Positive Development

'Net positive', from Positive Development (PD) theory, is a paradigm in sustainable development and design. PD theory (taught and published from 2003) was first detailed in Positive Development (2008), and detailed in Net-Positive Design (2020). A net positive system/structure would 'give back to nature and society more than it takes' over its life cycle. In contrast, conventional sustainable design and development, in the real-world context of excess population growth, biodiversity loss, cumulative pollution, wealth disparities and social inequities closes off future options. To reverse the overshoot of planetary boundaries, a 'positive Development' would, among other sustainability criteria, increase nature beyond pre-urban or pre-industrial conditions.
