Geography | Biodiversity and Conservation (Fundamental of Physical Geography)

A unique chapter that describes the different ecosytems and the measures to conserve them

Introduction to CBSE Class 11 Social Science Geography Chapter "Biodiversity and Conservation"

“Biodiversity and Conservation” in CBSE Class 11 Geography provides an in-depth understanding of biodiversity, which refers to the variety and variability of life forms within a given ecosystem, region, or on the entire Earth. The chapter discusses different levels of biodiversity, including genetic diversity, species diversity, and ecosystem diversity, highlighting the complex interdependencies among these levels.

The chapter emphasizes the importance of biodiversity in maintaining ecological balance and the benefits it offers, such as ecological services, genetic diversity for crop improvement, and medicinal resources. It also explores the threats to biodiversity, including habitat loss, pollution, overexploitation, and invasive species, which lead to the decline of many species and the degradation of natural habitats.

Conservation efforts, both at national and international levels, are detailed, covering topics like protected areas (national parks, wildlife sanctuaries), biosphere reserves, and global initiatives like the Convention on Biological Diversity (CBD). The chapter concludes by discussing sustainable development and the strategies required to balance human needs with the conservation of biodiversity.
