This study aimed at conducting a semi-participatory assessment of simple biomass carbonization techniques and available feedstocks and measured the agronomic benefits for urban vegetable farmers in Tamale, Ghana, where urban horticulture is an important component of the local economy. The paper objectives were firstly to evaluate the potential of on-farm biochar production from crop residues and secondly to investigate the relevance of this technology to farmers’ economic realities
This article examines the meaning, practices and potentials of ‘transformative agroecology learning’ as a collective strategy for food system transformation. Our study is based on our qualitative and action research with the European Coordination of Via Campesina to develop the European Agroecology Knowledge Exchange Network (EAKEN). This network is linked to the global network of La Via Campesina and builds on the strong experiences and traditions of popular education in Latin American peasant movements.
Recently, a new approach to extension and climate information services, namely Participatory Integrated Climate Services for Agriculture (PICSA) has been developed. PICSA makes use of historical climate records, participatory decision-making tools and forecasts to help farmers identify and better plan livelihood options that are suited to local climate features and farmers’ own circumstances.
Food sustainability transitions refer to transformation processes necessary to move towards sustainable food systems. Digitization is one of the most important ongoing transformation processes in global agriculture and food chains. The review paper explores the contribution of information and communication technologies (ICTs) to transition towards sustainability along the food chain (production, processing, distribution, consumption). A particular attention is devoted to precision agriculture as a food production model that integrates many ICTs.
The present study aims to characterize a new type of business ventures-agtech companies. Researchers conducted 3 interviews with the owners of agtechs located in Agtech valley and then by using a quantitative approach, collected secondary data of 74 firms from the Brazilian largest agricultural technology Science Park. This article contributes to the literature by characterizing the emerging type of new technology-based ventures within the agribusiness context.
El resultado de un análisis de la cadena de valor en el sector agrícola son insumos para formular y establecer políticas de desarrollo rural, más aún cuando la intermediación hace que el flujo de mercancías sea extenso y se producen sobre precios lo que resta competencia y valor a los productos agrícolas.
In this paper it is reviewed the literature on how transitions to sustainable food systems may play out and present a framework based on the Multi-Level Perspective on Socio-Technical Transitions, which builds upon conceptual developments from social and natural science disciplines.
Intermediary actors have been proposed as key catalysts that speed up change towards more sustainable socio-technical systems. Research on this topic has gradually gained traction since 2009, but has been complicated by the inconsistency regarding what intermediaries are in the context of such transitions and which activities they focus on, or should focus on. This study briefly elaborates on the conceptual foundations of the studies of intermediaries in transitions, and how intermediaries have been connected to different transition theories.
The shrimp sector has been one of the fastest growing agri-food systems in the last decades, but its growth has entailed negative social and environmental impacts. Sustainable intensification will require innovation in multiple elements of the shrimp production system and its value chain. The study focuses on the case of the shrimp sector in the Mekong Delta in Viet nam to explore the constraints inthe transition to sustainable intensification in shrimp farming, using an analytical framework based on innovation systems thinking, i.e., an aquaculture innovation systems framework.
Although an agro-based country, the farmers of Bangladesh do not receive significant returns from their products, due to some obstacles blocking the achievement of this ultimate goal. This study tries to identify the major challenges of the agroforestry product supply chains in Bangladesh, and offer an alternative solution through the involvement and experiences of farmer cooperatives within a Japanese cooperative model.
