Sustainable Tourism in Cotacachi Canton, Ecuador

2025 , Álvarez Sánchez, Ana , Camila Terán-Robayo , Nicole Alejandra Revelo-Bossano , Suárez del Villar, Alexis

This study examines the development and perception of sustainable tourism in Cotacachi, a region known for its rich biodiversity and indigenous culture in the province of Imbabura, Ecuador. Despite its potential for ecotourism, our survey results indicate that 66.7% of respondents are unaware of the concept of sustainable tourism and 63.3% have never participated in related activities, highlighting a notable lack of awareness and participation in sustainable practices. The research included a quantitative analysis using online surveys targeting 30 respondents, revealing that only 33.3% are familiar with sustainable tourism. Furthermore, although 50% of participants recognize the importance of these practices, there is a significant discrepancy in the perception of their relevance, suggesting a divide in the understanding and appreciation of sustainable tourism. The results highlight the need for intensive educational programs that not only promote awareness of sustainability but also integrate the community into the planning and benefits of tourism. The sustainable tourism plan proposed in this study seeks to improve the visibility and accessibility of Cotacachi’s natural landscapes, promote the inclusion of indigenous communities in tourism, and strengthen environmental conservation efforts. It is suggested that these efforts could enrich the tourism experience while stimulating local economic development, supporting biodiversity conservation, and reinforcing the region’s cultural identity. Through a holistic approach, the study proposes to transform Cotacachi into a model of sustainable tourism, ensuring long-term benefits for both the community and the environment. The study further revealed that 60% of respondents are aware of Cotacachi’s food fair that connects farmers with merchants, representing a sustainable practice. However, further dissemination and participation in these events is still lacking. For future research, it is recommended to continuously monitor perception and participation in sustainable tourism, in addition to assessing the economic, social, and environmental impact of the proposed interventions. With these measures, Cotacachi can move toward truly sustainable tourism that equitably benefits all stakeholders.

Optimizing the Laboratory Supply Chain with Clarke and Wright Fuzzy Algorithm

2024 , Suárez del Villar, Alexis , Álvarez Sánchez, Ana

The implementation of an optimization strategy in a company dedicated to the sale of laboratory equipment and reagents is detailed. Initially, two routes were established with the objective of significantly reducing delivery times and related costs. These routes were designed using linear programming methods, considering elements such as vehicle carrying capacity, time constraints and customer requirements. After defining the routes, they were incorporated into the company’s operations, adjusting the delivery schedule, and allocating the appropriate resources for the execution of the new logistics plan. In addition, a system was implemented to regularly monitor and control the results, allowing necessary adjustments to be made. The implementation of these measures proved successful, reducing delivery time by 321 min, equivalent to 5.35 h, and saving USD 51.54 per kilometer. This led to a substantial improvement in the company’s logistical efficiency and customer satisfaction. It is recommended to maintain weekly monitoring and control of the implementation, evaluating the results periodically. It is also advisable to regularly check the vehicles used in transportation to ensure their optimal condition and guarantee efficiency and safety in deliveries. The possibility of applying this optimization proposal in other companies in the same sector is raised, given that the positive results obtained could be replicable in similar organizations. In conclusion, the application of this optimization proposal in the laboratory material and reagents company has proven to be extremely effective, reducing delivery times and associated costs, while improving operational efficiency and increasing customer satisfaction.

AN ASSESSMENT OF CUBAN FOOD SECURITY BASED ON THE AGRICULTURAL AREA UNDER CULTIVATION AND AGRICULTURAL YIELDS

2022 , Cosío, E.C. , Suárez del Villar, Alexis , Álvarez Sánchez, Ana , Cruz, I.A.

The research was carried out with official data published in the country, collected from official information sources from 2007 to 2019. In the variables analyzed, the following were considered as having high explanatory power: land distribution, total area, agricultural area, cultivated area, yields of selected crops. For the calculation of the nutritional needs of the population, the nutritional recommendations for the Cuban population were taken into account and the productions were grouped ac-cording to the classification established for the food groups in Cuba. The country’s agricultural area is 6400.18 Mha in 2019, which its use decreases for all the items studied, except for banana, bell pepper, bean, lemon, guava and pump fruit. In addition, yields of the main crops are low, as is the productivity of the livestock sector analyzed. To contribute to the achieve-ment of food security for the Cuban population in correspondence with the standards of the National Institute of Nutrition, an area with technological package (irrigation and optimal yields) of 3942577.82 ha is needed, existing agricultural area in the country; and without technological package (without irrigation), an area of 6424285.82 ha, which are insufficient in 23485 ha. © 2022, University of Cienfuegos, Carlos Rafael Rodriguez.

Exploring Challenges and Strategies for Measuring the Social Impact of Entrepreneurship in Ecuador

2025 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

Research conducted in Ecuador reveals that while 27% of entrepreneurs surveyed identified lack of liquidity as their main challenge, another 23% highlighted low sales as a significant obstacle, and 19% pointed to insecurity. These challenges vary markedly between regions such as Pichincha, Guayas, Manabí and Azuay, which complicates the standardization of methods for measuring the social impact of ventures. Through qualitative interviews and quantitative analysis of INEC data, it was observed that less than 40% of entrepreneurs in Pichincha are trained in impact assessment techniques, which contrasts with the need for training and tools adapted to local contexts. This lack of preparation underlines the urgency of developing customized methodologies that allow entrepreneurs and policy makers to better understand and support the sustainable growth of entrepreneurship in each province. The need for adaptation and customization of measurement tools is evident, particularly in provinces where economic and cultural characteristics vary significantly, e.g. in Azuay, where the artisanal sector is preponderant, it would be beneficial to implement measurement systems that consider cultural and community impacts in addition to economic ones, and collaboration between academia, government and non-governmental organizations can provide vital support in the creation of these methodologies, ensuring that they are robust and relevant. By fostering a stronger environment for social impact measurement, supportive policies could be improved, thus contributing to more equitable economic and social development in Ecuador. This study suggests a clear path towards creating a more effective framework for assessing and maximizing the social impact of ventures, opening up opportunities for future research that delves deeper into the interaction between public policies and entrepreneurial practices in different regional settings.

The Climate in Different Tourist Locations Affecting Children with Bronchial Asthma

2024 , Álvarez Sánchez, Ana , Córdova-Luspa L.E. , Pachacama-Freire M.A.

Tourist destinations are chosen by travelers according to the characteristic climate of each place. These climatic changes, allergen variations, and air pollution contribute to trigger allergens that affect bronchial asthma symptoms. In addition, the increase in temperature and carbon dioxide levels in the atmosphere could lead to a more pronounced production of pollen, which leads to the spread of allergens, increasing sensitization and aggravating allergic reactions in children, especially in those who travel to tourist places such as mountains, beaches, hills, moors, among others. Due to the increasing emission of CO2 and other greenhouse gases, both in developed and developing countries, the negative effects on respiratory health, especially asthma and allergies, are becoming increasingly important, especially in young children and the elderly. Both global climate change and air pollution have a detrimental impact on respiratory health, especially in relation to asthma and various allergic diseases. Importantly, increased emissions of CO2 and various greenhouse gases contribute to climate change, resulting in more extreme and damaging weather events, such as periods of extreme heat, prolonged droughts, severe and devastating thunderstorms, floods, and powerful tropical storms. All these extreme weather events have negative consequences for people with asthma. As a result of the research, it could be corroborated that droughts cause an increase in the concentration of various allergens in the environment, such as pollen and outdoor fungi, which can cause allergic symptoms in sensitive people. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

Strategies to Produce Environmentally Friendly Cleaning Supplies for Tourism in the Galapagos Archipelago

2024 , Álvarez Sánchez, Ana , Suárez del Villar, Alexis

The implementation of disinfectants in the Galapagos Islands requires a meticulous and thoughtful approach, given the ecological sensitivity of this protected area. Disinfectants must be biodegradable and non-toxic to preserve the unique terrestrial and marine biodiversity of the islands. Their effectiveness against a variety of pathogens is critical to protect public health, but this must not compromise the integrity of aquatic and terrestrial ecosystems. Adherence to strict environmental regulations and the provision of clear information on their use are imperative to ensure that their application is both safe and responsible. Maintaining this delicate balance between the protection of human health and the conservation of the unique ecosystem of the Galapagos Islands is crucial, and the disinfectants used play a key role in this effort. The microenterprise under study is dedicated to the manufacture of cleaning products such as disinfectants, liquid soap, and fabric softener for the hotel sector on Santa Cruz Island, Galapagos Archipelago; 8 years ago, due to external factors on the island, the company presented an increase in sales, resulting in inefficiency in the manufacturing process due to lack of capacity, the physical space where it processes was not designed for this business as it is located within the property of the owner of the company, for this reason the 30 m2 that are currently used do not have inventory areas of raw materials, material in process and finished products, which can meet the current demand for production. By using manual processes for the manufacture of the products, the transformation time varies between 1 and 2 days for each reference, which delays delivery times, creating failures that contribute to the non-fulfillment of orders. By diagnosing the mixing and packaging operations that directly influence the failure to deliver products to the final customer, an improvement proposal is made to take advantage of the capacity of the areas [1], reduce waste and minimize the ergonomic risks of the current production line to increase its productivity and satisfy the demand of its customers

Cultural tourism in Ecuador has become a crucial component of the tourism industry, highlighting the country’s heritage, traditions, and vibrant cultural landscapes. This sector allows travelers to deeply immerse themselves in local history, architecture, gastronomy, and customs, thereby enriching not only tourists but also contributing significantly to the local economy and sustainable development. Despite its positive contributions, cultural tourism faces significant challenges. These include overtourism, the commodification of local culture, and the growing socioeconomic inequalities that can arise from unsustainable practices. These issues require careful attention and well-planned strategies to ensure that cultural tourism can continue its development without compromising the country’s cultural and environmental values. To address these challenges, the research used a robust methodological approach that included a comprehensive literature review, statistical data analysis, and detailed case studies. This approach allowed for an in-depth exploration of the opportunities and challenges that shape cultural tourism in Ecuador, assessing how it influences local communities and heritage conservation. The findings of the study highlight the need for a multifaceted strategy that integrates community engagement, policy reforms, and creative marketing tactics. These strategies should aim to maintain the vitality and integrity of cultural tourism, ensuring its viability and the equitable distribution of benefits among all stakeholders involved. Furthermore, it is crucial to implement sustainable tourism practices that not only promote beneficial economic development, but also protect and value Ecuador’s cultural and natural heritage. While cultural tourism in Ecuador offers significant potential for economic and sociocultural development, it is imperative to adopt an integrated and sustainable approach to overcome the challenges and ensure that the benefits of cultural tourism are maximized and distributed in a fair and sustainable manner. This approach will not only benefit current generations but will also leave a valuable legacy for the future, consolidating Ecuador's position as a culturally rich and vibrant tourism destination
