Africa, particularly Sub-Saharan Africa (SSA) is faced with deep rooted poverty, malnutrition and inadequate food production. Key factors that aggravate these problems include high population growth, low agricultural productivity, high natural and man-made tragedies such as climatic variability and change, conflicts and war. About 70% of SSA’s economy is dependent on agriculture and the majority of the population is engaged in agriculture. Given the low labor, land and water productivities in most parts of SSA, production growth in SSA has come primarily from extending agricultural land and not on intensifying agriculture. This also has substantial implication on the environment. There is however tremendous scope and opportunity to reverse these trends, improve livelihoods and create wealth. It is against this background that the programs and contributions of the International Water Management Institute (IWMI) towards improved water and land management in Africa for agricultural and other developments are presented in this paper. IWMI’s roles in terms of understanding the challenges and the importance of water and land management are emphasized. The functional arrangements of IWMI’s sub- regional offices and their respective research priorities, the current key research, capacity building and knowledge management activities of IWMI in Africa, and its research partnerships are discussed.

Municipal sewage water vehicles a wide variety of emerging organic pollutants. Some can be of natural origin, but they are mainly considered as anthropogenic. After secondary biological treatment, organic pollutants may not completely degrade (as pharmaceuticals), or give metabolites more persistent than parent compounds (as alkylphenols), or react during sewage treatment process to be reactivated (as hormones, pharmaceuticals). Some of these contaminants have been shown to act as endocrine disruptors. In reclaimed waters, they have been detected at levels of ng to µg/l. In arid and semi-arid countries, effluent reuse is often promoted as an alternative water resource to meet agricultural water needs and to protect receiving waters and public health. Occurrence of emerging organic contaminants in reclaimed water and irrigated soils have been always overlooked in these regions. Even though, and depending on their physico-chemical properties, hydrophobic chemicals may accumulate at variable depth while the more polar ones may be transported through soil column and may reach groundwater. According to laboratory and field experiments, aquifer contamination should be of concern in some cases. Plant uptake of organic chemicals from irrigated soils have been investigated. Available data shows that contamination through uptake is of little concern for most toxic compounds.

Where rapid urbanization is outpacing urban capacities to provide sound sanitation and wastewater treatment, most water sources in city vicinity are heavily polluted. This is of great concern as many of the leafy vegetables eaten raw in the cities are produced in these areas. Following the new WHO guidelines, different non-treatment options at farm, market, and kitchen level were field tested for health risk reduction with special consideration to efficiency and adoption potential. As most households are used to vegetable washing (although ineffectively), an important entry point for risk reduction is the increased emphasis of the new guidelines on food preparation measures. A combination of safer irrigation practices (water fetching, on-farm treatment, and application), the allocation of farmland with better water sources, and improved vegetable washing in kitchens appear to be able to reduce the potential risk of infections significantly, although it might not be possible to reach the ideal threshold without some kind of wastewater treatment. The on-farm trials carried out in Ghana also explored the limitation of other risk reduction measures, such as drip irrigation, crop restrictions and cessation of irrigation under local circumstances considering possible incentives for behaviour change.

The Tunisian Dorsal area is representative of the semiarid Mediterranean region in terms of water resources availability as well as exceptional rainfall characteristics, runoff generation, and soil loss risk. In this context, soil properties, surface management practices together with highly intensive rainfall make the soils vulnerable to erosion. If the exceptional rainfall characteristics are linked to different erosion types, the erosion risk could be evaluated in a simple and straightforward way. In this regard, a short time-scale rainfall data base from the Dorsal area was analysed in the paper. The procedure used involves finding a representative duration between 1-60 min for the exceptional rainfall characteristics. Rainfall intensities of different return periods are then related to the different erosion types. The identified exceptional rainfall durations between 1-60 min were analyzed in terms of number of events, depth, average intensity and maximum intensity. Results show that the 15-min duration maximum intensity can be used to evaluate erosion risk based on soil erosion type. The developed methodology can be used to evaluate erosion risk in semiarid regions based on exceptional rainfall characteristics. In practical terms the results can be used to better manage catchments that are vulnerable to soil erosion.
