Mediterranean forest - the idea is grounded in science

The idea is grounded in science.

Three years of academic literature, made readable.

What happens to the body in the soil

The biochemistry of decomposition - what research shows

An average 70kg body produces 28-42 liters of necroleachate after burial. In the calcareous soils typical of Israel, volatile fatty acids (VFAs) - acetic, propionic, butyric - are nearly fully neutralized within weeks due to high pH of 7.5-8.5.[1]

In a dry Mediterranean climate, decomposition differs fundamentally from European models: extreme moisture deficit slows putrefactive bacteria, leading to tissue desiccation. Full skeletonization occurs within 4-6 months under outdoor exposure - vs. two years in humid environments.[2]

Trees and fungi near the burial site accelerate mineralization and return nitrogen and phosphorus to the soil - a process known as the Cadaver Decomposition Island (CDI). Studies show significant changes in plant species richness near green burial sites after 3-5 years.[3]

Why the Judean Foothills - not a coincidence

Hydrogeological research shows that calcareous-clayey soil acts as a natural barrier to decomposition fluids. The DRASTIC aquifer vulnerability index for the Judean Foothills is rated low risk - among the lowest in Israel.[5]

Mediterranean climate with 450-550mm annual rainfall - ideal for Palestine Oak (Quercus calliprinos) that needs no irrigation after two years. A tree living 600 years, drought-resistant, and more fire-resistant than any other tree species in Israel.[6]

The graves no one visits

Israel contains hundreds of thousands of abandoned graves. Families who emigrated, were forgotten, or dispersed. Graves no one has visited in decades - grey stones in grey rows, in the sun.

Yaar Ad is the solution that prevents abandonment: when the tree is the grave, it continues living even without visitors. It adds to the soil, the air, the wildlife - it doesn't remain a silent stone. The forest grows wild even when no one visits.

The wild heart of the forest is there - at the center, where the first were buried. Old trees, shaded, with their own history already.

The question scientists are still studying

PFAS and pharmaceutical residues - scientific transparency

Modern bodies contain PFAS ("forever chemicals") in 97% of the population. There is not yet sufficient research on their fate in green burial specifically in Mediterranean soil.[7]

"Scientific transparency is part of our commitment. Yaar Ad is committed to groundwater monitoring from opening day."

Carbon Sequestration - The Numbers

Every grave is also a tree. Every tree is also an active carbon store.

A mature Palestine Oak (age 20-40) absorbs an average of 12-22 kg CO₂ per year. In Yaar Ad's first phase - 3,000 trees - annual absorption at peak maturity is projected at 36-66 metric tons of CO₂.[3]

Projected 100-year cumulative

For comparison - conventional burial in a recycled wood coffin with an average concrete headstone emits 150-300 kg CO₂ per person. Each Yaar Ad burial thus doesn't just reduce emissions - it becomes a generational carbon asset.

Carbon market note: Yaar Ad is examining certification pathways through Verra VCS and Gold Standard. Carbon credits may become an independent revenue stream supporting perpetual site maintenance.
