Thegrowthofaverage calorie supplies percapitagivesanideaofthe nutritional trends, butdoesnotindicate thenumberofundernourished people, whichdepends crucially onthedistribution ofincomeandfoodsupplies. Basedon calorie intakelevelsbelowwhichanindividual's ability tocarryoutminimum necessary activity isseriously impaired, FAOhasestimated thatasof1974-1976 therewere436million undernourished peoplein90developing countries. If present trendscontinue, theirnumberwillreach590million bytheyear2000,or evenmoreiffoodimports arenotgreatly increased. However, ifthetargets of theStrategy forthegrowthinagriculture andfoodproduction areachieved and appropriate national fooddistribution policies areimplemented, thenumberof undernourished peoplewouldfalltoabout260million. 38.Lackofsafedrinking waterandadequate sanitation aremajorcausesofthe deathofmillions ofchildren everyyearinthedeveloping countriesl nearlyhalf thepopulation ofthedeveloping countries suffers fromhealthproblems thatcanbe tracedtounsafewaterandinadequate sanitation.
