data was collected for about one quarter of all districts in the country. The work included listing households in 840 Enumeration Areas and organising household interviews of 12,600 households. Data entry happened through Teleform software, using scannable questionnaires.

The data collection and entry methods allowed one district to be listed in 2 weeks, interviewed in 2 weeks (sample size = 450 households) and all its questionnaires to be scanned in about 3 or 4 days. Software was written to automatically create all tables to ensure that reports come out just a few weeks after the completion of the field work. The work entailed the administration of 28 different surveys and the formulation 28 individual reports. These reports are intended for district level policy makers who, due to Tanzania’s ongoing decentralisation process, are becoming key policy makers and are increasingly in need of data to base their policies on.




Feb 05 – Sept 06 Moving out of Poverty Study – Simultaneous Mixing of Qualitative and Quantitative Research Methods

Design of an innovative strategy to simultaneously mix qualitative and quantitative research methods to understand movements out of poverty over the past 10 years in Kagera.

Using the KHDS data set (see below) an econometric prediction was made of the growth path a respondent was expected to follow between 1993 and 2004, based on what was known about him/her in 1993. Life histories were then conducted in matched sets of people who had similar predictions, but different outcomes. Thus a treatment and comparison group set-up is mimicked. The life histories were complemented with other qualitative data collection techniques such as focus group discussions and key informant interviews.

Contrary to many qualitative studies, we managed to maintain very rigid sampling procedures (using the KHDS data as our sampling frame), which will allow us to make firmer inferences. This study is part of a 16-country study to understand the determinants of poverty from the bottom up. The global effort is directed by Deepa Narayan at PREM, World Bank.

Nov 04 – Sept 05 Orphanhood and its Long-run Impact on Children

Formulation of a policy research paper using the KHDS data set (see below) to determine whether orphanhood matters in the long-run for health and education outcomes in Kagera, an area deeply affected by HIV-AIDS in Africa. The use of long-term panel data (11-13 years) allows an assessment of whether the effects of orphanhood persist into adult life. The tracking of children who have left their original area of residence also allows for more robust inferences. These two features make this a unique study.

Oct 04 – July 05 Measuring Risk Perceptions

This research started from the premise that economists study data on choices that people make and from this deduce people’s preferences and expectations. This identification process, as well as the predictions based on it, become flawed when multiple sets of preferences and expectations are consistent with the same data. The research explored one possible way forward: to measure directly people’s expectations on future states of the world. The research established the theoretical merits and practical constraints of doing so. Data on risk perceptions seems particularly relevant for understanding savings and investment behaviour in the developing world, where risk is pervasive and often posited to have significant costs. The project established a field instrument to collect risk perception data. This culminated in a paper in the Social Protection Unit Discussion Paper Series (peer-reviewed).

Jun-Aug 05 Perceptions of Time and Distance

This project was to assess the quality of data collected through household surveys as they relate to time and distance travelled. EDI organised over 500 trips in which respondents were asked to estimate time and distance to a destination (water source or school) and were subsequently requested to walk this same distance with a pedometer to measure the actual time and distance. Initial comparisons of estimated and actual times and distances shows that correlations are weak, but slightly better for time than for distance (25% and 50% correlation respectively).  Further work on whether certain socio-economic groups systematically over or underestimate will be done. If measurement error is systematic, then this could lead to erroneous inferences about the relation between access and poverty.

Mar – Sept 05 The Determinants of Schooling in Kagera Region – Sequential Quan/Qual Work

This project designed and implemented a qualitative instrument to look at the determinants of schooling in the KHDS clusters (see below). Very specifically it was geared towards understanding an empirical fact observed in the data, namely that villages with high ethno-linguistic fractionalisation performed worse in terms of schooling than those with low ethno-linguistic fractionalisation. The qualitative work was conducted to feed back into the quantitative work: to assess the likelihood of several possible scenarios to explain the empirical observation and determine strategies to test them in the data.

Jan 03 – Aug 04 Kagera Health and Development Survey: Tracking Individuals after 10+ years

EDI undertook a study into the long-run impacts of HIV/AIDS and other health shocks on the wealth dynamics of households and individuals within North West Tanzania. This study entailed the resurvey of the panel of households, communities and service providers in the Kagera Health and Development Survey (KHDS) undertaken in 1991-1994.

It involved retracing all individuals from the initial 919 households Collection of community and service provider data augments this analysis and enables the tracking of how service provision has developed in the region over the past ten years. The novel feature of this survey is its long time period (11-13 years) combined with locating even respondents who reside outside their original place of residence. Teams were sent across the whole of Tanzania and into neighbouring countries to collect data.

Apr-Nov 04 Mixed Methods Analysis of Long-term Welfare Mobility

Using qualitative research methods, including focus group discussions and life histories, to determine the primary factors relating to upward and downward income and welfare mobility. An important aspect of this research was concerned with devising novel instruments to integrate qualitative and quantitative research methods. Rather than merely triangulating the results of both methods, the aim was to develop qualitative tools that can be used as input in quantitative analysis. One of these tools was a coded life history to serve as a shock module; the other was the collection of information on risk perception in a participatory way. The papers that resulted from this research were presented at the Research and Analysis Working Group (R&AWG) to use as input in Tanzania’s Poverty Reduction Strategy Paper (PRSP) and are published in the World Bank’s Social Protection Discussion Paper Series.

Sept 03 – Sept 04 Implementation and Analysis of the CWIQ Survey in Kagera and Shinyanga Region

Conducting a 5000 household CWIQ survey in all districts in Kagera and Shinyanga regions.  Except for intensive field work management and report writing, this work involved close collaboration with the National Bureau of Statistics as well as the Local Government Authorities. The resulting reports provided detailed district level baseline data on poverty, nutrition and other welfare indicators as well as of service use and satisfaction. An important component of the project was to use recent advances in poverty mapping techniques to determine, for the first time, district level poverty rates. The findings were presented to the regional and district level authorities in formal launches, covered by all important national newspapers and television stations.

Transport Sector Project Evaluation

In 2008, the Millennium Challenge Corporation (MCC) and the Government of Tanzania (GoT) looked to reduce poverty through economic growth by making strategic investments in infrastructure under the Transportation, Energy, and Water Sector Projects.

Policy Research and its partners are conducting an economic analysis and evaluation of the transportation activities. Stakeholders have begun to recognise that regular maintenance is critical to sustaining the life of newly rehabilitated roads and that assumptions about local resources and capacity available to conduct this maintenance may need more thorough analysis to ensure that the benefits of the roads are realised in the short and long terms.

EDI responsibilities for this project are to collect data on roads users.  The scope covers one round of traffic count data (with option for second round), a vehicle intercept survey, road condition video capture, and focus group discussions along the roads that were upgraded with funding from the Tanzania compact. Data collection will occur along road segments in Rukwa, Mbeya, Ruvuma, Tanga regions and Pemba.

Tanzania Baseline Survey of Civil Servants and Water Communities

A Payment-By-Results (PbR) financing scheme supported by the Government of Tanzania and Department for International Development (DFID) provides targeted financial incentives to Local Government Authorities (LGAs) to expand rural water access in eligible districts. The objective of the PbR is to increase the availability and sustainability of functional rural water points and shift the emphasis towards long-term sustainability. This involves output-based incentives whose aim is to strengthen focus on maintaining existing water points (and rehabilitating old ones), rather than focusing only on the construction of new water points to increase coverage. To measure the impact of the PbR scheme a performance evaluation will be conducted as well as an impact evaluation of PbR’s complementary intervention. The intervention is expected to last two years in parallel with PbR’s roll-out. These evaluations form the framework for this assignment. The baseline collection consists of two surveys which EDI is responsible for implementing:

Water Community Groups Survey will consist of two parts; the Water Community Groups survey will be conducted in 1,032 villages with the Chairperson and Treasurer of the Water Committee. The Distribution Points Survey will measure the functionality of two distribution points in each village; a total of 2,064 distribution points will be surveyed.

Civil Servants Survey – Respondents will include public servants who work full time for Ministries, Regional Secretariat, Water Authorities, Agencies and Departments. In total, this survey will include around 2,380 interviews.

Bus Rapid Transit (BRT) Impact Evaluation: Dar es Salaam Transport Corridor

The Government of Tanzania is building a bus rapid transport system to improve public transportation in Dar es Salaam. Currently, public transport is provided by 5,200 privately-owned so-called daladala buses. Traffic congestion is severe. The Dar Rapid Transit (DART) system has been introduced with the aim and ambition to provide a better, more modern and more efficient public transport service to the residents of Dar es Salaam. The project is subdivided into 6 phases each including the construction of a strategic ‘corridor’ on which contracted firms exclusively run rapid transit buses, making up the Bus Rapid Transit (BRT) system.

EDI has undertaken baseline transport and traffic surveys and commuter survey data collection in Dar es Salaam to measure the impact of improved public transportation on labor market mobility the DART BRT system. Follow up data collection will be undertaken once the system is operational.

EDI conducts transport and traffic surveys and data collection projects in Dar es Salaam; for this project in particular the Baseline Data collection involved i) a travel time survey to measure commuting times from 6 points on the periphery of Dar and the CBD via bus, taxi and bajaj and ii) a survey of 1800 households sampled from 141 locations across Dar es Salaam.

Improving Rural Access in Tanzania – An Impact Evaluation

DFID is seeking to improve the accessibility of rural communities by investing in repairing “bottlenecks” along selected rural roads. This was a baseline study of 1600 households before construction takes places using 5 case study roads to assess the socio economic characteristics of those affected by the road improvements, as well as access to selected health, education and other services and agricultural markets. The study roads are located in the districts of Morogoro, Gairo, Kilombero, Bahi and Wanging’ombe. The survey also included 13 market price surveys of food and non-food items and qualitative data collection from 60 focus group discussions.

Using a realist evaluation approach, comparison of baseline and endline data will allow evaluators to explore not just what changes have occurred as a result of road improvement, but also why and how, with regards to how various contextual factors and behavioural mechanisms combine to lead to the desired outcomes. EDI is also conducting preliminary analysis of the baseline data.

Baseline Data Collection for Water Sector Impact Evaluation

Baseline Survey of MCA Tanzania’s Water Sector interventions which aim to 1. Expand the capacity of the Lower Ruvu water treatment plant serving the Dar es Salaam areas, from about 180 million litres per day (MLD) to about 270 MLD and 2. Improve water supply in Morogoro through rehabilitating a water treatment plant and improving water transfer in the existing distribution network. These interventions are expected to increase production from 18 MLD to 33 MLD.  EDI undertook a baseline survey as a part of an impact evaluation to measure the effects of the above two interventions at the utility and household level, in the treatment areas.  The survey involved a range of quantitative data collection (including listing, a 5000 household survey, follow up phone survey, service provider survey and water quality survey), as well as focus group discussions and semi-structured interviews.

Water And Sanitation Programme – Post-Intervention Data Collection And Analysis For The Impact Evaluation In Tanzania

Development and implementation of post-intervention data collection and analysis for the impact evaluation of the ‘Scaling up Sanitation and Hand-washing’ projects in Tanzania.   The follow-up household survey was implemented in the 10 districts included in the baseline study, with a sample size of 3620 households, in a total of 181 wards and 362 Sole Consultant villages. Primary participants were mothers and caretakers of children under five years old.

This post-intervention survey aimed to measure a broad range of health indicators, and intensively study the developmental, social, and economic welfare impacts of these interventions.  The objective of this evaluation is not only to assess the impact of the interventions in Tanzania, but to also compare these impacts across three other countries (with similar hygiene interventions), and two other countries (with similar sanitation interventions), and to be able to provide externally valid advice on the feasibility, effectiveness, and cost-effectiveness of these approaches in other countries.

The survey entailed the collection of biomedical data – hematocrit blood iron tests of children under five years old, anthropometric data as well as observing the ‘handwashing’ behaviour of the household members.   A Community survey was also administered in all wards.
