  9. 9. IMPACT OF CLIMATE CHANGE ON AGRICULTURE
  10. 10. Trend of temperature changes in Kathmandu (Max)
  11. 11. Glacial Melts Nepalese glaciers are retreating at a rate of about over 33 m per year. As many as 20 lakes are at risk of outburst
  12. 12. IMPACT OF CLIMATE CHANGE IN NEPAL Annual total rainfall fluctuated, but temperature gradually increased Week to record 100 mm rain but now in hours. Numbers of such events were 55 in a year in ‘70s and now 90  Numbers of dry days temperature over 25 o C is increasing
  13. 13. DISEASES INCIDENCE DUE TO CLIMATE CHANGE Rice - blasts, sheath blight, and brown spots Wheat- stem rusts such as yellow rust, black rusts Maize – foliar blight (dollar disease) Lentil and chick peas- Botrytis Gray Mosaic Virus (BGM) Lentil- Lentil blight (organisms not known) Potato- Late blight Citrus- citrus cancer, greening virus, powdery mildews
  14. 14. MITIGATION STEPS Biogas plants establishment Conservation agriculture-Zero and minimum tillage Organic farming and reforestation -carbon sequestration Breeding crop varieties suitable for CC Jatropa plantation for bio-fuels
  15. 15. CONCLUSION  Temperature rising & hydrological regimes seriously affected Nepalese agriculture  There could be some advantages to summer crops but harmful to the winter crops  Overwintering of pests & diseases increased stresses to crops 
  16. 16. CONCLUSION.... Breeding short duration, tolerance to biotic and abiotic stress is needed Limit the use of fossil fuel but not in expense of food crops.
  17. 17. Flooding in Nepal Koshi River Floods in 2008 destroyed 250,000 homes in 1600 villages  In the year 2010; 1600 family. Displaced due to floods and Landslides in 43 districts across the country within more than two months period
