Waste to energy technologies for solid waste management a case study of Uganda CIGR Journal
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...

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...

Enfors, Elin I; Natural Resources Management, Department of Systems Ecology, Stockholm University, Sweden; elin@ecology.su.se; Gordon, Line J; Stockholm Resilience Center, Stockholm University, Sweden; Natural Resources Management, Department of Systems Ecology, Stockholm University, Sweden; line@stockholmresilience.su.se; Peterson, Garry D; Department of Geography and McGill School of Environment, McGill University, Canada; Stockholm Resilience Center, Stockholm University, Sweden; garry.peterson@mcgill.ca; Bossio, Deborah; International Water Management Institute (IWMI), Sri Lanka; d.bossio@iwmi.cgiar.org.
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–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 ArchiMer
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 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...

Snakebite in Bobo-Dioulasso, Burkina Faso: illustration of realities and challenges for care based on a clinical case J. Venom. Anim. Toxins incl. Trop. Dis.
Kyelem,CG; Yaméogo,TM; Ouédraogo,SM; Zoungrana,J; Poda,GEA; Rouamba,MM; Ouangré,A; Kissou,SA; Rouamba,A.
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 J. Venom. Anim. Toxins incl. Trop. Dis.
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 Naturalis
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 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...

Rice Miller Cluster in Ghana and Its Effects on Efficiency and Quality Improvement AgEcon
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...

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...

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...

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.

Revisiting the “Cotton Problem”: A comparative analysis of cotton reforms in Sub-Saharan Africa AgEcon
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)...

Is Food Insecurity More Severe in South Asia or Sub-Saharan Africa?: A Comparative Analysis Using Household Expenditure Survey Data AgEcon
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...

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...
