While the report names the Maldives as the nation that would be affected the worst, other countries, including India, would suffer significant losses to their economies. The net effect could be of increased food and water deprivation, affecting millions in these countries. Given most of these nations are still developing economiesand are trying to pull nearly 500 million (ADB estimates) out of povertythe business-as-usual approach is quite damning. Agriculture, especially, is set to suffer the worst, given rising temperatures could mean frequent drought and floods and increased salinity of soil, with Bangladesh and India, two of the regions largest rice-producing nations, seeing a 23% fall in yield for the crop. India will see a 400 billion cubic metre shortfall in precipitation by 2100 if no action is taken at the earliest. Reduced precipitation will mean hydropower, driven by rain-fed rivers, would face depletionBhutan stands to lose the most from this considering 99% of its power supply is from hydel projects. The changing climatic conditions, the ADB says, will also make vector-borne diseases endemic to the region, resulting in significant outgo on public health overheads. The
report recommends many adaptation strategies, from the use of drought/flood resistant crops to ensure food security, to new thinking on urban design and planning for conserving surface water and checking spread of diseases.
