Texto completoThe sustainability of irrigated agriculture is threatened by growing pressure on water resources, whose over-exploitation is leading to the degradation of ecosystems, especially in the Mediterranean basin. Despite investment in costly modern equipment, the performance of irrigation systems remains below expectations, notably due to induced effects on a wider scale. Digital information technologies offer new opportunities for better understanding and management of water resources, but they remain relatively inaccessible and poorly adapted to agrarian contexts, particularly for surface irrigation systems and in the global South. Therefore, to what extent can the participatory design of digital information technologies result in new tools that are useful and accessible to improve the performance of irrigation systems and contribute to greater territorial sustainability? The results of our PhD thesis show that digital innovation for irrigation management does not necessarily have to be complex, expensive and energy-intensive. We developed new simple, open source, do-it-yourself and low-cost measurement and automation systems to support real-time water management with farmers practising surface irrigation in France and drip irrigation in Tunisia. We proposed a multi-criteria and multi-scale modeling method to simulate the effects of the adoption of such new tools on the performance of irrigation systems. Our results put into perspective the benefits of changes in practices resulting from the adoption of innovations, and illustrate the trade-offs emerging on a larger scale. We believe that this work will contribute to the democratisation of digital low-tech for more autonomous, energy and water-saving irrigation systems. The designed tools and methods are highly reproducible and open the way to future research on the understanding and management of water flows in various agro-hydrological contexts

Texto completoAgriculture 4.0, also known under several aliases such as ‘digital agriculture', ‘smart farming', and ‘e-farming' is currently developing rapidly in terms of research, development, and commercial applications. As with Agriculture 1.0, 2.0, and 3.0, the objective of Agriculture 4.0 is the use of technology to improve all areas of agriculture. In Agriculture 4.0 it is the application of microelectronics and microtechnologies. Unlike before, these technologies bring things such as the internet-of-things, big data, telecommunications, novel sensing, rapid feedback, data analysis, connectivity, artificial intelligence etc. In principle, all these areas should result in a massive modernization of farming in terms of organisation, yield, efficiency, and quality of produce. However, Agriculture 4.0 is so vast that if one is to contribute to it, even in a minor way, one has to choose a specific area to contribute. The area chosen for the study in this PhD was flax fibre production. Flax fibres are naturally strong fibres which can be extracted from flax stems. The flax stems have evolved to have robust micrometre-diameter fibres running the length of the outside of the stem, and held in place in the external tissue of the stem. Once extracted and isolated, flax fibres have numerous applications ranging from textiles to composite materials. In order to facilitate the mechanical extraction of flax fibres from their parent stems, the stems undergo a process known as ‘retting'. Retting leads to the breakdown of the external tissue between the fibres. A common form of retting is known as ‘dew retting'. In dew retting, natural processes such as bacteria and fungi result in enzymes which break down the middle lamella and gradually separate fibre bunches and fibres from bunches. The length of dew retting depends heavily on the weather. Too little retting results in difficult fibre extraction in the factory, too much retting can result in a compromise in fibre quality. It has long been known that there is an optimum retting point-even the ancients knew this. Certain skilled artisan farmers are able to judge this point via a combination of manual manipulation of the stems, observation of damage caused to the external tissue via this manoeuvre, and also observing the colour and the smell of the stems during this very skilled, but artisanal, testing. It is clear that the artisan is performing rudimentary laboratory tests quite literally ‘in-the-field'. It would seem logical therefore to try to quantify such tests and see if a reliable tool can be made to help the artisan. And indeed, this is exactly what others have attempted. The introduction of the PhD gives examples of attempts to make optimal-retting tools in the 1980s and after. Inspired by this early work, the work of this PhD attempts a full multiscale mechanical characterization of flax stems and fibres during a retting cycle (summer 2022) and, somewhat ambitiously, performed in real time-to our knowledge for the first time. The mechanical characterization involved macroscopic mechanical tests (bending, crushing, and twisting), as well as novel microscopic mechanical testing of single flax fibres using novel methods inspired by MEMS. In addition, the nanoscopic mechanical properties of the primary cell wall of retting flax fibres was characterised using nanoindentation AFM. As the experimental work, analysis via analytical modelling, and interpretation descends in scale from macro, through micro, to nano, we learn a little more of how the retting affects the stems, their properties, and their fibres. In addition to simply learning, a very positive outcome of the PhD is that one is able to suggest a mechanically-induced damage mechanism in stems which could be the basis for a tool. One can note however, that the uncontrollable multiparameter nature of the subject, e.g. the weather, means that several studies would be needed to confirm beyond doubt observations from a single retting cycle

Texto completoLes principales difficultés pour extraire des images l'information utile ont été rencontrées au niveau de la segmentation des images, ce qui explique que les principaux apports méthodologiques de ce travail se situent au niveau des premiers traitements réalisés sur l'image. Nous proposons une technique de transformation non linéaire de l'histogramme des niveaux de gris qui permet d'optimiser la recherche automatique d'un seuil et ainsi fiabiliser les procédures classiques de segmentation par seuillage d'histogramme. D'autre part, les propriétés de luminance des points ne permettant pas toujours, à elles seules, de trouver un seuil approprié, nous proposons une nouvelle approche de la segmentation pour laquelle les propriétés de connexité et de luminance des points sont prises en compte conjointement pour segmenter de manière automatique l'image en autant de régions que nécessaire. Ce travail de recherche a finalement abouti par la réalisation d'une machine prototype qui intègre un système de vision artificielle pour l'examen du degré de croissance et de conformité des produits avant leur expédition chez les clients

The case of knowledge-based platforms for farmers in Kenya". Thesis, Université Paris-Saclay (ComUE), 2018. http://www.theses.fr/2018SACLA018/document.
Texto completoLow-income sub-Saharan African countries are confronted with demographic explosion since the last 60 years. Consequently, agriculture plays a key role in ensuring food security. The agricultural sector is also the main source of employment in this region. Women are the major contributing labour force in agriculture in these sub-Saharan African countries. Connected to their key role in the agricultural sector, women farmers are prioritised in policy intervention. Moreover, agricultural extension services are necessary to adapt to different constraints in these countries. Transfer of knowledge is also required to guarantee farm yields and consequently improve small-scale farmers’ livelihoods. Lately, information and communication technologies (ICTs) have enabled the development of new tools, aimed at improving the scope and the effectiveness of advisory services. Policy makers in sub-Saharan African countries are nonetheless confronted with critical questions regarding the impact of these tools, which can also contribute to a ‘digital gender gap’. These issues particularly concern women farmers.This PhD research analyses how ICT tools take into account gender relations, and the situation of women farmers. The thesis is based on the case of Kenya. The dissertation particularly focuses on the development of knowledge-based platforms in agriculture, an ICT policy instrument used by the Kenyan Government to achieve public policy objectives. This country is emblematic because it believes in the assumption that platforms can be inclusive of women farmers’. To answer to this research question, the work is based on three different institutional economic research approaches: feminist economics, the French regulation theory, and economics of services. A conceptual and methodological framework is presented to analyse the inclusion of gender equality in knowledge-based platforms at macro-, meso-, and micro- level.The results provide evidence that gender equality objectives is a fundamental guiding principle to the Government of Kenya. The analysis show that platforms are considered as new tools of inclusiveness in farm advisory services innovation. Observations from a developed platform typology framework show however that platforms can be source of gender inequality. It especially concerns women farmers unequal access to these instruments and the standardised services that they offer. This is essentially related to the institutional nature of the platform. Indeed, as it turns out, a high number of these instruments are based upon complex partnerships, and financed by multi-national corporations and/or foundations from the agrifood industry based in the Northern hemisphere. Combining institutional economic approaches allowed to bring out critical points of inclusion to be considered by policy makers and platform developers. Disregarding these specificities may make these platforms into new vectors of exclusion. Recognising and taking into account the conditions for inclusion can bring to light powerful levers for improving the efficiency of platforms

Texto completoWeed detection is one of the most important issues for a non-polluting and productive agriculture. In this PhD we present a new method based on aerial images acquired with a remote controlled aircraft. We use a multispectral image sensor based on a CCD camera and a wheel of filters. This sensor is compact enough to be shipped in a remote controlled aircraft. An image mosaicing is done in order to be able to use spectrometric information. Later, spectral information is used to establish three classes : soil, crops and weeds. Classification is split in two steps. First, a non-supervised algorithm allows the separation between soil and plants. Second, supervised methods are used to distinguish crops and weeds. These various algorithms are compared to each other. A crop row detection method based on Gabor filter is developed. This information allows weeds/crop separation regardless of their spectral characteristics. An original method for computing time acceleration based on wavelet packets is detailed. These two methods having different error sources, we suggest to merge them using a Bayesian approach. Finally, a region growing algorithm achieves the classification. Experimental results obtained in test fields are provided to assess the quality of the classification

Texto completoPlant (crop and weed) identification is a very active field of research in agriculture since the reinforcement of European laws about pesticide applications for a site-specific management of spraying practices. A new crop/weed simulation model was developed to allow the evaluation of crop/weed spatial identification methods from imaging. Considering multiples agronomic parameters – crop location, weed infestation rate, weed spatial distribution – the first step of this model allows the simulation of an infested crop field. Then, in a second step, a world to camera transformation is applied to allow every kind of picture (with or without perspective effect). The validation of this model was performed using statistical tests comparing a real image to its homologous virtual one. New crop/weed discrimination algorithms based on the Hough Transform to detect crop rows were also developed. Three methods, using the crop row information and based on a blob-coloring, an edge estimation or a probabilistic classification were exhaustively tested using this model. Results show very good performance of these methods with correct average classification rate of 90% and up to 98% under special conditions. A spectral approach was also explored for the model in order to overcome the limitations imposed by spatial algorithms. Crop and weed plant patterns are now in 3D to allow the calculation of the bidirectional reflectance (BRDF) of plants and soil based on PROSPECT and SOILSPECT models. We also discussed the transformation of a reflectance spectrum into a RGB color, the simulation of optical filter effects and the creation of multispectral images
