En el presente trabajo se presenta un estudio de la implementación del Fitomejoramiento Participativo en Cuba, una metodología sustentada sobre la base de la experiencia adquirida por un grupo de investigadores, agricultores y técnicos. La propuesta presenta en materiales y métodos las cuatro fases fundamentales de este proceso: 1) Diagnóstico, 2) Colección de recursos fitogenéticos, 3) Establecimientos de parcelas demostrativas y desarrollo de ferias de diversidad y 4) Experimentación campesina.
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.
In this paper, is described the market and social forces which influence the emergence of social innovations through various processes. The authors then look into the evolutionary pathways for social innovations , to avoid inertia and spur initiatives to bridge the social gap in an inclusive manner through mobilization of youth in particular. The ecosystem for social open innovations provides scope for connecting corporations
Visible and near-infrared diffuse reflectance spectroscopy (VIS-NIR) has shown levels of accuracy comparable to conventional laboratory methods for estimating soil properties. Soil chemical and physical properties have been predicted by reflectance spectroscopy successfully on subtropical and temperate soils, whereas soils from tropical agro-forest regions have received less attention, especially those from tropical rainforests. A spectral characterization provides a proficient pathway for soil characterization.
In developing regions with high levels of poverty and a dependence on climate sensitive agriculture, studies focusing on climate change adaptation, planning, and policy processes, have gained relative importance over the years. This study assesses the impact of farmer perceptions regarding climate change on the use of sustainable agricultural practices as an adaptation strategy in the Chinyanja Triangle, Southern Africa.
The study first identified fully efficient farmers and then estimated technical efficiency of inefficient farmers, identifying their determinants by applying a Zero Inefficiency Stochastic Frontier Model (ZISFM) on a sample of 300 rice farmers from central-northern Thailand. Next, the study developed scenarios of potential production increase and resource conservation if technical inefficiency was eliminated. Results revealed that 13% of the sampled farmers were fully efficient, thereby justifying the use of our approach.
Collaborative approaches are being promoted as inclusive forums for bringing state and non-state interests together to solve complex environmental problems. Networks have been recognized through previous research as important ways to involve stakeholders in such forums with members participating in knowledge creation and sharing as part of deliberative processes. Less well understood is the effectiveness of network creation and promotion by external actors, especially in relation to knowledge creation and sharing.
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.
This report provides summary findings and conclusions from a set of five case studies examining the scaling up of pro-poor agricultural innovations through commercial pathways in developing countries.
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.
