El presente artículo describe los resultados de diseminación participativa de semillas (DPS) en términos productivos, ambientales y socioeconómicos en Cuba y México. El concepto de diseminación participativa de semillas (DPS) surgió en Cuba a partir de la integración de las ferias de diversidad de semillas con la experimentación y diseminación de semillas por los campesinos. Una feria de diversidad de semillas es un método donde los fitomejoradores, productores y agentes extensionistas tienen acceso a la diversidad en uno o más cultivos.
El objetivo de la investigación fue analizar cómo se ha beneficiado el ecosistema agrícola del municipio con la introducción de diversidad. Se calcularon los índices de diversidad específica de Margalef y riqueza específica de Shannon-Weiner y se consideraron tres etapas: antes de FP, después de FP y puesta en acción del Programa de Innovación Agrícola Local (PIAL). Se realizó un levantamiento de especies y variedades en 17 fincas de productores del municipio La Palma, en las zonas donde ha intervenido el proyecto Fitomejoramiento Participativo (FP)
Este artículo presenta una propuesta de marco teórico, conceptual y operativo (MaTCo) diseñado para documentar las experiencias de dichos actores y las estrategias de innovación tecnológica implementadas en el Nodo de Innovación (HUB) Trópico Bajo de Chiapas. Dicho marco incluye indicadores para conocer los principios, metodologías y herramientas utilizadas por cada actor estudiado. Para ello fue necesario construir e implementar el MaTCo, desde una perspectiva socio-agronómica holística y aplicarlo a cuatro estudios de caso de actores que colaboran con el programa.
Conflicts of interests have been hypothesized when agricultural advisory services are connected to agri-input businesses. However, these have not been examined using large sets of advisory service and grower data. We provide quantitative insights into dependencies between service, crop production, sustainability and the level of agri-input business-linkage of extension workers. This study analyzed 34,000+ prescription forms (recommendations) issued to growers in China, as well as grower interview data.
There is a blossoming of voluntary certification initiatives for sustainable agro-food products and production processes. With these certification initiatives come traceability in supply chains, to guarantee the sustainability of the products consumed. No systematic analysis exists of traceability systems for sustainability in agro-food supply chains.
In recent years, the international status of agriculture in the BRICS countries—Brazil, Russia, India, China and South Africa—has been continuously improved. In 2018, the gross agricultural production of the BRICS countries accounted for more than 50% of the world’s total. Further strengthening the developing cooperation of the BRICS countries is of great significance for ensuring global food security.
Boundary-spanning search for knowledge is an effective way for enterprises to acquire heterogeneous knowledge, and is also an important pre-stage to realize effective knowledge reconstruction. Based on the boundary-spanning search for knowledge theory, this paper studies the relationship between boundary-spanning search for knowledge and the sustainable innovation ability of agricultural enterprises considering the influence of organizational knowledge reconstruction, from a Chinese perspective.
The impact of global warming on crop growth periods and yields has been evaluated by using crop models, which need to provide various kinds of input datasets and estimate numerous parameters before simulation. Direct studies on the changes of climatic factors on the observed crop growth and yield could provide a more simple and intuitive way for assessing the impact of climate change on crop production.
Addressing complex environmental problems requires the collaboration of stakeholders with divergent perspectives, a goal that is challenged by diverse factors. Challenges hindering multi-stakeholder collaboration (MSC) for sustainability have previously been addressed in the context of transnational partnerships. However, less is known regarding how place-based MSC operates, especially in the context of the Global South.
The last decade has seen an increasing advancement and interest in the integration of agroecology and participatory action research (PAR). This article aims to: (1) analyze the key characteristics and principles of two case studies that integrated PAR and agroecology in Central America; and (2) learn from the lessons offered by these case studies, as well as others from the literature, on how to better integrate PAR and agroecology.
