Carbon blinkers and policy blindness: The difficulties of ‘Growing Our Woodland in Wales’

Journal Articles & Books
december, 2013

The need for climate change mitigation has led to a recent upsurge in policies aimed to deliver re-afforestation across the globe, but with mixed successes observed depending upon the levels of private land ownership and ability of governments to engage land managers. This paper evaluates a new government-led scheme in Wales, which is intended to increase woodland cover from 14% to 20% by 2030 to offset the greenhouse gas emissions from agriculture.

Fifty years of herpetological research in the Namib Desert and Namibia with an updated and annotated species checklist

Journal Articles & Books
december, 2013
Namibia

Namibia is mostly an arid and semi-arid country with a high number of reptile and fewer amphibian species. We review the herpetological literature dealing with Namibian species over the past fifty years, and provide up-to-date amphibian and reptile accounts using a widely accepted taxonomy and nomenclature. We critically discuss species accounts, draw attention to the historical development of species inventories for the country, and indicate species endemism for Namibia and the Namib Desert.

Land use and land cover change and driving mechanism in the arid inland river basin: a case study of Tarim River, Xinjiang, China

Journal Articles & Books
december, 2013
China

Identifying the primary causes and examining the processes and trends of land use change are crucial for land use planning, utilization of regional resources and environment management. Combining the ecological quantity analysis with GIS technology, based on the land use data and remote sense images, the changes of land use and land cover and the driving force were analyzed in the mainstream of the Tarim River from 1973 to 2005.

Deforestation and landscape structure changes related to socioeconomic dynamics and climate change in Zagros forests

Iran

The Zagros region of western Iran has been affected by the recent changes both in amount and in structure of forest cover. We evaluated the influence of several driving forces on forest cover and structure, including socioeconomic (urban and rural population and rural income) and climatic (mean annual rainfall and mean annual temperature) variables. We acquired all time series Landsat images of a study site from 1972 to 2009. The images were classified to produce a land cover map of each year.

Evaluation of MODIS gross primary productivity and land cover products for the humid tropics using oil palm trees in Peninsular Malaysia and Google Earth imagery

Journal Articles & Books
december, 2013

Conducting quantitative studies on the carbon balance or productivity of oil palm is important in understanding the role of this ecosystem in global climate change. In this study, we evaluated the accuracy of MODIS (Moderate Resolution Imaging Spectroradiometer) annual gross primary productivity (GPP) (the product termed MOD-17) and its upstream products, especially the MODIS land cover product (the product termed MOD-12). We used high-resolution Google Earth images to classify the land cover classes and their percentage cover within each 1 km spatial resolution MODIS pixel.

Boundary shift of potential suitable agricultural area in farming-grazing transitional zone in Northeastern China under background of climate change during 20th century

China

Climate change affected the agricultural expansion and the formation of farming-grazing transitional patterns during historical periods. This study analyzed the possible range of the boundary shift of the potential suitable agriculture area in the farming-grazing transitional zone in the northeastern China during the 20th century.

Estimation of runoff, peak discharge and sediment load at the event scale in a medium-size Mediterranean watershed using the AnnAGNPS model

Journal Articles & Books
december, 2013

Sediment transport in rivers is an indicator of soil eroded from various sediment sources, of which agricultural land can be a significant one, and the intensity of the phenomenon provides a measure of land degradation at a watershed level.

Keeping wetlands wet in the western United States: Adaptations to drought in agriculture-dominated human-natural systems

United States of America

Water is critical to protecting wetlands in arid regions, especially in agriculture-dominated watersheds. This comparative case study analyzes three federal wildlife refuges in the Bear River Basin of the U.S. West where refuge managers secured water supplies by adapting to their local environmental context and their refuge's relationship to agriculture in being either irrigation-dependent, reservoir-adjacent or diked-delta wetlands.

Land cover and impervious surface extraction using parametric and non-parametric algorithms from the open-source software R: an application to sustainable urban planning in Sicily

Italy

Detailed urban land-cover maps are essential information for sustainable planning. Land-cover maps assist planners in designing strategies for the optimisation of urban ecosystem services and climate change adaptation. In this study, the statistical software R was applied to land cover analysis for the Catania metropolitan area in Sicily, Italy. Six land cover classes were extracted from high-resolution orthophotos. Five different classification algorithms were compared. Texture and contextual layers were tested in different combinations as ancillary data.

Responses to climate change and farming policies by rural communities in northern China: A report on field observation and farmers’ perception in dryland north Shaanxi and Ningxia

China

To address land degradation and rural poverty the Chinese government has put in place a series of land conversion programmes in the Loess Plateau area in northern China. In addition to problems arising from unsustainable land use, water resource availability driven in part by climatic forcing is also a threat to livelihoods in this region. To understand climate impacts on farming practice in poor areas of China, field observation and village reconnaissance took place in the summer of 2009 in three selected counties of Shaanxi and Ningxia Province, northern China.

LandCaRe DSS – An interactive decision support system for climate change impact assessment and the analysis of potential agricultural land use adaptation strategies

Journal Articles & Books
december, 2013

Decision support to develop viable climate change adaptation strategies for agriculture and regional land use management encompasses a wide range of options and issues. Up to now, only a few suitable tools and methods have existed for farmers and regional stakeholders that support the process of decision-making in this field. The interactive model-based spatial information and decision support system LandCaRe DSS attempts to close the existing methodical gap.

meat of the global food crisis

China

The global food crisis has been widely described in terms of the volatility of grain and oilseed markets and the associated worsening conditions of food security facing many poor people. Various explanations have been given for this volatility, including increasingly meat-centered diets and rising demand for animal feed, especially in China.
