This paper evaluates the effects of a public groundwater provision program on water tables in Northern India. I theorize that public provision leads to sustainable use of groundwater when the fixed costs for private well provision are high. I use village-level longitudinal data on aquifers and...

Wastewater management has been seen primarily as a technical and economic issue but it is now recognised that these are some of the elements in an array of other factors that affect sustainability of wastewater systems. Literature studies point out that municipal authorities have a general and...

This paper seeks to assess the current status of water quality trading and to identify possible problems and solutions. Water pollution permit trading programs have rarely been comprehensively described and analyzed in the peer-reviewed literature. Including active programs and completed or...

The southern regions of Alberta, Manitoba and Saskatchewan suffer from periodic drought more than any other part of Canada. They depend heavily on rivers that rise in the Rocky Mountains and traverse all three provinces to their outlet on Hudson Bay. In 1969, after a prolonged period of...

This review critically looks at the theoretical and empirical foundations of positive mathematical programming and its evolution in the past decade or so. We show how the need to model new empirical phenomena has induced the literature to rethink model specifications and to address new questions...

In the rural economy land is the site of production. Our villagers live and work with close relationship with nature; they love and adore nature. Intensification of resource use and diversification of occupation (even if we call it as technological advancement) pose serious challenges to balanced...

In this paper an attempt has been made to analyse the behaviour of Lyari River contaminated wastewater to main sea. Main focus is on the sate of water ways and physical, chemical and metallic parameters for effluents. Empirical analysis is done for the proper conclusion and implications. Lyari...

In this communication we utilize an improved version for model proposed by Manning for the waste flow via an open channel Lyari. We have computed the status of discharges, storages and depth for all locations of the Lyari waste flow using this proposed model. We have found that the result...

Water is a limiting factor for sustainable economic growth and development in many countries. Its allocation has significant impacts on overall economic efficiency, particularly with growing physical scarcity in certain regions. Water also has become a strategic resource, involving conflicts...
