Women Collecting Water in Rural Kenya Report They Would Prefer Doing Other Activities.

To expand and maintain water supply infrastructure in rural regions of devel​oping countries, planners and policymakers need better information on the preferences of households who might use the sources. What is the relative importance of price, distance and quality in a households decision to use a source? If a water source increases fees, perhaps to cover maintenance or planned replacement, how will the total amount of water abstracted and revenue collected change?

This study estimates the optimal rotation period of various tree species in Kenya and applies it in the management of lumbering forests through optimal synchronization of forest plantations to achieve a steady supply to lumbering firms. The optimal rotation period of three tree species, pine, cypress, and eucalyptus, was estimated using data from Kenya Forest Service. A combined application of Chang simple production model and ​ Faustmann​ model​ reveals the optimal biological harvest age is 25 years for pine, 25 years for cypress, and 14 years for eucalyptus.
