MODET: A modular model for estimating spatially distributed evapotranspiration, surface temperature and energy balance

Abstract

Competition for water: • Oct 2011 - World population reaches 7 billion. • 2042 - Population is projected to reach 9 billion. • Increased demands on our land and water resources to produce more food, more biofuels and more forest products. • Water resources are already over allocated. • Agriculture uses around 70 percent of all freshwater withdrawals worldwide and is by far the biggest consumer of both surface and groundwater. • Agriculture will face more competition from industrial, mining and urban users, putting greater pressure on achieving more efficient use of water for crop production. Environmental Impact: • Intense competition for water will mean less water for the environment. Policy Impact: • Coping with climate change • Accessing groundwater storage • Increased risk to food & water security
