An Invitation

The United States of America, in cooperation with its North American partners, is pleased to invite land and water conservation researchers, educators, policymakers, practitioners, and advocates throughout the world to participate in the 10th International Soil Conservation Organization (ISCO) Conference, May 23-28, 1999, at Purdue University in West Lafayette, Indiana, USA. ISCO is an independent organization that promotes international exchange on the science, technology, policy, and application of land and water conservation.

The conference theme, Sustaining the Global Farm, Local Action for Land Stewardship, acknowledges that we all live together on this planet, that each of us has a critical stake in maintaining the quality of our global environment, that soil conservation has fundamental significance as the basis for sustaining life, and that stewardship of natural resources ultimately depends upon the individual actions of each and every person.

The 10th ISCO Conference provides a forum for land and water conservationists from around the world to come together to exchange information and ideas and to express their views on the "state of the world" and what can and must be done to achieve sustainability in land use. The meeting also provides an opportunity to extend the personal and professional networks that are critical for finding solutions to any global problem. And the midweek conference tour, along with the pre- and post-conference tours and workshops, will introduce participants to the conservation challenges associated with agricultural systems in the United States.

Please join us during springtime in the USA for what is certain to be a stimulating educational experience.

Land and water are critical natural resources that sustain human life and the lives of all other creatures on our planet. The careful husbandry of these natural resources is essential to world food security and environmental protection. When used in sustainable ways, land and water produce the food, fiber, and energy products that we all depend upon, and they will do so indefinitely. Sustainable use of land and water also is essential to maintenance of socially, economically, and ecologically viable communities.

It is imperative, therefore, that we invest adequately in research, technology development, and the effective transfer of new technologies. These are the roots of sound science on which the sustainable use of land and water resources is based. Sound science also supports sound conservation policymaking, which often is the stimulus for local action. In the end, however, it is local action-by the community or by the individual farmer or landowner-that will yield a degree of land stewardship sufficient to sustain our "global farm."

The defining characteristic of ISCO is its "inclusiveness." The scope of the 10th ISCO Conference, therefore, may encompass, but is not limited to, the following:

The science of land and water degradation, including soil erosion, and models and methodologies to assess land and water degradation, nonpoint-source water pollution, soil quality, and watershed health; applications of geographic information systems and related tools; the usefulness of prediction models and technologies for specific local and regional or watershed situations.

Local- and regional-scale surveys of soil quality or soil health from various parts of the globe, history and use of soil survey and its implications for land and water conservation, impacts of soil and water conservation on nonpoint-source water pollution, conservation of biodiversity, improving national and international information on land degradation, global climate and its implications for land and water conservation, agriculture's role in carbon sequestration.

Economic and social costs of land and water degradation, bioeconometric models to assess the economics of land management decisions, tests of why farmers do or do not adopt conservation technologies, socioeconomic constraints to achieving sustainability, linkages between conservation and both agricultural and environmental protection, techniques to compare the costs and benefits of improved land use and management, indigenous knowledge as a basis for land stewardship, valuation of environmental benefits from land conservation, global demographics and implications for land use, pollution credit trading, costs of restoration versus protection, and success of donor aid programs.

Processes, resources, and coordination of global, national, regional or watershed, and local conservation efforts; national policies to foster local partnerships and action; use of incentive and regulatory program mixes to achieve land and water conservation; building constructive bridges between agricultural and environmental interests; alternative institutional arrangements for information exchange and technology development; role of private institutions, including agribusiness, in conservation.

Examples of how individual farmers, groups of farmers, and/or communities are working successfully to protect land and water resources; partnerships, including rural and urban linkages, that have worked to conserve land and water resources; organizing public and private partnerships; use of culture-based networks to achieve sustainable land use; mobilizing for on-the-ground delivery of conservation programs; effective agroforestry practices; on-farm best management practices; salinity management technologies; environmental implications of precision farming; crop residue management for soil improvement and increased farm profitability; land application of livestock manure and other wastes, both agricultural and nonagricultural.

Conference Format

The 10th ISCO Conference will begin with registration and an evening reception on Sunday, May 23. Invited and volunteered presentations will be featured during the week's plenary and concurrent sessions. An exhibition during the conference will include poster papers, demonstrations, and educational displays. A mid-week tour

on Wednesday, May 26, during spring planting in the Corn Belt, will acquaint conference participants with natural resource management challenges on cropland and in the rural/urban fringe. Also planned is a banquet on Thursday evening, May 27.

Participants will also have the opportunity to take part and actively shape the outcome of the conference through structured discussion sessions on the state of the global land resource and strategies to sustain it.

Call for Contributions

The 10th ISCO Conference will provide an opportunity for individuals to present original ideas and information to an international audience of land and water conservationists. A program committee will review all abstracts offered and determine which contributions, in which form, will best meet the conference objectives.

C. Revised Universal Soil Loss Equation (RUSLE) Training  May 21-23, 1999

Conducted by the RUSLE Development Team from the Agricultural Research Service, Natural Resources Conservation Service, and University of Tennessee, this workshop will present the science and technology behind the Revised Universal Soil Loss Equation. RUSLE is a revision and update of the Universal Soil Loss Equation (USLE), which has been widely used around the world. RUSLE retains the equation structure of the USLE, but each factor has been either updated with recent data, or new relationships have been derived based on modern erosion theory and data. RUSLE has recently been implemented for use on cropland in the U.S. by the USDA-Natural Resources Conservation Service, and is being implemented in several other countries. Also, the USDI-Office of Surface Mining and Bureau of Land Management, the Environmental Protection Agency, and several state regulatory agencies are also now requiring use of RUSLE for erosion control planning on construction sites, mineland reclamation, and landfill covers. Several applications of the technology that demonstrate its flexibility for use in conservation planning, inventory of soil resources, mineland reclamation, construction, and international agricultural systems will be illustrated with hands-on practice. A brief overview of WEPP is included.

The workshop begins at 9 a.m. on Friday, May 21, and concludes at 5 p.m. on Sunday, May 23. Limit 20 participants. Cost: $200, includes workshop materials.

D. Water Erosion Prediction Project (WEPP) Training  May 21-23, 1999

Conducted by the staff of the National Soil Erosion Research Laboratory, this workshop will cover the science and application of the Water Erosion Prediction Project (WEPP) model. WEPP is new-generation erosion prediction technology developed by a team of scientists from several government agencies and many universities from 1985-present. WEPP is a physically-based, distributed-parameter, continuous-simulation model implemented on personal computers. It can be used to predict runoff, soil loss, deposition, and sediment yield from small watersheds or individual hillslope profiles within watersheds. This workshop will present information on the science embodied in the model, model validation and testing results, and the progress of work to link the WEPP watershed model with a Geographic Information System. Two days of hands-on use of the model for typical field applications as well as applications of specific interest to workshop participants are planned. A brief overview of RUSLE is included.

The workshop begins at 9 a.m. on Friday, May 21, and concludes at 5 p.m. on Sunday, May 23. Limit 20 participants. Cost: $200, includes workshop materials.

Periodic rainshowers are likely. Reasonably light cotton clothing will be appropriate, with a jacket for evenings.

Dress for conference sessions during the day will be informal. Business casual attire (slacks and coat, without necktie) is appropriate but not essential for the conference receptions and banquet.

Currency, Banking and Credit Cards: U.S. dollars are the legal tender. Denominations of $1 or more are in the form of paper notes-$1, $5, $10, $20, $50, $100, etc. Coins are used for amounts less than $1-1 cent, 5 cents, 10 cents, 25 cents, and 50 cents.

Banking hours in the United States vary by location. Most banks are open each weekday from 8 or 9 a.m. to 4 or 5 p.m. Most are open on Saturday mornings as well, generally from 8 or 9 a.m. til noon or 1 p.m. Currency exchange booths are common in international airports, Chicago and Indianapolis, for example.

Most hotels, restaurants, and shops accept international credit cards, such as VISA, MasterCard, Diners Club, and American Express. Travelers' checks are also commonly accepted. For conference registration purposes, the credit cards that Purdue University Conferences will accept include VISA, Mastercard, and Discover.

Restaurants: The Purdue Memorial Union and Stewart Center feature a number of cafeterias and restaurants with a variety of food choices and extremely reasonable prices. A number of other restaurants, cafes, and coffee shops are within walking distance of the conference venues.
