The document describes the WOCAT-LADA-DESIRE methodology which provides standardized tools for assessing land degradation and sustainable land management at local, national, and global scales. The methodology includes questionnaires, modules, and mapping tools to document SLM knowledge, characterize landscapes, assess livelihoods and ecosystem services, and support decision making. The goal is to build a joint knowledge management and decision support system to facilitate sharing experiences with SLM and inform efforts to scale up successful practices.
