Rangeland ecosystem services: shifting focus from supply to reconciling supply and demand

Journal Articles & Books
Diciembre, 2015

Ecosystem services have been extensively studied in terms of their production, spatial extent, and valuation. Human reliance on ecosystem services is a function of the capacity of ecosystems to supply these services and the societal demand for these benefits. Considerably more attention has been placed on the supply of services compared with their demand. Sustainable land management depends on reconciling supply of and demand for ecosystem services among different stakeholders. The emphasis is now shifting from the supply to the attaining of a balance between supply and demand.

Analysis of Rural Landscape and Land Fragmentation Through GIS in the Gjocaj Commune, Albania

Albania

After the downfall of the socialist economic system in 1990, Albania underwent an agriculture reform in 1992. After the reform execution, all agricultural land was redistributed among village residents. The subsequent land segmentation lead to extreme agriculture production implications.Gjocaj Commune is located in the centre of Albania at the Peqin District part of the Elbasan Region, which is a typical agricultural area, very close to Tirana and not far from the Adriatic seashore.

impact of livestock grazing management systems on soil and vegetation characteristics across savanna ecosystems in Botswana

Botswana

The objective of this study was to determine the impact of livestock grazing management systems on soil and vegetation dynamics under different environmental conditions of Botswana. Soil and vegetation were randomly sampled along transects located in three ranches and adjacent communal grazing land in 2009 and 2010. Our results showed that grazing management systems did not consistently affect soil texture, organic carbon, pH and bulk density.

COST action ES1104 “Arid lands restoration and combat of desertification: Setting up a drylands and desert restoration hub”

Europa

This paper briefly describes COST Action ES1104 “Arid lands restoration and combat of desertification: Setting up a drylands and desert restoration hub”. (COST - European Cooperation in Science and Technology) is one of the longest running European frameworks supporting cooperation among scientists and researchers across Europe.) This networking project’s focus is to provide a hub of knowledge particularly relating to the practical methods of vegetation establishment and restoration as well as sustainable land management in arid and dryland areas.

Simulation of land use/land cover change and its effects on the hydrological characteristics of the upper reaches of the Hanjiang Basin

Journal Articles & Books
Diciembre, 2015

In any watershed, many factors influence land use/cover change (LUCC). The nonlinear relationships between these factors and LUCC are very complicated and make it difficult to build a model that is capable of accurately simulating the range of physical processes. The aim of this study was: (1) to simplify the structure of a simulation model and improve its simulation speed, and (2) evaluate the impact of land use/cover change on surface runoff and evapotranspiration.

Effects of improved management and quality of farmyard manure on soil organic carbon contents in small-holder farming systems of the Middle Hills of Nepal

Nepal

Simple and widely adopted sustainable soil management (SSM) practices, especially improvements in the management and quality of farmyard manure (FYM), have enabled many thousands of small-scale farmers in the Middle Hills of Nepal to increase organic matter in their soils. This has been achieved without increases in livestock numbers or in the quantity of manure available. The organic matter contents have increased in all of five time series of on-farm topsoil monitoring over periods of one to three years, at rates varying from 2% to 27%.

Assessment of land degradation and its impact on crop production in the Dry Zone of Myanmar

Journal Articles & Books
Diciembre, 2015
Myanmar

Land degradation in terms of soil degradation is a major environmental issue posing threat to sustainable livelihood in the semi-arid region of Central Myanmar. However, the studies on soil degradation status and its impacts in this region are very scanty. The objective of this study was to determine the impact of land degradation on crop production both in terms of area and yield in the Dry Zone of Myanmar. Remote sensing and geographic information system-based modelling was utilized to assess and map soil erosion rates.

Spatio‐Temporal Patterns of Land Use/Cover Changes Over the Past 20 Years in the Middle Reaches of the Tarim River, Xinjiang, China

China

The interaction between land use/cover change and landscape pattern is pivotal in research concerning global environmental change. This study uses three different Landsat images of 1989, 1998 and 2009 to study the land use/cover and landscape pattern changes in the middle reaches of the Tarim River basin. envi®, erdas®, ArcGIS® and fragstats® software were used to analyse the land use/cover changes. The objectives of study were to map and study the changes in land use/cover and landscape pattern, and propose some possible factors in making the land use/cover changes from 1989 to 2009.

Land-use/land cover changes and their driving forces around wetlands in Shangri-La County, Yunnan Province, China

Journal Articles & Books

China

The Shangri-La County of the Yunnan Province, SW China, is an economically and ecologically important area. This is especially true for Jiantang that is famous for the Napahai, Bitahai and Shudu Lake wetlands. However, continuing development has threatened the wetland ecosystems and the associated biodiversity in these areas. To better document such changes in land use and their effect on the ecosystem, land use was mapped using a time series of satellite images acquired in 1974, 1993, 2000 and 2012. The results of this survey suggest that forest cover first decreased and then increased.

Expanding sustainable land management in Ethiopia: scenarios for improved agricultural water management in the Blue Nile

Journal Articles & Books
Diciembre, 2015

Deforestation due to farmland expansion, fragile soils, undulating terrain, and heavy seasonal rains makes the highlands of Ethiopia vulnerable to soil erosion. The diverse terrain of the rural highlands requires spatially explicit investments in land management structures. This paper utilizes recent hydrological and meteorological data collected from the Mizewa watershed in the Blue Nile Basin of Ethiopia, as well as household survey data on farmer preferences and investments, in order to better understand the physical impact of sustainable land management activities.
