Explanation:

• The People’s Biodiversity Register (PBR) entails complete documentation of biodiversity such as flora, fauna medicinal sources, land use and human activities etc. within a particular place such as a city. A PBR comprehensively documents traditional knowledge of local biological resources. 
• Kolkata became the first major metropolitan city in India to prepare a PBR. Chandigarh and Indore are other important cities that have prepared the document.
