インド・ウッタラカンド州における大規模なバイオガス導入が森林再生にもたらす効果

研究的目的是监测大规模沼气干预对印度北阿坎德森林再生的影响。在本财政年度，我们进行了以下活动：1.利用Landsat数据绘制研究区的森林覆盖变化图。这些数据有助于进行实地调查，并根据森林覆盖率的变化和沼气厂的干预验证结果。2.实地工作和与当地人的重点小组讨论，以找出沼气是否是一个主流的解决方案，为薪材。在讨论中，人们提到了沼气的各种好处。受访者指出，由于各种原因，沼气在某些地区作为替代能源并不成功，例如：由于动物数量减少，沼气厂的设计/技术差，操作工厂的培训差，季节性，我们还访问了人们仍然从森林中收集薪材的地方，并采访了他们，以找出原因。各种沼气厂及其在研究区的位置。这些数据有助于利用遥感数据获取森林生物量更新的定量信息。基于PALSAR的生物量估计正在进行中。

As the aim of the research is to monitor the impact of large-scale biogas intervention on forest regeneration in Uttarakhand, India. In this financial year, we conducted following activities.1.Mapping forest cover change using Landsat data in the study area. This data is useful to conduct a field survey and validation of results based on change in forest cover and intervention of biogas plants.2.Fieldwork and focused group discussion with the local people were conudcted to find out whether biogas is a mainstream solution for fuelwood. During the discussion, people mentioned various benefits of biogas. Respondent mettioned that biogas is not sucessful in some areas as an alternative energy source because of various reasons such as: reduction in the production of enough animal dung because of a decrease in the number of animals, poor-design/technology of biogas plant, poor training to run the plant, seasonality, migration etc. We have also visited the places where people are still collecting the fuelwood from the forest and interviewed them to find out the reasons.3.We collected data on various biogas plants and their locations in the study area. This data is useful to get quantitative information about forest biomass regeneration using remote sensing data. PALSAR based biomass estimation is under processing.
