Windstorm disturbance effects on mountain stream ecosystems and the Plecoptera assemblages

Journal Articles & Books
декабря, 2015

Within the investigated river basins the deforestation ranged from 0-45.5%, dependent on the amount of windstorm damage. Our water temperature readings revealed that the canopy elimination above the streams in the areas damaged by the windstorm caused increase in daily and annual water temperature and also wider daily water temperature range, than those in the undisturbed reference stream, which caused the decline of cold stenotherm species abundance. The stream basins deforestation was collinear with FPOM and UFPOM concentrations, water temperature gradient and nitrate concentrations.

Role of Forest Income in Rural Household Livelihoods: The Case of Village Common Forest Communities in the Chittagong Hill Tracts, Bangladesh

Bangladesh

Forests play an important role in the livelihoods of ethnic communities living in the south-eastern region, the Chittagong Hill Tracts (CHTs), of Bangladesh. Over decades, deforestation and land degradation have markedly affected ethnic peoples’ livelihoods in the CHTs. Although communities once managed extensive forest commons to support their livelihood needs, population explosion triggered fragmentation of common land leading to a gradual decline in livelihood opportunities.

Anticipated climate and land‐cover changes reveal refuge areas for Borneo's orang‐utans

Journal Articles & Books
декабря, 2015

Habitat loss and climate change pose a double jeopardy for many threatened taxa, making the identification of optimal habitat for the future a conservation priority. Using a case study of the endangered Bornean orang‐utan, we identify environmental refuges by integrating bioclimatic models with projected deforestation and oil‐palm agriculture suitability from the 1950s to 2080s. We coupled a maximum entropy algorithm with information on habitat needs to predict suitable habitat for the present day and 1950s.

Coupling of South American Soybean and Cattle Production Frontiers: New Challenges for Conservation Policy and Land Change Science

Journal Articles & Books

South America

Different drivers and places of land use change in South America have often been studied in isolation. Evidence suggests, however, that in many instances, both places and drivers are becoming increasingly interconnected. The growing diversification and internationalization of agricultural commodity chains is creating new linkages across production frontiers and sectors that have important implications for conservation.

Termite diversity and complexity in Vietnamese agroecosystems along a gradient of increasing disturbance

Journal Articles & Books
декабря, 2015
Vietnam

The rapid development of the Vietnamese coffee industry caused widespread deforestation, land degradation, desertification, and soil and water degradation in the late 1990s. However, little is known about the impact of intensification of coffee farming on arthropod diversity in Vietnamese coffee agroecosystems.

International Finance for REDD+ Within the Context of Conservation Financing Instruments

Journal Articles & Books
декабря, 2015

Reducing Emissions from Deforestation and forest Degradation (REDD+) is a conservation finance instrument based on the payments for ecosystem services model, wherein governments, private landowners, concession holders, and/or communities are compensated for undertaking activities which mitigate greenhouse gas emissions from forest use and land use change. This article reviews the numerous sources for REDD+ finance within the context of total global conservation finance.

Application of the local territorial system of ecological stability in projecting of land consolidation

Journal Articles & Books
декабря, 2015

The paper is aimed on verification of application of local territorial system of ecological stability as landscape-ecological limits and regulations in process of projecting of land consolidation on the model cadastral areas in the district of Žilina. We used informations from project documents on land consolidation provided by the General Land Office.

Soil carbon dynamics following land‐use change varied with temperature and precipitation gradients: evidence from stable isotopes

Journal Articles & Books
декабря, 2015
China

Knowledge of soil organic matter (SOM) dynamics following deforestation or reforestation is essential for evaluating carbon (C) budgets and cycle at regional or global scales. Worldwide land‐use changes involving conversion of vegetation with different photosynthetic pathways (e.g. C₃ and C₄) offer a unique opportunity to quantify SOM decomposition rate and its response to climatic conditions using stable isotope techniques.

Analysis of factors influencing farmers' voluntary participation in reforestation programme in Ghana

Ghana

Policy-makers consider participatory reforestation and forest resource management to be the key to reducing the problems of deforestation and forest degradation. In this regard, the government of Ghana introduced a modified taungya system as a mechanism to restore degraded forest reserves under the National Forest Plantation Development Programme to allow landless farmers access to land for temporary crop production and secured tree tenure rights.

Deforestation and fragmentation of natural forests in the upper Changhua watershed, Hainan, China: implications for biodiversity conservation

Journal Articles & Books
декабря, 2015
China

Hainan, the largest tropical island in China, belongs to the Indo-Burma biodiversity hotspot. The Changhua watershed is a center of endemism for plants and birds and the cradle of Hainan’s main rivers. However, this area has experienced recent and ongoing deforestation and habitat fragmentation. To quantify habitat loss and fragmentation of natural forests, as well as the land-cover changes in the Changhua watershed, we analyzed Landsat images obtained in 1988, 1995, and 2005.

Land use characterization and change detection of a small mangrove area in Banacon Island, Bohol, Philippines using a maximum likelihood classification method

Philippines

Geospatial information of small mangrove islands in the Philippines is usually lacking. Such information is vital to monitor mangrove cover change and craft plans for their sustainable management. This study was conducted to provide some land use information about Banacon Island in Bohol province. The island is renowned for its vast mangrove plantations, community-initiated reforestation, and double reef system. To determine the different forest land uses therein, the study employed a maximum likelihood classification method using two Landsat images of different periods.

Modeling relationships between catchment attributes and river water quality in southern catchments of the Caspian Sea

Journal Articles & Books
декабря, 2015

Increasing land utilization through diverse forms of human activities, such as agriculture, forestry, urban growth, and industrial development, has led to negative impacts on the water quality of rivers. To find out how catchment attributes, such as land use, hydrologic soil groups, and lithology, can affect water quality variables (Ca²⁺, Mg²⁺, Na⁺, Cl⁻, HCO₃⁻, pH, TDS, EC, SAR), a spatio-statistical approach was applied to 23 catchments in southern basins of the Caspian Sea.
