Investigating Health Impacts of Natural Resource Extraction Projects in Burkina Faso, Ghana, Mozambique, and Tanzania: Protocol for a Mixed Methods Study

Abstract

Background Natural resource extraction projects offer both opportunities and risks for sustainable development and health in host communities. Often, however, the health of the community suffers. Health impact assessment (HIA) can mitigate the risks and promote the benefits of development but is not routinely done in the developing regions that could benefit the most. Objective Our study aims to investigate health and health determinants in regions affected by extractive industries in Burkina Faso, Ghana, Mozambique, and Tanzania. The evidence generated in our study will inform a policy dialogue on how HIA can be promoted as a regulatory approach as part of the larger research initiative called the HIA4SD (Health impact assessment for sustainable development) project. Methods The study is a concurrent triangulation, mixed methods, multi-stage, multi-focus project that specifically addresses the topics of governance and policy, social determinants of health, health economics, health systems, maternal and child health, morbidity and mortality, and environmental determinants, as well as the associated health outcomes in natural resource extraction project settings across four countries. To investigate each of these health topics, the project will (1) use existing population-level databases to quantify incidence of disease and other health outcomes and determinants over time using time series analysis; (2) conduct two quantitative surveys on mortality and cost of disease in producer regions; and (3) collect primary qualitative data using focus groups and key informant interviews describing community perceptions of the impacts of extraction projects on health and partnership arrangements between the projects and local and national governance. Differences in health outcomes and health determinants between districts with and without an extraction project will be analyzed using matched geographical analyses in quasi-Poisson regression models and binomial regression models. Costs to the health system and to the households from diseases found to be associated with projects in each country will be estimated retrospectively. Results Fieldwork for the study began in February 2019 and concluded in February 2020. At the time of submission, qualitative data collection had been completed in all four study countries. In Burkina Faso, 36 focus group discussions and 74 key informant interviews were conducted in three sites. In Ghana, 34 focus group discussions and 64 key informant interviews were conducted in three sites. In Mozambique, 75 focus group discussions and 103 key informant interviews were conducted in four sites. In Tanzania, 36 focus group discussions and 84 key informant interviews were conducted in three sites. Quantitative data extraction and collection is ongoing in all four study countries. Ethical approval for the study was received in all four study countries prior to beginning the fieldwork. Data analyses are underway and results are expected to be published in 2020 and 2021. Conclusions Disentangling the complex interactions of resource extraction projects with their host communities requires an integrative approach drawing on many methodologies under the HIA umbrella. By using complementary data sources to address the question of population health in project areas from several angles, bias and missing data will be reduced, generating high-quality evidence to aid countries in moving toward sustainable development.

Health impacts of industrial mining on surrounding communities: Local perspectives from three sub-Saharan African countries

“…This study was conducted as part of a mixed methods and multi-country research project, aiming to promote Health Impact Assessment (HIA) practice in sub-Saharan Africa [ 28 , 29 ]. Quantitative data from existing routine health data (e.g.…”

How to bring research evidence into policy? Synthesizing strategies of five research projects in low-and middle-income countries

“…In this r4d project, stakeholders were involved from the outset through their participation in the project launch meeting and in regular consortium meetings. The project is a collaboration between the Swiss Tropical and Public Health Institute (Swiss TPH), the Center for Development and Cooperation (NADEL) at the Swiss Federal Institute of Technology in Zurich/Switzerland and national research institutes, namely the Institut de Recherches en Sciences de la Santé in Burkina Faso, the University of Health and Allied Sciences in Ghana, the Centro de Investigação em Saúde de Manhiça in Mozambique and the Ifakara Health Institute in Tanzania [ 21 ]. The involvement of key stakeholders from the government, civil society, private sector and research community in an engaged dialogue from the beginning iss of central importance in this project, as in most cases mining is a highly politicized topic.…”

Water and health in mining settings in sub-Saharan Africa: A mixed methods geospatial visualization

“…This data triangulation was realized within the framework of a larger research project, aiming to generate sound scientific evidence to promote the use of Health Impact Assessment (HIA) in sub-Saharan Africa (Farnham et al, 2020;Winkler et al, 2020). This visualization along with other audio-visual material was produced to communicate the multi-layered research results to a broad audience and facilitate an informed and effective policy dialogue.…”

“…In the frame of a multi-country research project, we combined quantitative and qualitative data (Figure 1) (Farnham et al, 2020;Winkler et al, 2020). Quantitative data were used to analyse the trends in access to different water sources (i.e.…”
