C-LLAMA 1.0 (Country-level Land Availability Model for Agriculture) is a statistical-empirical model of the global food and agriculture system. Based on the FALAFEL (Flux Assessment of Linked Agricultural Food production, Energy potentials & Land-use change) model, C-LLAMA aims to address the need for an open and transparent approach to modelling the sensitivity of future agricultural land-use to drivers such as diet, crop yields and food-system efficiency. C-LLAMA uses publicly available FAOSTAT data to make linear projections of diet, food system and agricultural efficiencies, and land-use at a national level, aiming to capture aspects of food systems in both developing and developed nations.
