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

因为这项研究的目的是监测大规模沼气干预对印度北阿肯德邦森林更新的影响。在本财政年度，我们开展了以下工作：1.利用陆地卫星数据绘制研究区森林覆盖变化图。这些数据有助于根据森林覆盖率的变化和沼气植物的干预进行实地调查和结果的验证。2.为了解沼气是否为薪材的主流解决方案，我们进行了实地工作和与当地人的重点小组讨论。在讨论中，人们提到了沼气的各种好处。受访者表示，沼气作为替代能源在一些地区并不成功，原因有很多，例如：动物数量减少导致足够动物粪便的产量减少、沼气工厂的设计/技术不佳、运行工厂的培训不佳、季节性、迁徙等。我们还走访了人们仍在森林中收集薪柴的地方，并对他们进行了访谈，以找出原因。3.我们收集了各种沼气工厂及其在研究区的位置的数据。这些数据对于利用遥感数据获取森林生物量更新的定量信息是有用的。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.
