Weeds are a major constraint to agricultural production, particularly in the developing world. Cost-efficient biological control is a self-sustaining way to reduce this problem, and produces fewer non-target effects than chemical methods, which can cause serious damage to the environment. This book covers the origin, distribution, and ecology of twenty model invasive weed species, which occur in habitats from tropical to temperate to aquatic. Sustainable biological control of each weed using one or more arthropods is discussed. The aim is to provide ecological management models for use across the tropical world, and to assist in the assessment of potential risks to native and economic plants. This is a valuable resource for scientists and policy makers concerned with the biological control of invasive tropical plants.

After five years of debates, consultations and negotiations, the European institutions reached an agreement in 2013 on the Common Agricultural Policy (CAP) for the 2014-2020 period. The outcome has major implications for the EU's budget and farmers' incomes, but also for Europe's environment, its contribution to global climate change and to food security in the EU and in the world. It was decided to spend more than EURO400 billion during the rest of the decade on the CAP. The official claims are that the new CAP will take better account of society's expectations and lead to far-reaching changes by making subsidies fairer and 'greener' and making the CAP more efficient. It is also asserted that the CAP will play a key part in achieving the overall objective of promoting smart, sustainable and inclusive growth. However, there is significant scepticism about these claims and disappointment with the outcome of the decision-making, the first in which the European Parliament was involved under the co-decision procedure. In contrast to earlier reforms where more substantive changes were made to the CAP, the factors that induced the policy discussions in 2008-13 and those that influenced the decision-making did not reinforce each other. On the contrary, they sometimes counteracted one another, yielding an 'imperfect storm' as it were, resulting in more status quo and fewer changes. This book discusses the outcome of the decision-making and the factors that influenced the policy choices and decisions. It brings together contributions from leading academics from various disciplines and policy-makers, and key participants in the process from the European Commission and the European Parliament.

The processes and consequences of household decision-making are investigated using multi-disciplinary research methods of decision analysis that involves statistical, mathematical, psychological, anthropological, and econometric techniques brought together in a holistic manner. This study is focused in the Ada and Selale regions of the Central Ethiopian Highlands. The technologies studied are fertilizer, improved crop varieties, pesticides, and cross-bred cows. Goals and strategies of households, institutions, access to information, indigenous knowledge, risk taking behavior, and their impacts on household decision-making were studied. Technology adoption was studied under a variety of controllable (e.g., allocation of labor) and uncontrollable (natural factors such as rainfall or government intervention) environments. The findings demonstrated that agricultural producers can attain greater increases in food production and the efficiency with which it is produced if they adopt at least two innovations. The study revealed that non-physical resources such as indigenous knowledge and institutions play a fundamental role on the ability of producers to achieve increases in food production. For development to be sustained, therefore, investments in physical resources should be matched with those in non-physical resources.

French Canadian workers who paddled canoes, transported goods, and staffed the interior posts of the northern North American fur trade became popularly known as voyageurs. Scholars and public historians alike have cast them in the romantic role of rugged and merry heroes who paved the way for European civilization in the wild Northwest. Carolyn Podruchny looks beyond the stereotypes and reveals the contours of voyageurs' lives, world views, and values.

"Making the Voyageur World" shows that the voyageurs created distinct identities shaped by their French-Canadian peasant roots, the Aboriginal peoples they met in the Northwest, and the nature of their employment as indentured servants in diverse environments. Voyageurs' identities were also shaped by their constant travels and by their own masculine ideals that emphasized strength, endurance, and daring. Although voyageurs left few conventional traces of their own voices in the documentary record, an astonishing amount of information can be found in descriptions of them by their masters, explorers, and other travelers. By examining their lives in conjunction with the metaphor of the voyage, Podruchny not only reveals the everyday lives of her subjects--what they ate, their cosmology and rituals of celebration, their families, and, above all, their work--but also underscores their impact on the social and cultural landscape of North America.
