Carbon (C) storage and its dynamics in vegetation and soil are important for predicting how terrestrial ecosystem carbon pools may change as climate and land use change in the next future. In this context, the organic fraction of the C stored in the above-ground biomass (CA), below-ground biomass (CB), deadwood mass (CD), litter (CL) and soil (CS) was estimated for different plant land-cover categories: forests (i.e.

To contribute to the aspirations of recent international biodiversity conventions, protected areas (PAs) must be strategically located and not simply established on economically marginal lands as they have in the past. With refined international commitments under the Convention on Biological Diversity to target protected areas in places of “importance to biodiversity,” perhaps they may now be. We analyzed location biases in PAs globally over historic (pre-2004) and recent periods.

Conserving threatened species requires identifying where across their range they are being impacted by threats, yet this remains unresolved across most of Earth. Here, we present a global analysis of cumulative human impacts on threatened species by using a spatial framework that jointly considers the co-occurrence of eight threatening processes and the distribution of 5,457 terrestrial vertebrates. We show that impacts to species are widespread, occurring across 84% of Earth’s surface, and identify hotspots of impacted species richness and coolspots of unimpacted species richness.

Estimating the effectiveness of protected areas in reducing deforestation is useful to support management decisions. This information helps underpin whether to invest in better management of areas already protected or to create new ones. Statistical matching is commonly used to assess this effectiveness, but regional differences in protection effectiveness and the presence of spatial autocorrelation are frequently overlooked. We assessed methods to estimate the effectiveness of protected areas, using Colombia as a case study.

The purpose of the present study, included in the research project SECOSUD Phase II, called “Conservation and equitable use of biological diversity in the SADC region (Southern African Development Community) [1], is to describe the existing baseline situation in term of geological and hydrogeological conditions of the Kruger National Park, providing a starting point for understanding the water resources status quo, potential hydrogeological issues and concerns to assure a sound and correct water resources management in a so sensitive and complex area [2].
