Impacts Water

Water Security, particularly considering issues of storage and distribution, requires urgent attention and needs to take into account projected population growth, whilst reducing demand for treated water, using more rainwater, improving efficiency of the distribution system, and improving water storage capacity. Increasing water demand from the residential, commercial, agriculture, and tourism sectors is exacerbated by changes in rainfall patterns and a limited water storage capacity (NDC). At present, water to supply the agricultural sector is heavily dependent on rainfall and the country’s water storage capacity is constrained by the natural topography of its islands. Most of the country’s farmers currently use irrigation to provide water to their crops, which means that any restrictions placed on water use during extended dry spells impacts their livelihoods. Furthermore, crop failure is becoming more common in the coastal zones as a result of increased flooding and higher levels of soil salinity.
