There are places in the Caribbean with high altitude terrain. Within these areas you will definitely find hillside farming, terracing and the like. Well here is a technology that can be quite effective. Its called Fog collectors – These are vertical panels of polyethylene mesh that collect water from the surrounding fog, in high altitude areas and channels it to a storage tank. Thereby water that may be difficult to access because of the terrain, is easily farmed from the sky!
This is a novel idea and as you’ll see at this video ( http://www.youtube.com/watch?v=njRtL8lN2b4) provides much valuable water for communities and its agriculture. You can get more information at http://www.fogquest.org/
