Role of ecoclimatology in rural planning

V.P. Subrahmanyam, P. Viswanadham


Using the two basic ecological parameters, temperature and rainfall, water balances on monthly and yearly basis have been computed for assessing the ecological potentialities utilising the revised scheme of Thornthwaite and Mather for three selected stations in Andhra Pradesh viz. 1. The coastal semiarid station - Visakhapatnam. 2. The inland dry subhumid station - Narsipatnam and 3. The moist sub-humid station - Araku. Different components of the water balance of these three faces have been discussed in relation to different crop potentialities. The study records that Visakhapatnam and Narsipatnam do not have water surplus while Araku shows a water surplus of 241 mm annually. The soil moisture at Araku attains saturation. The aridity indices suggest that the coastal areas are seen to prove to "large water defficiency" whereas the Central areas has "moderate water deficiency" and the interior high land has almost "no water deficiency"
