  • 1. Climate Change Impact andMitigation/Adaptation Strategies in Nanda Devi Biosphere Reserve(NDBR), Central Himalaya, India DR. R.K. MAIKHURI G B PANT INSTITUTE OF HIMALAYAN ENVIRONMENT AND DEVELOPMENT, GARHWAL UNIT, SRINAGAR GARHWAL, UTTARAKHAND-246174 ,India
  • 2. Biological, cultural and religious significance of NDBR  The NDBR is covered in Himalayan highlands biogeographic province (2A) of India and represents a platform to promote biodiversity conservation in diverse ecosystems and vegetation types (temperate, sub alpine and alpine) The area harbours very rare and endangered floral and faunal elements.  The reserve covers a large number of glaciers feeding the tributaries of the Holy river Ganges. Rich in ethnic diversity (Indo-mongoloid i.e.Tolcha, Marchha, Nitwal, Johari, Darmi and Indo-Aryan) and cultural heritage. The entire landscape of NDBR referred to as very sacred (land of Gods and Goddess)- Dev Bhumi.
  • 3. Map of NDBR
  • 4. Area under core zone and buffer zone in NDBR1. Core zone 624.62 sq.km. Part of NDNP 87.50 sq.km. Whole of VFNP Sub-total 712.10 sq.km (C2)2. Buffer zone 1612.12 sq.km. Old NDBR (total area) 1886.78 sq.km. VF and adjoining 1786.78 sq.km Kakbhushandi zone 1600.01 sq.km Malari-Laptal zone 149.66 sq.km. Sunderdhunga-Pindari zone Sub total 5148.57 sq.km. (BF) Total 5860.69 sq.km.

  • 6. Climate Change Impact (A) Agriculture in Buffer Zone andAdjoining Areas( I ) Negative impact: Diseases, insects/pests etc. Decline in area undercultivation of various traditional crops at three points of time. Hordeum himalayense 60 50 40 Area (ha) 30 20 10 0 1970-75 1980-85 1990-95
  • 7. Greater sensitivity of Hordeum himalayens to increasing temperature causes reduction in cultivated area and productivity The effect of temperature on photosynthetic characteristic of two species of Hordeum(H. himalayense grown in high altitude between 2200-3000 masl) and H. vulgare grown at low altitude (300-1500 masl) were compared. H . himalayense is more sensitive to photosynthesis then the H. vulgare At 300c, photosynthesis in H. himalayense was about 25% less then that of H. vulgare (Joshi & Palni, 2005).
  • 8. 2-Amaranthus spp. vulnerable to climate change –disease called Hymenia rickervalis (between 1000 –1800 masl), high temperature and humidity during1 – 2 week of September which provide favorableconditions to insect whereas no occurrence ofdisease between 2200 – 2800 masl (revealed byfarmers) (Maikhuri et.al.2009,2010).

  • 10.  Cow pea and Vigna spp: Important summer mountain grain legumes facing a problem of fruit setting – due to shift in peak rainfall. Phaseolus spp.: soil borne insect (Coleoptera) damage the crop in early stage of seed germination – increase in moisture/humidity/milder winters (between 500 – 1500 masl) is favorable climatic conditions for the life cycle of the insects. Apple cultivation: Like Kullu valey in H.P., the yield of apple has declined in the villages due to change in snowfall, the chilling hours for apple trees are reduced, affecting the time of its bud-break.(II) Positive impact:1. Opportunities for cash crops like tomato, cabbage, chilly, peas, beans and horticultural crops like prunus, apricot etc.2. Medicinal and aromatic plants cultivation
  • 11. B. Transhumance Pastoralism Decline of livestock population due to various reasons (i.e. conservation policies, socio-economic changes, decline in carrying capacity and water resources in the alpine pastures). 14000 S he e p 12000 G oa t No. of Livestock 10000 C a ttle 8000 Horse /m ule 6000 4000 2000 0 1970-75 1980-85 1990-95 2005-07 Time Period Changes in livestock population between the 1970-75 to 2005-07 period as reported by the people of Niti valley (10 villages).
  • 12.  Pastoralism also involves important relationshipwith low altitude (Tarai–Bhabar tract) forests. Currently, the lowland experience dry conditionsfrom Dec. – May (with the exception of winterstorms) and low rainfall adversely affect the growthand productivity of herbaceous vegetation. Climate change at high altitude would affect theproduction of forage quantity and quality, increasedisease and disease spreading pests, reduce wateravailability etc. and would make these communitiesto face difficult situations.
  • 13. Sheep, goat grazing in alpine meadowsHorse, mule grazing in alpinemeadows
  • 14. (C) Forest and Timberline Vegetation Pinus wallichiana and Cedrus deodara (keystone species) usedby buffer zone villages for timber, fuel wood, medicine etc. Decrease insnowfall and rainfall probably negatively affecting theregeneration of deodar. Pinus wallichiana is regenerating and spreading faster thanother species (noticed by us as well as by villagers). The stem and leaves of Betula utilis growing in association with Abies,Rhododendron, Taxus (3300 – 3600 masl) damaged severely bydefoliators (moth/insect) since last 10 -12 years and this probablydue to less snowfall and gradual increase in temperature. Advancement of phenophases (flowering, leafing & fruiting time).Rhododendron arboretum, Allium stracheyi, A. humile,Meconopsis aculeate and Saussurea obvallata & some prominentwild edibles i.e Rubus ellepticus, Rosa webbiana and R sericea.

  • 16. D. Alpine Meadows The alpine landscape in Niti and Mana valleys is erodeddue to glacier melting, avalanches and landslides,which favour the spread/expansion of Polygonumspp. fast growing weeds. The other successful invaders found in thesehabitats includes species such as Lonicera andEphedra. The transformation of an alpine meadows has farreaching impacts on the livelihood of the traditionaltranshumant communities. The alpine meadows of NDBRcould also be impacted by rising temperature that wouldpromote the upward migration of woody plants from sub-alpine and temperate forests.
  • 17. Rate of retreat of some important glaciers in the Nanda Devi Biosphere Reserves (NDBR), IndiaS. No Name of the Glaciers Rate of retreat (m/yr) 1. Milam Glacier 16.7 2. Pindari Glacier 23.5 3.

  • 18. E. Tourism Climate change could generate both some seriousproblems but also opportunities for the tourism sector. A wider appreciation of the impact of a leisure cultureincreasing numbers of people are remaining in buffer zone ofthe reserve for much longer duration (i.e. in Badrinath, Mana,Hemkund Saheb, Valley of Flowers, Niti, Tapovan etc.).Tourism in the reserve may provide better incomegeneration opportunities as other primary and secondaryproduction sectors (i.e. agriculture, livestock, NTFPscollections) decline. Culture of the traditional communities is itself open topressure which have uncertain outcomes.
  • 19. Number of pilgrims expanded their stay as a tourists.

  • 22. Mitigation & Adaptation strategy A. Use of pack animals in reducing CO2 emissionIn six valleys the co2 savingshas been estimated as 1445 tonco2 and in terms of cost of fuelsaving to be US $ 522,800. Hence,pack animals can play animportant role in reducing theemission of greenhouse gasessuch as co2. Although construction of roads is atop priority for people from suchremote and far-flung regions,incentives should be there toencourage the use of pack animalsfor transportation.

  • 23. B. Conservation of wild biodiversity: strengthening of the protected area networkWe have a long history of plannedconservation(13.4% of its geographical area is underPAs network), our knowledge of people, biodiversity,vulnerability, and their linkages is very limited.Therefore, participatory research/ managementcould turn peoples callous/ negative attitudes topositive attitudes towards protected areas as well asimproving scientific knowledge related to potentialuses of biodiversity for coping and mitigation(Maikhuri et al. 2000).
  • 24. C. Rehabilitation of degraded forests and abandoned landsthrough agro-forestry &restoration ecology approaches ( Maikhuri et.al.2001,2003) The co2 content in the atmosphere could be decreased by bringing back carbon into biomass and soil through rehabilitations of degraded lands Turmeric cultivation
