Climate changes affect the abundance, geographic extent, and floral composition of vegetation, which are reflected in the pollen rain. Sediment cores taken from lakes and peat bogs can be analysed for their pollen content. The fossil pollen records provide information on the temporal changes in climate and palaeo-environments. Although the complexity of the variables influencing vegetation distribution requires a multi-dimensional approach, only a few research projects have used GIS to analyse pollen data.

Land use and land cover changes in the Brazilian Amazon have major implications for regional and global carbon (C) cycling. Cattle pasture represents the largest single use (about 70%) of this once-forested land in most of the region. The main objective of this study was to evaluate the accuracy of the RothC and Century models at estimating soil organic C (SOC) changes under forest-to-pasture conditions in the Brazilian Amazon. We used data from 11 site-specific 'forest to pasture' chronosequences with the Century Ecosystem Model (Century 4.0) and the Rothamsted C Model (RothC 26.3).

This report seeks to present micro evidence on how environmental changes affect poor households. It focuses primarily on environmental resources that are outside the private sphere, particularly commonly held and managed resources such as forests, fisheries, and wildlife. The objectives for this volume are three-fold. It is first interested in using an empirical data-driven approach to examine the dependence of the poor on natural resources. The second objective is to examine the role of the environment in determining health outcomes.

The purpose of this review is to outline the status quo regarding multifunctional and social demands on grasslands. The products and services that grassland ecosystems can provide society are detailed. Existing agro-policies are reviewed as to how they reflect social demands on grasslands. A farm level analysis considers many factors that may influence the fulfilment of social demands. Conclusions are drawn on the future of grassland use under different socioeconomic conditions.

Much is reported about the destruction of natural forests and the consequences for global warming, while on the other hand, exotic plantations in some regions struggle to gain public acceptance. The earth's population is projected to rise to around 9 billion by 2050, with a concomitant increase in demand for forest products. Inevitably, forests in general, and managed forest in particular, will be called on to provide an ever-increasing proportion of local supplies and the international wood trade.

In Europe, grassland is one of the dominant forms of land use. Within 20 years, the area of permanent grasslands and pastures in Western Europe has declined by 12%. Semi-natural grasslands are often hot spots of biodiversity and are threatened both by intensive farming and by the abandonment of farmland in marginal areas. In this review, we show that biodiversity, climate change, C sequestration and farming systems issues are highly interconnected in grassland ecosystems.

Designers, architects and planners must begin to anticipate the far reaching changes we are facing in connection with climate change. What if we take action and actively participate in the transition from fossil-fuel driven society towards a more sustainable society? This Wageningen University paper intends to discuss some of the spatial opportunities and consequences of a sustainable energy transition in relation to climate change and depletion of fossil-fuels.

De landschappen in ons land zijn ‘man made’ en tot enkele decennia geleden nog met een geheel eigen ‘gezicht’. De afgelopen halve eeuw zijn er telkens schoksgewijs grote landschappelijke veranderingen aan de orde geweest door veranderingen in het landgebruik, en de effecten van klimaatverandering komen daar nog bovenop. Dit rapport gaat in op de effecten die optreden door de ‘mediterranisatie’ en zeespiegelrijzing en hoe dat doorwerkt in de identiteit van het landschap. Landschappelijke verandering mondt uit in het verloren gaan van kenmerken, maar er ontstaan ook weer nieuwe.

The main objective of the Country Environmental Analysis (CEA) in Nepal is to identify opportunities for enhancing the overall performance of select environmental management systems through improvements in the effectiveness of institutions, policies, and processes.

The general trend of climatically-driven treeline advance is modified by regional, local and temporal variations. Treelines will not advance in a closed front parallel to the shift of any isotherm to higher elevations and more northern latitudes. The effects of varying topography on site conditions and the after-effects of historical disturbances by natural and anthropogenic factors may override the effects of slightly higher average temperatures. Moreover, the varying treeline-forming species respond in different ways to a changing climate.

Land is very important natural resource to the human being as it provides the basis for more than 95% of human food. On the broader context, land has many other functions, e.g. provision of biological habitats and physical and connective space; regulation of hydrology and climate; storage of minerals, raw materials and historical/pre-historical records; and as a buffer to control waste and pollution. Expanding human requirements and economic activities are placing ever increasing pressures on land resources, creating competition and conflicts and resulting in suboptimal use of land.

Paul Wolfowitz, President of the World Bank, discussed how to meet the rising demand for energy while reducing our carbon footprint. Rich countries need to lead by example, renovating and replacing infrastructure and investing in clean technology. Rich countries also need to lead with direct support to developing nations, both to reduce poverty and reduce carbon emissions. Moving to a low carbon path will require investments, and a long-term equitable global regulatory framework to reduce greenhouse gas emissions.
