Abstract

Los sistemas de andenería en los Andes centrales contribuyeron a la seguridad alimentaria y al desarrollo de las civilizaciones andinas prehispánicas. Actualmente el tejido socioeconómico andino está empobrecido, con escasa cohesión y falta de políticas coherentes que promuevan un desarrollo sustentable. El presente libro describe el origen de los sistemas de andenería en el contexto de cambio climático, geográfico, agroecológico y de ingeniería, así como su papel en la cultura y el patrimoni...

Abstract

La récente émergence du SRAS (syndrome respiratoire aigu sévère) rappelle la vulnérabilité de l’homme face aux maladies infectieuses. La diffusion possible de certains virus à l’échelle planétaire, liée au développement des transports et à leur rapidité croissante, fait que nous sommes désormais tous concernés. À travers de nombreux exemples, cet ouvrage présente le concept de virus émergents et analyse les facteurs qui favorisent cette émergence. L’homme y tient une place déterminante par les modifications majeures qu’il apporte à l’écosystème et par l’évolution très rapide de ses modes de vie (urbanisation, politiques de santé, pratiques socio-culturelles). Sont également exposées les propriétés évolutives des virus – en particulier des virus à ARN – au niveau biologique et moléculaire, qui jouent un rôle important dans leur adaptation à l’homme et leur diffusion. Quelles menaces pour le futur ? L’un des risques majeurs réside dans l’extrême diversité des virus découverts dans les zones tropicales, virus potentiellement responsables des maladies émergentes de demain. Seule l’implantation durable de centres de recherche et de surveillance dans ces zones peut permettre la détection précoce de ces nouveaux agents. L’expansion des viroses existantes est également analysée, ainsi que les risques entraînés par l’apparition de virus mutants, susceptibles de provoquer une nouvelle pandémie de grippe.

Abstract

Dans le Nordeste du Brésil, les petits agriculteurs du Sertao semi-aride sont fragilisés par des sécheresses récurrentes. Des chercheurs français et brésiliens ont mené une recherche interdisciplinaire sur les interactions entre ces sociétés rurales et leur environnement. Un double regard - celui des sciences sociales et celui des sciences de la nature - permet d'évaluer la viabilité écologique et sociale des stratégies paysannes pour la génération d'aujourd'hui et pour celles de demain. La menace de la sécheresse est appréhendée à une échelle régionale, puis locale. Deux visages du Sertao coexistent : l'un, qualifié de « traditionnel », continue à privilégier l'élevage extensif, mais se trouve confronté à une lente dégradation des pâturages de la caatinga ; l'autre, dit « moderne », fait le choix d'une agriculture irriguée et orientée vers le marché, mais bute sur la vulnérabilité des ressources en eau et des sols. Le suivi, pendant douze années, de deux groupes d'agriculteurs incarnant ces stratégies permet de comprendre et de comparer les logiques, les contradictions mais aussi les capacités d'évolution de chacun d'eux dans un contexte marqué par l'incertitude, tant climatique que socio-économique.

Abstract

Le fleuve Niger constitue un véritable poumon humide pour l’Afrique de l’Ouest et plus spécialement pour la république du Mali. Dans ce pays, la gestion du fleuve constitue un enjeu majeur car on y trouve à la fois de remarquables systèmes de production traditionnels associés au phénomène naturel de crue – sources de moyens d’existence pour des centaines de milliers de personnes – mais aussi de grandes réalisations et promesses en matière d’aménagements modernes, hydroélectriques et hydroagricoles. À l’heure où de nouveaux projets d’équipement arrivent à concrétisation et où d’autres sont annoncés, il est important de faire le point sur l’état de santé de ce fleuve et de peser ce qu’il représente pour ses multiples usagers. Cette expertise collégiale, conduite par l’IRD et l’IER et réalisée avec le soutien de plusieurs institutions d’aide au développement et de défense de l’environnement, traite de ces différents aspects avec pour objectif, d’une part, la clarification des cadres institutionnels et des options de politiques publiques et, d’autre part, le renforcement des outils de suivi et d’aide à la décision.

Abstract

Au Nord comme au Sud, l’accès à l’eau, que celle-ci soit à usage domestique ou agricole, devient de plus en plus difficile pour les populations pauvres, alors que les différents types d’exclusion se combinent pour accentuer les inégalités. Pour comparer les processus actuellement en cours sur les cinq continents et tenter d’inverser ces tendances, l’IRD a organisé en 2005 des rencontres à l’université d’Agadir avec l’appui du CRDI et de la Ford Fondation. Les chercheurs, décideurs et responsables d’ONG réunis à cette occasion proposent dans le présent CD un cadre d’action et invitent les pouvoirs publics à renouveler les politiques publiques et répondre aux revendications locales.

Abstract

In a worldwide context of ever-growing competition for water and land, climate change, droughts and man-made water scarcity, and less-participatory water governance, agriculture faces the great challenge of producing enough food for a continually increasing population. In this line, this book provides a broad overview of innovation issues in the complex water–agriculture–food nexus, thus also relative to their interconnections and dependences. Issues refer to different spatial scales, from the field or the farm to the irrigation system or the river basin. Multidisciplinary approaches are used when analyzing the relationships between water, agriculture, and food security. The covered issues are quite diverse and include: innovation in crop evapotranspiration, crop coefficients and modeling; updates in research relative to crop water use and saving; irrigation scheduling and systems design; simulation models to support water and agricultural decisions; issues to cope with water scarcity and climate change; advances in water resource quality and sustainable uses; new tools for mapping and use of remote sensing information; and fostering a participative and inclusive governance of water for food security and population welfare. This book brings together a variety of contributions by leading international experts, professionals, and scholars in those diverse fields. It represents a major synthesis and state-of-the-art on various subjects, thus providing a valuable and updated resource for all researchers, professionals, policymakers, and post-graduate students interested in the complex world of the water–agriculture–food nexus.

Abstract

De par leur richesse en ressources naturelles renouvelables, les zones inondables tropicales revêtent un intérêt social et économique majeur pour les pays en développement. Cependant, les fleuves tropicaux sont aujourd'hui de plus en plus aménagés pour satisfaire les besoins liés à de nouvelles activités. Les zones jusque-là régulièrement inondées par la crue annuelle se réduisent ou alors les rythmes de leur inondation sont profondément modifiés. Les impacts de tels changements sont nombreux et portent atteinte à la biodiversité et à la durabilité des systèmes d'exploitation. Il s'avère alors nécessaire de définir de nouvelles approches de la gestion de l'eau, des espaces et des ressources vivantes, qui tout à la fois préservent les écosystèmes et prennent en considération les besoins des différents usagers. Tel est l'objectif de cet ouvrage qui pose, dans un premier temps, la problématique sociétale autour de laquelle cette gestion doit être repensée, en faisant apparaître la diversité d'acteurs et d'institutions concernés. Il présente ensuite les acquis les plus récents de la recherche sur le fonctionnement de ces écosystèmes ainsi que sur les pratiques et stratégies déployées par les populations qui les exploitent. Enfin est abordée la question des instruments à mettre en place pour assurer l'effectivité d'une gestion durable des zones inondables tropicales : après avoir fait le point sur les apports de la recherche concernant les outils de traitement et de partage de l'information environnementale, l'ouvrage se termine par un débat sur les conditions de création et de fonctionnement des institutions de suivi, de concertation et de décision.

Abstract

Water, in its many guises, has always played a powerful role in shaping Southeast Asian histories, cultures, societies and economies. This volume, the rewritten results of an international workshop, with participants from eight countries, contains thirteen essays, representing a broad range of approaches to the study of Southeast Asia with water as the central theme. As it was exposed to the sea, the region was more accessible to outside political, economic and cultural influences than many landlocked areas. Easy access through sea routes also stimulated trade from an early age. However, the same easy access made Southeast Asia vulnerable to political control by strong outsiders. The sea is, moreover, a source of food, but also of many hazards. At the same time, Southeast Asian societies and cultures are confronted with and permeated by ‘water from heaven’ in the form of rain, flash floods, irrigation water, water in rivers, brooks and swaps, water-driven power plants, and pumped or piped water, in addition to water as a carrier of sewage and pollution. Finally, the volume deals with the role of water in classification systems, beliefs, myths, illness and healing.

Abstract

Water acquisition, storage, allocation and distribution are intensely contested in our society, whether, for instance, such issues pertain to a conflict between upstream and downstream farmers located on a small stream or to a large dam located on the border of two nations. Water conflicts are mostly studied as disputes around access to water resources or the formulation of water laws and governance rules. However, explicitly or not, water conflicts nearly always also involve disputes among different philosophical views. The contributions to this edited volume have looked at the politics of contested knowledge as manifested in the conceptualisation, design, development, implementation and governance of large dams and mega-hydraulic infrastructure projects in various parts of the world. The special issue has explored the following core questions: Which philosophies and claims on mega-hydraulic projects are encountered, and how are they shaped, validated, negotiated and contested in concrete contexts? Whose knowledge counts and whose knowledge is downplayed in water development conflict situations, and how have different epistemic communities and cultural-political identities shaped practices of design, planning and construction of dams and mega-hydraulic projects? The contributions have also scrutinised how these epistemic communities interactively shape norms, rules, beliefs and values about water problems and solutions, including notions of justice, citizenship and progress that are subsequently to become embedded in material artefacts.

Abstract

Neighbourhood landscapes are the quintessential forms of urban landscapes in most cities worldwide. They are pervasive, and hence experienced by the large majority of urban dwellers in their everyday life. More than parks, nature reserves or nature areas which are visited as destinations, neighbourhood landscapes provide the most immediate, frequent and convenient form of nature experienced by urban dwellers on a daily basis. They are also valuable as social spaces to bring residents together, foster social ties, and strengthen communities. Despite their importance, surprisingly little has been written to guide the planning and design of neighbourhood landscapes.This book is written for a specific purpose, to illustrate how the design of neighbourhood landscapes helps to deliver more benefits for urban dwellers and, at the same time, protect ecosystems that facilitate human well-being. This is in turn important as the synergistic relationships between human well-being, quality of biophysical urban environment, and health of human–environment interactions fundamentally underpin urban sustainability. The authors emphasize the role neighbourhood landscapes play in forging connections between people and nature, people and people, and people and place. Most of all, the book highlights the role of focusing on people in this endeavour, as it is only when landscapes are appropriately designed, and when people recognize these benefits, that they become valued and protected as a community resource.This book is organized into two parts. Part 1 focuses on the conceptual foundations that underpin the neighbourhood landscape design guidelines being developed. In this section, the authors describe the key concepts relating functions of neighbourhood landscapes to the key urban development goals of sustainability, liveability and reliance; how they can be represented in a framework; and how a synthesis of current knowledge of cities as socio-ecological systems helps to identify principles that can guide the designing of neighbourhood landscapes. Part 2 is more application focused, and is centred on neighbourhood landscape design guidelines inspired by the concept of ecosystem services. The guidelines consist of design approaches, practical strategies, design targets and performance monitoring indicators for tracking the performance of neighbourhood landscapes. The book is written for readers in academia and design practice, and anyone who has a role in shaping neighbourhood landscapes for the benefit of urban dwellers.
