    Kenya

    The relationship between land ownership and the sustainable use of natural resources is examined within the context of constitutional change in Africa. Using Kenya as an example, it is demonstrated that current constitutional arrangements put excessive emphasis on the protection of private property rights without requiring the corresponding duty of ecological stewardship. This has resulted in the failure of government policies and development practices to fully integrate environmental considerations into growth strategies.

    Land affected by a high water table displays waterlogging and salinity effects. This causes costs to farmers through additional land management problems, loss of soil productivity and results in a decline of the farm's capital value. A multi-period mathematical model is developed to investigate best land and financial management strategies for such farms. Water tables rise mainly due to ground water import caused by high recharge in the surrounding parts of the catchment.

    Cotton farmers in the Piedmont region incorrectly believe conservation systems with winter cover crop and no-till cultivation yield less than conventional systems. We model the effect of organic matter on productivity and show how ignoring this effect causes returns to be underestimated. Farmers with imperfect information underinvest in residue management.

    This paper examines the economics of urban expansion onto rural land in light of the sustainable management requirements of New Zealand's Resource Management Act. It finds that if conversion of land from rural to urban uses is practically irreversible because of the high cost of restoring rural qualities, it creates a user cost or inter-temporal externality which planning controls could address. Comparison of the methods for implementing such a policy show tradable development rights have high efficiency, but there are legal, practical and political obstacles to their use.
