由于气候变化，预计南非干旱、极端事件和高风速的频率和强度将在下个世纪增加。《国家水资源战略2》（NWRS2）确定了今后20年我国水资源管理的总体战略方向。然而，该战略并没有制定一个专门为农业用途量身定制的框架，其中没有具体的措施和目标。因此，为了实现农业用水的可持续性，提出了四个主要战略目标，研究机构可以通过善治来关注和促进这些目标。该战略强调：(1)作物研究，寻找新的耐旱耐热品种；(2)加强农业实践研究；（三）提高农业用水效率；(4)将所有这些战略目标整合到一个可持续的研究框架中。最后，该研究呼吁迅速采取行动和实施。意义：该框架为南非高等教育、农业和资源管理领域的利益相关者和政策制定者提出了新的研究视野，旨在根据千年发展目标的规定，到2030年提高整体农业可持续性。
The frequency and intensity of drought, extreme events and high wind velocities in South Africa are expected to increase in the next century as a result of the changing climate. The National Water Resource Strategy 2 (NWRS2) has set out the general and strategic directions for water resources management in the country for the next 20 years. However, the strategy does not draw a framework tailored specifically for agricultural use, with specific measures and goals. Therefore, to reach sustainability of water in agriculture, four major strategic goals are suggested, on which research institutions can focus and promote through good governance. The strategy emphasises: (1) crop research to find new droughtand heat-tolerant and resistant breeds and varieties; (2) intensified research in agricultural practices; (3) increasing the efficiency of water use within agriculture; and (4) integrating all these strategic goals within a sustainable research framework. Finally, the research calls for rapid action and implementation.Significance:The framework is proposed for stakeholders and policymakers in higher education, agriculture and resources management in South Africa for new research horizons at national level to improve overall agricultural sustainability by 2030 as stipulated by the Millennium Development Goals.
