African farming systems are highly heterogeneous: between agroecological and socioeconomic environments, in the wide variability in farmers’ resource endowments and in farm management. This means that single solutions (or ‘silver bullets’) for improving farm productivity do not exist. Yet to date few approaches to understand constraints and explore options for change have tackled the bewildering complexity of African farming systems. In this paper we describe the Nutrient Use in Animal and Cropping systems – Efficiencies and Scales (NUANCES) framework.
The purpose of this article is to investigate effective reformism: strategies that innovation networks deploy to create changes in their environment in order to establish a more conducive context for the realization and durable embedding of their innovation projects. Using a case study approach, effective reformism efforts are analyzed in a technological innovation trajectory related to the implementation of a new poultry husbandry system and an organizational innovation trajectory concerning new ways of co-operation among individual farms to establish economies of scale.
This is the third volume of the proceedings of the national conference on "Water for Food and Environment", which was held from June 9 -11, 2009 at the Bandaranaike Memorial International Conference Hall (BMICH). The volumes 1 and 2 have been produced as separate documents of this report series. In response to a call for abstracts, 81 abstracts were received from government institutes dealing with water resources and agriculture development, universities, other freelance researchers and researchers from the International Water Management Institute (IWMI).
The purpose of this issues paper is to provide an overview of the issues, numbers, disputes, and approaches so that contributors to SOW11 can share a common framework and consider how the innovations they describe fit into the larger international discourse. The paper is structured as follows: • Section 2 describes diverse perspectives on food security that emphasize global supply chains to feed middle-class populations in cities; smallholder farmers who still supply much of the world; and smallholder farmers who are relatively disengaged in commercial markets.
Although much has been written about climate change and poverty as distinct and complex problems, the link between them has received little attention. Understanding this link is vital for the formulation of effective policy responses to climate change. This paper focuses on agriculture as a primary means by which the impacts of climate change are transmitted to the poor, and as a sector at the forefront of climate change mitigation efforts in developing countries.
Livelihoods, food security, and development processes in Sub-Saharan Africa are highly dependent on land management practices to generate natural ecosystem goods and services. Out of a total population of about 717 million people, almost 60 percent depend for their livelihood on agriculture, hunting, fishing, or forestry. However, unsustainable land management already is leading to large-scale land degradation trends, which pose a threat to food security and poverty alleviation in Sub-Saharan Africa. Climate change threatens to exacerbate and add to the existing vulnerabilities.
The World Bank has a long relationship with Uruguay's agricultural sector, expanding over a period of more than 60 years in which several projects and various analytical and advisory assistance initiatives have been implemented.
Impératif de développement et impératif de lutte contre le changement climatique sont plus que jamais liés. Le changement climatique accentue les inégalités en touchant de plein fouet les populations les plus pauvres. En accentuant la vulnérabilité de ces pays, il compromet chaque jour un peu plus leurs chances de se développer. C’est pourquoi, depuis 2007, Coordination SUD1 et le RAC-France ont décidé d’unir leurs forces pour peser davantage sur la position de la France dans le cadre des négociations internationales sur le climat.
En 2006, un rapport de la FAO pointait du doigt l’élevage comme l’un des principaux responsables du réchauffement climatique. Si la viande semble donc bien sur le gril, faut-il pour autant tous devenir végétariens ? Dans les pays du Sud, l’élevage a une grande importance socio-économique. L’élevage est la ressource principale pour plus d’un milliard de paysans pauvres. C’est essentiellement le Nord, avec en moyenne 80kg de viande consommée par habitant et par an, qui contribue aux 18 % d’émissions de gaz à effet de serre dues à l’élevage.
L’Assemblée générale des Nations unies a annoncé que 2010 est l’Année internationale de la biodiversité. Alors que l’humanité commence seulement à tenter de résoudre les dégâts provoqués par le réchauffement climatique, la perte de la biodiversité engendrée par les activités humaines est encore plus destructrice pour la planète ! Pour les populations rurales et les paysans du Sud, la préservation de la biodiversité est vitale. Comme le dit Patrick Ten Brink, directeur de l’Institut européen des politiques environnementales : » Les écosystèmes sont le PIB des pauvres en milieu rural ».
