Adapting livestock production systems to climate change in Nepal: Challenges and opportunities

摘要

To assess climate change impacts and identify challenges and opportunities for livestock climate change adaption, we conducted a comprehensive study in the Thulokhola watershed of Nuwakot district in Nepal from June 1, 2011 to January 31, 2013. We established nine community livestock groups (CLGs) consisting of 51 members and trained the CLG members in daily livestock record keeping and monitoring surface water quality. Monthly fecal samples from 50 cattle, 50 goats, and 50 buffaloes were collectedforthe determination of gastrointestinal parasites. Soil and fodder samples were also collected and analyzed. Group discussions, Participatory Rural Appraisals, and full-fledged household survey of 97 households were done. A survey of 41 water sources inthe watershed was also conducted. While 85.3 % of the water sources have either dried up or decreased in flow in recent years, drought conditions had great toll on agricultural production. Prevalence rates of helminthcs on goats, cattle, and buffalo was53.8%, 31.32%, and 23.52%, respectively, and animal deaths were remarkably high. Declining pregnancy rates on livestock along with waning supply of fodder and forages and poor soil quality were additional major problems. Although local communities haveundertaken several measures including adding new breed, destocking, purchasing fodder and forages, and planting grasses for livestock climate change adaptation, the problems of animal health, breeding conditions, soil fertility, forest degradation, increasing women workload, and water shortages were largely unaddressed. Opportunities for livestock climate change adaptation in Nepal include agroforestry intervention, groundwater utilization, rainwater harvesting, enhancing feed efficiency, and communitycapacity-building.
