8 nature-based climate solutions that protect our planet
8 nature-based climate solutions that protect our planet
September 5, 2023
Climate change is harming nature—it’s causing disasters like droughts and floods to strike more often and taking a devastating toll on biodiversity. Yet nature itself is critically important in helping us combat and mitigate climate change. As global temperatures are expected to rise by 1.5°C by 2040 and one million species face extinction, it’s becoming urgent to put nature-based climate solutions—actions that protect, conserve, restore, sustainably use, and manage natural or modified ecosystems—into practice for the health of the planet. Such nature-positive solutions are central to IFAW’s strategy to tackle the climate crisis. Here are eight nature-based climate solutions we are pursuing to help protect the planet and the animals and people that inhabit it.
What are nature-based solutions?
Nature-based solutions are ways to combat the climate crisis that utilize natural resources, including animal and plant life.
Our planet's natural landscapes are crucial to mitigating climate change because of their ability to store carbon dioxide and provide clean air, water, fertile soil, and other ecosystem services. When we work to protect these landscapes through conservation initiatives, we enhance their ability to fight climate change. Forests, for example, store tonnes of carbon as plants undergo photosynthesis, keeping it out of our atmosphere. And these forests can't sustain themselves without wild animals—for example, elephants, through their foraging and roaming, encourage the growth of younger plants at the same time as they provide breathing room for older, larger trees.
Protecting natural resources is also key to helping people live more environmentally friendly lives. When nature provides us with plentiful clean water, fresh air, temperature regulation, and food, we don't need to damage the natural world and over-extract its resources. There are ways in which we can exist symbiotically with the natural world to engage in activities like agriculture rather than competing with it for space.
While investing in green energy and more sustainable infrastructure is also important to mitigating climate change, nature-based solutions are crucial and often overlooked.
1. Wildlife conservation
Climate change is closely linked to biodiversity loss. Protecting and restoring biodiverse ecosystems and the wild animals that inhabit them—such as elephants and rhinos—allow these animals to persist and continue to perform key ecosystem services. An example of this is how elephants gather and disperse seeds through their diet and digestion, which allow plants to flourish.
Conserving biodiversity also helps maintain natural resources such as water, shade, and soil, which enables people and nature to coexist sustainably. When nature thrives, people can thrive without depleting natural resources.
2. Marine conservation
Whales, sharks, phytoplankton, coral, and other marine life also play crucial roles in fighting climate change. Whales feed phytoplankton with their faecal waste, and these tiny organisms together capture about 37 billion tonnes of carbon dioxide per year—about 40% of all carbon dioxide produced.
Similarly, sharks scare sea turtles away from underwater seagrass meadows, which prevents them from overgrazing. As seagrasses are an important holder of blue carbon, sharks protect blue carbon stores. Sharks and whales both also store tonnes of carbon in their bodies.
Not only do coral reefs harbour the highest biodiversity of any ecosystem, hosting more than one quarter of all fish species, but they also provide a variety of ecosystem services such as food, protection from flooding, and ecotourism opportunities.
3. Ecosystem reservation
Ecosystem reservation is the setting aside of land to preserve its ecological features. Reservation prevents land from being used for agriculture, roads, housing, or industrial development. Instead, it helps maintain its natural resources for the wildlife that inhabit it. This is crucial to maintaining biodiversity, as these animals not only need food and water to flourish but also room to roam. Ecosystem reservation also allows plants to thrive, which is important for combatting global warming, as all plants capture and store carbon via photosynthesis.
4. Blue carbon projects
The carbon stored in the ocean—called blue carbon—is about 50 times greater than the amount in our atmosphere. Blue carbon is crucial to mitigating climate change by keeping carbon from accumulating in the atmosphere.
Animals and the plants have the potential to capture and store enough carbon dioxide to keep global warming below 1.5°C, and much of this carbon storage happens in the ocean. Whales, the largest animals on the planet, can store up to 33 tonnes of carbon dioxide during their lifetimes, which then gets held at the bottom of the ocean for centuries after their death rather getting released into the atmosphere.
5. Landscape management
Landscape management involves managing critical areas for wildlife that exist within wider, interconnected landscapes, including community lands. Crucial resources like watersheds are being impacted by climate change, and by managing these landscapes effectively—by planting trees, harvesting rainwater and recharging aquifers, agroforestry, holistic rangeland management, permaculture, and regenerative farming—we protect them into the future.
6. Disaster response and wildlife rescue
Disaster response and wildlife rescue focus on saving individual animals to benefit their vulnerable species and protect biodiversity. Many species, such as African savannah elephants and North Atlantic right whales, have such low populations and slow reproductive habits that saving orphaned or injured young is critical to the species’ survival and the role they play in the health of their ecosystem.
7. Supporting wildlife-friendly livelihoods
Supporting wildlife-friendly livelihood opportunities for people who live alongside wildlife is another key way to protect biodiversity, and it’s imperative to nature-based climate solutions. It can be done on a large scale, such as supporting the whale watching industry to provide an alternative source of income to nations that once relied on whaling—or it can happen on a smaller scale, such as investing in education programs for women in Africa to learn trades so they can begin wildlife-friendly careers; this can reduce poaching and threats of human-wildlife conflict in these communities.
8. Combatting wildlife crime and trafficking
Combatting wildlife crime and wildlife trafficking ultimately keeps more wild species in their natural habitats, which in turn keeps these ecosystems healthy. This work involves protecting animals at a policy level and through on-the-ground actions to help to restore biodiversity in areas impacted by wildlife crime.
IFAW champions nature-based climate solutions
At IFAW, we recognise the urgent need to take climate action using a holistic approach that puts nature front and centre. Through climate-smart conservation, we acknowledge that climate change is already impacting animals and their habitats. We and our partners help government authorities and community conservancies understand the risks climate change poses and develop effective conservation management plans that can adapt to climate change in the short and long term.
For example, in East and southern Africa, rainfall patterns are increasingly unpredictable, causing more frequent and severe droughts and floods. IFAW is addressing these threats in various ways. In Hwange National Park in Zimbabwe, we are ensuring that elephants and other animals have access to water during droughts. In Kenya, we are working with community conservation groups around Tsavo National Park to understand how climate change is affecting their landscape and adopt climate-smart conservation management measures.
We also promote integrated landscape management, which broadens climate-smart conservation beyond the boundaries of a particular conservation area. For example, in many protected areas where we work, such as Amboseli in Kenya and Hwange in Zimbabwe, elephants travel between conservation areas in search of food, water, and other resources. This range of movement may expand as the climate changes. IFAW’s Room to Roam initiative aims to increase the long-term resilience of elephant populations by connecting core elephant habitats and creating safe passageways.
Disaster response and animal rescue are key areas of our work that ultimately help the climate through nature protection. We actively rescue animals that have been affected by disasters to help these vulnerable populations remain stable in difficult circumstances. For example, when climate change-related bushfires impact koalas in Australia, IFAW responds by rescuing affected animals. Given the critical role so many animals play in maintaining the health of their ecosystems and mitigating climate change, by increasing survival rates of animals in distress, IFAW is protecting biodiversity and supporting nature’s ability to combat the climate crisis.
Our work to fight wildlife crime and trafficking minimises the effects of poaching and ensuring that animals like elephants can continue to play their critical roles in mitigating climate change through the carbon cycle. This work is done both on the ground and at a policy level. On the global climate policy stage, we also advocate for more finance to be invested into nature-based solutions.
Nature-based solutions don’t just protect wildlife; they also make people and the planet more resilient to the changing climate.
