Need for re-evaluation of water, forest and agriculture management strategies in Catalan strategy for climate change adaptation24 de April 2018Albert Naya i Díaz
The final conclusions of the LIFE MEDACC project, conducted by the Catalan Office for Climate Change (OCCC) of the Ministry of Territory and Sustainability, CREAF, IPE-CSIC and IRTA, draw attention to the need to adapt forest, agriculture and water management strategies to the new arid conditions expected as a result of climate change. Since 1973, the water flow at the headwaters of the Muga and Ter rivers has dropped by almost half, and the volume of the middle and lower sections of the Segre has decreased by as much as 60%.
Jaume Terradas explains how an error in channeling the water of the Colorado River in California created a large artificial lake that, now, is endangered by the great water demand from the crop fields and nearby cities.
Afforestation is a type of land use change project primarily designated for wood production, soil and water conservation, increasing carbon storage and mitigating climate change. This study shows that afforestation changes, moreover, soil pH, that is a key soil variable.
According to a study Josep Peñuelas has published in Nature Ecology & Evolution, the size of herbivorous megafauna was crucial to their survival in a cold, dry, largely barren environment. The study's data were obtained by incorporating the hugely significant effect of herbivores into innovative mathematical models capable of simulating landscape evolution.
