of low-quality humanitarian food assistance, impaired livelihoods, volatile and rising food prices, and food system instability, among others ( Asch et al. 2018 ; Barnett 2011 ; Bell et al. 2016 ; Campbell 2015 ; Campbell and Warrick 2014 ; Savage et al. 2020a ; Taylor et al. 2016 ). These effects are likely to exacerbate the current shift away from diverse, minimally processed diets, to a lower-quality diet high in fat, sugar, and salt and increasing prevalence of diet-related NCDs such as

. Ascertaining the perceived challenges and opportunities to implementing programming is important to increase the likelihood of successfully encouraging behavior change ( Burke 2002 ). The current study addresses this need by exploring the barriers and priorities that researchers and Extension professionals at land-grant universities in the northeastern United States perceive in translating scientific information into useful programming for agricultural and natural resource audiences. While many previous

’ perceptions of climate or weather ( Fitchett and Hoogendoorn 2018 ). Sentiment analysis of online reviews may provide new data and methods for researching tourists’ perceptions of climate and weather. China has diverse climates and weather that range from frigid to tropical ( Zhang 1991 ). Most areas are currently negatively affected by climate change. In 2018, the number of domestic tourists in China was 5.539 billion, and the number of outbound tourists was 150 million, ranking first in the world

). The widely used Palmer drought severity index (PDSI) contains information about antecedent and current soil moisture ( Alley 1984 ) and is computed from 1901 to 2009 ( Van der Schrier et al. 2013 ). The two precipitation minus evaporation indices, which describe the deficit of soil moisture were developed by Felzer et al. (2020) from monthly temperature, precipitation, and Penman–Monteith potential evapotranspiration (PET_pm) data from 1901 to 2014. One version of the precipitation minus

Adger 2017 , p. 43). Disciplinary boundaries have resulted in different conceptualizations of resilience with few attempts to provide interdisciplinary insights on how human resilience is shaped ( Smith et al. 2014 ) that correspond to a great opportunity for improving current knowledge, which this research embraces. As a result, several authors have made the case for assessing general and specified resilience ( Waters and Adger 2017 ; Berkes and Ross 2013 ; Folke et al. 2010 ). The approach taken

temperature in Taiwan increased by 0.1°C every 10 years from 1880 to 2018, and this number boosted to 0.24°C from 1990 to 2018, based on the Central Weather Bureau (CWB). The temperatures are forecast to increase worldwide in the future. According to the Intergovernmental Panel on Climate Change ( IPCC 2018 ), human activities are estimated to have caused 1°C of global warming above preindustrial levels. If global warming continues to increase at the current rate, it will reach 1.5°C in 2030 at the

added). Given the apparent urgency of climate risks in southern Africa, coupled to a suite of growing stresses, it may indeed be useful to carefully reexamine past and current institutional dimensions underpinning climate risk reduction, but then also, and this is more critical, to begin to urgently find ways to effectively live with drought: Meanwhile conditions have been steadily getting worse and to-day the Commission sees the results of inaction on every hand. Frequently, on asking for

Location information can be communicated via text or images, including maps, which provide a visual means of determining whether one is susceptible to the threat ( Liu et al. 2017 ). 4

1. Introduction Crop genetic diversity is a key factor for long-term viability and adaptation to changing environmental conditions ( Hammer and Teklu 2008 ). It prevents crop failure ( Altieri 1994 ; Vandermeer 1989 ), contributes to more resilient systems, and limits susceptibility to pests and diseases ( Tonhasca and Byrne 1994 ). A wide gene pool is essential for world food security and, as a source of materials for breeding new plant varieties, to mitigate current and future production

boundaries ( Hagenauer and Helbich 2013 ). These factors must be weighed in the interpretation since both the SOM and the cluster algorithms ultimately force an observation to join a particular node and cluster, and any changes to parameters will likely result in different versions of a similar pattern ( Budayan et al. 2009 ). c. Significance and implications for future research During the decade of study (2008–18), the rhetoric around climate change arguably shifted to the extremes ( Hulme 2019 ). As
