Much like the Salton Sea, many inland bodies of water suffer from rising salinity, which can harm biota and prevent beneficial water use. This salinization occurs when soil, which contains salts and minerals, is mobilized from clearing natural vegetation or when fresh water is diverted for irrigation.  As irrigation water and drinking water sources become increasingly salty, different solutions become necessary to recover freshwater. Saudi Arabia is the world’s leader in desalination, which is the industrial process of removing salt from water, with 50% of the nation’s drinking water recovered from seawater.  At the Salton Sea, desalination is being explored as a part of habitat restoration efforts. Continue reading “Desalting the Sea: Part 1”
Here at Salton Sea Sense we have tried to show that despite all the problems facing the Sea, there is hope. Hope that the Sea can thrive for generations to come, providing habitat for wildlife, continued environmental stability, and potentially increased economic opportunities. But, between the growing California population, the demands of agriculture, the historic drought and the needs of the Sea our water resources are being stretched to the breaking point. In order to meet these demands Californian’s have worked hard to find places to cut water use. This idea has spurred many ideas and catchy slogans, such as don’t wash your car and “go dirty for the drought” or let your lawn go “California Golden.” But by far the largest use of water in California is not our lawns or even our almonds; it is our meat and dairy production. Therefore, the best solution to our water scarcity problem is not found in our backyards, but at the end of our forks.
Meat and dairy production in California consumes 47% of our total water use, where as household water use only accounts for 4% and yes that includes those lawns[i]. The main perpetrator of this water use is one of the feed crops used for cattle: alfalfa, which also happens to be the primary crop grown in the Imperial Valley. Alfalfa uses over 5000 acre feet/year of water, nearly twice as much as the next crop, rice (table 2).* The last United Nations Environmental Program (UNEP) report from the International Panel for Sustainable Resource Management emphasized Continue reading “Skip the Steak & Save the Sea”
Several months ago, the Torres Martinez tribe announced that they will be growing medical marijuana on tribal lands in the near future. The income from this growing operation could provide the Torres Martinez tribe, and the surrounding area, with a much needed economic boost. However, large-scale growing of the water-intensive marijuana plant may pose an environmental risk in an area already gripped by drought.
Last week, Imperial County and the Imperial Irrigation District (IID) released a draft of a proposal developed to be presented to the State of California. This proposal, named the Salton Sea Restoration and Renewable Energy Initiative (SSRREI) is different from previous remediation proposals submitted on behalf of the Salton Sea by various groups. This proposal in particular does not merely ask for a large sum of money, but delineates just how the state can fund the project and recover its investment. Continue reading “Response to SSRREI”
The primary issue at the Salton Sea is the declining water level due to reduced water inflows and excessive evaporative losses. The main consequence of this is an increase in salinity, which in turn creates a sequence of other complications. The increasing nutrient concentration causes a dense growth of phytoplankton and plant life which deprives the Sea of oxygen and causes massive fish die offs. As the fish die, many bird species find it difficult to survive. In addition, as the Sea dries it exposes playa, which releases dust containing dangerous chemical compounds buried at the bottom of the Sea from decades of agricultural runoff.
It is evident that the consequences of allowing the Salton Sea to dry are quite disastrous and that they affect the aesthetic and ecological integrity of the Sea. It might seem that the key to preventing the Salton Sea from drying up lies in simply increasing the amount of water that goes into the Sea, but where to get the water from? That is a question that is far from simple and one that might not have a reasonable answer.
