Alternative crops, with appropriate markets and infrastructure, provide farmers the potential for diversification to offset financial stress caused by an overabundant supply of a limited number of species grown over a broad area. The objective of this work was to develop a model that would identify where soil and climate conditions are likely to be suitable for a large number of crops over a large geographic region. The model was used to screen 414 crops for suitability to Illinois conditions. The 414 crops were a subset of 968 candidate crops, for which crop soil (texture, pH, drainage) and climate (temperature, precipitation, growing season length, minimum winter temperature) requirements were identified from a literature search. The simple model was linked to geographic information system software to evaluate the suitability of the soil and climate conditions of Illinois. Two of the 414 crops were classified as highly suitable in more than 50% of the state's land area, 18 suitable in more than 90% of the state, and a total of 83 crops were rated as suitable to highly suitable in more than 90% of the state. Comparison of the suitability maps to known ranges of existing crops, and limited evaluation of 15 crops classified as suitable, moderately suitable and unsuitable for Urbana, Illinois conditions in a demonstration plot, showed this model's utility to a limited area, and suggests that the model can be applied to any region where geographically referenced soil and climate data either exist or can be developed.

Background: The study was conducted to examine the relationships between functional decline, health risk factors, lifestyle practices, and demographic variables in two culturally diverse, community-based samples of White and Japanese American older adults. Design: The study was an analysis of data from two ongoing studies of aging and dementia in King County, Washington. Functional status at baseline was evaluated, and factors associated with functional decline over a 4-year follow-up period were identified. The sample included 1,083 Japanese American and 1,011 White cognitively intact, community-dwelling adults aged 65 and older, who had no functional limitations at baseline and participated in at least one follow-up examination. Results: In 4 years of follow-up, 70% of the subjects reported no increase in functional limitation, and fewer than 5% of subjects declined in five or more activities. Risk factors associated with functional decline included increased age, female gender, medical comorbidity (particularly cerebrovascular disease, arthritis, and hypertension), elevated body mass index, poorer self-perceived health, and smoking. Depression and diabetes were also significant for persons with the greatest functional decline over the 4-year follow-up. Japanese speakers were significantly less likely to decline over the follow-up period than White or English-speaking Japanese American subjects. However, Japanese speakers were more likely to discontinue participation during the follow-up period, and may also have been more likely to underreport symptoms of functional decline. Conclusions: The present study provides further support that healthy lifestyle practices and prevention of chronic disease are important for maintaining functional independence in older adults. Japanese-speaking subjects were less likely to decline over time, although this could be due in part to differential dropout and reporting bias. These findings have important implications for the design and interpretation of longitudinal studies of older adults. Researchers interested in the effects of ethnicity on health and aging should be cognizant of differences in recruitment and enrollment strategies among studies, and the ways in which these affect study findings. This study also demonstrates the importance of devoting adequate resources to minimize dropouts, and of including measures of health and functioning that are culturally equivalent and less reliant on self-report data.
