I have the problem to view some things as racional and others as not. The racional things should be easy to solve, because the reason should be enought. In my opinion, most of the issues concerning agriculture are problems but problems with reasonable solutions.
I can't explicit a solution to a concrete problem but I can try to write a few steps for each person solve it.
1.Identify the problem,
2. Identify the Company/Person who benifts with the problem
3. Denunciate it/him (authorities, syndicates, ONGs, etc)
4. Search to better way to use agriculture there
2. Talk to specialists to the subject (meteorologists, enviromentalists, old local farmers, etc.)
