22 pages, via online journal, Past explanations of why rural people respond as they do to external development interventions have emphasized the role of key limiting factors or critical characteristics (wealth, education, land tenure, etc.) which are thought to influence peoples' behavior in predictable ways. Efforts to promote tree planting and soil conservation in eight neighboring villages in the Philippines revealed that variation in participation did not reflect clear patterns based on existing household or village characteristics. Instead, specific responses to interventions reflected a complex, but interpretable interaction between existing socio-economic factors and historic trends or events. Characteristics like the degree of local knowledge, security of land tenure and community cohesion affected peoples' participation, in general, but their specific influence was neither predictable nor consistent between, and even within, individual villages. An appreciation of the specific historic context was often sufficient to explain these variations. The following historic trends and events were found to have important consequences for peoples' participation: migration and settlement history; family and group lineages; history of socio-political organization and conflict; history of physical isolation; labor history; economic–ecological history; environmental history; and past exposure to development agents. The paper concludes with a preliminary checklist of questions intended to assist researchers and development agents to discover relevant and interesting historical information about rural villages.
12 pages., via online journal., Effective communication of risks involved in the climate change discussion is crucial and despite ambitious protection policies, the possibility of irreversible consequences actually occurring can only be diminished but never ruled out completely. We present a laboratory experiment that studies how residual risk of failure of climate change policies affects willingness to contribute to such policies. Despite prevailing views on people’s risk aversion, we found that contributions were higher at least in the final part of treatments including a residual risk. We interpret this as the product of a psychological process where residual risk puts participants into an ”alarm mode,” keeping their contributions high. We discuss the broad practical implications this might have on the real-world communication of climate change.
7 pages., via online journal., Pesticide use and pesticide residues in foods have been the subject of controversial public discussions and media coverage in Germany. Against this background, a better understanding of public risk perceptions is needed to promote efficient public health communication. To this end, this study captures the German public's perception of pesticide residues in foods. A representative sample of the population aged 14 years and older (n = 1,004) was surveyed via computer-assisted telephone interviewing on their attitudes and knowledge with regard to pesticide residues. Based on questions regarding their typical consumer behavior, respondents were classified into conventional and organic consumers to identify differences as well as similarities between these two consumer types. As assessed with an open-ended question, both organic and conventional consumers viewed pesticides, chemicals, and toxins as the greatest threats to food quality and safety. Evaluating the risks and benefits of pesticide use, more than two-thirds of organic consumers (70%) rated the risks as greater than the benefits, compared with just over one-half of conventional consumers (53%). Concern about the detection of pesticide residues in the food chain and bodily fluids was significantly higher among organic compared with conventional consumers. Only a minority of respondents was aware that legal limits for pesticide residues (referred to as maximum residue levels) exist, with 69% of organic and 61% of conventional consumers believing that the presence of pesticide residues in foods is generally not permitted. A lack of awareness of maximum residue levels was associated with heightened levels of concern about pesticide residues. Finally, general exposure to media reporting on pesticide residues was associated with more frequent knowledge of legal limits for pesticide residues, whereas actively seeking information on pesticide residues was not. The possible mechanisms underlying these findings are discussed.
24 pages., Via online journal., We examined the relationship between attitudes toward urban ecological restoration and cognitive (perceived outcomes, value orientation, and objective knowledge), affective (emotional responses), and behavioral factors using residents of the Chicago Metropolitan Region. Positive and negative attitudes were both related to perceived outcomes of ecological restoration. In addition, positive attitudes were related to values while negative attitudes were related to emotions. Attitudes of high and low importance groups were connected to perceived outcomes of ecological restoration; however, attitudes of the high importance group were also related to values, emotions, and behavior. Positive and negative attitude groups differed on perceived outcomes, basic beliefs, knowledge, and behavior. Implications lie in understanding of complex attitudes toward natural resource issues and improved communication efforts to influence or educate the public.
11 pages., Via online journal article., As climate change is expected to significantly affect agricultural systems globally, agricultural farm advisors have been increasingly recognized as an important resource in helping farmers address these challenges. While there have been many studies exploring the climate change belief and risk perceptions as well as behaviors of both farmers and agricultural farm advisors, there are very few studies that have explored how these perceptions relate to actual climate impacts in agriculture. Here we couple survey data from United States Department of Agriculture farm service employees (n = 6, 514) with historical crop loss data across the United States to explore the relationship of actual climate-related crop losses on farm to farm advisor perceptions of climate change and future farmer needs. Using structural equation modelling we find that among farm advisors that work directly with farms on disaster and crop loss issues, there is a significant positive relationship between crop loss and perceived weather variability changes, while across all farm advisors crop loss is associated with reduced likelihood to believe in anthropogenic climate change. Further, we find that weather variability perceptions are the most consistently and highly correlated with farm advisors' perceptions about the need for farm adaptation and future farmer needs. These results suggest that seeing crop loss may not lead to climate change belief, but may drive weather variability perceptions, which in turn affect farm adaptation perceptions. This lends further evidence to the debate over terminology in climate change communication and outreach, suggesting that weather variability may be the most salient among agricultural advisors.
28 pages, via online journal, While uncertainty is central to science, many fear negative effects of communicating scientific uncertainties to the public, though research results about such effects are inconsistent. Therefore, we test the effects of four distinct uncertainty frame types (deficient, technical, scientific, consensus) on three outcomes (belief, credibility, behavioral intentions) across three science issues (climate change, GMO food labeling, machinery hazards) with an experiment using a national sample (N = 2,247) approximating U.S. census levels of age, education, and gender. We find portraying scientific findings using uncertainty frames usually does not have significant effects, with an occasional exception being small negative effects of consensus uncertainty.
