Confrontés aux évolutions des enjeux et modèles de développement touchant les secteurs de l’agriculture et de l’alimentation, les organismes de recherche interrogent les méthodes d’évaluation des impacts liées aux activités de recherche. En effet les cadres méthodologiques conventionnels utilisés depuis les années 1950 ne répondent plus aux attentes sociétales et aux réalités de l’activité de recherche dans ce domaine.
De nombreux agriculteurs africains pratiquent des formes d'agriculture potentiellement qualifiables de "?biologiques?". Pourtant, la capacité de l'agriculture biologique à répondre aux enjeux de la sécurité alimentaire en Afrique est encore mal connue, car il existe peu de références expérimentales disponibles dans cette région. L'élicitation probabiliste est une méthode permettant de rendre compte de manière précise des connaissances d'experts sur une ou plusieurs quantités d'intérêt, et de décrire les niveaux d'incertitude associés.
La agricultura familiar de los países del Sur constituye uno de los sectores más directamente afectados y amenazados por los cambios climáticos. La cuestión de la adaptación, y en particular, la de la adaptación de la agricultura, ha ido ganando terreno en el transcurso de la última década en las agendas políticas nacionales e internacionales.
El informe está estructurado en tres partes:
• la primera parte trata de la adaptación de la agricultura familiar a los cambios climáticos y de las condiciones de la adaptación; • la segunda parte aborda el lugar que ocupa la adaptación de la agricultura familiar en las políticas públicas;
• la tercera parte propone algunas recomendaciones para una mejor integración de este tema en las políticas públicas.
Una presentación de los tres estudios de caso-países figura también en anexo.
The main goal of the study is to quantify the effects of a) change in nitrogen fertilization rate, b) adjustment of sowing date, c) implementation of new cultivars, and d) supplementary irrigation on maize cropping systems across six African countries including Ghana, Nigeria, Kenya, Malawi, Ethiopia and Burkina Faso. For this purpose, 30 years (1980-2010) of climate data are used as well as soil and management information obtained from global datasets at 0.5° x 0.5° spatial resolution.
Xanthomonas Wilt of Banana (BXW) is a complex problem in the African Great Lakes Region that is affecting the livelihoods of millions of smallholder farmers. Since the first disease reports from Uganda and the Democratic Republic of Congo in 2001, BXW has been studied widely. The majority of these studies focus on the technological or biophysical dimensions, while aspects and influence of socio-cultural, economic and institutional dimensions only recently started to gain attention.
The aim of this study was to investigate the vulnerabilities of women involved in a bean value chain development intervention at the Maendeloe Innovation Platform in Eastern DRC. Specifically, the paper first discusses the roles of women and men in the value chain, what production resources and benefits they access and control, the role of the IP as a vehicle for women’s empowerment, and identifies women’s gender needs. Secondly, the paper identifies women’s vulnerabilities, and the capacities that the IP could build on, to support their participation in bean value chain development
This brief discusses the emergence of Asia as a hotpot of innovation and the implications for Australia's own innovation capacity
The term ‘systemic innovation’ is increasing in use. However, there is no consensus on its meaning: four different ways of using the term can be identified in the literature. Most people simply define it as a type of innovation where value can only be derived when the innovation is synergistically integrated with other complementary innovations, going beyond the boundaries of a single organization. Therefore, the term ‘systemic’ refers to the existence of a co-ordinated innovation system.
What are key characteristics of rural innovators? How are their experiences similar for women and men, and how are they different? To examine these questions, this study draw on individual interviews with 336 rural women and men known in their communities for trying out new things in agriculture. The data form part of 84 GENNOVATE community case studies from 19 countries. Building on study participants’ own reflections and experiences with innovation in their agricultural livelihoods, we combine variable-oriented analysis and analysis of specific individuals’ lived experience.
