A major issue in the upcoming farm bill debate is likely to be funding for conservation programs. Current authorization for mandatory funding for most of these programs, under the Farm Security and Rural Investment Act of 2002 ( P.L. 107 - 171 ), expires at the end of FY2007. Mandatory funding means that the amount authorized by Congress is available unless limited to smaller amounts in the appropriations process; if appropriators do not act, the amount that was authorized is provided to the program. These mandatory funds are provided by the U.S. Department of Agriculture's Commodity Credit Corporation, a financing institution for many agriculture programs, including commodity programs and export subsidies. While most conservation programs currently are authorized using mandatory funding, discretionary funding is used for six conservation programs. For discretionary programs, appropriators decide how much funding to provide each year in the annual agriculture appropriations bill, subject to any maximum limit set in law. Conservation program advocates prefer mandatory funding over discretionary funding. They believe that it is generally easier to protect authorized mandatory funding levels from reductions during the appropriations process than to secure appropriations each year. However, since FY2002, Congress has limited funding for some of the mandatory programs each year below authorized levels in annual appropriations acts. Advocates for these programs decry these limitations as significant changes from the intent of the farm bill, which compromise the programs' ability to provide the anticipated magnitude of benefits to producers and the environment. Others, including those interested in reducing agricultural expenditures or in spending the funds for other agricultural purposes, counter that, even with these reductions, overall funding has grown substantially. Congress provided mandatory funding for selected conservation programs for the first time in the 1996 farm bill ( P.L. 104 - 127 ). Prior to 1996, all conservation programs had been funded as discretionary programs. Conservation program advocates viewed mandatory funding as a much more desirable approach, and Congress agreed, enacting provisions that moved some conservation programs from discretionary to mandatory funding. Some advocates viewed this change in funding as a major achievement in the 1996 farm bill. Amounts authorized for these programs at the time may seem modest when compared with today's levels. Programs funded with mandatory funding, and their authorized levels under the 1996 law, included the following: Conservation Reserve Program (a maximum of 36.4 million acres at any time through FY2002, with no dollar amount specified); Wetland Reserve Program (a maximum of 975,000 acres at any time through FY2002, with no dollar amount specified); Environmental Quality Incentives Program ($130 million in FY1996, and $200 million annually thereafter through FY2002); Wildlife Habitat Incentives Program (a total of $50 million between FY1996 and FY2002); Farmland Protection Program (a total of $35 million with no time span specified); and Conservation Farm Option ($7.5 million in FY1997, increasing each year to a high of $62.5 million in FY2002). The 2002 farm bill greatly expanded mandatory funding for conservation, authorizing the annual funding levels shown in Table 1 . Mandatory funding was provided both for expiring programs that were reauthorized and for new programs created in the legislation. The increase in authorized funding levels was widely endorsed for many reasons. Conservation supporters had long been seeking higher funding levels, and this was another significant step in that effort. An argument that proved particularly persuasive in this farm bill debate was documentation of large backlogs of interested and eligible producers who were unable to enroll because of a lack of funds. Demand to participate in some of the programs exceeded the available program dollars several times over, and some Members reasoned that higher funding was warranted to satisfy this demand. Funding for FY2002 is not included in Table 1 , as the FY2002 appropriations legislation was enacted on November 28, 2001, six months before the 2002 farm bill. Program funding decisions had to be based on prior legislation. Indeed, by the time this farm bill was enacted, the FY2003 appropriations process was well along. However, the 2002 farm bill did authorize money in FY2002 for several mandatory programs. In each year since FY2002, annual agriculture appropriations acts have capped funding for some of the mandatory conservation programs below authorized levels. The programs that are limited and the amounts of the limitations change from year to year. One program, the Wetland Reserve Program, has been capped in enrolled acres, which appropriators translate into savings based on average enrollment costs. Table 1 compares the authorized spending level for each of the programs with the amount that Congress actually provided through the appropriations process. It does not include any mandatory conservation programs enacted since the 2002 farm bill, including the Conservation Reserve Program Technical Assistance Account (enacted in P.L. 108 - 498 ), the Healthy Forest Reserve (enacted in P.L. 108 - 148 ), and the Emergency Forestry Conservation Reserve Program (enacted in P.L. 109 - 148 ). Many of the spending reductions originate in the Administration's budget request. Since the farm bill states that the Secretary "shall" spend the authorized amounts for each program each year, Congress must act to limit spending to a lesser amount. The mix of programs and amounts of reduction in the Administration request have varied from year to year. Congress has concurred with the Administration request some years for some programs. Starting in FY2003, the requested reductions in mandatory funding below the authorized levels (shown in the table), are as follows: In FY2003, the request was submitted before the farm bill was enacted, and did not include any requests to reduce funding levels. In FY2004, the request was to limit the Wetlands Reserve Program (WRP) to 200,000 acres ($250 million), limit the Environmental Quality Incentives Program (EQIP) to $850 million, limit the Ground and Surface Water Program (GSWP) to $51 million, limit the Wildlife Habitat Incentive Program (WHIP) to $42 million, limit the Farmland Protection Program (FPP) to $112 million, limit the Conservation Security Program (CSP) to $19 million, and eliminate funding for the Watershed Rehabilitation and Agricultural Management Assistance (AMA) Programs. In FY2005, the request was to limit the WRP to 200,000 acres ($295 million), EQIP to $985 million, WHIP to $59 million, FPP to $120 million, and CSP to $209 million, and eliminate funding for the Watershed Rehabilitation and AMA Programs. In FY2006, the request was to limit the WRP to 200,000 acres ($321 million), EQIP to $1.0 billion, WHIP to $60 million, FPP to $84 million, Biomass Research and Development to $12 million, and CSP to $274 million, and eliminate funding for the Watershed Rehabilitation and AMA Programs. In FY2007, the request is to limit EQIP to $1.0 billion, GSWP to $51 million, WHIP to $55 million, FPP to $50 million, Biomass Research and Development to $12 million, and CSP to $342 million, and eliminate funding for the Watershed Rehabilitation and AMA Programs. While Congress has reduced funding for some mandatory conservation programs, either in support of an Administration request or on its own, the reductions did not exceed 10% of the total until FY2005. However, the gap between authorized levels and actual amounts continues to grow. As a percentage, this gap has grown from 2.4% of the total authorized amount in FY2003 to 12.7% in FY2006. Even with these changes, however, actual total funding has risen almost $720 million over the same four-year time period, which is an increase of almost 25% from the FY2003 authorization. Reductions have not been uniform among programs. The largest mandatory program, the CRP, has not been limited in any way by appropriators since the 2002 farm bill was enacted. The second-largest program, EQIP, has absorbed the largest reductions from authorized levels, totaling $396 million between FY2003 and FY2006. Funding for a third program, the CSP, has been amended four times since 2002. As initially enacted, it was the first true conservation entitlement program; that is, any individual who met the eligibility requirements would be accepted into the program. Congress has capped CSP and then repeatedly reduced the cap to fund other activities, usually disaster assistance. More generally, the table shows that reductions have varied from year to year and program to program since 2002. At one extreme, the Watershed Rehabilitation Program has received no mandatory funding in any year (it is one of the five conservation programs authorized to receive discretionary appropriations as well, and those have been provided), and at the other extreme, the CRP has not been limited in any way. Some of the programs have unusual characteristics that affect how they are treated for budget purposes, as noted in the table footnotes. For example, the Grasslands Reserve and Klamath River Basin Programs each have a total authorized level that is not subdivided by fiscal year in the authorizing legislation. For those programs, the amount that was spent each year (not the remaining lifetime authorization) is included for purposes of calculating the percentage by which funding is reduced. As a result of the many variations in how these programs are authorized (some in acres and others in dollars, and some as a total amount and others by year), there are several alternative ways to calculate the annual and total reduction from the authorized level. However, all of these calculations lead to the same general set of observations. First, overall funding for the suite of mandatory agriculture conservation programs has been reduced each year. Second, the magnitude by which this suite of programs is being reduced has been growing each year. Third, these reductions may still be significant to current or potential beneficiaries of those program. Fourth, even with the reductions, overall funding for the group of mandatory programs has continued to rise.
