Promoting Sustainable Agriculture and Food Waste Reduction for a Greener Tomorrow

As a crucial factor in the complex web of global sustainability, Sustainable Development Goal 12.3 significantly impacts our unwavering quest for a sustainable future. Its main goal is to cut food waste by half by 2030, dramatically changing our food systems and promoting sustainable consumption and production habits [6]. Conceptually, food waste embodies surplus food initially intended for human consumption that remains unused, concealing a seemingly innocuous disposition that conceals profound societal and environmental ramifications. Nevertheless, there are answers within our reach, resulting from a variety of techniques, from a thorough overhaul of supply chains to practices at the household level like good composting and intelligent meal planning. These measures curtail the harmful impacts of food waste [3].

From food waste to the broader context of sustainability, sustainable agriculture strives to ensure profitability, environmental well-being, and social and economic equity and fulfill present and future generations’ needs within farming practices [8]. Economic viability, ecological preservation, and social and economic equality must all be balanced for agriculture to be sustainable. The following guiding ideas include the core tenets of sustainable agriculture, including raising food system production, generating employment, and providing value [9]. In addition to the principles above, emphasis must also be placed on protecting and enhancing natural resources such as soil, water, and biodiversity [3]. Additionally, sustainable agriculture aims to improve farmer living standards, promote equitable economic development, and increase the resilience of people, communities, and ecosystems to shocks and stresses. Therefore, a vital element of this overarching vision is reducing food waste through sustainable practices, which ties together our dedication to environmental and social well-being worldwide [10].

Understanding Food Waste

Every stage of the food supply chain, from production to consumption, is impacted by food loss. Thus, it creates substantial barriers to sustainable agriculture and harms the environment and society. The United Nations Environment Programme (UNEP) estimates that 1.3 billion tons of consumable food and 1.6 billion tons of primary products are wasted annually, costing the world economy approximately $940 billion and contributing up to 10% of greenhouse gas emissions [6]. Therefore, about 24% of the calories created never go to their intended use.

Food waste has severe environmental impacts, squandering water, land, energy, and labour resources. It emits greenhouse gases, mainly methane, ranking as the third-largest global contributor to emissions. Addressing food waste requires coordinated efforts from governments, corporations, and individual consumers. Strategies such as reducing post-harvest losses through better techniques and infrastructure, enacting legislation to incentivize waste reduction, raising consumer awareness, promoting behavioral changes like meal planning and proper storage, and donating surplus food to food security organizations are essential. Collectively, these approaches work towards reducing and eliminating food waste and safeguarding the environment [7].

Sustainable Agriculture: A Solution

Addressing the global food waste problem will also minimise the excessive amounts of edible resources we pour down the drain and help create a sustainable or moral food system. Food waste not only loses valuable resources but also incites hunger and food insecurity and depletes the planet’s limited resources. Indeed, with so many dire challenges facing us today, sustainable agriculture provides an optimistic answer – a holistic approach to food production that is socially responsible, environmentally friendly and maintains the well-being of future generations by ensuring adequate supplies [11].

Addressing these problems demands that we look for solutions under sustainable agriculture principles, including economic profitability, environment conservation, and equitable society-economic coexistence. The solution to this issue lies in adopting sustainable agriculture practices such as profitability, environmental consideration, and social and economic fairness. This adds significantly to eliminating waste by making sure that agriculture feeds the needs of modern man without causing harm to our environment [2]. Sustainable agriculture is not just a matter of need; it encompasses an ethical and ecological imperative on an equal footing. It has the beneficial effect of reducing our environmental footprint, combating climate change, conserving pivotal water and land resources, and protecting the planet‘s biodiversity [1]. Moreover, it enhances nutrition, improves food safety and quality, and supports global food security. This aligns closely with the broader aspiration outlined through the UN Sustainable Development Goals (SDGs) that target a world free of hunger, with food security, good nourishment, and promoting sustainable consumption and production by 2030 [2].

Sustainable agriculture helps combat climate change by reducing greenhouse gas emissions from farming practices. It relies on natural fertilisers to nurture soil health, prevent erosion, and reduce pollution, balancing productivity and environmental preservation. Techniques like crop rotation, cover cropping, and reduced-till farming enhance soil health and optimise crop production, thus minimising the likelihood of food going to waste. Moreover, by preserving biodiversity and promoting responsible land management, as seen in the Landcare System in Barangay Ned, Philippines, sustainable agriculture protects valuable resources. It supports local food security, diminishing food waste throughout the supply chain [2,4].

Sustainable Agriculture Practices

With the increasing demand for food at a global level, sustainable agriculture becomes critical in responding to the same as far as food is concerned, including issues linked to economics, traditions/culture, and environmental effects. This situation makes it imperative for sustainable and environmentally friendly farming practices that support some basic strategic options [5]. First, careful crop planning is a critical imperative. There is a need for farmers to think twice before they determine the amount of crop output that will be done, hence reducing cases where there will be surplus food, which eventually might go wasted. In light of this, the practical solution is aligned by matching the rates of planting to the actual current demand forces and market trends, thereby reducing extra harvests [5].

Additionally, preaching on crop diversification is very critical. A diverse range of crops in any agricultural activity is vital in cushioning themselves from the adverse effects of crop disasters; moreover, it goes a long way. Thus, this diversity boosts resilience in agricultural systems that can accommodate diverse external conditions, also essential is the deliberate utilisation of limited resources [12]. Wise applications of water and fertilizers as resources should be made by farmers in this regard. Such measures involve the use of water-saving irrigation systems & emphasis on natural fertilizer, both promoting soils’ integrity & mitigating environmental consequences attendant in farming practices [13].

Another critical aspect of sustainable agriculture is the incorporation of composting techniques into it. This leads to appropriate management of organic waste within the farm. This process adds value to the soil and reduces the need for chemical fertilizer, which channels the waste away from landfills toward resource recovery. Reduction in the use of Pesticides and Herbicides is also essential. Integrated pest management (IPM) strategies emerge as a preferred approach, safeguarding beneficial insects, diminishing chemical runoff, and establishing a healthier ecosystem [4].

Collaboration at the local level also warrants earnest consideration. Forging partnerships with neighboring farms, community gardens, or composting programs facilitates collective organic waste management and the judicious sharing of resources. This collaborative endeavor not only serves to fortify the local agricultural community but also yields tangible reductions in waste. Finally, surplus redistribution emerges as a responsible and conscientious practice. Rather than discarding excess produce, it is judicious to contemplate donating it to local food banks, shelters, or charitable organisations. In addition to curbing food waste, this approach extends assistance to those in need and serves as a meaningful intervention against food insecurity within the community. Through the diligent implementation of these sustainable agriculture practices, individuals operating within the agricultural sector can play an instrumental role in promoting responsible food production, minimising their environmental footprint, and cultivating a more robust and equitable food system. These endeavors not only confer benefits upon individual farms but also contribute substantively to the overarching objective of sustainable agriculture, ultimately ensuring the long-term well-being of our planet and the communities it sustains.

Conclusion

Reducing food waste and promoting sustainable farming are essential because they have significant impacts. It highlights how responsible family behavior and comprehensive actions throughout the whole food supply are crucial.

Sustainable agriculture plays an important role here, as it aims to mitigate the adverse environmental influence of agriculture, ensure the preservation of biodiversity, and advocate for responsible control of land and resources. Two concepts connected include reducing food waste and supporting sustainable agriculture, which assist the world in achieving Sustainable Development Goals. They contribute to creating a sustainable future by addressing problems in food production and consumption while keeping the earth’s viability at heart.

Simply put avoidance of food waste and encouragement of eco-friendly farming practices should be deemed ethical as well, with the importance of a healthier, fairer, and environmentally sound world, now and in the future. It is only collaboration that will help people make sensible decisions, leading to the transformation of society, including government departments and corporate organizations.
