    Abstract: High resolution datasets of population density which accurately map sparsely distributed human populations do not exist at a global scale. Typically, population data is obtained using censuses and statistical modeling. More recently, methods using remotely-sensed data have emerged, capable of effectively identifying urbanized areas. Obtaining high accuracy in estimation of population distribution in rural areas remains a very challenging task due to the simultaneous requirements of sufficient sensitivity and resolution to detect very sparse populations through remote sensing as well as reliable performance at a global scale. Here, the authors present a computer vision method based on machine learning to create population maps from satellite imagery at a global scale, with a spatial sensitivity corresponding to individual buildings and suitable for global deployment

    Parallel Title: Erscheint auch als Ingelaere, Bert Why Secondary Towns Can Be Important for Poverty Reduction - A Migrant's Perspective
    Abstract: This paper develops the concept of "action space" as the range of possible destinations to which a migrant can realistically move at a given point in time and, intimately linked to this, the set of possible livelihoods at destination. It shows how this space expands and contracts over time through "cumulative causation." Such a dynamic framework allows for appreciating the role of secondary towns in rural-urban migration and poverty reduction. Secondary towns occupy a unique middle ground between semi-subsistence agriculture and the capitalistic city, between what is close by and familiar and what is much further away and unknown. By opening the horizons of the (poorer) rural population and facilitating navigation of the nonfarm economy, secondary towns allow a broader base of the poor population to become physically, economically, and socially mobile. Secondary towns therefore have great potential as vehicles for inclusive growth and poverty reduction in urbanizing developing countries. These are the insights emerging from the in-depth life history accounts of 75 purposively selected rural-urban migrants from rural Kagera, in Tanzania

    Parallel Title: Erscheint auch als Christiaensen, Luc Where to Create Jobs to Reduce Poverty: Cities Or Towns?
    Abstract: Should public investment be targeted to big cities or to small towns, if the objective is to minimize national poverty? To answer this policy question, this paper extends the basic Todaro-type model of rural-urban migration to the case of migration from rural areas to two potential destinations, secondary town and big city. The analysis first derives the labor income, migration cost and poverty line conditions under which a poverty gradient from rural to town to city will exist as an equilibrium phenomenon. Then sufficient statistics are developed for the policy decisions based on these parameters. The empirical remit of the model is illustrated with long-running panel data from Kagera, Tanzania. Further, the paper shows that the structure of the sufficient statistics is maintained in the case where the model is generalized to introduce heterogeneous workers and jobs

    Parallel Title: Erscheint auch als Christiaensen, Luc Agriculture in Africa - Telling Myths from Facts: A Synthesis
    Abstract: Stylized facts drive research agendas and policy debates. Yet robust stylized facts are hard to come by, and when available, often outdated. In a special issue of Food Policy, 12 papers revisit conventional wisdom on African agriculture and its farmers' livelihoods using nationally representative surveys from the Living Standards Measurement Study-Integrated Surveys on Agriculture Initiative in six African countries. At times, the findings simply confirm the common understanding of the topic. But the studies also throw up several surprises, redirecting some policy debates while fine-tuning others. Overall, the project calls for more attention to checking and updating the common wisdom. This requires nationally representative data, and sufficient incentives among researchers and policy makers alike. Without well-grounded stylized facts, they can easily be profoundly misguided

    Abstract: Stylized facts set agendas and shape debates. In rapidly changing and data scarce environments, they also risk being ill-informed, outdated and misleading. So, following higher food prices since the 2008 world food crisis, robust economic growth and rapid urbanization, and climatic change, is conventional wisdom about African agriculture and rural livelihoods still accurate? Or is it more akin to myth than fact? The essays in "Agriculture in Africa" Telling Myths from Facts? aim to set the record straight. They exploit newly gathered, nationally representative, geo-referenced information at the household and plot level, from six African countries. In these new Living Standard Measurement Study-Integrated Surveys on Agriculture, every aspect of farming and non-farming life is queried-from the plots farmers cultivate, the crops they grow, the harvest that is achieved, and the inputs they use, to all the other sources of income they rely on and the risks they face. Together the surveys cover more than 40 percent of the Sub-Saharan African population. In all, sixteen conventional wisdoms are examined, relating to four themes: the extent of farmer's engagement in input, factor and product markets; the role of off-farm activities; the technology and farming systems used; and the risk environment farmers face. Some striking surprises, in true myth-busting fashion, emerge. And a number of new issues are also thrown up. The studies bring a more refined, empirically grounded understanding of the complex reality of African agriculture. They also confirm that investing in regular, nationally representative data collection yields high social returns

    Parallel Title: Erscheint auch als Montalvao, Joao Soft Skills for Hard Constraints: Evidence from High-Achieving Female Farmers
    Abstract: This paper documents the positive link between the noncognitive skills of women farmers and the adoption of a cash crop. The context is Malawi, one of the poorest countries in the world, where the majority of rural households practice subsistence farming. The analysis finds that a one standard deviation increase in noncognitive ability related to perseverance is associated with a five percentage point (or 33 percent) increase in the probability of adoption of the main cash crop. This link is not explained by differences across women in education and cognitive skills. It is also not explained by the fact that women with higher noncognitive ability tend to be married to husbands of higher noncognitive ability and education. The effect of female noncognitive skills on adoption is concentrated in patrilocal communities, where women face greater adversity and thus where it would be expected that the returns to such skills would be highest. One main channel through which noncognitive skills seem to work is through the use of productive inputs, including higher levels of labor, fertilizer, and agricultural advice services

    Parallel Title: Erscheint auch als Gourlay, Sydney Could the Debate Be Over? Errors in Farmer-Reported Production and Their Implications for the Inverse Scale-Productivity Relationship in Uganda
    Abstract: Based on a two-round household panel survey conducted in Eastern Uganda, this study shows that the analysis of the inverse scale-productivity relationship is highly sensitive to how plot-level maize production, hence yield (production divided by GPS-based plot area), is measured. Although farmer-reported production-based plot-level maize yield regressions consistently lend support to the inverse scale-productivity relationship, the comparable regressions estimated with maize yields based on sub-plot crop cutting, full-plot crop cutting, and remote sensing point toward constant returns to scale, at the mean as well as throughout the distributions of objective measures of maize yield. In deriving the much-debated coefficient for GPS-based plot area, the maize yield regressions control for objective measures of soil fertility, maize genetic heterogeneity, and edge effects at the plot level; a rich set of plot, household, and plot manager attributes; as well as time-invariant household- and parcel-level unobserved heterogeneity in select specifications that exploit the panel nature of the data. The core finding is driven by persistent overestimation of farmer-reported maize production and yield vis-a-vis their crop cutting-based counterparts, particularly in the lower half of the plot area distribution. Although the results contribute to a larger, and renewed, body of literature questioning the inverse scale-productivity relationship based on omitted explanatory variables or alternative formulations of the agricultural productivity measure, the paper is among the first documenting how the inverse relationship could be a statistical artifact, driven by errors in farmer-reported survey data on crop production

    Parallel Title: Erscheint auch als McCarthy, Nancy Shelter from the Storm? Household-Level Impacts of, and Responses to, the 2015 Floods in Malawi
    Abstract: As extreme weather events intensify due to climate change, it becomes ever more critical to understand how vulnerable households are to these events and the mechanisms households can rely on to minimize losses effectively. This paper analyzes the impacts of the floods that occurred during the 2014/15 growing season in Malawi, using a two-period panel data set. The results show that while yields were dramatically lower for households severely affected by the floods, drops in food consumption expenditures and calories per capita were less dramatic. However, dietary quality, as captured by the food consumption score, was significantly lower for flood-affected households. Although access to social safety nets increased food consumption outcomes, particularly for those in moderately-affected areas, the proportion of households with access to certain safety net programs was lower in 2015 compared with 2013. The latter finding suggests that linking these programs more closely to disaster relief efforts could substantially improve welfare outcomes during and after a natural disaster. Finally, risk-coping strategies, including financial account ownership, access to off-farm income sources, and adult children living away from home, were generally ineffective in mitigating the negative impacts of the floods

    Parallel Title: Erscheint auch als Kilic, Talip Mission Impossible? Exploring the Promise of Multiple Imputation for Predicting Missing GPS-Based Land Area Measures in Household Surveys
    Abstract: Research has provided robust evidence for the use of GPS technology to be the scalable gold standard in land area measurement in household surveys. Nonetheless, facing budget constraints, survey agencies often seek to measure with GPS only plots within a given radius of dwelling locations. Subsequently, it is common for significant shares of plots not to be measured, and research has highlighted the selection biases resulting from using incomplete data. This study relies on nationally-representative, multi-topic household survey data from Malawi and Ethiopia that exhibit near-negligible missingness in GPS-based plot areas, and validates the accuracy of a multiple imputation model for predicting missing GPS-based plot areas in household surveys. The analysis (i) randomly creates missingness among plots beyond two operationally relevant distance measures from the dwelling locations; (ii) conducts multiple imputation under each distance scenario for each artificially created data set; and (iii) compares the distributions of the imputed plot-level outcomes, namely, area and agricultural productivity, with the known distributions. In Malawi, multiple imputation can produce imputed yields that are statistically undistinguishable from the true distributions with up to 82 percent missingness in plot areas that are further than 1 kilometer from the dwelling location. The comparable figure in Ethiopia is 56 percent. These rates correspond to overall rates of missingness of 23 percent in Malawi and 13 percent in Ethiopia. The study highlights the promise of multiple imputation for reliably predicting missing GPS-based plot areas, and provides recommendations for optimizing fieldwork activities to capture the minimum required data

    Parallel Title: Erscheint auch als McCarthy, Nancy Stronger Together: Intra-Household Cooperation and Household Welfare in Malawi
    Abstract: It has long been recognized that household decision-making may not result in outcomes consistent with the unitary household model. Within the collective bargaining framework, consumption decisions would be driven by the spouse with greater bargaining power, while the outcomes would still be Pareto efficient. Within the non-cooperative framework, households would not achieve Pareto efficient outcomes, and under the simplest representation, bargaining power would not affect consumption decisions. This paper develops a model that allows consumption patterns and labor supply to be affected by both bargaining power and non-cooperation. The model highlights the potential gains from improving bargaining power versus increasing cooperation between spouses, and presents conditions under which relatively large gains would be expected from moving to more equitable bargaining power versus achieving intra-household cooperation. The model's predictions are in turn tested using a unique panel data set on married couples in rural Malawi. The analysis shows that, relative to increasing wives' bargaining power, improving cooperation between spouses would exert larger and statistically significant positive impacts on total household income and consumption expenditures per capita, as well as the share of household consumption devoted to public goods. Supported also by cross-country qualitative research, the results suggest that household public goods are relatively important to both women and men in rural Malawi, husbands' capacity to control wives' incomes is relatively limited, and development programs that promote intra-household cooperation could lead to greater gains in income and household public goods provision compared with interventions focusing exclusively on women's empowerment

    Abstract: L'idee que l'on se fait de l'Afrique a radicalement change. Encore considere comme le continent des guerres, des famines et de la pauvrete chronique a la fin des annees 90, le continent africain est maintenant evoque sous l'angle de l'Afrique qui monte et du XXIe siecle africain. Deux decennies de croissance economique sans precedent devaient en principe ameliorer sensiblement le bien-etre des populations africaines. Il est toutefois difficile de dire si c'est effectivement le cas en raison de la mediocre qualite des donnees, de la nature du processus de croissance (s'agissant notamment du role des ressources naturelles), des conflits qui sevissent dans une partie la region et de la forte expansion demographique. Poverty in a Rising Africa decrit les problemes de donnees et analyse systematiquement les informations disponibles sur la pauvrete et les inegalites dans une perspective tant monetaire que non monetaire. Le premier chapitre evalue la disponibilite et la qualite des donnees necessaires pour cerner la pauvrete monetaire, examine les mecanismes de gouvernance et les processus politiques qui sous-tendent la production statistique et propose quelques methodes pour combler le deficit de donnees. Le chapitre 2 evalue la robustesse des estimations sur la pauvrete en Afrique et brosse a grands traits le profil de ce fleau. Selon les auteurs, la reduction de la pauvrete en Afrique est peut-etre legerement superieure a ce que les estimations traditionnelles portent a croire. Pour autant, meme les estimations les plus optimistes indiquent que davantage de personnes vivaient dans la pauvrete en 2012 qu'en 1990. Le troisieme chapitre considere la pauvrete dans une perspective elargie en prenant en compte les dimensions non monetaires du bien-etre, telles que l'education, la sante et la liberte, en utilisant la methode d'Amartya Sen (1985) axee sur les notions de capabilities et de functionings. Des progres ont certes ete accomplis dans plusieurs de ces domaines, mais les niveaux de resultats restent obstinement bas. Enfin, le chapitre 4 examine les donnees relatives aux inegalites en Afrique en analysant non seulement les types d'inegalites monetaires, mais aussi d'autres aspects tels que l'inegalite des chances, la mobilite intergenerationnelle dans le travail et l'education et l'extreme richesse

    Abstract: Assets generate and help diversify income, provide collateral to access credit, alleviate liquidity constraints in the face of shocks, and are key inputs into empowerment. Despite the importance of individual-level data on asset ownership and control, and that most assets are owned by individuals, solely or jointly, it is typical for the micro data on asset ownership to be collected at the household level, often from only one respondent per household. Even when the data are collected at the individual level, with identification of reported or documented owners of a given asset within the household, the information is still often solicited from a single respondent. Further, the identification of owners is seldom paired with the identification of individuals who hold various rights to assets, limiting understanding of the interrelationships among ownership and rights, and whether these relationships vary across individuals. Through a review of the existing approaches to data collection and the relevant literature on survey methodology, this paper presents an overview of the current best practices for collecting individual-level data on the ownership and control of assets in household and farm surveys. The paper provides recommendations in three areas: (1) respondent selection; (2) definition and measurement of assess to and ownership and control of assets; and (3) measurement of the quantity, value, and quality of assets. Open methodological questions that can be answered through analysis of existing data or the collection and analysis of new data are identified for future research

    Abstract: From 2000 to 2014, per capita gross domestic product in Sub-Saharan Africa increased by almost 35 percent in real terms, doubling in some countries. Such progress happened while agricultural productivity growth remained low in the aggregate, despite some bright spots, and poverty reduction was steady but discouragingly slow. This paper argues that ending extreme poverty will require structural change in agriculture, and in rural African economies more broadly. Drawing on a range of recent research, the paper outlines broad priority areas for policy actions to accelerate productivity and initiate structural change in the agriculture sector and the rural nonfarm economy

    Abstract: After a decade of crisis and stellar economic growth over the past five years, Cote d'Ivoire has now set its sight on becoming an emerging economy. Improving prospects for productive employment will be essential for socially sustainable growth and poverty reduction. The "Cote d'Ivoire Jobs Diagnostic: Employment, Productivity, and Inclusion for Poverty Reduction" report provides a comprehensive and multi-sectoral empirical analysis of employment challenges and opportunities to inform strategies and policy actions in Cote d'Ivoire. The report aims to expand policy discussions on employment from a focus on the number of jobs and unemployment to a broader attention on the quality, productivity and inclusiveness of jobs. It makes the case for a jobs strategy with a sharper poverty lens that would focus on raising labor productivity in agriculture and informal off-farm employment to foster structural transformation, while, in parallel, pursuing longer-term goals of expanding the thin formal sector
