Protected Area - Protection of Natural Resources

Protection of Natural Resources

Protected areas are designated with the objective of conserving biodiversity and providing an indicator for that conservation's progress, but the extent to which they defend resources and ecosystem dynamics from degradation are slightly more complex. Protected areas will usually encompass several other zones that have been deemed important for particular conservation uses, such as Important Bird Areas (IBA) and Endemic Bird Areas (EBA), Centres of Plant Diversity (CBD), Indigenous and Community Conserved Areas (ICCA), Alliance for Zero Extinction Sites (AZE) and Key Biodiversity Areas (KBA) among others. Likewise, a protected area or an entire network of protected areas may lie within a larger geographic zone that is recognised as a terrestrial or marine ecoregions (see, Global 200), or a crisis ecoregions for example.

Subsequently, the range of natural resources that any one protected area may guard is vast. Many will be allocated primarily for species conservation whether it be flora or fauna or the relationship between them, but protected areas are similarly important for conserving sites of cultural or indigenous importance, and considerable reserves of natural resources, such as;

• Carbon Stocks: Carbon emissions from deforestation account for an estimated 20% of global carbon emissions, so in protecting the worlds carbon stocks greenhouse gas emissions are reduced and longterm land cover change is prevented, which is an effective strategy in the struggle against global warming. Of all global terrestrial carbon stock, 15.2% is contained within protected areas. Protected areas in South America hold 27% of the world's carbon stock, which is the highest percentage of any country in both absolute terms and as a proportion of the total stock.

• Rainforests: 18.8% of the world's forest is covered by protected areas and sixteen of the twenty forest types have 10% or more protected area coverage. Of the 670 ecoregions with forest cover, 54% have 10% or more of their forest cover protected under IUCN Categories I – VI.

• Mountains: Nationally designated protected areas cover 14.3% of the world’s mountain areas, and these mountainous protected areas made up 32.5% of the world’s total terrestrial protected area coverage in 2009. Mountain protected area coverage has increased globally by 21% since 1990 and out of the 198 countries with mountain areas, 43.9% still have less than 10% of their mountain areas protected.

Annual updates on each of these analyses are made in order to make comparisons to the Millenium Development Goals and several other fields of analysis are expected to be introduced in the monitoring of protected areas management effectiveness, such as freshwater and marine or coastal studies which are currently underway, and islands and drylands which are currently in planning.
