More than 50% of agricultural

 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

Climate change will depress agricultural yields in Umost
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

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
