Title: Food systems, natural resources, environmental invisibles, land and climate change: Opportunities and challenges in Latin America.

Latin America and the large countries of the region are facing one of the greatest crossroads, both for themselves and for humanity. The enormous availability of land, water and its geographical space under a temperate maritime climate that does not restrict annual production at almost any time, opens up a scenario of new opportunities as well as enormous risks.  Land for agriculture and food systems not only competes with the demand for land for such purposes, but also for new spaces for energy production and the expansion of towns, cities, ports and other infrastructure.  And even with the interference of large international financial capital.  On the other hand, important global research is currently seeking to review and understand the links between water, energy, climate change, health and food systems. Strikingly, "land" as an element, base and anchor for production has not been directly included in such studies.  For Latin America, a region that appears to be the great supplier of this vital element, it seems to be once again the great supplier of land to meet world demand, particularly that of the developed world and India (China and India).

For this reason, this research will focus on what is happening with land use change in the region, its relations with the other resources involved (water, energy, biodiversity) and especially its relations with the different food systems at different scales, from the local to the regional level. On the other hand, these relationships should incorporate new concepts, beyond (economic) externalities, such as environmental intangibles and invisibles, which begin to place value not only on the ecosystem services recovered by sustainable agriculture, but also on the integral value that agriculture provides to society as a whole. Finally, the research contrasts the effects of geopolitical decisions driven by both Europe and China, the former with its farm-to-fork project and investments, and the latter with a growing demand for food products for a population that is changing its consumption patterns and demands. And which, in the latter case, is quite distant from the concern for safeguarding environmental and social variables in the countries of origin of the resources and products it demands. The processes involved have a different impact on regional resources, affect small and medium farmers differently, have an impact on towns and cities, pollute soil and water and promote the loss of genetic resources (biodiversity), and generate other unprecedented investment processes in the region that, in a medium-term scenario, merit review in terms of identifying costs and opportunities for one or the other.
