城市化是地中海盆地土地覆被变化的重要驱动力，可能会影响生态系统服务的供需。最显着的土地覆盖变化发生在城市周边地区，但很少有人知道这些变化如何影响ES供应。对于8个欧洲城市和4个北非城市，我们分别量化了北方非洲城市16年（1990-2006年）和欧洲城市22年（1990-2012年）的城郊土地覆盖变化。使用专家为基础的方法，我们得出定量估计的动态供应27 ES。欧洲和北非地中海城市的土地覆被变化的性质略有不同，但总体而言，城市地区的土地覆被增加，农业用地减少。在过去的20-30年里，地中海城市周边地区供应环境服务的能力普遍下降。对于9个ES，所有4个北非城市和8个欧洲城市中的3个城市的潜在供应实际上增加了。在所有城市中，生态系统木材、木材燃料以及宗教和精神体验都有所增加。鉴于地中海盆地城市人口的预期增长以及目前对城市地区生态系统短缺的了解，城市周边地区生态系统供应能力的总体下降对地中海地区的人类福祉构成了风险，并对地中海盆地的可持续发展目标构成了严重挑战。
Urbanization is an important driver of changes in land cover in the Mediterranean Basin and it is likely to impact the supply and demand of ecosystem services (ES). The most significant land cover changes occur in the peri-urban zone, but little is known about how these changes affect the ES supply. For eight European and four North African cities, we have quantified changes in peri-urban land cover, for periods of sixteen years (1990–2006) in the Northern African, and twenty-two years (1990–2012) in the European cities, respectively. Using an expert-based method, we derived quantitative estimates of the dynamics in the supply of twenty-seven ES. The nature of land cover changes slightly differed between European and North African Mediterranean cities, but overall it increased in urban areas and decreased in agricultural land. The capacity of the peri-urban areas of Mediterranean cities to supply ES generally reduced over the last 20–30 years. For nine ES the potential supply actually increased for all four North African cities and three out of the eight European cities. Across all cities, the ES timber, wood fuel and religious and spiritual experience increased.Given the expected increase of urban population in the Mediterranean Basin and the current knowledge of ES deficits in urban areas, the overall decrease in ES supply capacity of peri-urban areas is a risk for human well-being in the Mediterranean and poses a serious challenge for the Sustainable Development Goals in the Mediterranean basin.
