Across North and West Africa, artisanal dyeing and tanning remain deeply embedded in everyday life, shaping local economies, cultural identities, and social relations. In Algeria and Mali, these practices are not marginal activities but living traditions that connect generations, sustain households, and contribute to regional markets. From hand-dyed textiles to traditionally tanned leather goods, color and craftsmanship carry meaning far beyond aesthetics. Yet behind this richness lies a less visible reality: the growing pressure that artisanal production places on water resources and ecosystems, particularly through the discharge of untreated wastewater.
In both countries, artisanal dyeing and tanning are typically carried out in small workshops or household settings, often clustered in specific neighborhoods or craft districts. These activities rely on repeated washing, soaking, and rinsing processes that generate wastewater containing dyes, organic matter, salts, and sometimes heavy metals. Whether the dyes are derived from plants such as indigo or supplemented by synthetic compounds, the resulting effluents are frequently discharged directly into open drains, rivers, or onto surrounding soils. In contexts where sanitation infrastructure is limited or absent, this practice contributes to visible water pollution and long-term environmental degradation [1,2].
The environmental implications of such wastewater are well documented. Colored effluents reduce light penetration in surface waters, disrupting photosynthesis and aquatic food chains, while high organic loads consume dissolved oxygen during degradation processes, leading to hypoxic conditions harmful to aquatic organisms [3]. In tanning activities, chromium compounds and other chemicals may persist in sediments and soils, posing risks to ecosystems and human health [4]. Although comprehensive national monitoring remains limited in Algeria and Mali, localized studies and field observations consistently point to deteriorating water quality in areas hosting clusters of artisanal dyeing and tanning workshops [5,6].
These environmental challenges are closely intertwined with social and gender dimensions. Women play a central role in artisanal dyeing in both Algeria and Mali, particularly in textile preparation, dye extraction, fabric treatment, and finishing. In Mali, women-led cooperatives practicing indigo dyeing are recognized for preserving ancestral knowledge and generating household income, while in Algeria women are heavily involved in small-scale textile and leather finishing activities, often in informal settings [7]. This centrality exposes women disproportionately to contaminated water and chemical substances, frequently without adequate protective equipment. At the same time, women possess detailed knowledge of materials, plants, and production processes, making them key actors in the transition toward safer and more sustainable practices [8].
Despite their importance, women artisans often face structural constraints that limit their capacity to adopt cleaner production methods. These include restricted access to finance, limited technical training, weak integration into formal markets, and minimal involvement in environmental decision-making. Studies on gender and environmental governance in North and West Africa show that addressing pollution without tackling these inequalities reduces the effectiveness and sustainability of interventions [9]. Improving wastewater management in artisanal sectors therefore requires approaches that integrate environmental objectives with gender empowerment.
Beyond environmental and health pressures, artisanal dyeing and tanning in Mali is increasingly affected by economic instability l rooted in global market dynamics. Local craft products now compete with large volumes of low-cost, industrially manufactured textiles imported from Asia and Europe, which flood domestic and regional markets and undercut artisanal prices [17].This imported merchandise, often produced under economies of scale and weaker environmental constraints, erode the economic viability of traditional crafts.
As a result, artisans, particularly women operating in informal settings, are compelled to intensify production, reduce margins, and compromise environmentally safer practices to remain competitive. This economic pressure indirectly exacerbates water pollution and undermines health of the living systems, as cost-saving strategies frequently translate into increased reliance on synthetic dyes, reduced water reuse, and the absence of wastewater treatment measures.
Regional dialogue and field-based initiatives confirm this linkage between market vulnerability and environmental performance. Discussions during the Mali Symposium on Applied Sciences, MSAS 2024, highlighted how globalized trade and insufficient protection of localtvalue chains contribute to the fragility of artisanal livelihoods while simultaneously amplifying environmental risks in craft-intensive urban areas [17]. Similarly, real-world experiences documented under the Via Water program in Bamako show that artisans with improved market access, cooperative organization, and institutional support are more likely to adopt cleaner dyeing techniques and participate in collective wastewater management solutions [18]. These examples demonstrate that environmental threats in artisanal dyeing are often associated with broader issues of market access, fair competition, and economic resilience.
Conventional wastewater treatment technologies commonly used in industrial contexts are rarely adapted to artisanal production systems in Algeria and Mali. Such systems demand significant capital investment, technical expertise, and reliable energy supply, all of which are often beyond the reach of small workshops operating informally or semi-informally. As a result, untreated discharge remains the default option, reinforcing a cycle of environmental degradation and social vulnerability [10].
In this context, nature-based solutions have gained increasing attention as viable alternatives. These approaches use natural processes involving plants, soils, and microorganisms to treat wastewater in a decentralized and low-cost manner. Constructed wetlands, phytoremediation systems, and vegetated filtration channels can be integrated into artisanal landscapes, offering treatment options that are accessible, flexible, and environmentally compatible [11]. Their relevance is particularly strong in regions facing water scarcity and climate variability, where conventional infrastructure is difficult to deploy.
In Mali, a pilot initiative in the Segou region illustrates the potential of nature-based solutions for artisanal dyeing wastewater. A cluster of women-led dyeing workshops was discharging effluents into a small irrigation channel used downstream for agriculture. With support from local researchers and non-governmental organizations, a constructed wetland system was established using locally available materials and native plant species. Monitoring over several months showed a reduction in visible coloration, suspended solids, and organic pollution in the treated water [12].
Equally important was the participatory approach adopted, which involved women artisans in system design, plant maintenance, and basic water quality observation. This fostered a sense of ownership and strengthened awareness of the link between craft activities, water protection, and community health. Furthermore, a study presented at MSAS 2024 outlined how protein extracts from the Moringa Oleifera seeds could decontaminate artisanal dyeing effluents after significant removal of toxic pollutants, color, and turbidity via coagulation-decantation 17].
A comparable experience can be observed in northwestern Algeria, particularly in the Tlemcen region, where artisanal tanning activities have historically contributed to localized soil and water contamination. A pilot phytoremediation project, implemented through collaboration between a university research team and local artisan associations, introduced vegetated buffer zones along drainage pathways receiving tannery effluents. Species such as vetiver grass and sunflower were selected for their tolerance to contaminated water and their capacity to absorb or stabilize pollutants [13]. Preliminary assessments indicated improvements in water clarity and sediment retention, while the vegetated areas also enhanced the visual quality of the craft district. Training activities associated with the project targeted young artisans, including women, linking environmental management with skills development and employability.
These experiences demonstrate several advantages of nature-based solutions in artisanal contexts. They generally require lower investment and maintenance costs than conventional systems and can be adapted to seasonal variations in production and water flow. Their reliance on local materials and ecological processes increases cultural acceptance and long-term sustainability. Moreover, when implemented through participatory approaches, they contribute to social cohesion and women’s empowerment, reinforcing the link between environmental protection and inclusive development [14].
However, nature-based solutions are not without limitations. Their treatment efficiency depends on appropriate design, regular maintenance, and sufficient land availability. They may not remove all pollutants to levels suitable for unrestricted water reuse, particularly in cases involving heavy metals or persistent chemicals. Long-term monitoring is therefore essential to ensure environmental safety and to guide adaptive management. These challenges highlight the importance of institutional support, technical guidance, and integration into broader water and environmental policies [15].
At the national level, artisanal wastewater management remains insufficiently addressed in both Algeria and Mali, despite its cumulative environmental impact. Industrial pollution often receives greater regulatory attention, while small-scale activities are overlooked due to their informal nature. Recognizing the combined environmental and economic vulnerability of artisanal sectors opens opportunities for more integrated policies that link decentralized treatment solutions with market support mechanisms, gender-sensitive capacity building, and protection of local value chains. Such approaches can encourage collaboration between artisans, researchers, municipalities, and development partners [16].
Conclusion
The future of artisanal dyeing and tanning in Algeria and Mali depends on the ability to reconcile cultural heritage with environmental sustainability. Protecting water resources does not require abandoning tradition, but rather adapting practices through locally grounded innovation. By embracing nature-based solutions and placing women artisans at the center of change, communities can preserve the colors that define their identity while safeguarding the waters that sustain them. This convergence of craftsmanship, gender equity, and ecological restoration offers a compelling pathway toward a just and resilient transition.
