Rainwater harvesting (RWH) is a promising technology for increasing water availability for crop production of smallholder farmers in the semi-arid regions of the Limpopo Basin. A few studies on rainwater harvesting have been conducted in the basin at small plot and farmer field scales. Results from Mozambique, Zimbabwe and South Africa indicate substantial benefits to crops grown using a range of rainwater harvesting techniques. However, there have been no catchment and basin level studies to investigate the impacts of wide scale adoption at these levels. A methodology flow chart is proposed for systematically investigating the impacts of out-scaling of these in-field and ex-field rainwater harvesting techniques. The method proposes an analysis of levels of adoption to help identify optimum levels that will maximize land and water productivity while minimizing negative hydrological and ecological impacts at catchment or basin scales.

African governments have ambitious plans to expand irrigated agriculture, though existing smallholder schemes have largely failed to use land and water sustainably or become profitable. Six government-owned irrigation schemes in Mozambique, Tanzania and Zimbabwe were assessed to identify common policy barriers and opportunities for higher productivity among smallholder farmers. Issues like insecure land tenure systems, unclear institutional arrangements and poor access to markets have contributed to limited profitability. Reform of currently insecure land tenure, strengthening farmer organizations and reforming policies are recommended so that governments step back from scheme management and foster market linkages to enable more profitable irrigated agriculture.

This study provides an overview of extension influence on the adoption of irrigation innovations in developed and developing countries, and finds that extension plays a more significant positive role in influencing soft technology adoption in developing countries. Case studies on the nature, use and availability of extension advice in six irrigation schemes in Tanzania, Mozambique and Zimbabwe are presented. The use of government extension officers varied significantly, with extension use not linked to farm outcomes. The results suggest the need to support more diverse sources of advice and to promote institutional reform in south-eastern Africa.
