Freshwater Animal Diversity Assessment
The Freshwater Animal Diversity Assessment gives a state of the art assessment of the diversity and distribution of Metazoa in the continental waters of the world. The project deals with all major animal groups plus the macrophytes, and encompasses the complete array of terrestrial aquatic ecosystems. It is the most comprehensive study of species- and genus-level diversity and chorology of the global freshwater fauna to date, and is the first to present comparable data on the different faunal groups concerned. The project draws from the collected expertise of numerous world-renowned taxonomic experts that have bundled efforts to produce this outstanding volume. The result is invaluable to all scientists, managers and conservationists interested in non-marine aquatic animals.
Economics of Land Degradation and Improvement : A Global Assessment for Sustainable Development
This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation.
Aquatic Biodiversity II : The Diversity of Aquatic Ecosystems
The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers
