  • Climate Change and Water Resources Dr. N. Sai Bhaskar Reddy, CEO, GEO http://e-geo.org 16th August 2012Center for Climate Change and Environment Advisory (CCCEA) Dr. MCR HRD Institute of AP, India
  • Present carbon cycle Storage and flux of carbon (in billions of tones)SPEED OF EXCHANGE PROCESS Very fast (less than 1 year) Fast (1 to 10 years) Slow (10 to 100 years) Very slow (more than 100 years)
  • Human activity influence
  • Variation of the temperature on Earth
  • Temperature trends (1976 to 2000)
  • Precipitation trends (1900 to 2000)
  • TEMPERATURE PRECIPITATIONS5 degrees = What separates us from the last glacial era (-15 000 BC) Models’ forecasts : +1,4 to +5,8 degrees by 2100. Source : IPCC/SRESA2
  • Visual impact of Climate Change
  • Impact of Climate Change on society…Katrina, Rita, Stan, Wilma… Climate change will cause heavier tropical cyclones.
  • Cost of extreme weather events
  • Less visual but with major impact Agriculture and food security Consequences of Crop yields, irrigation demands... climate change: Forest Composition, health and productivity... Water resources Water supply, water quality... Coastal areas Erosion, inundation, cost of prevention... Species and natural areas> Temperature increase Biodiversity, modification of ecosystems...> Sea level rise> More rain Human health Infectious diseases, human settlements...
  • VulnerabilityVulnerability to climate change is the risk of adverse things happeningVulnerability is a function of three factors: Exposure Sensitivity Adaptive capacity
  • Exposure•Exposure is what is at risk from climatechange, e.g., – Population – Resources – Property•It is also the climate change that anaffected system will face, e.g., – Sea level – Temperature – Precipitation – Extreme events
  • Sensitivity• Biophysical effect of climate change – Change in crop yield, runoff, energy demand• It considers the socioeconomic context, e.g., the agriculture system• Grain crops typically are sensitive• Manufacturing typically is much less sensitive
  • Adaptive Capacity• Capability to adapt• Function of: – Wealth – Technology – Education – Institutions – Information – Infrastructure – “Social capital”• Having adaptive capacity does not mean it is used effectively
  • Vulnerability is a Function of …• More exposure and sensitivity increase vulnerability• More adaptive capacity decreases vulnerability• An assessment of vulnerability should consider all three factors
  • Adaptation“adjustment in natural or human systems in response to actual or expected climatic stimuli or their effects, which moderates harm of exploits beneficial opportunities”(Third Assessment Report, Working Group II)Includes “actual” (realized) or “expected” (future) changes in climate
  • Adaptation (continued)Two types of adaptationAutonomous adaptation or reactive adaptation tends to be whatpeople and systems do as impacts of climate change becomeapparentAnticipatory or proactive adaptation are measures taken toreduce potential risks of future climate change
  • SL framework: Determinants of adaptive capacityLivelihood ExamplesresourcesHuman Knowledge, SkillsSocial Women’s savings and loans groups, farmer- CBOsPhysical Irrigation infrastructure, seed and grain storage facilitiesNatural Reliable water source, productive landFinancial Micro-insurance, diversified income sources Policies, institutions and power structures

  • Indian poverty• Poverty is widespread in India, with the nation estimated to have a third of the worlds poor. According to a 2005 World Bank estimate, 41.6% of the total Indian population falls below the international poverty line of US$ 1.25 a day (PPP, in nominal terms 21.6 a day in urban areas and 14.3 in rural areas).[1] A recent report by the Oxford Poverty and Human Development Initiative states that 8 Indian states have more poor than 26 poorest African nations combined which totals to more than 410 million poor in the poorest African countries.[2]
  • What is being done and how effective is it?1. Communities continuously finding better options to reduce their vulnerability2. Few responses decrease the sensitivity of the system3. Majority are short-term fixes - reduce vulnerability temporarily but decreases the resilience of the system
  • Climate Changes in India• Increase in surface temperature by 0.4 degree C over the past century.• Warming trend along the west coast, in central India, the interior peninsula, and northeastern India.
  • Climate Changes in India• Cooling trend in northwest India and parts of South India.• Regional monsoon variations: increased monsoon seasonal rainfall along the west coast, northern Andhra Pradesh and North- western India, decreased monsoon seasonal rainfall over eastern Madhya Pradesh, North-
  • Climate Changes in India• Observed trends of multi- decadal periods of more frequent droughts, followed by less severe droughts.• Studies have shown a rising trend in the frequency of heavy rain events and decrease in frequency of moderate events over central India from 1951 to 2000. 26
  • Climate Changes in India• Records of coastal tide gauges in the north Indian ocean for the last 40 years has revealed an estimated sea level rise between 1.06-1.75 mm per year.• The available monitoring data on Himalayan glaciers indicates recession of some glaciers. 27

  • WATERSHED DEVELOPMENT PROGRAMME (WDP)Improve and sustain productivity and production potentials of the dry/semi-arid regions of India through adoption of appropriate production and conservation technologies.Meet the needs of local rural communities for food, fuel, fodder and timber. Improve all types of lands, i.e., Government, Forest, Community and Private Lands falling within a watershed.
  • WATERSHED DEVELOPMENT PROGRAMME (WDP)WDPs, in short: A holistic approach to improve and develop the economic and natural resource base of dry/semi-arid/fragile regions. In a watershed development program the watershed is the unit for development rather than political or administrative boundaries
  • WDP Activities• i)Land Development: Levelling and terracing, improving soil quality and productivity; and watershed reclamation.• ii)Water Development: Promote in situ water harvesting and conservation, establish percolation ponds and open wells, tanks, small reservoirs, and improving water quality.
  • WDP Activities• iii)Enterprises/Activities: Evolve appropriate farming systems, encourage a crop mix of high value/high yield crops, social/agro- forestry, other income-generating activities like dairying, poultry-keeping, etc.
  • Some Illustrations of Benefits of WDPs• -Replacing seasonal/annual crops with agro- silvi, agrohorti, silvi-horti; systems on hill slopes/degraded lands. Benefits: reduce soil erosion; arrest surface run-offs.• -Training water to store excess water run-offs in farm ponds/percolation tanks. Benefits: improve groundwater recharge.• -Construction of earthen or vegetative bunds or barriers to surface run-offs in a watershed. Benefits: help in moisture conservation.

  • MGNREGA• National Rural Employment Guarantee Act2005 (NREGA)• Act guarantees 100 days of employment in a financial year to every household• a social safety net for the vulnerable groups and an opportunity to combine growth with equity• Structured towards harnessing the rural work-force, not as recipients of doles, but as productive partners in our economic process• assets created result in sustained employment for the area for future growth employment and self-sufficiency• Operationalised from 2nd February, 2006 in 200 selected districts, extended to 130 more districts in 2007-08.• The remaining districts (around 275) of the country under the ambit of NREGA from 1st of April, 2008
  • Agriculture• India ‘s population is 1.21 billion in 2011. 67% are rural. Majority are in agriculture.• Importance of agriculture in Indian economy. Although it contributes only 15% of GDP, the share of workers is about 55%.• Marginal and small farmers dominate• Major crops are rice, wheat, maize, coarse cereals, groundnut, cotton, sugarcane, fruits and vegetables• 60% of cultivated area is rainfed as only 40% of area is under irrigation.• Rural poverty is 41%in 2004-05.• Agriculture is a ‘State Subject’. In other words, the policies of provinces are also important
  • Climate Change / Variability in Semi-arid regionsPrecipitation is less thanpotentialevapotranspiration.Low annual rainfall of 25to 60 centimeters andhaving scrubby vegetationwith short, coarse grasses;not completely arid.
  • Climate Change / Variability in Semi-arid regionsClimate Variability and extremes are anexpected characteristic of semi-arid lands.The people vulnerable to droughts, whichtrigger frequent subsistence crisesIncreasing cropfailures, dislocation, famine, poverty, increasesstratification and the social inequities.

  • Biocharculture Biocharculture is the process of using Biochar, including cultivation of crops• Biochar is the charcoal produced from carbonaceous source material. Sink for atmospheric carbon dioxide in terrestrial ecosystems• Biocharculture is one of the means to integrate for sustainable cultivation and carbon sequestration.• Biochar is usually produced at around temperatures 300 to 600 degrees centigrade for example as found in the common biomass cook stoves.• Because of its macromolecular structure dominated by aromatic C, Biochar is more recalcitrant to microbial decomposition than uncharred organic matter
