Desertification is a complex phenomenon defined as the extreme degree of land degradation induced by human activities and climatic conditions. Climate change is accelerating and widening these areas. Previews analysis and studies assessed the vulnerability to desertification in Italy at national and regional level through a methodological approach based on integrating climate, soil, vegetation, and socio-economic data (ESA). The studies carried out by ISPRA aim to provide an update of the of land degradation assessment in Italy, based on Trends.Earth methodology and of the three UN-SDGs sub-indicators on Target 15.3.1 (land use/land cover, land productivity and soil organic carbon above and below ground status and trends), together with additional dimensions of land degradation considered crucial for national land characters. Final assessment of the percentage of degraded land is around 36% of national area. This exercise demonstrates the importance to consider a larger number of data and include information on other factors, such as climate, physical, chemical data. This integrated approach to the assessment of land degradation will allow to describe also of the loss of related ecosystem services.

可持续土壤管理的土地退化评估

荒漠化是一种复杂的现象,定义为人类活动和气候条件引起的极端程度的土地退化。气候变化正在加速和扩大这些领域。预览分析和研究通过基于整合气候、土壤、植被和社会经济数据 (ESA) 的方法论,评估了意大利在国家和区域层面对荒漠化的脆弱性。ISPRA 开展的研究旨在根据 Trends.Earth 方法和目标 15.3.1(土地利用/土地覆盖、土地生产力)的三个联合国可持续发展目标子指标提供意大利土地退化评估的更新和地下土壤有机碳状况和趋势),以及被认为对国家土地特征至关重要的土地退化的其他方面。最终评估的退化土地百分比约为全国面积的 36%。该练习表明考虑大量数据并包括其他因素信息的重要性,例如气候、物理、化学数据。这种评估土地退化的综合方法也可以描述相关生态系统服务的损失。
