Worldwide, land degradation, severe droughts and advancing desertification are set to force populations to flee their homes and migrate. In the specific case of the Middle East and North of Africa (MENA), such an obliged choice implies the additional risk to turn peoples into easy prey to extremist, terrorist groups.
This quick conclusion does not come out of the blue–the MENA region, which is home to around 400 million people, is one of the world’s most impacted areas by drought and fast advancing desertification.
The situation is such that several scientific researches have been handling the scary scenario that the MENA region may become inhabitable in very few decades from now, even as soon as 2040.
On this, study-based reports are bold clear. See for instance: New Evidence Confirms Risk That Mideast May Become Uninhabitable. And Will the Middle East Become ‘Uninhabitable’?
The international community is set to mark this year’s World Day to Combat Desertification (WDCD) on June 17, under the theme: “Our Land. Our Home. Our Future.” The Day will precisely examine the important link between land degradation and migration.
The WDCD is observed every year to promote public awareness of international efforts to combat desertification.
What Desertification Is All About?
Desertification is the degradation of land in arid, semi-arid and dry sub-humid areas. It is caused primarily by human activities and climatic variations, according to the United Nations.
“Desertification does not refer to the expansion of existing deserts. It occurs because dryland ecosystems, which cover over one third of the world‘s land area, are extremely vulnerable to over-exploitation and inappropriate land use. Poverty, political instability, deforestation, overgrazing and bad irrigation practices can all undermine the productivity of the land.”
Over 250 million people are directly affected by desertification, and about one billion people in over one hundred countries are at risk, the world body reports. “These people include many of the world‘s poorest, most marginalized and politically weak citizens.”
The World Day to Combat Desertification is a unique moment to remind everyone that land degradation neutrality (LDN) is achievable through problem solving, strong community involvement and co-operation at all levels,” according to the United Nations Convention to Combat Desertification (UNCCD).
“Environmental degradation, political instability, food insecurity and poverty are causes of migration and development challenges.”
In fact, the Bonn-based UNCCD secretariat timely reminds that in just 15 years, the number of international migrants worldwide has risen from 173 million in 2000 to 244 million in 2015.
Drought, the Big Unknown
Drought, a complex and slowly encroaching natural hazard with significant and pervasive socio-economic and environmental impacts, is known to cause more deaths and displace more people than any other natural disaster, says the UN Convention secretariat.
By 2025, 1.8 billion people will experience absolute water scarcity, and two thirds of the world will be living under water-stressed conditions.
Meanwhile, UNCCD reports that the demand for water is expected to increase by 50 per cent by the year 2050. As populations increase, especially in dryland areas, more and more people are becoming dependent on fresh water supplies in land that are becoming degraded. Water scarcity is one of the greatest challenges of the twenty-first century.
“Drought and water scarcity are considered to be the most far-reaching of all natural disasters, causing short and long-term economic and ecological losses as well as significant secondary and tertiary impacts.”
Ten Times Less Available Fresh Water
Per capita availability of fresh water in the region is now 10 times less than the world average, the United Nations has recently warned. Moreover, higher temperatures may shorten growing seasons in the region by 18 days and reduce agricultural yields a further 27 per cent to 55 per cent less by the end of this century.
Add to this that the region’s fresh water resources are among the lowest in the world, and are expected to fall over 50 per cent by 2050, according to the United Nations leading agency in the field of food and agriculture.
Moreover, 90 per cent of the total land in the region lies within arid, semi/arid and dry sub/humid areas, while 45 per cent of the total agricultural area is exposed to salinity, soil nutrient depletion and wind water erosion, the Food and Agriculture Organization of the United Nations (FAO) adds.
On this, UNCCD says that to mitigate these impacts, drought preparedness that responds to human needs, while preserving environmental quality and ecosystems, requires involvement of all stakeholders including water users and water providers to achieve solutions for drought.
“Action on mitigating the effects of drought should be implemented considering comprehensive drought early warning and monitoring systems, vulnerability and risk assessment, upstream-downstream water uses, the link between water and land use; livelihood diversification strategies for drought affected people, etc. For example, addressing land degradation upstream improves access to water on site and downstream.”
The health of land is critical in the search for sustainable solutions to water resource provision and management, the UN Convention secretariat informs. “It is essential for countries to be proactive (rather than reactive); be coordinated at regional level (in addition to the country level actions); holistic and multi-sectoral (rather than silos) and to treat drought as a ‘constant risk’ (rather than a ‘crisis’).”
The global observance of #2017WDCD will be on 15 June in Ouagadougou, Burkina Faso. The Day will be hosted by le Ministère de l’Environnement, de l’Economie Verte et du Changement Climatique.
The UN Convention to Combat Desertification
Established in 1994, UNCCD is the sole legally binding international agreement linking environment and development to sustainable land management. It addresses specifically the arid, semi-arid and dry sub-humid areas, known as the drylands, where some of the most vulnerable ecosystems and peoples can be found.
Its 195 parties work together to improve the living conditions for people in drylands, to maintain and restore land and soil productivity, and to mitigate the effects of drought.
The UNCCD is particularly committed to a bottom-up approach, encouraging the participation of local people in combating desertification and land degradation. Its secretariat facilitates cooperation between developed and developing countries, particularly around knowledge and technology transfer for sustainable land management.
As the dynamics of land, climate and biodiversity are intimately connected, the UNCCD collaborates closely with the other two Rio Conventions; the Convention on Biological Diversity (CBD) and the United Nations Framework Convention on Climate Change (UNFCCC), to meet these complex challenges with an integrated approach and the best possible use of natural resources.
