The Green Infrastructure Management Manual (GIMM) by the Institute of Public Works Engineering Australasia (IPWEA) provides asset stewards with knowledge, tools, and frameworks to include green infrastructure in strategic, asset, and financial planning.
The free e-book covers a range of assets including street trees, green roofs and walls, parks and gardens, urban forests, community gardens, living shorelines, hybrid reefs, seagrasses, saltmarshes, mangroves, and water-sensitive urban design features such as constructed wetlands, bioswales, and rain gardens. It provides guidance on valuation and condition assessment methodologies, co-benefits, service provision, demand management, lifecycle analysis, risk assessments, long-term planning, costs, threats, case studies, decision tools, and templates.
The manual is supported by an online training course with an industry-recognised micro-credential.
