This paper modifies and uses an advanced computable general equilibrium model coupled with biophysical data on land and water resources by agro-ecological zone at the river basin level to examine the economy-wide consequences of improvements in water use efficiency (WUE) in irrigation in South Asia. This is the first time the benefits of such...

Water is one of the enablers for achieving the Sustainable Development Goals (SDGs) and the Paris Climate Agreement goals, especially on adaption. However, global water resources are under increasing pressure due to the growing gap between water supply and demand, wasteful use of water, anthropogenic water pollution, lack of integration in sectoral...

Water and energy are two fundamental elements for achieving sustainable development in South Asia, a region facing many challenges of achieving the sustainable development goals under resource constraints. Water and energy are inherently inter‐dependent which requires a nexus perspective to address their synergy. However, sectoral approaches have...

This working paper assesses the groundwater-WASH (Water, Sanitation and Hygiene) nexus based on an analysis of domestic water uses in three groundwater dependent Asian Cities: Hanoi (Viet Nam), Kathmandu (Nepal), and Khulna (Bangladesh). The paper analyses the pull (benefits) and push (constraints) factors for use of groundwater by residents in...

Groundwater contributes to the sustainable development of many Asian cities by providing water for domestic, industrial, and agricultural uses and by regulating ecosystem flows. In many Asian cities more than half the potable water supply comes from groundwater. In some cities, groundwater abstraction for industrial use is even higher than for...

Groundwater is the sole source of water supply in Khulna. It is abstracted both by municipality and privately. Furthermore, it is an important source of irrigation at the outskirts of the city and an important source of water supply during disasters that occur quite frequently. Despite the easy availability of groundwater, Khulna is facing acute...

Groundwater has been a traditional source of water supply in Japan for a long period of time. After the country entered a rapid phase of industrialization and urbanization, there was an obvious increase in the pressures on the groundwater environment. Uncontrolled abstraction of groundwater soon led to the emergence of problems such as drawdown of...
