NS 435 Unit 2: Impact of Ecological Changes on Agriculture. Lei Wang, Ph.D. How Ecological Changes Affect Agriculture/Food Production? Short-Term Effects Long-Term Effects How Modern Agriculture Impacts the Climate? Alternative Solutions/Opportunities?. Outline.
Lei Wang, Ph.D.
According to Siikamaki, (2006) “Agriculture is frequently discussed in the context of climate change: not only is agriculture vulnerable to climate change, it is also part of the problem and its potential solutions.”

According to Peter Backlund from NCAR, discussed in the context of climate change: not only is agriculture vulnerable to climate change, it is also part of the problem and its potential solutions.”
“Human activities have altered the global climate.
During the 20th century, the global average surface
T increased 0.6 C and global sea level
increased 15 to 20 cm.”
“… human influences will continue to change Earth’s climate throughout the 21st century. The global average T will rise another 1.1 to 5.4 C by 2100. Which will result in continued increases in sea level and overall rainfall.”
- however, with continued temp increase (esp. Southern regions) some crops may not adapt.
- Northern regions may benefit most (since tend to be cooler.) e.g. longer growing season opportunity.
-- Possible to grow new crops/different crops.
Questions? many parts of the globe by 2080-99. The largest decreases are projected across the northwest parts of Europe and North America.
