In 2012, the population of a country was 65 million and the projected exponential rate of increase is 5.2 per l ,000. If the environmental impact per GDP is reduced by 15% by 2040, how will this affect the GDP per capi maintained at the 2010 levels? ta assuming the total environmental impact in 2040 is CE 1610: Engineering and Sustainable Development

Explanation / Answer

I = PAT

dI/dt = dP/dT + dA/dt+ dT/dt

We are keeping technology constant,

Population changes by 5.2 every year P = P0 x ert = 65 x 2.728 x 0.0052 = 75.11 million

Change in population % = 15.55%

Change in environmental impact per capita GDP = -15% i.e Change in GDP/change in population = -15%

x/15.55 = - 0.15 ; x = -2.3325%
