The environmental impact of agriculture cannot be ignored. In many countries, as much as 70 per cent of the land area is in agricultural use. Over a third of the global agricultural land area is in high-intensity, continuous cropping systems that use high levels of agrochemicals and reshape land and waterways. The rest is under such a farming system that uses far fewer inputs, but requires rela...

Land Use patterns reflect the nature of economic activity as well as natural resources of a country. The evaluation and assessment of land uses leads to diagnose the patterns of resources of a country which can further be developed in order to gain and maintain self sufficiency in the resources needed for human and economic development. The monitoring of land use change is highly difficult and ...

Land provides a host of ecosystem services, of which the provisioning services are often considered paramount. As the demand for agricultural products multiplies, other ecosystem services are being degraded or lost entirely. Finding a sustainable trade-off between food production and one or more of other ecosystem services, given the variety of stakeholders, is a matter of optimizing land use i...

With growing demand and highly variable inter-annual water supplies, California's water use future is fraught with uncertainty. Climate change projections, anticipated population growth, and continued agricultural intensification, will likely stress existing water supplies in coming decades. Using a state-and-transition simulation modeling approach, we examine a broad suite of spatially explici...

the kind of land use and intensity of its change is considered as important desertification indices in different models. land use change is one of the main anthropogenic factors in the desertification. the current research was carried out around imam khomeini airport, with an area of 32000 km2, in order to evaluate mentioned area's land use changes effects during 1955-2003 on desertification. t...

Increasing rates of water extraction and regulation of hydrologic processes, coupled with destruction of natural vegetation, pollution and climate change, are jeopardizing the future persistence of wetlands and the ecological and socio-economic functions they support. Globally, it is estimated that 50% of wetlands have been lost since the 1900’s, with agricultural changes being the main cause. ...

The use of satellite technology by military planners has a relatively long history as a tool of warfare, but little research has used satellite technology to study the effects of war. This research addresses this gap by applying satellite remote sensing imagery to study the effects of war on land-use/land-cover change in northeast Bosnia. Though the most severe war impacts are visible at local ...

The Brazilian Amazon is one of the most rapidly developing agricultural areas in the world and represents a potentially large future source of greenhouse gases from land clearing and subsequent agricultural management. In an integrated approach, we estimate the greenhouse gas dynamics of natural ecosystems and agricultural ecosystems after clearing in the context of a future climate. We examine...
