    Abstract: Investigations into Calabar beans (the dried ripe seeds of Physostigma venenosum) and their alkaloidal components compose a classical scientific journey throughout some one-and-a-half centuries and not only represent a fascinating aspect of the history of medicine but which is, moreover, still ongoing at the forefront of chemical and medical discovery. Those in particular involving its major such component, l-physostigmine, have led to an understanding of some of the fundamental mechanisms occurring in physiology, pharmacology and biochemistry and, either actually or potentially (by providing a template and thereby acting as a “lead compound”) have provided a useful treatment for a variety of neurological disorders associated with irregularities in cholinergic transmission in which augmentation of cholinergic activity has proved to be beneficial.

    Description / Table of Contents: Chapter 1. Introduction: Mangrove Systems Facing Enclosures, Markets and Social Inequality -- Chapter 2. Early History of Mangrove Management in Giao Lạc -- Chapter 3. Socialism, Cooperatives and Mangrove Management in Giao Lạc (1954-1985) -- Chapter 4. Impacts of Economic Renovation on Households and Coastal Ecosystems -- Chapter 5. Social Differentiation under Đổi mới Reforms -- Chapter 6. Conclusions.
    Abstract: This book presents a historical and ethnographic study of changing mangrove management in northern Vietnam over the past 100 years, grounded in a case study in the Red River Delta in northern Vietnam. The book shows that three primary socio-economic dynamics have affected mangroves: enclosure movements that have restricted access by different user communities over time, such as the exclusion of women; changing valuation of mangroves and their products and services; and social and class differentiation caused by privatization of once common resources. The result of these pressures have been erosions of norms, rules, and collective action to protect and nurture mangroves, leading to widespread loss of coastal forests. Sustainable mangrove management will require attention to these dynamics to address current-day land conflicts. The book will be of interest to policy-makers, practitioners, and academics and students in forest policy, management and governance; rural livelihoods; and globalization and agrarian change. .

    Description / Table of Contents: 1. Introduction -- 2. Sustainability of Land Use: A Systems Approach -- 3. Consequential life cycle framework and methodology for the integrated sustainability impact assessment of land-use systems -- 4. Discussion and Conclusions. .
    Abstract: This book provides a holistic framework for assessing the environmental and economic impacts of land-use strategies for a range of purposes, such as food, animal feed, biomass and biofuels, and timber. Using land for one purpose negates its use for any other competing purpose. Given that it is in limited supply, land needs to be optimised so that it can meet the increasing demand for crops of a growing and wealthier human population, while providing ecosystem services, such as carbon storage (i.e. climate-change mitigation). The framework is quantitative and includes various indirect effects, like indirect land-use change, and is a robust basis with which to assess global impacts from land-use decisions on climate change, ecosystem services and biodiversity. .
