Editor's Notes
Following the quotes and statements one finds around in official publications on how much land degradation would be ongoing globally, Using an array of estimates published mainly between 1990, 1996, and around 2005; this indicates clearly a need to have a new, clear and systematic look at the LDD problem at such global scales to link this better with other global changes of concern. COP8 (when 10yr strat was implemented) already indicated the need for a new WAD WAD implements recent scientiic adavancements 1. Global level baseline on the status and extent of LDD ----- delineation of affected areas … including inventorizing all contributive causal aspects (issues) >Results from Previous and Current reporting cycles suggested that: Still a lack of standardized procedures for monitoring and assessment of LDD Lack of info is hampering implementation of UNCCD – info is requisite to implement 10yr strategy Info crucial/critical for a large and divers set of users No agreement on a methodology exists – WAD facilitates and catalyzes this process (which UNCCD needs) 2. >Although known now that LDD results from complex interactions between bio-physical and societal processes, assessments and mitigation policies do not fully ‘Implement’ this WAD promotes the H-E based vision and has the ambition to illustrate integrated assessment procedures 3. >WAD highlights important aspects and gaps for (indictor) reporting and how these could be integrated Illustrates a number of available and crucial datasets that could be used by countries for their reporting Digital WAD strives to prepare Open Data Platform 4. Basis for economic valuation >
