Climate change is an important issue in Sri Lanka, and its effects threaten to impact both human and natural systems. Roughly 50 percent of its 22 million citizens live in low-lying coastal areas in the west, south, and south-west of the island, and are at risk of future sea level rise . [ 1 ]
In 2000, only 25% of the households in Sri Lanka got their water through pipes. Even the water that does come through the pipe from local suppliers is not monitored efficiently. This is why a part of the population does not get clean drinking water. [2] Sri Lanka's wastewater management requires a lot of work.
Carbonation slows down with increasing diffusion depth. [2] Carbonation has two antagonist effects for (1) the concrete strength, and (2) its durability: The precipitation of calcite filling the microscopic voids in the concrete pore space decreases the concrete matrix porosity: so, it increases the mechanical strength of concrete;
Concrete has immersed from natural resources into man-made processes; evidence of the use of concrete dates back over 8,000 years ago. Today, many construction companies and concrete manufacturers have cut the use of Portland cement in their mixtures due to its production process emitting significant amounts of greenhouse gases into the atmosphere.
Sri Lanka map of Köppen climate classification zones Sri Lanka is the nineteenth most water stressed country in the world. Sri Lanka's climate can be described as tropical , and quite hot. Its position between 5 and 10 north latitude endows the country with year-round warm weather, moderated by ocean winds and considerable moisture. [ 6 ]
The Uma Oya Hydropower Complex (also internally called Uma Oya Multipurpose Development Project or UOMDP) is an irrigation and hydroelectric complex in the Badulla District of Sri Lanka. Early assessments of the project date back to 1989, when the first studies was conducted by the country's Central Engineering and Consultancy Bureau.
The Mahaweli Development program (Sinhala: මහවැලි සංවර්ධන වැඩසටහන) is known as the largest multipurpose national development program in the history of Sri Lanka and is also considered the keystone of the government's development program that was initiated in 1961.
In 2019 a total area of 16.5% [2] of Sri Lanka was forested. In 2010, it was 28.8% [3] (and 32.2% in 1995. [4]) 9.0% [5] of Sri Lanka's forests are classified as primary forest (the most biodiverse form of forest and the biggest carbon sinks on Earth). Sri Lanka's forests contain 61 million metric tons of carbon in living forest biomass (in ...
