5 Content and structure of the new Atlas After draft proposal of Dr. L. Vermes suggested after the WAD meeting in Ispra, JRC, 3-5 Dec Editorial (Aim and method of the updating work Some addresses of special personalities) 1. General introduction 1.1 Preliminaries 1.2 Historical background 1.3 Merits and weaknesses of the previous Atlas 1.4 Needs of updating 2. General thematic considerations 2.1 Recent development in the evaluation and assessment of the relevant processes 2.2 Major achievements of R&D activities worldwide concerning our topic (Overview on what happened during the last years in the different countries and in international projects, like MA, LADA and WOCAT) 2.3 New possibilities in illustration techniques and assessment methods 2.4 Remaining boundaries of implementation 2.5 Connections to other global issues (conventions), like climate change and biodiversity 2.6 Aim of the Atlas and recommended audience 2.7 How to use this Atlas? 3. Section One: global issues (JRC) 3.1 Benchmarks and indicators 3.2 Assessment at global level 3.3 Global theme maps and thematic baselines on desertification and/or land degradation 4.
