A Good Assurance of Food Security Requires a Good Understanding of the Plant-Soil-Water-Living Being and Climate Change Interaction

Abstract

The impacts of climate change on agriculture can have repercussions on global food security. Losses in agricultural yield can lead to food shortages and increases in food prices, particularly affecting the most vulnerable populations. Climate change can result in food insecurity due to water resource scarcity, while soil degradation may worsen production problems. A quality harvest depends on optimal climatic conditions. However, climate change, characterized by infrequent or irregular precipitation and high temperatures, leads to a decrease in yield on one hand. On the other hand, these climate changes have an additional negative impact by deteriorating soils and reducing water resources through evaporation, reaching yield limits. Within this chapter, the authors explore the different interactions between plants, soil, water, and climate change. The objective is to design strategies specifically tailored to the changing climatic context, thus enabling the development of an agricultural sector that is both resilient and sustainable.
