旱地林业

本节介绍旱地恢复计划。粮农组织已经开发出两种主要产品以支持世界各地的旱地恢复从业者和决策者:1)干旱地区退化森林和景观恢复全球指南—提高抗灾能力,裨益生计改善”; 2)旱地恢复行动平台(DRIP)及其在线工具,该工具允许汇编和分析数据,收集和分享经验教训,并促进全球干旱地区恢复计划工作者之间的联系。

Dryland Restoration Initiative

Forests in drylands play a significant role in conserving biodiversity, harboring unique and endemic species that are particularly adapted to extreme ecological conditions and providing ecosystem good and services that are essential for people’s livelihoods and well-being. If well managed and properly valued, they have the potential to help tackle such global challenges as poverty, climate change, erosion and desertification. By supporting the millions of people who live in the world’s dry areas, they can ultimately contribute to the FAO mandate of achieving food security.

Yet dryland forests are caught in a spiral of deforestation, fragmentation, degradation and desertification, driven by interrelated and complex factors such as adverse land-use policies and subsidies, poor governance and a general lack of understanding of the importance and vulnerability of these ecosystems, coupled with a lack of investment in their sustainable management and restoration. Moreover, along with desertification, climate change-related phenomena are a huge, and growing concern in drylands. The decrease in rainfall and increase in extreme weather conditions predicted by the Intergovernmental Panel on Climate Change will lead to severe water scarcity and are likely to cause a vicious circle of land and forest degradation, leading to unsustainable livelihoods in rural and urban areas.
