    Active and passive treatments are used as a cost effective option to treat acid mine drainage (AMD) through the use of physical, chemical or microbiological processes. These drainages are characterized by being highly acidic, in addition to presenting high concentrations of heavy metals that are toxic to the environment and living beings. The purpose of this study is the removal of metals and the neutralization of acidity of AMD obtained from Santa Rosa, El Oro province, for which this process will be validated through the design, assembly and operation of a continuous operation pilot plant, which involves physicochemical processes, it consists of the initial reactor where neutralization, aeration and coagulation take place, followed by the settler where the sludge is retained and finally, the sand/limestone filter. The average removal percentages were 100 percent iron, 99.94 percent copper, 100 percent arsenic, 94.06 percent cadmium, 99.66 percent manganese, 95.73 percent aluminum, and a final pH of 8.42, fulfilling all the parameters with the limits established for its release. The sulfate was not removed, however, it is below the maximum permissible limit for its release. From the results obtained, it is possible to demonstrate the effectiveness and importance of the assembly and operation of a pilot plant for the removal of metals and neutralization of acidity present in the acid drainage of mines in Santa Rosa, El Oro province.

    This research project is focused on the analysis of the country's situation in terms of food policy, finding negative factors that have been carried over from previous years and have not been able to be reduced or eradicated despite the development of various projects. The main objective is to provide relevant information on food policy within the framework of food security, availability and sovereignty, the programs and proposals that have been carried out to eradicate the problems, and a comparison in relation to other countries. It is intended to know more fully the problems of malnutrition, poverty and food insecurity, and how it affects the population of the country and which are the most vulnerable groups. The aforementioned is described after a compilation of information after 2018, both nationally and internationally.
