ESE

About Us

At Ecosystem Services Exchange, assisting you with the wise use and management of your water resources isn’t just a mission — it’s our commitment.

What is Ecosystem Service Exchange (ESE)?

ESE is a limited liability corporation that works directly with landowners to improve their profitability and environmental performance through the adoption of conservation drainage practices and systems that enable effective use and management of water resources.   ESE employs highly qualified and experienced technical specialists to determine site feasibility and then carry out the planning, design, and installation of conservation drainage practices and systems that enable landowners to optimize their water use.  Optimized use of available water ensures crops receive the right amount of surface and subsurface water at the right times for crop productivity while also protecting and improving the environment.

 

What Conservation Practices Does ESE Provide Technical Services for?

ESE’s technical work is performed under the leadership and oversite of a licensed professional engineer and multiple certified Technical Service Providers, registered with NRCS, who use a site-specific planning approach to respond to the unique needs of each agricultural operation.  These technical specialists assist with a wide array of water management conservation practices designed and installed to NRCS conservation practice standards, including:

  • Drainage water management (automated and manual)
  • Saturated buffers (automated and manual)
  • Denitrifying bioreactors (automated and manual)
  • Structures for water control (automated and manual) and in tile line Water Gates
  • Phosphorus removal systems
  • Drainage water recycling and subsurface irrigation
  • Constructed wetlands


How Does ESE Provide its Technical Services?

ESE works directly with landowners to help them meet their water management needs efficiently and effectively using NRCS’s time-tested and proven conservation practice standards, which are the “industry standard.”   Based on its experience with thousands of ag producers since 2010,  ESE knows that robust crop production, farm profitability, and healthy environmental outcomes are compatible goals with the right practices combined to address water management, agronomic, and soil health needs.

ESE technical services may be arranged directly by an ag landowner or through a private/public partnership project.  Landowners come to ESE directly for technical services because they recognize their water management needs, value the role of conservation practices/systems, and desire ESE’s expertise in helping them to achieve both their production and conservation goals.

 

Who Does ESE Partner With?

ESE has partnered with many private and public sector entities in 19 states and Canada since 2010. 

ESE has a long-standing business relationship with Agri Drain Corporation, a leading and recognized manufacturer and supplier of innovative, specialized, and proven conservation drainage equipment used in ESE’s practice designs and installations.   ESE also works with many other businesses, including suppliers of drainage tile, providers of agronomic technical services, and land improvement/drainage contractors.  ESE works on projects coordinated by local, state, and federal public agencies that support ag production, conservation, and the environment. 

ESE also partners with nonprofit and ag producer organizations that share common goals to assist producers with their water management needs because of its multiple private and public benefits.
 
ESE can increase its capacity as needed through business relationships with other engineering firms who have qualifications to support conservation drainage practice and system work.
 

In particular, ESE enjoys close working relationships with innumerable land improvement/drainage contractors, whose expertise and skills are essential to the installation of conservation practices and systems.  Land improvement/drainage contractors have a relationship of trust with landowners because of their proven ability on-the-ground in ag settings.

Ecosystem Services Exchange is a technical leader in helping landowners to reduce nutrient loss from agricultural lands.  We deliver significant, reliable and quantifiable results so that you meet operational goals at lower cost.  This reduces downstream impacts and community costs to treat water.

Whether it’s reducing nutrient loading in waterways, improving agricultural productivity or enhancing wildlife, we have the expertise and technical tools to help you implement cost-effective solutions.

Dave has over 40 years of professional leadership experience in natural resource conservation with the Natural Resources Conservation Service (NRCS) and in the private sector. He was Chief of the NRCS from January 2009 to December 2012. As Chief, Dave led the largest private lands natural resource conservation organization in the United States and under his leadership NRCS created and implemented landscape level conservation initiatives that focused financial and technical resources on solving issues, particularly in the areas of water quality and wildlife.

Prior to serving as Chief, he was the NRCS State Conservationist in Montana. Dave also spent significant time on Capitol Hill in Washington, DC. In 2002, he was detailed to Republican Indiana Senator Richard Lugar, and in 2008 he was detailed to Democratic Iowa Senator Tom Harkin. During those times, he worked on the conservation titles of both the 2002 and 2008 Farm Bills. Prior to that, Dave was detailed to the Clinton White House where he worked on the Building Livable Communities Initiative. 

Dave is married, has two grown children, one grandson, and three rescue dogs. Dave refuses to watch TV, believes that dogs are the most wonderful species on Earth, and still marvels that he somehow managed to graduate from the University of Missouri.

Alex Echols

Strategic Advisor

Alex started his environmental career on Capitol Hill, working for the Senate for 12 years, writing key conservation programs like the Conservation Title of the Farm Bill and an extensive rewrite of bilateral and multilateral foreign aid programs.  Alex subsequently worked for a trade association using market incentives to encourage use of recyclables. He spent six years at the National Fish and Wildlife Foundation as deputy and then acting executive director.  In 2001, he set up a consulting firm to help industry, landowners, the conservation community and government deliver more conservation for dollars invested.  Alex is skilled at developing and implementing strategic action for philanthropic and corporate communities – helping develop conservation programs that fit their core values and deliver improved conservation return on investment.

Charlie Schafer

Chief Executive Officer and Founder

Charlie Schafer, Chief Executive Officer and founder of ESE, began his career in the agricultural drainage industry in 1976.  Charlie and two brothers formed Agri Drain Corp and started installing drainage tile for Iowa farmers and soon began designing and manufacturing products for their own projects and other local contractors.  In 1984, construction activities were discontinued in order to focus solely on product development, manufacturing and distribution.
 
Charlie has held various offices as a Contractor and Associate Member of the Iowa Land Improvement Contractors Association, as well as an Associate Member of the National Association of Land Improvement Contractors Association.
 
He has served on the boards of the National Association of Conservation Districts, Conservation Technology Information Center,  Agribusiness Association of Iowa’s Environmental Committee and the Iowa Agricultural Water Alliance Business Advisory Council.  Charlie currently serves as Past President and Board Member of the Agricultural Drainage Management Coalition.
