“Social impact assessment is predicted on the notion that decision-makers should understand the
consequences of their decisions before they act, and that the people affected will not only be appraised
of the effects, but have the opportunity to participate in designing their future.” (IGCP 1994)
A properly performed social impact assessment will answer the following questions: “what will happen if
a proposed action were to be implemented why, when, and where? Who is being affected? Who
benefits and who loses? What will change under different alternatives? How can adverse impacts be
avoided or mitigated, and benefits enhanced?” (Burdge, 2004:4).
INTRODUCTION
The social sciences have long been interested in the impacts to social and economic systems wrought by
large industrial, land-use, and environmental changes. Beginning in the early 1970s, a formalized set of
practices and procedures called Social Impact Assessment (SIA) emerged to document and/or predict
the socio-economic impacts from such large-scale projects. Originally developed in the U.S., through the
1969 National Environmental Policy Act (NEPA), the practice of SIA has changed and expanded since this
time.
While originally focused primarily on impacts to such variables as population, employment, and housing,
the scope of social and economic variables analyzed through SIA has greatly expanded, especially
overseas while the practice of SIA in the United States has waned, with new attention paid to the unique
contexts of indigenous populations, forced resettlement, military conflict, impacts to physical and
psychological health and wellbeing, and a new consideration to very long-term impacts related to
community sustainability (Vanclay and Esteves, 2011). These new types of impact analysis will require
the area of study to expand and its practitioners to increase their interdisciplinary knowledge and
expertise.
In the U.S., the 1970s represented somewhat of high point for the use of SIA. Through NEPA,
Environmental Impact Statements (EISs) were required in nearly all major land use decisions made by
U.S. government agencies, and court decisions and additional legislation clarified that managers must
analyze “reasonable and foreseeable” impacts to not only environmental concerns, but also to social
and economic attributes. By the mid-1970s, the expertise of social scientists was required in dozens of
land use decisions made by the federal government each year. Due in part to the U.S. oil embargo, the
1970s were also a period of widespread energy development, including oil, natural gas, coal, and
uranium in the western U.S., as well as expansion of the Tennessee Valley Authority hydroelectric dams
in the eastern U.S. Many of these projects were federally managed and caused significant
2
socioeconomic effects in the areas where they were sited, and many SIAs were produced on behalf of
the Federal Government because they were required under NEPA, while a host of additional SIA
documents were independently sponsored by state and local governments scrambling to manage the
adverse impacts. During this time, the U.S. Bureau of Land Management (BLM), among the largest
agencies directly affected by NEPA, had an estimated 45 social scientists under full time employment,
including dozens stationed at state and local offices (BLM 2011).
STEPS FOR A PROPER SOCIAL IMPACT ASSESSMENT
Following this flurry of SIA activity, several guidelines, handbooks, and textbooks for performing SIA
were produced by various government agencies, university professors, and private consultants; a set of
principles and best practices developed over time (Finsterbusch, 1980; Finsterbusch and Wolf, 1977;
Finsterbusch, et al. 1983; Leistritz and Murdock, 1981). The Guidelines and Principles For Social Impact
Assessment published in 1994 by the Interorganizational Committee on Principles and Guidelines for
Social Impact Assessment (ICGP) is perhaps the most well-known of these texts, and included many of
the most experienced and well-regarded SIA practitioners (IGCP 1994).
The IGCP identified 10 steps required to properly conduct an SIA within the U.S. NEPA framework.
1. Develop an effective public plan to involve all potentially affected publics.
2. Describe the proposed action or policy change and reasonable alternatives.
3. Describe the relevant human environment/area of influence and baseline conditions.
4. After obtaining a technical understanding of the proposal, identify the full range of probable social impacts that
will be addressed based on discussion or interviews with numbers of all potentially affected.
5. Investigate the probable impacts.
6. Determine the significance of the identified social impacts.
7. Estimate subsequent impacts and cumulative impacts.
8. Recommended new or changed alternatives and estimate or project their consequences.
9. Develop a mitigation plan.
10. Develop a monitoring program.
Nearly all SIA guides and texts contain a similar array of steps and principles that include public
participation, objective and scientifically valid methods, the development of mitigation strategies, and
other attributes commonly found in NEPA analysis.
DECLINING CAPACITY IN THE UNITED STATES
Despite a law that requires SIA in many instances, and the library of detailed guidelines and textbooks
available to SIA practitioners, the quality of the social and economic analyses produced in the U.S.
greatly varies, with many EIS documents failing to live up to the ideals presented in these texts (Burdge
2002).
The NEPA process places a high degree of importance on documenting and predicting impacts to
wildlife, habitats, and ecosystems, while social and economic impacts often receive a much less
stringent analyses (Burdge 2003). In comparison to impacts on the biophysical environment, measuring
and conceptualizing social impacts can prove to be more complex, and the prediction and/or
3
interpretation of the costs or benefits of such effects can be controversial (IGCP 1994). Rabel Burdge, a
preeminent practitioner of SIA, has described social impact assessment as the “orphan child” of the
NEPA process, as few people in federal agencies have either the expertise or desire to take responsibility
for producing quality social impact assessments.
Between 1983 to 2003, the amount of large-scale energy development in the United States dropped
precipitously, as did the demand for social science expertise related to SIA. Today, most federal agencies
have, at most, a handful of social scientists to oversee such matters nationwide, a small number
compared to the large amounts of environmental and wildlife expertise in such organizations. The BLM
in 2011, for example, had 14 employees trained in the social sciences, most of them part-time
employees, compared to 45 full-time employees in the 1970s (BLM, 2011). Today, the vast majority of
SIA work published by federal agencies is produced by independent contractors, many of them large
firms that may not actually visit the impacted communities they are analyzing. BLM increased the
requirements of social science in a 2006 instructional memo sent to BLM staff that stated, “In preparing
economic assessments, contractors shall utilize staff having at minimum a master’s degree in
economics; in preparing social assessments contractors shall utilize staff having at minimum
a master’s degree in a non-economic social science (sociology, anthropology, or geography). In both
cases contractors’ staff shall have at least two years’ relevant experience” (Dyer, 2006:1). The memo is
perhaps most notable because it illuminates the low level of requirements that were in place for more
than 30 years prior.
SIA in Oil and Gas and the Rocky Mountain West
The American West, with its large swaths of public land and a long history of mineral extraction, has
seen countless social impact assessments performed by federal agencies such as the Bureau of Land
Management and the U.S. Forest Service as part of permit applications for energy extraction and
resource management plan revisions.
In practice, given the declining capacity and oversight at federal agencies, the process is in many cases
pro forma. The basic array of easily-obtainable information such as population statistics, housing
numbers, and employment trends is presented as the existing social environment, while changes in
employment or tourism spending are estimated using econometric modeling. In the case of oil and gas
development, employment impacts typically are estimated using input/output models based on a range
of development scenarios. In not all cases are the intricacies of oil and gas workforces discussed, such as
the large non-resident worker populations or the leakage of earned wages and royalties to outside
areas.
In addition to impacts on employment, other key issues facing energy-impacted communities include
housing shortages, stresses on an array of municipal services (including not only roads, but emergency
response services, water and sewer infrastructure, etc.), impacts to social services, decline of tourism
and amenity-led development, and an over-dependence on mining economic activity that leaves the
community susceptible to a large economic downturn if the mining declines. More nuanced impacts
4
include changes to the community character and sense of place, which can lead to community out-
migration and disinvestment.
In theory, analysis under NEPA must estimate impacts to nearby communities and municipalities from
such activity, and also offer mitigation strategies to lessen these impacts. While commonplace in realm
of environmental impacts, such mitigation strategies are a rare occurrence in the area of social and
economic impacts. The Bureau of Land Management and other federal agencies defend this practice by
arguing the socioeconomic impacts occur outside of federal jurisdiction. While this may be technically
true, the source of the socioeconomic impacts occur on federal property and these actions could be
altered to remedy possible adverse impacts. Additionally, nothing prevents the NEPA documents from
offering voluntary mitigation strategies for other stakeholders to engage.
Local governments depend on such assessments for quality information to use for future planning, but
given uneasy histories between western local governments and federal agencies and a poor track record
of local relevancy, little faith is put into such estimates.
Increased Capacity in International Contexts
Meanwhile, as SIA has declined in the U.S. over the past several decades, SIA has become much more
important in international contexts. Starting in the mid-1980s and since greatly expanded, project
funders such as the World Bank and the International Monetary Fund require strict social and economic
monitoring and impact assessment protocols to assess the socioeconomic effects of grants that are
awarded, with additional evaluation required for projects that specifically aim to affect social or
economic goals at the local level (World Bank 2003). Additional funding agencies, such as the African
Development Bank, the Asian Development Bank, The United Nations, and the World Health
Organization, many national governments, as well as the European Union, also require SIA processes for
most large scale projects (Burdge, 2003). In the 1990s and 2000s, an array of texbooks, reports,
manuals, and the like were produced to guide SIA practitioners in international applications (Becker,
1997; Becker and Vanclay, 2003).
The international context is much more varied in the types of analyses performed than in the US. While
the US follows a set of strict and uniform legal requirements, the types and scopes of social impact
assessment that are required or preferred in international contexts can vary greatly, depending on the
funder, the nation, and the populations being impacted. Analyses can range from the effects of forced
resettlement, to measuring gender equity, to the social sustainability of indigenous populations (Vanclay
and Esteves, 2011). The protocols and best practices recommended for international contexts are
similarly broad, with such guidebooks often espousing general principles that should be adhered to, as
opposed to strict guidelines. In the early 2000s, a group of international SIA practitioners convened to
compose principles for SIA in international contexts, and included “core values” and “fundamental
principles”, reflecting the differing international realities of SIA.
5
Core values included:
1. There are fundamental human rights that are shared equally across cultures, and by males and females alike.
2. There is a right to have those fundamental human rights protected by the rule of law, with justice applied equally
and fairly to all, and available to all.
3. People have a right to live and work in an environment which is conducive to good health and to a good quality
of life and which enables the development of human and social potential.
4. Social dimensions of the environment specifically but not exclusively peace, the quality of social relationships,
freedom from fear, and belongingness are important aspects of people’s health and quality of life.
5. People have a right to be involved in the decision making about the planned interventions that will affect their
lives.
6. Local knowledge and experience are valuable and can be used to enhance planned interventions.
Fundamental Principles include:
1. Respect for human rights should underpin all actions.
2. Promoting equity and democratisation should be the major driver of development planning, and impacts on the
worst-off members of society should be a major consideration in all assessment.
3. The existence of diversity between cultures, within cultures, and the diversity of stakeholder interests need to be
recognised and valued.
4. Decision making should be just, fair and transparent, and decision makers should be accountable for their
decisions.
5. Development projects should be broadly acceptable to the members of those communities likely to benefit from,
or be affected by, the planned intervention.
6. The opinions and views of experts should not be the sole consideration in decisions about planned interventions.
7. The primary focus of all development should be positive outcomes, such as capacity building, empowerment, and
the realisation of human and social potential.
8. The term, ‘the environment’, should be defined broadly to include social and human dimensions, and in such
inclusion, care must be taken to ensure that adequate attention is given to the realm of the social.
The values and principles associated with international SIA reflect the variation in contexts, populations,
and legal requirements found in international contexts.
New Frontiers
The list of potential impacts on individuals and communities from environmental change is complex and
growing. Many of these impactsto health, climate, psychological wellbeing, human ecology, and
intergenerational well-beingare coming to the fore, but require an interdisciplinary expertise that falls
well beyond that harbored by most social sciences. The reverse is also true: many experts in these areas
(such as public health, climate implications, etc.) lack the social science backgrounds needed to
adequately integrate this expertise in the practices and products requisite of a social impact assessment.
These emerging areas also challenge the legal frameworks under which SIA may or may not be required.
The original NEPA legislation used terms such as “environment”, “human environment”, and “man’s
environment” to describe the realm of impacts that was required to be analyzed. These were ambiguous
enough: their full range and extent were not immediately clear and required additional lawsuits and
legislation before social and community impacts were required to be analyzed. Yet, court cases in the
U.S. have ruled thus far that social or psychological impacts alone are not enough to trigger an
Environmental Impact Statement under NEPA. Only the possibility of environmental impacts can trigger
6
an EIS; and, at that point, regulators must consider social impacts as well (Llewellyn and Freudenburg,
1989; Edelstein, 2003).
As new types of assessments, such as Health Impact Assessments (HIA), are becoming commonplace
ahead of land use decisions that bring the prospect of energy development, it is becoming more difficult
for government managers to determine the basis for requiring or not requiring such analysis.
Alternative Governance
Given the poor social science capacity and unclear legal requirements that constrain federal government
officials, it has often been left to non-federal organizations to raise the funds needed to perform quality
social impact assessments. State and local governments, academic organizations, environmental
organizations, and even industry itself have solicited many of the more robust and successful SIAs from
the 1970s to today. This has increasingly become the case, especially as new types of assessment are
requested that are not traditionally covered under NEPA.
The Emergence of Health Impact Assessment
In performing environmental justice analyses, the Environmental Protection Agency encourages
regulators and social scientists to incorporate Health Impact Assessments (HIA) into the NEPA process to
ensure that particular populations are not disproportionately harmed. The NEPA legislation explicitly
mentions health several times as an important attribute to be protected. The National Research Council
notes that “in theory” HIA is required under the NEPA process (NRC 2011).
In practice, however, HIA is almost never performed as a part of the NEPA process. The National
Research Council notes that the early 1970s NEPA lawsuits that shaped the legislation were not
concerned with health outcomes, and that most federal agencies have even less expertise in public
health than they do social science. HIA has been performed as part of a federal EIS process at least once
in the case of Alaskan Native populations (BLM 2012), but the instances are rare and HIA overall is not
often performed at the federal level in the United States. Instances of HIA solicited by state and local
American governments are growing, however, and internationally the use of HIA is much more common.
Today, its use is required in most planning decisions in some US states, many parts of the European
Union, many Canadian provinces, and other developed nations.
Conclusions
Social Impact Assessment is still a relatively young discipline and the importance of particular SIA
variables has continued to evolve. The requirements of SIA have changed in the past, and the idea of
adding procedures and analysis to what is required of social impact assessment as they emerge in the
scientific community is not new. In 1994, under executive order from President Clinton, analysis related
to environmental justice in minority and low income populations was made a requirement of EIS and SIA
performed under NEPA.
Today, a new emphasis on SIA has emerged in international contexts, while in the United States non-
federal organizations have been responsible for some of the more robust and in-depth analysis of
impacts to social, economic, and health outcomes at the local level. Recently, new types of energy
7
developments have emerged across the United States, giving rise to more opportunity, and more
demand, for impact assessments.

... Where one raises that it is said that there is environmental impact when an action or activity produces an alteration, favorable or unfavorable in the way or some of the components of the way. In the same way we can refer to the impact of a project on the environment, it is the difference between the current situation of the environment and future modified to the same one, as a result of the achievement of the project, that is to say, the positive or negative alteration in the quality of life of the human being, as resultant from a performance" (Bonilla and Esther, 2007). ...
... After contextualizing the concept of impact and organization, we them proceed to work with the intention of having the only term that serves to us as reference for it presents investigation. And thus we can define to the organizational impact like the change generated in the organization as a result of an innovation (Bonilla and Esther, 2007). On the other hand we can consider to the competitions and high levels of organizationalcapital, as the training and the experience, they turn out to be closely related to the strategies of innovation of an organization. ...

The process of evaluating the organizational impact is a subject widely studied nationally and internationally. The reference to the organizational impact, it is necessary to focus on the positive or negative results of a change, modification or innovation applied to the organization and that directly affects a part or the entire organization. The Conceptual Model for the Evaluation of the Organizational Impact (CMEOI) to determine the degree of knowledge of the objective, goals or projects, information and communication, effectiveness of specific programs or projects, motivation, benefits, stimuli or compensation, labor climate and identification of potential. The present investigation proposes a conceptual model that will be useful to determine the degree of organizational impact, of an entity in the face of any change, modification or innovation, whether internal or external.
... In the 1970s, the use of IAs became common practice in developed countries and extended beyond only environmental concerns to the inclusion of social and economic issues (Jacquet, 2014). By the mid-1970s, social scientists were frequently consulted for land use decisions, leading to the appearance of the term social impact assessment (SIA). ...

In order to balance resources between the tiers of the healthcare facility hierarchy in a way that ensures optimal healthcare provision, it is important that decisions concerning the expansion of the healthcare service provision network should align with a clearly defined strategy. In this paper, we evaluate the need for a custom framework for the retrospective assessment of the impact of a new healthcare facility. Perspectives from which a new facility are to be evaluated include: (i) the impact on the healthcare provision network as a whole; (ii) the impact on the total healthcare provision cost for the catchment area; and (iii) the impact on healthcare outcomes amongst the population that a facility serves. In order to evaluate the requirements of the new methodology, the basic structures of a range of existing methodologies are juxtaposed before establishing the healthcare indicators used in the annual health reports of three distinct countries.
... Social impact theories derive from the early 1970s and are based on public intervention which is prerequisite to ensure development and better development outcomes (Jacquet, 2014;Vanclay, 2003) 4 . A formalized set of good practices was developed and formalized in the US in the 1970s as the Social Impact Assessment, however surveys of McKinsey & Company state that the history of SIA started in the 1950s (McKinsey on Society). ...

Efcient infrastructure is a prerequisite of, and critcal to, development. Only some projects generate a positve rate of return, but all of them should generate positve non-economic impacts and contribute social gains. Social impact is considered as a consequence or efect of decisions or interventons which lead to development. It can also be considered as a social consequence of development. The main problem of social costs and benefts is that the impact is difcult to predict and quantfy and can be taken into account diferently by authorites, decision makers and project developers. The main purpose of the paper is to identfy and demonstrate a concept of the social impact of infrastructure projects. The principal methods used are a review of existng social science literature and surveys based on focus group interviews, devoted stakeholders of infrastructure projects, and their involvement at diferent stages of the project. The expected result is a set of outputs and outcomes which demonstrates social impacts (costs and benefts) related to stakeholders’ groups of the analyzed project.
Thesis
Abstract (Deutsch/English) Soziale Inkubatoren fördern Start-ups, die an Lösungen gesellschaftlicher Herausforderungen arbeiten, durch materielle und immaterielle Ressourcen, Beratung, Netzwerkkontakte und einen Zugang zu Finanzmitteln. Nur wenige Forschungsleistungen wurden bisher zum Thema der sozialen Inkubation, insbesondere zur Wirkung sozialer Inkubatoren, erbracht. Das Ziel der Thesis ist daher, ein theoretisches Verständnis von sozialer Inkubation zu erarbeiten, aber auch ein methodisches Instrument zu entwickeln, mit welchem eine Wirkungsevaluation für einen sozialen Inkubator durchgeführt werden kann. Für letzteres wurden die Stakeholder des Social Impact Labs Frankfurt hinsichtlich der Wirkungsziele, die sie mit dem Gründungsprogramm AndersGründer verfolgen, qualitativ befragt. Die Wirkungsziele wurden in eine logische Basis eingearbeitet, aus welcher mittels des Logical Framework Approachs eine Logframe-Matrix für das AndersGründer-Programm erstellt wurde. Diese bildet das hauptsächliche Ergebnis der vorliegenden Thesis und zeigt zudem die Übertragungsmöglichkeit des Logical Framework Approachs in das Feld um Social Entrepreneurship auf. Social incubators benefit start-ups that are solving societal challenges through tangible and intangible resources, mentoring, networking and an access to financing. Only a limited number of researches has been conducted in the field of social incubation, especially the impact of social incubation. The thesis objective is, therefore, to create a theoretical understanding of social incubation as well as developing a methodological instrument to measure the impact of a social incubator. For the latter, stakeholders of the Social Impact Lab Frankfurt have been surveyed regarding their impact goals, which they pursue with the incubation programme “AndersGründer”. The impact goals have been worked into a logical basis, out of which by use of the logical framework approach a logframe-matrix has been created. The matrix represents the main outcome of the thesis and shows the transferability of the logical framework approach into the field of social entrepreneurship.

This paper reviews the 25-year battle to have psychosocial impacts of contamination weighed in US administrative permit decisions. Despite the establishment of a professional literature and successful application in toxic torts, psychosocial (including psychological) impacts from the siting of hazardous environmental facilities have neither been reviewed substantively in environmental impact statements nor listed as an issue for adjudication in the issuance of permits by regulatory agencies. The reasons for this lag are explored through a detailed examination of key cases according to two sets of factors: personalistic versus environmental; and professional versus paradigmatic.

The goal of social impact assessment is to help individuals and communities, as well as government and private-sector organizations, understand and better anticipate the possible social consequences for human populations and communities of planned and unplanned social change resulting from proposed policies, plans, programmes and projects. Like all assessments, the SIA model is comparative. We look to similar settings for direction as to what will happen in the future. Based on decades of research, we have organized SIA indicators under the general headings of population characteristics, community and institutional structures, political and social resources, individual and family changes, and community resources. The SIA process identifies alternatives to a proposed action as well as guidelines for enhancement and mitigation.
Social impact assessment (SIA) has not been widely adopted as a component of the assessment process for project or policy appraisal. This paper focuses on four issues: how we are labeling research on social impacts; what historical events led to the separation of SIA from the environmental impact assessment (EIA) process; whether the Guidelines and Principles for Social Impact Assessment helped focus the research and practice of SIA; and whether there is evidence that we are accumulating a body of knowledge labeled social impact assessment. To become institutionalized EIA-SIA must be a statutory requirement, otherwise agencies and consulting firms that do EIA will not include social impacts. The requirement must extend to international bilateral aid, donor and lending agencies.

The passage of the National Environmental Policy Act of 1969 (NEPA) has been followed by a long series of judicial decisions clarifying and defining the applicability of the statute. Throughout the 1970s, most of these decisions indicated a relatively broad if not expanding view of NEPA's implications. Nevertheless, in a key decision—Metropolitan Edison Co. v. People Against Nuclear Energy (PANE)— the Supreme Court ruled that the Nuclear Regulatory Commission was not required to issue an environmental impact statement before restarting the undamaged nuclear reactor at Three Mile Island. The verdict was interpreted by many as narrowing NEPA's requirements for agencies to consider the social science implications of their activities; others saw the verdict merely as reaffirming the existing regulations of the Council on Environmental Quality that social and economic impacts by themselves do not require the preparation of an environmental impact statement. The article reviews the PANE decision, the legal commentaries on that decision, and the several years’ worth of additional case law that led up to the PANE decision and has accumulated since that time. The net result is a comprehensive analysis of the current cognizability or legal relevance of social science concepts in environmental impact statements.
Book
Large-scale industrial and energy-development projects are affecting the social and economic climate of rural areas across the nation. This creates a need for extensive planning information, both to prepare for the effects of such developments and to meet state and federal environmental-assessment requirements. This book examines alternative methods of modeling the economic, demographic, public-service, fiscal, and social impacts of major development projects. The authors provide a synthesis of the conceptual bases, estimation techniques, data requirements, and types of output available. They focus on models that address multiple impact dimensions and produce information at the county and subcounty levels. They also look at the kinds of data each model produces in each impact category. 366 references, 1 figure, 7 tables.
