This diagram depicts the socioeconomic and economic benefits of biogas usage in India. Prior to the introduction of biogas in India, wood was widely used across the country as a source of fuel for cooking and power. The high use of wood resulted in mass deforestation, which resulted in poor and loose soil content. When flooding occurred, the soil was usually washed away and was unable to replenished as fast as areas where soil remained in tact. This made an impact on rural areas — a hard impact. With the implementation of biogas generators, it uses natural resources already made available that do not have as significant of an impact on the environment than the use of wood. By the use of animal dung, the dung sits out during the day and eventually begins to produce methane. It is place into a slurry underground and the methane is then used as a source of gas in the rural households. The slurry is then recycled into rich fertilizer for farm fields. Of which, this fertilizer is sold on the market to farmers. Therefore, poorer households have doubled their income, if not greater, and are able to support their families and or kids’ studies.

As for my diagram compared to the figure in the reading: “What is Human Ecology?”, there are similarities on a relevant scale. The scale on the Marten reading shows two different diagrams depicting the social system and ecosystem. Within each are networks interconnected with respect to their significance of impact on society and the ecosystem. These two diagrams are then interconnected by the use of energy, material, and information from both systems. The diagram I devised integrates both social and ecological systems into one. You cannot have impacts solely on one system without impacts on the other, whether it is good or bad. I think in this case, it is a positive and negative feedback depending on the subdivisions within this diagram are connected to one another.

HI Harrison! I’m Lisa! I really enjoyed reading and viewing your diagram. I can definitely tell that you put a lot of time and effort into it. Even though I did not talk about deforestation in my post, I could still see some similarities to how the environment effects India and vise versa. It was great to see the connections between deforestation and a healthy habitat. I enjoyed reading your post and would love for you to check out mine!

Hi Harrison! My name is Emily and I found your description to be very knowledgeable. I like how you started with the problems of mass deforestation resulting from the need for wood. This is vital to include in the larger picture of using the biogas generator. Compared to my diagram you added a few different aspects, such as wildlife preservation. This is a very good point and something I did not think about. However, we both included the economic advances that this fuel source can bring.
