Global Food Security: Man-Made Threats
To obtain a list of the major man-made threats to global food security.
Global Food Security
- Deforestation is a great contributing factor. Clearing land for large-scale agriculture is a practice that has cleared peat lands, mangroves, and grasslands which eventually degrades the soils.
- Such activities expose these regions to massive shifts in climate cycles which could result in mass migrations.
- Human beings have failed to protect the earth's biodiversity. Within the past 20 years, 20% of the world's vegetated land has become less and less productive.
- Many species that would indirectly affect the growth of crops have reduced which has affected the harvest volumes.
- The species that are under the greatest threat are plants, birds, and fish and fungi.
- It is also important to note that pollinators also face these threats. 17% of vertebrate pollinators face extinction.
- Even though food production has increased globally, the world depends heavily on nine main species: sugar cane, maize, rice, wheat, potatoes, soybeans, oil-palm fruit, sugar beet, and cassava.
Wastage of Water
- Currently, the global fishing fleet is 2.5 times more than the ocean's ecosystem can handle.
- 52% of the global fisheries are currently fully exploited and 24% are either depleted, over exploited, or recovering.
