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 presentation for the Third Global Conference on Agricultural Research for Development (GCARD3,Johannesburg, South Africa, 5-8 April 2016) illustrates the topic of competitiveness in Africa smallholders system, focusing on the Integrated Agricultural Research for Development (IAR4D) and Agricultural Innovation Systems (AIS) concepts and on the role of the innovation platforms.
Dans le besoin urgent de lutter contre le changement climatique, une priorité essentielle est de renforcer la capacité de ces groupes et communautés les plus vulnérables, et déjà fortement affectés, à améliorer leur capacité à adapter leurs systèmes de subsistance.
Innovation processes in rural contexts occur in systems that are diverse, coupled with complex challenges. Dealing with complex systems requires an understanding of the social dynamics of actor networks and innovation.This study attempted to provide insights on thecompositional dynamics of actor networks,and how they influenceinteractive learning and innovation among agro-processing enterprises in South Africa. The guiding research questions to help address the study objectives are:What are the structural characteristics of actor networks for innovation in rural contexts?
The study explored the contribution of information and communication technology (ICT)-based information sources to market participation among smallholder livestock farmers. Use of ICTs is considered paramount for providing smallholder farmers with required market information, and also to reduce market asymmetries. A double hurdle regression was utilized to analyze data collected from 150 smallholder livestock farmers in the study area.
These advanced training materials have been produced to foster the capacity of practitioners from private, nongovernmental and public sectors on one hand, and academics and scientists on the other, to practically implement cost-efficient RWHI technologies and practices in arid and semi-arid areas. Therefore, these training materials intend to provide the required information to support proper planning, design and construction of cost-efficient RWHI technologies and practices, with special emphasis on the specific problems encountered in Ethiopia, Kenya, Mozambique and Zimbabwe.
El modelo de Agencias de Gestión de la Innovación para el Desarrollo de Proveedores (AGI-DP) se diseñó e implementó con extensionistas rurales desde el año 2009 y hasta el 2014. Permite llevar a la práctica la selección, capacitación, desarrollo, seguimiento y evaluación de equipos técnicos especializados en extensionismo en red.
Este documento es el resultado de los trabajos y deliberaciones del Panel Independiente sobre la Agricultura para el Desarrollo de América Latina (PIADAL). Este libro busca sistemtizar los procesos políticos y construir mejores acuerdos y propuestas si los problemas que deben superarse han sido analizados técnicamente y las posibles soluciones, sus costos y sus consecuencias están disponibles al momento de tomar las decisiones políticas.
Agricultural Extension Reforms in South Asia: Status, Challenges, and Policy Options is based on agricultural extension reforms across five South Asian countries, reflecting past experiences, case studies and experiments. Beginning with an overview of historical trends and recent developments, the book then delves into country-wise reform trajectories and presents several cases testing the effectiveness of different types (public and private) and forms (nutrition extension, livestock extension) of extension systems.
This chapter examines the current state of agricultural extension reforms and their linkages to the agricultural research system reforms in India and identifies the policy options and strategic priorities for making it relevant, responsive, and efficient. It explores how the National Agriculture Research Systems (NARS) responded with its own set of reforms that were sought to increase its relevance and its linkages to the extension system reforms.
