| Sumario: | Land developers often see degraded ecosystems such as patchwork forests and roadside wetlands as prime locations for conversion projects (i.e., roads, housing, or solar farms). Although these resources convey a negative image, “worthless” lands supply basic goods and services for impoverished people during times of hardship. This study reimaged degraded ecosystems with respect to their social value using onsite observations and economic models at several locations in northeast Thailand. Food provisioning was the key ecosystem service. For example, small bogs and remnant trees along roadsides are valuable sources of fish, fruits, and vegetables. Dry Dipterocarp forests and wetlands contribute to subsistence living for rural villagers and those near suburban areas, accounting for 5–46% of annual household income. One tree can provide a measurable source of revenue. Individuals could earn up to 100 Thai Baht (∼US $3 per day; about 1/3 of the national daily wage) for harvesting ant eggs or about 300 Thai Baht per day for gathering mushrooms, vegetables, and other non-timber forest products. Re-thinking the value of degraded ecosystems does not require lofty goals for restoring these resources. Initial steps could include agroforestry practices and planting native food trees: wood-based solutions, to gain community support. |
