Diesel to Solar Irrigation System: Economic, Environmental, and Social Acceptability Analyses by Small-Scale Farmers of Calapan, Oriental Mindoro
2024
Charmaine Samala Guno
Solar irrigation systems are sustainable practices that can improve the well-being of local communities and enhance the resilience of agriculture to climate change while reducing environmental impacts. Due to its high investment cost, small-scale farmers are inclined to use traditional fossil-based irrigation systems that can harm humans and the environment. This study aims to analyze the environmental impacts, economic feasibility, and social acceptability of shifting agricultural practices from diesel-fueled to solar irrigation systems. Taking the perspective of small-scale farmers from Calapan City, Oriental Mindoro, results found that solar irrigation system has a higher initial investment but lower maintenance and operational costs. These resulted in an attractive economic feasibility of the project with Php 19,693 of fuel cost savings per hectare per year, a project net present value of Php 10,214 per hectare, a payback period of 8.27 years, and returns on investment at 110%. Additionally, shifting to a solar irrigation system significantly reduces the greenhouse gas emissions from diesel at 199.78 CO2 eq/ha/yr, and avoids air pollutant emissions at 14.91 g/ha/yr particulate matter, 2.98 g/ha/yr nitrogen oxides,193.82 g/ha/yr sulfur oxides, and 149.09 g/ha/yr carbon monoxide. Despite the lack of in-depth environmental awareness, small-scale farmers are interested in investing in solar irrigation systems with 68% social acceptability. Results provide bases for recommendations on promoting more human ecologically and sustainable agriculture irrigation systems in the Philippines and other developing countries.

2024
Christine Andrea R. Arias | Recylyn I. Bayna-Mariano
Lockdown measures brought about by the COVID-19 pandemic have notably shifted food purchasing behavior towards online food delivery services (OFDS). This study examined consumer satisfaction with OFDS and their relationship to food choice and frequency of use among 18-24-year-old University of the Philippines Los Baños (UPLB) students. Through a survey of 80 students who used OFDS during the pandemic, our results revealed that while price significantly influences food choice, the quality of online service (E-service quality or ESQ) results in customer satisfaction. Notably, our analysis showed a strong, positive relationship between food choice factors (i.e., mood, convenience, sensory appeal, natural content, and price) and consumer satisfaction factors (i.e., time-saving orientation (TSO), hedonic motivation (HM), price-saving orientation (PSO), convenience motivation (CM), food quality (FQ), and ESQ), which, in turn, correlated with increased usage frequency. These findings highlight the importance of a comprehensive approach in online food service offerings to enhance well-being by addressing the key factors influencing consumers’ food choices and satisfaction. Our study suggests that improving factors such as hedonic motivation could encourage frequent use of OFDS, underscoring the need for targeted strategies to cater to young adult preferences in the changing dynamics of food delivery services.

The definition of the new normal stretches towards the notions of pandemic-ready and climate-resilient communities. The recent COVID-19 pandemic and the intensification of climate-related hazards have challenged the disaster management and preparedness of those in developing countries. Baybay, among other cities in the Philippines, had endured the devastation of typhoons and landslides in the middle of the pandemic. While the city grappled with its responses to address the dual threats of the new normal, its implementation of the Barangay Integrated Development Approach for Nutrition Improvement (BIDANI) strategy in 2010 through the Visayas State University (VSU) equipped the local government unit (LGU) with sectoral data and database management for evidence-based decision-making, digital information systems, and nutrition-related interventions in the barangay level. Using the narratives of the LGU and VSU-BIDANI teams, this paper intends to present a comprehensive overview of the significance of BIDANI in addressing LGU governance challenges, especially in planning and development for disaster responses. This paper suggests strengthening the partnership between LGUs and academia to foster good local governance.

In the Philippines, an underutilized crop known as adlay has been found to contain valuable nutritive potential. Given Filipinos’ usual diet of snacks and ready-to-eat food items, the study aimed to provide an alternative choice for healthy snacks by utilizing adlay in developing cereal bars with an improved nutritional profile. The study developed cereal bars using varying proportions of oats and adlay grains as follows: control (100:0), treatment 1 (75:25), treatment 2 (50:50), and treatment 3 (25:75). The cereal bars were then subjected to sensory evaluation to determine their acceptability using a nine-point hedonic scale with 67 adult respondents. The control and the most acceptable treatment then underwent proximate and mineral analyses (iron and calcium). The sensory data was analyzed using Kruskal-Wallis H-Test with rank analysis, whereas the proximate and mineral content data were analyzed using the student’s t-test at p<0.05. Results showed no significant difference between the control and all the treatments regarding sensory characteristics, and treatment 1 got the highest rank among all treatments. Proximate and mineral analyses revealed that treatment 1 has significantly higher crude protein (11.25 ± 0.66%), crude fiber (10.79 ± 1.22%), crude fat (17.82 ± 1.10%), and calcium (1.08 ± 0%), than the control made of pure oats. The findings, therefore, suggest that adlay can be used as a value-added ingredient in making sensory-acceptable cereal bars with an improved nutritional profile.

Constructed wetlands are globally recognized as effective nature-based solutions to wastewater treatment providing significant ecological and socio-economic benefits. This study aims to identify the ecosystem services provided by the constructed wetlands and evaluate their economic value. This study administered a survey questionnaire to 270 households of Fishermen’s Gawad Kalinga Village in Bayawan City, Negros Oriental, Philippines and employed a contingent valuation method to investigate their willingness to pay for the constructed wetlands. Respondents identified several ecosystem services of the constructed wetlands including the provisioning (water supply and biomass), regulating (wastewater treatment, water purification, climate regulation, flood prevention), supporting (habitat formation, nutrient cycling, hydrological cycle), and cultural (tourism, educational and research, recreation, aesthetic) services. Results showed that 96.3% of the respondents were willing to pay for the ecosystem services, with a mean of PHP 107.28. In terms of socio-demographic characteristics, age group and sex have no significant impact on WTP; while positive, weak, monotonic association for highest educational attainment; and positive, very weak for monthly income. The findings hold a significant promise for the government and other stakeholders to adopt a constructed wetland in achieving more human ecological and sustainable peri-urban communities.

This study was conducted to assess the role of Butuanon River Watershed Management Board (BRWMB) in rehabilitating the Butuanon River in Cebu, Philippines. Data was gathered through key informant interviews with officials of the Board and a self-administered questionnaire for the members of the Board and was analyzed through descriptive and thematic analyses.Results showed that since the creation of the Butuanon River Watershed Water Quality Management Area (BRW WQMA) in 2014, the river’s biological oxygen demand (BOD) level has decreased. While the level has yet to meet the water quality guidelines of DENR’s Class D rivers, the Board’s initiatives like clean-up activities, information, education, and communication (IEC), and the relocation of informal settlers residing at riverbanks contributed to the improvement of the river’s water quality. The activities conducted by the Board strengthened the linkages with other stakeholders. The good working relationship among the stakeholders facilitated the convergence of their resources, making their efforts to rehabilitate the Butuanon River more coordinated and sustainable. Furthermore, Mandaue LGU, the chair of BRWMB, integrated its efforts in its Comprehensive Land Use Plan (CLUP) and the 10-year Action Plan of the BRW WQMA in its Butuanon River Rehabilitation Plan.Results revealed that the existence of BRWMB played a vital role in the Butuanon River’s rehabilitation, and such efforts are hoped to be sustained with the participation of the various stakeholders and formulation of policies to support all efforts of the Board.
