One of the primary concerns of countries with high levels of biodiversity is the conservation of species and natural environments. This prioritization is based in part on a recognition of the importance of ecosystem services, understood as the various benefits that humans derive from ecosystems, which may be developed into goods and services that are transacted in markets. The Nagoya Protocol is an international agreement whose purpose is to provide a framework under which countries can support biodiversity conservation by regulating access to native genetic materials. Such materials may be of interest to companies, organizations, and institutions for commercial, non-commercial, or both purposes. Furthermore, genetic resources constitute important inputs in numerous industries, including those in the pharmaceutical, biotechnology, botany and horticultural, agricultural, personal hygiene and cosmetics, and food and beverage sectors. The present study explores whether there is a relationship between biodiversity, the implementation of systems to protect natural areas and the quality of institutions, and the utilization of the Nagoya Protocol framework in individual countries. A Probit model was estimated to test these relationships, and a Canonical Correspondence Analysis (CCA) was conducted to identify whether the aforementioned factors explain the execution of access and benefit sharing (ABS) agreements, as measured through the lodging of Internationally Recognized Certificates of Compliance (IRCC) in the Access and Benefit-Sharing Clearing-House (ABSCH) of the Convention on Biological Diversity. The findings indicated that biodiversity conservation policies, specifically the designation of protected natural areas, are important factors that might motivate actors in Nagoya Protocol member countries to utilize the protocol system. The CCA also revealed that the quality of institution factors such as the protection of property rights, the efficiency of legal frameworks for dispute resolution, investor protection, and a low government regulation burden. also help to explain the utilization of ABS agreements.

Climate change will increase the likelihood of adverse events such as droughts, forest fires, and intensification of tropical cyclones, which are known to cause flooding (IPCC, 2014). The effects of these events are a cause of concern for both authorities and citizens, so they prioritize actions that reduce adverse impacts, especially in cities with higher risk. Therefore, the objective of this work was to measure the degree of socio-environmental vulnerability of households to identify the risk areas in the city of La Paz, Baja California Sur, one of the regions with a high degree of incidence of hurricanes in the northwest of Mexico. For this, surveys were carried out with heads of households in 251 homes, and information was aggregated to calculate the vulnerability index through principal components analysis (PCA), which were stratified by the Dalenius–Hodges method, the degree of vulnerability was classified into three categories by the Opiyo method, considering three strata of the Likert scale, 1 = highly vulnerable, 2 = moderately vulnerable, 3 = less vulnerable. The results showed that households that are in the highly vulnerable category are 33% within a range of the index −3.77243 to −0.939141. Moderately vulnerable households constitute 36% with values from −0.929141 to 0.956385. While the least vulnerable represent 31% of households with an index range of 0.966385 to 5.6952. The results have revealed the levels of high and moderate socio-environmental vulnerability by tropical cyclones of 69% homes in La Paz. The above allowed to generate risk maps that will be taken into account in planning and civil protection over adverse events.

The use of plants associated with traditional knowledge by pharmaceutical, cosmetic, agro-food, and biotechnology industries represents a potential source of benefits for indigenous groups and local communities within the access and benefit-sharing mechanisms established in the Nagoya Protocol. We used a consumer-choice experiment to evaluate consumer preferences concerning a cosmetic product with attributes related to the traditional knowledge of local plants (efficacy, price, and information). The results indicate that consumers experience higher wellness levels by consuming a cosmetic product with an information label associated with a plant of traditional use. A rise in consumer income increases the likelihood of consuming products with traditional-knowledge attributes. Higher prices are associated with a lower probability of purchase. The random coefficient reveals mixed preferences related to product efficacy level. This work shows the potential demand, by high-income consumers, of cosmetic products labeled with formulation information based on traditional knowledge associated with local plants growing in Protected Natural Areas of northwest Mexico.

The objective of this work was to estimate the local effects and spatial spillover effects of the number of vehicles, use of urban public transport, and population density on nitrogen oxide emissions for 405 metropolitan municipalities in Mexico in 2016. To this end, a Spatial Durbin Model was estimated. We found positive direct effects of the number of vehicles and population density and negative direct effects of the use of urban public transport. The number of vehicles in circulation had negative spillover effects on the nitrogen oxide emissions of neighboring municipalities. These results indicate that the design of public policy programs aimed at reducing air pollution in Mexico should be based on coordination across metropolitan municipalities.

Lack of access to piped water, as well as inadequate quantity and quality of water, are risk factors for acute gastrointestinal infections. In 2022, 4.9% of households in Mexico did not have piped water; 19.3% lacked, at some point, sufficient water for hygiene; and 18.9% perceived that the water was unfit for human consumption. During the same year, at least 1,441,226 people suffered from a gastrointestinal infection. Households without access to piped water and with insufficient water for hygiene were 27% more likely to suffer from a gastrointestinal infection than households with piped water and a sufficient supply for hygiene (odds ratio: 1.27; CI 95%: 1.26–1.28). The latent class analysis shows that 22% of households belong to the high-risk class of suffering gastrointestinal infections associated with a lack of piped water, insufficient quantity, and poor quality of water. These results provide elements for the design of public health programs through the supply of water for consumption and sanitation services.

Fishing sector fuel subsidies are designed to increase profitability by reducing costs. However, despite the number of liters of fuel subsidized in 2018 in Mexico, there is no information available on the effectiveness of the subsidies in reducing cost inefficiencies. The purpose of this study was to estimate the cost efficiency of shrimp fishing companies in Mexico, as well as measure the impact of fuel subsidies on the cost inefficiency of the sector from 2003 to 2018. The True Fixed Effects model was used to represent a Cobb–Douglas stochastic production frontier, which included a shrimp fishing inefficiencies model. The results indicate that shrimp fishing companies could reduce their costs by 25% without reducing their catch levels. Fishing companies in the Gulf of Mexico were more efficient than those operating in the Gulf of California and the South Pacific. Fuel subsidies reduce cost inefficiencies, with a greater effect when the subsidy reaches a level of 20% of the total liters of subsidized fuel.
