This series of studies initially aimed to develop a scale to measure the motivation, based on the self-determination theory, of rural farmers in Madagascar toward an agricultural training program. Considering the low rate of literacy, the Likert scales were designed to be administered orally. However, there were several unforeseen challenges in psychological measurement that hindered the development of the scales. Despite several revisions, responses to the questions lacked sufficient variance for the first four studies. The scale produced in the fifth study attained marginally satisfactory variance and internal consistency. The final version of the scale asked questions in the second person and measured the respondents’ frequency of thoughts, instead of their degree of agreement with a first-person statement as is common in many scales. The possible reasons behind the lack of variance when answering in degrees are discussed. The challenges involved in the quantitative psychological measurement of impoverished populations, as well as considerations for future research in poverty contexts are also discussed.

To determine the effects of recent warming trends on agricultural production in Japan, in 2003 and 2005, surveys of the public institutes of agricultural research in 47 prefectures were conducted. The results suggest that recent warming trends have already significantly affected nearly all types of crops and livestock in Japan. All 47 prefectures reported warming effects on fruit tree cultivation and over 70% of prefectures recognized the effects on rice, vegetable and flower cultivation. Horticultural crops and rice are likely to be more sensitive to global warming than other agricultural crops and livestock. Our survey elucidated many effects of recent warming, such as phenological changes in many crops, increases in fruit coloring disorders and incidences of chalky rice kernels, reductions in yields of wheat, barley, vegetables, flowers, milk and eggs, and alterations in the type of disease and pest.
