Purpose The study explored the impacts of climate change on water resources, and the community-based adaptation practices adopted to ensure water security in a rural community in Limpopo Province, South Africa. Design/methodology/approach The study was conducted in Limpopo Province, South Africa. The participatory approach was used to allow community members to share their challenges of water scarcity, and the measures they have developed to cope with inconsistent water supply. Findings The study results show that the community obtains water for household consumption from the reticulation system supplied by Mutale River and the community borehole. These resources are negatively impacted by drought, change in the frequency and distribution of rainfall, and increased temperature patterns. The water levels in the river and borehole have declined, resulting in unsustainable water supply. The community-based adaptation practices facilitated by the water committee include observance of restrictions and regulations on the water resources use. Others involve securing water from neighbouring resources. Originality/value This type of community-based action in response to climate change could be used as part of rural water management strategies under climate change.

The Reconstruction and Development Programme adopted by the Government of National Unity is more than a list of the services required to improve the quality of life of the majority of South Africans. It is not just a call for South Africans to unite to build a country free of poverty and misery; it is a programme designed to achieve this objective in an integrated and principled manner. Based on the strategic objectives, as highlighted in the White Paper on Water Supply and Sanitation Policy, with regard to alleviating the chronic potable water shortages in South Africa, this thesis investigates a design methodology to supply potable water through the use of wind energy. The design focuses on small rural off-grid developments where grid electricity either has not or will not reach, and where renewable energy is the only viable option. This thesis provides an overview of wind energy and presents the fundamentals of wind power calculations. It also formulates an overview of the historic and present situation with regards to potable water supply, and reflects on the need for urgent intervention. The feasibility of using wind energy to supply potable water to rural communities in South Africa is explored in a case study. The various problem areas are identified and examined and a wide range of possible solutions are recommended. A final flow chart for the system design is proposed, thus ensuring comprehensive design methodology from which future design of similar systems can be based.
