UPSC CSE Prelims 2024

Define the concept of carrying capacity of an ecosystem as relevant to an environment. Explain how understanding this concept is vital while planning for sustainable development of a region.

Carrying capacity is the maximum population size that an ecosystem can sustainably support without degrading itself. When a population exceeds the carrying capacity of its ecosystem, it results in deaths and long-term damages to the ecosystem.

Factors affecting the carrying capacity.

1. Number of resources available in the ecosystem,

2. Size of the population, and

3. Per capita resource consumption

How understanding carrying capacity helps in sustainable development.

1. Economic Planning: Strategies for optimal resource use can be developed through analysis of resource availability and requirements of the economy. Eg. linear economy vs circular economy.

2. Population Control: Based on the carrying capacity of a region. E.g. Gangetic plains can support a higher population but Himalayan region can't. 

3. Biodiversity Conservation: Animal population beyond the carrying capacity of forests leads to man-animal conflicts.

4. Agriculture Management: Agriculture practices must reflect the carrying capacity of the soil type and water availability in the region. E.g., North-west regions in India should adopt less water consuming crops.

5. Urban Planning: Growth of population beyond carrying capacity of urban services may lead to development of slums, pollution, improper waste and sewage disposal, etc.

Suggestions:

1. Inclusion of study on carrying capacity of a region during urban planning.

2. Awareness among people to reduce wastage and for protection of natural forests.

3. Women sensitization and education towards reproductive choices.

As Gandhi once said, "The world has enough for everyone's needs, but not everyone's greed". It is essential for humanity to move on a sustainable development path keeping in mind the carrying capacity of our planet.
