The Latin America Regional Nitrogen Centre: Concepts and Recent Activities

The activities related to the International Nitrogen Initiative (INI) Latin America Regional Centre started in the early 2000s, in association with the international actions within the nitrogen (N) field. The office in Latin America was proposed in the context of broad global and local environmental changes and the agricultural need for nutrient addition, looking into processes that would horizontally permeate between these two important elements for human survival and for the Earths system. However, the lack of information on the nitrogen cycle in Latin America is a serious impediment to evaluate properly how human activity is altering nitrogen pools and turnover at regional and global scales. Empirical measurements of N deposition and other N cycle processes are extremely scarce in Latin America, and data feeding to global and regional circulation models lack spatial distribution information in this region.
