Title: Richard H' Moore, OSU


1
CLIMATE CHANGE AND LOCAL WATERSHED ECOLOGY In
North Central Ohio and NE Japan
  • Richard H. Moore, OSU
  • Interim Director,
  • OSU Environmental Science Graduate Program
  • Moore.11_at_osu.edu

2
Assumptions of Climate Change in Ohio
  • Increase in temperature by 2-3 degrees C
  • Increase in harmful radiation
  • Increased rainfall 20- more?
  • Decrease in underground water storage
  • Increase in weather events (floods, droughts)
  • Increased use of coal ---increase in acid rain

3
Global Precipitation (IPCC,2008 report)
4
Moores 3 Research Sites
  • Nakada, Miyagi, Japan Watershed---rice belt--
  • OhioSugar Creek Watershedmixed animals and
    crops
  • Ohio---Upper Scioto Watershedcorn and soybeans

History of Water Use in the Nakada Watershed,
Japan last 100 years
  • Increased the levee height to avoid flooding
  • Increase of paddy size from 10 ares to 1 hectare
    size
  • Destruction of wetlands (conversion to rice
    paddies in 1908)
  • Direct irrigation and drainage to rice paddies
  • Increase in crop varieties that respond well to
    chemical fertilizers. Decrease in heirloom
    varieties which are more generalized.

10
History of Water Use in the Sugar Creek Watershed
and Upper Sciotothe last 100 years
  • Tile drainage systems designed to get water off
    farms as quickly as possible
  • Straightening of streams by farmers
  • Destruction of wetlands
  • Underground storage of water has
    decreasedsprings are not flowing as much as 50
    years ago.
  • Dams created to prevent flooding of Ohio River
    creation of conservancy districts
  • Decrease of fallow cycle, decrease of crop
    rotations, increase in use of chemical
    fertilizersdrying of the soil, more runoff
  • Increase in crop varieties that respond well to
    chemical fertilizers. Decrease in heirloom
    varieties which are more generalized.

Interns found a (aquatic?) firefly larvae
underneath a rock . We are in the process of
identifying what it is. The stream unexpectedly
had the lowest temperature of all of our streams
(16 degrees C) due to numerous springs. Site 7I
had total N of 18 and total P 0.23.
20
Salamanders
Macro inverts
Two very strong indicators of a healthy, Class
III stream are the presence of salamander larvae
and a high level of macro invertebrate
diversity Something about that zone on the map
must be influencing the one or both of the
biological indicators Perhaps physical
characteristics of the landscape, such as
headwater drainage area or average stream
gradient?

focus
  • NATURAL AND SOCIAL SCIENTISTS TEAMED TOGETHER
  • RESEARCHERS TEAMED WITH FARMERS (SELF-SELECTED)
  • FARMERS INQUIRY RESULTED IN NEW INQUIRY BY
    RESEARCHERS
  • FARM LEVEL DATA RESULTED IN FARMERS BECOMING
