This paper develops a one-sector endogenous growth model in which renewable natural resources are postulated as both a factor of production and as a measure of environmental quality. We show that sustained economic growth and a non-deteriorating environment can coexist along the economy’s balanced growth path. Moreover, the output growth rate is positively related to the steady-state level of n...

There is a need to select high quality forage legumes that are acid soil-tolerant, drought resistant, and persistent under the close defoliation associated with intensive pasture systems in the humid tropics.
