Sri Lanka

Sri Lanka is a tropical island nation situated in the Indian Ocean. Due to its close proximity to the equator, Sri Lanka is prone to hot climates – with temperatures averaging (monthly) between 22°C (72°F) and 33°C (92°F) in the lowlands, as well as wet climates via the occasional monsoon rainfall – averaging more than 50 inches (1,270 mm) per year in most parts of the country.

The country is also a bustling haven of flora and fauna – with a sizable portion of its land area occupied with forests, grasslands, and a dozen of major rivers.

Like many countries, Sri Lanka is also experiencing the adverse effects of climate – caught between harmful droughts from the hot seasons and destructive floods brought on by the wet season’s heavier rainfalls. Roughly 50 percent of its citizens living in low-lying, coastal areas are also in danger of the potentially-imminent sea level rise – a similar dilemma faced by many other island nations with such vulnerabilities.

About the location

Viewed from the main highway and the “Fool’s Bridge” – a frequently visited tourism spot, this location is a virgin field enriched with red lateral soil, which is ideal for scrub forests and pastures. As it has remained untouched by human activities, along with an initial zero-carbon footprint, it can be catered to SPE’s specific planting techniques. The consistent rainfall in the vicinity is an enabler for SPE’s rainwater harvesting system, while irrigation is gravity-fed, hence accumulating zero energy and electricity in SPE’s operations. As it already holds a high reputation for its adventure and nature park hiking trails, its prominent elevation location also makes it a suitable spot to garner attention towards SPE’s activities, and even more so once a carbon sink park is established there.
