Economic Impacts of the Trend toward Monoculture in Agriculture

Introduction

Population and financial development in evolving countries posed serious challenges for humanity in simultaneously gathering nourishment requirements and water demands. Competition for restricted water resources increasingly occurs between distinct stakeholders and at distinct levels: between farmers inside an irrigation system; between irrigation systems in the same stream basin; between the agricultural sector and other rural uses, such as fisheries or domestic water supply and consuming water; and more and more between agricultural and urban and industrial users and uses; and environmental uses. Agriculture still accounts for the majority of global water withdrawals, and is often responsible for 65% or more of total withdrawals for consumptive uses in America.

Economic impacts of reduced water supply for irrigation

Only a restricted number of studies have assessed the impacts of climate change on irrigated agriculture in a manner that specifically recognizes the water balance between climate change, the hydrology of the system, and water allocation to irrigated agriculture. Globally, increased rainfall is forecast, but reductions in rainfall are projected for some parts of the world, .Gleick and Chalecki (1999) evaluate the impact of climate change on two major U.S. rivers—the Colorado and the Sacramento-San Joaquin. They resolve that global warming will most probable cause a shift away from spring and summer run-off toward more winter run-off with probable consequences encompassing decreased irrigation water availability.

The main target of addressing the labour issue in this case study is to work out the main socio-economic impacts of irrigation decrease on the main communities located in the Northern America Valley, as the expansion of the cultivated area leads to a significant increase in output intensity and effectiveness thus, the result will create a better output opportunities, more jobs requires more labour, which means increasing the capability of the persons to satisfy their needs and to relish a better quality of life.

The decrease in the decrease in water supply decreased the cultivated area accordingly; the direct impact of this decrease will have adverse affects on the development in new jobs in the NJV communities, which may drag workers and their families out of their communities, either those permanent or temporary residents. When this occurs the outgoing population affects the social natural environment in various ways encompassing smaller demand for housing and social services (e.g., health care, education, recreational facilities). However, a more severe impact will take place in cases of 50% decrease which correspond to the maximum grade of decrease in irrigation water supply. The loss in chartered and family labour is about 33% respectively, increasing the amount of water supply will encourage the investment in irrigated agriculture that would accelerate the development rate of the agricultural sector and decrease the job loss percentage in the area, and new jobs will be open and available. On the other hand, an increase of 20% in water supply the chartered labour increased by about 18 % ...
