Producing more food with less land is a serious issue. Indeed the world agricultural area, which amounts to about 46% of earth surface, is actually decreasing whereas global food demand is projected to increase up to 70% in 2050. Therefore there is a need for a better optimisation of agricultural land. Agronomists Memmah et al. review 38 case studies that optimise agricultural landscape in 16 countries using using metaheuristics algorithms.
