Summary
The document details the stakeholder engagement process and technical data used to develop a regional tool for integrated water and economic planning in the Berg WMA. It includes records of workshops and meetings with provincial government, local municipalities, and academic institutions. Technical appendices provide marginal values of water by crop, estimated irrigated agriculture water requirements, and forecasts for urban water demand for 2025 and 2040. The text also validates these bottom-up estimations against the WARMS database and Aurecon's Water Resources Simulation Model, while assessing the economic opportunity cost of potential supply deficits in terms of GVA and employment.
Key insights
- Stakeholders generally agreed that the Western Cape Government’s Sustainable Water Management Plan (SWMP) forum is an appropriate mechanism for coordinating integrated water and economic development, although it requires improved relations with Local Municipalities and the Department of Water and Sanitation to translate recommendations into authorisation decisions.
- There has been a shift in stakeholder perception toward accepting that water and economic development cannot be planned in isolation, with a growing consensus on the need to consider the economic value of water use in strategic decision-making.
- The project's bottom-up irrigated agriculture water requirement estimates for the Berg WMA were validated as reasonably close to Aurecon's Water Resources Simulation Model, which estimated 239 Mm3/a for its specific study area, while the project's clipped estimate for that same area was 201 Mm3/a.
- The marginal value of water in agriculture is heavily influenced by crop type and soil fertility; for example, the overall mean marginal value for peaches is 4.84, while for wheat it is 0.14.
- Forecasts for total urban water requirements in the region show significant projected growth, with the total increasing from 392,086,039 m3 in 2011 to a mid-range forecast of 896,228,911 m3 by 2040.
