Context

An Environment and Social Impact Assessment (ESIA) is applicable for projects that have been identified by the Environmental and Social Management System (ESMS) screening as high or moderate risk projects, requiring full or a partial ESIA respectively. The purpose of the ESIA is to assess and predict potential adverse social and environmental impacts and to develop suitable mitigation measures, which are documented in an Environmental and Social Management Plan (ESMP). The scope and depth of the ESIA depends on the nature, complexity and significance of the identified issues, as established by the ESMS screening. For a full ESIA the scope is defined by a scoping study which involves relevant stakeholders to confirm the risks identified by the ESMS screening, to set priorities for the ESIA and to determine the types of assessments required for the ESIA.

Key elements of an ESIA and an ESIA report

  1. Non-technical summary

  2. Project description

  3. Analysis of policy, legal and administrative framework

  4. Stakeholder identification and analysis

  5. Environmental and social baseline

  6. Assessment of environmental and social impacts

  7. Analysis of alternatives

  8. Environmental and social management plan (ESMP)

  9. Results of stakeholder consultations

Key Steps in Environmental and Social Impact Assessment

Other items to be specified in the terms of reference for an ESIA

  1. A summary of the main project features

  2. A list of applicable national and local ESIA requirements, where available and relevant

  3. A list of the key issues that emerged from the ESMS screening and scoping to be analyzed in the ESIA

  4. A description of the required elements of the ESIA and specification of the content of any additional specialist studies (if applicable) to be undertaken as part of the ESIA

  5. Provision of methodological guidance (if applicable) for the overall ESIA and specialist studies (e.g., gender responsive analysis)

  6. Specification of the type of environmental and social expertise required by the ESIA expert/team

  7. A preliminary list of feasible project alternatives including a “no project” option and requirements for their assessment

  8. Specification of types of required consultations with affected people, communities and other parties including final stakeholder meeting(s) for gathering views on the draft ESIA and ESMP

  9. The requirement for preparing an ESIA report and other documents or action plans (as needed) and for rigorously indicating accuracy, reliability and sources of the data used

  10. A budget and schedule for the ESIA providing sufficient time and funds for effective stakeholder consultation

As illustrated in the visual above, the ESMS is guided by eight overarching principles and four standards that reflect key environmental and social areas and issues at the heart of IUCN’s conservation approach. The principles and standards form the core of the ESMS Policy Framework, which governs the ESMS and determines the minimum environmental and social requirements for IUCN projects. The ESMS review procedure also provides for capturing possible other social and environmental risk issues as well as risks from projects failing to adequately address impacts from climate change and as such increasing the vulnerability of ecosystems and local communities.
