What are ecosystem services: defining the foundations of life
Ecosystem services encompass the multitude of benefits that natural ecosystems offer to humans and the environment. These services can be categorised into provisioning, regulating, cultural, and supporting services. Each category plays a vital role in maintaining the delicate balance of our planet's ecosystems and supporting human wellbeing.
10 Vital ecosystem services.
Provisioning services
1. Freshwater supply: nurturing life's thirst
Freshwater supply is an essential ecosystem service that nurtures life's thirst and sustains the wellbeing of all species. It plays a vital role in providing clean water for drinking, from water purification to water retention, irrigation, and industrial processes. Freshwater sources, such as rivers, lakes, reservoirs, and underground aquifers, serve as lifelines for human civilisations, supporting daily needs and enabling agricultural productivity. Only 3% of all water on Earth is fresh water, with even less accessible for human use.

Wetlands such as marshes and swamps act as natural filters, removing pollutants and impurities from the water as it flows through. This natural filtering process not only provides us with clean drinking water but also helps to prevent water-borne diseases.
Healthy ecosystems also play a crucial role in retaining freshwater through the natural water cycle. Trees, plants, and other vegetation help regulate water flow, minimising the risk of floods and drought.
Salt marshes and marine ecosystems are also essential components of our freshwater supply. These saltwater environments help to regulate the salinity levels of coastal waters, preventing saltwater intrusion into freshwater sources.
Marine conservation efforts are crucial in maintaining the health of our ecosystems as they are all interconnected. Pollution, overfishing, and climate change are all significant threats to our freshwater supply, and we must take collective action to preserve these vital ecosystem services.

2. Food production: harvesting nature's bounty
Food production, driven by the collaborative efforts of farmers, ranchers, and fishers, enables us to harvest nature's bountiful offerings and sustain our global food supply. Around 80% of the world’s food is produced by family farms (that is, farms of less than 2 hectares in size). Agriculture and fisheries serve as the backbone of food production, ensuring there is enough nourishing sustenance to meet the needs of a growing population. Marine ecosystems play a crucial role in food production, providing a source of protein for billions of people worldwide, with fish representing about 17% of the global meat intake.
According to the World Wildlife Fund (WWF), agriculture is the leading pollution source in many countries. The pesticides, fertilisers, and other toxic chemicals used pollute the soil, water, and air and can remain in the environment for many generations. Moreover, agricultural practices have proven notoriously unsustainable and have contributed to the homogenisation of the world’s ecosystems. However, through sustainable farming practices, like regenerative farming, agroforestry, and crop rotation, agriculture can harness the Earth's power to yield more abundant harvests more sustainably.
Similarly, fisheries are a prominent resource-depleting industry, harvesting vast amounts of fish from our oceans, lakes, and rivers. However, through responsible fish and seafood harvesting and aquaculture, this industry can become more sustainable and continue to provide the world with a vital source of protein.
The adoption of sustainable practices in the agricultural and fisheries industry, along with nature conservation, is thus essential for maintaining healthy ecosystems and promoting sustainable food production. Farmers and fishers who rely on natural resources must be aware of their impact on the environment and take steps to minimise such impact. By adopting more sustainable practices, we can ensure these provisioning services are environmentally friendly and economically viable and can address our basic nutritional requirements, continue to provide for a growing population, and support local economies, livelihoods, and food security on a global scale.
Genetic resources are vital in ensuring that crops and livestock are resilient to environmental stressors and can adapt to changing climate conditions. By preserving genetic diversity, we take steps to ensure that our food systems remain robust in the face of future challenges.

Regulating services
3. Climate regulation: nature's cooling system
One of nature's most vital ecosystem services is climate regulation. This service refers to the natural processes that regulate the climate on Earth. Forests, oceans, and wetlands act as natural climate regulators, absorbing and storing large amounts of carbon dioxide, acting as huge carbon sinks. They play a critical role in maintaining a stable climate for the wellbeing of all species. Forests sequester carbon dioxide through photosynthesis, oceans absorb carbon dioxide through photosynthesis by plant-like organisms (like phytoplankton), and wetlands store significant amounts of carbon in their soils and vegetation.

Carbon dioxide emissions absorb and radiate heat, therefore contributing to changing climates. The carbon sequestration provided by these carbon sinks therefore helps reduce greenhouse gas concentrations and mitigate climate change.
Marine and coastal ecosystems, such as mangroves, salt marshes, and seagrass beds, play a crucial role in regulating the Earth's climate. These ecosystems absorb and store large amounts of carbon dioxide. Moreover, they also help to prevent coastal erosion and protect against storm surges and flooding.
Coral reefs are another important ecosystem that contributes to regulating the Earth's climate. Coral reefs are known as the ‘rainforests of the sea’ due to their high biodiversity. They also help to regulate the Earth's climate by absorbing and storing large amounts of carbon dioxide. However, coral reefs are under threat due to climate change and other human activities such as overfishing, pollution, and coastal development. Therefore, marine conservation efforts are vital to protect and restore these ecosystems.
Moreover, climate regulating services provide intermediate services that are also important to human wellbeing. For example, climate regulation helps to maintain the Earth's temperature, which is essential for agriculture and food security. It also reduces the incidence of natural disasters such as floods, droughts, and hurricanes.
The stable climate these ecosystems maintain is vital for preserving habitats, biodiversity, and the continuity of essential ecosystem services that support human societies. Protecting and restoring these ecosystems is thus crucial for ensuring a healthy planet and the wellbeing of all species.

4. Water regulation: balancing nature
Water regulation is an essential ecosystem service that involves balancing and managing water flow in natural systems. The natural world provides many ways to regulate and balance water, from salt marshes to coral reefs. These natural systems play a vital role in maintaining our planet's water cycle, which is essential for all life forms.
Salt marshes, for example, act as natural sponges that retain floodwaters and prevent coastal erosion. They are also crucial habitats for many species of fish and birds. Coastal ecosystems also provide vital protection against hurricanes and storms, which are becoming more frequent and severe due to climate change.
Coral reefs are another critical ecosystem that helps regulate water. They act as natural filters that remove impurities from seawater, providing clean water for marine life and humans. They also protect coastlines from storms and provide a home for over 25% of all marine life.
Freshwater ecosystems such as watersheds and wetlands are vital in regulating water by acting as natural buffers, purifying water sources, and reducing the risk of floods. Watersheds, with their intricate network of rivers, streams, and underground aquifers, help to capture, store, and distribute water resources. Wetlands act as natural sponges, absorbing excess water during heavy rainfall and slowly releasing it during dry periods, thus maintaining a more balanced water flow.

5. Pest regulation: nature's pest control
Pest regulation is a vital ecosystem service provided by nature, acting as a natural pest control system. Ecosystems and their biodiversity maintain a delicate balance where various species, including predators, parasites, and pathogens, help regulate pest populations. By preying on or controlling pests, these natural enemies play a crucial role in preventing pest outbreaks and minimising the need for chemical interventions. Many species of birds, mammals, and insects, like ladybugs and wasps, play a role in controlling pests, such as mosquitoes, ticks, and agricultural pests like aphids and caterpillars.
The concept of ecosystem services recognises the importance of these interactions and the benefits they provide to humans. For instance, the natural control of pests reduces the need for synthetic pesticides, which negatively impact the environment and human health. Invasive species can also disrupt these interactions and lead to a decline in pest control services.

Forest services, such as maintaining healthy forests and conserving biodiversity, are vital in pest regulation. Forests are home to many species that regulate pest populations. For example, bats feed on insects, and woodpeckers feed on tree-dwelling insect larvae.
Pest regulation is a critical ecosystem service. We need to better understand and value the relationships between ecosystem services, the impact of invasive species, and the importance of forest services. We must also take steps to preserve natural habitats, such as forests and grasslands, and promote biodiversity, which is essential to maintaining robust pest regulation services. By embracing nature's pest control mechanisms, we can foster sustainable agriculture, minimise environmental impacts, and protect the health of ecosystems and human populations.
