Economic impact of waste from food, water, and agriculture in Nigeria: challenges, implications, and applications—a review

202424 citationsOpen accessFederal University of Agriculture

In plain language

Rapid population growth in Nigeria has created intense demand for agricultural produce, food, and clean water, driving a substantial rise in waste generation. Nigeria now ranks among the leading global producers of waste from these sectors. However, existing management systems remain inadequate, leading to severe environmental pollution, elevated carbon dioxide emissions, and public health risks through disease. Because eliminating such waste entirely is unfeasible, sustainable and cost-effective management solutions are essential. These solutions encompass systematic collection, treatment, conversion, recycling, and reuse. By establishing structured approaches to convert and repurpose agricultural, water, and food waste, the country can protect ecosystems, alleviate disease burdens, and unlock substantial economic opportunities from materials that are currently discarded.

Key takeaways

  • Rapid population growth has made Nigeria one of the world's largest generators of food, water, and agricultural waste.
  • Inadequate waste management in Nigeria results in heightened environmental pollution, increased carbon dioxide emissions, and public health risks.
  • Completely eliminating waste generation from food, water, and agriculture is impossible, making effective post-generation handling essential.
  • Adopting eco-friendly collection, conversion, treatment, recycling, and reuse practices can capture significant economic value from discarded materials.

Why it matters

Unmanaged waste from everyday food, water, and farming practices threatens community health, drives up carbon emissions, and damages surrounding ecosystems. Developing affordable ways to collect, treat, and recycle these materials helps prevent pollution and illness. Furthermore, turning waste streams into usable products offers a viable path to generate economic value from resources that would otherwise pollute local environments.

Commercialisation angle

The review highlights potential commercial applications in the collection, treatment, recycling, and conversion of food, water, and agricultural waste into valuable products. Target adopters would include waste-management operators, municipalities, and agricultural processors seeking revenue from by-products. However, because the text is a broad review of systemic challenges and general sustainable practices, it reflects an early conceptual stage without specifying proprietary technologies or near-market readiness.

Abstract

Abstract The surge in Nigeria's population has led to heightened demands for food, clean water, and agricultural products, resulting in a significant increase in waste generation. Nigeria ranks among the top countries globally in terms of waste production, particularly from food, water, and agriculture. Unfortunately, the management of these vast quantities of waste is often inadequate, leading to environmental pollution, disease, and heightened CO 2 emissions. While reducing such waste is important, completely stopping waste generation from food, water, and agriculture is impossible. Therefore, it becomes imperative to adopt eco-friendly and cost-effective approaches to handling this waste, including collection, conversion, treatment, recycling, and reuse. Effectively managing waste can mitigate pollution and its adverse impacts on public health. This review delves into the environmental, economic, and health challenges associated with the generation of waste from food, water, and agriculture in Nigeria. It highlights the importance of implementing sustainable practices for waste treatment, conversion, reuse, and application. By harnessing these waste materials effectively, Nigeria stands to reap significant economic benefits while simultaneously safeguarding the environment from pollution.
