Umiversity,It examines thepossibi1ities for and restrictions on food production and shows that theproblems of foad security can be ascxibed to factors other than  \nbiotechnical ones.Political and economic restrictions have more effect onthe produetion and distribution of food in the world than do technologicalIimitations,This is demonstrated in this paper,which 111ustrates thebasic principles of Theoretical Production Ecology.  \n# 1.INTRODUCTIQN\n\nFor centuries,food production was the primary occupation of themajority of the population,Untii about a century ago(in the case of theNetherlands,until 1860),more than 50%of the working population in theindustrialized countries was engaged in agriculture and even today a largeproportion of the wor1d's population are farmers or farm Labourers.Thedecrease in the proportion of the population engaged in food productionover the last 100 years has occurred at a particularly fast rate in theindustrialized countries.In the Netherlands,some 5%of the workingpopulation are employed direct1y in the agricultura1 and horticulturalsectar,while in other industrialized countries,this percentage is evenconsiderably Iower.This is because non-soi1-dependent agricu1ture andhorticulture(greenhouses,mushroom cultivation,intensive livestockfarming)are more developed in the Nether1ands than eLsewhere in Europe.  \nThe enormous changes in the number of people employed in agriculturehave been caused by a rise in soi1 and 1abour productivity.This has beenmade possible by the fact that this sectot was able to make use ofproducts deve1oped by industry.Investments in 1and reclamation works,mechanization,improvement of soi1 ferti1土ty and crop protection are onlypossible if fndustry produces the machines,the art土ficia1 fertilizers and  \nThis chapter has been adapted from a pub11caon by De wit(1971)。  \nthe crop protection technologies and agents required.This combination ofinputs from several economic subsectors has led to the increase in soiland labour productivity.There is scope for this to continue in some 99%of the world's agricultural areas and,if these developments are managedproperly,food production for the ever-increasing population can beguaranteed and the burden on the environment and natural habitats reduced,enabling the development of sustainable agricultural systems.  \n# 2.HISTORY OF AGRICULTURE\n\n## 2.1 Agriculture in the middle ages\n\nIn the early middle ages,around 100 families were needed to maintainthe fifteen monks and several servants living at a monastery situatedclose to the French town of Antver.These farming families produced justenough surplus food to feed a number of \"white-collar workers\".They wereclassic farming families,who only worked on the land.They produced some800 kg of grain per hectare each year of which,because of its poorquality and competition with weeds,a relatively large amount of some 200kg were needed as seed for the next year's crops.Of the remaining 600 kg,half went to the animals which worked the land and to beer production.Thequality of the water was bad and the meat people ate was generally sosalty that enormous amounts of beer were consumed.Only 300 kg of grainper hectare remained for food -just enough to provide one person a yearwith a meagre cereal diet.With the low level of mechanization in themiddle ages,cultivating one hectare involved a great deal more labourthan it does today.It took at least 500 hours to cultivate each hectare,so one person working ful1-time could farm no more than 2 to 3 hectares,since almost all the work had to be done in the growing season.At themoment,Northwestern Europe's highly productive agriculture producesaround 7,500 kg of grain per hectare per year.No more than 150 kg of seedand some 15 hours of work go into each hectare.In short,the l","cbCaikwImR5BjPIb","https://ap.wps.com/l/cbCaikwImR5BjPIb","pdf",1570178,22,"English","# 1.
