Many conservation programs in subordination to the 2002 Farm Act address resource make uneasys such as water quality and aquatic communities in streams. Analyzing sum of two units such programs, simulated changes in agricultural practices decreased field-edge sediment losse from 25-31% in two geophysically distinct Minnesota watersheds. However, while in-stream sediment concentrations and lethal fisheries conclusions decreased significantly in one watershed, there was no discernable improvement for the fisheries in the other, despite potentially spending from one side of to the other $ 100,000 annually in conservation payments. These be the effects highlight the importance of performance-based conservation payments targeted to genuine resource touchs in watersheds and the value of integrated bioeconomic modeling of conservation programs.

Over the last 70 years, the federal restraint has worked with agricultural farmers and land owners to jam natural resources such as soil, mitigate negative environmental externalities like water pollution, maintain without deductions farm income at some acceptable horizontal and keep budgetary outlays within an fiscally responsible limit. Programs that encourage farmers to use crop residue management (conservation tillage) practices, or programs as it is as the Conservation Reserve Program (CRP) that advance the retirement of highly erodible lands, have been somewhat fortunate at reducing soil losses (Conservation Tillage Information Center 2003; Ribaudo, Osborn, and Konyar, 1994)

Despite of the like kind efforts, agricultural production activities remain the same of the primary reasons for water quality impairment or nonattainment of designated uses (fishable, swimable, or drinkable) for riverine classifications (60%), and to a inferior extent lakes (30%), estuaries (15%) and ocean shoreline areas (15%) in this rural parts (U.S. Environmental Protection Agency, 2000) Given this situation, common might wonder if conservation programs designed to resolve into soil loss effectively protect water quality in general, and more specifically, fisheries populations in freshwater environments.

Recently below the Conservation Title of the 2002 Farm Security and Rural Investment Act (FSRIA) (the 2002 Farm Act), a novel conservation initiative for working lands was created. The Conservation Security Program (CSP) is a performancebased program which rewards farmers with "green payments" for conservation practices or erections that address environmental or natural resource be of importance tos such as soil loss, water quality, and fisheries and wildlife habitat. The CSP was designed to "reward the best and motivate the rest" (7 CFR Part 1470 p 7720)

In this contemplation we examine how well the CSP and the CRP address water quality and freshwater fisheries disquiets in two different watersheds in Minnesota, and estimate to what extent such programs affect producer income and to what degree much they cost the guidance The timely analysis presented in this research demonstrates that if programs like CSP are to be prosperous they may need to be targeted more toward the actual resource regard of interest to the the community in a given watershed. For example, if the resource touch is fisheries and the conservation practices being supplyed by this program do not ensue in a measurable improvement in this resource, then the program is not same effective or economically efficient. Another contribution of this research is its description and demonstration of the usefulness of tools like integrated bioeconomic protoplasts for analyzing complex biophysical processe and the policies designed to influence them.

For an ex ante analysis of in what manner cost-effective conservation programs might be, or to determine by what mode successfully such programs might address the environmental affairs for which they were designed, an integrated bioeconomic standard is crucial (Wu et al, 2004) With an integrated approach, a bioeconomic prototype incorporates the field-level economic information of land use changes and the biophysical or environmental impacts of these alternative land management a whole s and aggregates them up to a larger scale, like as a watershed or river sub-basin or basin.

This approach to modeling and analyzing agricultural conservation programs is crucial because it captures the heterogeneous nature of the landscape and deliberates the level at which many economic and agronomic decisions are made-the field. by means of modeling the physical process at the field flush and aggregating up to the watershed, the spatial variability and nonlinear impacts of farming a whole s on the environment can be captured. Furthermore, the differing economic impacts of conservation programs forward various farming systems can be captured with this integrated bioeconomic analysis.

Review of Literature

The increased sediment from many agricultural practices, primarily row-crop production, adversely influences the arrangement and function of streams, and oftentimes changes fish diversity (size and age pile and species composition) and temporal variability in fish abundance (Berkman and Rabeni, 1987; Schlosser 1991; Harding et al, 1998; Schleiger, 2000) Sublethal and lethal events on fish assemblages from suspended sediment include avoidance behavior, impaired respiration, reduc feeding rates and extension reduced tolerance to disease or toxicants, increased physiological stres and mortality (Newcombe and Jensen 1996)
