Social and Economic Impact Assessment


Sierracon provides international best practice services in Social and Economic Impact Assessment.

Sierracon has extensive experience in providing survey teams to engage with communities to gather high-quality socio-economic baseline information. 

Based on the project design and prevailing policy and socio-economic conditions, we assess the nature, magnitude and significance of project-related social impacts and opportunities. 

We provide a clearly structured and transparent assessment – weighing impacts according to their probability; magnitude; timing and duration; the groups most likely affected; geographical scope; and potential for cumulative or cross-boundary effects.

Social and Economic Impact Assessments are undertaken not just to provide a snapshot of current conditions or to gain project approval - it is the basis for adaptive management strategies designed to ensure effective impact management and stakeholder engagement throughout the life of the project. 

Our social impact management planning includes clearly defined and prioritised actions; communications strategies; performance indicators; impact monitoring processes; and identification of project organizational capacities, staff, data management and training needs.

We provide specific services in undertaking agricultural impact assessments for proposed projects located in rural settings.

We also collaborate with environmental colleagues to deliver Environmental and Social Impact Assessments.
