1.Introduction
Unsatainable development goals
➢ loss of biodiversity from deforestation
➢ drought from hydrological cycle change
➢ water pollution
➢ decreasing of productivity in drylands

1/1.Introduction
Target 15.3:
Indicator
✓ dland: degraded land that is degraded over
✓ Σland[a]: total land area
✓ combat desertification,
✓ restore degraded land
✓ strive to achieve a land degradation-neutral world
LDN = dland/Σland[a]

Reflection [???]
❖ The demand for land and land
degradation differ between
countries, region and continent.
Priority [UNEP]: Countries should monitor and
control the level of their global land use by
interpreting it, first in the local context.
Invitation: All UNCCD country Parties should formulate national targets to achieve LDN
Support: UNCCD bodies and creation of Global Mechanism
Target: (1) Land Degradation Neutrality
(2) Human welfare
Soil degradation
Very degraded soil
Degraded soil
Stable soil
Without vegetation

UEM/FC/DCB/017
➢ Evaluate land use, land use change and forestry in 25,000 parcels randomly
placed across the country in the past 15 years through Collect Earth.
➢ Provide the resulting data to SADC institutions as a baseline to define
LDN targets.
