Prevalence, Economic Contribution, and Determinants of Trees on Farms across Sub-Saharan Africa

(Elsevier, 2017-11) Miller, Daniel C. ; Munoz-Mora, Juan Carlos ; Christiaensen, Luc

Trees on farms are often overlooked in agricultural and natural resource research and policy in Sub-Saharan Africa. This article addresses this gap using data from the Living Standards Measurement Study-Integrated Surveys on Agriculture in five countries: Ethiopia, Malawi, Nigeria, Tanzania, and Uganda. Trees on farms are widespread. On average, almost a third of rural smallholders grow trees. They account for an average of 17% of total annual gross income for tree-growing households and 6% for all rural households. Gender, land and labor endowments, and especially forest proximity and national context are key determinants of on-farm tree adoption and management. These new, national-scale insights on the prevalence, economic contribution and determinants of trees on farms in Africa lay the basis for exploring the interaction of agriculture, on-farm tree cultivation, and forestry to gain a more complete picture of the dynamics of rural livelihoods across the continent and beyond.
Variation in Quality of Primary-Care Services in Kenya, Malawi, Namibia, Rwanda, Senegal, Uganda and the United Republic of Tanzania

(World Health Organization, 2017-06) Kruk, Margaret E. ; Chukwuma, Adanna ; Mbaruku, Godfrey ; Leslie, Hannah H.

Although substantial progress has been made in reducing child and maternal deaths in the past 15 years, many women and children in low- and middle-income countries continue to die of avertable causes. To stimulate a concerted effort to narrow the gap between rich and poor countries, the United Nation’s sustainable development goals (SDGs) include new targets to reduce maternal mortality to less than 70 per 100 000 live births and to reduce deaths of children younger than five years to 25 per 1000 live births by 2030. In this paper, we analyse the variation in the quality of processes of care in health facilities in seven countries in subSaharan Africa for two primary-care services: (i) antenatal care and (ii) care of sick children, using observations of clinical care, a gold standard measure of process quality. The results will inform policy-makers about current performance and provide a starting point for a broader discussion of quality measurement in the SDG era.
Smallholders’ Land Access in Sub-Saharan Africa: A New Landscape?

(Elsevier, 2017-02) Deininger, Klaus ; Savastano, Sara ; Xia, Fang

While scholars long recognized the importance of land markets as a key driver of rural non-farm development and transformation in rural areas, evidence on the extent of their operation and the nature of participants remains limited. We use household data from 6 countries to show that there is great potential for such markets to increase productivity and equalize factor ratios. While rental markets transfer land to land-poor and labor-rich producers, their operation and thus impact may be constrained by policy restrictions. Their functioning may also be constrained by ill-defined or insecure rights that may arise from failure to fully compensate existing rights in cases of expropriation, a failure to implement more broadly land policies or to do so in a gender sensitive manner. Methodological and substantive conclusions are derived.
How Much of the Labor in African Agriculture Is Provided by Women?

(Elsevier, 2017-02) Palacios-Lopez, Amparo ; Christiaensen, Luc ; Kilic, Talip

The contribution of women to labor in African agriculture is regularly quoted in the range of 60–80%. Using individual, plot-level labor input data from nationally representative household surveys across six Sub-Saharan African countries, this study estimates the average female labor share in crop production at 40%. It is slightly above 50% in Malawi, Tanzania, and Uganda, and substantially lower in Nigeria (37%), Ethiopia (29%), and Niger (24%). There are no systematic differences across crops and activities, but female labor shares tend to be higher in households where women own a larger share of the land and when they are more educated. Controlling for the gender and knowledge profile of the respondents does not meaningfully change the predicted female labor shares. The findings question prevailing assertions regarding substantial gains in aggregate crop output as a result of increasing female agricultural productivity.
Food Price Seasonality in Africa: Measurement and Extent

(Elsevier, 2017-02) Gilbert, Christopher L. ; Christiaensen, Luc ; Kaminski, Jonathan

Everyone knows about seasonality. But what exactly do we know? This study systematically measures seasonal price gaps at 193 markets for 13 food commodities in seven African countries. It shows that the commonly used dummy variable or moving average deviation methods to estimate the seasonal gap can yield substantial upward bias. This can be partially circumvented using trigonometric and sawtooth models, which are more parsimonious. Among staple crops, seasonality is highest for maize (33 percent on average) and lowest for rice (16½ percent). This is two and a half to three times larger than in the international reference markets. Seasonality varies substantially across market places but maize is the only crop in which there are important systematic country effects. Malawi, where maize is the main staple, emerges as exhibiting the most acute seasonal differences. Reaching the Sustainable Development Goal of Zero Hunger requires renewed policy attention to seasonality in food prices and consumption.
Agricultural Intensification: The Status in Six African Countries

(Elsevier, 2017-02) Binswanger-Mkhize, Hans P. ; Savastano, Sara

Boserup and Ruthenberg (BR) provided the framework to analyze the impact of population growth and market access on the intensification of farming systems. Prior evidence in Africa is consistent with the framework. Over the past two decades, rapid population growth has put farming systems under stress, while rapid urbanization and economic growth have provided new market opportunities. New measures of agro-ecological potential and urban gravity are developed to analyze their impact on population density and market access. The descriptive and regression analyses show that the patterns of intensification across countries are only partially consistent with the BR predictions. Fallow areas have disappeared, but cropping intensities remain very low. The use of organic and chemical fertilizers is too low to maintain soil fertility. Investments in irrigation are inadequate. In light of the promising outcomes suggested by the Boserup-Ruthenberg framework, the process of intensification across these countries appears to have been weak.
AIDS at 35: A Midlife Crisis

(Taylor and Francis, 2016-12-14) Wilson, David ; Whiteside, Alan

This year marks the 35th since AIDS was first identified and the epidemic faces a ‘mid-life’ crisis. It seems to us it is time to take stock of both the successes we have meet and the challenges we face. In this editorial for the final issue of AJAR in 2016 we do this. We warned of the potential devastation AIDS would wreak across Africa, but this went unheard. We watched with dismay as colleagues and friends sickened and died, and the political leaders initially ignored what was to come. In this editorial we look at the best of times – where things went well; and the worst of times – where the challenges lie.

Does Aid for Education Educate Children? Evidence from Panel Data

(World Bank, 2008-05-30) Dreher, Axel ; Nunnenkamp, Peter ; Thiele, Rainer

Most of the aid effectiveness literature has focused on the potential growth effects of aggregate aid, with inconclusive results. Considering that donors have repeatedly stressed the multidimensionality of their objectives, a more disaggregated view on aid effectiveness is warranted. The impact of aid on education is analyzed empirically for almost 100 countries over 1970–2004. The effectiveness of sector-specific aid is assessed within the framework of social production functions. The Millennium Development Goals related to education, particularly the goal of achieving universal primary school enrollment, are considered as outcome variables. The analysis suggests that higher per capita aid for education significantly increases primary school enrollment, while increased domestic government spending on education does not. This result is robust to the method of estimation, the use of instruments to control for the endogeneity of aid, and the set of control variables included in the estimations.
Robust Multidimensional Spatial Poverty Comparisons in Ghana, Madagascar, and Uganda

(Published by Oxford University Press on behalf of the World Bank, 2006-04-06) Duclos, Jean-Yves ; Sahn, David ; Younger, Stephen D.

Spatial poverty comparisons are investigated in three African countries using multidimensional indicators of well-being. The work is analogous to the univariate stochastic dominance literature in that it seeks poverty orderings that are robust to the choice of multidimensional poverty lines and indices. In addition, the study seeks to ensure that the comparisons are robust to aggregation procedures for multiple welfare variables. In contrast to earlier work, the methodology applies equally well to what can be defined as union, intersection, and intermediate approaches to dealing with multidimensional indicators of well-being. Furthermore, unlike much of the stochastic dominance literature, this work computes the sampling distributions of the poverty estimators to perform statistical tests of the difference in poverty measures. The methods are applied to two measures of well-being, the log of household expenditures per capita and children's height-forage z scores, using data from the 1988 Ghana Living Standards Study survey, the 1993 National Household Survey in Madagascar, and the 1999 National Household Survey in Uganda. Bivariate poverty comparisons are at odds with univariate comparisons in several interesting ways. Most important, it cannot always be concluded that poverty is lower in urban areas in one region compared with that in rural areas in another, even though univariate comparisons based on household expenditures per capita almost always lead to that conclusion.
