With our climate changes, we have to adapt our ways to a new environment – in most cases warmer and possibly wetter and drier. Projections on the climate in the future provide some guidance for us, but how can we create models for how the human society reacts? This map presents a rough idea of changes in agricultural output from increased temperatures, precipitation differences and also from carbon fertilization for plants. Projecting climate is one thing, but agriculture adds multiple more dimensions of complexity – extreme events, crop rotations, crop selection, breeds, irrigation, erosion, soils and much more.
