Landon - it sounds like your time in the Amazon had a similar effect on you as my time in drylands. You see how truly bad it is. And I have been active in dryland rehydration for many, many years and continue to do so.
I also get what you're saying about the need to go beyond thinking locally, making personal decisions, etc. HOWEVER - the vast majority of people out there like to bemoan our fate and do little (even with their personal choices) to make change. I've seen/heard so many people whine away about the continued water issues that the SW USA is facing - yet these same people go home and water their lawns, take 20 minute showers and swim in their private swimming pools - WTH?? I've also seen people wake up to the fact that their personal choices matter and come to advocacy through that enlightened state simply because they have seen that they are making a difference and seen the power of that change, rather than sitting idly by and adding to the ceaseless blather of "OMG what are we going to do!?!?!" That, to me is a monumental waste of time. Give me one person who shortens their shower by 5 mins, empties their dishwater on a tree or uses non-toxic soaps and I am delighted.
Finally - advocacy is HUGE - I am in complete agreement with that. However, I would request that if you are going to advocate for advocacy - be as clear and helpful about it as possible and list some organizations that folks can get behind and why you think these are good organizations - especially as you seem to have a lot of experience in this arena. That would go a long ways towards engaging and directing efforts.
So I will do my own part here.
If you are interested in the INCREDIBLE difference water harvesting can make in drylands - no matter where you live - please be sure to check out Watershed Management Group out of Tucson, AZ. They are a top ranked non-profit and do exceptional work both in the SW USA and in various parts of Asia and Africa. And they've done a lot to change water policy as well. If nothing else, make a donation. Arizona is on the cutting edge of water harvesting technology and it is being spread worldwide to halt the spread of desertification and regenerate arid lands. It's incredible work and I'm glad I live where I live so I can be part of it all. They also offer well recognized training in water harvesting with their
Water Harvesting Certification (some scholarships available), and advanced training like
urban stream restoration and
green infrastructure.
