摘要

In a world challenged by increasing population, limited natural resources, land fragmentation, urban encroachment, extreme abiotic stresses, incidence of new pests and diseases, and ecosystem destruction, horticulture must find the way and engage thenecessary tools to secure food production, tackle malnutrition and to make the planet a better place to live. Different toolboxes belonging to basic and applied sciences such as biology, ecology, agronomy, and engineering should be identified, optimized,and integrated into a highly efficient and adaptive horticultural machine, coupled and uncoupled from natural rhythms and from local to global scales. In any natural sustainable ecosystem, the population of any species is controlled by food availability. In the case of humans, food availability seems to be controlled by the growing population, leading us to Malthusian alarmism. Since uneven coefficients drive food production and growing human population, predictions estimate that an increase in 20 people will require a 70 increase in food production, a situation that is expected by 2050. This challenge is derived in part from human nature itself but becomes more and more challenging as population trends escape from the control of food availability,which itself is continuously facing limits imposed by resource scarcity and environmental constraints. In a population approaching 8 billion people, about 10 (more than 800 million) worldwide are chronically hungry, while 25 (2 billion) are suffering from micronutrient deficiencies (FAO, 2019). Therefore, feeding and nourishing 10 billion people in an unstable and degraded environment is an uppermost challenge of modern agriculture for the 21st century (Lynch, 2019).
