    Description: This innovative interdisciplinary study focuses on the history, science, and policy of tree planting and water conservation in South Africa. South Africa’s forestry sector has sat—often controversially—at the crossroads of policy and scientific debates regarding water conservation, economic development, and biodiversity protection. Bennett and Kruger show how debates about the hydrological impact of exotic tree planting in South Africa shaped the development of modern scientific ideas and state policies relating to timber plantations, water conservation, invasive species control, and biodiversity management within South Africa as well as elsewhere in the world. Forestry and Water Conservation in South Africa shows how scientific research on the impact of exotic and native vegetation led to the development of a comprehensive national policy for conserving water, producing timber, and protecting indigenous species from invasive alien plants. Policies and laws relating to forests and water began to change in the late 1980s and early 1990s as a result of political and administrative changes within South Africa. This book suggests that the country’s contemporary policies towards timber plantations, guided by the National Water Act of 1998, need to be reconsidered in light of the authors’ findings. Bennett and Kruger also call for more interdisciplinary research and greater emphasis on integrated policies and management plans for forestry, invasive alien plants, water conservation, and biodiversity preservation.

    Description: An instrument has been built to carry out continuous in-situ measurement of small differences in water pressure, conductivity and temperature, in natural surface water and groundwater systems. A low-cost data telemetry system provides data on shore in real time if desired. The immediate purpose of measurements by this device is to continuously infer fluxes of water across the sediment-water interface in a complex estuarine system; however, direct application to assessment of sediment-water fluxes in rivers, lakes, and other systems is also possible. Key objectives of the design include both low cost, and accuracy of the order of ±0.5 mm H2O in measured head difference between the instrument’s two pressure ports. These objectives have been met, although a revision to the design of one component was found to be necessary. Deployments of up to nine months, and wireless range in excess of 300 m have been demonstrated.
