Climate change threatens the livelihood of rural communities that depend on natural resources for food. Many people in developing countries living in the rural areas depend on indigenous food resources which in years are scarce and in poor supply as a result of marginal and erratic rainfall, low soil and ambient temperatures below the minimum temperature.
We describe the nature of recent (50 year) rainfall variability in the summer rainfall zone, South Africa, and how variability is recognised and responded to on the ground by farmers. Using daily rainfall data and self-organising mapping (SOM) we identify 12 internally homogeneous rainfall regions displaying differing parameters of precipitation change.
In this article, the Author’s opening remark immediately shows which should be the cultural psychiatrist’s most proper approach to the diachronic and ethnographic broadness of the human struggle for maintaining well-being: “People have sought comfort for their miseries and a cure for their troubles since prehistoric time” (Romm, 1994).
Climate change is an environmental phenomenon with the potential to exacerbate existing disaster risks and cause extensive human, financial and environmental losses. The Mooifontein agricultural region in South Africa is considered to be a region vulnerable to climate change– associated risks.
Improved agricultural productivity using conservation farming (CF) systems based on non-inversion tillage methods, have predominantly originated from farming systems in sub-humid to humid regions where water is not a key limiting factor for crop growth.
Available information pertaining to water temperature in riverine ecosystems is examined and consolidated into an overview that describes the spatial and temporal variation in water temperature, the importance of water temperature in lotic ecosystems, the measurement and modelling of water temperature, anthropogenic factors that modify water temperature, the effects of temperature changes on th
Dry spells and climatic hazards are responsible for maize output decline, sometimes to levels below potential yield levels. There is a pressing need to reduce the gap between actual and potential maize yield/ha, especially among farmers in semi-arid regions.
