Impacts Water

97% of the water supply in Malaysia is drawn from surface water flows, and storage depends almost entirely on reservoirs. This context leaves Malaysia vulnerable to extremes and unpredictability in precipitation rates. Uncertainty in downscaled climate modelling presents a major challenge to Malaysia’s water planning. Malaysia’s Biennial Update Report (2015) places an increased emphasis on the importance of integrated water resource management and basin management, including nature-based solutions. However, the threat climate change represents to natural ecosystems in Malaysia has implications for its water management. Degraded basin ecosystems increase drainage rates, exacerbating downstream flooding. An additional challenge reported by regional governments in Malaysia is the encroachment of urban sprawl onto flood prone areas, which might otherwise have acted to buffer flood water (Managing the Flood Problem in Malaysia, 2007).
