The relocation of Chongqing Iron and Steel Company (CIS) in 2011 resulted in its old site’s demolition in 2012. As one of the largest post-industrial sites in Chongqing, it faces many future challenges. Framed by an existing redevelopment plan, this practicum proposes a design that responds to the current site conditions and lays groundwork for its future. The design capitalizes on the existing attributes of the site to create a variety of experiences. It employs phytotehcnologies to remediate contaminated soil and also offers opportunities for research, education and recreation. Personal experiences and reflections on China’s post-industrial regeneration are also discussed. / October 2016

The experiment was installed at the Rafael Fernandes Experimental Farm of the Universidade Federal Rural do Semiárido (UFERSA) in a wide Y system, spaced 3m x 2m, with a drip irrigation system, with three rootstocks and two canopy cultivars, for a period of 2 years. A randomized block design was used in a 3 x 2 factorial scheme, with three rootstock cultivars (IAC 313 `Tropical ', IAC 572' Jales' and IAC 766` Campinas) and two canopy cultivars ('Italy improved' and 'Isabel precocious'), with five plants per portion, organized into six treatments and six replicates. With the sequence of the prunings and harvests the results of three cycles of 'Isabel precocious' production and two of 'Improved Italy' were obtained. After a period necessary to guarantee better plant vigor, a new cycle was organized for the collection and analysis of productivity data. Data were submitted to analysis of variance (F test) at the 0.01 and 0.05 significance levels, and the means were compared by the Tukey test, at a 5% rate probability, using the SAS / STAT Software ( SAS Institute, 2012). Because it is a non-traditional region for grapevine cultivation, we opted for the study of phenology in the production process, the effects of climate through bioclimatic indicators, such as day degrees (GD) and heliothermal index of Geslin (IHG) , and the analysis of the quality of the fruit during its development (PC: bunch weight, CC: bunch length, DC: bunch diameter, NB: number of berries, PB: berry weight, CB: berry length, DB : berry diameter) and post-harvest (Soluble Solids-SS, Titratable Total Acid-ATT and SS / ATT ratio). The obtained results led us to conclude that in the climatic conditions of the Potiguar semi-arid region the production of table grapes, 'Italy improved ' and 'Isabel precocious' cultivars finds favorable environment for commercial production, producing grapes of good quality for the market, independent of the types of rootstock tested / O presente estudo foi desenvolvido na perspectiva de recomendar plantios comerciais com cultivares de uvas de mesa para região não tradicional na viticultura, como no Semiárido Potiguar, e teve como o objetivo, avaliar aspectos produtivos e fenológicos das cultivares 'Itália melhorada' e 'Isabel precoce', em diferentes tipos de porta-enxertos. O experimento foi instalado na Fazenda Experimental Rafael Fernandes da Universidade Federal Rural do Semiárido (UFERSA) em sistema de Y aberto (“wide Y”), no espaçamento de 3m x 2 m, com sistema de irrigação por gotejamento, com três porta-enxertos e duas cultivares copa, por um período de 2 anos. O delineamento usado foi o de Blocos Casualizados, num esquema fatorial de 3 x2, sendo três cultivares porta-enxerto (IAC 313 `Tropical'; IAC 572 ‘Jales’ e IAC 766 `Campinas) e duas cultivares copa ('Itália melhorada' e 'Isabel precoce'), com cinco plantas por parcela, organizados em seis tratamentos e seis repetições. Com a sequência das podas e colheitas foram obtidos resultados de três ciclos de produção da 'Isabel precoce' e dois da 'Itália melhorada'. Após um período necessário para garantia de melhor vigor das plantas, foi organizado um novo ciclo para a coleta e análise de dados de produtividade. Os dados foram submetidos à análise de variância (teste F) nos níveis de 0,01 e 0,05 de significância, e as médias comparadas pelo teste de Tukey, a 5% de probabilidade, por meio do programa computacional SAS/STAT Software (SAS Institute, 2012). Por se tratar de uma região não tradicional para o cultivo de videiras, optou-se pelo estudo da fenologia no processo produtivo, os efeitos do clima por meio dos indicadores bioclimáticos, como os graus dias (GD) e índice heliotérmico de Geslin (IHG), e a análise da qualidade do fruto durante o seu desenvolvimento (PC: peso do cacho; CC: comprimento do cacho; DC: diâmetro do cacho; NB: número de bagas; PB: peso de baga; CB: comprimento da baga; DB: diâmetro da baga) e pós-colheita (Sólidos Solúveis-SS, Acidez Titulável Total- ATT e a relação SS/ATT). Os resultados obtidos levaram a concluir que nas condições do clima do Semiárido Potiguar a produção de uva de mesa, das cultivares 'Itália melhorada' e 'Isabel precoce', encontra ambiente favorável à produção comercial, produzindo uvas de boa qualidade para o mercado, independente dos tipos de porta-enxertos testados / 2017-09-01

Au cours des dernières décennies, un type de marais filtrant, généralement planté de saules, a été développé pour opérer un système de traitement d’eau sans effluent, par évapotranspiration. Ces marais à effluent sont généralement utilisés pour le traitement d’eau usée domestique, mais pourraient aussi présenter une alternative intéressante pour d’autres applications, comme le traitement de lixiviat contaminé. Les guides de conception actuellement disponibles ne permettent toutefois pas de concevoir un système flexible qui permettrait de gérer les grandes variations de volume à traiter liées à la nature même des lixiviats (i.e. résultent entièrement des précipitations) et ne tiennent pas compte de la variation inter et intra-annuelle de l’évapotranspiration (ET) du saule. Cette thèse présente d’abord une revue de littérature de ET du genre Salix et de ses facteurs de variation les plus importants. Il apparaît que les conditions de croissance ont plus d’importance que l’identité spécifique et que la disponibilité en eau, la fertilisation et la contamination sont les principaux facteurs dictant l’ET des saules. L’effet de l’âge, du contexte expérimental, de la densité de plant et du type de sol n’a pas pu être clairement démontrés par cette revue. Ensuite, une étude portant sur le potentiel d’ET de S. miyabeana ‘SX67’ est présentée. Il est démontré qu’un modèle basé sur des paramètres foliaires et sur le déficit de pression de vapeur d’eau dans l’air permet de prédire l’ET de S. miyabeana en condition de marais filtrant. Cette étude permettra entre autres d’améliorer les plans de conception d’un éventuel marais de saules à effluent nul. Pour continuer, la réponse de S. miyabeana ‘SX67’ à différentes concentrations de lixiviat et à différents types de substrats a été étudiée. Ce cultivar s’est montré tolérant aux concentrations du lixiviat brut retrouvées sur un site d’entreposage de poteaux de bois traité. Le type de substrat a influencé la réponse du saule et ses performances écophysiologiques, en plus d’affecter la dynamique des contaminants. Finalement, la modélisation hydrologique d’un système à effluent nul par marais de saules permet de proposer une méthode de dimensionnement des différents compartiments du système pour atteindre un objectif d’effluent nul sur une période de 20 ans, ainsi que de proposer des solutions de conception et d’opération optimale. L’application du modèle au cas spécifique d’un site d’entreposage de poteaux de bois traité a permis d’évaluer la faisabilité, d’un point de vue hydrologique, de cette technologie dans le contexte climatique du sud du Québec. Sur la base de cette étude, la principale limite pour l’application des marais à effluent nul au Québec sont la surface de marais et le volume de stockage requis. Dans le cas où une étape de prétraitement efficace précède le marais de saule, la durée de vie du marais ne devrait pas être limitante et dépendra principalement de la durée de vie des végétaux. Cependant, le destin des contaminants dans le système, qu’il s’agisse de la disposition des contaminants accumulés à l’étape de prétraitement ou d’une éventuelle translocation de contaminants dans les parties aériennes des végétaux, devrait être considéré avant d’établir un système à effluent nul. Les résultats de cette recherche permettent, entre autres, de proposer les marais de saules à effluent nul comme une alternative intéressante pour le traitement d’eau contaminée au Québec. / During the last decades, a type of constructed wetlands, usually planted with willows, was developed to operate a water treatment system with zero effluent, by evapotranspiration. These zero liquid discharge wetlands are typically used for domestic wastewater treatment, but could also be an attractive alternative for other applications, such as contaminated leachate treatment. However, the design guidelines currently available do not allow for the design of a flexible system that would manage the large variations of volume to be treated related to the very nature of leachates (i.e. produced entirely from precipitation) and do not take into account inter and intra-annual variation of willows evapotranspiration (ET). This thesis first presents a literature review of ET for the genus Salix and its most important driving factors. It appears that growing conditions are more important than species identity and that water availability, fertilization and contamination are the main factors dictating ET in willow. The effect of age, experimental context, planting density, and soil type could not be clearly demonstrated by this review. Then, a study on the potential ET of S. miyabeana 'SX67' is presented. It is shown that a model based on foliar parameters and on the water vapor pressure deficit in the air makes it possible to predict the ET of S. miyabeana under wetland conditions. This study will, among other things, improve the design plans for a potential zero effluent willow wetland. To continue, the response of S. miyabeana 'SX67' to different leachate concentrations and different types of substrates was studied. This cultivar has been tolerant of raw leachate concentrations found at a treated wood pole storage site. The type of substrate influenced the willow response and ecophysiological performance, and affected the dynamics of the contaminants. Finally, the hydrological modelling of a system with zero effluent by willow bed makes it possible to propose a method of dimensioning for the different compartments of the system in order to reach a zero effluent objective over a period of 20 years, as well as to propose solutions for optimal design and operation. The application of the model to the specific case of a treated wood pole storage site made it possible to assess the hydrological feasibility of this technology in the climate context of southern Quebec. On the basis of this study, the main limit for the application of zero effluent willow bed in Quebec is the wetland area and the storage volume required. In the case where an effective pre-treatment step precedes the willow bed, the life of the wetland should not be limiting and will depend mainly on the lifespan of the plants. However, the fate of the contaminants in the system, be it the disposition of the accumulated contaminants at the pre-treatment stage or a possible translocation of contaminants into the aerial parts of the plants, should be considered before establishing a system with zero effluent. The results of this research make it possible, among other things, to propose zero-effluent willow wetlands as an interesting alternative for the treatment of contaminated water in Quebec.
