Potential impact of climate change on the distribution of six invasive alien plants in Nepal.

Shrestha Uttam Babu

The biological invasions have been increasing at multiple spatial scales and the management of invasive alien species is becoming more challenging due to confounding effects of climate change on the distribution of those species. Identification of climatically suitable areas for invasive alien species and their range under future climate change scenarios areessentialfor long-term management planningofthesespecies. Using occurrence data of six of the most problematic invasive alien plants (IAPs) of Nepal (Ageratum houstonianum Mill., Chromolaenaodorata (L.) R.M. King & H. Rob., Hyptis suaveolens (L.) Poit., Lantana camara L., Mikania micrantha Kunth, and Parthenium hysterophorus L.), we have predicted their climatically suitable areas across the country under the current and two future climate change scenarios (RCP 4.5 scenarios for 2050 and 2070). We have developed an ensemble of eight different species distribution modelling approaches to predict the location of climatically suitable areas. Under the current climatic condition, P. hysterophorus had the highest suitable area (18% of the total country’s area) while it was the lowest for M. micrantha (12%). A predicted increase in the currently suitable areas ranges from 3% (M. micrantha) to 70% (A. houstonianum) with the mean value for all six species being 29% under the future climate change scenario for 2050. For four species (A. houstonianum, C. odorata, H.suaveolens and L. camara), additional areas at elevations higher than the current distribution will provide suitable habitat under the projected future climate. In conclusion, all six IAPs assessed are likely to invade additional areas in future due to climate change and these scenarios need to be considered while planning for IAPs management as well as climate change adaptation.

The Helping Islands Adapt workshop was held in Auckland, New Zealand between the 11th and 16th of April 2010 to support regional action against invasive species on islands, in order to preserve biodiversity and adapt to climate change. It arose from decisions under the Convention on Biological Diversity (CBD) relating to invasive alien species and island biodiversity, and was hosted by the Government of New Zealand with support from a number of partner organisations and countries. The workshop focused on four major island regions: the Caribbean, Coral Triangle, Indian Ocean and Pacific, and involved participation by 82 people from 24 countries and territories, and 29 national, regional and international organisations (see participants list in Appendix 5). The workshop was specifically designed to allow for the maximum exchange of experience and support between representatives from diverse island regions working in invasive species management. It also included a field inspection of one of the Department of Conservation‘s invasive species management projects on Rangitoto Island in Auckland‘s Hauraki Gulf. The workshop built on efforts under the Cooperative Islands Initiative, a partnership launched at the World Summit for Sustainable Development and the CBD 6th Conference of the Parties in 2002. Its intended outputs had been agreed by the organiser‘s steering committee and set out as a 'road map‘ that was used to ensure clarity of the workshop‘s intended purpose, outputs and outcomes. An overview of the workshop, its sponsors, participants and conclusions was developed during the workshop and submitted to the 14th ?Subsidiary Body on Scientific Technical and Technological Advice (SBSSTA 14) to the Convention on Biological Diversity (CBD) in Nairobi 10-21 May 2010. That report is provided in full in Appendix 5 to these proceedings.
Combating Climate Change in the Pacific: Regional Governance, agency and dependency

From the perspective of Pacific island states and territories (PICTs) much of the intense speculation and debate over climate policy seems irrelevant and immature given the oft-repeated warnings of the severe consequences for low-lying islands and atoll countries of climate change. The Pacific is not just ‘any region’ when it comes to climate change but rather, as Farbotko (2010) argues, is an ‘experimental space’ of climate change ‘canaries’. The position of the Pacific at the frontline of climate change has spurred voluminous research, however studies of the politics of climate change within the region is limited, particularly with regard to and regional processes. This paper explores the regional politics of climate change in the Pacific. Within the grand architecture of global climate governance, the region provides compelling new insights into the ways climate change is constructed, governed, and shaped by—and in turn shapes—regional and global climate politics. Through an exploration of regional governance as a strategy by which small vulnerable states respond to urgent crises, the paper explores both the potential and the limitations of collective action on environmental issues following the United Nations Climate Change Conference (COP21) in Paris 2015. We argue that evolving regional governance on climate change is mobilizing resources and finance to combat climate change. On the surface it appears to be a successful manifestation of solidarity among states and territories facing a shared fate. This solidarity has been institutionalized in three key regional organizations that mobilize resources climate change action through distinct policy narratives about the place of the Pacific in global climate crisis. These organizations also distribute these resources to members. As a result climate finance in the Pacific is mostly generated by multilateral rather than bilateral donors. However, despite this apparent demonstration of regional agency, beneath the surface regional climate governance is heavily dependent on donors for finance and expertise. This exposes a dual vulnerability of PICTs. They are extremely vulnerable to the impacts of climate change while also being extremely vulnerable to growing dependencies on donors to address these impacts.
