About the Edition

This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity. If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller -- and environmental impacts that are greater -- than anticipated. To illustrate this possibility, this report examines environmental outcomes stemming from land use conversion caused by two agricultural programs that others have identified as potentially having important influences on land use and environmental quality: Federal crop insurance subsidies and the Conservation Reserve Program (CRP), the Nation"s largest cropland retirement program. The report finds that lands moving between cultivated cropland and less intensive agricultural uses are, on average, less productive and more vulnerable to erosion than other cultivated lands, both nationally and locally. These lands are also associated with greater potential nutrient runoff and leaching compared with cultivated cropland nationally. Crop insurance subsidies and CRP have estimated effects on erosion and other environmental factors that are disproportionate to the acreage and production effects, but specific environmental impacts vary with the features of each program.

[Ruben N Lubowski; United States. Department of Agriculture. Economic Research Service.;] -- This report examines evidence on the relationship between agricultural land-use changes, soil productivity, and indicators of environmental sensitivity.

“Land use” is the term used to describe the human use of land. It represents the economic and cultural activities (e.g., agricultural, residential, industrial, mining, and recreational uses) that are practiced at a given place.

Public and private lands frequently represent very different uses. For example, urban development seldom occurs on. Land Use Change. Land-use change is defined as greenhouse gas emissions from human activities which either change the way land is used (e.g., clearing of forests for agricultural use) or has an effect on the amount of biomass in existing biomass stocks (e.g., forests, village trees, woody savannas, etc.

If cropland that shifts in and out of production is less productive and more environmentally sensitive than other cropland, policy-induced changes in land use could have production effects that are smaller-and.

Land use change, intensive farming systems, and poor land management practices are related to reduced soil organic carbon (SOC) and soil health. One way to address these concerns is by implementing ecological principles to Environmental effects of agricultural land-use change book agroecosystems for environmental and economic benefits.

[Ruben N Lubowski; United States. Department of Agriculture. Economic Research Service.]. Southern Europe has been experiencing an accelerated intensification of agricultural systems in the last decades with consequent environmental effects.

This study aimed to evaluate the effects of agricultural land use in two small-medium river basins in the South of Portugal, regarding: (i) water quality and stream habitat; (ii) fish fauna; and (iii) : Paula Matono, Teresa Batista, Elsa Sampaio, Maria Ilhéu.

This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and.

seconds to millennia, but also slow or punctuated evolutionary changes in biota are a continuing phenomenon. Similarly, climate as well as landscape and vegetation has fluctuated greatly during the brief interval of human occupance of the earth ().Thus the impact of population numbers or of population and technological change cannot be evaluated in the absence of some knowledge.

Land cover- (plants, waters or constructed items) and land use- by humans and other creatures, change (LCLUC) is one of the great areas of interest to scientists involved in Global Change studies. Because agriculture, by nature, involves changing the land cover, it plays a large role in these studies.

USGS - Climate and Land Use Change Mission Area -The USGS is a science. Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net ± Gt carbon per year to the atmosphere.

For comparison, the major source of CO 2, namely emissions from fossil fuel combustion and. Global warming - Global warming - Land-use change: There are a number of ways in which changes in land use can influence climate. The most direct influence is through the alteration of Earth’s albedo, or surface reflectance.

For example, the replacement of forest by cropland and pasture in the middle latitudes over the past several centuries has led to an increase in albedo.

This book is a valuable resource for those working in environmental sciences, soil sciences. Goals / Objectives The primary objective of this project is to evaluate how management decisions affect agricultural production, net farm income and the natural resources upon which agriculture and the state's economy depends.

The specific objectives are: te how Federal and state agricultural and environmental policies influence management decisions of farmers and. Current intensification and changes in agricultural land use practices increase environmental impact that can be reduced by bridging the gap between socio-economic demands and scientific justification of sustainable agricultural land use.

This can be achieved by replacing the goal of maximum crop yields with the goal of minimal environmental. ‘ as a review of the state of knowledge and research on the subject, particularly concerning the agricultural consequences of climate change, it is highly recommended.’ – Clive Potter, Environment Global Environmental Change and Agriculture offers a.

With regard to the land use issue, this means that an average of about 20% of the agricultural land of the Alps has been abandoned, and in some areas as much as 70% (Tappeiner et al.

in press). In contrast, farming in the better agricultural locations is being by: Land­use and land­cover change (LULCC); also known as land change) is apparent changes in land cover, similar effects are observed whenever relatively undisturbed lands are reducing the suitability of land for future agricultural use, but also releases huge quantities of phosphorus, nitrogen, and sediments to streams and other aquatic File Size: KB.

Indirect land use change takes place when a direct change in land use in one location, is causally connected to a corresponding change in land use in another location. The causal mechanism behind this shift in land use from one location to another is the influence of agricultural markets on regional or global land use.

Department of Agriculture’s Conservation Effects. Although bioenergy is a renewable energy source, it is not without impact on the environment. Both the cultivation of crops specifically for use as biofuels and the use of agricultural byproducts to generate energy changes the landscape, affects ecosystems, and impacts the climate.

Bioenergy and Land Use Change focuses on regional and global assessments of land use. Land Use and Cover Change (LUCC), especially, Agricultural Land Use Change (ALC) as a result of human activities over the past 50 years, is converted to a main challenge of 21 century.

change – which are closely linked to food and energy price spikes and volatility – have raised concerns on the impact of LUCC change on biodiversity and other environmental impacts.

Additionally, LUCC change could lead to natural resource degradation – which affect the poor the most since they heavily depend on natural resources. To refine our measurement of the environmental impact we have undertaken a new series of analyses (Burke et al., ; Parton et al., in press; Cunfer, Cunfer, ) that make use of the history of nineteenth- and twentieth-century land use change to estimate the impact of population-induced agricultural land use on soil biogeochemistry Cited by: 9.

Apart from the known effects of urbanization on global warming, acid rain and ozone depletion, it is also. The project is particularly strong in documenting the effects of land use change on the environment, for instance, the consequences of agricultural intensification in the form of increasing fertilizer inputs for the functioning of both the surface water systems draining the valley and for the coastal ecosystems of the Sea of Cortez.

As time passed, agriculture became the most dominant land use on the planet, feeding a booming population and transforming natural habitats of many species. Whether the outcome of this change delivers negative or positive consequences depends largely on.

The dynamic bibliography on Modeling and Water Resources may also have information relevant to targeting conservation. This study develops a methodology for quantifying the impact of land use and climate change and therefore contributes to the sustainable management of the investigated catchment, as it shows the impact of environmental change on hydrological extremes (low flow and floods) and determines hot spots, which are critical for environmental development.

Introduction. In addition to emissions of heat-trapping greenhouse gases from energy, industrial, agricultural, and other activities, humans also affect climate through changes in land use (activities taking place on land, like growing food, cutting trees, or building cities) and land cover (the physical characteristics of the land surface, including grain crops, trees, or concrete).
