Environmental change and overuse planting material have become major effected on crops health. For example increase temperature air 2 c has high effect on yield and integrate temperature with overuse for N-fertilizer have negative effect not only crops also for environmental.
Heat, drought and salinity stresses are main risks caused by environmental change on agriculture. So, addition of promoting natural planting materials is recommended to increase yield.
Coping with these challenges will require investing more on biodiversity. In other words, when planting a crop, rather than considering one single variety, it will be more productive to plant seed of the same crop from different varieties. This approach will be the approach to avoid the risks of losing everything if the single variety does not survive.

This idea summarizes the work of Italian agronomist Salvatore Ceccarelli who coined the term: "evolutionary breeding" regarding the enhancement of plants/crops adaptations to a changing environment. You can see his work on RG.
