Texto completo da fonteThe textile industry is the most polluting of all industrial sectors. This sector is not only a large consumer of water, but it also discharges enormous quantities of wastewater loaded with salts, dyes, detergents, heavy metals, degradable organic materials, stabilizing agents, etc. The discharge of this water presents risks for hydro-ecosystems, soil, and plants. In addition to the harmful effects of untreated textile effluent on the environment, there is the problem of water scarcity which is becoming increasingly serious. the high demand for water in the agricultural sector, and the lack of fodder in some countries around the world such as Tunisia. In this sense, several processes have been developed to treat textile effluents such as chemical oxidation, chemical coagulation, biodegradation, adsorption, and membrane processes. However, few studies have focused on the impact of irrigation with these treated effluents on soils and plants.The objective of this thesis is the reuse of treated textile effluent (TTE) using scenarios of agricultural valorization of these waters. This work consists of submitting biological treatment (TB) effluents from a Tunisian textile factory to additional treatments by ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO). Given that TB effluents are characterized by high salinity, a coupling scenario was considered by mixing 50/50 (V: V) biological treatment water (TB) with well water (S) (TB/S) and NF waters (TB/NF). The impact of irrigation with these waters on the physicochemical and biological parameters of the soil and on the growth, mineral composition, and absorption of MTE in a forage plant: Sesbania bispinosa was evaluated. A physicochemical characterization of irrigation water was carried out with an evaluation of the genotoxic potential of soils irrigated by TTE.The results indicate that the quality of TTE is not stable over time and varies according to the production processes. TB does not meet the requirements of the NT 106.03 standard relating to the reuse of wastewater in agriculture. These waters are characterized by high pH, EC, and Na+, Cl- and SO42- contents. Although NF and RO membranes effectively reduce salinity and the contents of these elements and do not present any risk to the soil and plants with the absence of genotoxic effect of soils on plants, these techniques produce more concentrated water discharges. Consequently, the coupling of TB water with well water constitutes the best alternative for agricultural valorization. This coupling made it possible to reduce the salinity of TB water by reducing the contents of chemical elements such as Na+, Cl-, and SO42-. The reuse of this water for agricultural purposes did not show negative effects on the growth and mineral nutrition of S.bispinosa, did not present risks on the physico-chemical quality of the soil, and contributed to an improvement in enzymatic activity in the soil. Therefore, water coupling constitutes a valorization option. It is a simple and inexpensive solution which, on the one hand, makes it possible to overcome the lack of water and, on the other hand, reduces the quantities of water released into the environment by the textile industries

Texto completo da fonteMany problems with nitrate and pesticide contamination from agriculture exist in European drinking water catchments. In France, a new mitigation approach aims at preventing water quality degradation in explicitly targeting agricultural non-point source pollutions associated with leaching of nitrates and pesticides. This work aims at assessing the opportunity to develop organic farming in water catchment areas in order to reduce nitrate and pesticide leaching from root zone. The objective was to analyze both i) feasibility of conversions to organic farming on farms concerned by water preservation and ii) the potential impacts of these conversions in terms of nitrate and pesticide leaching reduction.To explore the potential contribution of organic farming in water catchment areas, we develop an innovative typology approach to characterize farmers’ conceptions and strategies related to cropping systems’ organization on the farm territory. Our method was tested in two French water catchment areas characterized by diversified production systems, where semi-structured interviews were carried out with conventional and organic farmers. Resulting typologies of farmers were used to assess leaching risks variability related with current cropping systems and to identify potential similarities between conventional and organic farmers’ conceptions. Nitrate and pesticide leaching risks for cropping systems were assessed and spatialized by using four agro-environmental indicators. Our results show major variations for all indicators at both study sites, for example N-surpluses which range from -105 to 192 kg N ha-1 year-1. These variations are deeply related with diversity of farmers’ conceptions summarized in typologies. To assess proximity of conventional farmers to organic farming, we used typologies to compare conceptions related to organization of cropping systems between conventional and organic farmers. By analyzing specificities of organic farmers’ conceptions, we determined three main criteria of proximity to organic farming; these criteria were then used to identify various degrees of proximity to organic farming among conventional farmers in the catchment areas.To assess potential contribution of organic farming to water preservation in catchment areas, we firstly compared nitrate leaching risks between conventional and organic cropping systems. Our results reveal low leaching risks from organic systems, characterized by reduced N-surpluses and lower bare soils frequencies in autumn. According to these results, massive development of organic farming should decrease nitrate leaching in our two water catchment areas. However, analysis of similarities between conventional and organic farmers’ conceptions shows that a majority of farmers are characterized by a low level of proximity to organic farming. Moreover, the farmers who show strongest similarities with organic farmers’ conceptions are already those with low leaching risks cropping systems. To significantly lower nitrate leaching risks, conversions should concern conventional farmers with low degree of proximity to organic farming

Texto completo da fonteSmall-scale private operators, informal water vendors, non-state providers… new stakeholders are participating in water supply governance in developing cities. Previously ignored, they are today drawing growing attention from the international community as they question the governance modalities of network industries in the Global South. Heterogeneous and composite, of local origin, adapted to the demands of end-users, alternative services would be highly flexible, thus adapted to the particular environment of developing cities. They also would be able to provide new funds and to ensure sustainability of water supply services in long or shorter term. However, there is little theoretical research in economics undertaken on this topic. We are confirming this through an unpublished bibliometric analysis. This PhD aims consequently to provide theoretical and empirical elements to fill this gap. Adopting a critical stance, it intends to highlight the postulates and unconfirmed efficiency assumptions of this particular governance structure. Thereafter, it mobilizes New Institutional Economics concepts, offering an original analytical framework on the determinants and efficiency of alternatives services. Through an extensive field survey conducted in Cambodia, we criticize the competitive character of this type of governance which is a priori supposed to ground it. We show the impact of transaction costs on the organizational arrangements related to the conditions of water resource access. Beyond the rhetoric of private sector efficiency, we also stress the importance to take into account non-sectoral organizational arrangements. We finally underline the key role of informal norms in reducing the uncertainties of the institutional environment. We nevertheless conclude on the potential difficulties to institutionalize this(hose) governance(s) structure(s) as they are locked in an institutional path-dependence

Texto completo da fonteAbstract Promoted as the most efficient irrigation technology, able to contribute to solving the major current water crises, drip irrigation spreads quickly throughout the world. The perspective of an idealized technology with a theoretical efficiency studied in experimental stations without users struck us immediately. Rejecting a normative view of drip irrigation (what it should be/do), we studied it in practice, interacting with a multitude of actors focusing on what it does and for whom. Our objective is to analyse how the practice of this technical innovation has changed the technology and the socio-professional pathways of different actors involved in drip irrigation, and analyse the impact on actual irrigation efficiencies. We show how local actors took control of the innovation taking responsibility in spheres once thought reserved for engineers in the production, use and dissemination of innovation. These local initiatives crossed and strengthened state development programs promoting drip irrigation. The technology attracted a large number of non-conventional actors who changed the technology, but also changed themselves. The successful diffusion of drip irrigation ensures their socio-professional promotion, and they in turn will attract more users to the world of drip irrigation. This constitutes the strength of drip irrigation, which is a technical object around which powerful socio-technical networks were built. Bricolage helped design systems better suited to local conditions, but was also a learning process to incorporate change. From an imported technology accessible to a minority of large farmers, a plurality of drip systems is now accessible for a wide diversity of farmers. Finally, the performance of irrigation systems is heterogeneous, some farmers irrigating 3-4 times the volume necessary for crop water requirements. This performance can be explained by irrigation practices favouring a water comfort to crops, reflecting the logic of the actors. Today, "water saving" is an unattainable goal, as it is not a priority for any of the actors, including the state. We conclude that it would be interesting to engage non-conventional actors as allies in order to promote the concept of water saving on the field with users

Texto completo da fonteUntil today, there has been little interest of international Law concerning the earth’s subsurface, as the space that extends from the surface of the soil or of the seabed to the center of the earth. On the one hand, there is no rule of international law that regulates the use Sovereign States have of their territorial subsurface. It is currently understood that subsburface activities and property law that regulates them, are within domestic jurisdiction only and do not come under international law scrutinity as they waive the exercice of an absolute independance of States. On the other hand, the existing rules of international law that regulates extraterritorial subsurface, notably the seabed and ocean floor and subsoil thereof beyond national jurisdiction and the Antarctic, consider the earth’s subsurface mostly in terms of use and exploitation of mineral resources. Faced with the evergrowing uses of the subsurface that are solely used for extraction or for injection and storing, and regarding the impacts of some underground activities on the environment and on human rights, International Law must play a role by regulating the content and extent of rights that are exercised over the earth’s subsurface inside and outside territorial jurisdiction for development and protection purposes
