Multiple site tower flux and remote sensing comparisons of tropical forest dynamics in Monsoon Asia
The spatial and temporal dynamics of tropical forest functioning are poorly understood, partly attributed to a weak seasonality and high tree species diversity at the landscape scale. Recent neotropical rainforest studies with local tower flux measurements have revealed strong seasonal carbon fluxes that follow the availability of sunlight in intact forests, while in areas of forest disturbance, carbon fluxes more closely tracked seasonal water availability.
Modeling Urban Growth Effects on Surface Runoff with the Integration of Remote Sensing and GIS
A methodology is developed to relate urban growth studies to distributed hydrological modeling using an integrated approach of remote sensing and GIS. This linkage is possible because both studies share land-use and land-cover data. Landsat Thematic Mapper data are utilized to detect urban land-cover changes. GIS analyses are then conducted to examine the changing spatial patterns of urban growth. The integration of remote sensing and GIS is applied to automate the estimation of surface runoff based on the Soil Conservation Service model.
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.
Land selection for cultivation of sugar beet in Slovakia
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
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.
Indigenous Land Use in the Ecuadorian Amazon: A Cross-cultural and Multilevel Analysis
Among the remaining tropical forests of lowland Latin America, many are inhabited by indigenous peoples, and the sustainability of their land uses is a point of heated debate in the conservation community. Numerous small-scale studies have documented changes in indigenous land use in individual communities in the context of expanding frontier settlements and markets, but few studies have included larger populations or multiple ethnic groups.
Land Use Issues: The Last Settler’s Syndrome
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
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.
Integrated approach for understanding spatio-temporal changes in forest resource distribution in the central Himalaya
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
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
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.
