Experiences And Coping Strategies During The Covid-19 Pandemic Among Fishers And Farmers In The Island Province Of Guimaras, Philippines, Gay Margarett A. Gange, Louie Marie T. Eluriaga, Alice Joan G. Ferrer

Journal of Economics, Management and Agricultural Development

This study describes the experiences and coping strategies related with the COVID-19 threat and the community quarantine policy by the fishers and farmers in the island province of Guimaras. Both food producers faced marketrelated problems such as low demand, low prices of catch and produce, and logistical problems. While the in-kind support (e.g., food provisions) received and adaptive measures (e.g., continued with fishing or adjusted harvest schedule; use of social media or delivery services in marketing) allowed them to get by during the pandemic, there is a need to develop more resilient farming and fishing households. Short-term support can be …

Archipelago On Lockdown: An Assessment Of The Effects Of The Covid-19 Pandemic On Philippines’ Micro, Small, And Medium Enterprises (Msmes) Across The Food Value Chain, Remund Jordan D. Labios, Dinah Pura T. Depositario, Nohreen Ethel P. Manipol, Renen Szillardo C. De Guzman, Dia Noelle F. Velasco

Journal of Economics, Management and Agricultural Development

The paper examined the effects of COVID-19 pandemic on the Philippines’ MSMEs across the food value chain and the strategies that food-based MSMEs employed to cope with disruptions. A food value chain framework was used to
analyze the food-based MSMEs, focusing on the input and service provision, production/farming, processing, transport and storage, retailing, and consumption. Results revealed the following: (1) different quarantine protocols across provincial and local boundaries contributed to the complexity of transporting inputs and products; (2) limited mobility of manpower contributed to the challenges of continuing business operations; (3) there was an observed increase in new financing programs …

An Assessment Of Swine Industry In The Philippines, Christian Paul L. Fang, Cenon D. Elca

Journal of Economics, Management and Agricultural Development

This paper assessed the performance of swine industry in the Philippines by synthesizing secondary data from 1990 to 2020. Inefficiencies in major swine value chain segments were identified. The factors affecting swine production and pork consumption were determined using multiple regression analysis. The bottlenecks found along the chain are yellow corn supply deficit, fragmented structures of yellow corn and backyard farms, high disease susceptibility of backyard farms, and compromised meat quality produced from private slaughterhouses. The own price, inventory, and slaughtered animals have significant direct effects on swine production. The retail price of pork and income have significant direct influences …

Towards Consumer-Oriented Mushroom-Based Product Development: An Exploratory Study In Rice-Based Farming Communities In Central Luzon, Philippines, Josefina F. Ballesteros, Rosaly V. Manaois, Amelia V. Morales, Riza Abilgos-Ramos

Journal of Economics, Management and Agricultural Development

This study determined consumers’ awareness and interest towards mushroom and mushroom-based product ideas. A survey of 222 adults was conducted in rice-based farming communities in selected provinces, namely, Aurora,
Bulacan, Nueva Ecija, and Pampanga. Results showed that taste, nutritional, and health benefits were the top attributes considered by both sexes whenever they buy food for household consumption. Most of the respondents (99%) liked eating mushroom because of its palatability (71%) and perceived healthiness (26%). However, the majority (76%) consumed mushrooms only once a month or seldom in a year due to its limited availability. Food supplements, coffee-like beverages, and snacks …

This study aimed to explore the impact of the farmgate price of hogs, the volume of hog production, the volume of imported pork, the market retail price per kilo of dressed chicken, the quantity of pork consumed by the population, the GDP per capita, and African Swine Fever (ASF) on the pork market retail price in the Philippines. The Autoregressive Distributed Lag (ARDL) approach was implemented to model the pork price using quarterly data from 2000 to 2020. The long-run model showed that farmgate price, hog production, and imported pork during the presence of ASF could affect pork price. Moreover, …

Investigating The Intention To Work Overseas Among Filipino Engineering Students By Testing A Structural Equation Model Based On An Extended Theory Of Planned Behavior, John Lester Remot, Maria Liezel P. Caroche, Alan Marco S. Mercado, Marc Joseph S. Villanueva

Journal of Economics, Management and Agricultural Development

This study examined the antecedents of Filipino engineering students’ intention to work overseas, applying the theory of planned behavior (TPB) (involving attitude, subjective norm, and perceived behavioral control) extended with migration push and pull factors (PPF) (involving salary and compensation, career prospects, and quality of life). Structural equation modeling using 1,706 questionnaire responses proved that the PPF dimensions were indistinguishable, while another factor distinct from attitude, evoking the perceived enjoyment of working overseas (PEJ), emerged. The TPB and PPF were identified as important antecedents of intention (R2 = 0.667). PEJ had no direct effect on it but was significant along …

Storm Surges In The Bohai Sea: The Role Of Waves And Tides, Yuanyi Li, Huan Feng, Guillaume Vigouroux, Dekui Yuan, Guangyu Zhang, Xiaodi Ma, Kun Lei

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

A storm surge is a complex phenomenon in which waves, tide and current interact. Even though wind is the predominant force driving the surge, waves and tidal phase are also important factors that influence the mass and momentum transport during the surge. Devastating storm surges often occur in the Bohai Sea, a semi-enclosed shallow sea in North China, due to extreme storms. However, the effects of waves on storm surges in the Bohai Sea have not been quantified and the mechanisms responsible for the higher surges that affect part of the Bohai Sea have not been thoroughly studied. In this …

An Exploratory Study On The Managerial Competencies Of First-Line Managers In A Philippine University, Alyssa Kaye S. Mojar, Dinah Pura T. Depositario

Journal of Economics, Management and Agricultural Development

Faculty and researchers, mostly well-trained, usually fill managerial positions at universities. Still, they do not have formal management training. This qualitative study examined the managerial competencies of 11 university firstline managers. Using Kurz and Bartram’s Great Eight Competency Theory (2002) for the thematic analysis of the interview transcripts, most of the respondents exhibited all eight competencies. However, they differed in terms of manifestations. A typology of academic administrators was developed based on the eight competencies, namely: (1) delegator, (2) accommodator, (3) director, and (4) initiator. Further quantitative research is recommended to refine this typology. Likewise, to develop current and potential …

Intercropping For Water Conservation: Environmental And Economic Implications Of A Sustainable Farming Practice In California's Central Valley, Sophie Baker

Scripps Senior Theses

California’s agricultural sector is the biggest water consumer in the state and faces intense pressure to reduce its overall water usage. Industrialized monoculture systems dominate the industry and often disregard long-term environmental and economic externalities for short-term profit maximization. To maintain longstanding food security and economic stability as well as protect the state’s water supply, it is critical that these systems transition to more sustainable and resilient production mechanisms. As an alternative to monoculture, intercropping affords greater potential to conserve water, protect soil quality, and increase crop yields, among other metrics of sustainability. However, there has been much controversy over …

Green Strategic Planning Approach For International Shipping Activities, Xiaofang Wu, Luoping Zhang, Huan Feng

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Sustainability is a long-term and ultimate goal for international shipping, although it is slowly making progress. The shipping perspective that moves away from “port-to-port” operations to “door-to-door” services also requires international shipping to take a long-term and holistic view instead of fragmented efforts. How to achieve the long-term sustainability goal becomes a key issue for door-to-door international shipping. Hence, green strategic planning for door-to-door international shipping was proposed with green development that puts forward the eco-centric point of view as its basic theory for sustainability. This study used a strategic decision-making approach, a so-called multi-dimensional decision-making (MDDM), coupled with the …

Under Field Conditions, Marek Kolenčík, Dávid Ernst, Matej Komár, Martin Šebesta, Martin Urík, Edmund Dobročka, Ivan Černý, Ramakanth Illa, Raghavendra Kanike, Qian Yu, Huan Feng, Denisa Orlová, Gabriela Kratošová

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

It has been shown that the foliar application of inorganic nano-materials on cereal plants during their growth cycle enhances the rate of plant productivity by providing a micro-nutrient source. We therefore studied the effects of foliarly applied ZnO nanoparticles (ZnO NPs) on Setaria italica L. foxtail millet’s quantitative, nutritional, and physiological parameters. Scanning electron microscopy showed that the ZnO NPs have an average particle size under 20 nm and dominant spherically shaped morphology. Energy dispersive X-ray spectrometry then confirmed ZnO NP homogeneity, and X-ray diffraction verified their high crystalline and wurtzite-structure symmetry. Although plant height, thousand grain weight, and grain …

Producer Preferences For Alternative Irrigation Practices In The Arkansas Delta, Robert Edward Rosene

Graduate Theses and Dissertations

We use a bivariate sample selection model to address peer network effects on participation in and/or intensity of use of land being irrigated by alternative irrigation practices in the state of Arkansas. As groundwater in the state becomes more limited, the use of scientific scheduling, flowmeters, and more efficient row crop water application systems will allow producers to better manage water resources. We find relatively large, positive relationships between belonging to a peer network of the same irrigation practice and participation in that practice. Intensity of use of alternative irrigation techniques is mostly influenced by which crop type the practice …

Farm To Label: A Critique Of Consumer Activism In The Sustainable Food Movement, Olivia Whitener

Pomona Senior Theses

“Local,” “organic,” “natural,” and “Fairtrade” are just several of the many claims adorning the food products that line grocery store shelves. These promises of environmental sustainability and social responsibility are pillars of the “good food revolution” sweeping the nation as consumers demand alternatives to the products of the industrial food system. Green consumerism, the premise that consumer demand for environmentally sustainable goods will bring about ecologically beneficial outcomes, is at the heart of the sustainable food movement. This thesis takes a critical look at the operation of green consumerism in the food system. It explores the ideology and shortcomings of …

A hopeful vision of the future is a world in which both people and nature thrive, but there is little evidence to support the feasibility of such a vision. We used a global, spatially explicit, systems modeling approach to explore the possibility of meeting the demands of increased populations and economic growth in 2050 while simultaneously advancing multiple conservation goals. Our results demonstrate that if, instead of “business as usual” practices, the world changes how and where food and energy are produced, this could help to meet projected increases in food (54%) and energy (56%) demand while achieving habitat protection …

The Growing Sustainable Seaweed Industry: A Comparison Of Australian State Governance Directing Current And Future Seaweed Cultivation, Meagan E. Currie

Independent Study Project (ISP) Collection

Seaweed is a critical part of natural marine ecosystems. In addition to supporting the marine environment, seaweeds are a significant global resource with nutritional, industrial and pharmaceutical applications. Seaweed also has the capacity to remediate excess nutrients in the water caused by agricultural or aquacultural waste of other organisms. Seaweed has demonstrated large potential as a remediation tool in land based polyculture and offshore Integrated Multi Trophic Aquaculture (IMTA) systems.

Seaweed is already worth over US$7 billion as a global industry, but as of 2013 over 93% of global seaweed is produced in Asia (Lorbeer, 2013, p. 718). Australia imports …

Invasive-Plant-Removal Frequency—Its Impact On Species Spread And Implications For Further Integration Of Forest-Management Practices, Bernabas Wolde, Pankaj Lal

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

For a given invasive plant species and control method, effective invasive plant eradication requires regular monitoring and management. While most previous studies characterize invasive plant species, develop appropriate control methods, or prioritize species for management using aggressiveness and other considerations, few study why some forestland owners are less likely than others to regularly remove invasive plant species. Such information is useful in prioritizing and targeting forestland owners who are at greater risk for invasion, with the stands threatening adjacent forestlands. Towards this end, we surveyed 1800 forestland owners in Virginia and Texas. We use data on forestland owners’ socioeconomics and …

The Effect Of Two Different Harvesting Methods On The Yield Of 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) When Grown In A Wiregrass Tunnel House, Veronica E. Walton, Raymon Shange, Melissa Johnson, Edward Sparks, Victor Khan, James E. Currington, Ramble Ankumah, Nathaniel Ellison, George X. Hunter Jr., Jeffery L. Moore

Professional Agricultural Workers Journal

A study was conducted to determine if 100% or 50% harvesting of collard leaves was a suitable recommendation for Tunnel House producers. The experiment was conducted as a split-split plot design with varieties as the main plots, harvesting 100% or 50% of leaves as the sub-plots, and days after transplanting as the subplots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between varieties and method of harvest, for leaf numbers and weight. Conversely, the varieties showed significant differences for yield but not leaf numbers. Both varieties showed significant …

Toxic Effects Of Lead Disposal In Water: An Analysis Of Tri Facility Releases, Patrick Koval

Economics Department Working Papers

Using county-level TRI data from 2003 to 2016, I find evidence that lead emissions in water adversely affect birth weights within the emitting county, especially with respect to the percentage of births considered low birth weight within that county (less than 2,500 grams). I find that a one percent increase in lead emissions per square mile increases the proportion of low birth weights by 0.27 percentage points. For a county with an average number of births in a particular year, this one percent increase in lead per square mile translates to an additional $475,000 in hospitalization costs from complications with …

Irrigation Management, Environment, And Profits: Who Wins?, Emily O'Donnell

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The impact of irrigation technology on farmers’ management strategies and resulting environmental benefits depends upon agronomic properties and market forces. We evaluate the role of deficit irrigation using soil moisture probe technology on corn yield and evapotranspiration, which is a measure of water use efficiency. Evapotranspiration represents the water that transits through the plant during planting to harvest (transpiration) and the evaporation from the soil into the environment, or the displaced water in the production process. We develop yield and evapotranspiration response functions to inform a constrained profit maximization model used to identify the optimal irrigation level across a variety …
