I like the concept of cheap, efficient food driers. It makes food last longer giving more time to deliver to markets. New and more profitable markets can therefore be developed with good product packaging and market channels developed. Also see good potential in providing dried fruit products to drink and ice cream makers. Thanks Juan.

While I support the use of technology to build some solutions, I am very wary of focusing on tech in situations where it may  not be effective. In rural Vietnam, while people generally have reasonable access to Smartphones, they almost entirely rely on 1 to 1 practical demonstration to learn things. These are not people who have access, or knowhow to effectively use the internet for learning and are not motivated to do so.
That is why our project to diversify farmers crops & land use proposes establishing local demonstration farms where practical training in all establishment, operational management can be done so farmers return to their farms knowledgeable and ready to participate.
Also,, in most cases, individual farmers are not prepared to operate on a scale to  determine their own markets. There is still a great need for middlemen to develop markets, operate the collective marketing areas need to become effective. This should be separated from the limited government assistance which only covers certain crops like rice, coffee etc, and is always based on a government subsidy price related on often excess product storage and therefore lower international prices. Farmers previously locked into such a system need to  diversify into much more valuable crops that have a high local demand. Greater farm productivity, reduced delivery logistics to market, and very marketable organic produce sets a far greater revenue return to farmers than before.


Malcolm commented on Fish & Rice farming

Low-tech aquaponics involve the simultaneous cultivation of an aquatic species and plants in a system. There is a reduced need for fertilizer because the waste of the aquatic organisms are used by the plants as nutrients. This type of aquaponics has been historically implemented for thousand of years in China and other places that have large swampy tracts of land. The most commonly implemented one is a Tilapia-Azolla-Rice culture. Tilapia are one of the most efficient species of fish and can put on close to one pound of fish flesh per pound of fish food they eat; the Azolla is a floating aquatic macrophyte that acts as supplemental food to the fish. The rice can be harvested directly for human consumption. This solution requires investment in education; training the local farmers is the key to its successful implementation. The method holds particular promise where conventional agriculture is not viable due to the excess of swampland and lack of soil. Aquaponics eliminates the need for expensive fertilizers while reducing the environmental impact of growing fish, as the plants naturally filter the water as they take in nutrients.
In addition, growing fish using aquaponic systems requires less water and land than traditional methods of production.This solution will provide malnourished people with a source of protein, a nutrient that is crucially important for maintaining a healthy body, but is often unavailable to people in impoverished areas
