Combatting meals loss and waste is a key element of the combat in opposition to local weather change. Annually, 1.3 billion tons of meals is wasted or misplaced. Oftentimes, after we consider meals loss or waste, the socio-economic impacts of those phenomena sometimes come to thoughts, together with folks going hungry and economies being much less productive. Nevertheless, meals waste or loss will be very damaging for the surroundings as properly. They will negatively affect the surroundings and exacerbate world warming. It is because when meals is allowed to spoil, it emits methane, a strong greenhouse fuel (GHG), which is launched into the environment.
A number of components contribute to meals waste and loss. These embrace throwing away odd-looking produce and shopping for or cooking extreme quantities of meals. One other key issue is the shortage of correct storage services to stop meals spoilage, notably in much less developed nations the place this infrastructure isn’t as strong.

Due to this fact, by enhancing meals storage methods, we will intention to cut back starvation and restrict components that contribute to local weather change. That is essential for growing nations the place a lot of the meals waste and spoilage will be attributed to a scarcity of acceptable storage services.
The results of meals waste because of poor storage services
Well being Impacts
As meals strikes from farm to desk, it passes by means of numerous levels. Firstly, it’s harvested and shipped to wholesalers. From this level, the produce can both be despatched to grocery shops or to meals processing firms to be prepped, together with to be canned, packaged or frozen. Between these levels, the produce tends to sit down for lengthy intervals.
With out sustaining a cool surroundings to retailer the produce, the meals can start to spoil and even be contaminated with micro organism. Which may trigger food-borne diseases if consumed.
For instance, in Uganda, corn is grown by farmers who typically lack the services to dry and retailer the produce. This results in the produce being contaminated with fungi, which produce aflatoxins. These are dangerous to human and animal well being and might trigger well being issues like liver injury and even most cancers.
International locations that lack satisfactory chilly storage services are sometimes topic to excessive financial losses because of spoiled produce. It is because meals like milk, fruit, greens, seafood and meats all are extremely reliant on chilly chains.
Estimates present that growing nations lose upwards of 23% of perishable merchandise earlier than the meals even reaches markets. As an example, Ethiopia loses one-third of its saved corn inside 5 weeks of harvest on account of acceptable chilly storage services. Equally, India’s Ministry of Meals Processing Industries estimated that the nation misplaced 56 million tons of meals within the yr 2019. This was primarily on account of a scarcity of chilly chains to maintain the meals recent. This extreme loss was estimated to have costed $10 billion! Via satisfactory chilly storage services, these in depth meals and financial losses may have been prevented.
When meals is thrown away, it contributes to nitrogen air pollution in native ecosystems. In aquatic environments, this could trigger algae blooms and useless zones. Moreover, the yearly emissions from meals waste account for 4% of GHG emissions worldwide. The truth is, estimates present that if meals waste had been a rustic, it might be the third-largest emitter on the earth. It will solely fall behind China and the U.S.
Because the human inhabitants is rising, agricultural manufacturing might want to improve by over 70% to satisfy dietary wants. With this improve, there’s more likely to be a concurrent improve in meals waste. If not managed appropriately, this may put additional pressure on the planet.
Sustainable chilly storage in growing nations
In growing nations, one of many essential causes that meals goes to waste is due to the shortage of acceptable chilly storage methods, which stop meals spoilage. Nevertheless, this can not simply be solved by adopting conventional refrigeration methods. It is because this method isn’t sustainable for growing nations in the long run.
At present, most current refrigeration methods launch hydrochlorofluorocarbons (HCFCs) into the environment. These are extraordinarily potent GHGs, that are launched into the environment and contribute to world warming. These chilly storage methods additionally are inclined to depend on fossil gasoline vitality sources, which additionally contribute to local weather change. Due to this fact, adopting solar-powered chilly storage methods can be economically and environmentally helpful for minimizing meals loss/waste.
Sustainable chilly storage methods additionally supply social advantages, particularly for ladies. Most meals loss happens in the course of the harvest and post-harvest levels. In growing nations, these levels are primarily managed by girls. Generally, girls typically have much less entry than males to property and monetary sources. Nevertheless, by supporting girls in less-developed nations with services to handle meals provides, these girls can maximize the merchandise they promote with out worrying about extreme losses because of components out of their management. Via this, they’ll earn extra and consequently enhance the standard of lifetime of their households.
Photo voltaic fridge pilot initiatives
To date, pilots that introduce solar-powered chilly storage methods into growing communities have proven promise. They’ve grow to be a sustainable technique of considerably decreasing meals loss for produce in the course of the harvest and post-harvest levels.
One of many essential areas the place photo voltaic chilly storage has been notably impactful is sub-Saharan Africa. For instance, in Northern Nigeria, a six-month pilot research launched solar-powered chilly storage methods for seven fruit and vegetable markets. This allowed the markets to protect the standard of their meals and even cost greater costs. The truth is, the methods did so properly that they generated $8,000 in web income, permitting them to repay the capital value of the sustainable chilly storage system inside a decade, with out harming the surroundings.
In Uganda, previous to the COVID-19 pandemic, dairy farmers in cooperatives invested in chilly storage methods. This made them extremely resilient to the business disruptions led to by the pandemic, particularly when in comparison with different meals sectors like fish and recent produce.
In communities the place fish is a staple meals, equivalent to northwest Kenya and the Wakatobi islands in Indonesia, photo voltaic fridge pilot initiatives have additionally produced constructive outcomes. These infrastructure methods are environmentally and economically sustainable and permit communities to economize whereas dramatically decreasing meals losses.
The best way ahead…
By adopting solar-powered chilly storage methods, notably in growing nations, we will fight the social, financial and environmental results of meals waste and loss. This in flip can empower neighborhood members, particularly girls from low socio-economic backgrounds, with out harming the surroundings and exacerbating the consequences of local weather change.
