Agricultural sectors play a key role in the economics of climate change. Land as an input to agricultural production is one of the most important links between economy and the biosphere, representing a direct projection of human action on the natural environment. Agricultural management practices and cropping patterns have a vast effect on biogeochemical cycles, freshwater availability and soil quality. Agriculture also plays an important role in emitting and storing greenhouse gases.

Because of the logics of both colonization or de-colonization, the need to counter the anarchy of groundwater use, or the dissemination of global 'best practices' of IWRM, states have often assumed full ownership or custody of groundwater. Regulating groundwater use includes giving drilling and abstraction authorizations/licenses, establishing an inventory of wells and reducing use in existing wells.

Resource structure in the observed countries, who belong to different agriculture types expressed through relationship land/work ratio, indicates significant variations. Different resource supply is crucial in determining the level of productivity of labor and land in agriculture, and therefore, affects the competitiveness of agriculture, the competitiveness of an entire national economy as well.

A study was conducted in Sargodha, Pakistan during the year 2011 to testify irrigation practices as a method for reclaiming salt affected soil. Field experiments were conducted on saline-sodic and uncultivated land divided into 12 field plots. Six irrigation treatments, each replicated on two field plots, were applied to test the responses of soil and wheat crop yield.

Although advances in remote sensing have enhanced mapping and monitoring of irrigated areas, producing accurate cropping information through satellite image classification remains elusive due to the complexity of landscapes, changes in reflectance of different land-covers, the remote sensing data selected, and image processing methods used, among others. This study extracted agricultural fields in the former homelands of Venda and Gazankulu in Limpopo Province, South Africa.

In this paper we study the interplay between residential location choice, sprawl and water quality. We propose an urban economics model of a, first, monocentric, then, polycentric city with two di erent residential areas : sewer-serviced suburbia, with small residential lot size, and exurbia where wastewater management is individual and on-site and residential lots are larger to accomodate sanitary requirements. Sewer and septic are also characterized by di erent abatement e ciencies.
