moresystematically andglobally. A particular problem area here isthe importing into economically developedcountries of exotic fruit and vegetables.This can have a negative impact on foodsecurity in two ways. Firstly, importing (andespecially air-freighting) fresh producefromoverseas locations can significantly increasethe carbon footprint of food production, contributing to global warming and itsassociated problems。Secondly, if growersin less economically developed countriesswitch to producing fruit and vegetablesfor export, this could displace local staplecrops, resulting in worsening diets forwhat may be an already malnourishedpopulation.

A further solution is to manage cropproduction to boost yields of some cropsin countries with

temperate climates. However, climate change could also causeshifts in seasonal patterns that put crops

out of rhythm with the insects that pollinatethem, or could increase the likelihoodof extreme weather events damaging thedeveloping flowers that are essential forthe crop .There is a strong likelihood thatdiets will increasingly be dependent onanimal sources of protein, but farmers donot necessarily adopt practices that lead tothe fulfilment of potential yield.

Helpingthem become more efficient offers a furthermeans of addressing the food security issue.

An integrated，systemic approach tothe problems of food security has to bedeveloped. This includes encouraging agri-food research, with themost technologicallyadvanced countriesdirecting their attentionand research focustowards dealing with theproblem. In addition, a globalapproach is needed and specialist research initiatives will need to help with integrating the food-security research undertaken by non-specialist institutions.
