- development of this field has helped us to improve life expectancy and quality, but has caused environmental detriment
challenges of acgriulture
- population: it is increasing, so more food is necessary
- importation: more countries rely on imports for foods they are unable to produce, which threatens food supply
- pesticides: increase has damaged the ecosystem
- resources: farming is requiring more land and technology
- global warming: climate change has affected crops
sustainability
ability to produce enough foods for the population
organic
system of farming and food production that aims for sustainability
polyculture
cultures in which there are more than one species or there is crop rotation
agroforestry
culture that grows with the necessities of the natural conditions of the ecosystems surrounding it
crop rotation
periods of cultivation and periods of non culture
permaculture
utilizing the land environment and resources in a non wasteful way
