Losing Aguacate: What If Water Costs Kill Avocado Farming in San Diego County?
San Diego County is categorized as urban, yet it was one of only three counties in the United States with over 5,000 farm operations in 2017. While continuing to expand its urban area, the county lost farmland at the rate of 3.8% every year between 2002 and 2017. By several measures, avocado production is the county's most important crop, and avocado groves account for about 30% of all crops planted there. Avocado acreage is also declining rapidly in the county, at about 3% each year. To understand
Environmental evaluation of high-value agricultural produce with diverse water sources: case study from Southern California
Meeting agricultural demand in the face of a changing climate will be one of the major challenges of the 21st century. California is the single largest agricultural producer in the United States but is prone to extreme hydrologic events, including multi-year droughts. Ventura County is one of California's most productive growing regions but faces water shortages and deteriorating water quality. The future of California's agriculture is dependent on our ability to identify and implement alternative
Global virtual water trade of avocado
This paper investigates the relationship between international trade of avocado and the related virtual water trade over the period 2000–2016. Using a Physical Trade Analysis, we show that commercial and virtual water trade grew rapidly moving almost hand-in-hand in the years taken into account: in parallel with a remarkable increase of international trade of avocado from 0.4 Mt in 2000 to 1.9 Mt in 2016, the global virtual water trade of avocado increased from 408 Mm³ to 2238 Mm³ over the same
Potential expansion of Hass avocado cultivation under climate change scenarios threatens Mexican mountain ecosystems
Analysis of potential areas for crop establishment is necessary for sustainable agricultural planning, conservation of natural ecosystems, and achievement of food security’s current global objective. This study aims to model the current potential distribution of the optimal areas for Hass avocado crop in Mexico, along with the likely impact of climate change on the crops and the surrounding mountain ecosystems in the state of Michoacán, the principal producer. The maximum entropy approach was
Resource use and GHG emissions of eight tropical fruitspecies cultivated in Colombia
The cultivation of high-value fruit species is a profitable agricultural activity in many tropical countries; however, intensive fruit cultivation may depend on high amounts of external inputs. The objective of our study was to quantify and compare the resource use during the cultivation of eight tropical fruit species (Rubus glaucus, Solanum quitoense, Passiflora edulis, Cyphomandra betacea, Physalis peruviana, Ananas comosus, Persea americana and Mangifera indica) commonly cultivated in Colombia.
