    Parallel Title: Zezza, Alberto Milking the Data
    Abstract: Milk is an important source of cash and nutrients for many households in developing countries. Yet, the understanding of the role of dairy production in livelihoods and nutritional outcomes is hindered by the lack of decent quality household survey data. Data on milk off-take for human consumption are difficult to collect in household surveys for several reasons that make accurate recall challenging for the respondent (continuous production and seasonality, among others). As a result, the quantification and valuation of milk off-take is particularly difficult in household surveys, introducing possibly severe biases in the computation of full household incomes and farm sales, as well as in the estimation of the contribution of livestock (specifically dairy) production in agricultural value added and the livelihoods of rural households. This paper presents results from a validation exercise implemented in Niger, where alternative survey instruments based on recall methods were administered to randomly selected households and compared with a 12-month system of physical monitoring and recording of milk production. The results of the exercise show that reasonably accurate estimates via recall methods are possible and provide a clear ranking of questionnaire design options that can inform future survey operations

    Parallel Title: Erscheint auch als Print Version: Kanyanda, Shelton Acceptance of COVID-19 Vaccines in Sub-Saharan Africa: Evidence from Six National Phone Surveys
    Keywords: COVID-19 Vaccination ; Disease Control and Prevention ; Health, Nutrition and Population ; Household Survey ; Immunizations ; Public Health ; Public Health Promotion
    Abstract: Recent debates surrounding the lagging COVID-19 vaccination campaigns in low-income countries center around vaccine supply and financing. Yet, relatively little is known about attitudes toward COVID-19 vaccines in these countries and in Africa in particular. This paper provides cross-country comparable estimates of the willingness to accept a COVID-19 vaccine in six Sub-Saharan African countries. It uses data from six national high-frequency phone surveys in countries representing 38 percent of the Sub-Saharan African population (Burkina Faso, Ethiopia, Malawi, Mali, Nigeria, and Uganda). Samples were drawn from large, nationally representative sampling frames providing a rich set of demographic and socioeconomic characteristics which are used to disaggregate the analysis. The findings show acceptance rates to be generally high, with at least four in five people willing to be vaccinated in all but one country. Vaccine acceptance ranges from nearly universal in Ethiopia (97.9 percent) to below what would likely be required for herd immunity in Mali (64.5 percent). Safety concerns about the vaccine in general and its side effects emerge as the primary reservations toward a COVID-19 vaccine across countries. These findings suggest that limited supply, not inadequate demand, likely presents the key bottleneck to reaching high COVID-19 vaccine coverage in Sub-Saharan Africa

    Parallel Title: Erscheint auch als Gourlay, Sydney Measuring Land Tenure at the Individual Level: Lessons from Methodological Research in Armenia
    Keywords: Access To Finance ; Female Land Tenure Inequity ; Finance and Development ; Household Surveys ; Individual Land Rights ; Land Ownership ; Land Tenure ; Resilience To Economic Shock ; Rural Development ; Rural Land Policies for Poverty Reduction ; SDGS ; Sustainable Development Goals ; Finance and Financial Sector Development
    Abstract: Evidence indicates that land rights are strongly associated with several indicators of well-being and development outcomes, including access to credit, resilience to shocks, productivity, and bargaining power. Accurately capturing gender differences in land rights is thus critical for development policy, prompting the need to shift from household-level land rights data collection to collecting more and better individual-level data on land rights. The importance of individual land rights has been recognized in the Sustainable Development Goals (SDG) agenda, with the inclusion of two key indicators on land rights-SDG indicators 1.4.2 and 5.a.1. Although clear guidance exists for computing and monitoring these, the choice of data collection methods may influence the resulting indicators and the understanding of the underlying land rights. Specifically, research has shown that the use of proxy respondents in the collection of data on assets, including land, results in a biased understanding of men's and women's holdings vis-a-vis self-reporting. This paper uses data from a methodological experiment in Armenia to assess the implications of survey design-Snamely, respondent strategy and the level of disaggregation of land data-Son the measurement of individual land rights and SDG indicator monitoring. The findings suggest that in the context of Armenia, the measurement of SDG 5.a.1 and 1.4.2 (a) is robust to respondent approach and data disaggregation level, driven largely by the high rates of documentation. Meanwhile, land rights that are less objective, such as the right to bequeath and perception of tenure security, are sensitive to these survey design choices

    Keywords: Access To Vaccine ; COVID-19 ; Immunizations ; Intrahousehold Power Relations ; Public Health Promotion ; Vaccination ; Vaccine Acceptance ; Vaccine Hesitancy ; Health, Nutrition and Population
    Abstract: As COVID-19 vaccines have become more widely available in Sub-Saharan Africa, vaccination campaigns in the region have struggled to pick up pace and trail the rest of the world. This paper presents new evidence on vaccine hesitancy, uptake, last-mile delivery barriers, and potential strategies to reach those who remain unvaccinated. The data come from high-frequency phone surveys in five countries in East and West Africa (Burkina Faso, Kenya, Malawi, Nigeria, and Tanzania). The surveys were conducted by countries' national statistical agencies, have national scope, are cross-country comparable, and draw their samples from nationally representative sampling frames. The findings show that across the study countries, a majority is willing to get vaccinated. Still, vaccine hesitancy is non-negligible among those pending vaccination. Concerns about side effects of the vaccine are the primary reason for hesitancy. At the same time, many who are willing to get vaccinated are deterred by a lack of easy access to vaccines at the local level. Radio broadcasts have widespread reach and medical professionals have good rapport among the unvaccinated population. Furthermore, social ties and perceptions as well as intrahousehold power relations matter for vaccine take-up. Based on the findings, the paper elaborates policy options to boost vaccination campaigns in Sub-Saharan Africa

    Parallel Title: Erscheint auch als Zezza, Alberto From Necessity to Opportunity: Lessons for Integrating Phone and in-Person Data Collection for Agricultural Statistics in a Post-Pandemic World
    Keywords: Agricultural Statistics ; COVID-19 Impact Data ; COVID-19 Lock-Down ; Digital Divide ; Gender ; Gender Monitoring and Evaluation ; Health Monitoring and Evaluation ; Health, Nutrition and Population ; Household Survey ; Information and Communication Technologies ; Living Standards ; Phone Survey ; Poverty Monitoring and Analysis ; Rural Population ; Rural Survey Technique ; Survey Methods
    Abstract: The COVID-19 pandemic has disrupted survey and data systems globally and especially in low- and middle-income countries. Lockdowns necessitated remote data collection as demand for data on the impacts of the pandemic surged. Phone surveys started being implemented at a national scale in many places that previously had limited experience with them. As in-person data collection resumes, the experience gained provides the grounds to reflect on how phone surveys may be incorporated into survey and data systems in low- and middle-income countries. This includes agricultural and rural surveys supported by international survey programs such as the World Bank's Living Standards Measurement Study-Integrated Surveys on Agriculture, the Food and Agriculture Organization's AGRISurvey, or the 50*2030 Initiative. Reviewing evidence and experiences from before and during the pandemic, the paper analyzes and provides guidance on the scope of and considerations for using phone surveys for agricultural data collection. It addresses the domains of sampling and representativeness, post-survey adjustments, questionnaire design, respondent selection and behavior, interviewer effects, as well as cost considerations, all with an emphasis on the particularities of agricultural and rural surveys. Ultimately, the integration of phone interviews with in-person data collection offers a promising opportunity to leverage the benefits of phone surveys while addressing their limitations, including the depth of content constraints and potential coverage biases, which are especially challenging for agricultural and rural populations in low- and middle-income countries

    Parallel Title: Erscheint auch als Print Version: Carletto, Calogero Agricultural Data Collection to Minimize Measurement Error and Maximize Coverage
    Keywords: Agricultural Knowledge and Information Systems ; Agricultural Research ; Agricultural Sector Economics ; Agriculture ; Data Collection ; Survey Design
    Abstract: Advances in agricultural data production provide ever-increasing opportunities for pushing the research frontier in agricultural economics and designing better agricultural policy. As new technologies present opportunities to create new and integrated data sources, researchers face trade-offs in survey design that may reduce measurement error or increase coverage. This paper first reviews the econometric and survey methodology literatures that focus on the sources of measurement error and coverage bias in agricultural data collection. Second, it provides examples of how agricultural data structure affects testable empirical models. Finally, it reviews the challenges and opportunities offered by technological innovation to meet old and new data demands and address key empirical questions, focusing on the scalable data innovations of greatest potential impact for empirical methods and research

    Abstract: This sourcebook summarizes the outputs and lessons of the Livestock in Africa: improving data for better policies project. It aims to present the challenges facing professionals collecting and analyzing livestock data and statistics and possible solutions. While the Sourcebook does not address all conceivable issues related to enhancing livestock data and underlining statistical issues, it does represent a unique document for a number of reasons. To begin with, it is possibly the first document which specifically addresses the broad complexity of livestock data collection, taking into consideration the unique characteristics of the sector. Indeed, in most cases livestock data are dealt with, if ever, within the context of major agricultural initiatives. Second, the sourcebook is a joint product of users and suppliers of livestock data, with its overarching objective being to respond to the information needs of data users, and primarily the Ministries responsible for livestock in African countries and the National Statistical Authorities. Finally, the sourcebook represents a unique experiment of inter-institutional collaboration, which jointly places the World Bank, the FAO Animal Production and Health Division, the ILRI and the Africa Union, Interafrican Bureau for Animal Resources as well as national governments in Niger, Tanzania and Uganda at the forefront of data and statistical innovation for evidence-based livestock sector policies and investments. This sourcebook represents a first step towards a demand-driven and sustainable approach to enhance the livestock information available to decision makers. It is hoped it will provide a useable framework for significantly improving the quantity and quality of livestock data and statistics available to the public and private sector, and also increase the efficacy of investments that country governments and the international community allocate to generate information for livestock sector policies and investments

    Parallel Title: Erscheint auch als Carletto, Calogero Cheaper, Faster, and More Than Good Enough: Is GPS the New Gold Standard in Land Area Measurement?
    Abstract: In rural societies of low- and middle-income countries, land is a major measure of wealth, a critical input in agricultural production, and a key variable for assessing agricultural performance and productivity. In the absence of cadastral information to refer to, measures of land plots have historically been taken with one of two approaches: traversing (accurate, but cumbersome), and farmers' self-report (cheap, but marred by measurement error). Recently, the advent of cheap handheld GPS devices has held promise for balancing cost and precision. Guided by purposely collected primary data from Ethiopia, Nigeria, and Tanzania (Zanzibar), and with consideration for practical household survey implementation, the paper assesses the nature and magnitude of measurement error under different measurement methods and proposes a set of recommendations for plot area measurement. The results largely point to the support of GPS measurement, with simultaneous collection of farmer self-reported areas
