Long-Term Trajectory Analysis of Avocado Orchards in the Avocado Belt, Mexico
Avocado orchards are among the most profitable and fastest-growing commodity crops in Mexico, especially in the area known as the “Avocado Belt”. Several efforts have been made to monitor their expansion; however, there is currently no method that can be easily updated to track this expansion. The main objective of this study was to monitor the expansion of avocado orchards from 1993 to 2024, using the Continuous Change Detection and Classification (CCDC) algorithm and Landsat 5, 7, 8, and 9
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
Economic analysis of avocado production systems: Market failures and policy distortions
This study aimed to evaluate competitiveness and profitability at private and social prices, and assess the impact of policies and market failures on avocado production in the State of Mexico. Data were collected from 11 high-density plantations with mature trees between January and July 2021. Three groups were formed, and the Policy Analysis Matrix revealed that all Avocado Production Units (APUs) were profitable at private prices. APU 3 remained competitive when land costs were included, but none
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
Avocado production in different biomes throughout Peru: do differing cultivation practices translate into differences in environmental impacts?
PURPOSE: Avocado production in Peru takes place in different biomes and under different agricultural systems (e.g., conventional, organic, or agroforestry). Therefore, it is important to understand differences in the environmental profile of avocado production within the diversity of these cultivation systems. Hence, the main objective of the study was to conduct a cradle-to-gate attributional Life Cycle Assessment of avocado production in Peru by small and medium-sized producers, under multiple
