The type of baseline information required, including granularity and scope, depends on the site. A scoping exercise should be undertaken to establish the required scope, method and resources required for data collection, as well as information already available. Information collected should be relevant to the site and be able to inform the site’s decisions, plans, activities, control measures, and/or track relevant trends. The type of baseline data collected, and its level of detail, also depends on the type of potential social and human rights impacts and risks in the site’s Area of Influence, and therefore may change over time. Expert review of the baseline data collection method and scope is advised.
Baseline data typically consist of a combination of qualitative, quantitative, and spatial data from secondary, and where secondary data does not suffice, primary sources. Collecting baseline data can be a time-consuming and resource-intensive process. Sites should consider the required scale, detail and disaggregation of data required to allow risks and potential impacts to be adequately assessed and to compare with future monitoring in the Area of Influence.
Secondary data collection is desk-based and involves the collection of existing qualitative and quantitative data. Useful secondary data sources include: previous studies and assessments (e.g. EIA,
); local government information and statistics; national government information and statistics; local and international NGOs; media, UN and World Bank reports, etc.
Primary data collection must consider gender, age, ethnic, religious, etc. differences. Data collection strategies should be developed to consider data collection from different marginalised or vulnerable groups, allowing accurate information on all groups to be collected. There are several ways to collect primary data, including through:
- household surveys, which allow for quantitative data collection at the household and/or individual level using questionnaires.
- focus-group discussion, which allows for quantitative and/or qualitative data collection from talking to specific population groups. This may include livelihood or wealth ranking, community mapping, and/or Venn diagram development.
- key informant interviews, which allows for quantitative and/or qualitative data collection from specific individuals around a specific topic.
To assess potential cumulative impacts, baseline data should include relevant current and proposed projects and activities within the Area of Influence but not directly connected to the site.
Baseline data should be disaggregated by community and not just reflect the regional or national level, particularly where community characteristics are different. Where possible, local data should be compared to data aggregated to regional or national level to identify any variations. Baseline data must be accurate, factual and not based on opinions, though anecdotal evidence can be useful for understanding stakeholder perceptions on certain topics.
Baseline data does not have to be captured in long, text-based reports. There is significant value in maintaining an electronic database or data management system so that data trends, different combinations of relevant data, and other statistics can be easily assessed.
mapping should be used to represent data spatially wherever possible. Charts, graphs and infographics can also be used to interpret results and communicate findings. Any data limitations or uncertainties should be noted.
The external context review also includes a systemic vulnerability assessment (see 2.2 Task 5).
