Increased frequency and intensity of climate variability appears through highly variable and erratic rainfall together with rising temperatures, floods and droughts.
Impact of Climate Change on African Agriculture: Crops like sorghum, cassava, yam, and pearl millet have generally experienced small losses, and even gains in some places, in production area; these crops could thus become a viable alternative for Eastern and Southern African farmers.
Climate change, population growth, and an increase in world trade may all contribute to a higher prevalence of crop pests and a more frequent occurrence of major pest outbreaks. According to the report, crop pests account for around one-sixth of farm productivity losses.
A higher incidence of pests would require more pesticides, which would in turn increase the risk of hazardous residues in food. Rising temperatures and humidity will also increase the rate of development of parasites and diseases that affect livestock, such as trypanosomosis, East Coast fever, and Rift Valley fever; disease outbreaks that may reduce exports and cause farmers lose profits are projected to worsen as temperatures rise.
Livestock diseases also have impacts on human health. Fishery production in Africa could also be greatly affected. The report identifies fisheries in 23 African countries as highly vulnerable to climate change. These impacts will have negative effects on the incomes and food security of millions of African producers.
Such strategies will require: Juan Carlos Mora Betancourt.Livestock Disease and African Food Security A serious problem in Africa today is the emergence of rampant, deadly strains of disease that are affecting livestock and ravaging populations of pigs and cattle in many African nations, putting food security at risk in many populations of various.
Research with real world impact. Our research. Research; Our research; A-Z of research groups have identified two genes that may prove key to protecting against African sleeping sickness in people and a wasting disease in cattle.
The N’Dama are the oldest of African cattle breeds and are not seriously affected by the condition, as it. At Farm Africa, an international charity working to support smallholder farmers across eastern Africa, we recognise the importance of livestock in food and nutrition security and we work across diverse livestock systems ranging from pastoral, agro-pastoral and urban-peri-urban.
Food self-sufficiency advocated in the s and supported by many countries was replaced in the s by the concept of food security, the objective of which is to make available all foodstuffs in sufficient quantities and with the adequate nutritional qualities, whatever is their origin, be they produced locally, imported, or donated as food aid.
Diseases of Importance at the Wildlife/Livestock Interface in Kenya1 Elizabeth Wambwa, Kenya Wildlife Service, Nairobi, Kenya markets of Europe and the Middle East has had a negative impact on livestock production (Grootenhuis ).
In Kenya, between and , wildlife in the food security). Although many diseases can infect.
These impacts will have negative effects on the incomes and food security of millions of African producers. The report’s authors argue that strategies do exist to address the impact of pests and diseases on agricultural systems.
