The environmental impact of population dynamics is not only from the number of population, but also, and more importantly, from quality of the population, per capita consumption, and technology (including behaviour). If we insist to reduce the negative environmental impact of the number of population, then we should concentrate on the reduction of the number of population among those with the highest per capita consumption. Should we promote further reduction in fertility among those who do not have environmentally friendly consumption?
Otherwise, we can also change their behaviour. If their consumption is not environmentally friendly, then they should be the first target to change their behaviour. This change in behaviour will motivate business to produce environmentally friendly goods and services. Then a continuing large number of population with rising human capital will become an important asset for the creation of environmental sustainability.
Family planning programmes should be strengthened with right-based approach, rather than as a means to speed up fertility decline and, then reduction in population growth rate.
Finally, to make an effective development programme, demographic information will help policy makers to know the future number and sex-age-education composition as well as spatial distribution of the people. Population is both the consumers and producers in development programmes (including those on environmental sustainability) and we therefore should know their size, age-sex-education composition, spatial distribution and how they change over time.
