Preface Greengenetechnology(GGT),understoodasapartofmodernbiotechnology, has been on a steady, triumphal progression over the last ten years (ISAAA 2007,seethecontributionbyEinseleinthisissue).Thisvolume,jointlyedited byProf.Fiechterandme,dealswithsomeactualscientificandsocio-economic aspects with regard to genetically modified plants (GMP). Worldwide more than 100 million hectares of agronomicalland are covered by GMP. This in- cludes some prominent industrialised Western countries like the USA and Canada,aseriesofthresholdcountrieslikeArgentina,Brazil,IndiaandChina, andanumber ofdeveloping countries. Clearly, someofthesecountrieshave todealwithcropplantproductionandhumannutritioninaverypragmatic waysince,forexample, Indiahastofeedabouta1/5oftheworldpopulation on about 3% of the arable land. In contrast, the situation in Europe appears verydifferent. Foodsupply ismorethansufficient andcomparablyinexpen- sive. This surplus of food is on one hand convenient, since starvation has beenlargelyunknowninEuropeforabout50years,withonlycomparatively fewexceptionsofsociallyperipheralindividuals. Ontheotherhanditmakes thepopulationcarelessaboutthefuturefoodsupply.Evenbeyondmerefood supply,Europegaineditsculturalvaluesfromitsagriculturalsuccessoverthe centuries.Asinglefarmerbecameabletofeedmoreandmorepeoplemaking themfreetoworkoutsideofagricultureasacraftsman,artist,poet,scientist, engineer,mayor,administrativeofficial,priest,philosopher,orsoldier–togive onlyafewexamples.Inthepublicperceptionthisconnectionbetweenagron- omyandculturalwelfareisnotsufficientlyappreciatedinEurope.Switzerland, geographicallyin the centre ofEurope (although not a member of the polit- ical union) has the same cultural tradition, only somewhat shifted towards themoreconservativemoodcommontomountainpopulations.Insummary, amajorityofEuropeans,andtheSwisspopulationinparticular,arereluctant tonewmethodsinagronomy. Switzerlandisprobablytheonlycountryworldwidethathasamoratorium onthecommercialgrowthofgeneticallymodifiedplantsinitsconstitution.In contrast,themoratoriumforGMPintheEuropeanUnionbetween 1999and 2004 was not legally binding. In Switzerland it was thepopulation itself that establishedthismoratoriumintofundamentallawbymeansofareferendum. Moreover,allSwisslegislationaboutgenetechnology,theso-called“Genlex”, X Preface is probably the strongest law in place that attempts to prevent the abuse of genetechnologyworldwide.Thisincludes,forexample,protectingthedignity of organisms. We are not aware of any other country in the world that has extendedthetermdignityoforganismstoplantsatthelevelofmakingitlaw orthathasincludedthisextensioninitsreleaseordinance,whichalsoregulates fieldexperimentswithGMP.Dignityofplantsisparticularlydifficulttodeter- mine,sincemostofthecategoriesknownfromdignityofanimals,likenatural behaviour or sexual propagation, are not applicable to crop plants, which havebeenbredtoexhibitveryunnaturalbehaviour.Potatoes,forexample,are mostlypollensterile,oftenseedsterile,andhavebeenartificiallyselectedfor lossoftheiralkaloidsinthetuber,whichmakesthemaneasyvictimtomany predators or pathogens. This exposure to its enemies would be a clear con- tradictiontoanimal dignity.Howeversince we havelittleimagination about aplant’s“wellbeing”,evenethicalexpertspubliclyconveyasomewhathelpless impressionwiththisissue. Thisparticularlystrongpositionofthegenetechnologylegislation,guided by the public mood against gene technology is remarkable in Switzerland, sincethiscountryowesaconsiderable partofitswealthtothechemicaland pharmaceutical industries, which depend largely on biotechnology in their moderndevelopment.IndustryresearchanddevelopmentsdealingwithGGT has consequently moved out. The research at the famous industry-owned Friedrich Miescher Institute in Basel is no longer engaged in plant research and the large rice genome project of Syngenta in Stein was first moved to EnglandandthentotheUS.Highregulationhurdlesforasmallcountrymake itveryunattractivetoinvestinderegulationforanagronomicareathatistoo small to get back the investment by selling seeds.

Swiss plant scientists are prominentauthorsintop-rankinginternationalresearchjournals.Theprojects rangefromverybasicresearchlikechromatinstructureandfunctiontofields withanapparentapplicationperspectivelikediseaseresistanceincropplants. A small-scale field test should always be made as the last step for proof of concept at the end of such basic research projects with application perspec- tive. Field tests in Switzerland are officially possible in spite of the morato- rium,whichconcernsonlycommercialapplication.Howeverthehurdletoget a permit is very high. There have only ever been three field tests with GMP inSwitzerlandandonlyonesince1992.Ittookanunaffordable4yearstoget
