The Institute’s vice-president for small firm interests describes AICPA programs for small firms and their small business clients.

by James C. Metzler

Small businesses—the fastest-growing sector of the U.S. economy—rely on their CPAs for business advice, making them a core practice area for many practitioners. In recognition of this important relationship, the AICPA provides specialized resources, advocacy and other services aimed at keeping this connection solid.”

THE PCPS FIRM PRACTICE CENTER

This dynamic, new online resource provided by the Private Companies Practice Section (PCPS) offers free tools and information to help AICPA members strengthen their practices and better serve their clients. By clicking on the Resources tab on the center’s home page (www.aicpa.org/pcps), members can find sections for closely held companies, not-for-profit entities and many other practice areas. The closely held companies section, for example, contains articles on how to find fraud in private companies or improve the value of boards of directors. The tax section provides news and informative articles on topics such as changes in the tax laws. Other sections address practice management, staffing, succession planning, keeping up with standards and technology and other issues important to firms serving small businesses. The center also contains a wide variety of premium content on subjects ranging from leadership to setting goals for firm partners. To introduce these special resources to practitioners who are not PCPS members, content on the site is available free to all AICPA members until May 15, 2006.

SummarySoil erosion poses a serious problem for sustainable agriculture and the environment. Owing to long-term anthropic pressure including overuse and inappropriate development, soil erosion has become a serious issue in the Three Gorges Area (TGA), China. Recently, integrated small watershed management (ISWM) for soil conservation in the TGA was rapidly developed. This study was conducted to investigate the impact of ISWM on soil erosion and sediment delivery in the Wangjiaqiao watershed in the TGA. The WATEM/SEDEM distributed erosion and sediment transport model was used to evaluate the effectiveness of the ISWM project. The model was calibrated against long-term measured suspended sediments at the watershed outlet. Land use and conservation measures were mapped and analyzed for 1995 and 2005, paying particular attention to quantification of changes in soil erosion and sediment delivery due to ISWM. The results showed that a combination of decreased soil loss (from 18.5 t ha-1 y-1 in 1995 to 13.2 t ha-1 y-1 in 2005) and increased sediment deposition (from 7.7 to 12.4 t ha-1 y-1) has led to a strong decrease in sediment yield (from 8.4 to 3.9 t ha-1 y-1) and the sediment delivery ratio (from 0.454 to 0.295). The results of scenario analysis showed that soil conservation measures taken in fields effectively reduce on-site soil loss and sediment yield. However, off-site sediment control measures appear to be much less effective at reducing sediment yield. This diachronic comparison of soil erosion and sediment delivery revealed that ISWM is quite effective and efficient; therefore, it is the appropriate method to combat soil erosion in the TGA and similar areas.

چکیده:

فرسایش خاک یک مشکل جدی برای کشاورزی پایدار و محیط زیست است. فشار بیش از حد انسان بر روی این منابع از جمله استفاده بیش از حد و توسعه نامناسب، سبب شده است که فرسایش خاک به یک مشکل جدی در منطقه TGAچین تبدیل شود. به تازگی، مدیریت یکپارچه حوضه‏های کوچک (ISWM) برای حفاظت خاک در TGA به سرعت توسعه یافته است. این مطالعه به منظور بررسی اثرات ISWM بر فرسایش خاک و تحویل رسوب در حوضه Wangjiaqiaoدر منطقه TGA چین انجام شد.

مدل WATEM/SEDEM توزیع فرسایش و انتقال رسوب برای ارزیابی اثربخشی پروژه ISWM بکار برده شد. مدل برای رسوبات معلق اندازه گیری شده در دراز مدت در خروجی حوضه کالیبره شد. کاربری اراضی و اقدامات حفاظتی نقشه‏برداری شد و برای سال‏های 1995 و 2005 مورد تجزیه و تحلیل قرار گرفت تا تغییرات کمی و کیفی نرخ تحویل رسوب و فرسایش خاک
