This dataset was derived from a variety of sources to provide a dataset of the remaining natural habitats of the Indo-Malayan Realm at around the year 1990; change over time can be seen when used alongside the original natural habitats dataset. It was produced alongside the publication "Protected Areas Systems Review of the Indo-Malayan Realm, Mackinnon, J. ed. 1997" in collaboration with The Asian Bureau for Conservation (ABC). This was produced to document the growth and changing character of the protected areas systems of the region over the ten year period 1986-1996. This was in the hope of aiding conservationists and development practioners to conserve Asia's rich biological resources upon which so many depend.

Global congruence of carbon storage and biodiversity in terrestrial ecosystems »

Deforestation is a main driver of climate change and biodiversity loss. An incentive mechanism to reduce emissions from deforestation and forest degradation (REDD) is being negotiated under the United Nations Framework Convention on Climate Change. Here we use the best available global data sets on terrestrial biodiversity and carbon storage to map and investigate potential synergies between carbon and biodiversity-oriented conservation.

Carbon in Drylands: Desertification, Climate Change and Carbon Finance »

This paper reviews the potential for carbon sequestration in dryland ecosystems, which includes forests, but also covers other habitats, such as grasslands, and, importantly, soils. It also considers ways in which carbon storage in drylands affects land degradation issues.

Global Generalised 'Original' Forest: This dataset, compiled from various sources at UNEP-WCMC, shows the original extent of global forest cover before human impact. It is divided into needle-leaf forest (NF), non-forest (NON), temperate, broadleaf and mixed forest (TBMF), tropical dry forest (TDF) and tropical moist forest (TMF). This dataset can be used with the dataset showing current forest cover to identify broad change.
Global Generalised 'Current' Forest: This dataset, compiled from various sources at UNEP-WCMC, shows the current (1998) extent of global forest cover. It is divided into needle-leaf forest (NF), non-forest (NON), temperate, broadleaf and mixed forest (TBMF), tropical dry forest (TDF) and tropical moist forest (TMF). This general dataset of global forest cover was produced from a series of regional datasets containing more detailed information of the forest cover. This dataset can be used with the dataset showing original forest cover to identify broad change.

To provide a global context for a discussion of mountain forests, it is first necessary to define the locations and types of mountain forests, and this in turn requires a definition of mountains or mountain areas. Altitude and slope and the environmental gradients they generate are key components of such a definition, but their combination is problematic. Simple altitude thresholds both exclude older and lower mountain systems and include areas of relatively high elevation that have little topographic relief and few environmental gradients. Using slope as a criterion on its own or in combination with altitude can resolve the latter problem, but not the former. As a first step to evaluating global mountain forest resources and the threats to them, UNEP-WCMC (in collaboration with the Environmental Change Institute and kindly supported by the Swiss Agency for Development and Co-operation - SDC) in 2000 made a first attempt to map the mountain forests of the world.

Carbon Storage in Protected Areas »

This reports looks at the carbon storage function of protected areas as a contribution to the development of strategies for reducing emissions from land use change. In particular, it is relevant to the current discussions surrounding reducing emissions from deforestation and forest degradation (REDD) under the UN Framework Convention on Climate Change (UNFCCC).

Altitude and slope and the environmental gradients they generate are key components of such a definition, but their combination is problematic. Simple altitude thresholds both exclude older and lower mountain systems and include areas of relatively high elevation that have little topographic relief and few environmental gradients. Using slope as a criterion on its own or in combination with altitude can resolve the latter problem, but not the former. The mountains dataset shows the location of mountain land estimated from a digital elevation model using criteria based on elevation alone (the upper three classes: > 2 500 metres) and at lower elevation, on a combination of elevation, slope and local elevation range. This is an update of the Mountain's of the World 2000 and was produced for the UNEP-WCMC publication Mountain Watch, 2002.
The mountains dataset has been overlayed with a global data set on percent tree cover taken from MODIS 1-km resolution percent tree cover data, courtesy of University of Maryland Global Land Cover Facility. Species richness, density and forest height tend to reduce with increasing altitude; the boundary between forest vegetation and more open ground cover at higher elevation 'the treeline' is an ecological marker signifying the transition to more extreme climatic conditions.

Carbon, biodiversity and ecosystem services: Exploring co-benefits. Nigeria: Preliminary Results »

Well-planned and carefully implemented REDD+ actions can have positive outcomes that are additional to emissions reductions. Such ‘cobenefits’ include conservation of biodiversity and maintenance of ecosystem services. Potential cobenefits from REDD+ are highly relevant in Nigeria, where services provided by forests make an important contribution to the livelihoods of local communities (Aruofor 2001).
Spatial analyses relating potential co-benefits to carbon stocks can support planning and decisionmaking on REDD+. Simple mapping tools can be used to help identify areas where high carbon, high biodiversity priority, and ecosystem service values overlap, and show how these relate to pressures and management options. This brochure presents results from some initial spatial analyses for Nigeria.

Carbon and biodiversity: A demonstration atlas »

The 24 page demonstration atlas, launched at the 14th Conference of the Parties to the United Nations Framework Convention on Climate Change, shows that areas high in both carbon and biodiversity do exist and can be identified by relatively simple mapping tools. Prioritising such areas could give the 'double benefit' of reducing emissions from land use change whilst conserving biodiversity. Three regional maps along with six national maps are shown for the tropics, derived from global-scale data.

Letters: Benefits of self-reporting »

This brief note suggests that Laurance and Venter’s proposal to replace developing countries’ role in the process of monitoring forest carbon stocks for the REDD programme may not be in the long-term interests of promoting reduced emissions from forests in developing countries.
