David Zilberman ARE PP 253
The Feasibility and Management of Sink Activities
Movement of warmer climate from the tropics to the Poles
Mexican climate will migrate to California.
California climate will migrate to Oregon.
Most of Texas and Oklahoma will become a desert, and some areas in Canada will increase in productivity.
Increased snow melt,flooding and changes of volume and timing of irrigation water
Hot crop near equator,cold one near poles.
With CC movement to the pole,settlement close to poles transition from cold to hot,desertification
Fertilization effect: Higher levels of carbon will increase yield.
Daylight effect: Moving north will reduce exposure to the sun and reduce yield.
Pest effect: Warmer climate will lead to northward movement of pest and reduce yield.
Protein effect: Increase in carbon will lead to higher yields but less protein production.
Slow and costly adjustments
Incentives to develop capacity to deal with CC
Many developing countries oppose it for several reasons.
Nation’s emissions limits are proportional to population.
National emission limits are based on a formula that combines 1990 emission base and population size.
Nations have sovereignty for domestic implementation
Joint implementation projects in countries that sign the agreement. Such projects may enable countries to invest in low-cost, emission- reduction activities or provide a foundation for trading.
Clean Development Mechanisms (CDMs) are emission reduction projects in LDCs that will provide credit to the developed nations that finance them.
Monitoring of sink activities is difficult. Carbon flow measurement is impossible--need to measure proxies.
Pay based on crop and technique selection
Contribution depends on past activities-need base line measurement
Establishment efficient institutional set up-
