A geospatial and quantitative analysis of agricultural exemption passes during the California wildfires

Background Climate change is anticipated to have profound effects on human health including infectious diseases. Wildfires have increased in frequency and intensity due to changes in precipitation and have been linked to worsening respiratory infections. We aimed to demonstrate whether an association existed between wildfire smoke and COVID-19 in California during 2020. Demographic data by county in California based on the 2020 American Census Survey and New York Times mask-use survey conducted in July 2020. The population of California is generally higher in the southern region, especially Los Angeles County. The median income is highest in the San Francisco Bay area. The outdoor laborer rate is generally higher in northern California, especially the rural county of Trinity. Self-reported mask use in July 2020 was high throughout the state, but lowest in the northern region. Methods We performed a population-based ecologic cohort study in California in 2020 using a spatial autoregressive model to test for associations between wildfire smoke and COVID-19 case and death incidence while adjusting for demographic and environmental factors. The counties of California were the units of analysis and all persons who lived in California were accounted for in the data. We used publicly available levels of particulate matter < 2.5 µm (µg/m3 PM2.5) specifically attributable to wildfire smoke in California during 2020. The median COVID-19 case and death incidence for each county in California and the overall case and death incidence in each county in California and the statewide county median case and death incidence is displayed in the first two plots below. The mean wildfire smoke PM2.5 exposure (µg/m3) in each California county and the median smoke exposure among California counties is displayed in the third plot. There was a surge in COVID-19 cases and deaths in California in the summer and winter of 2020 but a large degree of variation across counties. There was a surge in smoke exposure in the fall of 2020 and a large degree of variation across counties. Results In a model adjusted for spatial autocorrelation, environmental and demographic confounders, we found as smoke exposure increased per each 10 µg/m3 in PM2.5, there was an average increase of 175 COVID-19 cases/10,000 persons the following month (1-month lag) at the county level (P< 0.001) and an increase of 1.86 COVID-19 deaths/10,000 persons the following month at the county level (P< 0.001). These findings were attenuated in the 2nd month after smoke exposure where we found as smoke increased per each 10 µg/m3 in PM2.5 there was an average increase of 65.9 COVID-19 cases/10,000 persons the following 2nd month but no increase in deaths. Screenshot of the interactive Shiny app displaying COVID-19 cases, deaths, and smoke PM2.5 for each county in California and each month of 2020. Link: https://mchal053.shinyapps.io/smoke-covid/. Conclusion 2020 was a particularly strong year for wildfires in California and a unique year for infectious diseases with the COVID-19 pandemic. Our findings, using a spatially adjusted autoregressive model which controlled for important confounding variables, demonstrated that wildfire smoke exposure likely increased COVID-19 acquisition potentially via epithelial injury. This may have implications for the transmission risk for other upper respiratory tract infections. Table 1 Adjusted spatial lag model for the COVID-19 case and death incidence per 10,000 persons per 10 µg/m3 increase in PM2.5 smoke exposure in 2020. The model is adjusted for median income, outdoor laborer rate, average 2020 temperature per county, monthly 2020 precipitation per county, average elevation, month of the year, and rate of respondents reporting “Always” wearing a mask when in public within 6-feet of other another person. We found very strong evidence for a 1-month lag increase of 175 COIVD-19 cases/10,000 persons and 1.86 deaths/10,000 persons and a 2-month lag increase of 65.9 COVID-19 cases/10,000 persons. There was no 2-month lag increase in COVID-19 mortality. Disclosures Andrej Spec, MD, MSCI, F2G: Grant/Research Support George R.

The post-war fact reconstruction of the country's economic sector requires an effective format for rapid growth; it is relevant to focus on the international organizations achievements in terms, norms and standards aimed at promoting fair labor practices, enhancing safety, and encouraging sustainable agricultural practices. The aim of this article is to summarize the existing international standards, policies, principles, and requirements for the needs of employers in the economy agricultural sector. To achieve this goal, it is necessary to perform the following tasks: analyze international standards and ISO regulations, principles and recommendations of GLOBALG.A.P., evaluate FAO and ILO policies and recommendations, and explore the directions of socially responsible business in the agro-sector. The standards of the International Organization for Standardization (ISO) play a key role in agricultural economy sector business regulating and are designed to ensure food safety, environmental management, and social responsibility. They are closely interconnected and interdependent with GLOBALG.A.P. and working conditions Certification. These standards affect various aspects of activity and management in the agricultural business. Adhering to these standards is critical for enhancing business competitiveness both at the national and global levels. Implementing these components into the activities of enterprises in the agricultural sector contributes to their successful functioning and development in modern conditions.

The crisis of young farmers in the agricultural sector and the dominance of old farmers has consequences for the development of the sustainable agricultural sector, especially on agricultural productivity, market competitiveness, rural economic capacity, and further it will threaten food security and the sustainability of the agricultural sector, one of the government’s efforts to overcome this problem, the Ministry of Agriculture in collaboration with the International Fund for Agricultural Development (IFAD) implements the Youth Entrepreneurship and Employment Development Program in the Agriculture sector through the Youth Entrepreneurship and Employment Support Services (YESS) program. This program is a pilot for the regeneration of farmers in rural areas through the provision of facilities and guidance to the younger generation (men and women) to become entrepreneurs or professional workers in the agricultural sector. One of the activities of the YESS Program is competitive fund grants in the form of business capital assistance to agricultural business actors. Banjar Regency is the district with YESS participants as well as the largest number of participants receiving competitive grants in 2021. This study aims to analyze the impact of the YESS program on agricultural business activities in Banjar Regency and analyze the absorption of labor in the agricultural sector that participates in the YESS program in Banjar Regency. The research uses primary and secondary data. Primary data was taken from interviews with the help of questionnaires to participants in Banjar Regency who received competitive grants in 2021 as many as 29 people. Secondary data was taken from SMK PP Negeri Banjarbaru and other related Agencies/Agencies. The analysis used in this study is by testing wilcoxon on indicators of production costs, revenues and profits, and descriptive analysis methods on indicators of business scale, business diversification and labor absorption in the agricultural sector. The results of the study show that the YESS Program has an impact on increasing the number of agricultural businesses in Banjar Regency on the parameters of production costs, revenues, profits, business scale, and business and labor diversification that were able to be absorbed by 29 participants of the YESS Program after receiving the benefits of competitive grants in Banjar Regency of 5,697.69 HOK.

Indonesia has the potential for extensive dry land (LK). These FIs are generally in critical status and are located in disadvantaged villages, most of which are managed by poor farmers who are unable to carry out conservation efforts, so that their conditions deteriorate. The pattern of agricultural development in accordance with the characteristics of FIs is integrated farming. Integrated farming has three main functions, namely improving welfare and encouraging economic growth, food security and maintaining environmental sustainability. The well-being of the farm family is the output of the resource management process and overcoming the problems faced by the farmer family. The study aims to determine the welfare of farmers who are UTPPT actors. Research method: survey of 250 farmers in Tasikmalaya Regency in a proportional random sampling manner. Data were analyzed by analysis of income structure and expenditure structure / consumption of farmer RT food, as well as the exchange rate of rural household income (NTPRP). The results of the study: the income of farmer households comes from the agricultural and non-agricultural sectors as well as from the income of family members. Revenues from the agricultural sector are obtained from polyculture farming (forestry, plantation, horticulture and food) and livestock business. The contribution of livestock business income is greater (37.99%) than polyculture farming (35.52%) and non-agricultural (26.49%) and family member income (7.91%). Income from UTPPT is the biggest contributor to farmer household income. A total of 71.46% of farmer families share the income from the agricultural sector> 80%. As many as 63.67% of farmers depend entirely on the agricultural sector. The share of food expenditure for farmer households is still quite high, 42.19% of farmer households spend between 60-80% and> 80% on food. NTPRP has a value of> 1, farmers experience a surplus which includes the category of prosperity.

Effect of environmental pollutants PM-2.5, carbon monoxide, and ozone on the incidence and mortality of SARS-COV-2 infection in ten wildfire affected counties in California

We report the results of a 3-year study in which we collected and analyzed soil and yield data from experimental plots in six commercial processing tomato fields in Yolo and Solano counties in California. Our objective was to assess the effect of soil chemistry and soil-delivered nutrients and fungicides on tomato plant health and fruit yield at harvest. Marketable yield, leaf necrosis, and fruit loss due to sunburn differed significantly between individual fields, with averages ranging from 81.2–138.5 Mg ha−1, 32–72% leaf necrosis and 1.9 to 8.8% sunburnt fruit, respectively. Higher-yielding fields showed significantly lower levels of leaf necrosis and sunburn damage and a positive correlation with pre-plant soil parameters such as potassium concentration and cation exchange capacity (CEC). Interestingly, soil amendments of composted poultry manure or other nutrient supplements in low-CEC fields, but not high-CEC fields, resulted in higher fruit yield and less leaf necrosis. While all fields showed symptoms typical of Verticillium wilt and some fields showed symptoms of Fusarium wilt, Fusarium crown and root rot, corky root, and root knot nematode, none of our soil amendments, including chemical and biological fungicides, significantly or consistently reduced incidence or severity of these diseases. We discuss our findings in the context of premature vine decline of tomato, an emerging phenomenon in production fields in the Sacramento Valley, which is characterized by the loss of plant vigor and canopy cover at the onset of fruit ripening and for which causative agent(s) and management options in California remain elusive.

The agricultural sector is not only for the discourse of food sovereignty, but one of the foundations of the economic strategy. The erosion of agriculture by the opportunities of other sectors, refers to the focus of research in Bali's Celuk Buruan Village, by uncovering phenomena that occur in this region. The existence of regional development, the availability of access and public facilities, is a problem in the agricultural sector in this region. Changes in perspective or land-use change are inevitable, impacting agriculture and small businesses that have long worked with farmers to drive the village economy. Based on the phenomenon, an idea arose to revive the agricultural and industrial sectors in Celuk Buruan. During the Covid-19 pandemic crisis, the decline of Bali's tourism, with a qualitative approach, attempted to design, which could provide positive input to the situation. The design of media about agriculture is a preventive action, carried out in a structured, processed in the design of visual communication. In the end, communication media can produce to answer the problem and widely disseminated on the internet media.

This article aims to analyze the advantages and competitiveness of agricultural sectors and sub-sectors that have advantages in the economy of Central Java Province. The analytical tools used to determine the leading sectors and sub-sectors are location quotient (LQ), Klassen Analysis, Shift Share Analysis, and Sectoral Typology. By using data from 2023, it was found that overall, most of the sub-fields in the agriculture, forestry and fisheries business sector of Central Java Province were categorized as competitive sectors. The subsector that is not categorized as competitive is food crops. The agriculture, forestry and fisheries sector is categorized as an advanced business field and its growth is very fast, but the forestry and logging, fisheries sub-sector has a slow growth speed but is a growing industry. The agriculture, livestock, hunting, and agricultural services sub-fields have very fast and advanced growth so that they can become regional superior potential. The commodities of food crops and plantation crops still need further attention because the speed of growth is still hampered, although the industry has potential and is developing.

This study examines the effect of land area and income sources of agricultural households on their income in the context of reducing poverty in the agricultural sector. This study uses a quantitative approach and multiple regression methods as an analytical tool with data from the Agricultural Business Household Income Survey which is part of the 2013 Agricultural Census of West Sumatra Province. The data used in this study is cross-sectional data with total agricultural household income as the dependent variable and the amount of land owned by agricultural households, the area of ​​land controlled and cultivated by agricultural households, the percentage of agricultural household income from agricultural sector businesses, the percentage of agricultural household income from non-agricultural businesses, the percentage of other agricultural household income , the percentage of agricultural household income from wages in the agricultural sector, and the percentage of agricultural household income non-agricultural wage income. The results showed that the variable area of ​​land owned and the area of ​​land controlled and cultivated by agricultural households had a positive effect on their total income. Other variables that have a positive effect on total agricultural household income are the percentage of income from non-agricultural businesses and the percentage of non-agricultural wage income. On the other hand, the percentage of agricultural household income from agricultural sector businesses and the percentage of agricultural household income from wages in the agricultural sector have a negative effect on their total income. The results of this study suggest the need for redistribution of land to land-poor agricultural households and encourage them to diversify their business outside the agricultural sector but still based on agricultural products.

Climate variability is one of the important challenges in the agricultural sector. Often the occurrence of climate anomalies is a limiting factor for agricultural activities. Precise climate predictions are very useful in developing strategies for planning activities and businesses in agriculture. The Impact of Climate Change on the Agricultural and Food Sector from the danger of drought is 241,682 Ha of land and 16,835 Ha of rice fields affected by drought with Potential Losses due to climate change in 2020-2024 of 11.18 trillion rupiah—food Availability Aspect, food security index. The food availability aspect has decreased from 88.88 in 2022 & 2023 to 87.69. This writing aims to find problems in climate change mitigation and adaptation policies and compile policy recommendations for food security in Central Java. The method used is SOAR Analysis (Strengths, Opportunity, Aspiration, and Result). Based on the SOAR Analysis, the variable of increasing the capacity of human resources of farmers and agricultural extension officers who are skilled and knowledgeable about climate data and information in high-value climate-adaptive agricultural practices was obtained. Policy options that the Central Java provincial government can consider are: (1) Increasing the budget for programs such as Climate Field Schools (SLI), Climate Smart Agriculture (CSA), and the Climate Village Program (PROKLIM), (2) Expanding the reach of farmer education and training programs to all districts/cities in Central Java, (3) Improving the quality of training materials with a focus on climate-adaptive agricultural practices, use of technology, and risk management (4) Developing assistance and mentoring programs for young farmers, (5) There needs to be regulations related to increasing the capacity of agricultural human resources at the provincial and district/city levels to collaboration on program funding to have budget efficiency and increase agricultural productivity.

Serosurvey of Babesia canis, Babesia gibsoni and Ehrlichia canis in pound dogs in California, USA

Laboratory and field experiments were conducted to study the dispersal of Botryosphaeria dothidea conidia using single-drop impactions and natural and simulated precipitations. For laboratory studies, 200 single drops were released from a height of 1 m on infected pistachio nuts. On pieces of photographic film, 50% of the droplets were collected within 20 mm (average droplet travel distance) of the target area, and the droplets ranged from 0.041 to 3.19 mm in diameter, with an average of 0.3 mm. Each droplet carried an average of 23 B. dothidea conidia. In 3 years of field experiments, rainwater was collected in funnels connected to bottles positioned at different heights inside the tree canopy and at different distances away from the edge of tree canopy in three commercial pistachio orchards in San Joaquin, Yolo, and Glenn counties in California. Numbers of conidia in rainwater varied among and within sampling seasons by sampling dates and orchards. Up to 67,000 conidia/ml were obtained in rainwater samples collected from an orchard in Yolo County. Rainwater from orchards in Yolo and Glenn counties contained a consistently higher number of conidia than rainwater collected from the orchard in San Joaquin County. Variation in numbers of conidia also existed among heights where bottles were located. There were significantly more conidia in rainwater collected inside than outside tree canopies. Inside tree canopies, bottles located at 100 and 150 cm above ground collected more B. dothidea conidia than those placed at 50 and 200 cm. Conidia were collected as far as 1 m from the tree canopy edge. Based on data from the Glenn County orchard, a linear relationship between number of conidia (Y) and rainfall amount (X) in millimeters was determined as Y = 240X - 3,867, with r(2) = 0.91, which meant that a minimum of 16.1 mm of rain was needed to disperse conidia of B. dothidea. The power law model best described the dispersal gradients of B. dothidea propagules in the 1999-2000 and 2001-02 sampling seasons, with r(2) values of >/=0.73, whereas the exponential law model fit best for the 2000-01 data, with r(2) values of >/=0.81. In a rain simulation experiment, the intensity of the rain generated by a nozzle at 138 kPa of pressure inside the tree canopy was approximately five times higher than rain recorded outside the tree canopy. Rain removed up to 65% of conidia from infected fruit. These results confirmed that B. dothidea is a splash-dispersed pathogen with relatively short distances of spore dispersal within pistachio orchards. Only pycnidia are present in pistachio orchards; therefore, the results also indicate that inoculum of B. dothidea should be entirely splashed dispersed.

Clear Lake (Lake County, CA, USA) is hypereutrophic and used for drinking water, tribal use, and supports a significant fishing economy. The Mendocino Complex (2018), one of the largest wildfires in California's post‐settlement history, burned 40% of the Clear Lake watershed, providing a timely opportunity to study the impacts of historical and current wildfires on this valuable aquatic resource. Using long‐term monthly monitoring data from 1968 to 2019, paired with historical watershed fire data, we found that for the three largest fire years in the watershed's history, 3‐year postfire median July–October epilimnetic total phosphorus (TP) concentrations were below or equal to 3‐year prefire TP concentrations. However, both median TP epilimnetic concentrations and deepwater temperature across the lake have increased since the late 1960s. Long‐term TP increases were more strongly correlated with monthly maximum air temperatures than precipitation, suggesting a potential role of warming‐induced water column stratification, dissolved oxygen (DO) depletion, and high potential for internal phosphorus loading. Hypoxic occurrences were correlated with higher hypolimnetic soluble reactive phosphorus and TP concentrations, but additional high‐frequency monitoring of DO will help determine the duration of anoxia and its contribution to internal phosphorus loading. These long‐term data suggest that for this large, hypereutrophic lake, wildfires did not significantly alter in‐lake TP concentrations based on long‐term, monthly monitoring and that other internal or external sources of TP may mask any wildfire effects. Nonetheless, our study underscores the value of synthesizing decades of water quality, watershed wildfire, and climate data to build a more comprehensive, nuanced picture of multiple long‐term threats to aquatic ecosystems under global change. Moreover, monitoring and studying fire effects across a wide range of lake types beyond this study will help promote more effective lake management during changing climates and increasingly frequent large wildfires.

The internet constitutes an effective business resource as it provides a persistent communication infrastructure as well as huge business opportunities and information capital worldwide. The aim of this paper is to create a typology for e-business activities in the agricultural sector. The methodology concerns the study of the principles of e-business and its practice in the agricultural sector, the examination of the existing e-business models on the internet and, furthermore, the study of the websites promoting e-business in agriculture, their classification under the existing models and their evaluation through a multicriteria method. As a case study to apply the methodology described, the agricultural business sector in Greece is selected. Regarding classification, enterprises in the e-agricultural sector are classified according to the stage of the 'interaction', where beyond mere presence on the internet, there is a possibility for the user to navigate through the website and collect numerous information.
