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.

In nature, radiata pine is very localised and an obscure tree species despite the romantic character of much of its natural habitat. That obscure status and the lack of any reputation as a virgin timber slowed its due recognition as a commercial crop. Nevertheless, it has become a major plantation forest crop internationally. It has become the pre-eminent commercial forest species in New Zealand, Chile and Australia, with important plantings in some other countries. It consequently features prominently in the international trade in forest products, in addition to its importance in domestic markets of grower countries. Very fast growth, considerable site tolerances, ease of raising in nurseries and transplanting, and ease of processing and using its wood for a range of products and purposes, have made it the utility softwood of choice almost everywhere it can be grown satisfactorily. Abundant genetic variation and its amenability to other management inputs created special opportunities for its domestication. The story of its domestication forms a classic case history in the development of modern commercial forestry, with trailblazing in both genetic improvement and plantation management; this inevitably meant a learning process that provided instructive lessons, especially for tree breeders dealing with some other species. Paradoxically, the plantation monocultures have played and can continue to play an important role in protecting natural forests and other forms of biodiversity. Given the attractions of growing radiata pine, there were inevitably cases of overreach in planting it, with lessons to be learnt. Economic globalisation has meant globalisation of pests and disease organisms, and the scale on which radiata pine is grown has meant is has been the focus of various biotic alarms, none of which have proved catastrophic. Temptations, remain, however, to pay less than due attention to some aspects of risk management. The chapter structure of the book is based on historical periods, beginning long before any important human influences, and ending with a look into what the future might hold for the species and its role in human and ecological sustainability. Almost throughout, there has been complex interplay between the technical aspects, local social and economic factors, various types of institution, the enthusiasm and drive of some very influential individuals, and tides of economic ideology, threads that needed to be woven together to do the story justice.

Geologists, physicists and ecologists currently promote the idea of a post-Holocene epoch – the Anthropocene. As a result of constant innovation and modernisation in the fields of engineering, natural science, management studies and environmental studies there has been a growing awareness of the intrinsic interaction between humankind and the environment. Humankind has become part of the environmental dynamics, to the extent that they are literally able to change ecosystems. Nowhere is the impact more evident than in the anthropogenic engagement with the hydrosphere – from the smallest pool of water to the earth’s atmosphere. Comprehensive infrastructure development in water and sanitation, the growing trend to seek additional resources in the form of groundwater, desalinated seawater, and recycled wastewater, as well as special attention being given to capturing and preserving rainwater, bear evidence of a timely response to climate change, population growth and rapid development in many water-stressed regions of the world. The purpose of the book is to provide a historical overview of the manner in which South Africa’s water resources have been governed from a time when the Union of South Africa was formed, in 1910, up to 2008, a time of a growing global awareness of the potential impact that climate change may have on water resources in a key region of southern Africa, notable for increasing levels of aridity and more erratic rainfall patterns. This focus on the history of water affairs in South Africa makes it possible for scholars to comprehend the contemporary transitions made in the country’s water governance system since the establishment in 2014 of the Department of Water and Sanitation. The focus is on the Water–Energy–Food nexus, a strategy which holistically contemplates the governance and use of water from the perspective of the interconnection between water, energy and food as resources.

This assessment report is a component of the multiple-scale southern African sub-global assessment (SAfMA), which investigated the condition and trends of ecosystem services and human well-being in the Gariep basin from 1993 to 2003, as well as future scenarios and possible responses to ecosystem change. The assessment features highlights from four local-scale assessments nested within the basin: Sehlabathebe, Great Fish River, Richtersveld and the Gauteng Province.
