Pełny tekst źródłaL'imprévisibilité des présentes précipitations saisonnières et des répercussions potentielles du changement climatique, ainsi que les besoins alimentaires grandissants d'une population croissante, mènent à une compétition plus acharnée entre les utilisateurs des ressources en eau, imposant ainsi d'importantes pressions sur la demande en eau à fins agricoles. Pour que l'agriculture irriguée au Canada puisse contribuer de façon significative à la résolution de présents et futures problèmes d'approvisionnement alimentaire mondial, des modes de gestion d'irrigation plus innovateurs et durables sont nécessaires. Dans ce contexte, un système d'aide à la décision assurant une plus grande efficacité d'allocation, d'application et d'optimisation des eaux d'irrigation fut conçue. Les études en serre établirent un régime d'irrigation approprié pour les poivrons et notèrent leurs réponses agronomiques et physiologiques à des stress hydriques lorsque cultivés sur un sol argileux ou un sable loameux. Quatre niveaux d'irrigation furent évalués, soit 120% (T120), 100% (T100), 80% (T80) ou 40% (T40) de l'évaporation bac (Ebac). Un réapprovisionnement à 120% Ebac entraîna un rendement et une efficacité d'utilisation de l'eau plus élevés sur le sable loameux que sur le sol argileux. L'indice de stress hydrique (ISH) de la culture soumise au taux de réapprovisionnement de 120% fut de 0.18 à 0.20 sur le sol argileux, et de 0.09 à 0.11 sur le sable loameux. Comme les résultats en serre furent obtenus sous des conditions hautement contrôlées, il fut nécessaire d'étendre la recherche à une culture en champ. Une étude fut entreprise sur un sol argileux pour déterminer quel seuil de pourcentage d'eau disponible dans le sol (85%, 75%, 50%, ou 25%) devrait entraîner une irrigation visant à prévenir un stress hydrique du plant de poivron et la perte de rendement qui en suivrait. Un étalon n'ayant reçu aucune irrigation fut également inclus. L'indice de stress hydrique (ISH) fut suivi et l'effet de teneurs élevés en CO2 sur la conductance stomatique et la quantité d'eau devant être appliqué furent également étudiés. Les trois teneurs en CO2 évalués furent celles de l'air ambiant présent (~400 ppm), et les teneurs prédites pour 2050 et 2100 (550 et 750 ppm, respectivement). Un rendement commercialisable optimal fut obtenu avec un seuil d'irrigation représentant à une carence de 50% en eau disponible du sol, ce qui correspond à un indice de stress hydrique de 0.3 à 0.4. Par rapport aux besoins en irrigation sous la présente teneur en CO2 de l'air ambiant, ces besoins diminuèrent de 6 à 42% sous une teneur en CO2 de 550 ppm, et de 28 à 58% sous une teneur en CO2 de 750 ppm. Un modèle intégré de demande en eau pour fins agricoles (MIDEFA) permettant l'estimation des besoins en eau d'irrigation (BEI) fut élaboré en utilisant l'interface graphique de Matlab. L'élaboration du modèle nécessita des données d'entrée de radiation solaire (Rs) de haute qualité. Laquelle de neuf méthodes permettant d'estimer Rs conviendrait le mieux fut évalué en utilisant des données parvenant de huit stations météorologiques canadiennes. Avec une erreur quadratique moyenne de 1 à 6%, la méthode Hargreaves et Samani (H-S) donna les meilleurs résultats. Les données tirées du MIDEFA furent comparées à celles tirées de simulations avec CROPWAT, et aux données provenant d'un compteur d'eau utilisée à fins d'irrigation. Les différences entre le BEI mesuré au champ et ceux calculés par MIDEFA et CROPWAT furent de 7 à 28% et 7 à 42%, respectivement. De futures BEI furent estimés en utilisant des données fournies par Agriculture et Agroalimentaire Canada (AAC), reflétant le changement de climat prévu pour 2040 et 2069. Selon cette analyse, le BEI pour les poivrons augmenterait de 19 à 27% dans l'avenir.Dans l'ensemble les constats de notre étude ont mené à une production de légumes plus durable à la fois en serre et au champ.

Pełny tekst źródłaA história do avanço da fronteira agrícola no Brasil tem sido intrinsecamente relacionada ao desmatamento. Embora perdas ambientais sejam, por vezes, inevitáveis no contexto de uma expansão agrícola, elas devem ser reduzidas sempre que possível. Tentando não seguir um padrão de desenvolvimento feito à custa de desmatamentos, e pensando numa forma mais sustentável de expansão da agricultura, nós avaliamos nesse estudo a possibilidade de expansão agrícola, para produção de alimentos e de biocombustíveis, sem o comprometimento do ecossistema natural existente no país. O Brasil tem um grande potencial agrícola atribuído à significativa quantidade de solos aptos para agricultura com clima e topografia favoráveis. Para abastecer o mercado agrícola nacional e assumir uma posição de liderança global na exportação de alimentos e biocombustíveis, ações devem ser tomadas pelo Brasil para o planejamento desse potencial de expansão. Esse planejamento seria um modelo alternativo para o avanço da fronteira agrícola, oposto aos padrões de avanço anteriores diretamente relacionados ao desmatamento. Uma forma de conseguir um padrão de desenvolvimento sustentável poderia ser pela identificação de terras agrícolas aptas à essa expansão sem estimular maiores perdas de florestas. As pastagens ocupam grandes áreas no Brasil e são consideradas recursos estratégicos para a eficácia dessa expansão, uma vez que representam áreas que já foram desmatadas e oferecem algum tipo de infraestrutura. Dado o atual potencial biofísico de produção, estima-se que as áreas de pastagem destinadas à pecuária bovina podem estar sendo subutilizadas. O objetivo desse trabalho é desenvolver um modelo de alocação espacial fundamentado numa análise de decisão multicritério e SIG com base na aptidão agrícola das terras, de forma a fornecer informações geoespaciais estratégicas aos tomadores de decisão sobre a localização das áreas potenciais para a expansão da cana-de-açúcar e soja no Brasil. A análise de decisão multicritério (MCDA) consiste na integração de dados edafoclimáticos, de infraestrutura e socioeconômicos para a identificação das áreas de pastagens aptas para a alocação dessas culturas. Para aumentar a confiabilidade do modelo, uma equipe de especialistas em cana-deaçúcar e soja foi selecionada para julgar a prioridade das variáveis no processo de análise. A combinação dos julgamentos fornece uma prioridade geral das variáveis, as quais alimentam o modelo. \"E se\" cenários foram também elaborados para mostrar como as mudanças nos pesos dos critérios modificariam a distribuição espacial das classes de aptidão com relação ao modelo principal. Os resultados são exibidos através de mapas que representam a distribuição das classes de aptidão agrícola para a alocação dos cultivos da cana-de-açúcar e soja. As pastagens tornam-se tanto mais adequadas para a alocação da cana ou soja de acordo com as mudanças na influência de cada critério no modelo. Os modelos projetados mostram resultados favoráveis que podem ajudar os tomadores de decisão com informações geoespaciais que identificam áreas prioritárias onde investimentos e esforços deveriam ser direcionados para estimular a expansão agrícola sustentável no Brasil.

Sin embargo, hay pocos estudios sobre los riesgos y beneficios tanto para el medio ambiente como para la salud humana, probablemente debido a la complejidad del problema y las altas expectativas de los participantes en la toma de decisiones. El objetivo de esta tesis fue desarrollar métodos para la gestión de lodos de depuradora en suelos agrícolas. Se desarrollaron, evaluaron e integraron modelos de transporte, exposición humana y riesgos para la salud. Así mismo, se construyeron modelos de decisión y se integraron en Sistemas de Información Geográfica (SIG) para indicar las mejores zonas agrícolas donde aplicar lodos de depuradora. El uso de estas herramientas proporciona decisiones más fiables con respecto a esta práctica.

Pełny tekst źródłaLa gestion des ressources naturelles s'est considérablement améliorée pendant la décennie passée. Malgré les avances dans la modélisation du destin des nutriants ou dans le domaine de modélisation des effets socio-économiques de différentes stratégies de gestion agricole, il nous manque toujours les outils d'intégrer les avances dans ces domaines. Afin de créer un outil d'integration de ces avances, cette recherche s'est concentrée sur le développement d'un système de soutien à la décision à objectifs multiples pour alléger la contamination de phosphore (P) à partir des champs agricoles et des petites lignes de partage. Le système inclut une interface de soutien à la décision permettant aux utilisateurs techniques et au grand public d'utiliser le MODSS. Le MODSS est composé des éléments suivants: plusieurs modèles de pollution diffuse, un système spécialisé pour analyser le produit de sortie d'un modèle de phosphore qualitatif, une routine de création de scénario, une routine pour estimer la réduction du phosphore en termes de pourcentage et de charge, une routine d'analyse avantages-coûts et une routine d'analyse d'échanges. Le développement du MODSS nécessitait la proposition d'un index du phosphore adapté au sud du Québec. Une nouvelle classe de risques a été introduite dans le paramètre de drainage souterrain: le drainage souterrain contrôlé. Cette classe de risques a été ajoutée, puisque des résultats de recherche extérieurs suggéraient que le drainage souterrain constitue une voie importante de perte du phosphore dans le sud du Québec. L'index modifié du phosphore a été couplé avec une routine d'examens préliminaires afin de raccourcir l'analyse. Le MODSS a été appliqué au bassin-versant de Castor au Québec, Canada. L'analyse a démontré les causes probables du mouvement de phosphore provenant des champs du bassin-versant de Castor : la distance par rapport au point d'origine, la connectivité$

The aim of this work is to present a proposal of integration between Precision Agriculture, DataWarehouse / OLAP and GIS. The integration should use extensible and open components, agricultural modeling for decision support, geographical data support, communication interface between components, extension of existing GIS and Data Warehouse solutions. As a result of the integration, an open and extensible architecture was defined, with a spatial agricultural data warehouse modeling. In this way the technologies and tools are open and allow the implementation and extension of its functionalities to adapt to the agricultural scenario of decision. In order to perform the integration, the data were obtained from a farm in the city of Piraí do Sul/PR, which uses proprietary software for data management. Data was exported to the SHAPEFILE format, and through the process performed by the ETL tool, was extracted, transformed and loaded into the analytical database. Also as a source of political boundaries data of rural regions of Brazil, data from the IBGE were used. The database was modeled and implemented by PostgreSQL DBMS with the extension PostiGIS to support spatial data. To provide the OLAP query service, was used the Geomondrian server. The application was extended from the Geonode project, where it was implemented Analytic functionalities, and the interface between the application and the OLAP was performed by the Mandoline API and the OLAP4J library. And finally the interface was implemented through javascript libraries for creating charts, tables and maps. As principal result, an architecture was obtained for Data Warehouse integration, OLAP operations, agricultural and spatial data, as well as ETL process definition and the user interface.
O objetivo desta dissertação é apresentar uma proposta de integração entre agricultura de precisão, Data Warehouse/OLAP e SIG. A integração deve utilizar componentes abertos e extensíveis, modelagem agrícola para suporte a decisão, suporte a dados geográficos, interface de comunicação entre os componentes e a extensão de soluções existentes de SIG e Data Warehouse. Como resultado da integração foi definido uma arquitetura aberta e extensível, integrada, com uma modelagem de Data Warehouse agrícola espacial, que permite o suporte a tomada de decisão para o planejamento e gestão do manejo das práticas da agricultura de precisão. Desta forma as tecnologias e ferramentas utilizadas são abertas e permitem a implementação e extensão de suas funcionalidades para adequar ao cenário agrícola de tomada de decisão. Para realizar a integração foi utilizado os dados oriundos de uma fazenda localizada em Piraí do Sul/PR, a qual utiliza um software proprietário para o gerenciamento de dados. Os dados foram exportados para o formato SHAPEFILE, e através do processo realizado pela ferramenta de ETL, foram extraídos, transformados e carregados para a base de dados analítica. Também como fonte de dados sobre as fronteiras políticas das regiões rurais do Brasil, foi utilizado dados do IBGE. A base de dados analítica foi modelada e implementada em um SGBD PostgreSQL com a extensão PostiGIS para suportar os dados geográficos. Para prover o serviço de consultas OLAP, foi utilizado o servidor Geomondrian. A aplicação foi estendida do projeto Geonode, onde foi implementado as funcionalidades analíticas, e a interface entre a aplicação e o servidor OLAP, foi realizada pela API Mandoline e a biblioteca OLAP4J. E por fim a interface foi implementada por meio de bibliotecas javascript para a criação de gráficos, tabelas e mapas. Como principal resultado, obteve-se uma arquitetura para integração de datawarehouse, operações OLAP, dados espaciais e agricultura, bem como definição do processo de ETL e a interface com o usuário.

Resumo: Este trabalho teve como objetivo o desenvolvimento de um sistema de apoio à decisão para a gestão da terra, integrando um Sistema Especialista para determinar a capacidade de uso da terra e outro para recomendar usos adequados e as práticas de conservação e manejo do solo, um Sistema de Informações Geográficas (SIG), uma base de dados e uma interface para interpretar a entrada de dados do usuário e as mensagens passadas entre os sub-sistemas. Todos os diálogos entre o usuário e o sistema são realizados pela da interface, assim como a comunicação entre os componentes do sistema desenvolvido. Os sistemas especialistas foram desenvolvidos utilizando o ¿shell¿ conhecido como CLIPS (C Language Integrated Production System) que provê um ambiente para a construção de sistemas especialistas. O SIG utilizado foi o IDRISI, versão 32, que possui o módulo Applications Programming Interface - API (Interface de Programação de Aplicativos) com um OLE Automation Server, possibilitando o uso de linguagens de alto nível, tais como Visual Basic, para controlar as operações do Idrisi32. A base de dados foi desenvolvida com a utilização do Microsoft Access®, além disso, é de fácil acesso, pois a maioria dos usuários tem esse aplicativo instalado em seus computadores. O sistema desenvolvido determina a capacidade de uso da terra; recomenda usos adequados para cada classe de capacidade de uso; recomenda práticas de conservação e manejo do solo; e identifica áreas de conflito comparando os mapas de uso da terra da região em estudo com o mapa de capacidade de uso. Todos os resultados podem ser visualizados em janelas do programa, gravados ou impressos em formas de relatórios. A validação do sistema foi feita comparando as saídas do sistema com os resultados obtidos de quatro especialistas. As divergências encontradas mostraram que o sistema desenvolvido foi mais rigoroso, principalmente no que diz respeito ao risco de erosão, determinando classes de capacidade de uso diferentes das determinadas por alguns especialistas. Quanto ao tipo de uso e às práticas de conservação e manejo do solo, foram poucas as divergências encontradas. A área utilizada para testar o sistema é o Município de Santo Antônio do Jardim - SP. O sistema classificou 36,95% das terras do município como adequadas para a utilização com cultura anual ou perene; 42,69% são adequadas para pastagem e reflorestamento e 19,51% devem ser utilizadas para preservação ambiental. Outro resultado apresentado é o mapa de intensidade de uso, no qual pôde se observar que 48,50% do município está sendo utilizada de forma adequada; 31,82% com uso inadequado e, 14,06% apresenta subutilização. O sistema mostrou ser uma ferramenta poderosa e eficaz, permitindo avaliar uma região, dando suporte para uma tomada de decisão mais fundamentada
Abstract: The objective of this work was to develop a decision support system for agricultural land environmental planing, which integrates an Expert System to determine the land capability and other to recommend adequate uses and practices for soil conservation and management, Geographic Information System (GIS), a database and an interface to monitor input and output data and the messages passed between the subsystems. The management of all the system is made by an interface developed in Visual Basic, version 5.0. All the dialogues between the user and the system as well as the communication with the components of the system are made through the interface that shows windows, menus, dialog boxes, maps and reports in the screen. It saves the results in files and prints them. The expert systems were developed with a shell known as CLIPS (C Language Integrated Production System), that provides an environment for building expert systems. The GIS was IDRISI, version 32, that has Applications Programming Interface ¿ API with an OLE Automation Server, and makes possible to use high-level languages, such as Visual Basic for controlling the operation of Idrisi32. The database was developed with the Microsoft Access®, because of the majority of the users have this software installed in its computers. The developed system determines land capability from information stored in the database and, also supplied for the SIG, through the soil and slope maps; it recommends adequate uses for land capability class; it recommends practices for soil conservation and management and identifies conflict areas comparing the maps of land use with the land capability. All the results can be visualized by the user through windows of the program, recorded or printed in forms of reports. The validation of the system was done comparing the system outputs with the results obtained of four experts. The divergences have shown that the system was more rigorous than the experts, specially concerning the erosion risk, leading to different land capability classes from those determined for some experts, in some cases. Concerning to the type of practices for soil conservation and management, the divergences have been few. In order to test the system, the county of Santo Antônio do Jardim ¿ SP was selected. The system classified 36.95% of lands as adequate for the use with annual or perennial cultures; 42.69% are adequate for pastures and reforestation and 19.51% must be used for environmental preservation. Another presented result is the map of intensity use, through which could be observed that 48.50% of the lands are being used of adequate form; 31.82% of the lands presents inadequate use and, 14.06% presents under utilization. The system is a powerful and efficient tool, what makes it possible to evaluate a region and give support to a more adequate decision making

Pełny tekst źródłaThe next evolution of agriculture is Agriculture 4.0. Agriculture 4.0 is about using technologies ofthe Internet of Things (IoT) and Context-Aware Systems (CASs) to increase the performance offarming activities. A CAS can react automatically and adequately to the environment based onits context. Applying CASs in agriculture can reduce farm labor and increase the precision offarming activities. However, it encounters two challenges specific to agriculture. The firstchallenge relies on the need to upgrade a CAS regularly with new computing devices orsoftware programs without changing its functionality. Indeed, natural factors, such as violentweather and wild animals, can damage the computing devices located on farmland. Moreover,after each farming season, farmers may need to upgrade their system with new computingdevices and software programs. The second challenge is the data heterogeneity generated froma CAS. In agriculture, various phenomena involve the need to have different sensor devices thatmake numerous types of measurements and produce heterogeneous data. Representing all ofthese heterogeneous data is necessary for the interoperability of different computing devices ina CAS or the interoperability between different CASs in the IoT ecosystem. This thesis proposesthree contributions. The first contribution addresses the first challenge. It is a new architecturebased on the microservice mindset that allows system developers to focus on the services’goals rather than the computing devices and software programs of a CAS. This newarchitecture is called the stack of services for CASs. The second contribution addresses thesecond challenge. It is a new ontology for CASs named CASO. The ontology provides avocabulary to model heterogeneous data generated from CASs and embodies a mechanism tomake rules for reasoning. The third contribution is to build a decision support system (DSS) forthe irrigation CAS in the research unit TSCF, INRAE. The design of the DSS relies on the stackof services for CASs. Moreover, the DSS uses a new ontology called IRRIG, a specialization ofCASO for irrigation. The DSS is an automation version of the manual irrigation methodIRRINOV®. All the guidelines for farmers in IRRINOV® are transformed into rules for reasoning.The contributions of this thesis are going to be applied to build a smart irrigation CAS deployedin AgroTechnoPôle, located in Montoldre, France

The opportunity exists for the DoD's private aircraft operation, the Joint Operational Support Airlift Center (JOSAC), to utilize some of the same system features used in commercial operations such as NetJets to improve operations. This thesis will analyze the use of commercial air operator strategies and DSS's to be used in JOSAC to improve operational effectiveness. It will look to add new capabilities and processes used in commercial DSS's along with the implementation of the disruptive technology, microjets. Some of the potential benefits include improved operational performance, solutions to scheduling inefficiencies and improved mission readiness. With these improvements the potential for a military microjet operation in the future is a real possibility.

Resumo: A ferrugem asiática, causada pelo fungo Phakopsora pachyrhizi, atualmente é considerada uma das doenças mais importantes e agressivas da soja. A principal forma de controle é a aplicação calendarizada de fungicidas a qual desconsidera o risco de ocorrência da doença. Estudos epidemiológicos buscam compreender os fatores que influenciam na ocorrência e desenvolvimento das epidemias, especialmente aqueles relacionados ao ambiente tais como condições meteorológicas. Com o avanço da tecnologia da informação e do armazenamento de dados, técnicas de mineração de dados (data mining) apresentam-se promissoras para a descoberta de conhecimento em bases de dados epidemiológicos. Este trabalho tem como objetivo avaliar a influência da chuva e da temperatura na ocorrência da ferrugem asiática da soja utilizando árvores de decisão. Para tal, foram obtidos dados de ocorrências da doença em quatro safras, de 2007/2008 a 2010/2011, oriundos do banco de dados do Consórcio Antiferrugem, e dados meteorológicos, provenientes do sistema Agritempo. A análise exploratória dos dados permitiu obter subsídios para compor o conjunto de dados final e definir o escopo deste trabalho, buscando-se características intrínsecas à doença e sua interação com o ambiente, utilizando apenas variáveis de base meteorológica. As variáveis utilizadas foram relacionadas à precipitação e à temperatura, que deram origem a nove atributos avaliados para cada período temporal...Observação: O resumo, na íntegra, poderá ser visualizado no texto completo da tese digital
Abstract: The Asian soybean rust, caused by Phakopsora pachyrhizi, is now considered one of the most important and aggressive diseases of soybean. The main form of control is the scheduled application of fungicides which disregards the the risk of disease occurrence. Epidemiological studies seek to understand the factors that influence the occurrence and development of epidemics, especially those related to the environment such as weather conditions. With the development of information technology and data warehousing, data mining techniques appear to be promising for knowledge discovery in epidemiological databases. This study aims to evaluate the influence of rainfall and temperature on the occurrence of soybean rust by using decision trees models. To accomplish that, data of the occurence of the disease were collected from four seasons, 2007/2008 to 2010/2011, from the Consórcio Antiferrugem and weather data from the Agritempo system. Exploratory data analysis allowed for obtaining subsidies to generate the final data set and define the scope of this work, seeking intrinsic characteristics of the disease and its interaction with the environment, using only meteorological variables. The variables used were related to precipitation and temperature, resulting into nine attributes evaluated in different periods. Such attributes were related to the event of occurrence (Oc) and non occurrence (NaoOc) of the disease (assumed as the thirtieth day prior to the event of occurrence). The results include a predictive model and an interpretive model for classifying events of occurrences and non occurrences of the disease...Note: The complete abstract is available with the full electronic document

Pełny tekst źródłaThe aim of this study was the design and implementation of an interactive decision support system, assisting a single decision maker in reaching a satisfactory decision when faced by a multicriteria decision making problem. There are clearly two components involved in designing such a system, namely the concept of decision support systems (DSS) and the area of multicriteria decision making (MCDM). The multicriteria decision making environment as well as the definitions of the multicriteria decision making concepts used, are discussed in chapter 1. Chapter 2 gives a brief historical review on MCDM, highlighting the origins of some of the more well-known methods for solving MCDM problems. A detailed discussion of interactive decision making is also given. Chapter 3 is concerned with the DSS concept, including a historical review thereof, a framework for the design of a DSS, various development approaches as well as the components constituting a decision support system. In chapter 4, the possibility of integrating the two concepts, MCDM and DSS, are discussed. A detailed discussion of various methodologies for solving MCDM problems is given in chapter 5. Specific attention is given to identifying the methodologies to be implemented in the DSS. Chapter 6 can be seen as a theoretical description of the system developed, while Chapter 7 is concerned with the evaluation procedures used for testing the system. A final summary and concluding remarks are given in Chapter 8.
