  • Transition-Movement-In-Dorset.Pdf
    Abstract Global environmental problems such as climate change have highligted the need for succeeding in what decades of campaining by conventional environmental organisations seem to have failed to truly accomplish, changing environmental behaviour. The success of commmunity initiatives, such as the Transition Movement, in realising such change in environmental behaviour has sparked the interest of policymakers, practitioners as well as academics (Jackson 2005). Yet despite this interest, relatively little research has been carried out to explore the processes involved in the work of such initiatives (Seyfang 2007). This study set out to address that gap by critically evaluating the key achievements and challenges of the Transition Movement in Dorset by the means of a mixed-method comparative case study. The main data collection method was a creative and participatory self- evaluation workshop based on the principles of empowerment evaluation designed to provide Transition Initiatives with a useful and relevant tool for reflection while creating valuable qualitative data for this study. Through qualitative analysis of the outputs of the workshops it was established that the Transition Movement has formed a strong network of motivated and enthusiastic Initiatives in Dorset and shows great potential for growth and development. Due to evident commitment to the Transition Model, the main challenges and achievements of the Initiatives were related to the Model. While the supportive and positive atmosphere of the Initiatives as well as their ability to reconnect the community and engage a diverse range of people were seen as their strenghts, the groups were found to struggle with accomodating the different people involved in the groups as well as balance the non hierarchical structure of the Transition Model and the control and organisation necessary to steer the group forward.

  • Impacts of the Transition Movement
    Overview of responses from the Transition movement evaluation survey Impacts of the Transition movement Image: Mike Grenville March 2021 1 In November 2020 Transition Network launched an evaluation of the impact, relevance and potential of Transition. Our survey was open during November 2020, gathering 377 responses from 32 countries. This document presents an emerging, “rough analysis” overview of the survey responses, in relation to impacts. A separate companion document presents the overview in relation to relevance and potential. There are other aspects we will continue to analyse, including evaluation reports sent in by Transition groups, the discussion groups held in December 2020, and academic papers. We will also be organising further ways to explore and discuss the emerging analysis. _______________ The first section of this report describes the story so far of the Evaluation project, where we are in an ongoing process. After this, there is a summary overview of who responded to the survey and some overview tables. We show a table summarising the self-assessed depth of impacts of Transition groups and Hubs, categorised against the draft Transition characteristics and, within that, different types of activity. The main part of the document then collates a range of examples of impacts, as shared in the survey, under each of the draft Transition characteristics categories. We briefly look at some of the factors that are being reported, that influence the impact of a Transition group or Hub. This report concludes with a section looking at how Transition groups and Hubs have responded to recent challenges and crises, in particular Covid-19, as well as political unrest and extreme weather events.

  • Zero Waste Couture Makes Its Debut at Ecobank 2019
    FOR IMMEDIATE RELEASE Zero Waste Couture Makes Its Debut At EcoBank 2019 The impact of the fashion industry and over-consumption took centrestage at this year’s EcoBank, which championed sustainable living and mindful consumption through showcases, a zero waste bootcamp, and a new Grab Bag Sale to raise funds for charity. Saturday, 2 March 2019—Five leading ladies from Singapore’s environmental scene took to the catwalk today in bespoke outfits upcycled from donated clothing at this year’s EcoBank Bazaar and Fashion 3R event to raise awareness of fashion’s damaging impact on the environment and the need to find more sustainable ways of consuming clothing. Actress Judee Tan, Managing Director of 100 Resilient Cities Lauren Sorkin, 938NOW deejay Charlotte Mei, Artist and Fashion Revolution’s Laura Francois, and Founder of Green Drinks Olivia Choong walked the sustainability talk at the Fashion 3R Eco Fashion Show as part of the launch of this year’s EcoBank at City Developments Limited (CDL)’s City Square Mall. The five, as well as Guest-of-Honour and Senior Minister of State for the Ministry of the Environment and Water Resources Dr Amy Khor, donned hand-crafted garments made from second-hand clothing donated to EcoBank. Designed by sustainability non-profit The Fashion Pulpit, five of the outfits are on display and for sale until Sunday, 3 March, with proceeds to go to EcoBank’s chosen charity, Arc Children’s Centre, to support children with cancer or other life-threatening illnesses and their families. Speaking at the launch, Dr Khor said, “I am heartened to participate in the second edition of Fashion 3R.

EXECUTIVE SUMMARY a) NGOs and BSAP NGOs are a resource for mainstreaming biodiversity values to the Hong Kong public. The NGO sector can draw on wide existing skills and networks of employees, volunteers, target groups and funding sources, especially in organising events and working with the media, in engaging with the public. NGO Focus Group members are keen to get involved in implementing BSAP, and BSAP would be a compelling purpose for wider NGOs, not just environmental groups, to engage with stakeholders. The NGO Focus Group’s aims are guided in particular by Aichi Target 1, being: to improve the status of biodiversity in Hong Kong, ultimately determining how to bring about a cultural shift in the appreciation of nature and the motivation to conserve it. b) Recommended strategy In our view, bringing about a cultural shift in the Hong Kong public’s appreciation of nature by 2020 means that the public: 1) is aware of biodiversity in their immediate vicinity (e.g. “Can you name five Hong Kong bird species?”); 2) understands the fundamental importance and value of the ecosystem services that biodiversity provides to their daily lives; and 3) is engaged in conserving it.

  • Eco-Governmentality: a Discursive Analysis of State-Ngos-Youth Relations in Singapore
    social sciences $€ £ ¥ Article Eco-Governmentality: A Discursive Analysis of State-NGOs-Youth Relations in Singapore Peili Pey and Md Saidul Islam * ID Division of Sociology, Nanyang Technological University Singapore, 14 Nanyang Drive, Singapore 637332, Singapore; [email protected] * Correspondence: [email protected] Received: 21 September 2017; Accepted: 27 October 2017; Published: 1 November 2017 Abstract: This article seeks to address the gap in representing micro-level civil society voices and contribute to literature on state-society relations in Singapore’s environmental movement. Given the present constraints of state-NGO communication and cooperation, the state and NGOs negotiate the restrictions by grooming youths as agents of change. Through in-depth interviews, it explores how environmentalism is represented differently through various discourses by the social actors; state, NGOs and youths. By using eco-governmentality as a framework and through discursive analysis, we argue that state-society cooperation in environmentalism is hindered by lack of clear and effective communication channels, as well as expertise and knowledge barriers. In addition, investing in youths has led to an altered dynamic of state-society relations and a greater variety in discourses on environmental advocacy. Owing to the youths’ capability for spreading social awareness and ideas, this is an area that requires open discussion in order to achieve better state-civil society cooperation. Keywords: environmentalism; eco-governmentality; youths; state; civil society; discourse; Singapore 1. Introduction This research is primarily interested in studying state-society relations in the field of environment. The paper aims to address the research question of whether there are common grounds for state-society cooperation and if so, what these common grounds are.
