Participatory mapping is a tool for community work linked to natural resource management. It is an auxiliary for diagnosis and data acquisition from communities and their natural resources. In Baja California, there are several indigenous communities, some close to urban areas but still unknown to most people in cities as well as visitors. These communities are fighting to restore and maintain their language, tradition, territory, biological, and cultural diversity. This work was carried out by linking members of the indigenous community of San Jose de la Zorra with bachelor’s and graduate degree students, to obtain information on the biological, cultural, and economic activities of the community through participatory mapping. The learning experience was significant for all participants; although it was not the intention in this study, students had the unique opportunity to exchange information and learn culture and biodiversity from indigenous people. The indigenous community was involved in field data acquisition and the use of some information and communication technology resources developed for this approach, and used it for natural resource management and decision making. The main results of this experience were wide format printed maps that were placed on several sites inside and outside the community, digital mapping that gave information about natural, cultural, and economic resources of the community for local and foreign visitors, and technology transference to solve problems identified by the community.
Introduction. In recent years, the Government of Baja California has promoted not to discharge wastewater with high content of fats and oils. A company in the region dedicated to the collection of sludge, installed a horizontal centrifugation system for the extraction of oil, generating a sludge with 5% fat and oil. The result of this process is sent to a process of biodigestion and vermicompost for the generation of solid and liquid humus, which generates wastewater with high organic load that require a treatment before disposal. Objective. Develop an experimental prototype of electroflocculation to wastewater treatment with a high content of organic matter. Methodology was divided into 4 stages: 1) Physicochemical and biological characterization of the wastewater; 2) Assembly of the electroflocculation prototype; 3) Experimental assessment 4) Verification of system operation. Contribution. Through the elaboration of the prototype, the effectiveness of the electroflocculation process was confirmed for the wastewater treatment (WT) with a high content of organic matter (OM) and pathogenic bacteria, since a greater than 50% decrease of the biochemical oxygen demand (BOD5), chemical demand of oxygen (COD), fecal coliforms and Salmonella.
Morelos Park is part of the Municipal System of Tijuana Theme Parks (SIMPATT). Due to the multiple activities carried out for the community, as well as the lack of maintenance to the electrical installation, among other factors, the cost for electricity consumption is around $ 1,022,107.00 M.N. yearly. Objective: the purpose of this project is to carry out an energy efficiency study to obtain energy performance indicators (KPI) with which improvements for the rational and efficient use of energy can be proposed. Methodology: the project was worked with the collaboration of students in renewable energy engineering program internship. The study includes the following stages: 1) gathering energy data to determine the current state of electrical energy consumption; 2) analysis of the information obtained inorder to detect improvement areas; and 3) proposals for an efficient use of electrical energy. Contribution: with the development of this study, in addition to providing a viable economic benefit to the park administration, it contributes to the integration and application of tools and knowledge of future engineers in real environment situations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
