La prise de conscience de l'importance des répercussions environnementales des activités agricoles ont généré une rupture du "statut d'exception" dont jouissaient les activités agricoles. De fait, les exploitants agricoles sont de plus en plus sollicités pour adopter des innovations environnementales, susceptibles d'atténuer les répercussions négatives et plus récemment de renforcer les fonctions positives (cf. les débats récents sur la multifonctionnalité).
Farmers in Asia like to grow cassava because the crop will tolerate long dry periods and poor soils, and will produce reasonable yields with little inputs. Most farmers realize, however, that cassava production on slopes can cause severe erosion, while production without fertilizer inputs may lead to a decline in soil productivity. Research has shown that cassava yields can be maintained for many years with adequate application of fertilizers, and that there are various ways to reduce erosion.
Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area.
Para preparación de este documento se llevó a cabo una consulta con los actores de la producción orgánica en las diferentes regiones del país, tratando de identificar desde su perspectiva, las limitaciones y potencialidades que presenta la actividad, así como las áreas estratégicas sobre las cuales se debe incidir para favorecer el desarrollo de la misma. El análisis de la información recabada permitió elaborar una propuesta de estrategia para el desarrollo de la actividad la cual, entre otros, contiene políticas y acciones alrededor de las mismas.
This report sets out the synthesis of work carried out within the framework of the Sahel and West Africa Club (SWAC) Secretariat Initiative on “The family economy and agricultural innovation: towards new partnerships”. The initiative aimed to stimulate analyses, collect field data and case studies that encourage debates between regional actors, with a view to informing the development of regional policies and actions in order to promote and strengthen producer access to agricultural innovation, where most producers are anchored in the family economy.
There are divergent views on what capacity development might mean in relation to agricultural biotechnology. The core of this debate is whether this should involve the development of human capital and research infrastructure, or whether it should encompass a wider range of activities which also include developing the capacity to use knowledge productively. This paper uses the innovation systems concept to shed light on this discussion, arguing that it is innovation capacity rather than science and technology capacity that has to be developed.
The objective of this paper is to: (a) review World Bank's pest management activities during 1999-2004; (b) assess those in view of the changes in the external and internal contexts; (c) identify appropriate opportunities of engagement on pest and pesticide issues; and (d) suggest means to further promote sound pest management in the World Bank operations. The importance of sound pest management for sustainable agricultural production is being recognized by many developing countries.

Biotechnology offers great potential to contribute to sustainable agricultural growth, food security and poverty alleviation in developing countries. Yet there are economic and institutional constraints at national and international levels that inhibit the poor people's access to appropriate biotechnological innovations.
The topics addressed in this book are of vital importance to the survival of humankind. Agricultural biodiversity, encompassing genetic diversity as well as human knowledge, is the base upon which agricultural production has been built, and protecting this resource is critical to ensuring the capacity of current and future generations to adapt to unforeseen challenges.
