Abstract

Background: Climate change poses a profound and escalating threat to global food systems, particularly for small-scale aquaculture communities such as shrimp farmers in coastal regions, whose livelihoods and food security are increasingly vulnerable to environmental variability and extreme weather events. Methods: This study investigated the impact of climate change adaptation strategies on household food security in Bangil Regency, East Java, Indonesia, based on a comprehensive analysis of 1500 shrimp farmers. Using the innovative Multivariant Probit (MVP) method to identify factors influencing the decision to adopt adaptation practices. These factors include changes in the timing of clear fry dispersion, acceleration of harvest time, polyculture practices, and changes in the type of clear fry. We also employed the Ordered Probit Model to evaluate the impact of climate change adaptation on food security, as measured by the food insecurity experience score. Results: A strong positive relationship was revealed between the level of adaptation applied and the resilience of household aquaculture among shrimp farmers. This correlation shows that the more intense adaptation is implemented, the better the food security status of households. Conclusion: This study shows that climate change adaptation has a positive impact on food security. These findings underscore the need for adaptation strategies, especially for small-scale farmers, and tailored interventions to ensure food security in the face of climate change challenges.

Abstract

Background: The increasing adoption of mobile phones among smallholder farmers in Indonesia presents new opportunities to access agrometeorological and climate change information, essential for climate adaptation in rural agricultural areas. Aim: This study examines the extent to which mobile phone ownership influences access to climate change adaptation information among smallholder farmers in East Java. Methods: A cross-sectional survey was conducted involving 7,850 smallholder households. The study assessed the relationship between mobile phone ownership and its use for accessing climate-related information, participating in farmer groups, and conducting agricultural transactions. Logistic regression was applied to identify key determinants of mobile phone utilization. Results: Of the total respondents, 54.4% reported owning a mobile phone. Among them, 46.4% used their phones to access climate change information, 41.4% engaged in buying and selling agricultural products, and 46.4% participated in farmer organizations. Mobile phone ownership and group membership were significantly associated with mobile phone use for agricultural purposes (p < 0.001). Conversely, age and household income were not statistically significant. Notable variations were also observed in relation to smartphone ownership, gender, and educational level, with higher education and female participation linked to increased utilization of phones for climate-related activities. Conclusion: Mobile phone ownership plays a critical role in enhancing access to climate adaptation information and agricultural engagement among smallholders. The findings highlight the potential of digital tools to strengthen resilience and support climate-smart practices. Promoting equitable access to mobile technology, particularly for women and less-educated farmers, is vital for inclusive agricultural adaptation strategies.

Abstract

Background: The agricultural sector faces several challenges, including low productivity, high production costs, and unsupportive policies, which hinder the sector's full potential. This article examines the roles of technology, government policy, and institutions in promoting agricultural development, based on a literature review of the book Economics of Development by Perkins et al. (2013). Aim: This study aims to elucidate the importance of agricultural sector growth and modernization. Methods: This review employs the Literature Review method, drawing upon various scholarly sources related to Agricultural Development and other relevant literature to serve as references and comparative material for the discussion. Results: The review finds that technological innovation and institutional capacity consistently emerge as the most decisive mechanisms for agricultural modernization, while policy effectiveness shows mixed evidence across different contexts. Although there is broad agreement that agricultural growth strongly contributes to poverty reduction, divergence remains regarding the extent to which trade liberalization benefits smallholder farmers. Conclusion: Therefore, an integrated policy approach, the use of appropriate technologies, and the strengthening of institutional frameworks are essential strategies to maximize the agricultural sector’s contribution to economic development and poverty alleviation.
