Our land. Our home. Our future.
This must be our motto today – especially in the struggle against desertification.
The role of environmental changes in migration and population displacement across the world is increasingly clear. Massive numbers of ‘environmental refugees' are now regularly presented as one of the most dramatic possible consequences of climate change and desertification. And this is only set to increase. By 2030, the Secretariat of the United Nations Convention to Combat Desertification warned that 135 million people were at risk of being displaced because of desertification, with 60 million people expected to move from sub-Saharan Africa to Northern Africa and Europe.
These forecasts show that arid and semi-arid regions would be mostly affected by desertification and population movements. Rural populations, relying on pastoral livelihoods, agriculture and natural resources, will be highly exposed due to existing vulnerabilities, including poverty, poor levels of education, lack of investment, remoteness, and isolation.
We must counter these trends and this means acting at two levels.
First, we must manage land correctly, because this is crucial in preventing its desertification and for keeping its productivity. The UNESCO Biosphere Reserve Las Bardenas Reales in Spain shows that informed management of arid lands, based on an alternation between pasture uses, cultivations and fallow periods, allows not only the halt of desertification but also the possibility of inverting the process and restoring previously degraded lands. This is why the UNESCO International Hydrological Programme is so committed to build capacity and provide policy guidance and tools to address drought and desertification related challenges, particularly related to water resources management, through the Global Network on Water and Development Information for Arid Lands (G-WADI).
首先，要正确管理土地，因为这对防治土地荒漠化和保持土地生产力至关重要。西班牙 Las Bardenas Reales教科文组织生物圈保护区的经验显示，以放牧、耕作与休牧、休耕交替的方式对干旱土地进行知情管理，不仅可以防止荒漠化，而且还可能会逆转进程，使退化的土地得到修复。正因如此，教科文 组织国际水文计划通过干旱地区水资源及其发展信息全球网，正努力开展能力建设工作并提供政策指导和工具，以解决特别是与水资源管理相关的干旱和荒漠化问题。
Second, we must bolster the resilience of vulnerable populations by supporting alternative livelihoods to break the vicious circle of desertification and related socioeconomic consequences often leading to migration. In seeking to foster education and capacity building in science, technology and engineering, for both girls and boys in vulnerable countries, UNESCO's International Basic Sciences Programme is working to create new employment opportunities for youth, lessen the reliance on climate dependent income resources, to offer people a future that is resilient at home.
On this day, we must recognise that desertification is a global phenomenon that threatens everyone and we must start to act globally to build a sustainable and stable future for all.
