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.

This dataset was prepared by IUCN as a contribution to the UNESCO MAB Programme.
The main purpose of the work was to devise a satisfactory classification of the world's biotic areas for purposes of conservation. It is the fourth attempt in a series of revisions, updating the previous three works written by Dasmann.
The logic behind the system was that the plant and animal world occurs within
the biosphere of the Earth in the form of an intertwined network of individuals,
populations and interacting systems. To be able to view them in a systematic way, the biologist may use the following approaches:
Taxonomic order, Ecological order, Phylogenetic order (origins and history).
Biogeographic order - grouping the above entities on a geographic basis.
To define geographic units for conservation purposes the following were considered:
(a) the distribution of species and (b) the distribution of ecosystem units. The
result was a system serving both aims, a hierarchical system of geographical areas which would give a framework for conserving species as well as ecologic areas.
These hierarchical Biogeographical entities were named Realms, Biomes and Provinces.
The first subdivision, the Realm, used the phylogenetic subdivisions of the world, unifying those for flora and fauna. It is a continent or sub-continent-sized area
with unifying features of geography and flora/fauna/vegetation. Eight Realms were distinguished. The second division is the Biome. These were not the same as the
major vegetation formations of the world (see UNESCO, 1973), but combine the features of a major vegetation type with climate. There are 14 of these. These
were largely based on the work of Dasmann. The third, most detailed, subdivision was the Province, delimited on a faunal, floral and ecological basis. There are
186 of these.

The purpose of the work, which began in 1976, was to show how the national forests of the United States fit within the global ecoregional scheme. In this system an ecoregion is defined as any large portion of the Earth's surface over which the ecosystems have characteristics in common. There are three levels in this classification system, the Domains, the Divisions and the Provinces.
Ecoregions of the continents are based on macroclimate (i.e., the climate that lies just beyond the local modifying irregularities of landform and vegetation). The theory behind the approach is that macroclimates are among the most significant factors affecting the distribution of life on Earth. As the macroclimate changes, the other components of the ecosystem change in response. Macroclimates influence soil formation and help shape surface topography, as well as affecting the suitability for human habitation.
Four Domains were defined: Polar, Humid temperate, Humid tropical and Dry. The combination of temperature and rainfall to indicate major climatic zones was based on Köppen and Trewartha's work, where dry climates were treated as a separate entity from Tropical humid and Temperate humid. However, the Köppen system defines an addtional "Subtropical" division at this level.
The next level in the Bailey system is the Divisions, and these are also climate - based, for example in the Humid temperate Domain there is Hot continental, Warm continental, Subtropical, Marine, Prairie and Mediterranean, all with Mountain variants (i.e., a total of 12 Divisions in this Domain). There are a total of 30 of these.
The third and last level are the Provinces, which are based on physiognomy of vegetation, modified by climate. For example, the Forest-Meadow of Eastern Oceanic (Monsoon climate). There are a total of 98 of these subdivisions.
The global map has been digitised and converted to a geographic (lat/long) projection by the WCMC, Cambridge, UK. It is also available on CD from NOAAs National Geophysical Data Center in Boulder, Colorado as part of their Global Ecosystem Database Project. http://www.ngdc.noaa.gov/Store/.
Resource Type: Spatial Data / MapsThis 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).
Resource Type: ReportsThis study combines the best available data on carbon stocks and deforestation with protected area data to estimate the area of forest loss within the protected area network of the humid tropical forest biome during 2000-2005.
Resource Type: ReportsAs the importance of mountain spaces is more widely recogised, it seems necessary to establish a coherent definition of these spaces. The UNEP World Conservation Monitoring Centre (UNEP-WCMC) proposed the first global delineation in 2000. However, certain European countries have used national definitions of mountain spaces since the 1950s. Within the framework of social and economic integration policies at the heart of the European Union, an agreed delineation of European mountain spaces has been established, based on the definition proposed by UNEP-WCMC. The process of adaptation of the global definition to the European context is described, as well as the results for 29 European countries.
Resource Type: Journal PapersAlthough Asian bamboo species constitute a non-timber forest product of major cultural and economic importance, no detailed regional assessment of their distribution patterns has previously been made. To assess the potential of the existing bamboo species distribution data for production of regional mapping tools for planning the conservation of forest-based biodiversity, data on bamboo distribution and forest cover were combined. Over 1000 bamboo species from 60 genera of woody bamboos were incorporated, allowing the mapping of individual species or groups of species and genera, along with potential species richness and biodiversity hotspots. Over 6.3 million km2 of Asian forest potentially contains bamboo, with highest densities indicated from northeastern India through Burma to southern China, and through Sumatra to Borneo. The highest figures for potential species richness (144 spp per square km) were recorded in forests of south China, including Hainan Island. Despite substantial inadequacies and inconsistencies in knowledge of the taxonomy and distribution of bamboo species, this approach may provide a valuable tool for planning in situ conservation of forest biodiversity.
Resource Type: Journal PapersWell-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.
Resource Type: ReportsThe 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.
Resource Type: ReportsSpatial analyses relating to co-benefits can provide key information to support planning and decision-making on REDD+ at national and sub-national scales. To do so, they should be based on data developed at an appropriate scale and should address those benefits and challenges deemed most important by key stakeholders and practitioners.
This report presents results from an initial effort to produce such analyses for Cambodia. It includes new data on the distribution of terrestrial carbon stocks in Cambodia and analyses of its relation to areas of importance for biodiversity, Protected Areas and other land management units, and pressures (such as forest cover loss). It is expected that the study will be developed further in collaboration with other institutes and stakeholders.
