Every summer in Vietnam, if one opens local news outlets, one would often see a wide range of media coverage on the government’s effort in having to bail out many farmers because of the large surplus of their produce. To name a few, there are pineapples, turnips, shallots, bananas, etc. If the government does not intervene, most of the perishable produce will go to waste and farmers who do not manage to at least breakeven with their sales will go bankrupt. This particular problem has been persistent for a number of years despite the government’s continuous efforts in warning the farmers about overproducing and exceeding the market’s demands for certain commodities.
CEL’s survey also revealed that “a large majority of farmers lack access to credit that would facilitate investments in improving currently poor production and harvesting conditions (e.g. more efficient tools that reduce food damage during harvesting, appropriate storage facilities)”. The same conclusion had also been reached in as they looked at food security issues in the region.
Undeniably, Vietnam is not the only country facing this problem of food loss but it is a common problem in the region as well. In Asia, in total 28.7 % of the food is lost and wasted. Of this volume, 31% of the food loss is found during the harvest phase and 34% in the postharvest phase, while 35% is found in the processing, packaging, distribution and consumption .
Even though Asia and the Pacific have an incredible capacity in producing food, 51% of the world’s population residing in this area is still on the edge of food insecurity. Inefficient and inappropriate postharvest management leads to 20%-50% losses along the postharvest value chain in ASEAN. This is equivalent to over 100 million tons of food production lost, or a value of USD 5 billion.
According to FAO, there are many causes of food loss and waste, some of which are “harvesting at an incorrect stage of produce maturity, excessive exposure to rain, drought or extremes of temperature, contamination by micro-organisms and physical damage that reduces the value of the product.
Reduction of food loss and waste is now part of the 2030 Agenda under SDG 12, which seeks to “ensure sustainable consumption and production patterns.” Target 12.3 under this goal is “for halving per capita global food waste at the retail and consumer levels and reducing food losses along the production and supply chains, including post-harvest losses, by 2030”. The FLW reduction goal was also included as one of the five targets in the Zero Hunger Challenge launched by the UN at the Rio+20 Conference in 2012.
The Minister of Vietnam’s Ministry of Agriculture and Rural Development, Mr. Nguyen Xuan Cuong, announced in January 2018 that even though the annual average production of horticulture products (fruits and vegetables) was 22 million tons per year, only 9% of the total products was processed. The rest was either consumed fresh or lost (>25%) due to their perishability.
Among many solutions proposed by experts to reducing postharvest loss of horticultural crops in developing countries including Vietnam, a compelling one is to invest and develop postharvest technology which helps with lengthening the shelf life of the products. Depending on each commodity, it could be a cold storage solution or drying the perishables when the price drops below breakeven point.
According to Dr. Nguyen Van Phong, Head of Postharvest Technology Department, Southern Fruit Research Institute, processed products development under dried forms may be considered more effective as the product can be preserved for a longer period of time and diversified in many types for various use purposes.

Tan Binh Agriculture Cooperative is situated in an isle of Thanh Binh District, Dong Thap Province, Vietnam. The cooperative’s members produce about 2,000 tons of fresh chili (bird’s eye chili) per season (6 months). For the past few years, the impacts of climate change have been as present as ever with the unusually high level of flood and extended period of dry season to the point of severe draught. The heavy rain during this season resulted in the loss of dried chili in the conventional method: on the ground out in the open air. Whenever the rain comes, the chili must be gathered and stored temporarily inside some storage space without being spread out. This exposes the chili to contamination such as insects, diseases, parasites and mould. The final products are deformed and the original color is drastically faded together with vitamins and minerals. The deputy director of the cooperative, Mr. Nguyen Van Son, confirmed that during rainy season, the loss after drying chili is 25% of every batch which is about 1 ton. The loss was reduced to only 10% after using the SDD.
Having conducted tests and measurements with several commodities using the SDD since the middle of 2017, Dr. Phong is optimistic with this drying solution for the Mekong Delta region. Solar greenhouse technology has convincingly proven its advantages in regard of energy consumption and product quality.
In Vietnam, the SDD is being disseminated through closed cooperation between Jun88 and Center for Application of Science and Technology Progress (Agitech), An Giang. Agitech’s engineers have received a complete training course from Dr. Serm Janjai, the inventor of the SDD, at Silpakorn University, from the theory and scientific research results behind the SDD’s design to fabricating and installing demonstrations.
The localization of the SDD’s manufacturing has reduced the cost significantly compared to importing the whole kit from Thailand as before while still ensuring the exact same quality.
