Abstract

Central Sumba Regency and Tana Mbanas village are the driest areas in Indonesia where water shortage happened and drought become annual event. Both Central Sumba Regency and Tana Mbanas village are facing problem of become growing population with limited water supply because of drought. Hence, this paper aimed to analyse water supply needs in Central Sumba Regency and Tana Mbanas village as resilience strategy in drought disaster risk reduction. This research investigated the water availability and sufficiency in Central Sumba Regency and Tana Mbanas village by water supply analysis. Existing population of Central Sumba Regency and Tana Mbanas village have been projected for the next 10 years using exponential method. Result of study found that projected 2030 water supply needs in Central Sumba Regency (214.52 l/sec) cannot fulfill the needs (only 2-163 l/sec) except the RWS Mambitul (228 l/sec). It is also found that water supply needs in Tana Mbanas village (3.40 l/sec) in 2030 is bigger than the capacity of potential ground water bore well (< 2 l/sec) that located in SDM Waiurang. The water supply needs in Central Sumba Regency and Tana Mbanas village in 2030 cannot be provided by the water availability in those areas. This research meets conclusion that water supply needs analysis would become a resilience strategy in drought disaster risk reduction. Keywords: water supply, Sumba drought, resilience strategy, disaster risk reduction.
