As we knew District Dera Ghazi Khan Punjab Pakistan is one of those districts that are situated in the strip of “Koh e Suleman and Indus River” certainly this district is earthly minded by multiple disasters due to climate stress gradually increasing. This climate stress increase the temperature and weather routine. This climate change leads to threats of of desertification and drought with food insecurity in District Dera Ghazi Khan.
Desertification means land degradation in the dry lands, which are technically known as arid, semi-arid and sub-humid areas. It is a gradual process of soil productivity loss and the thinning out of the vegetative cover that occurs as a result of human activities and climatic variations such as prolonged droughts and floods.
Desertification control is defined as “activity involving the integrated development of land in arid, semi-arid and dry sub-humid zones with the objective of sustainable development, aimed at preventing and/or reducing land degradation, repairing partially degraded land, and at restoring desertified lands.
The desertification parallel causing food insecurity in District Dera Ghazi Khan Punjab Pakistan could be reducing by taken measures as under:
1. Reforestation and tree regeneration.
2. Introduction of xerophytes plants and tree.
3. Efficient use of water — management, saving, reuse of treated water, rainwater harvesting, desalination, or direct use of seawater for salt-loving plants and by introducing drip and sprinkler irrigation systems.
4. Fixating the soil through the use of sand fences, shelter belts, woodlots and windbreaks
5. Enrichment and hyper-fertilizing of soil through planting
6. Farmer Managed Natural Regeneration (FMNR), enabling native sprouting tree growth through selective pruning of shrub shoots.
7. The residue from pruned tress can be used to provide mulching for fields thus increasing soil water retention and reducing evaporation.
