Changes on ecological footprint

T15 (3): Desertification and degraded land

correction

➢ Evaluate land use, land use change and forestry in 25,000 plots randomly placed

across the country between 2001 to 2016.

➢ Provide the resulting data to SADC institutions as a baseline to define LDN

targets.

5. CONCLUSION

➢ In Mozambique land use changes vary according to the characteristics of each

province (e.g.: demography).

➢ In the 2001-2016 period 6.2% (3.07 million hectares) of the initial forest has been

converted, mainly to agriculture.

➢ About 2.1 million hectares of the remaining forest area may be lost in coming years

due to the occurrence of factors such as shifting agriculture, logging, coal

production.

Collect earth is powerful tool that can be used to evaluate land use and land use

changes in future.
