Restoring land and water health with nature-based techniques

Bioremediation uses living organisms—like fungi, bacteria, and plants—to clean up contaminated soil and water. It’s low-cost, low-tech, and rooted in nature, making it a powerful alternative to expensive, extractive clean-up methods. From restoring mining sites to detoxifying waterways, bioremediation can regenerate land while supporting community-led recovery. It’s especially valuable in regions where industrial pollution has left deep scars—and where conventional solutions are either too costly or cause more harm than good.

  • Bioremediation is a nature-based technology that leverages microorganisms, fungi, and plants to degrade, absorb, or neutralise contaminants in soil and water. This method provides a low-cost, ecologically sustainable alternative to conventional chemical and physical remediation techniques, which involve manipulating the environment to address the harmful pollutants.

    Bioremediation is used to address pollution from heavy metals, hydrocarbons, pesticides, industrial waste, and persistent organic pollutants, offering both on-site (in situ) and off-site (ex situ) applications. Key approaches include:

    • Bioaugmentation – introducing specialised microbial strains to accelerate pollutant breakdown.

    • Biostimulation – enhancing native microbial activity through nutrient or oxygen supplementation.

    • Mycoremediation – using fungi to decompose hydrocarbons, heavy metals, and toxic chemicals.

    • Phytoremediation – employing plants to absorb, stabilise, or transform contaminants for soil regeneration.

    Bioremediation is particularly vital in the Global South, where extractive industries, mining, and industrial pollution have severely impacted communities. Unlike conventional remediation, this approach not only restores degraded ecosystems but also enhances soil fertility, and improves water quality.

    • Restoring Polluted Waterways: Certain bacteria and algae can break down hydrocarbons, heavy metals, and chemical contaminants in lakes, rivers, and groundwater.

    • Soil Regeneration: Plants and fungi help absorb or degrade toxins, allowing degraded land to become productive again.

    • Community-Led Remediation: Decentralised bioremediation projects empower indigenous and rural communities to restore their lands without dependence on external corporations.

    • Post-Mining Land Recovery: Bioremediation offers an alternative to conventional reclamation efforts, restoring biodiversity in former mining zones.

    • Low-Cost & Scalable Solutions: Unlike expensive industrial decontamination methods, bioremediation can be implemented using locally available materials and knowledge.

  • Despite its low-cost, nature-based approach, bioremediation remains overlooked in favour of chemical and industrial decontamination methods. Large-scale environmental clean-ups often prioritise quick-fix, high-cost solutions that reinforce technological dependency. However, many communities in the Global South are leading locally adapted, decentralised bioremediation efforts, demonstrating that regenerative practices can be more effective, equitable, and culturally relevant.

    The barriers to adoption include a lack of policy support, corporate lobbying for extractive clean-up methods, and limited funding for community-driven initiatives. Additionally, bioremediation is often dismissed due to its longer timescales, despite its potential to restore ecosystems holistically without causing additional damage.

    • Nature-Based, Regenerative Approach: Works with ecosystems rather than against them, allowing long-term, self-sustaining recovery.

    • Cost-effective alternative: Compared to chemical or mechanical remediation, bioremediation is significantly more affordable and scalable in low-resource settings.

    • Community-led approaches: Can be implemented using locally available resources and traditional ecological knowledge, enabling local ownership.

    • Decolonising Environmental Restoration: Challenges the dominance of corporate-led "clean-up" industries that reinforce technological dependency in the Global South.

    • Native Microbial Consortia: Research has shown that native microbial strains can efficiently degrade petroleum hydrocarbons and toxic metals​.

    • Heavy Metal Detoxification: Some plants (like Sunflowers) and microbes have demonstrated high removal rates for lead, mercury, cadmium, arsenic, and other toxic metals.

    • Oil Spill Cleanup: Microorganisms can break down petroleum contaminants in coastal and wetland areas.

    • AI & IoT Integration: The use of biosensors and AI-driven models enables real-time monitoring, enhancing effectiveness.

    • Nanotechnology & Synthetic Biology: Enhances microbial efficiency in complex contamination scenarios

    • Longer Remediation Time: Bioremediation is slower than chemical treatments, requiring months or years for full site restoration.

    • Knowledge & Skill Requirements: Effective implementation requires a combination of scientific understanding and local ecological knowledge.

    • Bioaccumulation Risks in Plants: Some phytoremediation plants can accumulate toxins, requiring safe disposal to prevent secondary contamination​.

    • Biosecurity Risks: Some engineered microbes or invasive plant species may disrupt local ecosystems.

    • Variable Efficiency: Success depends on site-specific conditions, such as soil type, contaminant concentration, microbial activity, and environmental conditions (pH, temperature, nutrient availability)​.

    • Scalability challenges: Large-scale bioremediation projects require long-term monitoring and regulatory approval​.

    • Public Perception: Reasonable resistance to using genetically engineered microbes in the environment​

    • Open-Source and Citizen Science Models: Expanding accessibility to microbial libraries and soil testing methodologies while engaging communities in data collection enhances project sustainability.

    • Native Microbial & Fungal Strains: Leveraging locally adapted species improves success rates and sustainability​.

    • Integration with Agroecology & Permaculture: Bioremediation aligns with sustainable farming and ecosocial transition projects.

    • Multi-disciplinary approach: The understanding of the dynamics of bioremediation requires a multi-disciplinary tactic comprising the biology, biochemistry, and engineering of remediating systems.

    • Decentralised Water & Soil Monitoring: Affordable biosensors and community-led sampling programs can support real-time monitoring of bioremediation effectiveness.

    • Policy & Legal Recognition of Nature-Based Solutions: Growing global recognition of rights-of-nature frameworks supports the adoption of ecosystem-centred remediation.

    • Lack of Awareness and Technical Training: Many communities are unfamiliar with bioremediation.

    • Limited Access to Scientific Resources: Many local initiatives struggle to access lab testing, microbial cultures, or technical training needed for optimal implementation.

    • Funding Gaps for Long-Term Projects: Bioremediation requires ongoing monitoring and investment beyond initial deployment.

    • Challenges in Scaling Up: While effective at small scales, scaling bioremediation across large polluted landscapes is complex.

    • Political and Institutional Resistance: Some governments and industries favour faster but more expensive chemical remediation, and bioremediation projects often face uncertain legal frameworks and long approval times.

    • Corporate Resistance & Greenwashing: Polluting industries often promote superficial clean-up efforts to avoid deeper systemic accountability.

    • Slow Adoption by Development Agencies: Large-scale aid organisations often overlook community-driven, nature-based approaches in favour of high-tech solutions.

Curious examples: what’s already happening?

Case Study no. 1

Grassroots Bioremediation: Community-Led Solutions for Toxic Land Restoration - Pilot

  • Across the Global South, industrial pollution, extractive activities, and chemical contamination have left vast areas of land unusable and hazardous for communities, often without meaningful intervention from the industries responsible. Traditional clean-up methods, promoted by corporations and governments, are costly, extractive, and frequently ineffective, often displacing communities rather than restoring their environments. Grassroots bioremediation is emerging as a powerful alternative, enabling local people to heal their lands using nature-based solutions.

  • The Earth Repair movement, led by community scientists, environmental activists, and indigenous knowledge holders, promotes bioremediation techniques that empower people to reclaim and regenerate toxic landscapes. By leveraging microbial remediation, phytoremediation, and mycoremediation, these projects provide accessible, low-cost, and ecologically sound alternatives to conventional industrial clean-ups.

    ✔️ Microbial remediation uses bacteria to break down chemical contaminants, including petroleum hydrocarbons and industrial waste.

    ✔️ Phytoremediation employs plants to absorb or transform toxins, restoring soil health and improving water filtration.

    ✔️ Mycoremediation harnesses fungi to decompose pollutants, particularly in oil spills, heavy metal contamination, and industrial runoff.

    ✔️ Decolonial environmental justice frameworks ensure that bioremediation efforts are community-driven, resisting corporate-led "clean-up" operations that reinforce extractive dependencies.

    ✔️ Low-tech, local solutions prioritise the use of indigenous plants, fungi, and microbes, rather than imported or synthetic materials.

    • Restores degraded land without displacing communities, allowing for the continued use of traditional agricultural and cultural practices.

    • Strengthens local environmental autonomy, ensuring that affected populations lead the clean-up of their territories.

    • Challenges corporate impunity by offering alternative remediation models that do not rely on extractive industries.

    • Builds ecological and social resilience, demonstrating that communities can rehabilitate landscapes without waiting for external intervention.

    • Creates regenerative economic opportunities, such as mycoculture, agroforestry, and medicinal plant cultivation, integrated into bioremediation efforts.

    • Inspires global movements, positioning bioremediation as a tool of environmental justice rather than just an industry-driven process.

Case Study no. 2

Restoring Agricultural Lands in Central Asia: Bioremediation for Pesticide-Contaminated Soils - Pilot

  • Decades of pesticide overuse and mismanagement have left large portions of agricultural land across Central Asia and Türkiye heavily contaminated. During the Soviet era, the mandatory application of pesticides, including now-banned chemicals, resulted in toxic landfills and widespread soil degradation, affecting both rural communities and food production systems. Today, obsolete pesticide stockpiles and persistent pollutants continue to pose serious environmental and health risks, contaminating water sources, reducing soil fertility, and disrupting ecosystems. Conventional soil clean-up methods, such as excavation and incineration, are expensive, destructive, and inaccessible for many affected communities.

  • As part of a three-year initiative led by the Food and Agriculture Organization (FAO) and the Global Environment Facility (GEF), bioremediation and phytoremediation trials are being conducted in Kazakhstan and Kyrgyzstan to test nature-based solutions for restoring pesticide-contaminated soils. These approaches offer low-cost, environmentally friendly alternatives to conventional soil remediation methods.

    ✔️ Bioremediation harnesses microorganisms to break down or transform pesticide residues, reducing their toxicity and environmental persistence.

    ✔️ Phytoremediation employs hyperaccumulator plants to absorb and immobilise pollutants, preventing further contamination of water sources and food crops.

    ✔️ Localised field trials ensure that remediation strategies are adapted to specific soil types, climate conditions, and agricultural practices in the region.

    ✔️ Digital technologies and remote sensing support the monitoring and scaling of remediation efforts, providing valuable data on soil health improvements.

    ✔️ Policy and governance strategies are being developed to integrate soil remediation into national agricultural frameworks, ensuring long-term sustainability.

    • Restores agricultural land by removing pesticide residues, making soil safe for food production and ecological regeneration.

    • Prevents water contamination by reducing chemical runoff into rivers, lakes, and groundwater sources.

    • Improves food security by ensuring that local farmers can cultivate crops without exposure to harmful pesticides.

    • Reduces health risks by lowering pesticide exposure for farmers, rural communities, and consumers.

    • Promotes cost-effective solutions by using nature-based processes rather than expensive and destructive industrial clean-up methods.

    • Encourages regional collaboration by sharing successful remediation techniques across Azerbaijan, Kazakhstan, Kyrgyzstan, Tajikistan, and Türkiye.

Future scenarios: what might happen in 2035?

As part of our exploration of these nine underhyped technologies, our partners at Pluriversa conducted a foresight exercise to consider possible futures and anticipate the challenges and opportunities within each technology. The exercise produced four scenarios for the year 2035, which you can read here, along with speculative use cases - with different potential outcomes - for each technology. Read on to explore potential future scenarios involving bioremediation.

2035: Rewilding Former Mining Sites

Thanks to the power of bioengineering, biologists can develop super-efficient microorganisms that recover the soil of large areas that used to be exploited for minerals and other resources located below the ground. With the aid of artificial intelligence, new microorganisms can be enhanced in record time.

Previously contaminated sites had been declared a lost cause, and against all expectations, the engineered microorganisms have been able to, in some cases just a couple of weeks, do the unimaginable. They are helping forestry squads plant trees in numbers that would have seemed crazy just some years ago.

Other mining areas, given their large craters, are being transformed into artificial lakes that can provide drinking water.

2035: Trojan Vector of Epidemics

Given their noble cause, nobody thought that bioremediation microorganisms would end up being used to spread diseases on purpose. Yet, this is what is happening as part of a war between countries with advanced bioengineering labs.

Owned by a few corporations, these microorganisms serve as weapons disguised as agricultural products. They can completely destroy entire environments. This has been thoroughly documented in certain parts of the world and environmentalists are concerned at the speed at which they operate.

It is very hard to prevent this, as the technology is too advanced to control and there does not seem to be a way to counter the microorganisms.

Final thoughts

If you’re working on land restoration, environmental justice, agriculture, or water access, bioremediation could offer a grounded, community-driven path forward. The key is treating ecosystems as partners in recovery—not problems to be fixed.

Some ideas to explore next:

  •  Could native plants or fungi support regeneration of polluted farmland or rivers?

  • Might citizen science tools help track soil and water health over time?

  •  Are there local knowledge holders already practising these methods in your region?

  •  Could bioremediation support land justice in post-extractive or post-industrial areas?

This isn’t a quick fix—but it may be a lasting one.
