Work on the All-American Canal is going forward so rapidly that the great 80-mile ditch and its appurtenant features will be ready to de­liver irrigation water to the Imperial Valley in southeastern California some time during the first half of 1938. The waterway is being dug across a normally desert region that once formed the wa­ter bed of the prehistoric northern ex­tension of the Gulf of California, as we know it today. Paradoxically, that far­ flung section of the Gulf was transform­ ed into a generally barren and arid region by the very river that is to be tapped to assure the continued agricul­tural productivity · of soil that can be made amazingly fruitful by irrigation.

Flood-MAR Research and Data Development Plan

The Research Advisory Committee (RAC) is pleased to make this plan available to the growing network of farmers, researchers, planners, and water and land managers who want to expand our collective knowledge about using floodwaters for managed aquifer recharge (Flood-MAR). This plan outlines the priority information needed by those making management decisions about the where, when, and how of capturing available flood water to replenish California’s depleted aquifers.

From crisis to connectivity: Renewed thinking about managing California’s water & food supply

California Roundtable on Water and Food Supply (CRWFS) | April 14th, 2014

Modern water management has largely focused on the near-term objectives of a particular user group, be it agriculture, urban, or environment. Over time, competing demands

Modern water management has largely focused on the near-term objectives of a particular user group, be it agriculture, urban, or environment. Over time, competing demands for our finite water resource has led to intractable water conflicts and a water infrastructure that is managed by a highly complex and fragmented network of local, state, and federal institutions. These institutional and water infrastructures abound with missing, broken, or dysfunctional connections between agricultural, urban, and environmental water users, creating negative impacts for all. Addressing these challenges requires a new and strategic approach that is based in understanding the whole system. Fortunately, a shift toward a whole-systems approach is already developing within a number of disciplines that inform water resource management, food supply systems, and environmental stewardship. In this report, From Crisis to Connectivity: Renewed Thinking about Managing California’s Water and Food Supply, the California Roundtable on Water and Food Supply (CRWFS) builds on this shift and identifies the concepts of connectivity and connected benefits: » Connectivity defines the relationships that link the individual parts of a system to form a whole. It recognizes that the actions of one component within a system have an impact, both on the other components of that same system, and upon other, linked systems. The connectivity approach uses this understanding to better align the interactions between human systems (i.e., engineered resource systems, cultural norms, and institutions) and ecosystems (i.e., climatic, chemical and biological systems, and natural resources). This approach proposes that human systems are a central subsystem of the larger ecosystems, rather than systems that exist apart from and only linked to ecosystems. The goal of this alignment is to more effectively design for, and simultaneously achieve, benefits for agricultural and urban users, while ensuring environmental restoration, protection, and stewardship. » The concept of connected benefits refers to achieving simultaneous benefits across all major water users. The idea of connected benefits builds on the positive historical trend from single to dual and multiple benefits that evolved as a way to respond to California’s increasing water management challenges. Based on our assessment of current needs and the patterns of disconnects, we have identified three initial high-priority areas in which we believe the connectivity approach can effect significant change in California’s food and water systems. Each high-priority area has several principles to help guide assessment of water and food issues, as well as design and implementation of solutions.

Further Trade Wars Will Harm California Agriculture

University of California, Davis (UC Davis) | September 30th, 2024

As protectionist policies gain momentum in the United States, the future of California’s agricultural trade faces pessimism. With proposals to expand tariffs on imports

As protectionist policies gain momentum in the United States, the future of California’s agricultural trade faces pessimism. With proposals to expand tariffs on imports from China and other nations, California farmers—who depend on global markets as an outlet for their almonds, wine, and other agricultural goods—are aware that there would be trade retaliation from our trading partners. If a significant new trade war develops, California could see a quarter of its agricultural exports wiped out, costing the state’s economy $6 billion annually.

Gaps and opportunities in nitrogen pollution policies around the world

Nitrogen pollution is an important environmental issue gaining traction in policy circles. However, there is little understanding of current nitrogen policies around the world: whether they account for nitrogen’s unique ability to exacerbate multiple environmental impacts or balance nitrogen’s dual role as an essential agricultural input and major pollutant. Here we assemble and analyse the first database of nitrogen policies generated by national and regional legislatures and government agencies, a collection of 2,726 policies across 186 countries derived from the ECOLEX database. The database covers all major environmental sinks (such as air, water and climate), economic sectors (including agriculture, wastewater and industry) and policy instruments (from market mechanisms to regulatory standards). We find that sink-centred policies are focused predominantly on water, mirroring the distribution of nitrogen’s global environmental and human health costs. However, policy integration across sinks is severely lacking, which heightens the risk of substituting one form of nitrogen pollution for another. Moreover, two-thirds of agricultural policies (ranging from broad sectoral programmes to nitrogen-specific measures) incentivize nitrogen use or manage its commerce, demonstrating the primacy of food production over environmental concerns.
