Crop surface models (CSMs) representing plant height above ground level are a useful tool for monitoring in-field crop growth variability and enabling precision agriculture applications. A semiautomated system for generating CSMs was implemented. It combines an Android application running on a set of smart cameras for image acquisition and transmission and a set of Python scripts automating the structure-from-motion (SfM) software package Agisoft Photoscan and ArcGIS. Only ground-control-point (GCP) marking was performed manually.
Given the search for new solutions to better prepare cities for the future, in recent years, urban agriculture (UA) has gained in relevance. Within the context of UA, innovative organizational and technical approaches are generated and tested. They can be understood as novelties that begin a potential innovation process. This empirical study is based on 17 qualitative interviews in the U.S. (NYC; Philadelphia, PA, USA; Chicago, IL, USA).
This paper aims to develop a vision statement for the agricultural sector that may then guide the future investments in Chile's agricultural innovation system, A joint and shared perspective on how the sector might look and what role agricultural innovation should play in getting there is a prerequisite for any effective strategy. But developing such a vision is not only a function of what the country wants: it also depends on the context in which Chile's agricultural sector will find itself.
This paper discusses the challenges and determinants of agro-operations and innovation initiatives in developing countries. With particular reference to the Caribbean region, available country statistics and data are analysed. A generic model of collaborative innovation for agriculture that stresses collaboration among the stakeholders (government, knowledge institutions, public and private firms and others) is described.
Sorghum crop is grown under tropical and temperate latitudes for several purposes including production of health promoting food from the kernel and forage and biofuels from aboveground biomass. One of the concerns of policy-makers and sorghum growers is to cost-effectively predict biomass yields early during the cropping season to improve biomass and biofuel management. The objective of this study was to investigate if Sentinel-2 satellite images could be used to predict within-season biomass sorghum yields in the Mediterranean region.
A partir de experiencias de investigación-transformación en sistemas agrícolas en Cuba, el trabajo examina áreas relevantes en una concepción de desarrollo rural sustentable, como el fortalecimiento y la diversificación de los sistemas agropecuarios y las economías locales, la articulación de actores y participación en los procesos de desarrollo, que evidencian el movimiento desde un enfoque eminentemente tecnológico hacia una propuesta más social e integradora
The interactions between bottom-up initiatives and top-down structures in the implementation of regional development policies and projects are complex in theoretical and practical terms. Using concepts such as transformative social innovation, adaptive governance, and bridging institutions, we developed an analytical framework to enhance understanding of the processes by which local top-down and bottom-up forces enhance sustainable rural development by co-developing bottom-linked governance.
Aujourd’hui, l’agriculture familiale fait preuve de dynamisme. Pour prouver qu’elle est un modèle à défendre, il faut convaincre les États de mener des politiques volontaristes et souveraines de rénovation de l’agriculture. Une politique efficace devra identifier les forces et les faiblesses de l’agriculture familiale, lutter contre l’accaparement des terres, encourager les jeunes paysans et les paysannes. Prendre en compte les différentes dimensions de l’agriculture familiale est nécessaire pour mener à une transformation efficace.
Drawing on studies from Africa, Asia and South America, this book provides empirical evidence and conceptual explorations of the gendered dimensions of food security. It investigates how food security and gender inequity are conceptualized within interventions, assesses the impacts and outcomes of gender-responsive programs on food security and gender equity, and addresses diverse approaches to gender research and practice that range from descriptive and analytical to strategic and transformative.
Despite the rapid international development of biotechnology, we still lack knowledge and information about how low- and middle-income countries can best access this promising technology. Nor are the socioeconomic repercussions of applying biotechnology in these countries’ agricultural sectors well understood. This study seeks to fill in some of the gaps in our knowledge by analyzing a biotechnology transfer project that provided proprietary recombinant potato technology to Mexico.
