What is Biodiversity and Ecosystem Services?
Historical Background
The concept of biodiversity gained prominence in the 1980s, although the importance of natural resources was recognized much earlier. The term 'biodiversity' itself was popularized by E.O. Wilson.
The 1992 Convention on Biological Diversity (CBD) marked a turning point, establishing a global commitment to conserve biodiversity, sustainably use its components, and fairly share the benefits arising from the utilization of genetic resources. The concept of ecosystem services gained traction in the late 1990s and early 2000s, with the Millennium Ecosystem Assessment (MEA) in 2005 providing a comprehensive evaluation of the state of ecosystems and their services worldwide. This assessment highlighted the link between biodiversity loss and the decline in ecosystem services, emphasizing the need for integrated conservation and sustainable management strategies.
Since then, numerous studies and initiatives have focused on valuing ecosystem services and incorporating them into decision-making processes.
Key Points
12 points- 1.
Biodiversity encompasses genetic diversity, species diversity, and ecosystem diversity. Genetic diversity is the variation within a species. Species diversity is the variety of species in a habitat. Ecosystem diversity is the variety of ecosystems in a region.
- 2.
Ecosystem services are categorized into four main types: provisioning services (e.g., food, water, timber), regulating services (e.g., climate regulation, water purification), supporting services (e.g., nutrient cycling, soil formation), and cultural services (e.g., recreation, aesthetic value).
- 3.
Key stakeholders include governments, local communities, NGOs, researchers, and businesses. Governments are responsible for policy and regulation. Local communities often depend directly on ecosystem services. NGOs advocate for conservation. Researchers provide scientific knowledge. Businesses can impact biodiversity through their operations.
- 4.
Approximately 60% of the world's ecosystems are degraded or being used unsustainably, according to the Millennium Ecosystem Assessment.
- 5.
Biodiversity and ecosystem services are closely linked to climate change. Healthy ecosystems can help mitigate climate change by sequestering carbon, while climate change can exacerbate biodiversity loss and disrupt ecosystem services.
- 6.
The Aichi Biodiversity Targets, adopted in 2010 under the CBD, set global goals for biodiversity conservation. These targets aimed to address the underlying causes of biodiversity loss, reduce direct pressures on biodiversity, and improve the status of biodiversity by safeguarding ecosystems, species, and genetic diversity.
- 7.
Some ecosystems, such as wetlands and mangroves, provide disproportionately high levels of ecosystem services compared to their size.
- 8.
The economic value of ecosystem services is often underestimated, leading to their degradation. Incorporating the value of ecosystem services into economic decision-making can promote more sustainable practices.
- 9.
Biodiversity is not evenly distributed across the globe. Some regions, known as biodiversity hotspots, have exceptionally high concentrations of endemic species and are under significant threat.
- 10.
A common misconception is that biodiversity conservation is only about protecting rare or endangered species. In reality, conserving common species and maintaining healthy ecosystems is equally important for providing ecosystem services.
- 11.
The Environment Protection Act, 1986 in India provides a framework for protecting and improving the environment, including biodiversity. It empowers the government to take measures to prevent environmental pollution and conserve natural resources.
- 12.
The concept of Payment for Ecosystem Services (PES) involves compensating landowners or communities for managing their land in a way that provides ecosystem services. This can incentivize conservation and sustainable land use.

Recent Developments
7 developmentsThe Kunming-Montreal Global Biodiversity Framework, adopted in 2022, sets new global targets for biodiversity conservation, including protecting 30% of the planet by 2030 (the '30x30' target).
There is increasing focus on nature-based solutions (NbS) to address climate change and biodiversity loss. NbS involve using ecosystems to provide benefits for both people and nature.
The Indian government has launched several initiatives to promote biodiversity conservation, including the National Mission for a Green India and the Compensatory Afforestation Fund Management and Planning Authority (CAMPA).
Growing awareness of the economic value of ecosystem services is leading to the development of new financial mechanisms, such as biodiversity credits and impact investing.
Research continues to improve our understanding of the complex interactions between biodiversity, ecosystem services, and human well-being. This includes studies on the impact of pollution, habitat loss, and climate change on ecosystems.
The use of technology, such as remote sensing and artificial intelligence, is enhancing our ability to monitor biodiversity and ecosystem health.
Debates continue regarding the best approaches to biodiversity conservation, including the role of protected areas, community-based conservation, and sustainable resource management.

61. What is biodiversity and what are ecosystem services? How are they linked?
Biodiversity refers to the variety of life on Earth, encompassing genetic, species, and ecosystem diversity. Ecosystem services are the benefits humans derive from ecosystems, categorized as provisioning, regulating, supporting, and cultural services. Biodiversity is crucial for maintaining healthy ecosystems, which in turn provide these essential services. The loss of biodiversity can disrupt ecosystem functions and reduce the provision of these services.
Exam Tip
Remember the four categories of ecosystem services: provisioning, regulating, supporting, and cultural. Think of examples for each to better understand the concept.
2. What are the key provisions related to biodiversity as per the concept?
The key provisions related to biodiversity as per the concept are: * Biodiversity encompasses genetic diversity, species diversity, and ecosystem diversity. * Ecosystem services are categorized into provisioning, regulating, supporting, and cultural services. * Key stakeholders include governments, local communities, NGOs, researchers, and businesses. * Approximately 60% of the world's ecosystems are degraded or used unsustainably. * Biodiversity and ecosystem services are closely linked to climate change.
