3. Status & Trends in Global Land Degradation
In too many places, achievements in production have been associated with management practices that have degraded the land and water

4. DLDD: Some facts & figures?
Sustainable Development
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

8. Climate change will depress agricultural yields in most countries by 2050 given current agricultural practices and crop varieties
Changes in agricultural productivity by due to Climate change
Source: Müller and others 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

9. 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

11. Intervention Options for ZNLD
Type 1 – High degradation trend or highly degraded lands: 25%
Rehabilitate if economically feasible; mitigate where degrading trends are high
Type 2 – Moderate degradation trend in slightly or moderately degraded land: 8%
Introduce measure to mitigate degradation
Type 3 – Stable land, slightly or moderately degraded: 36%
Preventive interventions
Type 4 – Improving lands: 10%
Reinforcement of enabling conditions which foster SLM
