16 pages, Plagued by recent and historic drought, the need for water storage and management solutions in California is apparent. As a potential solution, the Sites Reservoir project offers an opportunity to a state eager to conserve and better manage water. The Sites Reservoir project involves complexities from a variety of standpoints and stakeholder perspectives. This study investigated the frames and sources used by The Sacramento Bee to communicate about the Sites Reservoir project over a 10-year period. The most frequently used frames throughout the dataset were “policy and government” and “water conscious,” and the sources most frequently utilized for information about the project in the articles were elected officials, government agency representatives, and nonprofit representatives. The findings suggest water management is linked with political activities and supports the assertion that the media tend to focus on the role of policy and political opinion in water management issues. At the same time, the findings suggest the need for water solutions is evident, given the prominence of the “water conscious” frame. Future studies should evaluate frames over time, and investigate the potential nuance between frames used to communicate about water management in different areas of the United States facing water management issues.
34 pages, Agricultural nitrogen (N) use is a major contributor to environmental problems arising from nitrous oxide emissions and N loading to groundwater. Advances in the adoption of conservation practices requires a better understanding of the agronomic context for cropping systems. This paper tests hypotheses about how agronomic and knowledge barriers influence the adoption of conservation practices for N management in orchard agroecosystems. Agronomic barriers are characterized by farm size, irrigation systems and access to water resources, and knowledge barriers are influenced by the availability of information and use of information sources. Our study focuses on the California’s San Joaquin Valley where we collected 879 in-person surveys from fruit and nut growers focused on ten different conservation practices related to fertilizer use, irrigation and soil health. We used logistic regression models to identify parameters influencing adoption and differences in adoption between fruit and nut growers. Our results indicate that overall growers report higher adoption for practices for fertilizer use compared to irrigation and soil health. Growers with larger parcels, microirrigation and more water security had a higher probability of practice adoption. Nut crops are more agronomically intense than fruit crops requiring higher rates of N fertilizer and water use. Nut growers adopted significantly more practices than fruit growers, and also utilized significantly more information sources and experienced significantly fewer practice challenges. Our results collectively support our hypotheses that agronomic and knowledge barriers differ between fruit and nut growers, and help to explain the variance in adoption of conversation practices in orchard agroecosystems. Furthermore, the significance of our work offers a case study for other regions and agroecosystems to address the need for linking agronomic and knowledge barriers to adoption in an effort to promote global climate-smart and regenerative agriculture initiatives.
13pgs, The Extension Service is one of many agencies charged with increasing awareness and knowledge of research-based agricultural conservation practices. A regional survey of Extension agents with agriculture and natural resources responsibilities was conducted to assess the need for in-service training on 11 water resource conservation topics. The highest priority training needs were for topics related to complex interactions and drivers of agricultural water pollution. This article highlights the implications of these results and offers broader perspective on bringing the Borich model of needs assessment into the agricultural and natural resources realm of subject matter expertise.
11 pages., Worldwide drought has significance and continues to pose long-lasting effects on the agricultural sector, including South Africa. The recurring drought is a major challenge to smallholder livestock farmers in the Northern Cape Province of South Africa. This study assesses the perception of smallholder livestock farmers towards agricultural drought resilience. The study utilised a perception index score using primary data collected from 207 smallholder livestock farmers following a structured questionnaire survey and multistage sampling procedures. The study found that the average perception index of the role of social networks and government to enhance agricultural drought resilience was negative, which implied that their role in enhancing resilience towards agricultural drought was insufficient. However, the perception of smallholder livestock farmers on the role of social networks was lower than the role of government. This study recommends coordination and cooperation amongst all role players to reinforce strategies to enhance smallholder livestock farmers’ resilience. This includes coordinator amongst the local, provincial government, African Farmers’ Association of South Africa, extension officers, private sectors, monitoring agencies in terms of reliable early warning information and communication amongst decision-makers. Collaboration amongst government departments at the national and provincial levels should be strengthening to enhance farmer’s resilience. The collaboration includes the Department of Agriculture, Forestry and Fisheries at the national level, Provincial Departments of Agriculture, National and Provincial Disaster Management Centres, South African Weather Service and Department of Water Affairs. Smallholder livestock farmers’ awareness of the significance of social networking and government participation should be promoted.
17 pages, For news media on the earth's driest continent, changes in the health and politics of Australia's largest river system, the Murray-Darling, have been a major national focus for decades. In recent times, climate crisis, drought and policy failure have combined to threaten its future, putting the issue under intense public scrutiny. This article offers a critical discourse analysis of specialist rural radio coverage of the issue in 2018–19. It identifies the discourses that the Country Hour program presents and considers the voices and viewpoints that are absent. Two critical discourse moments are analyzed: an ecological disaster in which more than one million fish died, and #watergate – a pre-election scandal over commercial water rights. We map the strategies and roles of Country Hour journalists and other social actors in legitimating the “productive use” of the river system above all else, politicizing the issue and shifting responsibility for the river's wellbeing.
4 pages, via Online journal, Bougainvillea (Bougainvillea sp.) plant inflorescence number will vary in response to multiple cues such as changes in temperature, water, light intensity, pruning, and photoperiod. Previous research reports that the application of plant growth regulators (PGRs) to bougainvillea grown under varying photoperiods improved inflorescence number, probably as a result of changes in gibberellic acid (GA) levels. There are many bioactive plant GAs, but we chose to investigate differences in gibberellic acid 3 (GA3) levels and inflorescence number in response to the application of ethephon (2-cholorethylphosponic acid) or abscisic acid (ABA) to ‘Afterglow’ bougainvillea (Bougainvillea ×buttiana) grown under 14-hour photoperiod [long-day (LD)] conditions. Plants were 5 inches tall with seven visible lateral nodes and were grown in a greenhouse in 4-inch pots filled with 5-mm coarse aquarium zeolite. Ethephon was applied as a foliar spray at 0.05, 0.07, 0.10, 0.15, or 0.20 mg/plant. ABA was applied as a soil drench at 1, 1.5, 3, 6, 8, or 10 mg/plant. Endogenous levels of GA3 were measured 1 and 48 days after treatment to calculate the change in GA3 (∆GA3). A short day (SD) control of 8 hours was included to measure differences in inflorescence number and ∆GA3 between photoperiods. ‘Afterglow’ plants grown under SD conditions had the greatest decrease in ∆GA3 (–1.09 µg·g–1) over 48 days and the most inflorescences (10.6) compared with LD control plants with a decrease in ∆GA3 of –0.09 µg·g–1 and fewer inflorescences (1.0). Plants grown under LD conditions and treated with 0.05 mg/plant ethephon had inflorescence numbers (9.6) and levels of ∆GA3 (–0.74 µg·g–1) similar to the SD control. As ethephon rate increased to more than 0.05 mg/plant, inflorescence number on LD plants decreased and ∆GA3 increased. Exogenous ABA rates of 1 mg/plant produced inflorescence numbers (1.4) and ∆GA3 (–0.10 µg·g–1) similar to the LD control. As the rate increased, ∆GA3 increased and inflorescence number decreased. Plants treated with ABA rates of 3 mg/plant and more were defoliated and had no inflorescences.

Developments highlighted lack of trust and mutual goal-seeking.
9 pages., Online via publisher., An adapted health-branding framework guided the 3-step mixed-methods approach to identify evidence for campaigns using a scoping review, comprehensive literature review (1990-2016), and key-informant interviews. Results showed that industry, government, and non-governmental organizations supported 13 campaigns that used various health-branding strategies.
12 pages, Many environmental dilemmas such as water scarcity originate from human behavior. This study aimed to analyze Iranian farmers’ water conservation behavior using Bandura’s social-cognitive theory. To this end, a cross-sectional survey was conducted to collect the required data. The research instrument was a questionnaire. A sample of 380 farmers was selected using a multistage stratified random sampling method. The results indicated that variables of social-cognitive theory could predict about 73% of farmers’ water conservation behavior variance. Investigation of direct effects of factors on farmers’ water conservation behavior revealed that the major determinants are as follows: intention of water conservation, social-structural factors, perception of others’ behavior, outcome expectancy, self-efficacy, and water conservation co-regulation. Findings showed that factors that have been mentioned in social-cognitive theory could be considered for enhancing farmers’ water conservation behaviors since the theory provides a more realistic insight into farmers’ behaviors with an emphasis on farmers’ social and structural contexts

22 pages., Via online journal., Purpose: This study explores the use of advisory services by farm managers and its linkages with the economic, environmental and social performance of farms.
Design/methodology/approach: Using cluster analysis we determined groups of farms according to their sustainability performance and explored the correlations between contacts with advisory services and a set of farm-level sustainability indicators.
Findings: There exist significant differences in the number of farmers’ contacts with advisory services across countries, type of farms, farmers’ degree of agricultural education, utilized agricultural area, legal type of farm ownership and economic size of the farms. We identified three groups of farms that have different sustainability performance, are different in farm characteristics and relate differently to advisory services. The number of contacts with advisory services is positively related to the adoption of innovations, the number of information sources utilized and the adoption of farm risk management measures. We find no clear linear relationship between advisory services and environmental sustainability.
Theoretical implications: This study derives hypotheses to analyze causalities between indicators of farm-level sustainability and advisory services.
Practical implications: Results suggest the importance of taking into account the heterogeneity of farming systems for the design, targeting and evaluation of advisory services. In addition, results confirm the importance of selection of indicators that can be used in multiple sites.
Originality/value: We used a harmonized indicator of advisory services and a harmonized set of farm-level sustainability indicators in nine different EU countries that could be used to evaluate the role of advisory services in the achievement of multiple objectives in different groups of farms in multiple sites.
