Climate Change Concern to Cattle Feed in Bangladesh

Journal Articles & Books
Décembre, 2011
Bangladesh

This research focuses the climate change concerns for livestock feeding management in Bangladesh as it causes strange behavior and variation of cattle diets and feed shortages in the last two decades. It is obvious from the recent literature that Bangladesh is one of the most climate change vulnerable country of the world to climate change. It causes cattle feed shortages, modification in major production of yields, alteration in a variety composition of rangeland and edifying variety of cattle feed setback.

Water erosion-induced CO₂ emissions from tilled and no-tilled soils and sediments

The acceleration of soil erosion by water in most regions of the world in response to the anthropogenic modification of landscapes is a serious threat to natural ecosystem functionalities because of the loss of invaluable constituents such as soil particles and organic carbon (OC). While soil OC erosion is likely to be a major component of the global C cycle, water erosion-induced CO₂ emissions remain uncertain. In this study, our main objective was to compare the release of CO₂ from eroded topsoils and from the sediments exported by diffuse erosion during an entire rainy season.

Determining the effects of habitat management and climate on the population trends of a declining steppe bird

Journal Articles & Books
Décembre, 2009
Europe

The Little Bustard Tetrax tetrax is one of the most threatened steppe bird species in Europe, due mainly to agricultural intensification. Despite the relative importance of the Iberian population (approximately 50% of the global population) little is known about its dynamics and trends, especially in core distribution areas. This study evaluates the influences of meteorological factors and land management on the oscillations and medium-term trends of two Little Bustard populations in Central Spain.

Rapid deforestation threatens mid‐elevational endemic birds but climate change is most important at higher elevations

Indonésie

AIM: Deforestation and climate change are two of the most serious threats to tropical birds. Here, we combine fine‐scale climatic and dynamic land cover models to forecast species vulnerability in rain forest habitats. LOCATION: Sulawesi, Indonesia. METHODS: We sampled bird communities on four mountains across three seasons in Lore Lindu National Park, Sulawesi, Indonesia (a globally important hotspot of avian endemism), to characterize relationships between elevation and abundance. Deforestation from 2000 to 2010 was quantified, and predictors of deforestation were identified.

Spatial Assessment of Land Degradation Risk for the Okavango River Catchment, Southern Africa

Journal Articles & Books
Décembre, 2016
Afrique australe
Afrique

The Okavango catchment in southern Africa is subject to environmental as well as socio‐economic transformation processes such as population growth and climate change. The degradation of soil and vegetation by deforestation and overgrazing is one of the downsides of this development, reducing the capacity of the land to provide ecosystem functions and services. In this study, climate simulations are brought together with secondary socioeconomic, pedologic and remote‐sensing data in a GIS‐based assessment of the factors commonly associated with land degradation risk.

Wildfire risk adaptation: propensity of forestland owners to purchase wildfire insurance in the southern United States

Journal Articles & Books
Décembre, 2014
États-Unis d'Amérique

The economic and ecological damages caused by wildfires are alarming. Because such damages are expected to increase with changes in wildfire regimes, this calls for more effective wildfire mitigation and adaptation strategies. Wildfire adaptation options for forestland owners include purchasing wildfire insurance, which provides compensation to those insured if a wildfire damages their properties.

Small island developing states: coastal systems, global change and sustainability

Journal Articles & Books
Décembre, 2013

The intent of this paper is to place the concepts of exposure, vulnerability, resilience and risk in the context of the consequences of global change for the sustainable development of small island developing states (SIDS). Many such states face a number of global climate change risks, such as an increase in the proportion of more intense storms, along with other global change threats that include energy security and costs.

Reducing Emissions from Deforestation and Forest Degradation (REDD) in Apuí, Southern Amazonas: Challenges and Caveats Related to Land Tenure and Governance in the Brazilian Amazon

Journal Articles & Books
Décembre, 2012

Climate change mitigation mechanisms related to reducing emissions from deforestation and forest degradation (REDD) may provide significant opportunities for re-arranging political networks and overcome forest governance problems, of which land tenure is the main constraint for REDD and reforestation projects in the Amazon. We present a case study of a pilot REDD project associated with reforestation and payment for environmental services in Apuí, southern Amazonas.

Vulnerability, forest-related sectors and climate change adaptation: The case of Cameroon

Journal Articles & Books
Décembre, 2012
Cameroun

In Cameroon and elsewhere in the Congo Basin, the majority of rural households and a large proportion of urban households depend on plant and animal products from the forests to meet their nutritional, energy, cultural and medicinal needs. This paper explores the likely impacts of climate-induced changes on the provisioning of forest ecosystem goods and services and its effect on the economic and social well-being of the society, including the national economy and the livelihoods of forest-dependent people.

Climate-change impact assessment using GIS-based hydrological modelling

Journal Articles & Books
Décembre, 2011

A GIS-based Soil and Water Assessment Tool (SWAT) model is used to assess the impacts of climate change on the hydrological regime of the Cauvery river basin. First, the impact of changes in land-management practices on water availability under present conditions is modelled. Then, the same analysis is carried out under the future climatic scenarios. Finally, annual and monthly precipitation variability is compared under present, as well as future, climate-change scenarios.

Quantitative mapping of global land degradation using Earth observations

Journal Articles & Books
Décembre, 2011

Land degradation is a global issue on par with climate change and loss of biodiversity, but its extent and severity are only roughly known and there is little detail on the immediate processes – let alone the drivers. Earth-observation methods enable monitoring of land degradation in a consistent, physical way and on a global scale by making use of vegetation productivity and/or loss as proxies. Most recent studies indicate a general greening trend, but improved data sets and analysis also show a combination of greening and browning trends.

Booming during a bust: Asynchronous population responses of arid zone lizards to climatic variables

Journal Articles & Books
Décembre, 2012

The productivity of arid environments and the reproductive success of vertebrates in these systems, are typically thought to be primarily influenced by rainfall patterns. Data from our 15 year study at an Australian arid zone site reveals asynchronous demographic responses to rainfall and other climatic variables among different lizard species.
