    Natural and Hermetic Solutions

    The US Food & Agriculture Organization suggests that 13.8% of food is lost between the farm and retailers globally. Other sources cite estimates of 20%, even 40%, especially when discussing farming in developing nations. Post-harvest losses harm farmers economically, as well as the retailers who rely on them, while also wasting much-needed food.

    How can this be prevented?

    1. Pesticides/Fungicides: Pesticides are the go-to solution for stopping pests and other invaders. However, chemical pesticides are expensive and can cause significant environmental damage if overused. In some cases, they may even harm seed viability, challenging the farm in the long run. Natural pesticides do exist as well. For example, the essential oil of wormseed was found to effectively kill fungus in stored wheat. While preferable to synthetic pesticides, the challenge is in finding natural alternatives for each specific combination of crop and infestation.

    2. Hermetic Storage: Possibly the most overall effective solution seemed to be the introduction of airtight, hermetically-sealed storage solutions. These successfully prevented pests and microbial life from infiltrating stored grains, while also slowing down the effects of time and oxidation. A combination of sealed storage, as well as sealed bags for deliveries, were capable of greatly reducing overall losses. For many farms that can afford the investment, this may be the best "one-shot" solution to reducing post-harvest loss.

    3. Other Options

    - Cold storage: Refrigerated storage units slow down spoilage and preserve harvested crops for longer. The FAO estimates that over 500 million tons of food are lost each year to simple spoilage.

    - Aggregation centers: The use of centralized services for storing crops from many producers can allow smaller farms to see the benefits of hermetic or cold storage, with much smaller costs. - On-site packaging: Rather than sending crops uncovered to be packaged, opening them up to damage and loss, packaging them on-site at the farm can improve overall successful shipping rates.

    - Improved food monitoring/tracking: Modern smart systems can be used to track the movement of food from farm to distributor to shelf, helping to narrow down sources of loss along the way.

    In short, post-harvest losses are a global problem across the agriculture industry. Improved education, along with the adoption of better storage and shipping methods backed by scientific data, can do a lot to reduce the problem.

    Climate-Controlled Transportation

    Agricultural scientists work on improving transportation methods to ensure that fruits, vegetables, and other perishable items are kept in ideal conditions while they are being moved from farms to markets. This involves using vehicles that can regulate temperature and humidity, which can dramatically extend the freshness of agricultural products. By maintaining a controlled environment, food degradation is minimized, preventing a significant amount of waste.

    This technique also helps to retain the nutritional value of the food items during transit. Learn about how climate-controlled transportation can enhance food preservation in your community.

    Genetically Modified Crops

    To address the issue of post-harvest losses, one of the strategies adopted by agricultural scientists is the development of genetically modified crops that can stay fresh for longer periods. These crops are altered at the genetic level to enhance their resistance to spoilage and extend their shelf life. This not only reduces waste due to spoilage but also allows food items to travel longer distances, reaching more people.

    This innovation in crop genetics ensures that farmers can potentially get more value from their harvest. Explore the benefits of genetically modified crops for a more sustainable future in agriculture.

    Blockchain for Supply Chain Efficiency

    In the world of agriculture, transparency and efficiency in the supply chain are key to reducing losses after harvest. Utilizing blockchain technology, scientists can create a secure and unalterable ledger of goods from the point of harvest to the consumer. This leads to a reduction in delays, decreases in mismanagement, and an overall improvement in the tracking of goods.

    The end result is a more streamlined process where each stakeholder knows exactly where the product is and its condition. Join the movement for more efficient supply chains by learning about the application of blockchain in agriculture.

    Training in Advanced Harvesting

    To reduce post-harvest losses, agricultural scientists also focus on enhancing the skills of the farmers through training in advanced harvesting techniques. By learning the best times to harvest and the most effective methods of gathering and handling crops, farmers can ensure that the quality of their produce is preserved from the field to the market.

    These practices help in minimizing damage and spoilage, ultimately leading to a more profitable and sustainable farming practice. Support local farmers by encouraging the adoption of advanced harvesting techniques and education.

    Precision Agriculture Technologies

    Precision agriculture technologies encompass a suite of tools designed to optimize field-level management regarding crop farming. By utilizing data, sensors, and information technology, these tools enable farmers to assess their crop needs and apply the exact amount of water, fertilizers, or pesticides required, thereby minimizing waste and enhancing crop yields.

    Such technologies can significantly contribute to reducing post-harvest losses by ensuring that crops are of high quality and less susceptible to disease or spoilage. Join the initiative to implement precision agriculture technologies for a more efficient and responsible farming future.
