Amount of Stream Flow=Fresh Water 2081 to 2100 From IPCC AR5 2013DRYIssues in LocationsLocation and Availability of WaterStream Flow will be affected by Climate ChangeGround Water has different CharacteristicsTurkey, Spain, Portugal, Italy will be dry.In Japan, not so much difference.Temperature will affect most of suitable agri. products. Special Products in the area will be affected.Apples in Nagano -> Pairs in Nagano?Grapes and Wineries in Europe already receive some changes. Germany will be the best place??

43In most cases, Some kinds of Adaptations are required.Water Dependence on Snow or Ice of Glacier - High MountainsSnow or Ice in winter play role of ReservoirIn spring, water from snow melt used for agricultureClimate Change -> Early snow melting in winter -> No water reservoir for Agriculture This tendencies already apparent in Himalayan or Tibetan Region and similar in Andean AreaAdaptation : To construct new water reservoirs for Agriculture4445

Fragility is high in water supply in High MountainsImportant to keep less than 2 degree 22Fertilizer IssueNitrogen FertilizerHarbor-Bosch Process success to make Ammonia from Nitrogen and HydrogenHuge Energy ConsumptionMore than 1% of Global Energy Consumption Side Effects of Excessive Use=Over-fertilizationPollutant to Underground WaterEutrophication(Nutrient Enrichment) of Lake and River WaterIncrease N2O(one of GHG) emission from Patty Fields MUST: Appropriate Use of Nitrogen Fertilizer4620 Michel & FAOSo called global population explosion depended onthe increase in grain production, which is expressed in unit crop (t/ha). French Wheat Michel & FAOPhosphorous Fertilizer P as PhosphateInevitable For All Plants: To be used Nucleic Acids, ATP and membrane lipids.Guano from Nauru, Depleted : Guano is a highly effective fertilizer due to its exceptionally high content of nitrogen, phosphate, and potassium, three nutrients essential for plant growthP : Exist as a major component of the Earth. No.11 in the scale of abundance.F : Coexisting F may be a problem. F is No.13 in the scale of natural abundance.

50Sustainability of SoilMaintenance and improvement of soil quality in continuous cropping systems is critical to sustaining agricultural productivity and environmental quality.Asian Rainforest are old and poor in minerals whereas the soils of the western Amazon (Ecuador and Peru) and volcanic areas of Costa Rica are young and mineral rich.Change in Rainfall may affect the status of soil, i.e. mineral contents and contents of organic components.

51Shortage in Food Supply? 1. Insufficient Agriculture Field More than 1-2m of Sea Level RiseLarge Scale of Loss of Agricultural Land in several countriesResident Area may be lost. -> Environmental Refugees -> Decrease in Food SupplyDraught in Turkey, Spain, USA, AustraliaProduction of Wheat and other crops will decrease.Local Temperature ChangeChange in Suitable Crops -> Decrease in SupplyFields optimum to certain crop move to colder area. Is it possible for farmers to move?

5222. Severe safety requirement by citizens/consumersGMO(genetically modified organisms) Issues for Soy, Corn etc.Is it Safe? Yes, safe if eaten.Any environmental adverse side effects? Any abrupt change in productivity of crop?As Japanese consumers, everybody wants to have Zero Risk environment without any Agrichemicals.Yield may be go down.Even if Agrichemicals are safe for human, but is it safe for insects to help pollination?

53Adaptation with Skilled ForecastAverage Rain Fall = Slight IncreaseTemperature will go up to some extentAgricultural Suitability of certain place will be changed, but the other place will become good land for agriculture. CO2 concentration increase =Some fertilizing effect

Area of farming land is about half of land suitable for agriculture. If enough farmers in the new agricultural land, global supply of food will be enough.


It is a good strategy to have long perspectivesof the global changeas possible as we can, if we try to prepare forunexpected changes of local situation.

55Theoretical GoalTo realize Steady State of the Earth in 2100.Three Conditions1:Renewable Resources : Use only the amount naturally renewed.2:Non Renewable Resources : Use No Energy resources. Recycle all Metals & Minerals perfectly using Renewable Energy. 3:Environmental Pollutant : Release only the amount within the capacity of the Earth.56More Detailed Description by Herman Daily in 19711. Renewable Resources: Do not use renewable resources at higher speeds than the speed of regeneration.Good for : Fishery, Forestry,etc.

3. Wastes: Discard wastes Only at a speed less than the speed of reduction by the capacity of the Earth.Including Nuclear Spent Fuel 57Continued2. Non-Re
