MADRID, Jun 17 2019 (IPS) – Yet another under-reported human-made disaster: the relentless desertification of Planet Earth that may make uninhabitable some regions like the Middle East, endanger food security, aggravate climate crisis, and force more and more millions of people to flee.

But before listing the main causes and consequences of this mounting threat, you should know that, according to the UN, desertification does not refer to the expansion of deserts, but rather the degradation of land in arid, semi-arid and dry sub-humid areas, primarily as a result of human activities and climatic variations.

Now, alerting against such a disaster, specialised world bodies, like the UN, have just reported on the occasion of the 17 June 2019 World Day to Combat Desertification and Drought, that as much as 24 billion tons of fertile land are lost… every single year.

Moreover, degradation in land quality is responsible for a reduction in the national domestic product of up to eight per cent… also every single year.

Among other consequences, desertification, land degradation, and drought will increase forced migrations, and worsen the growing climate crisis.

The World Day, which raises awareness of international efforts to combat desertification, was established 25 years ago, along with the UN Convention to Combat Desertification (UNCCD), the sole legally binding international agreement linking environment and development to sustainable land management, the UN explains.

Three key issues

Running under the slogan “Let’s Grow the Future Together”, the 2019 World Day focuses on the following three key issues as reported by the UNCCD in relation to land: drought, human security and climate.

  • Land and Drought— By 2025, 1.8 billion people will experience absolute water scarcity, and two thirds of the world will be living under water-stressed conditions – when demand outstrips supply during certain periods.
    A complex and slowly encroaching natural hazard with significant and pervasive socio-economic and environmental impacts that to cause more deaths and displace more people than any other natural disaster;
  • Land and Human Security— By 2045 some 135 million people may be displaced as a result of desertification.
    Achieving land degradation neutrality -by rehabilitating already degraded land, scaling up sustainable land management and accelerating restoration initiatives- is a pathway to greater resilience and security for all,
  • Land and Climate Change— Restoring the soils of degraded ecosystems has the potential to store up to 3 billion tons of carbon annually.
    The land use sector represents almost 25 per cent of total global emissions. Its rehabilitation and sustainable management is critical to combating climate change.
