Although increasing population in Turkey agricultural lands have not been expanded, thus, agricultural lands should be used more effectively. Therefore, Land consolidation is the most important work, which has to be done. Land consolidation takes time to execute project because of large application area and extensive. Therefore, using computer is extremely significant to conclude the land conso...

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 ...

Due to inappropriate planning and management, accelerated urban growth and tremendous loss in land, especially cropland, have become a great challenge for sustainable urban development [1]. Detection of such changes may help decision makers and planners to understand the factors in land use and land cover changes in order to take effective and useful measures. Remote sensing and GIS techniques ...

Secondary forest succession on abandoned agricultural land has played a significant role in land cover changes in Europe over the past several decades. However, it is difficult to quantify over large areas. In this paper, we present a conceptual framework for mapping forest succession patterns using vegetation structure information derived from LiDAR data supported by national topographic vecto...

Malawi has exceptionally high rates of population growth (3.1%) and deforestation (2.4%), suggesting a Malthusian link between the two. The most important proximal cause of forest loss in Malawi has been the expansion of agricultural land. Population growth has been an important driver for this process, but is an insufficient explanation by itself. In Malawi’s case, it has been coupled with a l...

A proactive sampling strategy was designed and implemented in 2000 to document changes in streams whose catchment land uses were predicted to change over the next two decades due to increased building density. Diatoms, macroinvertebrates, fishes, suspended sediment, dissolved solids, and bed composition were measured at two reference sites and six sites where a socioeconomic model suggested new...

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...

Understanding the processes of historical land-use change is crucial to the research of global environmental sustainability. Here we examine and attempt to disentangle the evolutionary interactions between land-use change and its underlying causes through a historical lens. We compiled and synthesized historical land-use change and various biophysical, political, socioeconomic, and technical da...

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 pre-reform period was characterized by state monopoly of land and by land use that did not require any payment. The legal principles of land reform in Russia and the rest of the former Soviet Union were set in 1989 by the Basic Law on Land Legislation in the USSR and the Soviet Republics. This law established the right of the citizens to receive land in permanent or temporary use for agricu...
