A major challenge in gauging long-term and cumulative impacts of fisheries management on coastal fishing communities is the lack of understanding of the interactions between changes in fish stocks and waterfront land uses. This study examines these interactions in the New Bedford/Fairhaven area using parcel level data and geographic information system (GIS) tools. Logistic regression models wer...
Evaluation of chemical and biological indicators of soil in different land uses could be helpful in sustainable range management, preventing degradation of soil quality trend. This study was conducted in Friedan in Isfahan province in 2010 to compare chemical and biological indicators in three land uses (rangeland, degraded dry land and dry land), during two growing seasons (May and September) ...
In this study, we analyze the effect of property taxes on changes between agricultural, forestry, Conservation Reserve Program, and developed land uses in Louisiana. We estimate a random parameters logit model of land-use conversion from the National Resources Inventory plot data. Our results indicate that land-use changes are inelastic with respect to property taxes. Simulation shows that curr...
Land use change alters the structure and composition of microbial communities. However, the links between environmental factors and microbial functions are not well understood. Here we interrogated the functional structure of soil microbial communities across different land uses. In a multivariate regression tree analysis of soil physicochemical properties and genes detected by functional micro...
The area of Huelva, in the South of Spain, is a well-known case of human pressure on the natural environment. In Huelva, National Parks, like Doñana, and industrial and tourist zones coexist in difficult balance. The Regional Ministry of Andalusia is commissioned to assure the preservation of the natural resources in this part of Spain although its cost can be high in time and money. Remote sen...
Restoration of the degraded ecosystem is a global priority for achieving sustainable development. Although increasing ecosystem service is an important goal of ecological restoration, it is rarely used to inform mine reclamation. This study proposed a reclamation strategy that incorporated land suitability analysis and ecosystem service evaluation for a mining site in Liaoning Province, China. ...
Land-use changes involve important economic and environmental effects with implications for international trade, global climate change, wildlife, and other policy issues. We use an econometric model to identify factors driving land-use change in the United States between 1982 and 1997. We quantify the effects of net returns to alternative land uses on private landowners’ decisions to allocate l...
The global land system is under intense pressure from human demands for a range of different services. Economic theory suggests that globalised free trade is the most efficient way of handling these demands, allowing maximum productivity and specialisation of supply. However, political responses are often protectionist in nature, designed to ensure continuity of land uses and the regional produ...
Landscape Development Intensity (LDI) values were calculated for selected land uses within the Bayou Meto Watershed (BMW), Arkansas, USA, using existing land use data and annual measures of non-renewable energy use per unit area, as part of an effort to assess the effect of the surrounding land use on the condition of floodplain forested wetlands. Level 2 land use categories from the 1999 Arkan...
The vertical distribution of dominant genera of bacterivorous nematodes to 150-cm depth in an aquic brown soil was compared after 14 years of four contrasting land uses, i.e., cropland-rice (CR), cropland-maize (CM), abandoned cropland (AC), and woodland (WL). The study was conducted at the Shenyang Experimental Station of Ecology, a Chinese Ecosystem Research Network (CERN) site in Northeast C...
