How does poverty contribute to unsustainable land management in dryland regions?

In dryland regions, poverty is a significant driver of desertification, as it often forces populations to rely on unsustainable land-management practices to meet immediate survival needs. When communities lack the capital or resources to invest in sustainable agricultural infrastructure, they may be compelled to overexploit the land, leading to a decline in biological productivity.12

In many arid and semiarid environments, subsistence farmers face challenges such as limited acreage, labor shortages, and a reliance on unpredictable rainfall. To survive, these farmers may engage in practices like shifting agriculture or nomadic pastoralism, which require moving to new sites once the soil or forage is exhausted. While these methods can be sustainable when land is abundant, poverty-driven pressures—such as the need to maximize output from small, degraded plots—can prevent the land from lying fallow long enough to rejuvenate.34

Ultimately, the inability to access modern, sustainable technologies or inputs forces a reliance on natural resources that, when overused, exacerbate the degradation of fragile dryland ecosystems.12
