Abstract:
Quinoa is a highly diverse crop domesticated in the Andean region of South America with broad adaptation to a wide range of marginal environments. Quinoa has garnered interest worldwide due to its nutritional and health benefits. Over the last decade, quinoa production has expanded outside of the Andean region, prompting multiple studies investigating the potential for quinoa cultivation in novel environments. Currently, quinoa is grown in countries spanning five continents, including North America, Europe, Asia, Africa, and Oceania. Here, we update the advances of quinoa research in Ecuador across different topics, including (a) current quinoa production situation with a focus on breeding progress, (b) traditional seed production, and (c) the impact of the work of the nongovernment organization “European Committee for Training and Agriculture” with quinoa farmers in Chimborazo province. Additionally, we discuss genetic diversity, primary pests and diseases, actions for adapting quinoa to tropical areas, and recent innovations in quinoa processing in Ecuador. Finally, we report a case study describing a participatory breeding project between Washington State University and the Association of Andean Seed and Nutritional Food Producers Mushuk Yuyay in the province of Cañar.

Abstract:
Objective: The aim of this study was to determine the methyl esters fatty acids (FAMEs) profile of quinoa seeds (Chenopodium quinoa Willd) of a sample cultivated in Guaranda, Ecuador.Methods: Quinoa oil was obtained from quinoa seeds using the Soxhlet method. FAMEs identification and quantification were carried out using the gas chromatography (GC) with a mass spectrometry (MS), using the database Library NIST14.L to identify the fatty acids present in quinoa oil.Results: Quinoa oil from Ecuador was analyzed by GC-MS, to obtain four majoritarian fatty acids, palmitic acid (10.66%), oleic acid (24.70%), linoleic acid (62.47%), and linolenic acid (2.19%). Omega 6 was the most abundant fatty acid in quinoa oil. Quinoa oil has a good proportion of oleic acid and linoleic acid.Conclusions: Quinoa seeds present a good proportion of fatty acids. These seeds can be used in the food industry for different purposes to enjoy their fatty acids composition. Regular consumption of quinoa can improve health.

Abstract:
Quinoa (Chenopodium quinoa) is an important export of the Andean region, and its key disease is quinoa downy mildew, caused by Peronospora variabilis. P. variabilis oospores can be seedborne and rapid methods to detect seedborne P. variabilis have not been developed. In this research, a polymerase chain reaction (PCR)-based detection method was developed to detect seedborne P. variabilis and a sequencing-based method was used to validate the PCR-based method. P. variabilis was detected in 31 of 33 quinoa seed lots using the PCR-based method and in 32 of 33 quinoa seed lots using the sequencing-based method. Thirty-one of the quinoa seed lots tested in this study were sold for human consumption, with seed originating from six different countries. Internal transcribed spacer (ITS) and cytochrome c oxidase subunit 2 (COX2) phylogenies were examined to determine whether geographical differences occurred in P. variabilis populations originating from Ecuador, Bolivia, and the United States. No geographical differences were observed in the ITS-derived phylogeny but the COX2 phylogeny indicated that geographical differences existed between U.S. and South American samples. Both ITS and COX2 phylogenies supported the existence of a Peronospora sp., distinct from P. variabilis, that causes systemic-like downy mildew symptoms on quinoa in Ecuador. The results of these studies allow for a better understanding of P. variabilis populations in South America and identified a new causal agent for quinoa downy mildew. The PCR-based seed detection method allows for the development of P. variabilis-free quinoa seed, which may prove important for management of quinoa downy mildew.

Abstract:
The quinoa downy mildew is one of the major diseases affecting quinoa in Ecuador. Considering the lack of standardized methods to quantify this disease on leaves, the aim of this study was to develop a standard area diagram to quantify the severity of the quinoa downy mildew. To standardize the assessment, we developed two sets of standard area diagrams. To validate the diagram, twelve raters estimated the severity of 50 scanned leaf images at different severity levels. The proposed diagram with linear increments provided good levels of accuracy and precision, constituting thus a useful tool in epidemiological studies and for the development of strategies to control the quinoa downy mildew.

Abstract:
¿Cuál es el camino que lleva a la quinoa a ser consumida por un mundo globalizado? En este artículo se revisan diversos documentos con la finalidad de responder a esta pregunta. La quinoa pasa por un proceso de resignificación diferente al de otros alimentos que son vistos como marcadores étnicos, por ejemplo la máchica o el chocho. La quinoa no precisa despojarse del marcador étnico indígena para ser valorada, más bien se apropia de dicho marcador y lo utiliza; es decir, se conforma en un alimento “políticamente correcto” para el momento específico en el que vivimos. Estudio sobre el proceso histórico por el que pasó la quinoa, específicamente en el Ecuador, así como en la región andina, para convertirse en un alimento reconocido a nivel global, por sus cualidades, ancestrales y puras, respaldadas por puntos nutricionales y organolépticos.

Abstract:
En los Valles Interandinos del Ecuador entre 2000 y 3000 m.s.n.m se tienen bajos rendimientos de quinua con alto riesgo por la variabilidad del clima y la siembra de variedades criollas con inadecuadas prácticas de manejo. La investigación determinó las cantidades de nutrientes extraídos por tres variedades de quinua (Chenopodium quinoa Willd), durante el desarrollo del cultivo. El objetivo fue determinar las cantidades de nitrógeno, fósforo, potasio, calcio y magnesio que la planta de quinua extrae durante su ciclo de vida. Se evaluaron tres variedades de quinua, se determinó la cantidad de materia seca, porcentaje de nutrientes en estudio y cantidad de nutriente en kg ha-1 de las muestras tomadas en hojas, tallos y panículas a los 20, 40, 60, 80, 100 y 120 días después de la siembra. Los resultados obtenidos indican que la variedad Imbaya con la dosis 150-80-40 de N, P, K mostro una mayor cantidad de materia seca acumulada en la planta total con 9870 kg ha-1 a los 120 días después de la siembra (dds). Los nutrientes más absorbidos por la planta de quinua fueron K y N seguido de Ca, Mg y P en este orden. Los índices de cosecha (IC) obtenidos fueron: N=0,63; P=0,64; K= 0,55; Ca=0,52 y Mg=0,65. La aplicación del fertilizante en el cultivo de quinua se debe realizar en tres épocas: en la siembra, a la deshierba a los 30 días y al aporque a los 50 días de edad del cultivo.

Abstract:
Quinoa (Chenopodium quinoaWilld.) is a staple food crop for millions of impoverished rural inhabitants of Andean South America where it has been cultivated for millennia. Interest in quinoa, due largely to its superior nutritional characteristics, is fuelling a growing export market and has led to an increased focus on genetic research and the development of quinoa breeding programmes throughout South America. The success of these breeding programmes will rely heavily on the development of core germplasm collections and germplasm conservation. We report the development of a set of fluorescence-tagged microsatellite molecular markers that can be used to characterize genetic diversity within quinoa germplasm and we use this set of 36 microsatellites markers to genetically characterize the diversity of 121 accessions ofC. quinoaheld in the USDA germplasm bank, 22 accessions from the CIP-FAO international nursery collection and eight accessions representing parents from genetic mapping populations. A total of 420 alleles were detected among the quinoa accessions with an average of 11 alleles detected per microsatellite locus. Genetic heterogeneity was observed in 32% of the quinoa accessions at a given locus and suggests that many of these accessions represent heterogeneous seed lots or landraces. Both unweighted pair-group method with arithmetic averages (UPGMA) and principle components analysis (PCA) analyses partitioned the quinoa accessions into two main clusters. The first major cluster consisted of accessions from the Andean highlands of Peru, Bolivia, Ecuador, Argentina and extreme northeastern Chile. The other main cluster contained accessions from both the lowlands of Chile and a set of USDA accessions with no known passport data, collected by Emigdio Ballón. Using the patterns of genetic diversity detected within theC. quinoaaccessions we discuss hypotheses regarding quinoa's centre of diversity, including highland and lowland ecotype clustering patterns, origin of lowland varieties, origin of domestication, and diversity levels in the USDA and CIP-FAO collections.

Abstract:
SUMMARYQuinoa cultivation in Chile presents an ancient and active complex of geographic, climatic, social and cultural interactions that has determined its current biodiversity in the three main growing zones (north, central and south). Importantly, these interactions involve the participation of farmers, whose activities are at the base of seed exchange networks due to their knowledge andin situconservation of genetic diversity. The present study reports how a better understanding of farmers’ seed exchanges and local production practices could impact the genetic structure and diversity of quinoa at national scale in Chile. Using field interviews and characterization of 20 microsatellite genetic markers in a multi-origin set of 34 quinoa accessions representative of Chile and the South American region, the phenetic analysis of germplasm was consistent with the current classification of quinoa ecotypes present in Chile and Andean zone. This allowed the identification of five populations, which were represented by quinoa of Salares (northern Chile), Coastal/Lowlands (central and southern Chile), Highlands (Peru, Bolivia and Argentina) and Inter-Andean Valleys (Ecuador and Colombia). The highly informative quality of the markers used revealed a wide genetic diversity among main growing areas in Chile, which correlated well with natural geographical–edaphic–climatic and social–linguistic context to the expansion of quinoa biodiversity. Additionally, in addition to ancient seed exchanges, this process is still governed by the diverse agricultural practices of Andean farmers. Genetic erosion is considered an imminent risk due to small-scale farming, where the influence of increased migration of people to urban systems and export-driven changes to the agro-ecosystems may further reduce the diversity of quinoa plants in cultivation.

Abstract:
La quinua (Chenopodium quinoa Willd.) se ha cultivado principalmente en la cordillera de los Andes en Bolivia, Perú, Ecuador y Colombia, fue uno de los principales alimentos de los pueblos andinos preincaicos e incaicos. Las bondades de la quinua radican en su alto valor nutricional por su contenido de proteína y su gran plasticidad fenotípica. La presente investigación se realizó en la Finca Experimental “La María” de la Universidad Técnica Estatal de Quevedo, ubicada en la provincia de Los Ríos. El objetivo del trabajo fue analizar las características agronómicas de los genotipos de quinua en condiciones ambientales de la costa central. Se aplicó un diseño completamente al azar con veintiún tratamientos (genotipos) y tres repeticiones. Las variables agronómicas evaluadas mostraron diferencias estadísticas significativas (p<0.05). En la variable altura de planta destacó el genotipo 48 con 154.17 cm a los 90 días. Por otra parte, en la determinación de días a la cosecha el genotipo más tardío fue el genotipo RGG con 143 días, mientras el genotipo más precoz fue el 42 con 90 días a la cosecha. En la variable peso de 1,000 semillas los resultados alcanzados demostraron que el genotipo Faro 2 destacó ligeramente con un registro de 2.58 g. Finalmente, en cuanto al rendimiento por planta (g) el mayor registro lo obtuvo el genotipo O-5 con 143.15 g planta-1. Los datos registrados en las distintas variables demuestran viabilidad en la producción de quinua y debido a su amplia adaptabilidad, la convierten en una valiosa alternativa de diversificación para la costa ecuatoriana.

Abstract:
A cross-sectional study with repeated measures was conducted in the Ecuadorian Highlands to determine whether quinoa (Chenopodium quinoa) production was associated with improved nutrition among women. Agricultural production systems, income, socio-economic status, morbidity, diet and protein-energy status were compared between a group of quinoa-producers and a randomly sampled quasi-control group of non-quinoa-producers (total n = 90 households) over four study rounds (pre- and post-quinoa-harvest).
Seasonal and age-related variability in nutrient intakes as well as anthropometric status provided evidence of nutritional vulnerability in this population. Post-menopausal women (50+ years of age) consumed less energy (300 calories), less protein (11 g) and maintained a lower mean body weight (3.66 kg) compared to their younger counterparts. Seasonal changes in dietary quality and anthropometric status were apparent for women of all ages with less protein and micronutrients consumed post-harvest and mean arm circumference 6 cm smaller. Marked prevalences of inadequate intakes of many of these same nutrients (including iron, niacin, and vitamin B12) were demonstrated with the Probability Method.
Correlates of diet quantity (energy), quality (animal protein adjusted for energy) and anthropometric status were established. By means of a Principal Components analysis, socio-economic status was shown to be comprised of two unique constructs: modern lifestyle and farming wealth. Both factors were related to diet quality but neither was related to diet quantity. Diet quality, in turn, was significantly related to anthropometric status in multivariate models.
Women in quinoa-producing households consumed higher amounts of most nutrients and maintained larger arm protein-energy stores than those in non-quinoa-producing families. Trends were similar in children with no evidence of a difference in anthropometric status. However, quinoa-producers scored higher on both scales of socio-economic status, demonstrating self-selection bias. In multivariate models, quinoa production was related to increased intakes of energy, iron, zinc and folate but effects on animal protein intake and anthropometric status were confounded by the socio-economic effects. Therefore, while quinoa production was associated with positive nutritional impacts, the most impoverished households were left virtually untouched by this agricultural opportunity.

Abstract:
This thesis explores the Quijos Valley ground stone economy in relation to broader social, political, and economic aspects of the Quijos chiefdoms during the Late Period (AD 500 – 1500). In particular, this research examines the extent to which ground stone craft production was a dimension of social differentiation during a period marked by the greatest sociopolitical transformations. Ultimately, this research suggests that Late Period ground stone production was an independent and part-time household activity, and not an avenue of elite aggrandizement. However, aspects of this research have aimed to show that certain forms of ground stone were important implements of household maintenance, both socially and economically. This research is embedded within the Quijos Valley Regional Archaeological Project (QVRAP) and has aimed to contribute to our understanding of the development of social complexity within this region, as well as contributing to our understanding of ground stone craft production more generally.

Abstract:
This thesis critically examines the role of indigeneity in urban policies and planning in a context of constitutional changes that have taken place in Bolivia and Ecuador in the recent decade. It departs from previous academic and policy research which mainly studied indigenous rights in rural areas and focused on urban indigenous peoples as outlawed, excluded, or insurgent subjects. Instead, it conceptualises the translation of indigenous rights into urban policies as a complex process in which a multiplicity of social actors – including government officials and urban indigenous groups – are involved. Drawing on the practice-centric literature on urban policy and planning, it recognises that the work of government officials is influenced by multiple factors such as constitutional texts as well as their personal views, interest group demands, and the wider structural and political environment surrounding them. Government attempts to translate indigenous rights are contrasted to urban indigenous peoples’ own understandings of indigeneity and associated interests and demands. In addition, this thesis uses an asset accumulation framework as well as the concept of tactics to identify how urban indigenous peoples address and negotiate their interests and demands and try to influence decision-making processes from the bottom-up. The thesis relies on La Paz (Bolivia) and Quito (Ecuador) as ‘illustrative cases’ to study the role of indigeneity in urban policies. As both La Paz and Quito represent capital cities, it was possible to approach government officials operating at multiple scales – international, national and local – as well as ordinary urban indigenous residents. Methodologically, the thesis employs a qualitative, case study comparison and draws on information derived from semi-structured interviews, document analysis, participant observation and participatory focus groups conducted during eleven months of fieldwork. In terms of comparison, this thesis makes use of a variation-finding approach. By explaining variations between the cases through focusing on the unique processes and factors that shaped the translation of indigenous rights within each city, it intends to offer a more nuanced and context-responsive approach for studying urban indigeneity and addressing indigenous rights in cities. A central finding of this thesis is that the incorporation of indigeneity into urban policies and indigenous people’s own practices to fulfil their specific demands were characterised by a set of conflicting realities: First, for government officials the translation of indigenous rights into urban policies sometimes clashed with other priorities – such as addressing universal rights and interests of non-indigenous pressure groups – or with their own views of the city as a ‘white’, ‘western’, and ‘modern’ places. Second, urban indigenous peoples articulated multiple and contradictory identities. They mainly did this by voicing specific demands for land – an important asset which they associated with the preservation of a communal and traditional lifestyle but also with aspirations to lead a modern and capitalist life in the city. Third, the findings reveal that indigenous peoples – particularly their community leaders – had to enter in negotiations with governments to access different assets such as land, housing, or education. In these processes leaders manoeuvred between different worlds. They had to conform to political agendas and – particularly in the case of Bolivia – to official spatialized understandings of identity and rights which often conflicted with their own sense of being indigenous in the city.

Full text
Abstract:
This thesis explores the processes through which scarcity is constructed in informal settlements and how conditions emerging within its limits gives way to particular socio-spatial phenomena and influence the emergence of self-organisation and creative strategies from a non-expert perspective. At the same time, this thesis deconstructs these emerging tactics (reactive and transformative) in a diagrammatic way to generate a critical study of their potential for socio-spatial change that goes beyond the everyday survival. Most people associate scarcity with “not having enough” of something, most usually of a material nature. In contrast, this paper is based on the premise that scarcity is a constructed condition, therefore exploring it beyond its immediate manifestation and illustrating its discursive, distributive and socio-material components. In this line, the research uses Assemblage Theory as both an approach and a tool for analysis. This approach allows the research to depart from everyday narratives of the residents, and gradually evolve into a multi-scalar, non-linear reading of scarcity, by following leads into different realms and unpacking a series of routine events to uncover their connections to wider processes and particular elements affecting the settlement and the city as a whole. For this purpose, the research is based on a qualitative, flexible and multi-sited methodology, using different case studies as testing grounds. Collected data stems from a 11-months ethnographic fieldwork in informal settlements in Ecuador and Kenya, analysing the socio-spatial practices and strategies deployed by the different actors producing the built environment and arising from everyday and latent experiences of scarcity. The thesis examines the multi-scalar nature of these strategies, including self-building and management tactics, the mobilisation of grassroots organisations, the innovative ways of collaborating deployed by different coalitions and the reformulation of urban development policies. As outcomes of the research, the thesis will show illustrative diagrams that allow a better understanding of, firstly, the construction of scarcity in the built environment beyond its immediate manifestation and secondly, the way that emerging tactics a) improve existing conditions of scarcity, b) reinforce the status quo or c) contribute to the worsening of the original condition. Therefore, this thesis aims to offer lessons with both practical and theoretical considerations, by firstly, giving an insight into the complexity and transcalar nature of the construction of scarcity in informal settlements; secondly, by illustrating how acute conditions related to scarcity gives birth to a plethora of particular phenomena shaping the territory, social relationships and processes; and thirdly, by identifying specific characteristics within the informal that might allow for new readings of the city and possibilities for socio-spatial change under conditions of scarcity.

Abstract:
On February 25, 2009, OCP Ecuador S.A. faced its first major incident; an oil spill consisting of 11,700 barrels of heavy crude oil in an area of high biodiversity in eastern Ecuador. An earth movement caused stress in the pipeline that resulted in its breakage. The temporarily impacted area covered 30 hectares of soil and gravel along 180 kilometers of three rivers that form the high watershed of the Amazon River; these rivers are the Santa Rosa, Quijos and the Coca. A paper describing the model implemented to manage the emergency, clean up and remediation activities was presented during the 2010 International Pipeline Conference. Now, 3 years later, this paper presents the final conclusions and lessons learned once the remediation, approval process and subsequent monitoring have been completed.

Abstract:
Because of the growth of cities in size and population, people get used to perform several stage trips involving transfers due to advantages such as time or price paid, being multistage trips more attractive compared to single stage trips. In Quito, Ecuador, nowadays multistage trips represent one third of total daily trips. This paper seeks to identify main characteristics of multistage trips as well as find relationships and inferences that allow recommendations regarding best practices to policy makers and transport managers. The information used belong to the data collected in the Household Survey Mobility held in Quito in 2011. Based on these data, the present work starts using an analysis with descriptive statistics. The next phase of this research involves the search for a methodology in order to identify correlations between demographic, socioeconomic and transport variables related with traveler´s choice for making or not a transfer. Best methodology found was the use of Binary Logistic Regression (Logit) and specific computer software, with which different statistic's models were performed to find the strongest correlation. The paper ends with conclusions and recommendations as well as suggestions for future research.DOI: http://dx.doi.org/10.4995/CIT2016.2016.3530

Abstract:
The present article provides an operational energy comparison of modern concrete and foamed geopolymers as envelope materials for single unit housing in Ecuador. The study is performed by replacing the concrete material used in the walls and roof elements with foamed geopolymer components. Residential building sector requires around 35.6% of the total energy demand in Ecuador. For this reason, efforts on building practices improvement are relevant for the Ecuadorian society. The foamed geopolymers are a mixture of aluminosilicate material obtained from Ecuadorian natural zeolite, group of alkaline activators and the foamed agent that when mixing the raw materials and obtain the geopolymer. To assess the potential use of foamed geopolymers as construction material, the annual energy demand for a social interest dwelling was obtained through simulation with EnergyPlus. Prefabricated Insulated Concrete Forms was established as the construction practice for the building model. Annual energy simulations were performed considering two Ecuadorian representative weathers, to Guayaquil and Quito locations. Material properties of foamed geopolymers ware acquired by own experimental facilities. Thermal conductivity was obtained with the use of the hot plate method, while specific heat by means of differential scanning calorimetry (DSC) analysis. This analysis uses foamed geopolymers obtained from two procedures. Thus, these proposed materials presented low density, low thermal conductivity, and acceptable compressive strength values. Finally, an assessment of natural geopolymers as a concrete replacement is presented, including a thermal characterization, and a sustainable construction evaluation. The findings affirm the key role of material selection in construction practices. Reductions around 4.0% in annual electricity demand was achieved for Guayaquil case, while energy consumption decreases around 1.3% for Quito.
