Book Description
Agricultural systems are no longer evaluated solely on the basis of the food they provide, but also on their capacity to limit impacts on the environment, such as soil conservation, water quality and biodiversity conservation, as well as their contribution to mitigating and adapting to climate change. In order to cope with these multiple service functions, they must internalize the costs and benefits of their environmental impact. Payments for ecosystem services are hoped to encourage and promote sustainable practices via financial incentives. The authors show that while the principle is straightforward, the practice is much more complicated. Whereas scenic beauty and protection of water sources provide benefits to the local population, carbon sequestration and biodiversity conservation can be considered international public goods, rendering potential payment schemes more complex. Few examples exist where national or international bodies have been able to set up viable mechanisms that compensate agricultural systems for the environmental services they provide. However this book provides several examples of successful programs, and aims to transfer them to other regions of the world. The authors show that a product can be sold if it is clearly quantified, there exists a means to determine the service's values, and there is a willing buyer. The first two sections of the book present methodological issues related to the quantification and marketing of ecosystem services from agriculture, including agroforestry. The third and final section presents case studies of practical payments for ecosystem services and experiences in Central and South America, and draws some lessons learnt for effective and sustainable development of ecosystem services compensation mechanisms.

Book Description
The ultimate gardening reference work compiled by two dozen of the world's leading plant experts under the auspices of one of the world's greatest botanical gardens. Brooklyn Botanic Garden Gardener's Desk Reference is a milestone in garden publishing, the kind of groundbreaking work that appears once in a lifetime. No gardening reference--ever--has combined this scope of information in a single volume. The coverage in most gardening reference books falls into a few standard horticultural categories. The Gardener's Desk Reference unlocks the door to a vast assortment of plant knowledge from around the world. There is enough information in this single volume to serve any plant enthusiast--beginning and professional alike--over a lifetime. For easy use, the wide-ranging material is divided into twenty different sections-- such as: Botany for Gardeners Kitchen Gardening The Horticultural Traveler Weights, Measures, and Conversions The hundreds of indispensable sidebars, graphs, tables, plant lists, maps, and illustrations found throughout the reference make it even more accessible and attractive. To do justice to the continent's breathtaking diversity of climates and plant communities, all plant lists are organized by region, and every recommended species or cultivar has been chosen by an experienced landscaper tested by years of gardening in the area. Never before have gardeners had access to the breadth and quality of information in this authoritative reference.

Book Description
Through a series of case studies, this third volume in the Earth series deals with the technological constraints and innovations that enabled societies to survive and thrive across a range of environmental conditions. The contributions are structured into three sections to draw out particular commonalities and contrasts in the choices made by pre-industrial communities in the construction of varied landscapes and cultural heritage: Landnam, from the Old Norse for ‘taking of land’, deals with colonization, including the drivers and processes through which colonizers developed an understanding of the productive potential and limitations of their new lands. Fields and field systems: Field-walls are a distinctive and apparently timeless characteristic of many pre-industrial farming landscapes but they present many the challenges to their study, such as the effects of plowing, abandonment and land-use change and of urban development in fertile lowland zones which may eradicate, reduce or conceal past systems of land-use and division. The importance of indirect and proxy evidence is illustrated and the value of interdisciplinary and modeling approaches emphasized. Agro-pastoralism: focuses on the complex ‘time-space adaptations’ devised for managing cultivation and livestock production, particularly the need to prevent stock incursions into arable fields during the growing season whilst making effective use of seasonal grazing resources. The contributions focus on mountainous areas, where temporary migrations, in the form of transhumance, provided access to a diversity of resources based around seasonal constraints on their availability and productivity.
