The provided system diagram that I’ve made is relatively simple to what other students might have and also from Marten’s diagram. What I’d like to show in the diagram were mainly how the biogas technology impacts both the ecosystem and the social system of the part in India which applies the biogas system. This invention produced two major products; methane gas and slurry. Both of these outputs brought various effect to fore-mostly the ecosystem, then affecting the social system as well. The production of methane gas leads to less environmental pollution and also reducing deforestation due to the people having an alternative energy choice for cooking. This in return will benefit the people health-wise and allow the children to go to school instead of gathering fuel. The slurry, on the other hand will help local farmers to fertilize their soil and grow healthier crops. At the same time, the slurry provides a certain group of the population (mainly women) with job opportunity by processing them into fertilizers to sell to farmers. Both the farmers and the women will gain economic profit from this.

For the most part, this diagram is much simpler and straightforward than that of Marten’s. It is similar in a way that both charts are divided into two major divisions- social system and ecosystem. Also, this diagram shows the effect that all outcome from the ecosystem side eventually leads to a healthier ecosystem, which isn’t shown in Marten’s diagram. Comparing the two diagrams, I think we could all learn more from the more complex relationships appearing on Marten’s illustration because he listed along the products and processes that goes along in the exchange of points such as cooking fuel, cut wood or put in biogas generators.

The system diagram above conveys the Human-Environment System by displaying the vast interactions of the social system and ecosystem within the biogas revolution in India. The diagram shows both the positive and negative impacts of the technological development of biogas culture. The wood burning culture had created poor health effects due to wood burning, it forced child labor for collecting firewood, and caused deforestation. The new biogas culture allowed for a cleaner environment, less health effects, and less deforestation. It also created new jobs and wealth which allows the human population to flourish.

In comparison with the Marten system diagram there are similarities and differences. Both the Marten diagram and my own showcase the various interactions of the Human-Environment system. They display the affects that human decisions have on the environment and the way the environment affects human decision making. They differ in that Marten has more specific cross interactions between the two. Mine could have used more wording in the cross between to be more complete. I think these similarities and differences help to showcase where one puts emphasis on certain decisions and where others may be overlooked. I think it is important for things to be analyzed from more than one perspective so that we get a more complete picture of the interactions from a research perspective.

The core idea behind my diagram is to show how with the introduction of the Biogas Wells, the Indian people are able to use the resources that are more readily available to them (such as cow manure) to provide themselves with a cleaner and more efficient way of cooking, as well as improve their farming. Like the video, I also show how the slurry produced by the biogas wells is mixed into compost so that it may be used by farms.  This in turn allows the farms to produce improved crops as well as more of them.  These crops can then be sold at market where the population may purchase them, and the cycle repeats. I think one key aspect of the Biogas Wells is how it made the process of cooking not only cleaner, but it improved the cycle overall by making it more efficient.

Compared to the diagram in “What is Human Ecology,” the two diagrams share similar traits under both types of systems.  Mine does not include the need for child labor, since I based it off of how the system would be after the Biogas Wells were introduced.  My diagram includes an Economy section under the Social System, since the farmers were able to sell more crops due to the slurry compost mix produced by the Biogas Wells.  One thing that I think we can learn from my diagram is that due to the increased amount of crops produced, the population is able to purchase more of them. Biogas_tjg5287
