Planet at risk - two research

Le attività umane stanno ridisegnando il Pianeta in modo così radicale da minacciare la sopravvivenza delle generazioni future. L’amara sentenza arriva da una delle ricerche più ampie mai compiute sugli ecosistemi mondiali: il Millennium Ecosystem Assessment (MA), un progetto quadriennale che ha coinvolto 1300 scienziati di 95 Paesi diversi. La loro conclusione è dunque che il 60 per cento dei sistemi ecologici alla base della vita sulla Terra sono sempre più degradati o utilizzati in modo insostenibile.

A questa spiacevola notizia – riportata ieri e oggi un po’ su tutta la stampa mondiale – vanno a sommarsi le ultime rilevazioni sul clima provenienti dalle Hawai. Qui, uno dei più autorevoli laboratori di ricerca – l’americanissimo Climate Monitoring Diagnostics Laboratory , parte del National Oceanic and Atmospheric Administration (Noaa) – ha registrato una nuova concentrazione record di anidride carbonica nell’aria: 378 parti per milione. Il problema - fanno notare i ricercatori del laboratorio – è che l’aumento dei livelli di CO2 è andato aumentando ogni singolo anno a partire dal 1958.

cataclysms, the map of tragedies announced

More than half the world's population is at risk of some natural disaster. A report produced by researchers from several organizations and institutions - from Columbia University at the Norwegian Geotechnical Institute and the World Bank - draws the map of tragedies announced, a world map marked by the "hotspots", the hot spots that are exposed to nature's most violent events: earthquakes , volcanic eruptions, cyclones, droughts and floods as well.

According to the report - titled Natural Disaster Hotspots: A Global Risk Analysis - are 3.4 billion people living in critical areas, ie where the "fury of the elements" could strike with significant results. Among the countries most in danger, Taiwan stands out, a candidate to win the sad scepter of the area with highest percentage of population (73 percent) at risk of two or three different cataclysms. But even in Bangladesh, Nepal, Dominican Republic, Burundi, Haiti, Malawi, El Salvador and Honduras, 90 percent of population living in areas where incumbent upon one or two natural tragedies.

More generally - but the report does not record that the obvious - are the poorest nations in the developing world to have more difficulty in absorbing the impact and the devastating effects of environmental catastrophes, eventually bogged down in a vicious circle of poverty and vulnerability. "With the cycle of natural disasters that repeats itself every few years - said Maxx Dilley, a researcher at the Earth Institute and co-author of the study - in developing countries are in a vicious cycle of destruction and reconstruction, without the ability to go forward and achieve sustainable development. We recommend that the international community manage disaster risk as an integral part of a development plan and not just as a humanitarian emergency. "

The overflow of GM crops in Latin America

in Latin America is now in place for some time a flood of genetically modified crops and fields. From Argentina - now set to become a Republic of Roundup Ready soybeans - to Brazil's Lula with its ambiguities and the creeping contamination incurred by landowners and agribusiness, to Paraguay - officially GMO-free, in fact undergone a massive penetration of GM seeds - and Mexico, the birthplace of corn threatened by the infiltration of North American giant. Spooky, even for the economic dependence and environmental damage it causes, but who vehemently oppose the farmers' organizations and movements sociali.
