El presente trabajo tuvo como objetivo mostrar las experiencias en el cultivo del arroz en el mundo, así como de varias regiones de Cuba, donde las ferias de diversidad constituyeron la mejor forma de dar acceso rápido y eficiente a las variedades, con la participación de los productores de arroz no especializado. El fitomejoramiento participativo (FP) es un enfoque relativamente nuevo para el desarrollo del germoplasma, que incluye el mejoramiento de plantas y la selección varietal participativa (SVP).
Agriculture plays an important role in the economy of Pakistan and it is not possible to realize sustainable biological yields without following sustainable agricultural extension. However, these extension activities are not making significant impacts on crop yields and have not been able to help farmers realize sustainable biological yields and elevated rural livelihoods. The purpose of this study is to ascertain the perceptions of the farmers about the extension services. A survey study was conducted in the Peshawar district of Khyber Pakhtunkhwa (KP) province - Northern Pakistan.
This study, evaluates the intervening influence of extension services on livelihood impacts of drought tolerant maize adoption and the potential mechanisms through which extension can enhance or reduce impact of drought tolerant maize using cross-sectional household level data from smallholder maize producers in Zimbabwe. Specifically, we examine whether access to agriculture extension services influences the relationship between livelihood outcomes and the adoption of drought-tolerant maize varieties in selected districts in the country
Using a mixed methods approach, this study gathered the views of farmers, farm advisors, and industry representatives about integrated farm management in England and Wales, and interpreted these through a theoretical framework to judge the strength of the concept. Overall, the general principles of Integrated Farm Management were found to be coherent and familiar to most of our respondents. However, the concept performed poorly in terms of its resonance, simplicity of message, differentiation from other similar terms and theoretical utility.
This article analyzes the politics of localizing food systems at play in the FPCs of Ghent (Belgium) and Philadelphia (Pennsylvania, USA). The focus is on the development of urban agriculture in both cities, and includes an analysis of the politics of scale through three scalar practices of scale framing, scale negotiating, and scale matching. This analysis reveals that differences in the way in which the politics of scale are played out in both FPCs resulted in the creation of different opportunities and constraints for urban agriculture development
Local extension agents can benefit from the simple procedures in developing irrigation calendars for other irrigated crops. This study gives important lesson for local and regional decision makers, on their endeavour to increase the productivity of small scale irrigated agriculture. This paper is organized as follows: Section 2 describes the study area, practical irrigation schedule development method, alternative irrigation schedules and data collection and analysis methods. Section 3 presents the results.
The aim of this paper is to propose an innovative operational framework that couples life cycle assessment (LCA) and a participatory approach to overcome these issues. The first step was to conduct a progressive participatory diagnosis of the socio-ecological structure of the rural territory and to characterise the main cropping systems. The results of the diagnosis and other data were progressively triangulated, validated and consolidated with the stakeholders at the territorial level. The paper discusses the quality and validity of data obtained using a participatory approach.
The purpose of this study is to develop a robust, rigorous and replicable methodology that is flexible to data limitations and spatially prioritizes the vulnerability of agriculture and rural livelihoods to climate change. The methodology was applied in Vietnam, Uganda and Nicaragua, three contrasting developing countries that are particularly threatened by climate change. We conceptualize vulnerability to climate change following the widely adopted combination of sensitivity, exposure and adaptive capacity.
The tank-based irrigated agricultural system in the Dry Zone of Sri Lanka is one of the oldest historically evolved agricultural systems in the world. The main component of the system consists of a connected series of man-made tanks constructed in shallow valleys to store, convey and utilize water for paddy cultivation. Up to 10,000 tanks originating from the heydays of ancient kingdoms are still integrated in the current agricultural landscape. During the last two millennia, this indigenous system has undergone many changes in technological, management and socio-cultural norms.
Innovative approaches are needed to shift towards more sustainable, equitable and healthy agri-food systems. Building on the increasing recognition of the relevance of traditional agroecological knowledge (TAeK) in sustainable food systems, this paper aims to describe innovative agri-food initiatives and explore how the use and valorization of TAeK may transform conventional agri-food systems. It employs a case-study approach in Spain, where we conducted semi-structured interviews with 12 representatives of alternative agri-food initiatives.
