Food waste contributes to the hunger crisis, in which 690 million people in the world are undernourished [32] and households are the reason behind a significant fraction of food waste. [33] A food chain waste study of Melbourne demonstrated that 40% of waste occurs post-consumer. This adds to the wastage of energy, emissions, and cost of ...

[citation needed]
Mechanical/physical controls include picking pests off plants, or using netting or other material to exclude pests such as birds from grapes or rodents from structures. Cultural controls include keeping an area free of conducive conditions by removing waste or diseased plants, flooding, sanding, and the use of disease-resistant crop varieties. [19]
This can increase water-holding and water use (up to 85% for sand), improve soil permeability, reduce the need for irrigation, reduce compaction, soil erosion, and leaching, and improve plant growth. Desertification and lack of water threaten agriculture in many arid and semi-arid regions of the world; these may be mitigated with hydrogels.
