Progress towards sustainability demands recognizing nonlinear, time delayed interactions that are at the heart of dynamic integrated socioeconomic and biophysical systems. Sustainability and land change science communities have recognized the need to go beyond static and vague depictions of nonlinear feedback processes in the study of these integrated systems. But to date, there have been few a...

Land use/cover change (LUCC) is becoming more and frequent extensive as a result of human activities, expected to have major impact on welfare by altering ecosystem service value (ESV). In this study, we utilized remote sensing images statistical data explore the spatial-temporal changes land types ESV in northern slope economic belt Tianshan Mountains Xinjiang Uygur Autonomous Region, China fr...

To investigate land use changes, Qale Shahrokh basin (15098.1 ha area) was selected. Satellite images of Landsat sensors (MSS, TM and ETM+) were used. After improvement and different enhancement analysis of images such as FCC, PCA, the study area was checked using GPS and topographic maps (1:50000) and other information. Land use units were determined using classified random sampling method. Ma...

1 Summary This project aims to understand and model the social processes that contribute to large-scale deforestation in Amazonia. Biomass burning emissions associated with deforestation in the region are responsible for 74% of Brazil's greenhouse gas emissions and have an impact on global environmental changes. We argue that land changes in Amazonia are brought about by social and institutiona...

Accurate assessment and response analysis of land use cover change (LUCC), ecosystem service values (ESV), are critical to regional ecological security economic development. There is a lack detailed reports on the impact LUCC temporal spatial evolution ESV in Yinchuan City, which inconsistent with pilot urban design policy. This paper, using data City from 1980 2018, calculated ESV, analyzed pa...
