3 Agriculture is knwn t have first develped in the,,, and the Yellw and Yangzi River Valleys in. Prbably first, useful tree and vine species were identified, prtected, and imprved whilst. Agricultural techniques such as,, the applicatin f were develped sn after the. When agriculture was develped it led t... permanent civilizatins jb specializatin distinct gender rles patriarchal scieties increase in ttal ppulatin This in turn led t the mre cmplex aspects f civilizatin such as the develpment f, and expansin (empires). It als led t technlgical advancements fr farming. 3

Mdern Agriculture What are LDC s and MDC s? Main difference between agriculture in MDC s and LDC s is MDC s practice and in LDC s practice. Subsistence agriculture prduces fd primarily fr. Cmmercial agriculture prduces fd fr. In < % f wrkers are. In the < % f the wrking ppulatin are. MDC s use which. MDC farm sizes are much than in LDC s. 4

5 MDC s likely have a high ( ), high average incmes, and access t gd educatin. LDC s are the ppsite with typically and sectrs f the ecnmy. Characteristics f LDC s is when land area is cultivated, abandned when the sil becmes depleted, and reverts t while the cultivatr mves n. is an agricultural technique that invlves t create fields. This is nt with, because the land des nt, and s farmers have t mve n t virgin frest and repeat the prcess. is als a prblem fr LDC s because, which can lead t mre slash-and-burning. is a large piece f land where usually ne crp is grwn (tday it is primarily ) fr widespread.

Gvernments f MDC s will pay farmers when and t reduce, and dnate r sell at a reduced price t, that preserve r enhance the, t cntrl, plant, and. 5

6 The Green Revlutin The was a series f, ccurring between the, with the gal f increasing. The aims f the revlutin were t be able t with prductin ut pacing, make plants resistant t, make farming and prcess, replant withut having t let land lay, grw virtually any crp anywhere, cultivate the, and fr increasing prfits. Benefits f the Revlutin : crp lsses frm insects can be devastating resulting in and even. : genetically engineered plants t be resistant t ne very pwerful herbicide culd help prevent damage by reducing the herbicides needed. : bilgists are wrking t genetically engineered plants resistance t these. : an frm has been intrduced int sme plants, with this gene, these plants are able t that nrmally wuld kill unmdified plants. : creating plants that can withstand lng perids f drught r high salt cntent in sil. Nutritin: in cuntries where is a prblem because peple rely n a single crp, the crp culd be genetically mdified t cntain mre nutrients. 6

7 Disadvantages Unintended harm t ther rganisms that such as and. Genes frm engineered plants culd be t ther plants such as weeds. Intrducing a gene int a plant may create a new r cause an in susceptible individuals. There is a grwing cncern that intrducing freign genes int fd plants may have an unexpected and negative impact n. Genetically Mdified Crps Genetically mdified tmates came ut in 1994, and were mdified t remain firm and fresh fr a lng time. Glden rice has been mdified t cntain a large amunt f Vitamin A s when yu eat glden rice yu get mre Vitamin A. Sweet crn has been mdified t prduce pisn which kills harmful insects meaning farmers n lnger needs t fight insects with insecticides. Strawberries, pineapples, sweet peppers, and bananas have all been mdified t remain fresh fr lnger. 7
