A recent consultancy I performed related to the horticulture sector in NW Cambodia highlighted some impressive advances in production techniques and incomes for small holder farmers.
Previously traditional techniques which included animal based tillage, and hand irrigation were not sufficient to raise the incomes of many small holders. They had little alternatives though considering their lack of access to improved techniques and knowledge. This changed when an international agency began operations in the region to improve the production techniques of small holders in order to improve the livelihood prospects of these rural people.
The use of plastic film mulch, and drip irrigation has improved productivity to the point where the owner of this 3000m2 field of a local variety of eggplant provided her with up to $10,000. The long growing season of the eggplant ensured she was able to get an income over a longer period of time.
