Efficient use of assets in agriculture is a goal for policy-makers and farmers. Agricultural input resources are scarce therefore optimum use of inputs in different agricultural operations is important. Mathematical programming technique such as data envelopment analysis (DEA) is a well-known approach for estimation efficiency of agricultural DMUs. In this study, efficiency of kidney bean produ...

extended abstract 1. introduction land as habitat and place of having the highest importance in human life and the source of all human needs is. any planning requires having information about the phenomena on the land, trappings and paraphernalia land. this information collected is an issue that eventually will lead to the management of land information in one system. organization and operation...

Functioning ecosystems offer multiple services for human well-being (e.g., food, freshwater, fiber). Agriculture provides several of these services but also can cause negative impacts. Thus, it is essential to derive up-to-date information about agricultural land use and its change. This paper describes the multi-temporal classification of agricultural land use based on high resolution spotligh...

Blackbird Creek, Delaware is a small watershed in northern Delaware that has a significant proportion of land designated for agricultural land use. The Blackbird Creek water monitoring program was initiated in 2012 to assess the condition of the watershed’s habitats using multiple measures of water quality. Habitats were identified based on percent adjacent agricultural land use. Study sites va...

in the recent years, human activities have led to changes in land use and land cover, consequently, these changes lead to the structure and function of ecosystems. spatial-temporal change detection of land use is important to understand the relationships and interactions between human and natural resources and to make appropriate decisions due to changes in land use and land cover occurs in bro...

This paper develops an integrated framework to analyze the effects of agricultural land use change drivers (market prices, policy, climate, etc.) upon the ecological quality of rivers. Our approach integrates a land use model with a model of river biology. The agricultural model encompasses land use areas, input application, crop yields and livestock stocking rate equations in a joint econometr...

Improper land use is one major cause of non-point source pollution. Integrated modeling would support the evaluation and optimization of land use for the non-point source pollution control. In this study, the CLUE-S (the Conversion of Land Use and its Effect at Small regional extent) and SWAT (Soil and Water Assessment Tool) models were coupled to simulate pollution loads under different land u...

Increase in CO2 emissions induced by agricultural inputs in China since its socialist market economic reforms may hinder its sustainable economic development. More attention has been paid to changes in agricultural land use and overall land use benefit; however, relatively less attention has been paid to changes in CO2 emissions induced by agricultural inputs in China since the reforms. The car...

Land use planning is systematic assessment of land and water potential. Its purpose is to select and put into practice those land uses, that will best meet the need of the people while safe guarding resources for the future. Number of researchers have been established the applicability of Remote sensing and Geographical Information system to solve problems in agricultural related to land use pl...
