Micro-level analysis of farmers' adaptation to climate change in Southern Africa

Adaptation to climate change involves changes in agricultural management practices in response to changes in climate conditions. It often involves a combination of various individual responses at the farm-level and assumes that farmers have access to alternative practices and technologies available in the region.

Do trees grow on money? The implications of deforestation research for policies to promote REDD

Dezembro, 2006

This paper provides a brief overview of the current knowledge and data on deforestation rates, research on the causes of deforestation and forest degradation and relevant policy options. It highlights issues of particular relevance to new discussions on reduced emissions from deforestation and forest degradation (REDD) in developing countries at different stages of forest transition.

Future European agricultural landscapes--What can we learn from existing quantitative land use scenario studies

The structure of agricultural production and spatial patterns of agricultural land use in Europe are expected to face major changes over the next decades due to changes in global trade, technology, demography and policies. This paper presents a set of 25 scenarios comprising information on quantitative land use changes in Europe. The scenarios have been selected from studies with different foci, operating on both different spatial scales and different time horizons.

Developing scenarios and visualisations to illustrate potential policy and climatic influences on future agricultural landscapes

The future evolution of our agricultural landscapes and countryside is the subject of considerable debate and policy discussion, alongside which is an increasing emphasis on the inclusion of public consultation and participation within planning and decision making systems. However, communicating different proposed policy options in a manner that facilitates informed decisions from stakeholders can be far from straightforward. This is particularly true with more abstract and uncertain issues such as potential impacts of climate change.

Vulnerability of African mammals to anthropogenic climate change under conservative land transformation assumptions

Recent observations show that human-induced climate change (CC) and land transformation (LT) are threatening wildlife globally. Thus, there is a need to assess the sensitivity of wildlife on large spatial scales and evaluate whether national parks (NPs), a key conservation tools used to protect species, will meet their mandate under future CC and LT conditions. Here, we assess the sensitivity of 277 mammals at African scale to CC at 10[prime] resolution, using static LT assumptions in a 'first-cut' estimate, in the absence of credible future LT trends.

Land-use change and carbon sinks: Econometric estimation of the carbon sequestration supply function

If the United States chooses to implement a greenhouse gas reduction program, it would be necessary to decide whether to include carbon sequestration policies---such as those that promote forestation and discourage deforestation---as part of the domestic portfolio of compliance activities. We investigate the cost of forest-based carbon sequestration by analyzing econometrically micro-data on revealed landowner preferences, modeling six major private land uses in a comprehensive analysis of the contiguous United States.

Definition of British Water Beetle Species Pools (Coleoptera) and their Relationship to Altitude, Temperature, Precipitation and Land Cover Variables

Journal Articles & Books
Dezembro, 2006

Pooled water beetle species lists from 1826 British national grid 10-km squares were analysed using multivariate ordination and classification methods. The relationships of pool groups to the climate, altitude and land cover variables were assessed using constrained and partial ordinations. Ordination of the species pool data indicated a major trend between squares in the north-west of Scotland and those in southern England, illustrating differences in acid and basic water standing water. Secondary variation was from acid standing water to fast-flowing streams and rivers.

Europa

This paper presents a range of future, spatially explicit, land use change scenarios for the EU15, Norway and Switzerland based on an interpretation of the global storylines of the Intergovernmental Panel on Climate Change (IPCC) that are presented in the special report on emissions scenarios (SRES). The methodology is based on a qualitative interpretation of the SRES storylines for the European region, an estimation of the aggregate totals of land use change using various land use change models and the allocation of these aggregate quantities in space using spatially explicit rules.

Scenario development to explore the future of Europe's rural areas

Europa

Changes in rural areas, such as depopulation and land abandonment, but also intensification and loss of biodiversity, usually proceed very slowly yet are often irreversible. A scenario study (called EURURALIS) was carried out by Wageningen University and Research Centre in combination with the Netherlands Environmental Assessment Agency (MNP) to stimulate the strategic discussion among both national policy makers and policy makers at the European Union level on the future of Europe's rural areas and the role of policy instruments.

New weed threats: extent, origins, and proper management.CAB Reviews

Journal Articles & Books
Dezembro, 2006

Weed problems continue to be an obstacle in plant protection and in natural areas, causing high costs of control and asking for adequate prevention measures. New weed problems in any given area (risk area) may arise from three basic sources: by introduction and naturalization of new weedy plant species, by increasing spread of weedy taxa that are already present in the risk area, and by the evolution of new weedy taxa in the risk area.
