The first step would be creating a map database of all the agricultural landscapes, their climate, water and soil resources, biodiversity, … And then, another estimate of the consumption needs of each country. With this information, the UE can estimate what has to be produced, and distribute the different crops that are needed over the map, considering where each crop is going to be adequate without overexploiting the ecosystem. It is no longer sustainable – it never was, to start with – to subsidize monocultures, or help planting rice fields in dry lands, forcing farmers to use extra water from aquifers. Now we intend to solve it with water transfers from one watershed to another – terrible in biodiversity terms, due to invasive species – in order to keep afloat something unsustainable.
Dry-land crops in dry lands, irrigation crops in humid lands. Laws, policies, and programs have to be done from the start following an ecological perspective, that pays attention to sustainability and ecosystem needs. The Earth needs society to be engaged with its preservation that will stop focusing on the economic perspective that overexploits the land. Wetlands, among other ecosystems, are suffering our greed. Their degraded state affects biodiversity, but also us, and we can, and must adapt our lifestyle in order to protect them.
