The Science of Shade :Climate-Smart by Design

At Coromandel Coast, we are committed to transparency and scientific accuracy. Our shade-grown coffee is not just delicious—it is supported by rigorous research demonstrating significant benefits for biodiversity, climate, and communities. 

Here is what the science tells us about the coffee you are enjoying.

BIODIVERSITY BENEFITS

Bird Species Diversity

Our shade-grown coffee farms support up to three times more bird species than sun-grown plantations.

Shade coffee systems create complex habitats that mimic natural forests, providing crucial resources for birds that would otherwise be lost in conventional sun-grown plantations. Research consistently shows that shade coffee farms serve as critical habitat corridors and refuges for bird diversity.

Habitat Preservation

Each hectare of our shade-grown coffee preserves habitat for over 100 species of plants and animals.

The multi-layered canopy and diverse vegetation structure in our shade-grown plantations create numerous ecological niches that support a wide variety of species, from soil microorganisms to mammals. Studies in comparable regions have documented exceptional biodiversity in traditional coffee agroforestry systems.

Biodiversity Hotspot Protection 

By choosing our coffee, you are helping to protect critical habitat for migratory birds and endangered species native to the Western Ghats biodiversity hotspot.

India's Western Ghats, where our coffee grows, is one of the world’s most important biodiversity hotspots. Our shade-grown practices maintain forest cover and preserve habitat connectivity that is essential for the survival of numerous endemic and threatened species.

CARBON & CLIMATE IMPACT

Carbon Sequestration 

Our shade-grown coffee systems sequester up to 39 tonnes of carbon per hectare in above-ground biomass alone.

The diverse trees in our agroforestry system capture and store significant amounts of carbon. This sequestration helps mitigate climate change while providing additional ecosystem benefits such as temperature regulation and moisture retention.

Carbon Storage Comparison

The diverse tree canopy in our coffee agroforests stores approximately four times more carbon than sun-grown coffee systems.

The substantial difference in carbon storage between shade and sun systems demonstrates the climate benefits of traditional agroforestry approaches. Our multi-layered canopy contributes significantly to carbon sequestration both above and below ground.

Carbon Loss Prevention 

By supporting traditional shade-grown methods, you are helping to prevent the 46-76% carbon loss that occurs when forests are converted to sun-grown plantations.

When forests or traditional coffee systems are converted to high-intensity sun plantations, massive carbon losses occur. By maintaining shade cover, our coffee production prevents this significant carbon release while preserving ecosystem integrity.

SOIL & WATER CONSERVATION

Erosion Control 

Our shade-grown coffee helps prevent soil erosion, protecting watersheds that communities depend on.

The complex root systems and leaf litter from shade trees dramatically reduce soil erosion compared to sun-grown systems. This protects water quality and ensures long-term productivity of the land while safeguarding downstream water resources.

Natural Fertilisation 

The natural leaf litter from our shade trees reduces the need for synthetic fertilisers by up to 30%.

Fallen leaves and plant material from shade trees create natural mulch that enriches soil as it decomposes. This organic matter improves soil structure and fertility, reducing dependency on external inputs while enhancing the coffee’s terroir characteristics.

Water Conservation 

Our coffee grows in harmony with nature, requiring significantly less irrigation than sun-grown varieties.

Shade trees moderate temperature extremes and reduce evaporation, creating a more stable microclimate that helps coffee plants thrive with less supplemental water. This natural efficiency becomes increasingly important as climate change intensifies water scarcity in many regions.

SOCIAL & COMMUNITY IMPACT

Traditional Knowledge Preservation 

Our shade-grown coffee supports traditional agroforestry knowledge and sustainable livelihoods for Indian farming communities.

Shade-grown coffee cultivation preserves traditional ecological knowledge and cultural practices while providing diverse income sources for farming families. Multiple harvests from shade trees complement coffee income and enhance food security.

Cultural Heritage 

Each bag helps preserve centuries-old farming practices that work in harmony with nature.

The agroforestry techniques used in our coffee production represent generations of accumulated wisdom about sustainable land management. By supporting these methods, you are helping to maintain cultural heritage and proven sustainable farming approaches.
