Social Impact Assessment Guidelines for Thriving Regions and Communities
Environmental Monitoring and Governance
Available Online
2022
These guidelines provide a practical approach to Social Impact Assessment (SIA). They are designed to help readers learn the basics about how to conduct an SIA, contribute to an SIA, use the results of an SIA, and judge if an SIA is fit for purpose. When writing the guidelines, we have assumed that readers may have little or no prior experience with SIA. The need for guidelines for SIA became apparent during our research with regional communities experiencing the social impacts of economic regeneration projects, including infrastructure, housing, irrigation, tourism and heritage conservation. During our work, we encountered many community leaders who were keen to learn how to assess the social impacts of the plans they design, how to take this information and use it to make decisions, and then, overtime, evaluate the outcomes for communities. When writing and testing the guidelines, we drew on our own professional expertise in SIA, and the experiences of potential guideline users including: community organisations, iwi members, central government agencies, local government economic development and planning professionals, infrastructure providers, sector groups, evaluation practitioners, consultancies, students, and academics. We also drew on the ideas of practitioners of SIA in conferences and training sessions1 , and other invaluable sources that are listed in the Annexes. SIA looks at the potential impacts of change proposal, focusing on who is affected, where and how, and what might be done to improve the results in the short, medium, and long-term. We expect that the guidelines will be useful for anyone proposing changes that affect people and communities, as well as those experiencing social impacts.

Insects have presented human society with some of its greatest development challenges by spreading diseases, consuming crops and damaging infrastructure. Despite the massive human and financial toll of invasive insects, cost estimates of their impacts remain sporadic, spatially incomplete and of questionable quality. Here we compile a comprehensive database of economic costs of invasive insects. Taking all reported goods and service estimates, invasive insects cost a minimum of US$70.0 billion per year globally, while associated health costs exceed US$6.9 billion per year. Total costs rise as the number of estimate increases, although many of the worst costs have already been estimated (especially those related to human health). A lack of dedicated studies, especially for reproducible goods and service estimates, implies gross underestimation of global costs. Global warming as a consequence of climate change, rising human population densities and intensifying international trade will allow these costly insects to spread into new areas, but substantial savings could be achieved by increasing surveillance, containment and public awareness.
