Maria José Roxo: "Misuse of natural resources can cause desertification in Portugal"
Maria José Roxo: "Misuse of natural resources can cause desertification in Portugal" Drought, low precipitation and global warming are all problems threatening Mediterranean regions, but other causes, such as intensive agricultural use, might affect desertification.
Between 33% and 41% of world land risks desertification
Between 33% and 41% of world land risks desertification If it’s true that humanity is “living off its ecological credit card and can only do so by liquidating the planet’s natural resources”, as Mathis Wackernagel, director of Global Footprint Network, puts it, then this credit is ostensibly drying out.
Desert of Europe
Desert of Europe Faced with the desertification that threatens Mediterranean Europe, researchers with Desertlink, a European Commission funded project, are trying to curb risk zones by studying certain exacerbating factors.
Preventing Diseases
Preventing Diseases These last years, insect or rodent borne human diseases have been reappearing in Europe. These diseases have serious health, ecological and political consequences. The reasons behind these outbreaks are only partially known.
Vanishing Lakes
Vanishing Lakes Freshwater ecosystems, already under stress from land-use change and pollution, now face additional pressures from climate change, directly and through interaction with other drivers.
