Les grandes exploitations agricoles créées dans le cadre de la loi de mise en valeur agricole de 1983 dans le Sahara algérien étaient vouées à une production céréalière sous pivot. L’objectif était de développer économiquement des régions sahariennes pour partie marginalisées, ainsi que de réduire la dépendance chronique en céréales du pays. L’État a considérablement investi pour équiper ces exploitations agricoles dans le cadre d’un vaste plan de développement rural. Mais trente ans après la parution de la loi, les réalisations demeurent limitées au regard des objectifs initiaux.
CONTEXT
Big data applications in agriculture evolve fast, as more experience, applications, good practices and computational power become available. Actual solutions to real-life problems are scarce. What characterizes the adoption of big data problems to solutions and to what extent is there a match between them?
OBJECTIVE
We aim to assess the conditions of the adoption of big data technologies in agricultural applications, based on the investigation of twelve real-life practical use cases in the precision agriculture and livestock domain.
METHODS
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.
Well-designed and supported innovation niches may facilitate transitions towards sustainable agricultural futures, which may follow different approaches and paradigms such as agroecology, local place-based food systems, vertical farming, bioeconomy, urban agriculture, and smart farming or digital farming.
This study has been produced with the overall goal to document and analyse exisiting best practices in the field of RWHI management in sub-Saharan Africa, with a special focus on Ethiopia, Kenya, Mozambique and Zimbabwe. This is meant to determine the suitability of RWHI management under multivariate biophysical and socioeconomic conditions. The best practices include specific information and know-how on the performance, cost-efficiency and impacts of RWHI technologies.
Improvements in the sustainability of agricultural production depend essentially on advances in the efficient use of nitrogen. Precision farming promises solutions in this respect. Variable rate technologies allow the right quantities of fertilizer to be applied at the right place. This helps to both maintain yields and avoid nitrogen losses. However, these technologies are still not widely adopted, especially in small-scale farming systems. Recent developments in sensing technologies, like drones or satellites, open up new opportunities for variable rate technologies.
El Programa de Innovación Agropecuaria Local (PIAL) posee una amplia diseminación de acciones en cientos de fincas, buscando alternativas locales que le den solución a las necesidades de prácticas sostenibles con carácter agroecológico, para ello se hace necesario demostrar la efectividad económica del desarrollo a nivel de finca. Este artículo desarrolo un análisis de costo-beneficio que es una herramienta de toma de decisiones para desarrollar sistemáticamente información útil acerca de los efectos deseables e indispensables.
Katalyst project has been facilitating awareness raising on the importance of balanced fertiliser application in Bangladesh since 2006.
The promotion of land, soil and water conservation measures has been a widespread development in sub-Saharan Africa in a bid to tackle degradation and improve productivity. As a result, several governments have launched various campaigns on soil, land and water conservation measures. The aim of this study is to determine some of the factors that influence farmers’ awareness (knowledge) and adoption of land, soil and water conservation practices. Data for this study was collected from 312 households using a questionnaire survey in the Chinyanja Triangle of Southern Africa.
