Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity
AI summary Read the abstract
This study investigated the environmental impacts of COVID-19 lockdowns on plastic pollution and microplastic levels in ecosystems. The analysis revealed how reduced human activity during lockdown periods altered plastic waste generation and environmental contamination patterns.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based public policies. In this critical review we propose, we propose a strategic roadmap structured around five complementary pillars: (1) implementation of continuous and standardized monitoring programs; (2) methodological harmonization adapted to regional ecological and institutional realities; (3) priority assessment of ecological impacts on sensitive coastal ecosystems; (4) improved understanding of dispersal sources and processes through integrated source‐sink approaches; and (5) strengthening scientific and institutional capacity, reducing dependence on international laboratories. The framework articulates scientific production, regulatory instruments, territorialized funding strategies, and reconfiguration of international cooperation, focusing on technical symmetry and capacity transfer. By integrating technical, institutional, and financial dimensions into a scalable and adaptable model, we offer an operational pathway to territorialize global commitments, including the Global Plastics Treaty, and consolidate analytical autonomy and sustainable governance of plastics in the Global South.

Tackling plastic pollution together: Examples of international collaboration for the monitoring and reporting of microlitter (including microplastics).
AI summary Read the abstract
Researchers developed an international laboratory network of 15 facilities across Vanuatu, Belize, South Africa, Sri Lanka, the Maldives, Indonesia, the Philippines, and Malaysia through the Commonwealth Litter Programme and Ocean Country Partnership Programme, providing harmonized equipment, protocols, and training to enable comparable microplastic monitoring in Global South countries. This collaborative infrastructure approach demonstrates how large laboratory networks with standardized methods are essential for producing large-scale baseline assessments of microplastic pollution.

AI summary Read the abstract
Researchers described international laboratory networks established through the UK's Commonwealth Litter Programme (CLiP) and Ocean Country Partnership Programme (OCPP) to build scientific capacity for microplastic and marine litter monitoring in Global South countries. The study presents examples of cross-border collaboration that provided infrastructure, training, and standardised methodologies to enable partner nations to produce reproducible and comparable data on plastic pollution entering the oceans.
A breakthrough in the harmonization of microplastics monitoring protocols in latin american region
AI summary Read the abstract
This paper describes progress toward harmonizing microplastic monitoring protocols across Latin American countries, aiming to create consistent, comparable data from a region with significant plastic pollution challenges but historically fragmented scientific approaches. Standardized monitoring is a prerequisite for effective regional policy and for understanding how plastic pollution flows through South and Central American river systems.

Collaboration and infrastructure is needed to develop an African perspective on micro(nano)plastic pollution
AI summary Read the abstract
This perspective argues that understanding micro(nano)plastic pollution requires pan-African research networks and infrastructure, as current knowledge is dominated by studies from wealthier nations while low- and middle-income countries bear disproportionate impacts from mismanaged plastic waste.
