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.
This paper discusses external influences on innovation platforms (IPs) and the options for effective responses. The platforms examined in this paper were conceived as vehicles for facilitating institutional change in support of innovation that benefits smallholders, in selected agro-enterprise domains in Benin, Ghana and Mali. They were designed and implemented in a manner that enabled experimentation with processes of change in the selected domains.
The evolution of mobile phone applications has opened up a platform for easy and real time dissemination and exchange of agricultural information among agricultural extension officers, farmers, agricultural institutions and non-governmental institutions. This study examined attitude, knowledge and constraint associated with the use of mobile phone apps by farmers in North West region of Nigeria. A descriptive survey design was adopted; data collection tool was pre-tested and administered as interview schedule to randomly sampled farmers.
In the Office du Niger large rice farming irrigation scheme in Mali, water management has been a permanent source of tension between the smallholder tenants and the administration. The transfer of tertiary canal maintenance to the tenant farmers was expected to improve water management but, in practice, that rather led to deterioration.
Responding to global food crisis, such as imposed by climate change, requires resilient food systems that are able to respond to shocks. Resilience thinking, as an approach to agriculture development, focuses on enhancing the capacity of both the human and ecological systems inter alia. In this paper, the concept of resilience is approached from the perspective of socio-ecological systems dynamics. In particular, the study examined the contribution of farmers to research towards enhanced resilience of traditional African vegetable production systems in northern Ghana.
This article presents a different dimension of the innovation systems approach, going beyond analysis and shedding light on how these processes can be facilitated in practice. This is based on 20 years' experience with innovations systems. The focus is on the role of facilitation in triggering the changes, as well as in integrating learning and knowledge management (KM) in the innovation process.
One option for practically applying innovation systems thinking involves the establishment of innovation platforms (IPs). Such platforms are designed to bring together a variety of different stakeholders to exchange knowledge and resources and take action to solve common problems. Yet relatively little is known about how IPs operate in practice, particularly how power dynamics influence platform processes.This paper focuses on a research-for-development project in the Ethiopian highlands which established three IPs for improved natural resource management.
En México y en el mundo, la incorporación de la comunidad científica (entre ellos los ecólogos) a la generación de conocimientos que coadyuven a solucionar los graves problemas ambientales, y avanzar hacia la sustentabilidad, requiere de una visión diferente en la investigación. Más aún, se requiere de herramientas novedosas para acoplar el trabajo de la comunidad científica con el resto de la sociedad.
Este artículo inicialmente aborda a la gestión del conocimiento como factor de desarrollo de una sociedad o de una región. Gestionar conocimiento implica generar condiciones para la creación e intercambio de conocimiento, para apoyar estos procesos es necesario articular sistemas organizativos que promuevan la activación de capitales intangibles y endógenos, como el conocimiento.
