This chapter explores ideas for developing an ecosystemecosystem approach to Future Generations Policy across three interconnected dimensions: systems and structuressystems and structures, culture and community engagementculture and community engagement, and individual leadership. The systems and structures we identified through our review of international case studies include constitutional measures, legislative initiatives and litigation, representation in parliament, international measures and adjusted norms and processes. Measures should aim for “institutional stickiness” through several factors, such as legal foundations that make mechanisms difficult to dismantle; broad political ownership that extends beyond any single party; public engagement that creates constituencies for long-term thinking; and demonstrated value that justifies continued investment. The second dimension of culture focuses incorporating long-term thinking into routine decision-making, assessment frameworks, and accountability mechanisms that guide public servants and ministers in their daily work. We review the elements of successful practice, which includes a government developing a clear vision with local relevance; strategic use of soft power; adequate resourcing; language localisation; ecosystem approach; legislative protection; cross-partisan commitment; and public engagement and buy-in. We review global mechanisms like citizens’ assemblies, youth parliaments, and community consultations anchor the agenda in public values. We suggest a new conception of successful leadership capability, with accountability and incentives realigned. On the other hand, our review also unearthed critical challenges to navigate. We summarise these under three broad themes: power balance dilemmas, sustainable resourcing models, and ensuring actions stem beyond government alone.
