Agro-ecological field vulnerability evaluation and climate change impacts in Souma area (Iran), using MicroLEIS DSS
Soil erosion and contamination are two main desertification indices or land degradation agents in agricultural areas. Global climate change consequence is a priority to predict global environmental change impacts on these degradation risks. This agro-ecological approach can be especially useful when formulating soil specific agricultural practices based on the spatial variability of soils and related resources to reverse environmental degradation.
Mapping ecosystem service supply, demand and budgets
Among the main effects of human activities on the environment are land use and resulting land cover changes. Such changes impact the capacity of ecosystems to provide goods and services to the human society. This supply of multiple goods and services by nature should match the demands of the society, if self-sustaining human–environmental systems and a sustainable utilization of natural capital are to be achieved. To describe respective states and dynamics, appropriate indicators and data for their quantification, including quantitative and qualitative assessments, are needed.
How Attitudes are Shaped: Controversies Surrounding Red Deer Management in a National Park
Attitude surveys among affected groups are established tools for integrating actors into decision-making concerning wildlife management. However, the complexity of attitudes and the fact that general attitudes toward wildlife may differ from those toward specific management measures reveal the risk of misinterpreting the data obtained. This article explores these problems based on a quantitative survey of hunters and landowners living close to the Bavarian Forest National Park, Germany.
Land Use and Cover Dynamics Since 1964 in the Afro‐Alpine Vegetation Belt: Lib Amba Mountain in North Ethiopia
Human‐induced land use and land cover (LUC) changes threaten the ecosystem services of the vulnerable tropical afro‐alpine vegetation. Several LUC change studies are available for the Ethiopian highlands, but relatively little is known about LUC change in the afro‐alpine zones. In this study, LUC changes between 1964 and 2012 were mapped for the afro‐alpine zone of Lib Amba Mountain, part of the Abune Yosef Mountains in North Ethiopia. Historical LUC was derived from georeferenced aerial photographs of 1964 and 1982, and the present LUC (2012) from Bing Map satellite imagery.
Geospatial comparison of four models to predict soil erodibility in a semi-arid region of Central India
The soil erodibility factor of RUSLE is one of the important indicators of land degradation. It can be measured either directly under natural or simulated rainfall condition or indirectly estimated by empirical models. A geospatial variation of this factor is essential for prioritization of reclamation measures. However, geospatial upscaling of soil erodibility factor is very uncertain because of its dynamic nature and dependent on the parameters used in the model.
Controls of land use and soil structure on water movement: Lessons for pollutant transfer through the unsaturated zone
To address the effects of land use and land cover (LULC) on soil structure formation and the significance on preferential flow during infiltration, dye tracer experiments were conducted on five sites differing in LULC, yet displaying similar soil textural characteristics and parent material. Two grassland sites, two farmland sites (tilled and untilled) and one site located in a deciduous forest were investigated. At each site, the same sprinkling experiment was carried out with a Brilliant Blue FCF solution of 4gL⁻¹ to visualize flow paths.
Why are there so few cooperative agreements between farmers and water services in france? water policies and the problem of land use rights
One of the recurrent shortcomings of water policy in France is the control of diffuse agricultural pollution. Numerous lacunae and incoherencies in the French Rural, Public Health, and Environmental Codes have hindered the effective implementation of efficient protection measures. In this paper, we underline the extent to which these incoherencies have hampered the emergence of cooperative agreements (CAs) between farmers and drinking water service providers.
Analysis of deforestation patterns in the Baekdudaegan preservation area using land cover classification and change detection techniques; the feasibility of restoration
The Baekdudaegan Mountain Range is a backbone of the Korean Peninsula which has special spiritual and sentimental significance for Koreans and significant ecological value to diverse organisms. Despite the importance of this region, however, the natural environment of Baekdudaegan has been severely threatened by a variety of human activity and tremendous forest fires. To make management and restoration plans for the deforested areas, it is necessary to investigate quantitatively such natural and human-induced physical changes.
Integration of land use and land cover inventories for landscape management and planning in Italy
There are both semantic and technical differences between land use (LU) and land cover (LC) measurements. In cartographic approaches, these differences are often neglected, giving rise to a hybrid classification. The aim of this paper is to provide a better understanding and characterization of the two classification schemes using a comparison that allows maximization of the informative power of both. The analysis was carried out in the Molise region (Central Italy) using sample information from the Italian Land Use Inventory (IUTI).
Impacts of landscape fragmentation on simulated precipitation fields in the Amazonian sub-basin of Ji-Paraná using the Eta model
Numerical studies on impacts of landscape fragmentation due to land use and land cover change (LUCC) on precipitation fields over the Ji-Paraná basin in the Amazon region are carried out using atmospheric Eta model. Experiments consider historical data about LUCC over the basin from 1978 to 2000 and compare simulations under LUCC conditions with simulations under pristine conditions. In agreement with previous observational studies, model results do not show statistically significant impacts on precipitation in the region.
Monitoring urban expansion and its effects on land use and land cover changes in Guangzhou city, China
There are widespread concerns about urban sprawl in China. In response, modeling and assessing urban expansion and subsequent land use and land cover (LULC) changes have become important approaches to support decisions about appropriate development and land resource use. Guangzhou, a major metropolitan city in South China, has experienced rapid urbanization and great economic growth in the past few decades. This study applied a series of Landsat images to assess the urban expansion and subsequent LULC changes over 35 years, from 1979 to 2013.
