Hello Pamela and all,
There is an apocryphal story that shows why farming is not attractive around the world, among poor populations. They are usually that way because of practices like this: A Kenyan herder and his brother decided to grow potatoes one year. When the potatoes were ready to harvest, a buyer came and said, "I'll give you $2 for 200 potatoes in a bag. You can either take my $2 or watch your potatoes rot in the ground or turn green above the ground." The potatoes cost $2 to grow, and after a series of huge markups by the buyer and other middlemen, a street vendor would sell two potatoes, fried, for $2 -- a 100 : 1 markup between grower and consumer, all of it outside the rural area. That is another major reason why rural economies are broken, and populations flee to the cities.
Joy Tang and I, and Jeff or Micheal, met him at Stanford University, where he was a Stanford Digital Vision Fellow, designing an electronic device that could be inserted under a cow's skin, and use near-field communication to keep records or report on the cow's health, and to identify it and its owner if it was rustled (stolen).
That the abuse described above is universal is indicated by how the Idaho potato brand got started in the UNitd States, and this shows one of ways in which youth can be encouraged to do what they do naturally and make a difference that is important -- get together with their friends and do stuff that's interesting. When the buyers tried to pull the same stuff on Idaho potato farmers in the 1880s, the farmers cut pine trees and used the trunks to make upside-down V frames over dry washes (gullies). Then they covered them up with piles of hay, and put doors at each end. That gave them above-ground root cellars that would keep potatoes fresh for months, and they would put the potatoes in at the top and take them out at the bottom, so they had a first-in, first-out inventory system. Now they could tell the buyer to go away, and come back when he was ready to be reasonable, and they could also organize wagons to take the potatoes to market and sell direct, bypassing all the middlemen except the grocer, and making a fair income for their efforts and the use of their lands.
Today, it's becoming possible to ferment unsold mangos and use the alcohol to power an old truck, then use the mash (left-overs) from fermentation to grow mushrooms. In about 2 years, the price of batteries will probably be so low that it makes sense to use solar energy to make electricity and power a battery electric conversion to run a truck, even for long distances. At that point, instead of fermenting the leftover mangos, they can build a cob (monolithic adobe -- clay, sand, long straw and water mixed, with the straw in each course pounded into the course underneath it before that one gets hard, so it loops between the courses, tying them together with its aggregate tensile strength -- it resists earthquakes) round wall, put a tall pole in the middle, run long joists from the top of the center-pole across the top of the wall, all the way to the ground and into it enough to anchor it. Then put lots of insulation over the top within the wall, and whatever covering may be wanted outside the wall (for tool storage, processing, or whatever). Then set up bins or shelving or whatever is appropriate, and make or get a solar-powered refrigeration system (or convert one from gas power) to chill the inside, and store the mangoes (or whatever needs refrigeration to keep) in there. (I developed the cob wall with conical roof design after the huge earthquake in Afghanistan.)
You've done with locally available, mostly free materials and your strength and care, what farmers in California do with huge concrete buildings that cost millions of dollars to put up (I've seen one). To make it more efficient, train some older children to monitor it and make sure it is working correctly.
The most important role of ICTs is to share such knowledge with people who did not have access to it previously, and empower them to achieve things they never could before, since colonialism broke the social structures that maintained prosperity in communities. Another role is to reach out to NGOs and micro-lenders to loan the money to help pay for the equipment you need. You can repay it with the money you earn by getting a fair price for your crops -- even if you have to store them and work out a way to transport them to market. All of this is easier, by the way, if you form a cooperative!
It's also important to know what is possible on a farm, however small.
A story on the GrowBioIntensive website years ago told of a woman who left her community with her 4 children and bought a fifth of an acre to have a place to bury her children when they starved or died of malnutrition-complicated disease. Someone told another farmer, who told her about Manor House, in Northwestern Kenya, which has taught people how to grow food the BioIntensive way for decades. She went there, learned how to do it, returned home, and soon was growing enough food to feed her children and have a small cash crop as well! That's feeding 25 people per acre.
Joy Tang and I got to know a couple who had worked at the National Museum of Nigeria. The husband told me that he grew up in an extended family of 200 people in Ife (southern Nigeria). As the person above said, everyone had a trade in town and also a family farm. His family had had the farm for generations, and they produced all their food and fiber on it -- on all two acres of it! That's food and fiber for 100 people per acre! He said they had it all covered with 3-foot high mounds, and each mound had a different combination of strains of different species, with everything planned and worked out over the generations, like large-leaf plants shading the soil at the bottom, and roots of companion plants intermingled, for incredible resilience, as well as productivity.
That is what was lost across Nigeria when the nation went crazy after the discovery of oil, and most of the farms were abandoned by people seeking wealth, when they already had a form of wealth beyond compare anywhere on the planet. But as a famous chief in America said, eventually people will learn that they cannot eat money.
This leads to the final answer to your question: when you can show video of people learning to grow their food and be free and prosperous in the old sense, and sharing enough technology to make things easier in the face of corruption and disease, yet live in harmony with nature again, and marry and raise healthy children at home on the land, then family food gardening will be seen as the diamond that it really is, by young people trying to figure out how to have exactly those results in their lives.
