The continuing loss of biological diversity and its components, genes, species and ecosystems, is an issue of global concern. Research has shown that both the diversity and the identity of the various species have a fundamental influence on the magnitude and stability of the ecological processes that occur at the ecosystem level. There are significant interrelationships between the degradation of ecosystems, the loss of animal and plant species, market globalisation, and poverty. Europe's high per capita consumption and waste production means that its impact on ecosystems is felt well beyond its own borders. Biodiversity loss is inextricably linked to the degradation of the ecosystem services described by the 2005 Millennium Ecosystem Assessment
As the first indicator-based assessment of progress towards the European target of halting biodiversity loss by 2010, this report serves two purposes. First, it takes stock of the state of biodiversity and its loss in Europe based on the most recent data available. Second, it functions as a bridge to a comprehensive assessment of the 2010 target to be done in 2010. As such, the indicators in this report do not only show what is currently known. They also show where information is missing and what more needs to be measured and examined to enable a comprehensive assessment in 2010.
This is the thirteenth report from the Environmental Audit Committee of the 2007-08 session (HCP 743, ISBN 9780215524843). The Committee states, that the Government will fail to meet the 2010 traget to halt biodiversity loss, although the target might have been unrealistic. The Committee does see some progress, with 80% of Sites of Special Scientific Interest (SSIs) in a favourable condition, with a number of rare species having recovered. In general though, biodiversity loss continues in the wider countryside with many species and habitats facing severe declines and local extinctions. The Committee does believe though that with leadership and effective policies, biodiversity loss could in fact be reversed, and states the Government should adopt a new target to halt the loss. Biodiversity policies need to be cross-departmental, and the Government's ecosystem assessment is a way forward, by encouraging such an approach and promoting biodiversity protection at the regional and local scales. The Committee further states that the Government could make a large contribution in preventing biodiversity loss through more support for the UK Overseas Territories.
As the impacts of anthropogenic activities increase in both magnitude and extent, biodiversity is coming under increasing pressure. Scientists and policy makers are frequently hampered by a lack of information on biological systems, particularly information relating to long-term trends. Such information is crucial to developing an understanding as to how biodiversity may respond to global environmental change. Knowledge gaps make it very difficult to develop effective policies and legislation to reduce and reverse biodiversity loss. This book explores the gap between global commitments to biodiversity conservation, and local action to track biodiversity change and implement conservation action. High profile international political commitments to improve biodiversity conservation, such as the targets set by the Convention on Biological Diversity, require innovative and rapid responses from both science and policy. This multi-disciplinary perspective highlights barriers to conservation and offers novel solutions to evaluating trends in biodiversity at multiple scales.
De studie presenteert de verliezen van biodiversiteit in heden, verleden en toekomst. Ze zijn gekwantificeerd en in geld omgerekend door een internationale onderzoeksteam. De studie werd uitgevoerd in opdracht van de dienst Environment van de EU en het team stond onder leiding van dr. Leon Braat van Alterra. Uit de studie blijkt dat de doelstellingen van een significante afname van het jaarlijkse verlies (de Biodiversiteitdoelstelling 2010 van de Convention of Biological Diversity) en het stoppen van de achteruitgang (de EU 2010-doelstelling) zonder extra beleid niet worden gehaald – zelfs niet in 2050.

This report sets the economic and business case for urgent and ambitious action on biodiversity. It presents a preliminary assessment of current biodiversity-related finance flows, and discusses the key data and indicator gaps that need to be addressed to underpin effective monitoring of both the pressures on biodiversity and the actions (i.e. responses) being implemented. The report concludes with ten priority areas where G7 and other countries can prioritise their efforts.
Abstract: The Nordic countries have agreed on a common target to halt the decline in biodiversity by 2010. This report aims at evaluating the 2010-target by presenting indicators that can describe trends in biodiversity in the Nordic countries. Our results comprise the most comprehensive documentation of land use in the Nordic countries to date. The area of important nature types such as mire, grassland and heathland have decreased significantly over the past one to two decades, whereas the area of constructed habitats, including city areas and transport networks, has grown considerably in all of the Nordic countries. Each of these trends in land use will cause biodiversity to decline. Looking into the quality aspect of biodiversity, our results reveal that two-thirds of the quality indicators presented show declines and the remaining one-third show improvements (or steady-state). Overall, our results indicate that biodiversity has declined in the Nordic countries since 1990. In particular, farmland, mire, grassland and heathland habitats show declines in biodiversity, but also the remaining habitats show negative trends. Therefore, based on the findings from this study, we conclude that it is highly unlikely that the target of halting biodiversity loss by 2010 can be achieved by the Nordic countries. Our results should be perceived as a first attempt to make an overall assessment of biodiversity in the Nordic countries. We believe that if further efforts were directed towards scrutinising existing and historic monitoring programmes and data sources, additional indicators could be calculated and hence a better knowledge base would be achieved

"An audacious and concrete proposal…Half-Earth completes the 86-year-old Wilson’s valedictory trilogy on the human animal and our place on the planet." —Jedediah Purdy, New Republic In his most urgent book to date, Pulitzer Prize–winning author and world-renowned biologist Edward O. Wilson states that in order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet. In this "visionary blueprint for saving the planet" (Stephen Greenblatt), Half-Earth argues that the situation facing us is too large to be solved piecemeal and proposes a solution commensurate with the magnitude of the problem: dedicate fully half the surface of the Earth to nature. Identifying actual regions of the planet that can still be reclaimed—such as the California redwood forest, the Amazon River basin, and grasslands of the Serengeti, among others—Wilson puts aside the prevailing pessimism of our times and "speaks with a humane eloquence which calls to us all" (Oliver Sacks).
