The Reality of Sustaining Community-Based Sport and Physical Activity Programs to Enhance the Development of Underserved Youth: Challenges and Potential Strategies

Many community-based sport and physical activity programs take a positive youth development approach when operating in underserved communities around the world (Forneris, Whitley, & Barker, 2013). However, one of the biggest challenges for these programs is sustainability (Lindsey, 2008). The purpose of this article is to present the 3 authors’ experiences related to program sustainability when working with community-based sport and physical activity programs using a positive youth development approach in underserved communities. The authors describe the challenges faced with program sustainability, including ineffective development approaches, building strong relationships with community partners, knowledge translation, and securing funding. Also described are the strategies used to overcome these challenges, such as planning, capacity building, recruitment, and evaluation. This article is intended to stimulate more open and honest discussions about the realities of positive youth development program sustainability around the world.     

Integrating environmental sustainability into universities

Universities play a fundamental role in addressing global environmental challenges as their education, research and community involvement can produce long-lasting environmental effects and societal change. By demonstrating best practice in their operations, research and teaching, universities have both multiple and multiplier effects on society. For universities to comprehensively address sustainability, a ‘learning for sustainability’ approach needs to be embedded across every aspect of institutional operations in a synergistic way. Using semi-structured interviews, this research explored the factors that influence the integration of sustainability into the operations, teaching and research activities of universities in Australia and England. The research found that individuals, committed to the goal of a more sustainable world, play a vital role in the success of integrating environmental sustainability into universities. The factors critical to enabling universities to undertake the transformational changes necessary to embed environmental sustainability into all university areas included: a strong policy environment, resourcing of strategies, and encouragement of leaders and environmental sustainability advocates. Educating and building the awareness of university staff of the importance of environmental sustainability to future generations was key to a successful strategy.

Benchmarking the environmental values and attitudes of students in New Zealand's post‐compulsory education

How much do teachers in tertiary education know about the sustainability characteristics of their incoming students and, if this knowledge were to be available, how could their educational approaches be influenced by this knowledge? In New Zealand, Otago Polytechnic has committed itself to the goal that every graduate may think and act as a sustainable practitioner, and staff are changing their approach to teaching to achieve this. This research sought to benchmark the environmental worldview attributes of an incoming cohort of Otago Polytechnic students to support academic staff who need to know more about the sustainability interests and characteristics of their students, so that they may provide appropriate educational programmes. The research was also designed as the first stage of longer‐term research to evaluate the impact of these institutional changes on how students transform during the period of their tertiary education experience. The data and analysis presented here suggest that even before students start to study in the institution different groups have substantially different sustainability values‐sets. The authors anticipate that the research instruments and approaches used in the present study will contribute to a substantial national exploration of the sustainability value‐sets of tertiary students.

Understanding Environmental Education in the People's Republic of China: a national policy,locally interpreted

Since 1979 China has been attempting to reform its rather poorly functioning command economy, which suffered from a poor allocation of resources, a lack of incentives, irrational and arbitrary pricing, great waste of resources and a rigid and stultifying bureaucracy. At the same time there has been considerable acknowledgment for some time at the highest levels of Chinese government of the need to ensure environmental sustainability and this has been most recently confirmed in the form of ‘ten great changes’ needed in Chinese environmental thinking. This paper describes the processes whereby environmental policies are created and disseminated in China and points to some of the issues facing western educators who wish to work with Chinese colleagues in advancing global sustainability. It concludes that the problems facing environmental education in China may not be so very different to those elsewhere in the world.
