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.

Invasive species are of signi?cant concern, especially in mega-diverse countries, because they cause negative e?ects such as loss of native biodiversity, ecological alterations, disease spread, and impacts on economic development and human health. In mainland Ecuador, information on invasive invertebrates in marine ecosystems is scarce. The objective of this study was to describe and locate the invasive species present in the rocky shores of the intertidal and subtidal zones along 10 areas (83 sites) covering most of the Ecuadorian coast during 2015–2016. Benthic macroinvertebrates communities were measured over quadrats located randomly on a 50 m transect positioned parallel to the coast in the intertidal and subtidal zone, covering an area of 1,860 km2. Six invasive species were recorded: Arthropoda (Amphibalanus amphitrite), Cnidaria (Pennaria disticha, Carijoa riisei), Bryozoa (Bugula neritina), Rhodophyta (Asparagopsis taxiformis) and Chlorophyta (Caulerpa racemosa). The areas with highest abundance of invasive species were in Jama (not a protected area), Marine and Costal Wildlife Reserve Puntilla of Santa Elena and Santa Clara Island Wildlife Refuge (protected areas). The most abundant species was Carijoa riisei with a relative abundance of up to 80%. It was the most aggressive of the invasive species registered in the subtidal zone, mainly in northern centre of the Ecuadorian coast. C. riisei is growing on native coral (Pocillopora spp.) and on sessile macroinvertebrate communities (Pinctada mazatlanica, Muricea appresa and Aplysina sp.) that are being a?ected by its invasion. This study must be taken into account by local and regional government authorities to create public policy programmes of monitoring for surveillance and control of invasive species. These programmes should focus on integration of socio-economic and ecological e?ects. They should be complemented by experimental design and analysis of environmental variables to provide technical information for a baseline of bio-invasion analysis along the Ecuadorian coast and Galápagos, to avoid the expansion of invasive species negatively a?ecting the marine biodiversity of mega-diverse countries such as Ecuador and other countries of South America.
