“…En ese contexto consideramos indispensable intensificar acciones de promoción y difusión de la educación ambiental para lograr el empoderamiento social sobre el uso de la naturaleza y conservación de las funciones ecológicas de las cuencas (Iwan et al, 2017). La investigación también guarda cierta similitud con el estudio realizado por Zavaleta (2020), quien estableció que la edad influye negativamente sobre la disposición a pagar de los usuarios, conllevando a variaciones en su disposición de pago; contrastando con los reportados por Quispe et al, (2021) en la que la variable edad, influye positivamente sobre la valoración económica del servicio ambiental en la cuenca del río Coata, toda vez que al aumentar la edad del usuario o jefe de familia, más dispuestos están a realizar el pago.…”

“…Entonces, a mayor aprovechamiento de los servicios ecosistémicos, el valor de la disposición a pagar disminuye. Así, estos valores expresan el grado de insensibilidad ambiental (Quispe et al, 2021). En consecuencia, son varios los factores determinantes de la disposición a pagar por servicios ecosistémicos, siendo imprescindible identificar y precisar inclusive el nivel de efecto de dicho factor sobre dicha disponibilidad (Barrial et al, 2021).…”

“…En este contexto, la valoración económica de los ecosistemas alto andinos y sobre todo el recurso hídrico en las cuencas aún es escasa, las cuales son valoradas con métodos tradicionales, que en general no contienen todos los aspectos intangibles de los recursos naturales (Quispe et al, 2021). A nivel social, los resultados registrados crean una percepción adecuada sobre la importancia del ecosistema funciones y sus contribuciones a las personas.…”

“…Quispe et al (2021) quienes estimaron una disposición a pagar de 4.88 soles, por tanto, el valor económico mensual fue de 45 935.44 soles y anualmente asciende a 551 225.28 soles; también difiere con los datosde Ramírez et al (2023), quienes estimaron la disponibilidad de pago general para las comunidades analizadas de 94.27 dólares/persona, cuyo valor económico ambiental mensual fue 5 939.10 dólares y anualmente 71 268.12 dólares.

The economic environmental valuation is a tool that assigns monetary value to ecosystem services, regardless of whether they have market prices or not. The aim of this research was to evaluate the influence of socioeconomic and environmental factors on the economic environmental valuation of water resources from the Chirimayo River basin in the districts of Chadín and Paccha (Cajamarca - Peru), and to estimate the average monthly willingness to pay by users. The contingent valuation method and Logit econometric model were used, with questionnaires and interviews administered to 285 users out of a population of 1104. Results show that the majority of users are between 46 and 60 years old, male, married, with 4 family members, primary education, farmers, with incomes between 200 and 500 soles; they use the water resource for human consumption, which is of good quality, available 24 hours a day, although the volume has decreased, and they are willing to pay for it. It is concluded that economic valuation is positively influenced by gender, level of education, and hours of service; thus, an increase in one unit of these factors leads to a greater willingness to pay. However, age and marital status have a negative influence, as an increase in age decreases the willingness to pay, and singles show less willingness. On average, 75.8% of the population is willing to pay 1.60 soles per month.

Environmental wealth is the main basis of the social, cultural and economic development of a country, but if there is an absence of the valuation of these natural resources, it can lead to a disproportionate usufruct that causes the deterioration of the ecosystem and even collateral effects of human health. This research aimed to know the total economic value of the ecosystem of the high Andean water basin tributary of the Chumbao River, located between 2000 to 4800 meters above sea level belonging to the province of Andahuaylas, Apurimac region in Perú. The valuation procedure consisted of using the analytical method of multicriteria valuation applying the concept of Total Economic Value, which involved direct and indirect uses related to environmental assets, in which a collective panel of people from different training disciplines (experts) participated, which were made up of researchers, engineers, public officials, farmers and ecologists who had extensive knowledge about the environmental asset. of the geographical area in reference; and once the paired comparison survey was done, the total economic value was quantified up to three amounts, so the respondents were formed into three statistically significant segments (SIG<0.05). The cluster (1): assigned a weighting that quantifies to an economic value of USS 4,359,179,489.46; followed by cluster (2): an intermediate value of USS 4,029,902,444.41 and cluster (3): assigned a lower value to USS 774,163,167.16. Thus, it follows that, on average, 51.78% equals value in use and 48.21% equals value in non-use, respectively. This value expressed as an interval reflects the environmental ethical positions of the groups and makes available as an indicator to government authorities and society in order to exercise actions of environmental sustainability high andean.

Purpose. The study aimed to estimate the economic value of the ecosystem services provided by the Balatin River Sub-Watershed (BRSW) as a basis for policy recommendations focused on its conservation. Methodology / approach. The economic values were estimated through the Total Economic Value approach. To estimate the use values of the provision of water supply for households and irrigation use, the market price method and productivity method were used, respectively. Meta-analysis benefit transfer was used to estimate the non-use values. Results. An estimated 1,327,560 m3 of water is supplied to households every year with total revenue of PHP 20,626,441.20 per year. PHP 4,026,773.80 is generated annually to provide irrigation water. In addition, regulating services of the BRSW generate an amount of PHP 12,191,487.85 in 2021 price levels as a benefit for the residents. This generates an estimated total economic value of PHP 36,844,702.85 with benefits spread across the users in the community. The water for drinking benefits accrue to the residents whose water is supplied by the BRSW through the Wao Water District, the benefits of irrigation water are mostly received by farmers, and the benefits of regulating services accrue entirely to the residents within the BRSW and the surrounding communities. Originality / scientific novelty. This study was able to obtain a relatively higher estimated value by using multiple valuation methods in contrast to the conventional method of using a single approach. Additionally, the study contributes to addressing the limitation in existing literature particularly in the BRSW and the remaining sub-watersheds of Lanao del Sur which also suffer from degradation. Practical value / implications. The results of this study show that the BRSW is currently an indispensable resource for the municipality. The study is a first in the municipality and can therefore be used as an input in the appraisal of the watershed’s economic value. The estimated economic value generated by the watershed illustrates a portion of what has been neglected over the past decades as the deterioration of BRSW continues.
