Subsistance Farmers: possible solution to starvation

My wife was telling me about a program she listened to on NPR radio about an American?
who went to Nepal and asked subsistence farmers there what would help them? What he found from asking them was that they would be better able to solve the problem than in any other way that has been tried yet with maybe 25 to 50 dollars. This money invested into a 50 gallon drum that they could fill with water and a drip system enabled them to increase their yearly income from around 50 to 70 dollars a year to 70 to 100 dollars a year. They were able by carting or hauling or piping water to this 50 gallon drum to grow without rain, something they had never been able to do before and earn 1/3 more per year by growing vegetables out of season. This sort of thing done through microbanking could be done in third world nations around the world to make up some of the lack of grain caused primarily by droughts and weather changes. In this way microbanking for subsistance farmers could help save the starving masses by growing food to sell to the hungry. This would also tend to bring down the cost of food slightly worldwide and make all people who eat food happier.

Another idea straight out of World War II is Victory Gardens. During World War II when most of the able bodied farmers were off fighting in other countries, everyone left here in the United States started growing vegetables to eat and sell so everyone got enough fresh food. It looks like it's time for all those with even a backyard and low cost enough water around the world to start doing this again so food prices drop. Also, by growing organic food you can help feed neighbors and friends and reduce the gasoline and diesel usage in your countries by growing organic and buying and selling or giving away food locally as much as possible thereby reducing oil and diesel usage in shipping food. Also, if the soil is uncontaminated you are growing in what you grow you can also oversee to be as healthy as possible. If you grow it you will know exactly how healthy it is. No one will have to tell you.
