ارائه آمار و ارقامی راجع به تخریب سرزمین توسط کنوانسیون مقابله با بیابان زایی

UNCCD Executive Secretary Monique Barbut writes in her introduction, "The  numbers tell a story. From it, we can determine what we should do now in order  to make land degradation neutrality a reality for us and for future  generations."

 Among the facts and figures in the publication are the following: humans  obtain more than 99.7% of their food (calories) from land; the soil's nutrient  cycling provides the largest contribution (51%) of the total value (US$33  trillion) of all ecosystem services provided each year; 25% of the world's land  area is either highly degraded or undergoing high rates of degradation; and land  use change and degradation is responsible for about 20% of carbon emissions  globally.

 

The extensively referenced collection of data concludes with the note that  "Achieving land degradation neutrality, i.e. preventing land degradation and  rehabilitating already degraded land, by scaling up sustainable land management  and accelerating restoration initiatives is a pathway to greater resilience and  security for all." [Publication: The Land in Numbers: Livelihoods at a Tipping Point]
