Desert Green: Groundwater Key to Fighting Desertification
5 Jan
Summary
- Groundwater is crucial for plant growth in drylands.
- Vegetation restoration effectively prevents desertification.
- Semi-shrubs are vital for desert ecosystems with or without groundwater.
A collaborative study by Chinese and German researchers has illuminated the vital link between groundwater balance and plant water-use efficiency in desert ecosystems. This research provides crucial insights into combating desertification through effective ecological restoration strategies.
The findings indicate that replenishing groundwater transforms soil water storage, enhancing actual evapotranspiration and seepage. This process significantly bolsters plant growth, particularly in arid drylands where water scarcity is a major impediment. The study emphasized that groundwater-dependent ecosystems demonstrate superior actual evapotranspiration compared to those lacking this resource.
Vegetation reconstruction, especially with appropriate plant configuration, is identified as a key solution for preventing desertification and ensuring the long-term sustainability of restoration projects. Semi-shrubs, in particular, were found to play a pivotal role, offering a direct basis for recommending plant choices in desert environments.
