Title: Where will our food come from?


1
Where will our food come from?
  • A discussion of the need to preserve farmland in
    the Central Valley of California.
  • AGST 3000
  • Agriculture, Society and the Natural World

Overpowering Factor affecting Farmland
Preservation
Population and Urban Growth 58 Counties in
California

Central Valley 18 Counties (Shasta Kern )
42,000 square miles 450 miles long (ex.
Boston to Washington) 40-60 miles wide over
5.5 million population (2000)

San Joaquin Valley 8 Counties 27,276 square
miles 270 miles long 1- Northern San Joaquin
Valley (San Joaquin, Stanislaus, Merced) 2-
Southern San Joaquin Valley ( Madera, Tulare,
Kings, Fresno, Kern) Sacramento Valley (2
parts) Sacramento Metro - urban in
character North Sacramento Valley Land and
climate changes growing changes, uniqueness to
valleys and areas

  • Air quality bases (air region-basin)
  • Inversions and air flows

Remember California is the most productive ag
state ( 1 in production) San Joaquin valley
produces ½ of states total in its 8 counties 6
of 8 counties produce more than a billion
dollars/ year Entire Central Valley produces 2/3
of states production

  • Population growth consequence of economic
    changeopportunity for a better life
  • 70s 2000 characterized by
  • Technology advances
  • Cold war ending
  • Contributed to the expansion of exports
  • Valley
  • 1 low cost of living
  • affordable housing,
  • inland movement from coastal areas,
  • young families
  • 2 higher birth rates
  • 3 movement from abroad

17
  • Growth effects
  • More retail
  • Crowded
  • Pollution
  • More consumer choices
  • Faster population growth within cities
  • Racially and ethnically changing
  • Diversity increased in valley
  • Highest in Tulare, Merced, Madera, Fresno,
    Kings

valley (7 million) by 2040 What will that do to
Agriculture in the Valley? Fresno is 1 Ag

19
  • Should we protect our Ag Land?
  • Preserve open space
  • Pollution/environment
  • By policy, farmland should be protected
  • ( policy protects land, not farmer)

California AgricultureUrbanization
Between 1997 and 2002 California lost 8,282 farms
and 1,168,761 acres of farmland.
Census of Agriculture, 2002
22
Central Valley AgricultureUrbanization
6 of the top ten fastest growing counties in
California are in the Central Valley. All 7 San
Joaquin Valley counties made it into the states
top 20.
California Department of Finance 2003
23
Central Valley AgricultureUrbanization
From 1998-2000, the San Joaquin Valley led the
state as a region in conversion of irrigated
farmland to urban land- 8,072 acres (5,610 acres
were prime ag land).
FMMP, 2002
24
Central Valley HousingUnmet Housing Needs
  • At the recent rate of construction, the following
    percentage of housing needs will be unmet from
    2000 to 2010

Low Density Versus Higher Density Scenarios
28
How much land is being lost statewide?
  • 1992 199785,200 acresPrime farmland
  • Increase from the previous 5 year period15
  • 500,000 acres of total farmland lost from 1988 to
    1998
  • Could lose a million more by 2040
  • Conversion of prime farmland is 30 faster than
    non-prime farmland

29
Statewide Farmland Loss...
  • AFT classifies the Central California Valley as
    the most threatened farmland in the country
  • Urbanization could consume or indirectly affect
    over 3.6 million acres of irrigated land, more
    than half of the 6.7 million irrigated acres in
    the 11 counties that comprise the Central Valley
    floor (AFT survey)
  • Land converted to urban uses was 87,000 acres
    over a two year period 96-98.
  • 22 of all land converted to urbanization is
    prime farmland

30
Regional Picture
  • Regionally 10-11 of all prime farmland lost to
    urbanization in Valley
  • Converted to urban use! (1996-98)
  • Point is
  • Land is being developed at ever increasing
    rates---significant of prime farmland is being
    destroyed

31
State mapping project
  • designed to map Californias Land
  • -- Used to determine
  • 1 how much Ag land is lost
  • 2- what type of Ag land is being lost,
  • quality of soil, access to water

32
Farmland Mapping
  • Assessment of farmland loss is for urban or other
    uses
  • 48 (half) of all state land is mapped
  • 98 of farmland is mapped
  • Have to break down there are differences
  • 1. Quality of soil for growing
  • 2. Access to water (can land be irrigated?)
  • 3. Topography (ex. Flat or sloped)

33
Water access for irrigation very important in
classifying land.
  • Irrigation best of best ( most useful )
  • 1.5 million irrigated acres in California 62
    (941,000) is in the Valley

34
Six categories of land
  • 1. Prime Farm land
  • most productive soil (highest quality) linked to
    higher yields and irrigation
  • precious commodity
  • 2. Farmland of statewide importance
  • also irrigated land
  • Soil of slightly lesser quality
  • 3. Unique Farmland
  • irrigated or non-irrigated
  • soil less productive

35
Six categories of land continued
  • 4. Farmland of local importance
  • each county can determine or have power to
    designate
  • board of supervisors can protect
  • 5. Grazing land
  • livestock grazing
  • non-irrigated-poorest soil quality
  • 6. Urban
  • built up land
  • was farmland and now is used for
    residential/commercial

36
Prime Farmland
  • Best land is prime farmland
  • 50 of whole state 4.3 million acres is prime
    farmland
  • Out of 8.5 to 9 million acres of total farmland
  • In San Joaquin Valley 49 of this prime
    farmland is in our 8 counties. (2.1 mil)

37
Farmland catagories
  • 1- Prime farmland- 4.3 million
  • 2- Farmland of statewide Importance 2 million
  • 3- Unique 1 million
  • ½ of all 1,2,3 land is in our SJ Valley 8
    counties!
  • Why?...Soil, Water, Climate

38
As you recall
  • CA. Valley is losing thousands of acres of prime
    farmland.
  • Same trend in Stanislaus County
  • Look at all the subdivisions
  • Commercial development
  • Retail
  • Patterns of growth pose a threat in the Central
    Valley.
  • Potential for urban/rural conflict
  • Controlled growth?
  • County must approve new cities, growth boundaries
    and annexations

39
Zone of conflict is urban edge
  • For ExampleN. Modesto- McHenry
  • car dealer alley
  • ¼ community residential
  • ¼ transportationroads
  • ¼ jurisdiction to point of saleretail sales
  • ¼ Ag land now or ???

40
Interest statewide to protect prime farmland..
  • What are the options?
  • 1. Use regulatory powers of gov. (police power)
    to conserve land available (Green belts,
    environmental sensitive areas, Ag buffer zones)
  • 2. Use of special regional agencies that have
    control over boundaries of communities to protect
    farmland (Planning Commission).

41
More options?
  • 3. Use tax incentives for landowners and local
    govs. to conserve local land (Williamson Act)
  • 4. Use of innovative non-government tools to
    preserve land (transfer of developers
    rights/purchase of conservation easements).
  • Farmland Trust
  • 5. Linking of ag conservation to local economic
    development clusters promotes better economic
    value (business)

42
Even more options?
  • 6. develop new ways of planning urban areas
    smart growth into less prime land (General
    Plan)
  • 7. Sustain environment, encourage greater public
    involvement(initiatives on the ballot, Ag buffer
    zones, Green belts)
  • best prime farmland is on boundaries of cities.
  • It lands on the edge - zone of conflict
  • keeps pushing the line (who?)

43
Local Zoning
  • Divides jurisdiction into parts (zones)
  • Establishes what is permitted, prohibited,
    permitted with permits
  • What happens if you change zoning (rezoning)
    controversial with property rights

44
How to zone to protect ag?
  • Set up special Ag buffer zones (typically in
    counties) ie. Turlock, Merced, Ceres
  • Set minimum parcel size, not to go below a
    certain acreage (1, 5, 10, 20, 40)
  • Minimum parcel sizes have increased over the
    years to restrict rural development and farmland
    conversion

Journal
  • After reading the articles from the web and
    considering our conversation in class answer the
    following
  • In your opinion, do you think we should be
    concerned about the loss of agriculture land and
    why?
  • In your opinion, what are the most promising
    options or tools to deal with this issue and why?
  • Do you think that it is a viable alternative to
    allow our food source to be outside the United
    States and why?
  • What is your general opinion concerning the class
    discussion on this issue?
