The agro-ecosystems of semi-arid and dry sub-humid SSA are inherently dynamic. At this point in time they are also experiencing a series of complex social&amp;#8211;ecological changes that make their future even more uncertain. To ensure that development investments made today in the small-scale farming systems that dominate these regions make sense also in a long-term perspective they should benefit the local communities over a range of potential futures. We applied a participatory scenario planning approach to a smallholder farming community in semi-arid Tanzania, exploring four alternative development trajectories for the area, to increase the robustness of current investments in small-scale water system technologies. We found that water system...

Small Reservoirs, Landscape Changes and Water Quality in Sub-SaharanWest Africa
Provedor de dados: 5
Autores: Cecchi, Philippe; Forkuor, Gerald; Cofie, Olufunke; Lalanne, Franck; Poussin, Jean-christophe; Jamin, Jean-yves.
Small reservoirs (SRs) are essential water storage infrastructures for rural populations of Sub-SaharanWest Africa. In recent years, rapid population increase has resulted in unprecedented land use and land cover (LULC) changes. Our study documents the impacts of such changes on the water quality of SRs in Burkina Faso. Multi-temporal Landsat images were analyzed to determine LULC evolutions at various scales between 2002 and 2014. Population densities were calculated from downloaded 2014 population data. In situ water samples collected in 2004/5 and 2014 from selected SRs were analyzed for Suspended Particulate Matter (SPM) loads, an integrative proxy for water quality. The expansion of crop and artificial areas at the expense of natural covers controlled...

Ethnomedicinal plants used for snakebite treatments in Ethiopia: a comprehensive overview
Provedor de dados: 80
Autores: 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...

We report herein the case of 19-year-old female farmer who suffered a double snakebite on the right foot. After an unsuccessful traditional treatment, she consulted a health center, 48 hours after the bite. Upon arrival at the hospital, she showed signs of severe damage, including hemorrhagic syndrome, extensive gangrene of the bitten limb and severe acute renal failure. Due to financial constraints, neither antivenom nor the scheduled amputation was performed. After 35 days of hospitalization, she returned home, against the advice of medical personnel. Our case summarizes the daily challenges of patients and practitioners that suffer snakebite envenomation in Bobo-Dioulasso, western Burkina Faso.

The WHO strategy for prevention and control of snakebite envenoming: a sub-Saharan Africa plan
Provedor de dados: 80
Autores: Chippaux,Jean-Philippe; Massougbodji,Achille; Habib,Abdulrazaq G.
Abstract Snakebite is a critical public health issue in tropical countries, particularly in Africa, where 20% of snakebites globally occur. In 2017, the WHO added snakebite envenoming to the category A of neglected tropical diseases. In 2019, thanks to broad institutional and international NGO support, including strong mobilization of African experts and governments, WHO launched a strategy for prevention and control of snakebite envenoming with more ambitious goals. In sub-Saharan Africa, accessibility of antivenoms and symptomatic, adjuvant or replacement therapy is a priority. Several antivenoms are available but their evaluation has not been properly carried out and they remain expensive. To date, there are no manufacturers of antivenom in sub-Saharan...

The Pentatomoidea (Hemiptera: Heteroptera) of Sub-Saharan Africa : a database
Provedor de dados: 16
Autores: Robertson, I.A.D.
Introduction    The purpose of this database is to list all the taxonomic publications on this Superfamily in Sub-Saharan Africa until the year 2000. It is also intended to give an indication of the kind of information contained in each paper. No attempt has been made to change or criticise what authors have written. Instead the intent has been to record accurately the published material.    This database does not deal with higher classification, except when the terms are, for clarity, used as part of a recent revision, such as Kumar 1974 on Acanthosomidae. There are eleven groupings within the superfamily and all have been given family status. The treatment of each family varies, depending on the present level of knowledge and whether recent revisions or...

African Aquaculture: A Regional Summary with Emphasis on Sub-Saharan Africa
Provedor de dados: 20
Autores: 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...

Leveraging regional growth dynamics in African agriculture
Provedor de dados: 31
Autores: Abdulai,   Awudu; Johnson,   Michael; Diao,   Xinshen.
This study focuses on public investments and policy reforms for leveraging growth spillovers at the Africa regional level. It reviews first the theory and evidence of knowledge and growth spillovers generally and second the evidence in the African context. Given the limited and scattered evidence of actual past spillovers, it reviews recent ex ante simulations using partial and general equilibrium models to stress the potential for spillovers from greater cooperation in agricultural research, and from trade liberalization, policy harmonization and investments in infrastructure. The results show that permitting greater crossborder transfers and adopting improved technologies could have large spillover multiplier effects on overall economic welfare in the...

Maize Revolutions in Sub-Saharan Africa
Provedor de dados: 31
Autores: Smale,   Melinda; Byerlee,   Derek R.; Jayne,   Thomas S.
There have been numerous episodes of widespread adoption of improved seed and long-term achievements in the development of the maize seed industry in Sub-Saharan Africa. This summary takes a circumspect view of technical change in maize production. Adoption of improved seed has continued to rise gradually, now representing an estimated 44 percent of maize area in Eastern and Southern Africa (outside South Africa), and 60 percent of maize area in West and Central Africa. Use of fertilizer and restorative crop management practices remains relatively low and inefficient. An array of extension models has been tested and a combination of approaches will be needed to reach maize producers in heterogeneous agricultural environments. Yield growth overall has been...

The role of rural off-farm employment in agricultural development among farm households in low-income countries: Evidence from Zimbabwe
Provedor de dados: 31
Autores: Chikwama,   Cornilius.
This study examines the widely held view that earnings from rural wage employment can help farm households overcome constraints on farm investments. It uses a panel dataset of 359 randomly selected farm households from three resettlement areas in Zimbabwe over the period 1996/97 to 1998/99. It finds no evidence to support the hypothesis that income from rural wage employment contributes towards increasing farm investment for the sampled households, and it attributes this to very low savings rates on rural wage employment income. Further, it finds that levels of farm investment increase with the amount of labor and land used in farm production in the previous year, and for households with male and/or older household heads. It also finds an inverse relation...

Incentives for Fertilizer Use in Sub-Saharan Africa: A Review of Empirical Evidence on Fertilizer Response and Profitability
Provedor de dados: 31
Autores: 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.

Dairy development in Ethiopia
Provedor de dados: 31
Autores: 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...

The impact of Access to Credit and Training on Technological Adoption: A Case of the Rice Sector in Tanzania
Provedor de dados: 31
Autores: Nakano,   Yuko; Kajisa,   Kei.
Using an extensive household-level data set collected in Tanzania, this paper investigates the determinants of the technological adoption of rice cultivation and of paddy yield. We especially focus on the impact of credit and training on the adoption of modern technologies. Based on empirical results, we argue that modern inputs and improved practices of rice cultivation enhance the increase in paddy yield. We also argue that the impact of credit and training on the adoption of modern technologies can differ for different technologies. If the adoption of a specific technology does not require a large amount of cash, knowledge given by training is sufficient to enhance adoption. On the other hand, those who can access credit or self-finance can adopt...

Boosting smallholder production for food security: some approaches and evidence from studies in sub-Saharan Africa
Provedor de dados: 31
Autores: 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...

Sectoral and welfare effects of the global economic crisis on Uganda: a recursive dynamic CGE analysis
Provedor de dados: 31
Autores: Twimukye,   Evarist P.; Matovu,   John Mary; Levine,   Sebastian; Birungi,   Patrick.
This paper analyses the impact of the global economic and financial crisis on Uganda notably on macro-economic aggregates, sectoral output and household welfare, and the potential role of fiscal policy and reform in mitigating the impacts. We find that second round effects from a reduction in financial inflows such as remittances, foreign direct investments and overseas development assistance, as well as reduction in international demand from cash crops such as cotton, tea and coffee, could lead to a reduction in economic growth by 0.6 percentage points on average annually over the period 2008- 2010 compared to a baseline reflecting pre-crisis conditions. A surge in regional exports and early counter-cyclical policies in particular are found to dampen the...

Poverty, AIDS, Orphanhood, Gender, and Child Schooling in Sub-Saharan Africa: A Review of the Evidence
Provedor de dados: 31
Autores: Mather,   David.
There is growing concern that the HIV/AIDS epidemic may reduce long-term human capital development through reductions in child schooling in SSA, thus severely limiting the longterm ability of orphans and their extended families to escape poverty. In response, some have called for targeted schooling subsidies for orphans and other children made vulnerable by HIV/AIDS, on the assumption that such children are under-enrolled. This paper provides an overview of the data sources used by existing empirical studies that test for orphan schooling deficits and the methodological challenges that they face. It then reviews the empirical evidence on the effects of orphan status or adult mortality on child schooling, as well as the prevalence of orphans in SSA and...

Rice Miller Cluster in Ghana and Its Effects on Efficiency and Quality Improvement
Provedor de dados: 31
Autores: Sakurai,   Takeshi; Furuya,   Jun; Futakuchi,   Koichi.
This paper investigates the roles of industrial cluster on the efficiency of rice milling and the improvement of milled rice quality. The data were obtained in Kumasi area, central Ghana because the enhancement of domestic rice production is a urgent policy issue in this country, but little attention has been paid to the roles of clusters in post-harvest processing and marketing. Among 63 rice millers interviewed in the Kumasi area, 24 millers form a few clusters in the city of Kumasi, while others are scattered over 25 satellite towns around Kumasi, which enables us to examine the effect of the cluster. Regression analyses reveal that rice millers in the Kumasi clusters tend to adopt more advanced technology, and that the innovation increases milling...

Accelerating Africa's Structural Transformation Lessons from East Asia
Provedor de dados: 31
Autores: 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...

Revisiting the "Cotton Problem:" A Comparative Analysis of Cotton Reforms in Sub-Saharan Africa
Provedor de dados: 31
Autores: Delpeuch,   Claire; Vandeplas,   Anneleen; Swinnen,   Johan F.M.
The cotton sector has been amongst the most regulated in Africa, and still is to a large extent in West and Central Africa (WCA), despite repeated reform recommendations by international donors. On the other hand, orthodox reforms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylized contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors and analyze the potential consequences of orthodox reforms in WCA. We argue that the level of the world price and of government intervention, the degree of post-reform competition, as well as the degree of parastatal inefficiency, all contribute to making reforms less attractive (but not less pressing)...

Autores: Demont,   Matty; Zossou,   Esperance; Rutsaert,   Pieter; Ndour,   Maimouna; Mele,   Paul Van; Verbeke,   Wim.
In Benin, traditional parboiling is still widely practiced among rice processors, resulting in inferior grain quality. A new parboiler was introduced to improve the milling yield and quality of local rice. We conducted Vickrey second price auctions followed by a consensus session to elicit rural Beninese consumers’ willingness to pay for rice obtained through the new parboiler and two locally innovated parboilers. Relative to traditionally parboiled rice, consumers were willing to pay price premiums of 9–13% for rice obtained through a local parboiler using a container of which the bottom is a perforated metal, 27% for rice obtained through a local parboiler using wooden sticks at the bottom of the pot, and 25–34% for rice parboiled through the improved...

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.

Agricultural Productivity and Policies in Sub-Saharan Africa
Provedor de dados: 31
Autores: 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...

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...

Rice Price Stabilization in Madagascar: Price and Welfare Implications of Variable Tariffs
Provedor de dados: 31
Autores: Dorosh,   Paul A.; Minten,   Bart.
Given the large share of major staples in the budgets of the poor, governments in many developing countries intervene in food markets to limit variation in the prices of staple foods. This paper examines the recent experience of Madagascar in stabilizing prices through international trade and the implications of adjustments in tariff rates. Using a partial equilibrium model, we quantify the overall costs and benefits of a change in import duties for various household groups, and compare this intervention to a policy of targeted food transfers or security stocks.

Provedor de dados: 31
Autores: 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.

Revisiting the “cotton problem”: A comparative analysis of cotton reforms in Sub-Saharan Africa
Provedor de dados: 31
Autores: Delpeuch,   Claire; Vandeplas,   Anneleen; Swinnen,   Johan F.M.
The cotton sector has been amongst the most regulated in West and Central Africa (WCA), and still is to a large extent, despite repeated reform recommendations by international donors. On the other hand, orthodox reforms in East and Southern Africa (ESA) have not always yielded the expected results. This paper uses a stylized contracting model to investigate the link between market structure and equity and efficiency in sub-Saharan cotton sectors and analyze the potential consequences of orthodox reforms in WCA. We argue that the level of the world price and of government intervention, the degree of post-reform competition, as well as the degree of parastatal inefficiency, all contribute to making reforms less attractive (but not less pressing) to farmers...

This paper draws together findings from different elements of a research project examining critical components of pro-poor agricultural growth and of policies that can promote such growth in poor rural economies in South Asia and Sub-Saharan Africa. Agricultural growth, a critical driver in poverty reducing growth in many poor agrarian economies in the past, faces many difficulties in today’s poor rural areas in South Asia and Sub-Saharan Africa. Some of these difficulties are endogenous to these areas while others result from broader processes of global change. Active state interventions in ‘kick starting’ markets in 20th century green revolutions suggest that another major difficulty may be current policies which emphasize the benefits of liberalization...

Generating Plausible Crop Distribution and Performance Maps for Sub-Saharan Africa Using a Spatially Disaggregated Data Fusion and Optimization Approach
Provedor de dados: 31
Autores: 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
Provedor de dados: 31
Autores: 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...

On the Growth Performance of Sub-Saharan African Countries
Provedor de dados: 31
Autores: Busse,   Matthias.
The article discusses some of the most important reasons for the poor growth performance of most countries in sub-Saharan Africa. While high protection levels in high-income countries in Europe and North America for agricultural trade have been cited as a major impediment for the development of African countries, they are unlikely to play a major role. Rather, a lack of integration into world markets and the relatively poor quality of African institutions are more likely to explain the low growth rates.

Autores: Maredia,   Mywish K.; Howard,   Julie A.; Boughton,   Duncan; Naseem,   Anwar; Wanzala,   Maria N.; Kajisa,   Kei.
The purpose of this paper is to provide a conceptual framework that can be used by agricultural leaders, administrators, policy makers, and seed program managers to (1) understand key factors affecting seed system development; and (2) compare organizational and institutional strategies for increasing seed system effectiveness. A literature review of recent studies on seed system development in Sub-Saharan Africa (SSA) was undertaken to achieve these objectives. The studies reviewed included published and unpublished reports, monographs, and case studies.

An Updated Look at the Recovery of Agricultural Productivity in Sub-Saharan Africa
Provedor de dados: 31
Autores: 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...

Income Growth and Gender Bias in Childhood Mortality in Developing Countries
Provedor de dados: 31
Autores: 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...

Macro Trends and Determinates of Fertilizer Use in Sub-Saharan Africa
Provedor de dados: 31
Autores: Naseem,   Anwar; Kelly,   Valerie A.
To reverse the declining trends in soil fertility levels in Sub-Saharan Africa (SSA), the use of fertilizers and other land augmenting technologies needs to increase. While overall fertilizer consumption in SSA has increased by as much as 200% from 1970 levels, the growth has been highly variable across countries, regions and time. Fertilizer use is significantly lower than that observed in other parts of the developing world, especially Asia, where fertilizer (along with other productivity enhancing technologies) has been credited with the large increases in yields. Moreover data for the 1990s suggests that overall fertilizer consumption in SSA has been declining. Designing appropriate policies and interventions to stimulate fertilizer demand and supply,...

Autores: Davis,   Kristin E.; Ekboir,   Javier M.; Mekasha,   Wendmsyamregne; Ochieng,   Cosmas M.O.; Spielman,   David J.; Zerfu,   Elias.
This paper examines the role of postsecondary agricultural education and training (AET) in Sub-Saharan Africa in the context of the region’s agricultural innovation systems. Specifically, the paper looks at how AET in Sub-Saharan Africa can contribute to agricultural development by strengthening innovative capabilities, or the ability to introduce new products and processes that are socially or economically relevant to smallholder farmers and other agents in the agricultural sector. Using AET in Ethiopia and Mozambique as case studies, the paper argues that while AET is conventionally viewed in terms of its role in building human and scientific capital, it also has a vital role to play in building the capacity of organizations and individuals to transmit...

Investing In African Agriculture to Halve Poverty By 2015
Provedor de dados: 31
Autores: Fan,   Shenggen; Johnson,   Michael; Saurkar,   Anuja; Makombe,   Tsitsi.
This paper proposes a simple methodology to estimate the agricultural spending that will be required to achieve the Millennium Development Goal of halving poverty by 2015 (MDG1) in 30 sub-Saharan African countries. This method uses growth-poverty and growth-expenditure elasticities to estimate the financial resources required to meet the MDG1, considering both the direct and indirect impacts of agricultural spending on poverty reduction. The paper attempts to address a key knowledge gap by improving estimation of MDG costs at both the regional and country levels.

Is Food Insecurity More Severe in South Asia or Sub-Saharan Africa?:  A Comparative Analysis Using Household Expenditure Survey Data
Provedor de dados: 31
Autores: Smith,   Lisa C.; Wiesmann,   Doris M.
This paper uses data from national household expenditure surveys to explore whether food insecurity is more severe in South Asia or Sub-Saharan Africa. It employs two indicators of the diet quantity dimension of food insecurity, or the inability to access sufficient food: the prevalence of food energy deficiency and the prevalence of severe food energy deficiency. It also employs two indicators of the diet quality dimension, indicating lack of access to nutritious food: the prevalence of low diet diversity and the percent of energy from staple foods. It finds the regions’ food energy deficiency prevalences to be quite close (51 percent in South Asia, 57 percent in Sub-Saharan Africa). However, the prevalence of severe food energy deficiency, which is more...

While greater growth in agriculture and the broader rural sector is crucial for ameliorating Africa's high levels of poverty and malnutrition, developing strategies to achieve these objectives is hindered by a number of factors, including the broad array of interventions needed, the lack of accurate data, and dearth of trained local policy analysts. As such, this paper proposes a Strategic Analysis Knowledge Support System (SAKSS) in which data, tools, and knowledge are compiled, analyzed, and disseminated for the purposes of identifying a set of priority investment and policy options to promote agricultural growth and rural development. These analyses can in turn help inform the broader process of designing, implementing, and monitoring and evaluating a...

Food Reserve Stocks and Critical Food Shortages - a Proposal Based on the Needs of Sub-Saharan Africa
Provedor de dados: 31
Autores: 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...

MAIZE IN EASTERN AND SOUTHERN AFRICA: "SEEDS" OF SUCCESS IN RETROSPECT
Provedor de dados: 31
Autores: Smale,   Melinda; Jayne,   Thomas S.
This synthesis revisits the "maize success story" in Sub-Saharan Africa, drawing selectively from an extensive published literature about maize seed technical change and related policies. The review focuses on the countries of Kenya, Zimbabwe, Zambia, and Malawi, where maize is most important in the food economy, and refers to the period when maize became a dominant food crop through the 1990s. The term "success" is equivocal in this case, both because of the difficult of establishing the appropriate counterfactual and because some of the policies that contributed to success in one period later led to decline. While the "seeds" themselves were the result of innovative, successful maize breeding, boom periods in maize production were episodic and the public...

Deforestation in Sub- Sahara Africa
Provedor de dados: 31
Autores: 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...

Autores: Miito, Gilbert John; Banadda, Noble.
Municipal solid waste management is one of the major environmental problems of developing countries. Investments in solid waste management would not only translate into jobs and income but also a cleaner environment. Over years a number of solid waste management technologies have been carried out in many developing parts of the world. Some were successful in generating lasting impacts on the improvement of solid waste management, however, many technologies failed due to unsustainability. This is partly attributed to differences in waste characteristics between developed countries and the less developed countries and the resource constraints in less developed countries. On the other hand, less developed countries are also known for being energy deprived and...

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.
