Osmolyte Regulation as an Avocado Crop Management Strategy for Improving Productivity Under High Temperatures
Climate change worsens abiotic stresses, primarily due to high temperatures, which have a negative impact on avocado productivity, leading to reduced crop yields, affecting fruit set and abscission. To tackle these challenges, antioxidants such as glycine, choline, and proline can enhance plant tolerance to these stressors and minimize plant cell damage. This work aimed to use these antioxidants to improve avocado commercial yield and quality under challenging environmental conditions. This study
Technological Adoption Management System for Small-Scale Hass Avocado Producers (SATPA)
This research develops a proposal aimed at enhancing the competitiveness of Colombia’s Hass avocado sector through the design and validation of a Technological Management System (TMS) that modernizes and makes the production processes of smallholder farmers more sustainable. The proposed system enables producers not only to comply with international phytosanitary and environmental regulations but also to integrate efficiently into export markets, particularly the European Union, where frameworks
Impacts of Converting Native Grassland into Arable Land and an Avocado Orchard on Soil Hydraulic Properties at an Experimental Farm in South Africa
The main objective of this study was to evaluate the changes in soil water retention curve (WRC) and pore size distribution in the 0–10, 10–20, and 20–30 cm layers following grassland conversion into arable land and an avocado orchard. Undisturbed soil cores were sampled using cylindrical metal cores to determine WRCs. The RETC program was used to fit the van Genuchten equation to the measured water retention data. The maximum equivalent radius (r) of soil pores retaining water at various matric
Estimation of the forest area required for water sustainability of avocado in the south of the State of Mexico
This study analyzes the relationship between forest cover and water supply required for avocado (Persea americana) cultivation, in order to determine a balance between these two; based on the “Water Yield” model, which makes it possible to quantify water production in a specific watershed. The results obtained enable establishing the amount of forest needed to provide adequate water supply for avocado, in the context of the growing demand for this agro-food product worldwide. In this sense, it
The Hass Avocado Boom as a Catalyst for Socio-Natural Regime Transitions in the Global South: Insights from Northern Caldas, Colombia
"The global hass avocado (Persea americana ""Hass"") market has seen significant growth in recent decades, driven by increasing demand in key markets such as the United States, the European Union, and China (Denvir et al., 2021). Mexico is the world's leading producer and exporter, accounting for more than 40 percent of global production (Caro et al., 2021). However, other countries, including Peru, Chile, and Colombia, have expanded their market share through intensive production strategies and
Telecoupled social–ecological systems: the case of avocado in Chile
The popularity of avocados has increased globally in alternative diets, alongside its integral role in Latin American cuisine. In Chile, avocados are grown extensively and intensively in orchards in the dry and Mediterranean climate of Central Chile. Avocado is a water-demanding crop and the severe water crisis in Chile has called attention to the conflicts caused by its water use. As most of the pressure to produce avocado comes from international demand but results in impacts on native ecosystems
