Q.The process of desertification does not have climate boundaries. Justify with examples.

Introduction

The United Nations Convention to Combat Desertification (UNCCD) defines desertification as land degradation in arid, semi-arid, and dry sub-humid areas resulting from climatic variations and human activities. It is a global challenge that transcends traditional climatic boundaries.

Body

Drivers of Desertification:

• Climate Change: Shifting rainfall patterns, rising temperatures, and frequent droughts degrade vegetation cover, initiating desertification.

• Loss of Natural Vegetation: Deforestation, overgrazing, and unsustainable land use expose topsoil to severe wind and water erosion.

• Rapid Urbanization: Expanding urban centers deplete local resources, leaving surrounding lands degraded and vulnerable.

Global Evidence of Desertification Transcending Boundaries:

• Global Scale: According to the FAO, desertification affects nearly two-thirds of all countries, impacting over a billion people.

• Africa: Severe drylands cover two-thirds of the continent, with rapid desert expansion in the Sahel and the Horn of Africa.

• Asia: Expanding deserts in China and India, soil erosion in Nepal, and degraded grasslands in Central Asia make Asia the most heavily impacted continent by population.

• Latin America: Despite hosting vast tropical rainforests, nearly a quarter of Latin America and the Caribbean consists of degraded drylands facing desertification.

Conclusion

Desertification is a pressing global crisis. Achieving Land Degradation Neutrality (LDN) by 2030 requires holistic, trans-boundary land management strategies.
