Abstract:

In recent times there is an increasing interest in the quantification of the variation in soil organic carbon (SOC) in space and time. Quantification of this variation is important since SOC is important for many soil physical, chemical and biological properties and soil processes which lead to sustainable crop production in agricultural soil. In addition, SOC also helps to reduce the impacts of climatic change if it can be stored in soil for the long term in what is called “soil carbon sequestration”. The focus of the work included in this thesis is to model the space and time variation using both statistical as well as process/mechanistic models of SOC. In process modelling of SOC, the Rothamsted carbon model (RothC model) was used to assess the spatial and temporal changes in SOC. The RothC model can be used to simulate the variation of SOC over the time using readily available spatial data. Therefore, this research has (a) tested the application of mid infra red / partial least-square regression models (MIR/PLSR models) in predicting SOC in archived soil data in combination with newly collected SOC data; (b) assessed changes in SOC using legacy soil data as the baseline survey; (c) mapped the measurable SOC fractions related to RothC model at the catchment scale; (d) simulated SOC across a catchment with the RothC model using readily available spatial data; (e) calibrated the rate constants of the RothC model at the catchment scale using Bayesian inverse modelling. The first research chapter (chapter 3) concentrates on the development of MIR/PLSR models to predict total SOC in archived soil datasets in relation to legacy soil datasets. The legacy soil information can be used to assess the temporal changes of SOC if they are considered to be the baseline survey. However, the use of legacy soil data directly for comparison will not be possible due to differences in the laboratory method used to measure SOC (analytical) and in the sampling support (see chapter 4 for more details). Therefore, an attempt was made to predict total SOC for archived soil data which corresponds to a legacy soil dataset collected in year 2000 in combination with newly collected data in year 2010. A total of eight (8) different MIR/PLSR calibration models were developed to predict SOC in archived soils. In development of these models an attempt was made to select samples (n = 24) from archived soil data using different sampling strategies which were used in combination (spiking) with the newly collected dataset for year 2010. It was found that all developed calibration models performed well based on internal cross validation. However, the independent validation results revealed sample selection through the Kernnard Stone algorithm performed best compared to other approaches, e.g. conditional latin hypercube sampling. In practical terms, it is not possible to analyse a large number of soil samples in archives with traditional lab based methods. Therefore, development of effective and practical oriented MIR/PLSR models will be cost effective and save laboratory processing time in relation to the determination of total SOC in archived soil properties. Chapter 4 is focused on the assessment of the change in SOC at the catchment scale using legacy soil data as the baseline survey. In this chapter two main approaches were used to assess the change in SOC namely; design-based inference methods and model-based inference methods. It also demonstrated “how to get design-based estimates when the sampling design is non-probabilistic” which is common for most legacy datasets. Design-based inference was carried out to see the change in SOC after calculating the 95 % confidence interval around the mean for the considered soil-land use complexes (SLU). If the 95 % confidence intervals for a considered SLU complex overlap each other, then it was concluded that the change is statistically not significant at the 0.05 probability level. In the model-based approach digital soil mapping (DSM) techniques were utilized where linear mixed models (LMM) were used to map the changes in SOC across the catchment. This chapter also reported issues with legacy soil data when they are used as the baseline survey and some of the ways to overcome those issues. Both statistical inference methods revealed that there is a drop in SOC between the two surveys (year 2000 and year 2010). However, that drop was not reported as statistically significant at the 0.05 probability level for both inference methods. Chapter 5 is focused on mapping measurable fractions of the RothC model at the catchment scale. The measurable fractions of the RothC model were predicted based on MIR spectra acquired for the 2010 dataset using newly developed MIR/PLSR models from the Australian carbon research programme (SCaRP) lead by CSIRO (2009 – 2012). Even though there are many papers related to mapping SOC there are only very few papers that are available related to mapping of SOC fractions. According to the reviewed literature this is the first time that measurable fractions of SOC related to the RothC model have been mapped. For the mapping purposes three separate LMMs were used and developed models were validated with leave-one-out-cross validation. In addition, conditional sequential Gaussian simulations were carried out to assess the uncertainties related to predicted maps. Throughout this chapter it is discussed how these DSM outputs can be used as inputs to the RothC model in order to run it spatially. Finally chapter 6 and 7 are focused on process modelling of SOC with RothC model. Chapter 6 highlights different ways of running RothC model spatially across a catchment. As the first step, the RothC model was initialized across the landscape using different initialization methods. A novel approach was tested where temporal C inputs were predicted from MODIS derived NPP data. Once data is prepared simulations across landscapes were carried out with 50 model combinations. These different model combinations consisting of different rate constants (2 levels), methods of initialization (5 levels) and sources of C inputs (5 levels) were compared (2 × 5 × 5 = 50 model combinations). It was found that different methods of initialization resulted in statistically significant initial SOC pools that are used as part of the RothC model. Further, it revealed that at the end of the simulations, (after 10 years) total SOC was statistically different at the 0.05 probability level based on different combinations. Results highlighted that there is great potential to use satellite derived products as drivers for future modelling of SOC. In chapter 7 Bayesian inverse modelling was utilized to estimate the uncertainty of the rate constants of the RothC model. The RothC model was re-programmed and calibrated in a Bayesian context using the “DREAM” algorithm. Once the posterior probability density functions (PDF) for the four (4) rate constants were obtained, they were used to carry out simulations using the entire PDF. Simulated results show the uncertainty created due to uncertainty about the model rate constants. This is an important step since process models such as RothC are widely applied to assess the impact of future climatic scenarios in relation to SOC without any calibration or assessment of uncertainties of the simulations. According to reviewed literature this is the first application of DREAM algorithm in calibration of RothC model rate constants for a catchment scale dataset.

Solos podem ser uma fonte ou um dreno de CO2 atmosférico, dependendo do seu sistema de manejo. Atualmente, o uso do solo e mudança de uso do solo emitem 1,3 ± 0,5 Pg C ano-1, equivalente a 8% das emissões globais. Técnicas como a agricultura de baixa emissão de C têm sido desenvolvidas para sequestrar C nos solos e reduzir a emissão de gases do efeito estufa. Porém, além dos desafios políticos e sociais envolvendo a doção destes sistemas, ainda há muita incerteza sobre o seu real potencial de mitigação. Assim, os objetivos desse estudo foram: i) Quantificar as fontes históricas e atuais de emissão de gases do efeito estufa na região dos Campos Gerais do Paraná, Brasil; ii) quantificar o potencial das melhores práticas de manejo agrícola baseadas nos três pilares da agricultura de conservação: Solo permanentemente coberto, plantio direto e rotação de culturas, em longo prazo (30 anos) para sequestrar carbono no solo, utilizando a fazenda Paiquerê (localizada na região dos Campos Gerais) como um modelo de sucesso; iii) estimar o impacto da adoção das melhores práticas de manejo nas áreas agrícolas da região e globalmente onde adequadas pelos próximos 100 anos utilizando os modelos Century e Roth-C. As fontes de gases do efeito estufa foram apresentadas como um inventário e mostraram que as emissões históricas (1930 – 2017) foram 412,18 Tg C, no qual as mudanças de uso do solo contribuíram com 91% (376,2±130 Tg C). As florestas sequestraram 51.7 ± 23.9 Tg C em 0.6 Mha em 47 anos (1.8 Tg C Mha-1 ano-1) e o plantio direto sequestrou 30.4 ± 23.9 Tg C em 1.9 Mha em 32 anos (0.5 Tg C Mha-1 ano-1). Ambos os modelos tiveram uma boa performance e o modelo Century foi mais eficiente em simular os estoques de carbono do solo, o resíduo médio da simulação foi 10 Mg C ha−1 (13%) para n = 91. O resíduo do modelo aumentou com a quantidade de óxidos no solo, sugerindo que a inclusão do controle mineralógico pode reduzir o viés de simulação. As predições do Century mostraram que o sistema tem potencial para mitigar 13 anos de emissões regionais (330 Tg C em 100 anos) ou 105 anos de emissões do setor agricultura, floresta e pecuária (40 Tg em 100 anos) na região. Da mesma forma, globalmente o sistema apresenta um potencial para sequestrar 2,5 ± 0.02 Pg C na profundidade 0–20 cm e 11,7 ± 3 Pg C na profundidade 0-100 cm em 86 milhões de ha distribuídos por todo o mundo. Este valor é equivalente à 11% das emissões globais dos setores agricultura, floresta e pecuária e mudanças de uso do solo. Assim, a nossa metodologia possa ser utilizada como um modelo para divulgar o potencial da agricultura conservacionista em sequestrar C nos solos e suportar políticas públicas que visem à mitigação das emissões de gases do efeito estufa.
Soils can be a source or sink of atmospheric CO2, according to land use and management. Currently the land use and land use change (LULUC) emits 1.3 ± 0.5 Pg carbon (C) year-1, equivalent to 8% of the global annual emission. Techniques such as low carbon agriculture, has been developed to sequester C in soils and reduce greenhouse gas (GHG) emissions. However, besides political and social challenges for the system adoption, there’s still great uncertainty related to its real mitigation potential. This study aimed: i) Quantify the historical and current main sources of GHG emissions for Campos Gerais region in Paraná state, Brazil; ii) quantify the potential of long term (30 years) agricultural best management practices, based on the three pillars of conservative agriculture: permanent soil cover, crop rotation and no-till, to sequester C in soils, using Paiquerê farm (located in Campos Gerais region) as a successful model; iii) estimate the impact of best management practices adoption in the region croplands and globally for the next 100 years where is suitable using Century and Roth-C models. The GHG emission sources were presented as an inventory and showed that historical (1930 – 2017) GHG emissions in the region was 412.18 Tg C, in which LULUC contributes 91% (376.2±130 Tg C). Forestry sequestered 51.7 ± 23.9 Tg C in 0.6 Mha in 47 years (1.8 Tg C Mha-1 year-1) and no-till sequestered 30.4 ± 23.9 Tg C in 1.9 Mha in 32 years (0.5 Tg C Mha-1 year-1). Both models performed well, and Century was more efficient for simulate the SOC stocks, the mean residue was 10 Mg C ha−1 (13%) for n = 91. The model residue increased along with the oxides content in the soil clay fraction, suggesting that mineralogical control inclusion can reduce the model simulation bias. Century predictions showed that the system currently practiced at Paiquerê farm have the potential to mitigate 13 years of regional total emissions (330 Tg C in 100 years) or 105 years of agriculture, forestry and other land use (AFOLU) sector emissions (40 Tg in 100 years) in the region. In the same way, it has the potential to sequester 2.5±0.02 Pg C at 0-20 cm and 11.7±3 Pg C at 0-100 cm soil depth in 86 million ha globally. This is equivalent to 11% of global annual emissions from LULUC sector. In this way, our methodology can be used as a model to access the potential of conservation agriculture to sequester C and support public policies aiming to mitigate GHG emissions.

Abstract:

Recent work on many problems in additive combinatorics, such as Roth's Theorem, has shown the usefulness of first studying the problem in a finite field environment. Using the techniques of Bourgain to give a result in other settings such as general abelian groups, the author gives a walk through, including proof, of Roth's theorem in both the one dimensional and two dimensional cases (it would be more accurate to refer to the two dimensional case as Shkredov's Theorem). In the one dimensional case the argument is at its base Meshulam's but the structure will be essentially Green's. Let Ϝⁿ [subscript p], p ≠ 2 be the finite field of cardinality N = pⁿ. For large N, any subset A ⊂ Ϝⁿ [subscript p] of cardinality ∣A ∣≳ N ∕ log N must contain a triple of the form {x, x + d, x + 2d} for x, d ∈ Ϝⁿ [subscript p], d ≠ 0. In the two dimensional case the argument is Lacey and McClain who made considerable refinements to this argument of Green who was bringing the argument to the finite field case from a paper of Shkredov. Let Ϝ ⁿ ₂ be the finite field of cardinality N = 2ⁿ. For all large N, any subset A⊂ Ϝⁿ ₂ × Ϝⁿ ₂ of cardinality ∣A ∣≳ N ² (log n) − [superscript epsilon], ε <, 1, must contain a corner {(x, y), (x + d, y), (x, y + d)} for x, y, d ∈ Ϝⁿ₂ and d ≠ 0.

Abstract:

Cette thèse a pour thème central l'étude de deux problèmes soulevés dans les pêcheries modernes, la dégradation des habitats et le manque d'informations, qui comptent parmi les causes les importantes de la surexploitation des ressources halieutiques. Les deux premiers chapitres sont consacrés à l'examen du problème de la dégradation des habitats marins liée notamment aux activités de pêche destructrices. Le modèle de Gordon-Schaefer est prolongé afin de tenir compte de l'impact négatif de la pêche sur les habitats. Les conséquences pour la gestion sont analysées et l'importance de la prise en compte des habitats dans le développement des programmes de gestion des ressources halieutiques est mise en évidence. Le modèle élaboré est ensuite utilisé pour évaluer les bénéfices économiques des récifs artificiels, un outil de gestion auquel font de plus en plus appel les gestionnaires des pêcheries artisanales pour répondre à la dégradation des habitats. Enfin, dans le troisième chapitre, le rôle de l'information pour une pêche durable est examiné lorsque la ressource est en accès libre. Si, dans les deux premiers chapitres, il est supposé que les informations complètes sont disponibles pour l'élaboration des recommandations de gestion, dans la dernière étude, la décision concernant l'exploitation des ressources halieutiques est prise dans un contexte où aucune information sur la ressource n'est accessible. Cette décision est prise individuellement par chaque pêcheur qui opère dans la pêcherie. En développant un modèle multi-agents, nous montrons l'impact de l'apprentissage des pêcheurs sur la dynamique globale du système halieutique
This thesis focuses on two main problems posed in contemporary fisheries: habitat degradation and lack of information. They count among the most important causes of the overexploitation of marine resources. The first two chapters aim at examining the habitat degradation that is linked to destructive fishing activities. The Gordon-Schaefer model is extended to take account of the negative impact of fishing on the habitats. The consequences for fisheries management are analyzed and the importance of taking into account habitats in the development of fisheries management programs is highlighted. Then the extended model is used to evaluate the economic benefits of artificial reefs, a management tool to which frequently resort the managers of small-scale fisheries to mitigate the effects of habitat degradation. Finally, in the third chapter the role of information for sustainable fisheries is examined under open access. If in the first two chapters it is assumed that there is complete information, in the last study this assumption is relaxed - no information on the resource is known. The decision concerning the exploitation of marine resources is made individually by each fisherman that operates in the fishery. By developing an agent-based model, we show the impact of individual learning on the global dynamics of the system

Abstract:

In this thesis, parabolic-pseudoparabolic equations are derived coupling chemical reactions, diffusion, flow and mechanics in a heterogeneous medium using the framework of mixture theory. The weak solvability in 1-D of the obtained models is studied.

For a simpler model formulation, the periodic homogenization in higher space dimensions is performed.
