Texto completoWhile we are observing a decline in insect biodiversity in relation to global changes, some species of crop pests continue to threaten food security worldwide. This is the case for lepidopterans maize stem borers, which pose a major threat to maize production. It is therefore essential to contribute to a better understanding of the impact of global changes and particularly of global warming on maize stem borer populations. Pest responses to global warming can result in contrasting responses depending on the species and trait studied. Among these traits, development rate, i.e. the inverse of development time, is of primary importance given its close dependence to ambient temperature. The development rate quantifies the developmental progression of life stages per unit of time, so that mathematical modeling approaches of the relationship between development rate and temperature can contribute to assess the impact of climate warming on crop pest populations. The objective of this work is to contribute to improve the quantification of the relationship between development rate and temperature by mathematical modeling approaches, and to evaluate the impact of global warming on the development rate of maize stem borers in tropical and temperate climates.Fitting models of developmental rate as a function of temperature to empirical data acquired by rearing individuals at different temperatures has been a widespread method for several decades. Numerous modeling studies have been published, but modeling practices vary considerably within the literature, both in terms of the mathematical models fitted and the experimental protocol, as well as the statistical methods of inference and model selection. In response to this limitation, a study of the influence of experimental protocol on model fitting using a simulation approach, as well as a literature review to establish common and shared modeling and model selection practices were conducted.As a result of global warming, the development time of insect pests could be accelerated or slowed, with impacts to be assessed on pest populations and associated crops. The impacts of different climate warming scenarios on the development time of maize stem borers were evaluated via a mathematical modeling approach for four maize stem borers in temperate and tropical regions. Results show that insect response differs between species and scenarios. This study predicts changes in development time, the magnitude and direction of which depend notably on the optimal temperature for development. While a predominantly shorter development time is expected, the simulations suggest a delay or even a halt for species whose environmental temperature is close to their optimal development temperature. The integration of the non-linear relationship of development rate to temperature thus provides information on future changes in the temporal dynamics of populations. Our analyses indicate that in the absence of mitigating factors such as acclimation, adaptation or dispersal, the developmental time of maize stem borers will be altered, with consequences for their phenology, inter-specific interactions within agro-ecosystems, as well as for maize cultivation and associated crop protection practices

Texto completoOver the last decades, Indonesia has experienced dramatic land transformations with an expansion of oil palm plantations at the expense of tropical forests. Indonesia is currently one of the regions with the highest transformation rate of the land surface worldwide related to the expansion of oil palm plantations and other cash crops replacing forests on large scales. As vegetation is a modifier of the climate near the ground these large-scale land transformations have major impacts on surface biophysical variables such as land surface temperature (LST), albedo, vegetation indices (e.g. the normalized difference vegetation index, NDVI), on the surface energy balance and energy partitioning.Despite the large historic land transformation in Indonesia toward oil palm and other cash crops and governmental plans for future expansion, this is the first study so far to quantify the impacts of land transformation on biophysical variables in Indonesia. To assess such changes at regional scale remote sensing data are needed.As a key driver for many ecological functions, LST is directly affected by land cover changes.We analyze LST from the thermal band of a Landsat image and produce a high-resolution surface temperature map (30 m) for the lowlands of the Jambi province in Sumatra (Indonesia), a region which experienced large land transformation towards oil palm and other cash crops over the past decades. The comparison of LST, albedo, NDVI, and evapotranspiration (ET) between seven different land cover types (forest, urban areas, clear cut land, young and mature oil palm plantations, acacia and rubber plantations) shows that forests have lower surface temperatures than the other land cover types, indicating a local warming effect after forest conversion. LST differences were up to 10.1 ± 2.6 ºC (mean ± SD) between forest and clear-cut land. The differences in surface temperatures are explained by an evaporative cooling effect, which offsets an albedo warming effect.Young and mature oil palm plantations differenced in their biophysical. To study the development of surface biophysical variables during the 20 – 25 years rotation cycle of oil palm plantations, we used three Landsat images from the Jambi province in Sumatra/Indonesia covering a chronosequence of oil palm plantations.Our results show that differences between oil palm plantations in different stages of the oil palm rotation cycle are reflected in differences in the surface energy balance, energy partitioning and biophysical variables. During the oil palm plantation lifecycle the surface temperature differences to forest gradually decrease and approach zero around the mature oil palm plantation stage of 10 years. Concurrently, NDVI increases and the albedo decreases approaching typical values of forests. The surface energy balance and energy partitioning show a development patterns related to biophysical variables and the age of the oil palm plantations. Newly established and young plantations (< 5 years) have less net radiation available than mature oil palm plantations, yet have higher surface temperatures than mature oil palm plantations. The changes in biophysical variables, energy balance and energy partitioning during the oil palm rotation cycle can be explained by the previously identified evaporative cooling effect in which the albedo warming effect is offset. A main determinant in this mechanism is the vegetation cover during the different phases in the oil palm rotation cycle. NDVI as a proxy for vegetation cover showed a consistent inverse relation with the LST of different aged oil palm plantations, a trend that is also observed for different land use types in this study.

Texto completoThis PhD dissertation sets out to analyze, in a socioepistemic way, the various controversies relating to global warming. This work is based on two objectives: (1) to develop and test a reflective analysis tool developed as an ongoing investigation in a single analytical framework articulating existing and occasionally controversial frameworks. (2) To analyze actors' strategies and arguments in the different areas of mediation concerning controversial climate system of knowledge, regarding the understanding to disentangle epistemological and axiological dimensions. This thesis is based on a bibliometric work to build a socio-historical reconstruction of the main controversial elements from the eighteenth century to the present time. Following this epistemological basis the analysis progresses in three steps. The first is an analysis based on a researcher's corpus (climatologists or otherwise) in various situation of communication, secondly completed by inquiry detailed survey with individual and collective interviews and finally a sociolinguistic analysis. Only then does it become possible to provide a radiography of global warming controversies restoring the part we can see, the In and the Off, to unravel the ontological, epistemological and axiological dimensions

Texto completoFocusing on the Economics of Climate Change (ECC), this thesis is a case study in the socio-historical analyzes of scientific fields. It analyses the genesis and institutionalization of this field of research, since its emergence in the mid-1970s. It is based on both quantitative and qualitative methods. Bibliometric analyzes were conducted on a corpus of scientific publications, and were supplemented by interviews and document analysis. By studying the development and structuration of the ECC, we understand to what extent they are consistent with existing analytical frameworks. Then a special focus on issues of interdisciplinarity and expertise allows us to improve our understanding of ECC's dynamics. This study is a prerequisite for further discussion about public and scientific controversies about global warming. Indeed, the public controversy (and researchers who study it) mainly focus on climate science, leaving little room for economic issues. Yet these are crucial in climate policy. Particular attention is given to the agreements and disagreements in ECC. A typology of potential controversies is proposed, followed by two case studies: the controversy over the Stern Review and the one around the model developed by Richard Tol

Texto completoThis thesis proposes a multi-criterion analysis, from which have been displayed the bioclimatic characteristics of the Late-Glacial stadials and interstadials. Mapping data, mainly obtained through crossing three quantification methods, lead to the opposition of distinct paleoclimatic domains in the study area. The relative synchronism of the studied geochronologies highlights the central position of the Northern Atlantic Ocean in the determination of Late-Glacial abrupt climatic changes. However, a review of the main scenarios of oceanographic forcing identifies some of their limitations in the triggering, self-maintenance as well as the teleconnection of the climatic signal. The exploration of other physical mechanisms allows validating the hypothesis by which the air masses’dynamic is an essential component in the forcing of abrupt climatic events. However, the usual theoretical model of atmospheric circulation can not accurately reconstruct the paleoclimatic dynamic of Late-Glacial events. One of the main innovations of this thesis is therefore to experiment a general circulation model, the Mobile Polar High’s one, which provides a comprehensive explanation of climate changes by determining two distinct modes of aerologic circulation (fast and semi-fast). The advantage of this model lies in its ability to analyze a relevant diversity of paleoenvironmental changes in North America and Eurasia during the study period

This analysis allowed us to highlight a clustering behavior of flood according to the climatic region the catchments belong to. Increasing trends have been found on flood magnitude and flood frequency of the 3 sahelian catchments used, and decreasing trends of flood magnitude were found on three sudanian catchments. Finally, the remaining catchments did not showed significant trend in their flood regime

Texto completoThe study of the cryosphere, which is one of the main active component in the global climate system, including global sea level, represents a major interest in the understanding of the current climatic changes. The polar zones are, at the moment, the world areas where the climatic changes appear in a spectacular way, and this reinforces the necessity of a better understanding of the total and surface mass balance of the ice sheets. Indeed, the Antarctic mass balance (surface and total), is not well known yet and is not correctly represented in current climatic models; this matter of fact contributes to strong uncertainties about future climate projection as well as associated potential contribution on sea level change. As a consequence, the continuation of studies on total and surface mass balance (and future change) in the different Antarctic regions, in response to the actual (and future climate), appears essential. In the framework of the present manuscript, I propose to reduce uncertainties in the Antarctic surface mass balance (SMB) estimates, inducing the possibility to optimize the reconstruction of the accumulation parameter over the continent with atmospheric general circulation (climatic) models and interpolation maps of in situ observations
