This manual is part of a two-part educational and outreach program to educate landowners and technical advisors about the advantages, disadvantages, costs, environmental regulations and other considerations in developing and implementing an Integrated On-Farm Drainage Management program for salinity control.
The first part of the educational program focused on the production and distribution of a guidance manual designed for landowners. It was released in 2004.
This manual is the second component of the program, and is designed to provide technical consultants and support personnel with the tools they need to assist farmers with developing and implementing an effective IFDM program.
An IFDM system can serve as a viable alternative for landowners who may not choose to participate in a voluntary land retirement program for drainage-impacted lands. Once irrigation systems have been optimized to maximize water use efficiency and to minimize the production of subsurface drainage water, an IFDM system can be designed to enable the landowner to process the resulting drainage water on-farm. Interest in IFDM is increasing.
The merits of IFDM have been recognized by the U.S. Environmental Protection Agency and the State Water Resources Control Board through the award of a Clean Water Act Section 319(h) Grant to educate farmers and to train professionals about IFDM implementation. Both manuals were funded by the grant, targeting the needs of the landowners, water/drainage district managers, engineers and technical professionals.

The Delta Working Landscapes Program (Program) is a group of projects which demonstrate how farmers can integrate habitat restoration into farming practices. The objectives of the Program are to improve the environmental quality of existing landscapes in the Delta; coordinate programs with local farmers; understand the social, economic, environmental and governmental policy hurdles and/or incentives to perform conservation practices; and communicate to farmers the advantages of implementing wildlife friendly agricultural practices.
The Delta Protection Commission was awarded a three year grant to construct the program through the California Bay-Delta Program in 2005. Program partners included California Department of Fish and Wildlife Ecosystem Restoration Program, Hart Restoration (Hart) and Ducks Unlimited (DU). Hart established vegetative buffers along irrigation ditch banks and hedgerow grass plantings. These plantings were designed to provide habitat for wildlife, improve water quality by reducing runoff of pesticides and sediment, enhance levee stability, and retard levee erosion. DU coordinated restoration enhancement projects which included creating seasonal and permanent wetlands on marginal farmlands. These projects provide waterfowl brooding habitat, a food source, and additional habitat sites which promote healthier waterfowl flocks.
These projects total 312 acres of seasonal and permanent wetlands and 6.5 miles enhanced levees and waterways. Project areas established native plant life, have been repopulated by wildlife, and filter agricultural drainage which improves water quality and enhances levee stability. Multiple species of waterfowl are using the restoration habitat for brooding and feeding as well as staying later into the season. No easements, MOUs, fee purchases, or eminent domain were used.
Challenges to Working Landscapes projects include prior long term use of pesticides and herbicides which have created a hostile environment for native plants and wildlife. Additionally, some cultural practices are not conducive to habitat creation such as practices which rely on herbicides instead of tillage. Furthermore, economic costs are affiliated with physical land alterations, and in some cases permit requirements are cumbersome.
Despite these challenges, successful public/private partnerships are possible. Working Landscapes projects can be expanded through better communication between policy and regulatory agencies and publicizing successful projects.

A new report released by the Pacific Institute and the California Green Scissors project makes the case for changing the way pesticides are regulated in California. According to the report, if California significantly increased its funding for sustainable agriculture — instead of just spending money to regulate pesticide usage — we could aid California farmers, improve the public health and save millions of dollars in associated costs.

The purpose of this report is to research the scientific literature and provide the state of knowledge on subjects that impact crop productivity with saline irrigation water and analyze the existing information from the South Delta and quantify how the various factors influencing the use of saline water applies to conditions in the South Delta.
There are five objectives for this study:
One of the objectives of this study is the review of existing literature relating to the effect of salinity on a variety of irrigated crops under South Delta conditions, preparation of a comprehensive list of references, and a synopsis of findings from key references.
A second objective is the review of the relative strengths and limitations of steady-state and transient models that have been used to determine the suitability of saline water for crop production. As part of this second objective, the strengths, limitations, and assumptions of each model when applied to field conditions are to be presented.
The third objective involves the use of soil information to determine and describe the approximate area and nature of saline and drainage-impaired soils; an estimate of the effectiveness of local rainfall in reducing the irrigation requirement; and compiling and evaluating historical crop types, acreages, and evapotranspiration information.
The fourth objective is to provide conclusions and recommendations to the State Water Resources Control Board based upon the literature, modeling, and data evaluation. Among the conclusions and recommendations to be reported the following are considered paramount. (1) Identify significant gaps or uncertainties in the literature and recommend future studies to fill the gaps. (2) Using a steady-state model and appropriate data for the South Delta, estimate the leaching fraction required for salinity control for crops regularly grown on the drainage- and salinity-impaired soils of the South Delta. (3) Using the approach as in (2), recommend a salinity guideline that could provide full protection of the most salt sensitive crop currently grown or suitable to be grown on the drainage- and salinity- impaired soils.
The final objective is to present the findings and recommendations in Sacramento to interested stakeholders and representatives of California state agencies.
