Agricultural investments made by developing countries and multilateral development banks (MDBs) have declined in recent decades. This decline is associated with a slowdown in the growth of agriculture productivity. Most development institutions have recognized the damage caused by this past neglect, in part evident in rising food prices, and renewed attention to agriculture and agribusiness is emerging. But this renewed interest will need to deliver results, especially in Sub-Saharan Africa, where the MDBs have had the least success but where the needs and opportunities are enormous.
The objective of this report is to identify and evaluate best practices in smallholder private irrigation in West Africa. The report is based on a comparative assessment of the smallholder private irrigation subsector in Burkina Faso, Mali, Niger, and Nigeria, which included a literature review, field visits, and workshops at both national and regional levels. The task lists for the assessment is provided in annex one. This report first presents the main features of smallholder irrigation and the development projects that have promoted its use in West Africa in chapter two.
Growing local and informal markets in Asia and Africa provide both challenges and opportunities for small holders. In developing countries, market failures often lead to suboptimal performance of the value chains and limited and inequitable participation of the poor. In recent years, innovation platforms have been promoted as mechanisms to stimulate and support multistakeholder collaboration in the context of research for development. They are recognized as having the potential to link value chain actors, and enhance communication and collaboration to overcome market failures.
The presentation was given in January 2009 and introduced why a new approach for livestock development for poverty alleviation was desirable, innovation, innovation systems and value chains, building of innovation platforms, learning-oriented monitoring and evaluation, and scaling up and out.
The development of effective agricultural monitoring networks is essential to track, anticipate and manage changes in the social, economic and environmental aspects of agriculture. The authors welcome the perspective of Lindenmayer and Likens (J. Environ. Monit., 2011, 13, 1559) as published in the Journal of Environmental Monitoring on their earlier paper, “Monitoring the World's Agriculture” (Sachs et al., Nature, 2010, 466, 558–560).
This assessment has been conducted over December 2015 to May 2016 under the Powering Agriculture Support Task Order (PASTO). PASTO is funded by USAID and implemented by Tetra Tech ES, Inc. PASTO provides support services to the Powering Agriculture: An Energy Grand Challenge for Development (PAEGC) and its Founding Partners to enable their effective management, monitoring and evaluation of the program.
One of the most important challenges for the researchers in the 21st Century is related to global heating and climate change that can have as consequence the intensification of natural hazards. Another problem of changes in the Earth's climate is its impact in the agriculture production. In this scenario, application of statistical models as well as development of new methods become very important to aid in the analyses of climate from ground-based stations and outputs of forecasting models. Additionally, remote sensing images have been used to improve the monitoring of crop yields.
L'innovation est souvent présentée comme l'un des principaux leviers pour promouvoir un développement plus durable et plus inclusif. Dans les domaines de l'agriculture et de l'alimentation, l'innovation est marquée par des spécificités liées à sa relation à la nature, mais aussi à la grande diversité d'acteurs concernés, depuis les agriculteurs jusqu'aux consommateurs, en passant par les services de recherche et de développement.
L’évaluation participative repose sur le principe d’une participation active des principales parties prenantes (dont les groupes les moins organisés) à l’exercice d’évaluation. Cette démarche présente un certain nombre d’atouts qui peuvent se transformer en limites quasi rédhibitoires si certains préalables ne sont pas remplis. La finalité de cet article est de discuter des avantages et des inconvénients de la participation, ainsi que des conditions à réunir pour que l’évaluation participative puisse atteindre ses objectifs.
Les enjeux liés au changement climatique et à la sécurité alimentaire confortent la nécessité de mettre au point des démarches de conception/évaluation de systèmes durables, qu’il s’agisse d’améliorer les situations existantes ou d’imaginer de nouvelles voies de développement. En régions chaudes, l’élevage remplit aussi des fonctions non productives et doit s’adapter aux aléas et incertitudes.
