- 5. substances that are used to control pests. They include herbicides, insecticides, nematicides, fungicides.
- 6. genetically modified organism which has been modified by humans (e.g. through artificial selection or genetic engineering)
- 8. widespread scarcity of food, caused by several possible factors, including war, natural disasters, crop failure, widespread poverty, an economic catastrophe or government policies.
- 9. process of changing from working largely or exclusively by hand or with animals to doing that work with machinery
- 12. food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
- 14. occurs when an organism gets too few or too many nutrients, resulting in health problems
- 15. crop and livestock production, aquaculture, fisheries, and forestry for food and non-food products. Started with the neolithic revolution.
- 16. agriculture an agricultural production system characterised by the considerable use of. It seeks to produce as much as possible by optimising the labour force, the soil or other means of production.
- 18. artificially adding water to plants
- 19. ...farming: agricultural activity that is limited to self-consumption (also known as traditional farming)
- 20. variety and variability of life on Earth (genetic, species and ecosystems)
- 23. purposeful clearing of forested land.
Down
- 1. land degradation of fertile land into arid desert due to a combination of natural processes and human activities
- 2. period of technology transfer initiatives that saw greatly increased crop yields. These changes in agriculture began in developed countries in the early 20th century and spread globally till the late 1980s.
- 3. the condition of not eating enough food to continue to be in good health.
- 4. ...farming: agricultural activity to be resold on the market
- 7. the quantity of product harvested on a given cultivated surface
- 8. input to avoid fungi in agriculture
- 10. ...cultivation: agricultural system in which plots of land are cultivated temporarily, then abandoned while post-disturbance fallow vegetation is allowed to freely grow while the cultivator moves on to another plot
- 11. trade: arrangement designed to help producers in developing countries achieve sustainable and equitable trade relationships
- 13. medical condition, sometimes considered a disease, in which excess body fat has accumulated to such an extent that it can potentially have negative effects on health.
- 17. farming an agricultural production system that uses resources that are naturally present on the site. It is practised generally over large areas, with relatively low yield per hectare. To increase production, farmers increases the area of cultivated land. Mostly found in developing and poor countries or in neglected rural areas of developed countries.
- 21. from outside: fertilizers, pesticides, etc.
- 22. specialised agriculture for ‘exotic’ products sold in the global north such as bananas, coffee and cocoa.
