The biodiversity in any ecosystem provides various fundamental benefits for our survival such as food, soil production and stabilisation, climate regulation, water purification, bioenergy etc. These benefits and services are very crucial for the survival of man and other organisms on the earth. Valuation of ecosystem is essential to respite human activities apart from accounting their services in the regional planning. Nearly, 75 percent of the genetic diversity of domesticated crop plants has been lost in the past century. Valuation of any ecosystem involves assessment of total economic value (TEV) of the ecosystem considering provisioning, regulating, supporting and bio indicator services provided by them.
The most threatening factor for the sustenance of biodiversity and ecosystems are the environmental factors specifically climatic conditions of the area. The change in the chemical composition of atmosphere and increasing concentrations of greenhouse gases (GHGs) consequent to the developmental paradigm shifts impose significant changes in the biogeochemical cycles, natural biodiversity and ecosystem functions.
The 2030 agenda for global sustainable development is committed to be achieved in a balanced and integrated manner. It is envisioned that development and the application of technology are climate-sensitive, respect biodiversity and are resilient. One of the major goals is to take urgent action to combat climate change and its impacts on biodiversity and ecosystem services. The Nationally Determined Contributions (NDC) targets adopted as per the COP 21 Paris agreement stipulations give large thrust on reduction of emissions and limiting warming to 1.5 to 2°C above pre-industrial levels and building climate resilience through afforestation, biodiversity conservation and adoption of clean/green technologies, prudently monitored and managed so that the ecosystem functions are uninterrupted.
