Integration of MultiCriteria Decision Analysis in GIS to develop land suitability for agriculture: Application to durum wheat cultivation in the region of Mleta in Algeria

Journal Articles & Books
Dezembro, 2012
Argélia

Due to constant decrease in farmlands, it is important to identify the best lands useful for sustainable agriculture (productive and profitable agriculture that protects the environment and that is socially equitable). This requirement has resulted in the development of land suitability maps for agriculture by combining several factors of various natures and of differing importance.

review of forest and tree plantation biomass equations in Indonesia

Dezembro, 2015
Indonésia

KEY MESSAGE : We compiled 2,458 biomass equations from 168 destructive sampling studies in Indonesia. Unpublished academic theses contributed the largest share of the biomass equations. The availability of the biomass equations was skewed to certain regions, forest types, and species. Further research is necessary to fill the data gaps in emission factors and to enhance the implementation of climate change mitigation projects and programs.

Assessing the application of a geographic presence-only model for land suitability mapping

Journal Articles & Books
Dezembro, 2011
Tailândia

Recent advances in ecological modeling have focused on novel methods for characterizing the environment that use presence-only data and machine-learning algorithms to predict the likelihood of species occurrence. These novel methods may have great potential for land suitability applications in the developing world where detailed land cover information is often unavailable or incomplete.

Land use and land cover classification over a large area in Iran based on single date analysis of satellite imagery

Irã

Accelerated soil erosion, high sediment yields, floods and debris flow are serious problems in many areas of Iran, and in particular in the Golestan dam watershed, which is the area that was investigated in this study. Accurate land use and land cover (LULC) maps can be effective tools to help soil erosion control efforts.

Cost-effectiveness and cost-benefit analysis of BMPs in controlling agricultural nonpoint source pollution in China based on the SWAT model

Journal Articles & Books
Dezembro, 2014
China

Best management practices (BMPs) have been widely used in managing agricultural nonpoint source pollution (ANSP) at the watershed level. Most BMPs are related to land use, tillage management, and fertilizer levels. In total, seven BMP scenarios (Reforest1, Reforest2, No Tillage, Contour tillage, and fertilizer level 1–4) that are related to these three factors were estimated in this study.

Evaluation of land use/land cover changes in Mekelle City, Ethiopia using Remote Sensing and GIS

Land use is a dynamic phenomenon that changes with time and space due to anthropogenic pressure and development. Evaluating the existing land use and its periodic change is useful for urban planners, policy makers and natural resource managers. Land use and land cover changes in Mekelle City, Ethiopia (north east Africa) over a period of 25 years was studied using remotely sensed data. Multi temporal satellite data of Landsat was used to map and monitor urban land use changes occurred during two point of time of 1985 and 2010.

Spatial assessment of soil erosion risk using RUSLE and GIS techniques

Journal Articles & Books
Dezembro, 2015
Jordânia

Soil erosion by water is considered a major cause for land degradation in Jordan, where 0.14 cm of productive top soil is eroded annually. This investigation is intended to estimate the annual soil loss in Wadi Kerak watershed, and to examine the spatial patterns of soil loss and intensity, as an essential procedure for proper planning of conservation measures. To achieve these objectives, the revised universal soil loss equation (RUSLE) model has been applied in a geographical information system framework.

influence of land use patterns on water quality at multiple spatial scales in a river system

Journal Articles & Books
Dezembro, 2014
China

The influence of land use patterns on water quality in a river system is scale‐dependent. In this study, a four‐order hierarchical arrangement method was used to select water sampling sites and to delineate sub‐basins in the Daliao River Basin, China. The 20 sub‐basins were classified into four spatial scales that represented four different stream orders. Pearson correlation analysis was used to quantify relationships between land use composition and the river's physical‐chemical variables for all samples collected.

Land-cover and land-use change and its contribution to the large-scale organization of Puerto Rico's bird assemblages

Global biodiversity is changing rapidly driven by human alteration of habitat, and nowhere this is more dramatic than in insular habitats. Yet land-cover change is a complex phenomenon that not only involves habitat destruction but also forest recovery over different time scales. Therefore, we might expect species to respond in diverse ways with likely consequences for the reorganization of regional assemblages. These changes, however, may be different in tropical islands because of their low species richness, generalist habits and high proportion of endemics.

Estimating the Implicit Value of Crop Stubble as a Barrier to Technology Adoption in Morocco

Conference Papers & Reports
Dezembro, 2010
Marrocos

For mixed cereal-livestock farmers, cereal production provides a bundle of goods.Grain is consumed by the household or sold at market, and crop residues are used aslivestock feed. The straw component of crop residue can be bought and sold at market andtherefore has a well-established local market price. Crop stubble, the portion of the crop residue left on the ground, is generally not traded and therefore has no market price.

When should households be compensated for land-use restrictions? A decision-making framework for Chinese forest policy

Journal Articles & Books
Dezembro, 2011
China

Competing uses of land mean that regulations aimed at environmental conservation often conflict with the land-use rights of rural households. Several reports suggest that this has occurred with the introduction of the Natural Forest Protection Programme (NFPP) in China, one of the world's largest logging ban programmes. This paper investigates whether households should be compensated for infringements on property rights, drawing on institutional economics literature on regulation.

systematic review of built environment factors related to physical activity and obesity risk: implications for smart growth urban planning

Journal Articles & Books
Dezembro, 2011

Smart growth is an approach to urban planning that provides a framework for making community development decisions. Despite its growing use, it is not known whether smart growth can impact physical activity. This review utilizes existing built environment research on factors that have been used in smart growth planning to determine whether they are associated with physical activity or body mass.
