• Spiritual and Religious Values: Many cultures and religions draw spiritual significance from biodiversity, recognizing certain species, natural sites, and landscapes as sacred or spiritually important.
• Educational Value: Nature serves as an outdoor classroom, offering endless opportunities for learning and discovery. Biodiversity and ecosystems teach us about the complexities of life and our place within the natural world.
• Heritage and Identity: For many communities, local biodiversity is a source of cultural identity and heritage, closely linked to traditional knowledge, customs, and languages that have been passed down through generations.

Through these cultural services, biodiversity not only sustains our physical existence but also enriches our psychological and emotional well-being, connecting us to the earth and to each other in profound ways.

Supporting services form the foundation of all ecosystems, underpinning their ability to provide the other services (provisioning, regulating, and cultural) that we directly benefit from. These fundamental processes include the cycles and systems that sustain life on Earth.

• Nutrient Cycling: Biodiversity plays a critical role in the movement and transformation of nutrients through ecosystems, ensuring the availability of essential elements for plant growth and soil fertility.
• Soil Formation and Maintenance: Organisms contribute to the formation of soil and its maintenance, affecting its structure, fertility, and composition. This process is vital for plant growth and carbon sequestration.
• Photosynthesis: The process by which plants, algae, and some bacteria convert light energy into chemical energy, producing oxygen as a byproduct, is fundamental for life on Earth. It is the basis for most of the energy supply within ecosystems.
• Water Cycling: Biodiversity influences the global water cycle, including precipitation and evaporation processes, playing a significant role in water availability across different ecosystems.
• Primary Production: This is the production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the process of photosynthesis. It forms the base of the food web, supporting all other life forms.

These supporting services are essential for the maintenance of life on Earth, illustrating the deep interconnections between biodiversity and the functioning of ecosystems. By preserving biodiversity, we ensure the resilience and continued provision of all ecosystem services.

Biodiversity plays a crucial role in agriculture by supporting numerous functions that are essential for food production and ecosystem health. This diversity among and within plant and animal species contributes significantly to the sustainability and resilience of agricultural systems.

• Pest and Disease Control: A diverse ecosystem promotes natural control mechanisms for pests and diseases, reducing the need for chemical pesticides. Diverse landscapes support a variety of predators and competitors that help manage pest populations.
• Soil Health: Biodiversity contributes to soil structure and fertility. Different organisms play specific roles in nutrient cycling, organic matter decomposition, and soil aeration, which are vital for crop growth.
• Pollination Services: Many crops depend on pollinators such as bees, birds, and bats for fruit and seed production. Biodiversity ensures the availability of these critical pollination services, directly influencing crop yields and quality.
• Genetic Diversity: The genetic diversity within crop species is crucial for breeding programs, enabling the development of new varieties with improved yield, nutritional quality, and resistance to pests, diseases, and environmental stresses.
• Agroecosystem Resilience: Diverse agricultural systems are more resilient to adverse conditions such as drought, flooding, and climate change. Biodiversity can buffer against environmental fluctuations, ensuring more stable food production.

Enhancing biodiversity in agricultural landscapes is therefore a key strategy for sustainable agriculture, contributing to food security, environmental conservation, and resilience to changing climates.
