Prospects for agricultural water management
The largest immediate threats to Samoa’s natural resources, including water, are extreme events associated with climate change and climate variability, such as cyclones, floods and droughts. Other threats exist, such as amongst others waste proliferation, poor sanitation systems, unsustainable exploitation of resources and poorly planned development initiatives. However, these threats are more manageable with timely and effective interventions (MNRE, 2013).
Water demand is increasing with population wealth, urbanization and an increase in major developments, including tourism. Despite considerable effort in water demand management measures, including metering, leakage detection and repair, tariff incentives and conservation awareness campaigns, per capita consumption of water are predicted to rise. Samoa recognizes the benefits of adopting more integrated water resources management approaches (SOPAC, 2007).
The potential for increased hydroelectric power generation or irrigation will directly compete with more traditional uses (SPC, 2012).
