Combating desertification and restoring affected lands is a critical priority on the global environmental agenda. With more than 2 billion hectares of degraded land impacting 3 billion people, food security, water access, and biodiversity are at stake.
In the face of these challenges, the United Nations Environment Programme (UNEP) has identified seven effective strategies to recover degraded ecosystems and ensure a sustainable future.
Effective Solutions to Halt Desertification
The current agro-industrial approach consumes the valuable natural resources we need to survive. To ensure a sustainable food supply, it is crucial to transform these practices into systems that collaborate with nature.
It is essential to abandon harmful chemicals and promote environmentally friendly agricultural methods. By protecting soil health, we can reduce global warming and conserve essential moisture.
Regenerative agriculture offers promising solutions, allowing governments and farmers to produce food without compromising ecosystems. Reforming subsidies towards sustainable practices and cultivating climate-resistant varieties are fundamental steps.
Soils are home to approximately 60% of living species and provide 95% of our food. They also act as important carbon sinks, mitigating climate change.
Practices such as organic farming, reduced tillage, and the use of organic compost are crucial to keeping land fertile and preventing soil erosion.
Pollinators, such as bees and butterflies, are vital for agricultural production. However, they are in decline due to pollution and habitat loss, affecting three out of four crops that depend on them.
To reverse this trend, restoring grasslands and planting native flora are essential.
Freshwater ecosystems play a crucial role in maintaining the fertility of lands and mitigating the effects of droughts and floods. However, pollution and overexploitation are accelerating their deterioration.
UNEP recommends restoring wetlands and improving water quality, as well as eliminating invasive species to protect these strategic resources.
The livelihood of more than 3 billion people depends on marine resources. Restoring mangroves, coral reefs, and marshes is vital to protect biodiversity and increase resilience against extreme events.
Additionally, reducing plastic waste and properly managing wastewater are critical steps to preserve these ecosystems.
Cities are responsible for more than 60% of global emissions and consume the majority of natural resources. To minimize their impact, UNEP suggests creating urban forests, vertical gardens, and green spaces to improve air quality.
The UN estimates that an investment of $542 billion annually until 2030 is needed to achieve climate and biodiversity goals. Governments and companies must lead the mobilization of resources towards ecological restoration projects.
Stopping desertification and restoring lands does not depend on a single action but on a comprehensive approach that combines public policies, private investment, and changes in consumption habits. Ecological restoration is key to ensuring food, water, and a stable climate.
