A center of origin (or center of diversity) is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties.[2] They are also considered centers of diversity. Centers of origin were first identified in 1924 by Nikolai Vavilov.

In the context of biodiversity, what do you understand by the term Vavilov center?

View answer

The Himalayan ecosystem is highly vulnerable to damage, both due to geological reasons and on account of the stress caused by increased pressure of population, exploitation of natural resources and other related challenges. These aspects may be exacerbated due to the impact of climate change. It is possible that climate change may adversely impact the Himalayan ecosystem through increased temperature altered precipitation patterns, episodes of drought and biotic influences.This would not only impact the very sustenance of the indigenous communities in uplands but also the life of downstream dwellers across the country and beyond.Therefore, there is an urgent need for giving special attention to sustain the Himalayan ecosystem. This would require conscious efforts for conserving all the representative systems.Further, it needs to be emphasized that the endemics with restricted distribution, and most often with specialized habitat requirements, are among the most vulnerable elements. In this respect the Himalayan biodiversity hotspot, with rich endemic diversity, is vulnerable to climate change.The Threats include possible loss of genetic resources and species, habitats and concomitantly a decrease in ecosystem services. Therefore, conservation of endemic elements in representative ecosystems/habitats assumes a great significance while drawing conservation plans for the region.Towards achieving the above, we will have to shift towards contemporary conservation approaches, which include a paradigm of landscape level interconnectivity between protected area systems. The concept advocates a shift from the species-habitat focus to an inclusive focus on expanding the biogeographic range so that natural adjustments to climate change can proceed without being restrictive.Q.Which one of the following statements best implies the need to shift toward contemporary conservation approach?

Biodiversity is the living fabric of our planet. It underpins human well-being in the present and in the future, and its rapid decline threatens nature and people alike. According to reports released in 2018 by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the main global drivers of biodiversity loss are climate change, invasive species, over-exploitation of natural resources, pollution and urbanization .Biodiversity loss implies the reduction and disappearance of species and genetic diversity and the degradation of ecosystems. It jeopardizes nature‘s vital contributions to humanity, endangering economies, livelihoods, food security, cultural diversity and quality of life, and constitutes a major threat to global peace and security. Biodiversity loss also disproportionally affects the most vulnerable exacerbating inequality .To halt or reverse this decline it is vital to transform people‘s roles, actions and relationships with biodiversity. This transformation has already begun with the commitment of the international community to the 17 Sustainable Development Goals (SDGs) of Agenda 2030. This global and holistic framework highlights the complex interconnections and interdependencies between society, biodiversity and sustainable development. It recognizes that human behaviour, values and choices shape people‘s interactions with biodiversity, all of which have a direct impact on our collective future on the planet. Awareness and appreciation of the diverse values of biodiversity need to be further amplified and mainstreamed within this global framework in order to transform human behaviour in favour of biodiversity conservation and its sustainable use. Many solutions exist for stopping and reversing the decline in biodiversity. UNESCO‘s diverse networks, programmes and partners have observed positive and inspiring seeds of change around the world. UNESCO also accompanies Member States and their people in their efforts to halt biodiversity loss by understanding, appreciating, safeguarding and using biodiversity sustainably. This publication highlights some of UNESCO‘s biodiversity-related actions and solutions, based on the Organization‘s unique mandate and its diverse normative instruments, networks, programmes and partners. These actions have reduced biodiversity loss and improved the lives of many people around the planet. For each thematic challenge, the publication highlights current actions and solutions that have been successfully implemented, as well as suggestions for improvement and innovation.Q.Which of the following statements is incorrect?
