    Description: A policy framework for sustainable resource management (SRM) is required both to guarantee the materials and energy supply of the EU economy and safeguard the natural resource basis in the future. Goals and strategies for sustaining the metabolism of the economy are described. Data are presented on the material throughput and physical growth of the EU's economy, on total material requirements (TMR), its composition, the decoupling from economic growth, and the increased shift to other regions. A first future target Material Flow Balance (t- MFB) of the EU is outlined. Detailed data reveal the "top ten" resource flows. Policy design for SRM should aim at an integrated and balanced approach along the material flow, comprising resource extraction, the product cycle and final waste disposal. Strategies and potential instruments to manage fossil fuels, metals and industrial minerals, construction minerals and excavation are discussed. Possible priorities and examples are given for target setting, focusing on limited expansion of built-up area, reduced use of non-renewables, increased resource productivity, and shift to sustainable cultivation of biomass.

    Description: This report focuses on the contribution of ICT to improvements in resource efficiency and transport intensity at the macro, meso and micro levels. It presents the research on environmental effects of e-business and e-work. The research strand explored the implication of ICT and its applications from the micro- (case study), meso- (different e-business types) and macro-level (macro-economic and policy level). The "macro-analysis-module" aimed at quantifying the potential contribution of e-business and ICT to dematerialisation and resource productivity. The analysis followed a top-down approach complementary to the case study based microanalyses. It compromised the analysis of energy-use and selected material flows (CO(2)) of three EU Member States to determine whether there is any macro-level evidence of dematerialization and increased resource productivity resulting from e-business and ICT. From a micro and meso level perspective, the research object has been the provision of new IT based applications instead of "traditional" products, services and customs (e-commerce and telework). The research quantified the resource- and transport efficiency of e-business in different case studies and identified key factors determining the impact on resource- and transport efficiency.

    Description: Southern African coral communities form a continuum from the more typical, accretive reefs in the tropics of Mozambique to the marginal, southernmost African distribution of this fauna in KwaZulu- Natal. While the latter are limited in size, they are gaining increasing attention as they provide a model for the study of many of the stresses to which these valuable systems are globally being subjected. Soft coral cover, comprising relatively few species, exceeds that of scleractinians over much of the southern reefs, and the coral communities attain a high biodiversity at this latitude on the East African coast. A long-term monitoring programme has revealed small yet significant changes in community structure on the reefs in recent years, concurrent with consistent increases in mean and maximum temperature. Insignificant bleaching was encountered during the 1998 ENSO event, unlike elsewhere in East Africa, but quantifiable bleaching occurred during an extended period of warming in 2000. Outbreaks of crown-of-thorns starfish (COTS) have caused longer-term changes in isolated areas. A study of coral larval dispersal and recruitment has been initiated to establish the capacity of the reefs to recover from the latter form of disturbance. The marginal nature of the reefs is further manifested by corals that generate aseasonal and atypical natural products and have a reproductive pattern that conforms with the pattern found on marginal reefs in western Australia. Calcium deposition on the reefs is also low due to physico-chemical factors that are related to latitude. Published projections on the long-term effects of climate change indicate that more reefs will become marginal as a result of global warming. Current monitoring on the South African reefs is being expanded to investigate the extent to which they will elucidate the future of more typical reefs.
