“…There is no direct concern about whether plant populations can successfully migrate through fragmented landscapes, rather the concern is whether farmers will be able to identify and acquire crop genotypes that are adapted to their changing climates (8,31,45,54,122,132,134). In traditional agricultural settings, another problem is whether in situ conservation of traditional land races can be meaningfully maintained when local conditions change too rapidly and whether populations of wild crop relatives will be outcompeted by other species better adapted to the new climate.…”

Research in the effects of climate change on plant disease continues to be limited, but some striking progress has been made. At the genomic level, advances in technologies for the high-throughput analysis of gene expression have made it possible to begin discriminating responses to different biotic and abiotic stressors and potential trade-offs in responses. At the scale of the individual plant, enough experiments have been performed to begin synthesizing the effects of climate variables on infection rates, though pathosystemspecific characteristics make synthesis challenging. Models of plant disease have now been developed to incorporate more sophisticated climate predictions. At the population level, the adaptive potential of plant and pathogen populations may prove to be one of the most important predictors of the magnitude of climate change effects. Ecosystem ecologists are now addressing the role of plant disease in ecosystem processes and the challenge of scaling up from individual infection probabilities to epidemics and broader impacts.

“…In the past three hundred years, the food system has dramatically altered the Earth's atmospheric conditions, primarily through the release of carbon dioxide from clearing land for food production, methane from rice and livestock, and nitrogen dioxide from fertilizer (Smith & Almaraz, 2004;Ingram et al, 2010). Agricultural systems may also pollute nearby ecosystems by releasing nitrites, nitrates, and chemicals into water streams (Ortiz et al, 2013).…”

AcknowledgementsThe community members of Panaillo taught me so much that extends far beyond this research and have inspired me to work harder and to be better. I deeply appreciate their friendship, their faith, and their endless supply of paranta shui. The quality, scope and meaning of this research are a direct result of their hard work. I am extremely grateful to my supervisor, Dr. James Ford, for serving as an invaluable mentor to me for several years. He introduced me to the concepts and politics surrounding climate change adaptation and has inspired me to continue working in this field for many years to come. He taught me to think critically about my own work and the work of others and I admire his commitment to community engagement and to resolving these 'wicked' problems. Through his guidance and example, I have learned how to make meaningful impacts in climate change adaptation research and I truly appreciate the freedom he has given me in carrying out this research.

“…The impacts of climate change on agriculture are likely to result from the effects of rising CO 2 on plant growth, warmer and drier conditions, changes in wind speed, insect and plant disease pressures, and many more subtle changes resulting from altered interactions among components of crop agro-ecosystems (Smith & Almaraz 2004); however, those impacts which cause losses in crop yield have generally been ignored (Lim et al 2004, Scherm 2004. Increasing CO 2 and other greenhouse gases are likely to have serious implications for global climate systems and to cause a series of novel environmental changes, predominantly through anthropogenic activities (Allen 1990, IPCC 2001, McMichael 2001, Centritto & Loreto 2005.…”

Yield and growth criteria of irrigated and rainfed sunflower Helianthus annus and chickpea Cicer arientinum were studied under simulated climate change for Tabriz in Iran. Monthly average temperature and rainfall under doubling CO 2 were predicted using Goddard Institute for Space Studies (GISS) and Geophysical Fluid Dynamics Laboratory (GFDL) models. The effects of climatic change on crop growth period, yield components and water requirements of those crops were evaluated by a crop simulation model (OSBOL). Based on GISS and GFDL predictions, with doubling CO 2 concentration, mean annual temperature for Tabriz increased by 4.6 and 4.3°C, respectively. The results obtained by GISS showed that doubling CO 2 will lead to an increase in mean temperature of 3.7°C, and a 40% increase in mean rainfall, during the first 5 mo of the year. However, GFDL predicted an increase of 4.7°C in mean temperature and a reduction of 12% in mean rainfall during the first 5 mo of the year. According to OSBOL under GDFL predictions, the period from sowing to maturity and harvest index were reduced by climate change, whereas yield, biomass and water requirement for irrigated sunflower were increased. The biomass for rainfed sunflower increased, while days to maturity and harvest index were reduced. Yield predictions of OSBOL based on GISS contrasted with those based on GFDL. Doubling CO 2 caused a reduction in days to maturity, biomass, yield and water requirements for irrigated chick pea. The number of days to maturity for rainfed chickpea was reduced and harvest index, biomass and yield were increased due to climate change.
