Sustainable land and water management combined with reforestation can mitigate the effects of desertification on fragile global ecosystems [1].
These strategies are critical because the loss of fertile land threatens food security and biodiversity, particularly in regions where climate change intersects with poor land use.
Serena Ferrari, an economist and researcher at CIRAD, said that desertification is driven by climate change, but economic and political choices can intensify the pressure. She identified intensive water use, chemical-dependent agriculture, and the pursuit of ever-higher productivity as factors that exacerbate the problem [1].
Mongolia serves as a primary example of this crisis. As a pastoralist, rangeland country, the effects of desertification have become increasingly visible across its landscape [1]. Experts said that restoring vegetation cover can reduce the stress placed on these environments.
Some nations have attempted large-scale interventions to halt the spread of arid conditions. In 1971 [2], Algeria began planting a "green dam" to protect its semi-arid high plateaus [2]. This project consists of a forest belt 1,500 kilometers long and 20 kilometers wide [2].
Technological integration is also entering the field. Sergey Rybakov said that drones equipped with artificial intelligence (AI) will help combat desertification [3]. Such tools can potentially monitor soil health and automate the planting of seeds in remote or degraded areas.
Ferrari said that the goal is to move away from unsustainable economic choices that prioritize short-term yields over long-term ecological stability [1]. By implementing sustainable water management, regions can maintain the moisture levels necessary to support plant life, and prevent soil erosion.
“"Desertification is driven by climate change, but economic and political choices... can intensify pressure on already fragile ecosystems."”
The shift toward sustainable land management represents a move from reactive crisis control to proactive ecosystem restoration. While large-scale projects like Algeria's green dam provide a physical barrier against sand encroachment, the integration of AI and a departure from chemical-heavy agriculture suggest a more data-driven, holistic approach to preserving arable land in the face of rising global temperatures.
