IntroductionGlobal food security now depends on a fewwidely cultivatedspecies,thethreecrops,wheat,maizeandriceprovidingover50percentoftheworld'sdailyrequirementofproteinsandcalories[1]and12speciescontributingabout80percentoftotaldietaryintake.Bycontrast,wildfoodsprovideagreaterdietarydiversitytothosewhorelyonthem.Morethan7000specieshavebeenreported to be used at some stage in human history, in past,basedonethnobotanicalsurveysofwildplants[2].InIndia,600plantspeciesareknowntohavefoodvalue[3].Manyagriculturalcommunities have been reported to rely on wild plants andanimalseventoday.
Ithasbeenreportedthattheagriculturalandforagercommunitiesat36locationsin22countriesofAsiaandAfricauseanaverageof 90-100 wild species [4]. The access and availability of wildfood resources is now declining due to habitat degradation,developmental activities, agricultural expansion, and othersocial and ecological drivers reducingwild food use.However,withincreasingpressureonenhancedagriculturalproductivity,theimportanceofwildfoodusehasbeenreportedtobesettogrow[4].
Wildplantsinparticulararereportedtohavediverseuses[5-7].Wildplantfoodshavebeenanintegralpartofhumandietsinceancienttimesandnearly75,000speciesofplantsbelievedtobeedible[8-11].About200plantspecieshavebeendomesticatedasfoodcropsofwhichonlyabout30%arereportedtocontribute95%oftheworld’splantfoodintake[12,13].However,despitethe reliance of agricultural communities on conventional cropplants,theruralcommunitiesworldoverstillconsumewildplantfoods[13-17],initsstateoffoodinsecurityintheworldreport,estimatedthataroundonebillionpeopleusewildplantsintheirdiet.
Wildvegetablesplayanimportantroleinthedietofinhabitantsofdifferentpartsoftheworld.AfolayanandJimoh[18]reportedthat the nutrients available inwild vegetables of SouthAfrica,Chenopodium album,Sonchus asper,Solanum nigrumandUrtica urensarecomparablewithorhigherthanthoseofcommonlyusedvegetablessuchasspinach,lettuceandcabbage.Intermsofanti-nutritionalprinciples,allthevegetableshadcomparativelylowerconcentrationsofphytate,alkaloidsandsaponins.Misraetal.[19]documented21wildharvestedleafyvegetablesfromsixvillagesof Nanda Devi Biosphere Reserve buffer zone in Uttarakhandstate,India.Irrespectiveofsocialoreconomicstatusinthestudyvillages, the farmer households had enough knowledge aboutavailabilityanduseofthesewildleafyvegetables.Thetraditionalknowledge, however, is eroding fast due to changing socialvaluesandnon-participationofyoungergenerationincollectionandprocessingofsuchwildfoodresources.Inanethnobotanicalinvestigation carried out in Kendrapara district, Odisha, India,Panda[20]reportedthatwithintheedibleplantparts,leavesandfruitscontributedmaximum(about75%),theremaindersbeingedibletubers,flowersandseeds.Theutilizationofwildvegetablesinthedietaryintakeofthehouseholdswasemphasized.
In Uttarakhand hills, rural farming communities still gatherand consume many edible wild plant resources [21]. Rural
communities use these food plants to supplement their diets.Consumptionof theseplants is particularly vitalwhen there isfood shortage besides contributing to livelihood security andhouseholdeconomiesofnativecommunities.Their importanceis exemplified by free and easy accessibility and nutritionalrichnessespeciallyvitaminsandmicronutrients.Therefore,theyplayasignificantroleinthelivelihoodsofruralcommunitiesinUttarakhandhills.
Research onwild harvested foods in traditional agro-ecologiesfrom forestry/agroforestry systems has so far received limitedattention but it is a matter of great concern from variousresearchers now. Inventorying, in situ conservation and theirpromotion and commercialization are some important actionsrequiredforconservationandsustainableutilizationofwildandneglected foodplants.Asmostof thewildplant resourcesareused locally, theirmanyvalues remainundocumentedwithoutbeing reflected in local, national or international markets.Systematic documentation of indigenous knowledge regardingtheidentityanduseofwildharvestedfoodsbyruralcommunitiesis therefore a necessity as a growing disinterest among theyoungergenerationinthecommunityisoftenobserved.
Theproposedstudytitled“IndigenouslandandfoodsystemsinUttarakhand:Acasestudyontraditionalknowledgeanduseofwildfoodsinagriculturalsystems”thereforesoughtto:

A nutrition transition is clearly evident in farming situationsparticularly of river valleys with the emergence of cash cropeconomies and impact of globalization in recent years. Evenin traditional farming areas nutrition transition in evident ina limited way.

ResultsDocumenting wild plant food resources of Uttarakhand hills A complete list of wild plant food resources from differentrepresentative niche sites of three distinct agro-ecologieswas documented. A total of 335 plant species was recordedin different plant families of Angiosperms, Gymnosperms andPteridophytes. A total of 97 families of dicotyledons and 12families ofmonocotyledons, in Angiosperms; three families ofGymnosperms and one family of Pteridophytes (Ferns) wererepresented (Table 2). Rosaceae (25), Polygonaceae (15),Fabaceae (12), Asteraceae (11), Lamiaceae (10), Liliaceae (10),Urticaceae (10), Amaryllidaceae (Alliaceae 8), Amaranthaceae(8),Caesalpinaceae(7),Rutaceae(7),etc.weretheplantfamilieswith greater species representation among angiosperms.Importantplant species indifferent agroecologies and farmingsituationsarelistedinTable 3.

Anumberofimportantdriversofchangeforwildfoodavailabilityanduse havebeen reported [4]. Food insecurity, for instance,is a particular problem among local communities with crop-livestocksmall-scalemixfarmingsituationsfollowedbynomadicpastoralistsandleastinhouseholdsofrivervalleysinUttarakhandhills. Cultural identity and agrobiodiversity are stronglyassociated, culture and ecosystems are known to co-evolve.Thus,abiophysicaldriver(e.g.climatechange)couldhaveknock-oneffectsonaculturalparameter(e.g.localknowledge),andtheeffectof thetwocombinedcould leadtoeitheran increaseordecreaseinwildfooduse[4].
A comparison of farming communities of three distinct agro-ecologiesofUttarakhandhills revealed insufficientevidence topredicttheimpactsthatclimatechangeonbothhumanforagingand the interlinked processes of LEK transmission, culturalcontinuity and land-based subsistence livelihood.

Yet,theimportanceofwildfoodstonutritionalsecuritymeansthat theyarenotnecessarily replacedbymarket-bought foodsproviding the same amount of calories. When more peopledepend solelyonmarket-bought (cultivated foods), consumingwildfoodswillbemarginalized[4].
AsUttarakhandhillshaveastrongfoodculture,traditionalfoodsystems can persist, andwild foods are still prevalent enoughtobeconsideredanimportantpartoflocaldietsparticularlyincrop-livestockmixfarmingsystemsandpastoralistcommunitiesofhigherHimalayanranges.
Thenutritiontransitionisdrivenbyachangingclimateaswellaslarge-scaleculturalchangesandisexpectedtoproducesignificantnegative effects to physical and mental health at communitylevel. Niche habitatswhere children usewild edible fruits andvegetables, level of malnutrition was low and the benefits ofconsuming traditionalwild foodswere clearly evident. Thoughwildfoodshaveplayedacriticalroleseveraltraditionalfarmingarea across the globe including circumpolar communities,public health policy generally operate within amodel of foodsecurity that discounts the traditional food practices of nativecommunities[4,31,32].
Conclusion Wild plant food resources form a significant portion of thedietarydiversityofthefarmerhouseholdsofUttarakhandhills.However,thecontributionofwildharvestedfoodstototalfoodand nutritional security is under-researched. Constant effortsto increase agricultural production and enhance economicdevelopmenthavethreatenedthecontinuedcontributionofwildspeciestofoodandnutritionalsecurity.Further,thesustainableharvesting of wild economic species requires a strong policysupportbyensuringitscontinuedavailabilityfor livelihoodandnutritionalsecurityoflocalcommunities.
UseofwildfoodresourcesispartofcultureandtraditionsofhillcommunitiesofUttarakhandandispartoftheir livinglinkwith
the land. Decline in traditional ways of life is interlinked withdecreasedwild fooduse.Wild foodspecies, therefore,providemorethanjustfoodandincometohillcommunities.Policiesonconservation, food-security andagriculture, therefore,need tobeintegratedtorecognizeandpreservetheimportanceofwildfoods.
Traditional food revitalization projects aimed at increasingtheconsumptionofwild foods, inorder toprovidehealthandcultural benefits to traditional communities otherwise subjectto the nutrition transition is considered a necessity. It is awell-recognized fact now that wild species and intra-speciesbiodiversityhavekeyrolesinglobalnutritionsecurity.Thewildfoods still provide substantialhealthandeconomicbenefits tothose who depend on them globally. The efforts to conservebiodiversityandpreserve traditional foodsystemsand farmingpractices,therefore,needtobecombinedandenhanced.
