Abstract

Increasing food demand and climate change-induced natural disasters pose significant challenges to food security. This study examines how forest conservation can mitigate disaster risks to agricultural land in Northern Thailand’s watershed. The Soil and Water Assessment Tool (SWAT) and Hydrologic Engineering Center’s-River Analysis System (HEC-RAS) models were used to assess flood impacts, while the standardized precipitation and evapotranspiration index (SPEI), vegetation health index (VHI), and standardized streamflow index (SSI) evaluated drought impacts, incorporating two Coupled Model Intercomparison Project Phase 5 (CMIP5) climate projections and five land-use scenarios. Historical data shows drought causing more yield loss than floods for rice and maize, a trend expected to continue. Under future Representative Concentration Pathways (RCP) 8.5, potential rice yield loss due to drought could reach 1,834 tons and maize yield loss 7,702 tons. Flood-induced losses are lower, with potential rice yield loss at 26.2 tons and maize at 16.9 tons. Reforestation can reduce these losses by up to 25% for drought and 20% for floods. Maintaining forests in mountainous and upstream watershed areas is essential to ensure food security. Policymakers should prioritize conserving these critical areas for effective water regulation and disaster risk reduction. Forests in these areas play a crucial role in regulating water flow, reducing runoff, and enhancing soil moisture retention, which is vital for mitigating the impacts of extreme weather events on agriculture. Keywords: climate change, drought impact, ecosystem-based disaster risk reduction, flood impact, food security

Abstract

This research analyzes the influence of road length, rail length, containers traffic, air freight, GFCF, and labor force on economic growth. This study uses quantitative methods with G7 countries as research objects during 2010-2021. Panel data consisting of 84 observations was analyzed with the help of Eviews12 software. The statistical analysis used in this research is the Ordinary Least Square (OLS) method, with the Fixed Effect Model chosen as the best model for interpreting the research results. The findings show that the road length, container traffic, air freight, GFCF, and the labor force have a positive and significant influence. Meanwhile, only the rail length does not have a significant effect on economic growth. Based on the results of this research, the theoretical implication of this research is the development of transportation infrastructure, especially road length, containers, air freight, GFCF, and labor force can increase economic growth in a country. So countries must consider spending on developing transportation infrastructure. Meanwhile, practically, this research can be used as study material in considering infrastructure development because the negative impact caused by errors in infrastructure development can be a waste of budget.
