Sri Lanka: Adjusted savings, net forest depletion (% of GNI)

Key figures

What the numbers say

In 2021, Sri Lanka's adjusted savings, net forest depletion (% of GNI) fell 0 percentage points on 2020 (from 0.06% to 0.06%).

Across the 30 yearly changes before that (1991 to 2020), the average change was −0.01 percentage points and a typical year strayed about 0.04 percentage points from that (the standard deviation). This year's change was 0.2 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 0.72 percentage points in 1977 and the biggest yearly fall was 1.05 percentage points in 1979. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2012 to 2021 the straight-line trend is downward, about 0.00416 percentage points a year. A straight line explains 65% of the movement over 10 observed years.

What this measures

Net forest depletion is calculated as the product of unit resource rents and the excess of roundwood harvest over natural growth. This indicator is expressed as a percentage of Gross National Income (GNI) which is the total income earned by all residents within an economic territory during an accounting period. It is equal to gross domestic product plus earned income receivable from abroad minus earned income payable abroad.

Limitations: A positive net depletion figure for forest resources implies that the harvest rate exceeds the rate of natural growth; this is not the same as deforestation, which represents a change in land use. In principle, there should be an addition to savings in countries where growth exceeds harvest, but empirical estimates suggest that most of this net growth is in forested areas that cannot currently be exploited economically. Because the depletion estimates reflect only timber values, they ignore all the external and nontimber benefits associated with standing forests.

Regional and income-group figures are computed by the World Bank as a weighted average.
