Dear,
I come through this question to divulge my work.
Do you think that studies like this could contribute to the conservation of aquatic ecosystems and reduce social problems in the Amazon?
Sincerely,
Rangel Santos
Dear Rangel,
This question reminds me of those people who want to have "the recipe" for happiness...
It is obvious that all man's modifications of natural systems have some impact. Reservoirs... have many! What are these impacts? This depends on who analyzes it and the scale (time and space) that is used.
Your work with the perception of fishermen is very good, especially because it presents the perception of a human group that is usually ignored or undervalued in dam projects.
But, of course! it is only the perception of one of the human groups, and on a time/space scale. There are many other variables to consider, besides fishing and changes in biodiversity: Is energy really necessary? What will we do with that energy? Will it be applied to the "sustainable development" of local communities? or will it be used for the growth of the metropolises?
In another sense, we all know that "Energy is neither created nor lost..." So, the electrical energy that I produce with the dams, is energy that the river loses to maintain its hydro-geomorphological model and to feed the organization of the river system.
So, the POLITICAL decision to make a reservoir always entails environmental deterioration. We can only advise on how to diminish the impacts, or achieve compensation mechanisms, in some cases.
Best wishes,
JJ
As suggested, many potential impacts from dams and the need to transmit power to distant areas. You might consider more localized water wheels. Article Gravity water wheels as a micro hydropower energy source: A ...
Dear colleague, congratulations on your recent article publication! The answer of your question is far beyond the results of the article. The nowadays Brazilian federal government are playing against environment, science and education. In this scenario a single scientific study would have no significant contribution for conservation or social issues in Amazonia.
It's a recurring question like other questions in many science areas. I think that all of our efforts do will not be enough to change anything from the perspective of currently governments!
