Regional assessment of cumulative impacts in the Nacala Corridor, identifying benefits, key environmental and social risks, and actions to strengthen governance and sustainable development.
The Cumulative Impact Assessment evaluated the cumulative effects of the Southern Africa Trade and Connectivity Project (SATCP) and its interactions with existing and planned developments along Nacala Logistics Corridor (Zambia, Mozambique, and Malawi). Covering 32 projects over the 2015-2035 period, the assessment examined key components, including food security, health, connectivity, employment, land use conflicts, vegetation, water resources, soils, and climate resilience.
The study applied a multidisciplinary methodology that combined expert analysis with extensive stakeholder engagement. Field visits, interviews, and public consultations ensured that local knowledge and concerns were systematically integrated into the assessment.
Results identified improved regional connectivity as the most significant positive cumulative impact. The main adverse impacts were associated with loss of agricultural land, physical and economic displacement, vegetation degradation, and increased risks of soil erosion and land degradation.
To address identified cumulative impacts, a Cumulative Impact Management Plan (CIMP) was developed, incorporating, among other measures, ecosystem restoration, protection of agricultural resources, resettlement management, and environmental monitoring. The CIMP also recommended establishing a dedicated governance mechanism, building on the existing Nacala Development Corridor Management Committee, to coordinate implementation of the plan, monitor performance indicators, track progress against defined targets, and ensure transparent reporting of results.
