Impact of agriculture on forests

19/09/2025 Go to Evidence

The study assesses the impact of converting Amazonian forests to agricultural land in the Peruvian Amazon, analyzing how this transition affects soil organic carbon, total nitrogen, and available potassium. The results show a significant decrease in these essential components, reaching critical levels that compromise fertility, agricultural productivity, and ecological sustainability (Solórzano et al., 2025).

Bioferments improve cocoa growth

07/09/2025 Go to Evidence

This study evaluates the effect of different bio-ferments on the morphology and quality of cacao (Theobroma cacao L.) seedlings under nursery conditions. Treatments were compared based on parameters such as height, stem diameter, number of leaves, and seedling quality. The results show significant improvements in growth when bio-ferments are applied, highlighting their potential as an agroecological input for early stages of cacao development (Chuquizuta et al., 2025).

Farmers and Climate in Peruvian Amazon

11/03/2025 Go to Evidence

In Peru’s Upper Huallaga basin, 73 structured farmer interviews were integrated with local station and ERA-5 data. A temperature rise of +0.2 °C per decade matched farmers’ perceptions. Increased crop water deficit and surplus volumes suggest more intense sub-daily convective rainfall, helping explain perceived changes in precipitation and wind (Serrano et al., 2025).

Peru's agricultural diversity post-COVID-19

14/05/2024 Go to Evidence

This study assessed crop diversity among 180 Peruvian farmers (2018–2022) using Shannon–Weiner and Margalef indices. Five crop types were identified; projections indicate growth in 15 families and decline in 9 by 2025 (Chavez et al., 2024).

Natural fertilizers in Aymara agriculture

27/07/2023 Go to Evidence

The research analyzes ancestral practices of using natural fertilizers and biocides in Aymara agriculture in Puno, Peru. Through an ethnographic approach, it documents how peasant families use organic resources (such as plants, minerals, and human urine) to fertilize soils and control pests, thus preserving agricultural sustainability and traditional wisdom.
