The World Atlas of Biodiversity is the first map-based view of the world's living resources and so addresses the remarkable growth in concern at all levels for living things and the environment. It provides a wealth of facts and figures on the importance of forests, wetlands, marine and coastal environments and other key ecosystems.
Resource Type: BooksThe Conservation Atlas of Tropical Forest series was produced under the Tropical Forest Conservation Programme of IUCN, with much of the research, editing and map preparation done at WCMC. The Atlases provide an overview of the status of tropical forests, with discussions on their history, agricultural colonization policies and deforestation, conservation polices for plants and wildlife, protected areas and a country-by-country analysis of status and trends. Although these Atlases were produced in the early 1990s, they still provide a valuable reference source for forest conservationists and researchers.

Resource Type: BooksAssuming no radical transformation in human behavior, we can expect important changes in biodiversity and ecosystem services by 2050. A considerable number of species extinctions will have taken place. Existing large blocks of tropical forest will be much reduced and fragmented, but temperate forests and some tropical forests will be stable or increasing in area, although the latter will be biotically impoverished. Marine ecosystems will be very different from today's, with few large marine predators, and freshwater biodiversity will be severely reduced almost everywhere. These changes will not, in themselves, threaten the survival of humans as a species.
Resource Type: Journal PapersSustainability requires living within the regenerative capacity of the biosphere. In an attempt to measure the extent to which humanity satisfies this requirement, we use existing data to translate human demand on the environment into the area required for the production of food and other goods, together with the absorption of wastes. Our accounts indicate that human demand may well have exceeded the biosphere's regenerative capacity since the 1980s. According to this preliminary and exploratory assessment, humanity's load corresponded to 70% of the capacity of the global biosphere in 1961, and grew to 120% in 1999.
Resource Type: Journal PapersOur analyses show significant differences between predictions from different models, with predicted changes in range size by 2030 differing in both magnitude and direction (e.g. from 92 loss to 322 gain). We explain differences with reference to two characteristics of the modelling techniques: data input requirements (presence/absence vs. presence-only approaches) and assumptions made by each algorithm when extrapolating beyond the range of data used to build the model. The effects of these factors should be carefully considered when using this modelling approach to predict species ranges. Main conclusions We highlight an important source of uncertainty in assessments of the impacts of climate change on biodiversity and emphasize that model predictions should be interpreted in policy-guiding applications along with a full appreciation of uncertainty.
