Bracken is often perceived as a widespread and increasing land management problem. The pollen record of a wide range of sites in Great Britain suggests that the current abundance of bracken is less than or, at worst, equivalent to maximum historical levels. Recently gathered data also suggest that bracken cover is declining. Results of risk assessments of land use change, and experimental and modelling investigations into the effects of climate change are synthesized.

The Belgian climate policy is formulated at the federal level, requiring cooperation between regional and federal administrations. Around a fifth of the total area of Belgium is covered by forests. Around 80/ of the productive forests are in the Walloon region. Reported values for land use change and forestry categories give a potential of 2,057 kt eq. CO2 per year. Given the existing regional forest inventories (RFI): RFI1 for 1984 and RFI2 for 1999, an estimate has been made to consolidate reported data.

This paper explores deforestation and asset accumulation among small scale farmers in tropical forests. In a two-state variable control model, forest clearing is an investment in land holdings and the productivity of forest clearing is a function of non-land assets like chainsaws.

An agricultural watershed, situated on an island of the Aegean archipelago, was studied in order to gain insight into the structure and the design of a typical terrestrial ecosystem of the Mediterranean region. Fieldwork was focused on the comparative study of seasonal patterns of inorganic nutrients, organic nitrogen, and erosion over the most abundant vegetation types of the area, such as olive groves, maquis, and wetlands. Nutrient losses via the pathway of erosion were provided by the determination of nutrient concentrations in runoff sediments.
