The functions of an ecosystem

 

The functions of an ecosystem refer to the natural processes and interactions that sustain life, regulate the environment, and support biodiversity. These functions are essential for the health of the planet and human well-being. The main functions of an ecosystem can be grouped into four broad categories:

---

1. Regulating Functions

These maintain environmental conditions within certain limits:

• Climate regulation (e.g., forests sequester carbon, influencing global temperatures)

• Water purification (e.g., wetlands filter pollutants from water)

• Pollination (e.g., insects pollinate crops and wild plants)

• Disease control (e.g., predators control populations of disease-carrying species)

---

2. Supporting Functions

These are necessary for the production of all other ecosystem services:

• Nutrient cycling (e.g., decomposition of organic matter returns nutrients to the soil)

• Soil formation and maintenance (e.g., organisms break down rock and organic material into fertile soil)

• Primary production (e.g., plants converting sunlight into energy via photosynthesis)

---

3. Provisioning Functions

These provide humans with essential materials:

• Food production (e.g., crops, livestock, fish)

• Freshwater supply

• Raw materials (e.g., timber, fiber, fuel)

• Medicinal resources (e.g., plants used for pharmaceuticals)

---

4. Cultural Functions

These offer non-material benefits:

• Recreational and tourism opportunities (e.g., national parks)

• Spiritual and religious value

• Educational and scientific value

• Aesthetic appreciation

Key Ecological Concepts in IKS

1. Nature as Sacred

• Prakriti (Nature) is considered divine.

• Elements like earth (Bhumi), water (Jala), fire (Agni), air (Vayu), and space (Akasha) are seen as sacred and worshipped as Panchamahabhutas (five great elements).

• Trees like the Peepal, rivers like the Ganga, and mountains like the Himalayas are revered, which fosters protection and respect for nature.

2. Concept of Dharma and Balance

• Ecological balance is part of Dharma (duty/righteousness).

• Humans are not above nature but a part of the interdependent web of life (Lokasamgraha).

• Traditional practices emphasize minimal consumption and sustainable living.

3. Traditional Agricultural Practices

• Use of organic farming, crop rotation, rainwater harvesting, and natural pest control.

• Knowledge of lunar cycles and seasonal rhythms guides planting and harvesting.

• Examples: Vrikshayurveda (ancient science of plant life), use of cow dung and urine in farming.

4. Sacred Groves and Biodiversity Conservation

• Sacred groves (called Devrai in Maharashtra or Sarpakavu in Kerala) are patches of forest preserved due to religious beliefs.

• These groves act as biodiversity hotspots and help maintain ecological balance.

5. Water Management Systems

• Ancient India had advanced water harvesting and management systems like stepwells (baolis), tanks, and canals.

• Example: Johads in Rajasthan, Kunds in Gujarat.

6. Ayurveda and Ecological Ethics

• Ayurveda uses natural herbs and supports ecosystem health.

• It promotes the ethical use of plants, understanding their role in the larger environment.
