The determination of bunch features that are relevant for bunch weight estimation is an important step in automatic vineyard yield estimation using image analysis. The conversion of 2D image features into mass can be highly dependent on grapevine cultivar, as the bunch morphology varies greatly. This paper aims to explore the relationships between bunch weight and bunch features obtained from image analysis considering a multicultivar approach.
This paper presents findings of an explorative case study that looked at 22 organisations identified as fulfilling an intermediary role in the Kenyan agricultural sector. The results show that these organisations fulfill functions that are not limited to distribution of knowledge and putting it into use. The functions also include fostering integration and interaction among the diverse actors engaged in innovation networks and working on technological, organisational and institutional innovation.
This paper examines how the different institutional innovations arising from various permutations of linkages and interactions of ARD organizations (national, international advanced agricultural research centres and universities) influenced the different outcomes in addressing identified ARD problems.
Linking farmers to markets is widely viewed as a milestone towards promoting economic growth and poverty reduction. However, market and institutional imperfections along the supply chain thwart perfect vertical and spatial price transmission and prevent farmers and market actors from getting access to information, identifying business opportunities and allocating their resources efficiently. This acts as a barrier to market-led rural development and poverty reduction.
The report builds on the 'towards a vision for agricultural innovation in Chile in 2030' report and is further based on a series of background papers and a consultation process that took place between December 2010 and May 2011. The current study is the third in a series of three that were agreed between the Government of Chile and the World Bank to support the development of a long-term agricultural innovation strategy. The first paper reviewed the functioning of the three main public technological institutes and recommended how their performance can be improved.
This paper aims to develop a vision statement for the agricultural sector that may then guide the future investments in Chile's agricultural innovation system, A joint and shared perspective on how the sector might look and what role agricultural innovation should play in getting there is a prerequisite for any effective strategy. But developing such a vision is not only a function of what the country wants: it also depends on the context in which Chile's agricultural sector will find itself.
In order for agricultural development to fulfill its potential role as a source of growth and reducer of poverty, it must be constantly renewed through knowledge and innovation. Getting resources into the hands of innovators and providing incentives for producers, agricultural service providers, and entrepreneurs to collaborate in developing and applying new methods and technologies is a priority among institutions concerned with agricultural knowledge.
Dans cet article, à travers l’étude du cas de la filière forêt-bois-papier aquitaine, nous soulignons la nécessité d’intégrer une plus forte prise en compte des ressources naturelles dans les analyses en termes de systèmes d’innovation. Prenant appui sur la principale spécificité de cette filière, à savoir sa forte dépendance à la ressource ligneuse, le présent article est focalisé sur la manière dont cette dépendance configure le système.
il est possible et nécessaire aujourd’hui d’opérer un bilan du développement durable (DD) en s’appuyant sur les formes concrètes qu’il a prises depuis plus de vingt ans. Malgré les discussions, interrogations ou critiques que le terme a suscitées, il est sans conteste, depuis la conférence de Rio en 1992, l’horizon normatif des projets, programmes et politiques d’aide publique au développement qui opèrent concrètement sur les territoires, et il accompagne maintenant les stratégies d’entreprise.
Les investissements dans les agrocarburants en Afrique constituent une véritable question de développement. Ils sont pleinement concernés par le débat sur les acquisitions de terres à grande échelle et exposent les populations et les agricultures africaines à plusieurs types de risques. Dans le même temps, ils représentent une opportunité dans des pays où l’accès à l’énergie est sans doute un des principaux facteurs de blocage au développement. Certaines formes d’investissement peuvent être encouragées, à condition qu’elles profitent aux économies locales.
