Read moreīiodiversity in freshwater ecosystems is under grave threat from human activities, due to the combined effects of multiple stressors such as pollution and habitat degradation, flow regulation, overfishing, and alien species. Against this backdrop, the paper evaluates the effectiveness of international environmental law in guiding domestic regimes, highlighting that where international law is imprecise/fragmented and/or contradictory, it can hinder the development of successful State practice. This paper collects and analyses information available from the CBD national reports to consider what members themselves have identified as their regulatory strengths and weaknesses. While the threats to biodiversity posed by IAS have been extensively documented, to date no study has examined States’ perceptions of their own IAS regimes. CBD, specifying how they are fulfilling their international obligations with respect to IAS. ![]() Members are also required to lodge national reports with the secretariat of the. Article 8(h) of the Convention on Biological Diversity (CBD) requires the contracting parties to ‘prevent the introduction of or control or eradicate those alien species that threaten ecosystems, habitats or species’. Invasive alien species (IAS) are alien species that threaten ecosystems, habitats or other species. Sustainable eco system governance (SESG) from invasive alien species should be emphasized to avoid biodiversity disasters that will have an impact on food security and nutrition of human beings. – It is felt that few initiatives are being taken by International Union for Conservation of Nature (IUCN) and governance of eco system from IAS is a necessity. International boundaries are indeed porous to the intentional and unintentional movement of species from various eco systems in the country. – The paper lists the invasive alien species (IAS) are those that are transmitted from their own ecological niche and to a new niche due to human influence, which causes the biodiversity disaster. ![]() – The paper portrays the various identified alien species, the scale of invasion thereby resulting in biological disaster caused by. – The purpose of the paper is to analyze the different modes of species dispersal and the various types of alien species dispersed in the Indian peninsular region and its impact on the eco system and livelihoods. This is especially true of Doon Valley, which is part of the mega Himalayan 'hotspot' belt and is globally designated for priority of conservational activities in India. However, the occurrence of the present share of alien species and their naturalization cannot be considered safe for native and endemic flora. This relative proportion of exotic and native elements is irrespective of 28.8% endemic dicot species in Indian Himalaya and 40% exotics in the entire Indian flora. Interestingly, the statistical ratio of alien species was 45.69% for woody flora, while it was investigated 19.4% for herbaceous species. During this study, 308 woody and 128 herbaceous exotic species were identified and enlisted from various localities and 37.61% of these are of American origin. Both herbaceous and woody species are considered and their origin, habit, and families are investigated along with the socio-economic and ecological relevance of a few species. This communication is an attempt to prepare an up-to-date account of alien/exotic flora of the Doon Valley. Widespread and have direct, adverse impacts on public goods. Once introduced into a newĮcosystem, invasive alien species can become Medicinal or hygienic purposes in many places Jeopardize food security and native plants used for Values of natural wonders and sacred spaces, and Of disease, compromise the aesthetic and spiritual Species threaten human health through the spread Harmful chemicals and pesticides and adverselyĪffecting local livelihoods.
