This paper briefly reviews three conceptual frameworks: namely, the national agricultural research system (NARS), the agricultural knowledge and information system (AKIS) and the agricultural innovation system (AIS) concepts. Next, the paper reviews the definition of ‘innovation’ and proposes that agricultural innovation can occur at four different but interlinked domains.
Les populations africaines font partie des plus vulnérables face au changement climatique, du fait de leurs situations géographiques et économiques. Dans certaines régions du continent, où la variabilité climatique actuelle limite déjà la production agricole, le changement climatique pourrait l’inhiber complètement en l’absence de mesures pour adapter les systèmes agraires existants aux nouveaux contextes. Les paysans, qui représentent 70 à 80 % des agriculteurs en Afrique, seront très certainement les plus vulnérables face au changement climatique.
The frequency of natural disasters, especially storms and floods, has been increasing globally over the last several decades. Developing countries are especially vulnerable to such disasters but are often the least capable of coping with the associated impacts because of their limited adaptive capacity. Despite the increased interest in strengthening institutional capacity, it remains a challenge for many developing countries. Institutional capacity for disaster management and risk reduction can be built through various mechanisms.
