A Cross-Country Analysis of Household Responses to Adult Mortality in Rural Sub-Saharan Africa: Implications For HIV/AIDS Mitigation And Rural Development Policies. AgEcon
Mather, David; Donovan, Cynthia; Jayne, Thomas S.; Weber, Michael T.; Chapoto, Antony; Mazhangara, Edward; Bailey, Linda; Yoo, Kyeongwon; Yamano, Takashi; Mghenyi, Elliot W..
This paper summarizes and synthesizes across the results of a set of country studies on the effects of prime-age adult mortality on rural households in Kenya, Malawi, Mozambique, Rwanda, and Zambia. Each study is based on large representative rural household surveys. These findings have implications for the design of efforts to mitigate some of the most important effects of rural adult mortality, and for key development policies and priorities.

Accelerating Africa's Structural Transformation Lessons from East Asia AgEcon
Gabre-Madhin, Eleni Z.; Johnson, Bruce F..
In most countries in sub-Saharan Africa at present, the majority of the population is engaged in agriculture, with economies in the very early stages of structural transformation - the process whereby a predominantly agrarian economy is transformed into a diversified and productive economy dominated by manufacturing and services. These countries are characterized by low levels of farm productivity, limited growth of non-farm employment and high rates of population growth. This paper focuses on the factors involved in fostering a country’s structural transformation. This process of transformation has many dimensions. Among these we emphasize interactions between four factors: increased agricultural productivity, rural industrialization, the expansion of...

African Aquaculture: A Regional Summary with Emphasis on Sub-Saharan Africa OceanDocs
Moehl, J.; Machena, C..
The African Region consists of 48 countries and five island nations, most of which are practising some form of aquaculture, often at a very low level. Over half the countries report producing less than 100 mt annually. The largest producer is Nigeria (17 700 mt) followed by Madagascar (5 100 mt) and Zambia (4 700 mt). The 1997 combined aquaculture production of the region was 40 300 mt. Aquaculture is estimated to be 95 percent small scale, with fish ponds integrated into the mosaic of agricultural activities. Mean yield is approximated as 500 kg/ha/yr, although the range is wide, from less than a hundred to more than 10 000 kg/ha/yr. A typical scenario would be a 300 m2 pond producing 15 kg a year relying on family labour and on-farm inputs. There is...

Agricultural Productivity and Policies in Sub-Saharan Africa AgEcon
Yu, Bingxin; Nin Pratt, Alejandro.
We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 45 years, looking for evidence of recent changes in growth patterns using an improved nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture between 1984 and 2006 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs. Policy interventions, including fiscal, trade and sector specific policies, appear to have played an important role in improving agriculture’s performance. Despite the improved agricultural performance, SSA...

An Updated Look at the Recovery of Agricultural Productivity in Sub-Saharan Africa AgEcon
Nin Pratt, Alejandro; Yu, Bingxin.
We analyze the evolution of Sub-Saharan Africa’s agricultural total factor productivity (TFP) over the past 40 years, looking for evidence of recent changes in growth patterns using a nonparametric Malmquist index. Our TFP estimates show a remarkable recovery in the performance of Sub-Saharan Africa’s agriculture during between 1984 and 2003 after a long period of poor performance and decline. That recovery is the consequence of improved efficiency in production resulting from changes in the output structure and an adjustment in the use of inputs, including an overall net reduction in fertilizer use but increased fertilizer use in most of the best-performing countries. Policy changes implemented by African countries between the mid-1980s and the second...

Boosting smallholder production for food security: some approaches and evidence from studies in sub-Saharan Africa AgEcon
Matshe, Innocent.
This paper uses the sustainable livelihoods framework to explore the contribution of smallholder production to food security in some sub-Saharan African countries and relates it to the South African case. Noting that many of the world’s hungry are smallholder farmers, it is clear that food insecurity is closely linked to the livelihood strategies of these farm households. As previous studies have shown, food insecurity is linked to livelihood assets, strong institutional support and a favourable external environment. In particular, the paper finds that food security depends on cereal output, budgetary support to agriculture, agricultural value added and poverty – all variables strongly linked to the sustainable livelihoods framework. Since most poor rural...

Dairy development in Ethiopia AgEcon
Ahmed, Mohamed A. M.; Ehui, Simeon K.; Assefa, Yemesrach.
Ethiopia holds large potential for dairy development due to its large livestock population, the favorable climate for improved, high-yielding animal breeds, and the relatively disease-free environment for livestock. Given the considerable potential for smallholder income and employment generation from high-value dairy products, development of the dairy sector in Ethiopia can contribute significantly to poverty alleviation and nutrition in the country. Like other sectors of the economy, the dairy sector in Ethiopia has passed through three phases or turning points, following the economic and political policy in the country. In the most recent phase, characterized by the transition towards market-oriented economy, the dairy sector appears to be moving...

Deforestation in Sub- Sahara Africa AgEcon
Diarrassouba, Malick; Boubacar, Inoussa.
According to FAO (2005) about 13 million hectares of the word’s forest are lost due to deforestation. Naoto (2006) found Africa to lead the list of countries with the highest rate of deforestation. This worrisome situation is further aggravated by the possible negative impacts of climate change due to an increase in the mean global temperature. Evidence supports that Africa is most likely to suffer the most the devastating impacts of natural calamities such as droughts and floods. This paper sought to evaluate the causes of deforestation in 27 Sub-Saharan African (SSA) countries. Our model uses annual data spanning from 1990 to 2004. Trade and urban population tend to be associated with a decline in deforestation. On the other hand, we found strong...

Determinants of Household Contributions to Collective Irrigation Management: A Case of the Doho Rice Scheme in Uganda AgEcon
Nakano, Yuko; Otsuka, Keijiro.
In order to explore the conditions of successful irrigation management, this study investigates the determinants of household contributions to the cleaning of irrigation channels and the availability of water. By using primary data collected in an irrigation scheme in Uganda, we find that household contributions to the cleaning of irrigation channels are determined by the scarcity of irrigation water, opportunity cost of labor, and private benefit associated with plot size. We also find that the availability of irrigation water increases in the tertiary irrigation area where the coefficient of variation of plot size is large.

Energy Access Scenarios to 2030 for the Power Sector in Sub-Saharan Africa AgEcon
Bazilian, Morgan; Nussbaumer, Patrick; Rogner, Hans-Holger; Brew-Hammond, Abeeku; Foster, Vivien; Kammen, Daniel M.; Pachauri, Shonali; Eric, Williams; Howells, Mark; Niyongabo, Philippe; Musaba, Lawrence; O Gallachoir, Brian; Radka, Mark.
In order to reach a goal of universal access to modern energy services in Africa by 2030, consideration of various electricity sector pathways is required to help inform policy-makers and investors, and help guide power system design. To that end, and building on existing tools and analysis, we present several ‘high-level’, transparent, and economy-wide scenarios for the sub-Saharan African power sector to 2030. We construct these simple scenarios against the backdrop of historical trends and various interpretations of universal access. They are designed to provide the international community with an indication of the overall scale of the effort required. We find that most existing projections, using typical long-term forecasting methods for power...

ENVIRONMENTAL AND ECONOMIC IMPACTS OF SOIL EROSION AND FERTILITY MINING IN NORTHERN TANZANIA AgEcon
Nkonya, Ephraim M.; Barkley, Andrew P.; Hamilton, Stephen F.; Bernardo, Daniel J..
This paper develops a soil conservation model that is relevant to smallholder farmers who apply little or no fertilizer. Empirical results drawn from northern Tanzania imply that, ignoring fertility mining problem in model specification leads to overestimation of profits for farms that apply little or no fertilizer. The model also shows that, the impact of output price on soil conservation efforts depends on the curvature of the soil erosion function.

Ethnomedicinal plants used for snakebite treatments in Ethiopia: a comprehensive overview J. Venom. Anim. Toxins incl. Trop. Dis.
Yirgu,Abraham; Chippaux,Jean-Philippe.
Abstract Traditional medicine plays an important role in the daily lives of people living in rural parts of Ethiopia. Despite the fact that Ethiopia has a long history of using traditional medicinal plants as an alternative medicine source, there is no checklist compiling these plants used for snakebite treatment. This review collected and compiled available knowledge on and practical usage of such plants in the country. A literature review on medicinal plants used to treat snakebites was conducted from 67 journal articles, PhD dissertation and MSc theses available online. Data that summarize scientific and folk names, administration methods, plant portion used for treatment and method of preparation of recipes were organized and analyzed based on citation...

Food Reserve Stocks and Critical Food Shortages - a Proposal Based on the Needs of Sub-Saharan Africa AgEcon
Lind, Kim Martin.
This working paper examines the food security policy, where food security means ensuring an adequate supply of food for hungry people. In particular, the recommendations of FAO are being used as a measuring rod against which food security policies are assessed. By means of FAO's database a statistical analysis of all Sub-Saharan Africa countries with respect to measuring the incidence and severity of critical food shortages are carried out. Stock policies seem to have been the answer when issues of ensuring adequate supplies have surfaced. In the paper, an estimate of the costs of keeping stocks is provided, and the costs are quite staggering. Based on the statistical analysis an estimate of the number and volume of acute food shortages per year in...

Generating Plausible Crop Distribution and Performance Maps for Sub-Saharan Africa Using a Spatially Disaggregated Data Fusion and Optimization Approach AgEcon
You, Liangzhi; Wood, Stanley; Wood-Sichra, Ulrike.
Agricultural production statistics reported at country or sub-national geopolitical scales are used in a wide range of economic analyses, and spatially explicit (geo-referenced) production data are increasingly needed to support improved approaches to the planning and implementation of agricultural development. However, it is extremely challenging to compile and maintain collections of sub-national crop production data, particularly for poorer regions of the world. Large gaps exist in our knowledge of the current geographic distribution and spatial patterns of crop performance, and these gaps are unlikely to be filled in the near future. Regardless, the spatial scale of many sub-national statistical reporting units remains too coarse to capture the...

Human Milk: An Invisible Food Resource AgEcon
Hatloy, Anne; Oshaug, Arne.
Human milk is a food that meets all conditions for an infant's nutrition security and is the most important food for more than 10 percent of the population in Sub-Saharan Africa (children less than three years of age). Statistics on production of human milk at local and national levels are lacking for Africa. In this paper, the quantity of human milk production in Mali, Senegal, Nigeria, and Zimbabwe is estimated. The annual production in the urban and rural areas in a county in Mali is estimated at 13 and 17 kilograms per capita, respectively. National annual median production is estimated to be between 144,000 (Mali) and 1.3 million metric tons (Nigeria), and production per capita between 8 (Zimbabwe) and 15 kilograms per year (Mali). In Sub-Saharan...

Impact of human schistosomiasis in sub-Saharan Africa BJID
Adenowo,Abiola Fatimah; Oyinloye,Babatunji Emmanuel; Ogunyinka,Bolajoko Idiat; Kappo,Abidemi Paul.
Schistosomiasis, a neglected tropical disease of poverty ranks second among the most widespread parasitic disease in various nations in sub-Saharan Africa. Neglected tropical diseases are causes of about 534,000 deaths annually in sub-Saharan Africa and an estimated 57 million disability-adjusted life-years are lost annually due to the neglected tropical diseases. The neglected tropical diseases exert great health, social and financial burden on economies of households and governments. Schistosomiasis has profound negative effects on child development, outcome of pregnancy, and agricultural productivity, thus a key reason why the "bottom 500 million" inhabitants of sub-Saharan Africa continue to live in poverty. In 2008, 17.5 million people were treated...

Incentives for Fertilizer Use in Sub-Saharan Africa: A Review of Empirical Evidence on Fertilizer Response and Profitability AgEcon
Yanggen, David; Kelly, Valerie A.; Reardon, Thomas; Naseem, Anwar.
This research addresses two questions: Why is fertilizer not yet fulfilling its potential as a major stimulus to agricultural productivity in SSA? What can be done to improve the situation? Our answers are based on an extensive review of fertilizer response, profitability, and policy literature as well as some analysis of crop budgets and aggregate national statistics on fertilizer consumption. Much of the debate about fertilizer use in SSA focuses on two issues: whether the profit incentive is adequate and, if so, whether farmers have the capacity to access and use it.

Income Growth and Gender Bias in Childhood Mortality in Developing Countries AgEcon
Ueyama, Mika.
With poverty studies having shifted their focus from household poverty to individual poverty, a number of studies have started to examine intrahousehold resource allocation, especially gender bias within the household as potential causes of poverty. The literature has highlighted the existence of gender inequalities in South Asia, attributed to strong preferences for male offspring stemming from cultural and traditional customs. Only a few studies focused on the regional difference in the extent of gender bias and its response to income growth. To fill a void in previous studies, this study analyzes regional differences in gender discrimination, taking into account time-series variations. Furthermore, we test whether economic factors are responsible for...
