Abstract

Purpose

This paper aims to characterize the sexual maturation of M. flexuosa plantations in Tulumayo.

Design/methodology/approach

The methodology in this paper was selection of three plots in open field and usage of different densities of planting, after the maturation of the first plants, we began the quarterly evaluation. There was total 28 evaluations in seven years of age.

Findings

As a result, it was determined that at 12 years, the plots with lower density presented a greater number of mature individuals, with a predominance of female palms that produced an average of four bunches of fruit per year, and males five inflorescences. In addition, 15% of adult female plants went dormant, whereas males accounted for 3.4%. Reproductive cycles began in September and culminated in October of the following year, which were synchronized with rainfall.

Originality/value

Planting density was a determining factor in the early maturity of M. flexuosa and sustainable plantation management.

Abstract

Purpose

The purpose of this paper is to present the first economic valuation of four environmental attributes of the Yanachaga–Chemillén National Park (PNYCH – Parque Nacional Yanachaga-Chemillén) in Peru.

Design/methodology/approach

This study included households in three cities adjacent to the PNYCH and assessed the willingness to pay (WTP) for preservation efforts of these natural services to avoid the predicted loss in forest area by 2030 (currently 143,425 hectares per year).

Findings

The results showed that the average WTP was US$0.695 (2.3197 soles) per household annually. Added to all households in Peru (9 million), this is equivalent to approximately 6.255 million dollars annually.

Practical implications

The economic valuation of these attributes is complementary to the contingent valuation and can have a significant impact, as this data influences decision-making and public policies focused on conserving forests and biodiversity.

Social implications

Upon using the choice experiment (CE) model, the attributes that have the most significant impact on inhabitants’ well-being were economic benefits. The flora and fauna coverage attributes were beneficial for the inhabitants of the place because they valued the proposed recovery and conservation program in a positive and differential way.

Originality/value

From the collection of valuable economic data, the novelty lies in using the CE method, which has not yet been applied in valuations of natural ecosystem services in Peru.
