food security

This picture of the dessert badlands of the southwestern US makes me think about food security. It makes me question what kind of a lifeboat I can build/plan to combat a dessert like this. When I know that global warming and carbon output are messing with climate world wide, not to mention things like soil depletion, water shortages, and seed stock contamination by GMO's......there are days I am surprised the whole world doesn't look like this.
I have been looking into "Growing Green Neighbours" and possibly volunteering with them. The little flyer that I recieved talks about growing food security but I don't know if that is what they are doing. I don't know if this is along the lines of what I think of food security, and permaculture and food forests and CSA, and urban agriculture, or what exactly they are doing.
I will have to see what comes of it there is a dinner in May??? I don't know why a dinner unless it is one of those potlucks that they seem to talk about on the community notices board....That seems awfully late in the season, to be getting together. Okay I guess at least I should have all of my garden in by then and possible at least the pergola completed. That should also give me a chance to also get a couple of the double buckets set up and functioning which might be something they might be interested in if they are geared towards urban ag. I don't know if they will want to see my garden or if I will have to agree to allowing people in my garden....I don't know if I am quite ready for that.
I don't even know if I will join. I don't want to do the board thing at this point, get my hands dirty helping out no problem, sit on a board no way. I really have no idea what these folks are actually doing, the flyer that I have talks about community gardens, learning how to garden, but also about local food, food banks, community kitchens, grow a row, and "working in partnership to build community capacity" whatever that means.
I do know that the more that I feel about it the more I think that it's this harvest that it starts. That I really have to remember there are 5 priorities and everything else is just stuff......
food, water, shelter, heat and security those are the only things that truly matter.
I keep getting the feeling that the sands are running out and that there is a sense of urgency in what I am doing. Water barrels, window farms, global buckets, bake ovens, wood heat, seeds saved, good hand tools, vegetables planted, fruit planted, medicinal herbs planted, culinary herbs planted, pantries stocked, soils built up, and plans sketched out......
I hope this group is more about Gaia permaculture, food forests, and urban agriculture than about communities in bloom, it seems to be. I really hope this is a good group and nothing too political or with too many personalities because I love to garden but I am getting a little lonely doing it all by myself in my backyard. There have to be other people out there that feel the sands running too, and are trying to set up a framework that will help provide the tools for the people within this community and the farmers who live around us to succeed in building a secure network of safe food. A network that will survive peak oil, population pressures and climate change.
