Drivers of change in sustainable water management and agricultural development in South Africa: a participatory approach

摘要

To develop a sustainable and vibrant agricultural sector capable of meeting the food demands of the growing population, freshwater in agriculture must be used efficiently and effectively to ensure sustainable socio-economic development of the economy. Issues such as climate change, land degradation, water pollution and population growth among others will continue to influence sustainable water management and agricultural development in South Africa. The challenge facing South Africa is how to ensure water and food security in the face of recurring droughts, increasing urbanisation and decreasing freshwater resources. South Africa will need to understand the drivers influencing water management and agricultural development to develop improved methods for planning sustainable water management and agricultural development. This study made use of a participatory approach, which provided a valuable platform for the identification of drivers of change, their charac- teristics and relative importance regarding agricultural water resource management and agricultural development in South Africa through participation. The study identified and analysed 5 clusters and 37 drivers, and their relative importance in influencing water management agricultural development in South Africa. The study found that population growth; educa- tion, climate extremes, irrigation technology, land degradation, rainwater harvesting, government support, and land reform, mismanagement of public resources and net agricultural export were among the most influential drivers in agricultural water management. The implication of these results for sustainable agricultural water management is discussed.
