Biogas is the core idea which connects ecosystem and social system basically in my diagram. Biogas impacts both ecosystem and social system in many ways and also ecosystem and social are interacting each other. First, biogas is reducing smoke in the house that helped to reduce air pollution. Before biogas, people used wood burning stove which is harmful for family health and also to get a fuel, children helped to get a wood which resulted late for school and miss breakfast this is positive feedback loop. This will cause more problems. Development of technologies, it creates jobs and activates economy. Wood burning stove might have low resilience than biogas generation, because the resources are limited. On the other hand, the resource for biogas, manure is pretty much never running out this mean, biogas is more stable than wood burning. So basically, diagram shows that ecosystem and social system has close relationship.

Comparing my diagram to figure 1.5, the contents are similar to each other but the linkages are different. If we see the figure 1.5 all the components are linked each other in the system. But my diagram, some links are across the system and not linked all components in the system. the big difference is while they linked whole systems in figure 1.5, my diagram linked each individual components.  Both diagram separate ecosystem and social system it is the same part. By comparing two diagrams we can learn what other people think and other perspectives.
