The core ideas behind my biogas diagram focused on the components affected by the introduction of biogas systems as alternative fuel for the rural community in Bangalore. The diagram shows the chain effects between the ecosystem and social system.The introduction of biogas system begins with Vidya’s story of his childhood, which was filled with memories of his mother using firewood for cooking and its effects. The hazards of smoke inhalation and the challenges of collecting of firewood were some of his mother’s hardship. For these reasons, Vidya began this endeavour of improving life for the rural areas by introducing biogas generators. The biogas technologies has a great impact to the population in the rural areas plus promotes several sustainable factors for the community. As indicated in my diagram the biogas provides clean sustainable fuel as well as; promoting education, health benefits, income from sale of the compost, trees are saved, coffee farmers have an increase and better quality yield from the compost also clean and safer kitchens. My diagram and the figure 1.5 in Marten’s reading are quite similar due to the fact that both diagram show the ecosystem and social system relationship as well as feedback between the components. My diagram differs because the biogas in my scenario is generated from the animal waste only also Marten’s diagram shows a direct impact of biogas system to the birth rate. There are similarities and differences due to the background narrative for the diagrams. Therefore basic underlying components will be similar and specific effects vary from community to community.
