To strengthen food sovereignty by building ecological knowledge, rights awareness, and community leadership particularly among youth and women through traditional practices, and critical engagement with policies and technologies affecting food systems.
“When the well is dry, we know the worth of water.”
– Benjamin Franklin
Aqua Ecology is not just a theory, but a living practice deep rooted in community knowledge and practices. We bring the natural way of life of fishing communities worldwide who are living with nature, highlighting their traditional and indigenous knowledge and practices…
“Water is the driving force of all nature.”

World famous scientist, philosopher and Artist
No Pure Water = No Clean and Nutritious Food
“NO CLEAN WATER : NO HEALTHY & NUTRITIOUS AQUATIC FOOD”
Protecting water bodies is therefore a fundamental requirement for food sovereignty within AquaEcology principles and the practice.
In Sri Lanka, many of our ecosystems were traditionally managed as commons shared spaces where communities collectively decided how to use and protect natural resources. Tanks, lagoons, coastal waters, forests, and grazing lands were not treated as private commodities. They were understood and primarily practiced as shared responsibilities
Rising sea levels and intensifying storms are driving ocean encroachment — the steady inland advance of seawater — at an alarming rate. This silent crisis erodes beaches, floods low-lying communities, and salinizes freshwater aquifers and farmland, threatening food security and drinking water for millions. Critical habitats like mangroves, salt marshes, and coral reefs are being lost, endangering marine biodiversity and the natural barriers that protect coastlines from storms.
Without proper conservation, restoration, and climate solutions, the ocean’s advance will reshape our world — and not for the better. Join us in protecting our blue planet before it’s too late
Oysters are highly efficient “biological filters”. A single adult oyster can filter up to 50 gallons (nearly 190 liters) of water per day. They draw water in through their gills using tiny hair-like structures called cilia. As the water passes over the gills, the oyster traps plankton, algae, bacteria, sediments, and even certain pollutants (like nitrogen and heavy metals) in a mucus layer. It then either consumes the nutritious particles or expels the rest as small clumps called pseudofeces, which settle to the bottom.
This process dramatically improves water clarity and quality by:
These includes:
Protecting these ecosystems ensures the continuity of “sustainable food production”, “biodiversity”, and “climate resilience”. It also recognizes that aquatic ecosystems must exist in harmony with surrounding landscapes including forests, grazing lands, agricultural fields, and habitats for birds and wildlife
Aqua ecology critically examines global and national trends affecting fisheries, including industrialization, overfishing, export-driven supply chains, and climate-related changes in fish stocks. It explores how policies and technologies linked to the Blue Economy and industrial fisheries can undermine small-scale fishers, damage ecosystems, and weaken local food security.
A key focus of Aqua ecology concept is understanding whole Aqua systems. It highlights the interconnections between rivers, tanks, wetlands, lagoons, coastal waters, forests, and agricultural landscapes. These ecosystems sustain fisheries, farming, biodiversity, and community livelihoods. The curriculum stresses the need to protect mangroves, coral reefs, sea weeds, seagrass beds, water catchment areas, and traditional tank cascade systems to ensure sustainable food production and ecological resilience.
Coral reefs occupy a tiny fraction of the ocean floor less than 1 percent, and often cited as closer to 0.1–0.2 percent yet they rank among Earth’s most vital ecosystems. Often called the “rainforests of the sea,” these living structures of calcium carbonate built by tiny coral polyps support extraordinary biodiversity, shield coastlines, sustain fisheries…
Along the tropical and subtropical coastlines of more than 120 countries, a unique group of salt-tolerant trees and shrubs thrives in the intertidal zone where land meets sea. These are the mangroves. Though they cover only a fraction of the planet’s forests—roughly 147,000 square kilometres, less than 1 percent of global tropical forest cover—they deliver…
Traditional and sustainable capture fisheries is comparable to hunting activities and hence involve an activity of procuring from nature – not grow, farm or harvest! This difference is important also to understand the pathway differences between the traditional agro-ecology framework and the need for an additional and more nuanced aqua-ecology framework and discourses around it. …
Seaweeds — often called the “forests of the sea” — are among the most important yet underappreciated organisms on our planet. These marine macroalgae (not true plants) quietly power entire ocean ecosystems, support coastal communities, help fight climate change, and offer sustainable solutions for food, industry, and agriculture. For a website dedicated to aqua-ecology like…
Sustainable fish harvest ensures that fish populations, marine and freshwater ecosystems, and the communities that depend on them remain healthy for generations. At Aqua-ecology.com, we focus on the intersection of aquaculture and ecological stewardship—balancing productive fish farming and responsible wild harvest with environmental protection. Overfishing, habitat destruction, pollution, and climate change threaten global fish stocks,…
Food sovereignty in Sri Lanka is under increasing threat due to climate change, extractive development models, ecological degradation, and policy frameworks that prioritize export led growth over local food systems. Coastal, lagoon, and inland fishing communities along with smallholder farmers are facing declining access to land, water, and resources essential for their livelihoods and cultural…
“Anyone who can solve the problems of water will be worthy of two Nobel prizes – one for peace and one for science.”
