• Highly spatial different in Rainfall Distribution• Long period Rain spell• Flat and high elevated topography – Table Mountain• Limited Gravity irrigation System – Mostly pumping

irrigation• Annual flood and drought disaster• Low fertile soil / with high percolation• Short period land utility - one crop a year

• Farmers in Northeast are the poorest Thai - average income is much lower than national average

Lessons Learned and Ways Moving Towards• Diversion after intra basin • Energy saving• Gravity• Integrated planning upstream/downstream• Incremental Steps of Development • Land and Water resource Planning• Shifting crop calendar to water availability• Water Saving strategies

• improving irrigation efficiencies• More upland crop

• People Participation • Transboundary water – MRC BDP 1 & II• Diversion through tributaries
