The production of essential crops such as wheat, maize, rice, and soybean will be substantially reduced. Effective measures for climate change adaptation will be necessary, as well as improvements in crop genetics in order to reduce the impacts of climate change.
Leaders of the universities and research centres in Catalonia met yesterday to assess the situation here in Catalonia resulting from the actions of the Spanish government in recent days. This is the joint statement.
A new study led by Josep Peñuelas and published in Nature Ecology and Evolution reveals that CO2 abundance in the atmosphere no longer has a powerful fertilizing effect on vegetation. The greening that has been observed in recent years is slowing and this will cause CO2 levels in the atmosphere to rise, thus increasing temperatures and leading to increasingly severe changes in climate.
In an article in the journal Science, Josep Peñuelas warns that we must immediately begin studying the changes we are causing in the microbial world, improve water treatment systems, and change crop fertilization practices.
