The purpose of the study was to describe the analytical bioevaluation of the predictive model of science in aquatic ecotoxicology. From the Sciencedirect website, 18 scientific reviews, 72 scientific articles, six encyclopedias and 32 book chapters corresponding to 11 scientific journals were analyzed. Two descriptors were proposed: 1st) of the field conditions which referred to the natural development of organisms and, 2nd) of the laboratory conditions where three types of tests were considered: A) potential of toxicity, B) of growth and, C) transformation. Although, the advantage of field conditions is the disadvantage in laboratory conditions, it is essential that bio-assessments are combined for ecosystem services to be sustainable in society. From various bioevaluations of field and laboratory conditions, data that have statistical significance and its argumentation constitute new p...

Advanced strategies for the design of clean technologies are characterized by reducing waste emissions, reducing their generation at the source itself and implementing measures to reduce water consumption, recover material and energy resources through recycling and integration of processes and an adequate selection of raw materials. Along with this, emphasis has been placed on the development of effective environmental management practices. [1] The design of clean processes is based on the use of classical engineering tools, to conceive a production scheme that considers both technical-economic and environmental aspects. These objectives are compatible, since the environmental impact can, in part, be reduced by increasing the overall productivity of the process. In many cases, modifications with low capital requirements have led to significant increases in productivity and a reduction in...

The research was carried out in the Tingo María National Park and aimed to identify the determinants of the economic value of ecotourism, generated by “Cueva de las Lechuzas”. In order to verify the hypothesis that the socioeconomic aspects and the choice of the environmental services of visitors influence the economic value of ecotourism, a survey was carried out. A binary-choice microeconometric model was estimated, to determine the convenience of entry payment to the tourist attraction, achieving to establish that both socioeconomic aspects and environmental services influence the intention of payment. Regarding the characteristics of environmental services choice, it was found that the main reason to visit to this important resource, corresponds to the invitation of a friend and / or family member who previously visited the area. Regarding the destination of the visit, most resp...

The Environmental Kuznets Curve (EKC) is widely used to examine the relationship between economic growth and environmental degradation. However, its empirical application critically depends on the selection of appropriate indicators. This article presents a methodological critique of the article «Peru's Environmental Kuznets Curve 2010-2020: A Departmental View» written by Erazo-Camacho et al. (2024), which employs average temperature as a proxy for environmental degradation in an econometric model applied to Peru. It is argued that this choice introduces methodological biases that undermine the validity of its conclusions, particularly the claim that an increase in per capita GDP reduces regional temperatures. This conclusion contradicts established scientific literature (IPCC, 2023), which links fossil fuel-based economic growth and extractive expansion to increased greenhouse gas (G...

The genotype by environment interaction (IGA) is the main limitation to select the best genotypes for different environments. The objective of this study was to use the additive main effects and multiplicative interaction (AMMI) model to evaluate the IGA of 25 varieties of starchy maize. The information was generated in four trials established in contrasting environments in the province of Tayacaja, Peru, in the 2019-2020 crop cycle. The 5x5 alpha lattice design was used, with three replications, where the experimental units consisted of two rows 4 m long, with spatial arrangements of 0.80 m between rows and 0.20 m between planting points. The IGA was measured through the grain yield, adjusted to 15% humidity. Once the importance of the IGA in the experiments was verified, the multivariate analysis was carried out, to obtain the singular values of the AMMI terms that were significa...

The Puyango-Tumbes river basin derives from the polluting sources located basically in its upper and middle part, which incorporate a considerable amount of heavy metals into the water and, to a greater extent, into the sediments. The main activities that generate pollutants and incorporate them into the Puyango-Tumbes river are mining in the towns of Portovelo and Zaruma in the province of El Oro, Ecuador, as well as the generation and discharge of solid waste and residual water from the towns. seated in the river. This situation has already generated some problems in the lower part of the basin, a Peruvian sector, where it contaminates the rice soils on the left bank of the Tumbes river and the Tumbes mangroves; damaging direct food sources of the population and putting human health at risk. Within the framework of the aforementioned, this project aims to classify environmental indicat...

In an era of environmental influence and the search for social solutions with a sustainable approach, the municipal authorities rehearse economic options with an environmental approach that contribute to the solution of the problems that affect their cities. One of them is the Municipal Solid Waste Management. The objective of the present investigation was to demonstrate which management mod- el-public, private or mixed- for the management of municipally managed solid waste is financially and environmentally sustainable over time. The methodology applied was exploratory and explanatory. It is said to be exploratory because in Peru there are no investigations with these variables and it is explanatory because it is a causal investigation that analyzed the solid waste management models at the municipal level. The results of the research show that mixed management for the management o...

The natural world was always considered a model of connective, coherent, and projective knowledge. Did the specialization fragmented and disarticulated this harmonic and integral structure? Currently, while facing a world that has become so complex, this specialization reformulates its analysis, reconstructs and reinterprets our problems, to rethink a systematic and restructured world through complex thinking and transdisciplinary solutions. This article evaluates particularity in university research, and reconsiders interdisciplinary, trans-complex and transdisciplinary teamwork, from connective and integral Andean thinking based on the nuclear and harmonic organization between nature, man and society. From this Andean framework, we recover the «aylluy» thought (trans-complex simplicity, unity, and sustainability) as a research model for the educational process and the environment. Fo...
