Dealing with Uncertainties in IT Solutions for Agriculture

Technology is essential for the improvement and efficiency of activities in the agricultural environment. Nevertheless, farmers and IT’s worlds are distant. Usually, IT services fail to provide the correct solution and farmers are reluctant to incorporate new IT advances. IT teams need to acquire agricultural knowledge and language in order to communicate, to reduce the distance, and cooperate. Nevertheless, during this process and particularly, in agriculture, there are many uncertainties. If they are not clearified, it will not be possible to provide the right IT solution. These un-certainties are translated as a lack of precision in the requirements specifica-tions. Sometimes, it is as easy as elicit more information from the stake-holders to improve the specification. In some other situations, the stakeholders have different points of view and they need to reach a concen-sus. These uncertainties are hard to identify. IT teams and farmers must speak the same technical and specific language and the IT team needs a complete and exhaustive specification about how software applications must react. Agriculture is a biological environment with many rules and de-cisions that are not easy to make explicit. Therefore, it is important to in-volve a group of farmers as with complementary and different point of view. Thus, this article proposes an approach to deal with uncertainties in order to provide the unambiguous and complete specification. The approach relies on capturing knowledge through scenarios. It consists of three main steps to obtain the scenarios: (i) a collaborative knowledge acquisition, (ii) scenarios description and analysis, and (iii) group decision support

GAP-a-Farm: A tool to support GAP compliance and information based decision making in horticulture

Adoption of information technology in horticulture is low, especially in developing countries. Governments across the world issue new regulation to govern the application of good agricultural practices affecting production, storage and selling activities, while certification program require that farmers keep detailed records of farm events, for auditing purposes. These changes in the context of horticultural practices, represent an opportunity to test whether a compliance and decision support systems can shift farmers processes to utilize technology incorporating data and expert advice. GAP-a-Farm is a tool to ease record keeping, and to turn recorded data into alerts and advice. This chapter documents the key aspects of the system’s design, and reports on preliminary discussions with end-users that take part in a pilot study in Argentina

Agroknowledge: co-creation of a repository of agricultural best practices, to improve knowledge disemination and interoperability

Good Agricultural Practices (GAP), as defined by FAO, are a "collection of principles for on-farm production and post-production processes, resulting in safe and healthy food and non-food agriculture products, while considering economic, social and environmental sustainability." GAP are about understanding, planning and measurement, record, and management to achieve specific social, environmental, and productive objectives. GAPs goals are: to ensure food safety, to produce in a way that protects the environment and avoids its degradation, to ensure job well-being, and to obtain quality products according to consumer demand. For example, FAO enumerates general categories such as GAP for food safety, to improve market access or ensure water quality. GAP can be achieved by different actions depending on the crop, geography, available tools, and a diversity of variables. A federated catalog of GAPs that could be accessed by different stakeholders using different aspects is desirable. Also, as there are a diversity of GAPs experiences in the world, a catalog about those experiences is a helpful tool to help farmers exchange and adoption of knowledge. This chapter presents a semantic wiki repository that focuses on GAPs related to intensive horticultural activity in aspects that may be subject to improvement. The repository is framed in what is currently considered a collaborative repository. The wiki includes a description, goals, and methodologies of each good practice defined in GAP. Also, the wiki contains links to tutorials, external sites about the agricultural field, and legal documentation

Adopting and Adapting Design Thinking's Strategies in Distributed Research and Innovation Projects: A Case Study

Innovation is risky and challenging by definition. Only a small fraction of all innovation initiatives result in a successful new material, process or product. Networked research projects, as those conducted by a distributed consortium in-volving multiple domains and with global coverage, constitute an opportunity for innovation. However, the distributed nature of these projects introduces additional challenges, not present otherwise. The RUC-APS project is a European funded project whose goal is to enhance and implement knowledge based ICT solutions within high risk and uncertain conditions for agriculture pro-duction systems. Partners in the RUC-APS consortium are located in France, Italy, Poland, Spain, the United Kingdom, Argentina and Chile. Some of these partners are academic institutions, and some are companies, farms, or government dependent organizations. Partners have expertise in different domains such as computers sci-ence, business management, and agriculture. Interaction among partners —two or three partners at a time— takes place regularly throughout the year, in periods of one or two months of duration. This paper reports on a case study in which strategies of Design Thinking —which heavily depends on co-located, face to face interac-tion— were adapted to the distributed nature of the project. A proposal of how to adopt and adapt DT in distributed research and innovation projects is presented. In addition, a discussion is presented in relation to this kind of approach

Atmospheric microplastic accumulation in Ramalina celastri (Sprengel) Krog & Swinscow Thalli: a transplant study across different levels of urbanization

Lichens are widely recognized as bioindicators of atmospheric pollution, but studies on their role in monitoring microplastic (MP) deposition remain scarce. This study investigates MP accumulation in natural populations of Ramalina celastri across an urbanization gradient in Luján, Argentina, marking the first report for this species. MP concentrations ranged from 16.54 ± 3.59 MPs g–1 in baseline sites to significantly higher levels in urban zones. Fragments showed a stronger association with urbanised areas compared with fibres. Unlike larger urban centers, no significant trend was observed in MP size with urbanization, likely due to Lujan’s small size, facilitating unrestricted MP movement. Comparisons with global studies revealed consistent patterns of increased MP accumulation near anthropogenic sources, while unique findings highlight the potential of R. celastri as a bioindicator in diverse environments. These results emphasize the influence of urbanization on MP deposition and suggest localized sources as key contributors to fragments, advancing our understanding of MP dynamics. This work underscores the need for standardized methodologies to enhance comparability in future research on terrestrial MP pollution

Efecto de los parámetros de soldadura sobre la microestructura y la resistencia al desgaste de depósitos de soldadura base hierro nanoestructurados

El objetivo de la tesis fue el estudio en forma sistematizada de cupones soldados para recargues de aleaciones base Fe nanoestructuradas por medio de soldadura semiautomática con y sin protección gaseosa (FCAW y FCAW-S). Para ello se soldaron 4 cupones de 1 y 2 capas, con una aleación base Fe-(Cr,Nb)-(B,C) y 4 cupones con una aleación base Fe(Cr, Nb, W,Mo) –(B,C). En ambas probetas se soldó con alto y bajo aporte térmico. Para poder definir los parámetros óptimos para la implementación de los recargue mencionados anteriormente, se evaluaron 8 cupones soldados tipo “bead on plate” variando el aporte térmico en un rango de 0,5 a 3,5 kJ/mm por medio de la variación de la velocidad de soldadura. Para realizar el efecto de revenido entre pasadas y el comportamiento de las fases a altas temperaturas se realizaron tratamientos térmicos post-soldadura. La metodológica implementada consistió en preparar y soldar las aleaciones, realizar análisis de composición química, caracterización microestructural por difracción de rayos X microscopia óptica y electrónica de barrido (SEM), medición de micro dureza Vickers y determinación de propiedades tribológica de los depósitos. Por otro lado, se realizaron estudios adicionales para ahondar con mayor profundidad la problemática en estudio: -Estudio de dilución - Determinación de composición química local - Microscopia de barrido utilizando electrones secundarios y electrodifundidos -Cuantificación de fases y carburos. -Microscopia de transmisión (TEM). -Ensayos de desgaste abrasivo de tres cuerpos ASTM de G-65. -Ensayos de desgate de alta presión de dos cuerpos ASTM G-132. - Análisis SEM de superficie desgastadas. - Microscopia Confocal.Doctor en ingenierí

Estudio comparativo sobre la aplicación de librerías PNL para reconocimiento de entidades en la validación de requerimientos

Una tarea fundamental en el desarrollo de software es la validación de requerimientos, esto implica verificar que el producto desarrollado sea correcto y los requerimientos precisos, coherentes, completos y alcanzables. Hoy en día, los requerimientos se detallan en su mayoría en lenguaje natural sin restricciones para que cada parte interesada los entienda. Por lo tanto, la validación de los requerimientos y la transición al diseño basado en modelos, requieren mucho tiempo, son propensas a errores y, a menudo, son repetitivas debido a que se deben verificar muchos requerimientos. El procesamiento del lenguaje natural (PNL) incluye diferentes técnicas para interpretar el lenguaje humano, que van desde los métodos estadísticos y del aprendizaje basado en máquina hasta los enfoques basados en reglas y algorítmicos. Una de las técnicas derivadas del PNL es el Reconocimiento de Entidades Nombradas (por sus siglas en inglés, NER) que consiste en identificar y clasificar entidades de texto mediante el uso de librerías que combinado con la validación de requerimientos permite certificar que los requerimientos sean correctos y disminuye las posibilidades de encontrar errores. En este contexto las técnicas de procesamiento de lenguaje natural y la validación de requerimientos cobran importancia. Este artículo discute los aspectos más importantes de una línea de investigación iniciada en la Universidad Nacional de Entre Ríos (UNER) que tiene como objetivo desarrollar un proceso de validación de requerimientos utilizando, entre otras técnicas, procesamiento de lenguaje natural y entornos colaborativos

Subsurface Potential for CO2 Injection in Buenos Aires Province, Argentina: A Preliminary Study in the Claromecó Basin

In recent years, carbon capture and storage (CCS) has emerged as an essential alternative for transitioning towards an environmentally sustainable future. Reducing anthropogenic CO2 emissions constitutes a new paradigm driving the frontier of knowledge. In Argentina, the assessment of CO2 storage potential is in its early stages. The Claromecó basin is a Carboniferous-Permian foreland basin located in the center-east of Buenos Aires province, bounded by the Sierras Australes to the southwest and Tandilia System to the east-northeast. It has a total area of 65.000 km2, encompassing 40.000 km2 in the continental sector whose sedimentary infill correlates with the outcropping sequence in the Sierras Australes. The interest of this contribution lies on the presence of coal beds in the subsurface, interesting lithology for CO2 capture due to its high capacity of storage by adsorption. This study aims to further advance knowledge of CO2 storage potential linked to the stratigraphic record of the Claromecó basin, focusing on the regional presence of reservoir and seal rocks based on direct (core and microscope description) and indirect (geophysical) data of well drilling. Advances in-depth knowledge of potential CO2 storage reservoirs are of vital importance to improve understanding of the Buenos Aires province subsurface as potential site for carbon capture and storage (CCS)
