The Central Asian countries are particularly affected by the global climate change. The cultural and economic centers in this mostly arid region have to rely solely on the water resources provided by the rapidly melting glaciers in the Pamir, Tien-Shan and Alay mountains. By 2030, the available water resources will be 30 % lower than today while the water demand will increase by 30 %. The unsustainable land and water use leads to a water deficit and a deterioration of the water quality.

Land selection for cultivation of sugar beet in Slovakia

Policy Papers & Briefs
Août, 2013
Slovaquie

The article aims to analyze suitability of land selection for cultivation of sugar beet in Slovakia in the period from 2008 to 2012. The results confirmed, that there are enough soils suitable for sugar beet growing in Slovakia. The area of sugar beet cultivation is conditioned by the presence of only two sugar rafineries, which are in operation, in Sered and Trencianska Tepla. The most productive soils in the climatically most suitable areas of Slovakia are chosen for growing sugar beet.

South Dakota Agricultural Land Market Trends 1991-2011: The 2011 SDSU South Dakota Farm Real Estate Survey

Reports & Research
Juin, 2011

Agricultural land values and cash rental rates in South Dakota, by region and by state, are primary topics of this report. The target audience are farmers and ranchers, landowners, ag professionals (lenders, rural appraisers, professional farm managers), and policy makers interested in ag land market trends. This report contains results of the 2011 Farm Real Estate Market Survey, the 21st annual SDSU survey developed to estimate ag land values and cash rental rates by land use in different regions of South Dakota.

Grazing as a post-mining land use: A conceptual model of the risk factors

Journal Articles & Books

Driven principally by government regulation and societal expectations, mining companies around the world are seeking to mitigate the environmental impacts of mining through mined land rehabilitation programs. The ultimate goal of rehabilitation is to establish an acceptable and sustainable post-mining land use. Mining companies worldwide face the challenge of specifying just what a sustainable post-mining land use will be.

myth of encroachment

Scholars of pastoralism often refer to changes of pastoral land tenure as ‘encroachment.’ The New Zealand case of pastoral land tenure reform suggests that this is incorrect for several reasons. First it takes the point of view of the pastoralist, which introduces unnecessary bias. Second, it assumes that all changes in land tenure are situations in which the state, or another powerful agent, takes land away from the less powerful pastoralists.

Integrated approach for understanding spatio-temporal changes in forest resource distribution in the central Himalaya

Journal Articles & Books
Décembre, 2014

Intense anthropogenic exploitation has altered distribution of forest resources. This change was analyzed using visual interpretation of satellite data of 1979, 1999 and 2009. Field and interactive social surveys were conducted to identify spatial trends in forest degradation and data were mapped on forest cover and land use maps. Perceptions of villagers were compiled in a pictorial representation to understand changes in forest resource distribution in central Himalaya from 1970 to 2010. Forested areas were subject to degradation and isolation due to loss of connecting forest stands.

Ecological support for rural land-use planning

Journal Articles & Books
Décembre, 2005

How can ecologists be more effective in supporting ecologically informed rural land-use planning and policy? Improved decision making about rural lands requires careful consideration of how ecological information and analyses can inform specific planning and policy needs. We provide a brief overview of rural land-use planning, including recently developed approaches to conservation.

Land use regulates carbon budgets in eastern Germany: From NEE to NBP

Journal Articles & Books
Décembre, 2010
Allemagne

The concentration of carbon dioxide in the atmosphere is influenced by land use and management. Here, the carbon (CO₂-C) budgets of a managed forest (spruce), a grass site and a crop site (crop rotation) have been compared to examine the effects of different management practices on net ecosystem exchange (NEE) and net biome productivity (NBP). This approach enables a more comprehensive carbon budgeting as it takes into account carbon exports and imports for particular land uses.

Factors determining soil nutrient distribution in a small-scaled watershed in the purple soil region of Sichuan Province, China

Journal Articles & Books
Décembre, 2009
Chine

Determining soil nutrient distribution is critical to identify sites which are at risk of N and P loading. Equally important are determining factors that influence such distribution (e.g. land use, land management, topography, etc.). In this research, soil nutrient distribution and its influencing factors were studied in a small-scaled watershed in the purple soil region of Sichuan Province, China. The watershed is 1.3km² with a complex land management system including agriculture and forestry.

Analysing decadal land use/cover dynamics of the Lake Basaka catchment (Main Ethiopian Rift) using LANDSAT imagery and GIS

Journal Articles & Books
Décembre, 2012

Development of accurate classification methods for rapidly changing catchments like that of Lake Basaka is fundamental to better understanding the catchment dynamics, which were not addressed in previous studies. Thus, the aim of this study was to map the decadal land use/cover (LUC) regimes of the Lake Basaka catchment, utilizing time series of LANDSAT images and to analyse the changes that occurred at different time periods. Both unsupervised and supervised image classification systems were utilized in Earth Resources Data Analysis System (ERDAS) Imagine (9.1).

Urban land use types contribute to grassland conservation: The example of Berlin

Journal Articles & Books
Décembre, 2013
Allemagne

Urbanisation is an important driver of biodiversity loss, also contributing to habitat loss and fragmentation of grasslands at the urban-rural interface. While urban green spaces are known to include many grassland habitats, it is uncertain to what extent urban land use types harbour grasslands of special conservation interest and whether patch characteristics and connectivity of these differ from grasslands on agricultural land.
