Farming is never without its challenges, especially in San Diego County. Compared to other farming areas nationwide, San Diego farmers face costly imported water ($600/acre ft.), biologically and nutrient depleted soils, expensive land, and difficult terrain. These pressures force San Diego farmers to be selective in the crops they plant or animals they raise.
Low rain fall coupled with record temperatures can spell disaster for California agriculture unless systemic changes take place.
On the upside, our Mediterranean climate affords farmers the ability to grow exotic and sub-tropical species that can command a high price (until the market is saturated). However, that same Mediterranean climate also means a prolonged dry season with 80% of the year's water usually arriving between December and March. Our coasts receive the least amount of rainfall, on average, with 9.9" compared to the inland mountains' 40"; both paltry numbers for one of the United State's largest agricultural...
Living in arid regions of the world can be challenging for most gardeners. Depending on your region, months may go by without a drop of rain, yet many of your plants will still need water to thrive. Here in San Diego, we may go 6 months between rains and typically, like all Mediterranean regions of the world, the dry season is also when it is the hottest and most plants really want some extra water. There are many strategies for landscaping and gardening in the drier parts of the world and many of them address techniques to conserve water and minimize evaporation. Greywater is one strategy that can be quite effective in providing year round irrigation in arid regions.
Greywater is any freshwater used in the daily household activity that originates from the shower, bath, sinks, and washing machine.* Basically, any water used in the house that does not come from the toilet (used toilet water is called “black water”). Think of it as lightly used water...
