The article examines the complex relationships between population, dev
elopment and the configuration of the natural and social ecosystem, an
d within this context, inquires about demographic and socio-economic t
ransition strategies. The whole world today is affected by unemploymen
t and social exclusion, which are features of our 'age of distributive
injustice' (Kothari, 1993). This means that we have to go beyond trad
itional job creation policies. There are four areas to be explored in
detail. The second green revolution might revitalize the rural world b
y making small farms viable again and promoting the large-scale use of
biomass for energy and industrial purposes. In urban ecosystems, recy
cling and the economical use of energy and water as well as the mainte
nance of infrastructure, equipment and buildings, constitute a source
of employment which is self-financing, at least in part, by the result
ing savings in resources. The social services deficit can be largely m
ade good by the use of labour-intensive methods of production. Paradox
ically, the poor countries are better placed to achieve this than coun
tries where average wage-levels are high. Lastly, public works, which
are absolutely necessary for ensuring that systems are competitive, of
fer considerable employment potential. The situation is therefore not
completely hopeless with regard to employment and to proactive social
policies which attack the underlying causes of social exclusion.
