INHAMBANE BAY, Mozambique— Along the shallow, sun drenched mudflats of Inhambane Bay, local women refer to the ocean as their machamba their household garden. For generations, these vast marine meadows have functioned as a critical cornerstone of food security, community identity, and economic independence. Today, however, an ecological crisis is unfolding beneath the tides, and the coastal women who rely on these ecosystems are bearing the brunt of the collapse.
New findings from the World Resources Institute (WRI) and Ocean Revolution Moçambique highlight a severe gender imbalance in how climate change and environmental degradation impact artisanal fishing communities. Over the past few decades, nearly half of Inhambane Bay’s seagrass meadows have vanished, decimated by increasingly violent tropical cyclones and compounded by heavy localized fishing pressures.
The Gendered Divide of Environmental Loss
While both men and women depend on the bay, deep seated social norms dictate exactly where and how they fish, creating vastly different exposures to ecological decline. Women work predominantly as gleaners and guínia (fine-mesh) net fishers. Bound to the near-shore shallows on foot due to domestic responsibilities and lack of capital, they operate in the precise tidal zones most vulnerable to rising sea temperatures, extreme weather, and habitat disruption. WRI research reveals that in several communities, the areas of seagrass loss overlap almost entirely with women’s historical harvesting grounds.
Men typically utilize boats, traps, and large beach seine nets to fish in deeper, offshore channels. This geographic mobility allows male fishers to bypass degraded shallows and target alternative marine habitats when local ecosystems falter.
The consequences for women extend far past economic strain. In these seagrass dependent communities, families rely on near shore catches for more than 9 out of every 10 meals containing animal protein. The collapse of the habitat has forced women to crowd into the remaining micro patches of healthy vegetation, resulting in drastically diminished catches of low value juvenile crabs and small shrimp.
Rigid Barriers to Climate Adaptation
Adapting to this shifting environment remains incredibly difficult for coastal women due to pervasive financial and structural barriers. Because men traditionally control household finances, women rarely have the resources to purchase the expensive vessels or larger mesh gear required to transition to offshore fishing.
Compounding this strain is the regulatory status of traditional practices. The guínia nets widely favored by women are technically illegal under Mozambican law due to their small mesh size, which inadvertently sweeps up juvenile fish. While enforcement has historically been lax, a national rollout of strict bans on beach dragging gear threatens these informal fishers with heavy fines and equipment seizures, leaving them without viable alternative livelihoods.
Furthermore women are largely locked out of formal seafood trade networks. Lacking access to refrigerated transport and higher education, female traders are restricted to selling catches door-to-door or in informal street markets, while male traders dominate lucrative contracts with regional hotels and restaurants.
Policy Blind Spots and the Road Ahead
The core issue stems from data invisibility. Female dominated maritime labor including near shore gleaning and post harvest processing is entirely unrecorded by national fisheries monitoring systems.
This total lack of representation leads to “gender-blind” conservation and marine planning policies. For example, recent seasonal shrimp bans intended to replenish wild populations severely cut off income and food sources for vulnerable households without offering any financial cushions or transition aid. Additionally, women remain heavily underrepresented in male dominated Community Fisheries Councils, barring them from directing local investments into essential infrastructure like local cold storage or ecosystem management training.
To address these systemic vulnerabilities, WRI is piloting its new Ocean Dependence Framework. The decision support tool maps out exactly how marginalized demographics utilize marine resources, helping planners design climate adaptation and blue economy agendas that actively protect rather than inadvertently penalize the coastal women holding these delicate food networks together.
