In too many places, achievements in production have been associated with management practices that have degraded the land and water Status & Trends in Global Land Degradation Source: SOLAW 2011 - FAO
DLDD: Some facts & figures ? SustainableDevelopment • More than 50% of agricultural moderately to severely degraded • LD directly affects 1,5 billion people globally • 75 billion tons of fertile soil disappear/year • 12 million ha/Year lost due to drought and desertification • Six million km2 of drylands bear a legacy of desertification • Biodiversity: 27,000 species lost each year due to LD • 70 to 80 % of expansion of cropland lead to deforestation Food Forest Energy Water DLDD Land/Soil Climate Change Biodiversity loss

Climate change will depress agricultural yields in most countries by 2050 given current agricultural practices and crop varieties Changes in agricultural productivity by 2050 due to Climate change Source: Müller and others 2009. in WDR 2010, Page 145 Note: The figure shows the projected percentage change in yields of 11 major crops (wheat, rice, maize, millet, field pea, sugar beet, sweet potato, soybean, groundnut, sunflower, and rapeseed) from 2046 to 2055, compared with 1996–2005. The values are the mean of three emission scenarios across five global climate models, assuming no CO2 fertilization (see note 54). Large negative yield impacts are projected in many areas that are highly dependent on agriculture
DLDD & Climate Change • The % of Earth’s land area stricken by serious drought has more than doubled from the 1970s to the early 2000s • Climate change will depress agricultural yields by up to 15-50% in most countries by 2050, given current agricultural practices and crop varieties • Agriculture worldwide accounts for around 15% of global greenhouse gas emissions. The related deforestation contributes about 11% • “Improved management of the world’s land (including terrestrial carbon) represents one third of the overall global abatement potential in 2030 (and a half in 2020)1. It represents 7Gt CO2e of mitigation in developing countries in 2020, roughly 40% of the 17Gt CO2e of mitigation required globally” No Carbon neutrality without Land degradation neutrality

Poverty eradication • Improving livelihood through pro-poor policies on Sustainable Land & Water Management • Food Security • Preserving the resource base for food security – Land productivity/Soil fertility improvement at the core of all long term strategies • Drought & Water stress • Improving water availability & quality through sustainable land & water management • Climate change • Land is a win-win context for adaptation, mitigation & resilience building • Biodiversity • Biodiversity conservation through improvement of land ecosystems’ conditions LD Neutrality • Avoided Deforestation • Sust. Land Management & Restoration of degraded Lands as an alternative to Deforestation • Bio Energies • Opportunities for Bio energies through biomass production • Avoiding Forced Migrations • Changing the DAM paradigm • “Degrade-Abandon-Migrate”
