Land Use Issues: The Last Settler’s Syndrome

Journal Articles & Books
Abril, 2010

In the last settler’s syndrome, each new settler wants the area to remain as it was on their arrival. Newcomers’ preferences often differ from long-term residents, and conflicts arise. To explore land use issues among various groups, a survey of opinions on mountain views was developed and administered to Watauga County residents in western North Carolina. Watauga County provides an interesting case study, because it is a growing area with an influx of newcomers along with long-time residents.

Remote sensing and GIS for land use/cover mapping and integrated land management: case from the middle Ganga plain

Journal Articles & Books
Dezembro, 2012
Índia

In India, land resources have reached a critical stage due to the rapidly growing population. This challenge requires an integrated approach toward harnessing land resources, while taking into account the vulnerable environmental conditions. Remote sensing and Geographical Information System (GIS) based technologies may be applied to an area in order to generate a sustainable development plan that is optimally suited to the terrain and to the productive potential of the local resources. The present study area is a part of the middle Ganga plain, known as Son-Karamnasa interfluve, in India.

Water quality, potential conflicts and solutions—an upstream–downstream analysis of the transnational Zarafshan River (Tajikistan, Uzbekistan)

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.

Ecological support for rural land-use planning

Journal Articles & Books
Dezembro, 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
Dezembro, 2010
Alemanha

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
Dezembro, 2009
China

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.

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

Journal Articles & Books
Dezembro, 2012
Austrália

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

Nova Zelândia

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
Dezembro, 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.

Landslide Susceptibility Analysis of Shiv-Khola Watershed, Darjiling: A Remote Sensing & GIS Based Analytical Hierarchy Process (AHP)

Journal Articles & Books
Dezembro, 2012

In the present study, Remote Sensing Technique and GIS tools were used to prepare landslide susceptibility map of Shiv-khola watershed, one of the landslide prone part of Darjiling Himalaya, based on 9 landslide inducing parameters like lithology, slope gradient, slope aspect, slope curvature, drainage density, upslope contributing area, land use and land cover, road contributing area and settlement density applying Analytical Hierarchy Approach (AHA). In this approach, quantification of the factors was executed on priority basis by pair-wise comparison of the factors.
