En este trabajo se presenta una reflexión sobre el debate de la minería ilegal en Colombia. Se abordan aspectos tales como el contexto legal e ilegal de la minería, los enfoques narrativos del mismo, los efectos ambientales y la existencia de una meta-narrativa que con supuestos básicos constituyentes contribuya a la solución del problema. Se utilizó un método de análisis de conceptos y criterios, dentro de un enfoque narrativo. El análisis indica que la metanarrativa de la comunidad con los supuestos constituyentes de la diversidad con inadecuación medios-fines y la relación productiva con el medio ambiente internalizando los efectos ambientales, junto con una lógica policontextural y dialógica, pueden ayudar a superar el conflicto entre las diferentes narrativas.

The influence of property, plant and equipment (Fixed Assets) and the quality of infrastructure on return was analyzed in the hospitality industry in emerging markets. The analysis unit was Colombia, a member of the CIVETS emerging market group. Financial healthwas determined by the relationships among return on fixed assets ratio,fixed assets net worth and fixed assets turnover ratios. Besides, the degree of accomplishment of the government plans to improve the quality of infrastructure was considered an indicator of an adequate infrastructure. Transformation by Hénon map equations were applied to data and a recurrence plot, phase space and recurrence quantification analysis were obtained. It was determined the influence of fixed assets net worth and turnoveron the return on fixed assets, and then, the influence of infrastructures on return on fixed assets. A non-linear, non-monotonic relationship existedamongreturn on fixed assets, fixed assets net worth and fixed assets turnover ratios, making investment decision difficult. An adequate development of infrastructure tended to relax the parameters of recurrence, slightly promoting a more steady development of the firms.

AbstractWe here report of a conference about "Pesticides in Soil, Groundwater and Food in Latin America as part of One Health" that took place at the "IV Seminario Internacional de Sanidad Agropecuaria (SISA)" in Varadero, Cuba, 8–12 May 2023. Researchers of Latin America (Argentina, Brazil, Chile, Costa Rica, Colombia, Cuba, Mexico) and Switzerland (workshop initiator) held presentations about occurrence and effects of pesticides on the environment, human health, the replacement of highly hazardous pesticides (HHP) by agroecological alternatives and the agri-food value chain. In a subsequent round table discussion, the presenters identified deficits, needs, interests and opportunities. According to them, the lack of awareness of pesticide use affects the health and safety of workers applying the chemicals. Despite Latin America representing the main agricultural area in the world with a very intense pesticide use, monitoring data of pesticides in soil, surface and groundwaters, food, as well as in humans are missing. Risks of pesticides to humans should be assessed so that authorities can withdraw or limit within "short time" the access to corresponding formulations on the market. Also, communication is not state of the art and should be improved as, e.g. the teaching of workers and farmers, how to correctly use and apply pesticides or the briefing of decision makers. Pollinators suffer from multiple stressors not the least due to pesticides, and alternatives are badly needed. On the technical side, the different analytical methods to determine residues of active ingredients and transformation products in matrices of concern should be harmonized among laboratories.Seven future actions and goals were identified to overcome the above deficits. Next steps after the publishing of this conference report are to harmonize and complete the information status of the presenters by exchanging the results/data already present. Therefore, a platform of interaction to address issues described above and to enhance collaboration shall be created. Samples of different matrices shall be exchanged to harmonize the chemical analysis and establish interlaboratory comparisons. Such activities might be facilitated by joining international associations or organizations, where researchers can offer their expertise, or by forming a new pesticide network for Central and South America that could present tailored projects to national and international organizations and funding agencies.
