2. SATLUJ PUNJAB–UPPER CATCHMENTS Surface water resources inflow to Bhakra -major gap in information To yr: 2050 Temperature + 2 degree C –higher in the upper catchment than on plains, may go higher Precipitation and runoff some increase in precipitation, poor accuracy Short term surface water –to 2020 no significant change; increased melt flows from glaciers, reduced melt from snow. • Medium to long term from 2020 • insufficient data to confirm trend • gradually effects of increased glacier and snow melts will affect inflows to Bhakra. • Bhakra can to an extent provide a buffer but glacier loss will be significant. • Require: glacier mass, snow and glacier melt response assessments

3. SATLUJ PUNJAB –LOWER CATCHMENTS By mid century: + 2 degree C Precipitation:+ 10-15% mainly runoff, limited recharge Evapotranspiration: little change Increased variability of rainfall patterns • Groundwater 45% above sustainable levels • Sustainable GW-key to buffer against CC • Conjunctive SW and GW management

4. WATER QUANTITY • very limited surface water, groundwater is the key resource and • groundwater overexploitation in some parts • the yield of surface water and groundwater is however more than requirements, • most of this water is lost as the rainfall during to 3-4 months of rainy season WATER QUALITY • WQ issues Kshipra river and some tributary streams very heavily polluted and go dry for periods-no base flow KHIPRA SUB BASIN MADHYA PRADESH Climate Change: To 2050: Temperature: + 2 degree C Precipitation: + about 15% increase in annual rainfall +23% in monsoon rains some decline in the non monsoon rains. Increased variability of rainfall patterns • Present Issues • WATER QUANTITY + WATER QUALITY • limited surface water, groundwater is key resource • groundwater overexploitation in some parts • yield of surface water /groundwater more than requirements, • Most water is lost during rainy season • WQ issues river and tributary streams very heavily polluted and go dry for periods-no base flow

5. CAUVERY DELTA TAMIL NADU Climate Change to 2050: +2 Degrees C No significant change in annual rainfall South west monsoon would reduce by 10% North east monsoon would increase by 10-15% Increased variability in rainfall patterns Sea Level rise of 0.3 metres • PRESENT ISSUES • limited surface water during SW monsoon • erratic, very intense NE monsoon causes flooding. • saline intrusion, low lying land is unable to drain. • groundwater used to supplement surface water -issues of overexploitation and salinity intrusion. • parts of the coast are eroding river mouths suffer from blockages causing problems for fishing and flooding

6. Q: How to plan for climate change? • Need a systematic WR planning process for sub basins. • Strategic Planning to follow IWRM, participative and iterative • Plans must be mainstreamed into departments and districts for implementation • CC. projections presently not adequate to make concrete planning decisions-but can support strategies and general direction.
