California farmers are seeing new nitrogen monitoring requirements they must implement in the years ahead. The state of California continues discussion on how growers can improve nitrogen use efficiency and how California can best respond to increasing concerns about nitrogen's movement through our environment. Nitrogen continues to be a pressing topic for California agriculture.
As part of that discussion, members of the public are invited to participate in the Stakeholder Review of the California Nitrogen Assessment (CNA), a comprehensive examination of the existing knowledge on nitrogen science, policy, and practice in California. Researchers have collected and synthesized a large body of data to analyze overall patterns and trends in nitrogen imports, exports, internal flows and storage throughout the state.
The CNA was designed to respond to stakeholder needs, and many scientists affiliated with UC Agriculture and Natural Resources were involved in the writing and review of the document. The review process is an opportunity to hear from stakeholders to understand how well the assessment meets those needs and what improvements can be made to the CNA before its publication. This approach aims to move beyond academic “business as usual” to more effectively link science with action and to produce information that informs both policy and field-level practice.
The Agricultural Sustainability Institute at UC Davis, the CNA's convening institution, is hosting a chapter-by-chapter public review process to allow stakeholders an opportunity to comment on the document before its final release.
On Friday, June 12, UC SAREP hosted a webinar of Chapter 8: “Responses: Policies and Institutions.” View the webinar here. The webinar includes an introduction to the chapter by its lead author, Ken Baerenklau, associate professor of environmental economics and policy at UC Riverside, and instructions for how stakeholders can submit comments on the chapter.
Chapter 8, “Responses: Policies and Institutions,” provides an overview of available policy instruments for nonpoint source pollution control and examines outcomes from the implementation of these policies in previous cases to control nitrogen pollution in practice.
This is the fourth in a series of webinars and stakeholder review periods to discuss the California Nitrogen Assessment, which includes:
- Identification of underlying drivers (e.g., regulations, population growth) and direct drivers (e.g., fertilizer use and soil management, fuel combustion) that affect stocks and flows of nitrogen in California agriculture.
- Calculation of a mass balance to examine how nitrogen moves through California agroecosystems and the state as a whole (including agriculture, sewage, industry and transportation).
- Evaluation of the state of knowledge about nitrogen's impacts on ecosystem health and human well-being.
- A series of scenarios, or "plausible stories about the future," that provide insights about nitrogen issues that will require attention over the next 20 years.
- A suite of practices and policy options and the potential effects each would have on agriculture, the environment and human health.
Stakeholder comments for Chapter 8 will be accepted until June 26, 2015. The comment period for Chapter 7, “Responses: Technologies and Practices” is still open, with comments due by June 15, 2015. The webinars for all stakeholder presentations done to date are available on the California Nitrogen Assessment's website.
