Full textIn Peru, despite economic growth of recent years, there is still the problem of low quality of life of a significant percentage of the population that has been generated by poverty. One of the human groups that still has this low quality of life is the small farmers in the high Andean communities of the country. This is the case of the farmers in the district of Frías, a rural district of the Piura highlands, who have shown an economic and social decline, despite the economic and social growth (reflected in the HDI) of Piura is rising in the last 10 years. In that sense, it is necessary to find alternatives that work properly in these areas and complement the income that these people can get from farming, such as tourism. Therefore, the objective of this thesis is to identify a tourism management model that conserves the environment and create jobs and that can be replicated in other areas of Peru with similar characteristics as Frias, in order to contribute to territorial development. Methodology has been based on the guidelines of the Geography of Tourism and qualitative methods such as GIS, interviews, inventory of touristic resources and SWOT (strengths, weaknesses, opportunities and threats), and quantitative methods as the survey and multi-criteria analysis. The procedure was to conduct a preliminary investigation of the characteristics of the district of Frias and to apply workshops to gather information about tourism resources; perception surveys to know the local perception of tourism and interviews with main actors who could develop tourism, as the owner of the local restaurant. After, by using the software ArcGis 10.0, a landscape map was developed and a zoning of tourism resources identified was tested. In addition, the state of the infrastructure that supports tourism as accommodation, restaurants and the roads were evaluated. Finally, with these data, the multi-criteria analysis and SWOT for tourism in the district was made. The result obtained was that the district has 10 tourism resources that are mainly concentrated in its middle sector, sector 2, although the one with a greater extension (Andean Plateau) is in the upper area, sector 4. Of these resources, five have a strong potential to become tourist attractions while three of them show only a moderate potential. Through the analysis it was confirmed that four resources have the potential to be offered as ecotourism products and even one of them as agrotourism product. Also the multi-criteria analysis showed that sector 2 was the zone with more tourism potential in the district. In addition, with the help of GIS and fieldwork, it was identified that the district as a whole has potential to develop agrotourism based on medicinal plants in different areas because they easily grow wild or cultivated in different zones. In the case of the perception survey, this led to the general result that most respondents can be part of adequate human factor for the development of tourism; however, they need information and training in different lines of action of ecotourism and rural tourism. Finally, among the main actors identified to participate in the tourist district management are the population,the municipality, artisans and weavers, farmers, NGO and academic institutions. Tour operators have not been included because this model pursues the self-manage of the population of their resources. In conclusion, the district of Frias has a moderate to strong tourism potential that can be harnessed to generate income for its residents through self-management of resources and infrastructure. In addition, tourism doesn’t compete with other activities in the district, it complements them in the calendar of economic activities. For that reason, the tourist areas in the district of Frías are spaces that should be considered as complementary areas of local economic and territorial development.

Full textAgroforestry systems have been studied by different professionals; Geographers, as they have a macro focus on the territory, incorporate the agrarian landscape or productive landscape approach in order to conserve and develop sustainable economic activities in the Amazonian ecosystems. In the present study, it uses qualitative methods such as participatory agroecological analysis with the purpose of knowing the social and ecological reality of the study area; applies interviews, surveys and workshops with the population. As well as using quantitative and spatial methods such as agroecological modeling using geographic information systems (GIS) with the purpose of determining priority areas to install agroforestry systems with coffee. The results indicate that family gardens (agroforestry systems) generate social and ecological benefits for the population; however, local farmers expect to expand to organic markets, since in the district of Santa Ana, there is potential for sustainable development. Native trees from the district of Santa Ana are proposed as Pino chuncho (Schizolobium amazonicum) and Pacay mono (Inga feuilleei).

Full textAgriculture is the human activity par excellence, which over the years has been adapted to different demands and temporal-spatial contexts. Currently, Peru is a country characterized by activities in the primary sector, including its global export agriculture, though it is also known for its great agrobiodiversity and related gastronomy. Nevertheless, Peru is also a country with very low levels of socio-economic development that is experiencing widespread degradation of its natural resources, in part caused by agricultural activity. This study analyzes the close relationship between agriculture, ecological conservation and gastronomy in four communities in the district of Frias, province of Ayabaca, Piura (Huasipe, El Común, Chaye Grande and Las Pircas), and seeks to propose general guidelines for a sustainable management of the territory. Through surveys based on agroecological methods to farmers (ISSPA), interviews with key actors and residents, social actor mapping, and the use of GIS, it was possible to analyze the territorial development of the district. Results show that the environmental and agricultural problems and weaknesses perceived are also evident in the main failures of the productive systems of the farmers. Deforestation and the water contamination are the two main environmental problems which directly affect agricultural activity in Frias, even though most of the local agricultural practices directly aggravate these problems. On the other hand, thanks to the mapping of social actors, it was possible to demonstrate the importance of creating, maintaining and strengthening the links between social organizations and actors at the institutional and private levels, which is where the majority of environmental and productive projects and initiatives meet with obstacles. Finally, the role of gastronomy is considered as a new lens for the study of territorial dynamics and networks, in order to consider the inherent link between food production and the environment. It is especially important to consider the role and value of this new pillar of development in the current national context in which native crops and local agrobiodiversity are being revalued, and the demand for sustainable agricultural practices and fair-trade chains is spreading.

Full text--- Agriculture is one of the most important economic activities in the world, both because of the income it represents for national economies, and the large number of jobs it creates. But like any human activity, it has exerted strong pressures on natural environments, particularly aquatic environments. This research aims to evaluate the degradation of aquatic environments in the lower Utcubamba River basin (Amazonas, Peru), an area of developing prosperous agricultural activity, using the principles of bioindication, which assesses species distribution of the benthic macroinvertebrate community to help determine environmental changes. Six sampling stations located in the main River and its tributaries were chosen, establishing control zones and study areas. These were evaluated during the wet season (February 2009) and the dry season (September 2009). First, the environmental conditions and water quality were characterized, and then the community structure and metrics of benthic macroinvertebrate community in the study area was analyzed. Clear changes in environmental characteristics (hydrology and environmental integrity) and water quality between the two periods were found, although differences in these environmental characteristics were not recorded between sampling stations. However, community analysis confirmed the existence of differences in species distribution between the time periods and between sampling stations using non-parametric statistical techniques. The Wilcoxon-Mann-Whitney test found temporal differences (p <0.05) in richness and abundance variables, while the ANOSIM analysis found differences in the community structure between the time periods (p <0.05) and between sampling stations (p <0.05). The cluster analysis and ordination nMDS identified two distinct groups at a level of 45% similarity, the first group considered the least degraded formed by the stations E-01, E-02 and E-06 and the second considered the most degraded formed E-03, E-04 and E-05, these results were supported by the findings of the metrics of compositio.

Full text*** The Lesser Rhea, Rhea pennata is a bird of national importance and “critically endangered", with a national distribution restricted to Southern high-Andean ecosystems of Peru. The study on diet to know the biology of the species can be fundamental to conservation programs and or use. For the study of the diet were analyzed feces that were collected in the first national census of 2008, all belonging to the district of Moquegua. The purpose of study, based on the analysis and subsequent identification, was determined the components, plant species and ecology about their foraging habits. Feces analysis was carried out between 2010 and 2012 in the Laboratory of Terrestrial Biogeography and Ecology. From the total of feces were found predominant organic components (Vegetable 96% of volume), and a small percentage of inorganic between them stones that would help the digestion of vegetable material. The structures that were more abundant were leaves with a greater volume of monocots such as Festuca spp, Poa spp., Cyperaceae Indet., Distichia muscoides and remains fruits as Oxychloe andina, Sisyrinchium sp. and Silene sp. The indices of density, weight and volume showed that Oxychloe andina prevails for these indices, and the most frequent species were Oxychloe andina, Onagraceae Indet. and Poa spp. The species with the highest Importance Value Index or IVI were Oxychloe andina, Poa spp., Festuca spp, them all herbaceous and within the monocots group. The diversity index (Shannon-Wiener index H = 2,48) for plants in the diet was higher than similar studies for the diet of this bird, but the niche index (Levins index B’= 0,03) showed a minimum value close to zero indicating a narrow niche breadth, and it would put it in the category of specialist for preferring one species like Oxychloe andina, above different species found, a result which should be complemented with future food availability for a similar time.

Full text(I) La industria publicitaria converge sobre territorios disruptivos y fluctuantes que se transforman continuamente a partir de los cambios digitales de las plataformas, de las redes digitales, de las aplicaciones, del hardware y el software. Todo esto conforma un terreno fértil de innovaciones, de rápida ebullición de novedades, de eclosiones tecnológicas ilimitadas y en constantes tasas de expansión que, a veces, parece imposible medir. En consecuencia, las evoluciones digitales inducen nuevas oportunidades y amenazas para las agencias de publicidad en Internet, estableciendo nuevas narrativas publicitarias digitales; posibilitando modernas construcciones comunicativas e informativas; y facilitando originales estrategias de persuasión publicitaria en los ecosistemas de las marcas. (O) El objetivo prinicpal de la tesis es analizar la información y meta-información de los metamedios de las agencias de publicidad en Internet y en los ecosistemas digitales, para establecer un estado de los portales web y plataformas, de tendencias, estructuras y composiciones técnicas, tecnológicas, comunicativas y publicitarias. (M) Se ha implementado una metodología que combina dos métodos: el método de análisis Découpage interactivo de Cibermedios –sistema de análisis formal para establecer observaciones detalladas de los aspectos que conforman cualquier producto interactivo- y el Sistema Articulado de Análisis de Cibermedios (SAAC) –que es una metodología integral para evaluar neutralmente los distintos componentes de un metamedio-. Ambos permitieron una rigurosa categorización, medición e identificación de los metamedios, ajustados a las necesidades de la industria publicitaria digital. Para la muestra se eligieron los metamedios de agencias de publicidad de siete (7) países: Argentina, Chile, Colombia, España, México, Perú y Estados Unidos. Asimismo, previo a la ejecución metodológica, se realizó una Revisión Sistematizada en la base de datos de SCOPUS de las revistas indexadas en cuartiles del Q1 al Q4, en tres idiomas. (R) Como resultado, se analizaron 147 metamedios de agencias de publicidad en Internet, de siete países en tres dimensiones: los 49 metamedios de mejor posicionamiento en el Ranking Efectividad Effie Index, los 49 metamedios mejor posicionados en SEO de Google y los 49 metamedios más recurrentes que pautaron con SEM de Google, durante los años 2018 y 2019. Se hallaron constantes ausencias, dificultades y conflictos digitales, verificables en categorías de frontend, backend, SEO, SEM, y en variables de herramientas de Google como SERP, SHEMA, My Businnes, Rich Snippet, Brand Knowledge Graph Panel, entre muchas otros. (C) Las conclusiones generales señalan dos grandes líneas: las agencias de publicidad no están adecuadas para las nuevas exigencias de los mercados y de empresas que dominan las formas y métodos de ser visibles de manera digital; y no existen otros modelos metodológicos únicos y exclusivos, desde los campos del saber de la publicidad, que analicen articuladamente los datos, metadatos, información, metainformación y estructuras gráficas, comunicativas y publicitarias de los metamedios de las agencias de publicidad. Del mismo modo, se concluye un común denominador verificable: todos los metamedios de las mejores agencias de publicidad en Internet, en todos los países selecionados y en todas las dimensiones, poseen las mismas ausencias digitales y dificultades en la gestión estratégica del eBranding, o desde las ejecuciones del SEO y el backend, o a partir de las habilidades y tácticas SEM y acciones especiales de posicionamiento corporativo con las herramientas de Google, que influyen en todo el ecosistema digital.
(I) The advertising industry converges on disruptive and fluctuating territories that are continually transformed from the digital changes of platforms, digital networks, applications, hardware and software. All of this forms a fertile ground for innovations, for the rapid boiling of novelties, for unlimited technological hatches and in constant expansion rates that, at times, seem impossible to measure. Consequently, digital evolutions induce new opportunities and threats for Internet advertising agencies, establishing new digital advertising narratives; enabling modern communicative and informative constructions; and facilitating original strategies of advertising persuasion in the ecosystems of the brands. (O) The main objective of the thesis is to analyze the information and meta-information of the metamedia of the advertising agencies on the Internet and in the digital ecosystems, to establish a state of the web portals and platforms, trends, structures and compositions technical, technological, communicative and advertising. (M) A methodology has been implemented that combines two methods: the Cibermedia interactive Découpage analysis method - a formal analysis system to establish detailed observations of the aspects that make up any interactive product - and the Articulated Cybermedia Analysis System (SAAC) -Which is a comprehensive methodology to neutrally evaluate the different components of a metamedium-. Both allowed a rigorous categorization, measurement and identification of metamedia, adjusted to the needs of the digital advertising industry. For the sample, the metamedia of advertising agencies from seven (7) countries were chosen: Argentina, Chile, Colombia, Spain, Mexico, Peru and the United States. Likewise, prior to the methodological execution, a Systematized Review was carried out in the SCOPUS database of the journals indexed in quartiles from Q1 to Q4, in three languages. (R) As a result, 147 metamedia from Internet advertising agencies were analyzed, from seven countries in three dimensions: the 49 metamedia with the best positioning in the Effectiveness Effie Index Ranking, the 49 metamedios with the best SEO positioning of Google and the 49 metamedios The most recurrent ones that were scheduled with Google’s SEM, during the years 2018 and 2019. Constant absences, difficulties and digital conflicts were found, verifiable in frontend, backend, SEO, SEM categories, and in variables of Google tools such as SERP, SHEMA, My Businnes, Rich Snippet, Brand Knowledge Graph Panel, among many others. (C) The general conclusions indicate two main lines: advertising agencies are not suitable for the new demands of markets and companies that dominate the forms and methods of being visible digitally; and there are no other unique and exclusive methodological models, from the fields of advertising knowledge, that jointly analyze the data, metadata, information, meta-information and graphic, communicative and advertising structures of the metamedia of advertising agencies. In the same way, a verifiable common denominator is concluded: all the metamedia of the best advertising agencies on the Internet, in all the selected countries and in all dimensions, have the same digital absences and difficulties in the strategic management of eBranding, or from SEO and backend executions, or from SEM skills and tactics and special corporate positioning actions with Google tools, which influence the entire digital ecosystem.

Full textThe starting point of this research is the first actions towards conservation and reforestation of the fragile ecosystems in Peru. For this, it focuses in Lomas de Atiquipa, located in the Caravelí province, department of Arequipa. The inquiry goes beyond traditional studies by changing the object of study, which is no longer nature in itself but those who act upon nature: the beneficiaries of these interventions. It aims to use social management, participatory, intercultural and human development approaches to analyze the perceptions, knowledges, and actions of the members of Atiquipa Peasant Community over the Lomas de Atiquipa and their first projects for the reforestation of their ecosystem implemented between 2002 and 2012. The research produces knowledge based on the discourse and practices of comuneros, through a qualitative analysis of interviews, life histories, observation and documentation of past and present of Lomas de Atiquipa and the community the hosts this ecosystem. For this, we consider three dimensions: thinking (perceptions, ideas, feelings, beliefs and values), knowing (inherited and acquired knowledges), and doing (practices and experiences). The findings of this research contribute to identify potentials and obstacles in the participation of project beneficiaries in Lomas de Atiquipa, and from there to a better implementation of present and future projects which is one of the main challenges for social management.

Full textHistorically, coastal zones have been intensely occupied; however, in recent decades, anthropic activities have harmed these zones, degrading the ecosystem services they provide. Among these activities, we find beach tourism, considered one of the fastestgrowing tourism areas until before covid-19. Unless tourism is planned, it can cause more damage to the environment and local populations, degrading ecosystems or increasing inequalities. Thus, the objective of this research is to determine the carrying capacity of the tourism activity in El Ñuro to contribute to the basic guidelines for local management to develop sustainable tourism that does not compromise or degrade the marine-coastal natural environment and generates income and improves the quality of life of the local population. Considering the deficient initial planning and the high seasonality influx of tourists, it was expected to find an overcharge in of the touristic areas. The Carrying Capacity is presented as an abstraction of the reality that helps to define the planning of the territory. To estimate the touristic carrying capacity in El Ñuro, the methodology of Cifuentes et al. (1999) was used. To this end, it is necessary to know the details of the tourism activity and, based on this, define correction factors and management capacity. Thanks to this methodology, the overcharge of the touristic areas during the high season is confirmed, although this could also be caused by limited support from local authorities. The most limiting factors correspond to the conflict between tourism with artisanal fishing, and the nesting season of the C. mydas species. The results contribute to decision-making, prioritizing management actions in El Ñuro.

Full textIn the current environmental context, it emerges the need to understand all the possible effects of the increase of the anthropic impact and the “Global Climate Change” on the ecosystems, considered as the main users of services and essential functions upon which whole economic and social textures are based. The forecast study of the ecosystems collides with the high complexity of them and with the lack of integrated observations. The model approach seems to be the most appropriate for the analysis of the complex dynamics of the ecosystems and the contextualization of experimental results and empiric observations. The reductionist-deterministic approach, which generally is used in the implementation of the models, has not been able to reach higher levels of complexity within the structure of the ecosystem. The biotic factor is the component that best describes the complexity of the ecosystem, because of the high dependency upon the other components and their interactions. In this thesis, it is suggested a new stochastic and model approach based on the employment of a naive-Bayesian compiler operating within a fuzzy environment. The combined employment of fuzzy logic and naive-Bayesian approach is useful to process the high degree of uncertainty of the ecosystems. The obtained generative models, called Fuzzy Bayesian Ecological Models (FBEM) are able to modelize the states of the ecosystems as functions of the high number of interactions. FBEM models have been used to understand the environmental risk for the intertidale habitat of sand beaches in case of coast flooding events forecasted from 2010 to 2100. The application has been developed within the EU “Theseus” Project, in which the FBEM models have been used also for a long term simulation and for the computation of the tipping points specific of the habitat depending on flooding events of different intensity.

Full textThe present research consists in the preparation of a Strategic Plan to sustainability of the Peruvian environment in 2027 framed in the sequential model of the strategic process prepared by Dr. Fernando D'Alessio Ipinza. The purpose of this planning is improve the Social Progress Index focused on four pillars of environmental sustainability referring to the ecological footprint, reforested hectares, polluted air in urban areas and treated wastewater. The Social Progress Index of Regional - Peru 2016, registered in 20 regions indexes lower than 45 points which represents a very low level qualification, the rest six regions reach indexes between 46.48 and 53.86 qualified as low level. Referring countries such as Switzerland and Norway with levels higher than 85 points which represents very high levels. The Strategic Plan has established long-term objectives in order to reach a medium high level for the next ten years based on economic, social and environmental care guidelines hopping to be a benchmark in the Latin American and Caribbean region with respect to the Environment care and preservation without affecting the natural resources of future generations. The main purpose is that the population of Peru can have a healthy environment where live, complying with environmental regular law

Full textEl artículo muestra la relevancia de una especie clave —Prosopis pallida— en el desarrollo ecológico del bosque seco costero, y cómo dicha importancia también influye en el desarrollo humano, pues con el tiempo se ha ido fortaleciendo el vínculo social con los ecosistemas forestales. Mediante el método de muestreo por transectos (punto-centro-cuadrado) y el valor obtenido por medio del Índice de Valor de Importancia (IVI) aplicados al Área de Conservación Regional (ACR) Huacrupe La Calera (Olmos, Lambayeque), se corrobora cuán importante es esta especie en el funcionamiento del ecosistema. Por fuentes primarias y recopilación biblio- gráfica, se demuestra su rol en el desarrollo de comunidades en cuanto a sus aportes económicos y culturales en varias zonas de la costa norte desde tiempos antiguos. Esto se superpone con las amenazas y problemas identificados en los bosques en el período de la presente investigación (2014-2015) en cuanto a la sobrevivencia de su vegetación —deforestación, incendios forestales, vulnerabilidad climática, desertificación y fragmentación de hábitat— y cómo repercuten en la población que hace uso de sus recursos.

Full textThis thesis develops research focused on the phenomenon known as start-ups, where Peru has been the scenario of the rapid growth of this type of innovation and how some of them are already reaching international markets. Precisely, the focus of this research is to know more deeply those factors that have managed to facilitate these entrepreneurs entering foreign markets. It is at this point that we seek to know the level of importance that each of these factors represents for start-ups. The research was developed considering different points of view. On one hand, there are experts from the entrepreneurial ecosystem, representatives of public and private institutions that are directly related to start-ups and the development of their ecosystem. On the other hand, we have the entrepreneurs who are the users of all these tools generated in this ecosystem and how that led some of them to achieve internationalization. Based on this approach, it was possible to identify a series of key factors that needed to be validated by the Peruvian start-up population through an opinion poll. This with the objective of identifying the main factors and having a contribution that serves as a guide for those who belong to the ecosystem. To know if there are relations or patterns between the factors and the characteristics of the start-ups, through quantitative methodologies. Finally, the thesis exposes all the obtained results, conclusions, recommendations and even limitations under which the research was developed, contributing in this way with the entrepreneurial ecosystem so that this document serves as a guide for deeper investigations about this phenomenon that it is increasingly important in Peru.

Full textUn ecosistema tecnológico educativo es una comunidad de sistemas d?información que interactúan entre ellos y con otros sistemas externos para dar respuesta a todos los procesos implicados en una institución educativa. La complejidad de l?ecosistema depende de los subsistemas tecnológicos que el composen, de las interacciones que se generan entre ellos y de los propios procesos a los que mujer apoyo. El diseño de un ecosistema tecnológico educativo pasa por la definición de una arquitectura modular que facilite la gobernabilidad del conjunto dando respuesta a todos los procesos implicados. Como resultado de nuestra investigación, hemos definido un modelo teórico para el diseño de ecosistemas tecnológicos educativos basado en trece características, siete estratégicas y seis tecnológicas. Nuestro objetivo es facilitar a los responsables de instituciones educativas un recurso de apoyo a su toma de decisiones en lo que respecta al diseño y evolución de sus ecosistemas tecnológicos educativos. El modelo propuesto es aplicable en diferentes contextos, desde un centro educativo hasta un sistema educativo. El modelo teórico propuesto ha sido validado en el contexto del sistema educativo andorrano a partir de la realización de un trabajo de campo que ha contado con la participación de diferentes agentes (profesorado, equipos directivos, responsables TIC y equipo del Ministerio).
A technological educational ecosystem is the community of information systems that interact with each other and with external ones in order to answer to all the processes involved in an educational institution. It may be viewed as a complex system whose level of complexity depends on the technological subsystems, the interactions generated between them, and the processes supported by the ecosystem. In order to design it, we must think about an ecosystem’s architecture that must allow an eficient governance. As a result of our research, we propose a series of attributes that a technological educational ecosystem must possess in order to provide an efficient and sustainable response to all the strategic, fundamental and support procedures involved in every process associated with an educational institution. Our main objective is to present educationalists responsible for designing a technological ecosystem with resources in the form of thirteen characteristics that should be satisfied in order to enable the ecosystem to be deployed successfully. Our proposed model is scalable as it can be applied to different scenarios with different dimensions, from a regional or national educational system to a school or university. This theoretical model has been implemented successfully in the context of Andorra’s national educational system. Once the technological ecosystem has been deployed we have asked the diferent stakeholders (Government, directors, teachers and IT staff) about their level of agreement with the different characteristics involved in the design. The results show a very high level of agreement with the model.

Aquesta tesi té per objectiu principal avaluar l'ús potencial dels paràmetres de fluorescència de la chl-a com a biomarcadors de toxicitat per metalls, i trobar relacions causa-efecte entre l’exposició dels metalls, altres factors ambientals (ex. la llum), i les respostes funcionals i estructurals del biofilms. Aquesta tesi demostra que els paràmetres de fluorescència de la chl-a permeten detectar alteracions ràpides del biofilm causades per la toxicitat del zinc, tan al laboratori com en rius contaminats. En microcosmos, els paràmetres de fluorescència de la chl-a permeten avaluar canvis estructurals en l’aparell fotosintètic i en la composició dels grups algals dels biofilms exposats crònicament al zinc. Per avaluar els efectes de la contaminació crònica per metalls en rius es recomana fer experiments de translocació de biofilms i utilitzar una aproximació de multi-biomarcador.
