This study adopts the following methodology to comprehensively analyze drought vulnerability and derive effective countermeasures:
Collection and Analysis of Foundational Data:
Collecting meteorological data (precipitation, temperature, soil moisture) and agricultural data (crop yields, irrigation practices) from government and open-access databases.
Data Utilization Example: Big data analysis is used to analyze regional water consumption patterns and optimize the water supply system, which helps to reduce water loss and enhance efficiency. (Source: K-water's Smart Water Management Innovation Cases)
Review of Policies and Case Studies:
Reviewing and analyzing existing drought adaptation policies and community-level mitigation measures through literature and case studies.
Evaluation of Vulnerability Factors:
Evaluating the environmental, socio-economic, demographic, institutional, governance, and technological conditions that affect vulnerability to drought from multiple perspectives.
The effective drought mitigation and adaptation methods identified through the research are presented below, supported by quantitative results focusing on water management and data utilization.
Smart Water Systems: Installing smart water meters and sensors allows for real-time monitoring of water consumption.
Quantitative Data: The global Smart Water Management Market is projected to grow from $13.79 billion in 2022 to reach an expected high with a Compound Annual Growth Rate (CAGR) of 11.3% through 2030. (Source: INFINITIVE DATA EXPERT, 2022)
Climate-Smart Agriculture (CSA): Applying a suite of integrated practices that help farms adapt to climate change and enhance resilience.
Case Study Data: Results from Vietnam's '1M5R' CSA program showed a 10–18% increase in rice yield, a 28.6% increase in farmer income, and a 15–40% reduction in water usage. (Source: Asia Review, 2025)
Efficient Irrigation (Drip Irrigation): Adopting highly efficient irrigation systems, including switching to Drip Irrigation, which delivers water directly to the plant's root, minimizing evaporation.
Efficiency Data: The Rural Development Administration's ICT-based sub-surface drip irrigation technology showed that agricultural water was 22% conserved compared to conventional methods for field crops, while soybean yields increased by 26% compared to non-irrigated plots.

Use of Climate Model Data: Utilizing up-to-date climate model data for long-term drought forecasting and planning.
GIS and Remote Sensing Technologies: Using GIS and remote sensing to map drought vulnerability across spatial units and enable real-time monitoring.
Technological Advantage: Remote sensing (satellite imagery) allows for the analysis of plant health indicators, such as chlorophyll levels, over large areas, enabling the early detection of plant stress due to drought before visible damage occurs. (Source: FlyPix AI)
