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.
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 ]
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;
It is also the primary threat to the survival of Sri Lanka's biodiversity. [2] Sri Lanka has 751 known species of amphibians, birds, mammals and reptiles of which 21.7% are endemic, and over 3314 species of vascular plants, of which 26.9% are endemic. [4]
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.
The tank cascade system (Sinhala: එල්ලංගාව, romanized: ellaṅgāva) is an ancient irrigation system spanning the island of Sri Lanka. It is a network of thousands of small irrigation tanks ( Sinhala : වැව , romanized: wewa ) draining to large reservoirs that store rainwater and surface runoff for later use.
In the past four years, the share of people living below the poverty line in Sri Lanka has risen to 25.9 per cent. The World Bank forecasts the economy to grow by just 2.2 per cent in 2024.
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 ...
