A discussion is presented of the environmental impacts of farming systems which raise concerns about long-term sustainability. The challenges vary greatly in intensive irrigated systems, intensifying rainfed systems in high potential and environmentally fragile areas and the agricultural frontier. Theories of induced innovation suggest that microeconomic changes associated with population growth may themselves encourage technological and institutional innovations in natural resource management. Empirical evidence from tropical hillsides confirms these potentials. However, the pace of innovation is too slow relative to population and market growth. Public policies to promote land-improving technologies, foster social institutions needed for good resource management, and enhance resource values through public investments and price policies are essential to accelerate the process and prevent ecosystem degradation and impoverishment as populations increase.
