L’une des avancées les plus importantes dans le domaine de l’observation de la terre est la découverte des indices spectraux, ils ont notamment prouvé leur efficacité dans la caractérisation des surfaces agricoles, mais ils sont généralement définis de manière empirique. Cette étude basée sur l’intelligence artificielle et le traitement du signal, propose une méthode pour trouver un indice optimal. Et porte sur l’analyse d’images issues d’une caméra multi-spectrale, utilisée dans un contexte agricole pour l’acquisition en champ proche de végétation.
This paper addresses how co-producing knowledge can assist local farmers in reshaping their territories into sustainable farming systems. We describe the emergence and consolidation of an agroforestry system in an Eastern Amazon forest frontier, unpacking the co-production of a new farming system over recent decades. Instead of assuming pre-defined categories (e.g., traditional/technical, local/external), the analysis focuses on interactions among knowledge holders and how multiple knowledge sources are intercalated.
The future of inclusive forestry in Nepal depends on forestry professionals who can recognise patriarchal roots of gender injustice as they operate in the ideologies and apparatus of forest governance, and who can resist those injustices through their work. This paper uses the notion of knowledge practices to explore the recognition of injustice amongst Nepal’s community forestry professionals, and the relationship between recognition and resistance, highlighting the inherently political nature of all knowledge practices.
L’érosion hydrique est une préoccupation agronomique, économique et environnementale importante en milieu semi-aride méditerranéen. Le choix de la méthode pour l’estimer dépend des données disponibles et des conditions de la zone d’étude. Cet article vise à quantifier et spatialiser l’érosion hydrique en utilisant l’équation universelle des pertes en sol (Universal Soil Loss Equation [USLE]) dans ses versions modifiée (Modified − MUSLE) et révisée (Revised − RUSLE) et couplées à un Système d’information géographique (SIG) : MUSLE-SIG et RUSLE-SIG.
This paper contends that the exclusion of millions of poor from agricultural development gains is inexorably linked to the innovation system features that have evolved over time. An oft repeated lament of the Government of India about the inadequacy of reforms in agricultural research and extension, is used to explore the structure and institutions of agricultural innovation. Three main components of the agricultural innovation system, are the agricultural research and extension actors, the farming communities, and policy making agencies.
Good governance of community fish refuge-rice field fishery (CFR-RFF) systems, which are a vital source of nutritious aquatic foods, is integral to the food and nutrition security of rural households in Cambodia. Intentional integration of nutrition and gender activities into CFR management has the potential to further bolster these outcomes. Using qualitative and quantitative data, we aimed to document the impacts of the nutrition and gender activities conducted alongside CFR management activities.
Animal-source foods (ASF), such as fish, provide a critical source of nutrients for dietary quality and optimal growth of children. In sub-Saharan Africa, children often consume monotonous cereal-based diets, a key determinate of malnutrition such as stunting. Identifying existing sources of ASF for children’s diets will inform the development of nutritious food systems for vulnerable groups.
The project Empowering Women Fish Retailers (EWFIRE) Project. Funded by the European Commission (EuropeAid), the project supports vulnerable women retailers and processors to develop their businesses in five urban areas across the Sharkia governorate, lower Egypt (Zagazig, Faous, Belbeis, Al-Hussainyaand Abu-Kebeer).
1. Many coastal communities depend on ecosystems for goods and services that contribute to human well-being. As long-standing interactions between people and nature are modified by global environmental change, dynamic and diversified livelihood strategies that enable seasonal adaptation will be critical for vulnerable coastal communities. However, the success of such strategies depends on a range of poorly understood influences. 2.
Fish is a key source of income, food, and nutrition in Zambia, although unlike in the past, capture fisheries no longer meet the national demand for fish. Supply shortfalls created an opportunity to develop the aquaculture sector in Zambia, which is now one of the largest producers of farmed fish (Tilapia spp.) on the continent. In its present form, the aquaculture sector exhibits a dichotomy.
