Abstract: | Nutrition of the world's population in the 21st century often appears as an unsolved problem. The challenges are bigger than an increase in agricultural production. From a brief review on the history of food production diverse aspects of the development become evident: innovations with their beneficial and non‐beneficial aspects, e.g. the, green revolution' increasing the rice yields on one hand and the number of landless people on the other. Great differences can be found in agricultural productivity: the yields of the presently area under the plough can be increased. Climate change impacts on the framework of agricultural production with losses and gains of arable land. The challenges of global nutrition cannot be met by innovations in plant breeding and cultivation alone. Socioeconomic factors, education, and health become increasingly important. |
