Full textThis Ph.D. thesis is part of the MAISEO project associating partners among them: the CACG, managing the water supply of several watersheds located in the south west of France, the Meteo-France center and the CESBIO. One of the goals is to develop innovative and operational tools to estimate crops' water needs at the territory scale. The aim is to provide managers tools to better manage the water supplies linked to the predominant crop encountered in south west of France: maize. The objective of the thesis was to estimate the yield and water requirements of maize crop over large areas. For this purpose, we used an agro-meteorological model coupled to optical satellite imagery. Numerous high spatial and temporal resolution images from different sensors have been used, prefiguring the arrival of the Sentinel-2 data launched in 2015. The first part was to combine remote sensing data with the SAFY (Simple Algorithm For Yield estimates) crop model (Duchemin et al., 2008a) that simulates plant development based on Monteith theory (Monteith, 1972) in order to accurately estimate maize biomass and yield. Numerous field data have been used for the validation at local scale. At regional scale, the results have been aggregated and compared to Agreste yield statistics provided by the French government. Results led us to propose a new formulation of the SAFY model taking into account the temporal variation of the effective light use efficiency (ELUE) and of the specific leaf area (SLA). This modification allows a better simulation of the crop growth dynamics and an improvement of yield estimates at the local and regional scale. Furthermore, we changed the calibration method in order to limit the use of in situ data that are difficult to access over large areas. We also highlighted the contribution of the double logistic function, used to interpolate the NDVI time series. This interpolation enables an accurate determination of the crop growing season and it allows constraining some model parameters such as the emergence date. The SAFY model constrained by remote sensing data is able to well reproduce the yield for the two departments without taking into account the evolution of the soil water storage (Battude et al., 2016)

Full textThe study explores the feasibility to estimate the corn field production and its water needs during the irrigation period. The work, validated in the South-West of France, is based on an agro-meteorological model coupled with satellite imagery to extend monitoring to regional scale. The recent availability of Sentinel-1 radar mission allows monitoring without atmospheric constraints (e.g. clouds) as opposed to optical acquisitions. The estimation of production is linked with dry biomass (ear, plant) and yield data at the field scale. Beyond new improvements, the combination of optical and radar provides accurate results and even improves the estimations based on optical by filling the gaps caused by cloud cover at the beginning of the season. The water needs simulation are more contrasted as a result of the accuracy of the input data. Moreover, some features (e.g. soil properties) can be seen within soil moisture measurements, even though they cannot be modeled

Full textKorea repeatedly experiences floods and droughts that cause traumatic environmental conditions with huge economic impact. With an approach and solution such as Smart Water Grid these problems can be alleviated. Tapping into the retention ponds behind dams, rainfall harvest facilities in urban areas and any other structures installed to store rainfall water during flood events will mitigate the damage of flooding and provide a new source of national water resources. Similarly, purified waste water, ground water and desalinated sea water can also be feasible to use as alternative water resources. In this research, the water balance assessment model is being developed as a Smart Water Grid concept. In fact, large proportions of water resources in Korea rely on a river fresh water. Also in the Youngjongdo Island, tap water from water purification plant which use original source from the Han river. However the water supply system in the island is quite dangerous since the water purification plant is located in Incheon city and the water comes to island through the sea and no other source is used in the island. Therefore, once the accident at main water pipe in the sea, no water is available in this island. Information on water availability and water needs are crucial to identify hot spots of quantitative pressures on water resources. In this study, all available alternative water sources are calculated by the model developed through this study. Several physical and stochastic models on hydraulic and hydrological approaches are nominated to investigate physical characteristics of catchments

Full textThe basin of Niari is the only rural region in Congo to be thought of as welcoming. It has good quality lands, an important density of population, nevertheless there is a noticeable vacant part of surfaces suitable for cultivation. There, we can find mist farm-pastoral concessions and farm-produce industries. It’s therefore a region with a lot of natural advantages showing its agricultural vocation. But, because of a pluviometry that satisfies only a part of the needs of the population and agriculture in water, and because of a potential excessive evapo-transpiration, there is a problem of relative deficiency in water. When in fact, the presence of many water courses running between 28 an 804 m3 rate of flows, drilling flows going up to 91,8 m3 hour, even 133,3 m3 per hour, and source flows reaching 1800 l s value; this presence shows that the Niari basin has considerable water resources the exploitation of which could satisfy all the needs. The aim of study is, to show how physical and climatic factors influence the reconstitution of resources, to analyse modes and conditions of water supping, and to encourage decision-makers to undertake actions aiming to improve these modes and conditions of supplying. Whereas in rural environment, this deficiency in water is linked, in particular, to a shortage and irregularity of rain, and to the harshness of the dry season, and to the distance of water spots the access of which is difficult

Full textSelenium is an antioxidant and an oligo-element for animals and humans. However, the concentration range between deficiency and toxicity is particularly narrow. This metalloid allotropic is introduced indirectly in the food chain via its accumulation in food plants. The literature on this subject is still restricted and incompleted, and traditionally realised on model plants and in presence of selenium in high concentrations. This thesis is about selenium transfer in a plant crop, Zea mays, and consequences of this accumulation on physiological plant through essential cations accumulation study (calcium, magnesium, iron, zinc, manganese, copper). For this, experiments in a controlled atmosphere chamber (hydroponic conditions) were performed to obtain samples then analyzed by appropriate analytical and sensitive techniques (HPLC, CRC-ICP-MS, ICP-OES or AAS-GF). Various factors influencing selenium transfer in plants have been studied: concentration and form of selenium source and stage of plant development. The results of this study showed that root absorption, concentration within the plants and their tissues, degree of selenium metabolization and volatilization, and therefore selenium intake in animals and humans, are strongly influenced by those three factors. Furthermore, this study showed that accumulation and distribution of cations within the plants depend on selenium -mainly at high concentrations. These effects may be associated with the system imbalance of reactive oxygen species detoxification in plant cells, consistent with the ambivalent nature of selenium mentioned in the literature: antioxidant or prooxidant depending on its concentration

Full textCorn stover is the aerial part of the plant excluding grain, sometimes called MOG (material other than grain). Stover is generally a crop residue because most grain growers leave it on the ground after grain harvest. Dry corn stover can be used as bedding material or as a solid fuel on the farm. However, the cold and wet climate prevailing in Eastern Canada considerably limits the harvest of dry corn stover (moisture content < 15%) in the fall. Standing corn plants were sampled in fall 2008 to 2010 in order to determine the potential stover yields. For a site located in a 2300-2500 CHU (crop heat unit) zone, stover yields varied from 6.2 to 8.0 tonnes of dry matter (DM) per hectare. Yields ranging from 7.7 to 10.5 t DM ha-1 were measured for two other sites located in the 2900-3100 CHU zone. Large scale field harvest trials were done in spring from 2009 to 2011. The available stover yield in the spring averaged 63% (6.6 t DM ha-1) of the stover yield in the previous fall. Based on fall yields, 47 to 50% of the stover was collected using haymaking equipment. The average moisture content was 9.0%. Collection efficiency was reduced to 45% with a flail windrower but a gain in productivity was measured (5.2 ha h-1) compared to mowing and raking operations (2.3 and 2.0 ha h-1). Harvest losses from a self-loading wagon were smaller (6%) than from a round baler (15%). The cost of field operations varied between $29.04 and $34.30 t-1 DM depending on the harvest sequence. Storage cost was as high as $71.85 t-1 DM for bulk material harvested with the self-loading wagon. Large square and round bale storage cost was estimated at $29.87 t-1 DM and $59.44 t-1 DM, respectively. Corn stover had a higher absorption index (2.8) than wood shavings (1.8) and saw dust (2.1) used at the farm. The calorific energy of corn stover ranged from 16.86 to 17.64 MJ kg-1 while the ash content varied between 4.80 and 7.31%. Results should allow effective planning of cost and operations related to dry corn stover harvested in the spring.
