Rehabilitation of Mediterranean anthropogenic soils using symbiotic wild legume shrubs: Plant establishment and impact on the soil bacterial community structure

Journal Articles & Books
Diciembre, 2010
Italia
Europa

Susceptibility to desertification in southern Europe is increasing and rehabilitation of desertification-threatened Mediterranean soils is a challenge due to the inhospitality of the environment. In particular, recovery of anthropogenic soils (mainly human-derived artefacts from housing construction and other inert materials or topsoil of terminal phase municipal landfills) cannot rely on spontaneous processes and low-cost/low-impact strategies are needed to prevent desertification.

Changing land use/cover patterns and implications for sustainable environmental management in the Irangi Hills, central Tanzania

Journal Articles & Books
Diciembre, 2010
Tanzania

This article examines the changes in land-use/cover types in the Irangi Hills, central Tanzania during the last 45 years and how such changes have influenced environmental and agricultural sustainability in the area. The spatial and temporal changes of land-use/cover were analysed through aerial photographs interpretation. Local perceptions and experiences of changes were addressed through household interviews and field observations.

An analysis of the determinants of flood damages

Conference Papers & Reports
Diciembre, 2010

In this paper we analyze mortality caused by 2,194 large flood events between 1985 and 2008 in 108 countries. Unlike previous studies that looked at natural-disaster mortality, we find that year-to-year changes in income and institutional determinants of vulnerability do not affect flood mortality directly. Income and institutions influence mortality only indirectly, through their impact on the intensity and frequency of floods. Population exposure affects the number of deaths both directly and indirectly.

The present state of the landscapes and territories in the Sahel is the result of interactions between climatic, economic, social and political factors which have been taking place for more than four decades.

Integration of albedo effects caused by land use change into the climate balance: Should we still account in greenhouse gas units

Journal Articles & Books
Diciembre, 2010
Europa

Due to impacts of albedo on climate change, benefits of afforestation/reforestation regimes are under debate. In this paper we investigate how to incorporate albedo changes in a carbon accounting tool to show the net effect of land use change on the climate. Using a study area in southern Europe, albedo and carbon sequestration modelling results are linked to determine the combined radiative forcing balance.

Placing land degradation and biological diversity decline in a unified framework: Methodological and conceptual issues in the case of the north Mediterranean region

Journal Articles & Books
Diciembre, 2010

The development of synergies between efforts to mitigate land degradation and biological diversity decline can enhance effectiveness, speed up implementation and avoid potential conflicts. Due to the variable nature of these processes and to the variable characteristics of the areas where they occur, there is no general rule linking land degradation and biological diversity decline. Thus, a geographically limited approach focusing on drivers of change may provide a more appropriate base upon which synergies can be built. This exercise is undertaken for the case of northern Mediterranean.

National parks and environmental justice: Comparing access rights and ideological legacies in three countries

National parks are often places where people have previously lived and worked-they have been formed by a combination of natural and human processes that embody an identifiable history of cultural and political values. Conservation of protected areas is primarily about how we perceive such landscapes, how we place differential values on different landscape components, and who gets to decide on these values. Thus, conservation has been and still is very much about issues of power and environmental justice.

10-Daily soil erosion modelling over sub-Saharan Africa

Soil erosion is considered to be one of the greatest environmental problems of sub-Saharan Africa. This paper investigates the advantages and disadvantages of modelling soil erosion at the continental scale and suggests an operational methodology for mapping and quantifying 10-daily water runoff and soil erosion over this scale using remote sensing data in a geographical information system framework.

Changes in Butterfly Abundance in Response to Global Warming and Reforestation

República de Corea

In the Republic of Korea, most denuded forest lands have been restored since the 1960s. In addition, the annual mean temperature in the Republic of Korea has increased approximately equal to 1.0°C during the last century, which is higher than the global mean increase of 0.74°C. Such rapid environmental changes may have resulted in changes in the local butterfly fauna. For example, the number of butterflies inhabiting forests may have increased because of reforestation, whereas the number of butterflies inhabiting grasslands may have declined.

CLIMATE CHANGE IMPACTS ON US AGRICULTURE

Conference Papers & Reports
Diciembre, 2010

There is general consensus in the scientific literature that human-induced climate change has taken place and will continue to do so over the next century. The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change concludes with “very high confidence” that anthropogenic activities such as fossil fuel burning and deforestation have affected the global climate.

Climate change‐linked range expansion of Nathusius' pipistrelle bat, Pipistrellus nathusii (Keyserling & Blasius, 1839)

Aim To examine the effect of climate change on the occurrence and distribution of Pipistrellus nathusii (Nathusius' pipistrelle) in the United Kingdom (UK). Location We modelled habitat and climatic associations of P. nathusii in the UK and applied this model to the species' historical range in continental Europe. Methods A binomial logistic regression model was constructed relating the occurrence of P. nathusii to climate and habitat characteristics using historical species occurrence records (1940-2006) and CORINE land cover data.
