Anise-based drink, “Bolegancho”, production represents an economic source of livelihood for families; however, its artisanal production does not comply with environmental regulations. A multidisciplinary analysis at the social, geographical, and environmental levels of “Bolegancho” production is carried out. In the first part, surveys were applied to producers, determining that they are in a socioeconomic stratum 1 and 2, where the majority are dedicated to production in their homes and not to distribution. Subsequently, the production areas were geo-referenced for the collection of water and soil samples. For the environmental component, physicochemical and microbiological tests were carried out on the “Bolegancho” and the water used to produce it, identifying the lack of sanitation and the effects on the final product; on the other hand, the results that are poured into the soil according to the analyses may be beneficial for crops due to their organic matter content. Regarding the air, microbiological tests determined the presence of different types of bacteria and fungi causing alterations in the environment, which implies that the distillation processes of the “Bolegancho” should be studied from a multidisciplinary perspective.

The water quality of the “La Brava” creek, in Ocaña Norte de Santander, was analyzed using physicochemical and biological parameters to determine quality indices. Three sampling sections were established throughout the study area, taking samples in duplicate every four months for each point during a year; characterization of each sample was done following the protocols of standard methods. The information obtained was analyzed through water quality and contamination indices, determining that the water quality of the micro-basin is moderate, and its level of contamination is low; remaining in good homogeneous condition along the entire area. The utilization of a systems of indices allows for a good approach to assess the conditions of the basin, establishing that, currently, anthropic activities have minimal effect on the water resource in the study area. It is important to highlight that, although the level of contamination is low, it is necessary to generate strategies that guarantee the continuous quality and water supply in the area.

In Colombia, the increasing use of motorcycles as an informal conveyance has emerge as a means of labor survival for people with limited resources. Mototaxism has rapidly become the main means of transport in the spatial structure of the city of Ocaña; however, high emission rates may present an environmental problem. The study and implementation of strategies for the mitigation of greenhouse gas, is of great help for the reduction of the emissions of these gases. Environmental control of vehicles in Colombia is carried out through an annual technical-mechanical and gas inspection, which seeks to control the emission of pollutant gases from vehicles; however, electrochemical gas sensors may provide an accurate and convenient alternative, as it can be implemented as an analytic tool in gas monitoring and control systems allowing different approaches for the control of vehicle exhaust emissions. A development board such as Arduino can be programmed with an algorithm that utilizes a combination of sensors and connectivity modules, constituting a microcontroller unit that is able to achieve successful monitoring over emission gases, one such algorithm is proposed by the authors.
