In sub-Saharan Africa (SSA), food security can be influenced by many factors including farmer productivity, access to soil amendments, labor availability, and family incomes (just to name a few). In this paper, we suggest that an additional issue contributes to food insecurity and has been historically absent from the discussion, namely access to cooking energy, particularly for very low income, food insecure individuals. This paper examines the most recent literature that describes the central role played by wood fuels, in particular firewood and charcoal, as a vital, though controversial, source of fuel used by the vast majority of rural and urban sub-Saharan Africans. We explore the reality that although the health risks of collecting and using firewood and charcoal in traditional manners are real, policy makers, researchers, and donors need to address the sustainability and viability of the current fuel types used by the majority of people. We end the paper with a series of practical suggestions for improving the wood fuel systems as they currently exist in the region.

Agriculture And Food

Agricultural development in sub-Saharan Africa faces daunting challenges, which climate change and increasing climate variability will compound in vulnerable areas. The impacts of a changing climate on agricultural production in a world that warms by 4 ° C or more are likely to be severe in places. The livelihoods of many croppers and livestock keepers in Africa are associated with diversity of options. The changes in crop and livestock production that are likely to result in a 4 ° C+ world will diminish the options available to most smallholders. In such a world, current crop and livestock varieties and agricultural practices will often be inadequate, and food security will be more difficult to achieve because of commodity price increases and local production shortfalls. While adaptation strategies exist, considerable institutional and policy support will be needed to implement them successfully on the scale required. Even in the 2 ° C+ world that appears inevitable, planning for and implementing successful adaptation strategies are critical if agricultural growth in the region is to occur, food security be achieved and household livelihoods be enhanced. As part of this effort, better understanding of the critical thresholds in global and African food systems requires urgent research.

Impacts Of Climate Change

Climate change is unequivocal and nothing hides itself from its negative repercussions. Countries in sub-Saharan Africa will continue to be impacted due to their low adaptive capacities and geographic position. Unfavourable weather trends coupled with climatic variations will have adverse effect on agricultural sector which is the main source of livelihood to rural households on the continent. This literature review article assessed the impacts of climate change on agriculture and food security in Africa. The lives of several in Africa cling on agriculture as it supports majority of the population. However, since over 90 percent of agriculture system in the region depends on rainfall, livelihoods of the citizens on the continent have been hit hard due to rising temperature, erratic rainfall and extreme weather conditions.

The objective of this short review is to contribute to the debate on the role of agriculture transformation in the development process and as an engine to reduce poverty and improve general wellbeing through better access to nutrients in Mozambique. Agricultural services are organized by Provinces but still there is no accurate data on food production, consumption and trade trends in a large sample. It is recognized the complexity of the food security concept and the need of a multidimensional definition and approach. The increase in agricultural productivity can probably be seen as a necessary but not a sufficient condition to achieve long term food security in Mozambique or Sub-Saharan Africa.  Competing views about the relevance of agriculture for growth and development imply different policy priorities in Africa.

In East Africa, the prevalent Bemisia tabaci whiteflies on the food security crop cassava are classified as sub-Saharan Africa (SSA) species. Economically damaging cassava whitefly populations were associated with the SSA2 species in the 1990s, but more recently, it has been to SSA1 species. To investigate whether biological traits (number of first instar nymphs, emerged adults, proportion of females in progeny and development time) of the cassava whitefly species are significant drivers of the observed field abundance, our study determined the development of SSA1 sub-group (SG) 1 (5 populations), SG2 (5 populations), SG3 (1 population) and SSA2 (1 population) on cassava and eggplant under laboratory conditions. SSA1-(SG1-SG2) and SSA2 populations’ development traits were similar. Regardless of the host plant, SSA1-SG2 populations had the highest number of first instar nymphs (60.6 ± 3.4) and emerged adults (50.9 ± 3.6), followed by SSA1-SG1 (55.5 ± 3.2 and 44.6 ± 3.3), SSA2 (45.8 ± 5.7 and 32.6 ± 5.1) and the lowest were SSA1-SG3 (34.2 ± 6.1 and 32.0 ± 7.1) populations. SSA1-SG3 population had the shortest egg–adult emergence development time (26.7 days), followed by SSA1-SG1 (29.1 days), SSA1-SG2 (29.6 days) and SSA2 (32.2 days). Regardless of the whitefly population, development time was significantly shorter on eggplant (25.1 ± 0.9 days) than cassava (34.6 ± 1.0 days). These results support that SSA1-(SG1-SG2) and SSA2 B. tabaci can become highly abundant on cassava, with their species classification alone not correlating with observed abundance and prevalence.

Poor Soil

Cassava makes an important contribution to improving food security and rural incomes in sub-Saharan Africa, as it is tolerant of drought and poor soil and its cultivation does not require much labour. However, the fresh roots are bulky and perishable and need to be processed before they can be marketed; processing also removes the cyanogens which make many varieties poisonous in their raw form. Cassava roots are turned into granules, flours, pastes and chips, with a wide range of flavours and appearances for different areas and markets. Many different processing techniques are used, some of which make intensive use of fuelwood while others require a plentiful water supply. These requirements, as well as the need for a good transport and marketing infrastructure, limit the expansion of cassava production in sub-Saharan Africa, but technical solutions are being found.

Climate variability and change are recognized as the greatest challenge to crop production and food security in sub-Saharan Africa. This work assesses farmers’ perception on the contribution of improved varieties of sorghum and millet in the search for food security in Cinzana rural commune of Mali in the current context of climate change.The methodology was based on focus group surveys with both, the decentralized technical services, administrative and municipal authorities, NGOs, farmer organizations and producers but also farmer exchanges visits on improved varieties tested in farmer’s field.The result shows that climate change is described by the majority of farmers (87%) as decrease in rainfall amount and length of rainy seasons, high increases in temperature and high deforestation and water scarcity. Unpredictability of climate, (80%), drought (70%) and heavy rain (65%) occurrence were identified as major perception of farmers on risks in climate for crop production and soil degradation. After farmers’ study tour, 80% of the participants mentioned a better growth of plants and increase of soil moisture with the use of contour ridges tillage as a water conservation technology. Adapted cycle (55%) and higher yield (37%) of improved varieties were farmer’s main drivers for adoption of improved millet and sorghum varieties.The study revealed that local farmers have substantial knowledge on climate variabilities and risks and also are aware of some adaptation strategies. However, for wide scale adoption of effective strategies, capacity strengthening appeared a prerequisite.
