Application of the self-calibrated palmer drought severity index and standardized precipitation index for estimation of drought impact on maize grain yield in Pannonian part of Croatia

Kreso Pandzic et al.

Summary: The study investigated the impact of drought on maize yield and the correlation of drought indices at different time scales, revealing that drought in 2017 led to a decrease in maize yield, while 2018 was normal.

Assessment of Relationship between Climate Change, Drought, and Land Use and Land Cover Changes in a Semi-Mountainous Area of the Vietnamese Mekong Delta

Tran Van Ty et al.

Summary: Agriculture in the Global South is vulnerable to climate change, as seen in a semi-mountainous region of the Vietnamese Mekong Delta where drought and land use change have been impacted. Future projections indicate increased precipitation, temperatures, and drought events. Additionally, agricultural land has decreased while non-agricultural land has increased.

Understanding Dry and Wet Conditions in the Vietnamese Mekong Delta Using Multiple Drought Indices: A Case Study in Ca Mau Province

Huynh Vuong Thu Minh et al.

Summary: This study evaluates both dry and wet conditions in the Vietnamese Mekong Delta and investigates their impact on agricultural output. The findings highlight the prolonged drought periods in the region and the significant damage to rice and shrimp outputs. These results are important for designing more robust water resource management plans.

Evaluation of the Impact of Drought and Saline Water Intrusion on Rice Yields in the Mekong Delta, Vietnam

Huynh Vuong Thu Minh et al.

Summary: The Mekong Delta in Vietnam is a crucial region for rice production, but it faces challenges such as saline water intrusion and drought. This study examines the impacts of these challenges on rice yields over a 40-year period. The research finds that drought occurrences have increased in the winter-spring rice cropping season, and some inland regions also experience increased drought in the summer-autumn season. It emphasizes the need for evidence-based planning and investment in sustainable water infrastructure to improve system resilience.

Seasonal variation and its impacts in rice-growing regions of the Mekong Delta

Van Hong Nguyen et al.

Summary: The study aimed to establish rice planting seasons in An Giang, a province in the Mekong Delta, in response to potential risks of drought, saline intrusion, and heavy rainfall due to climate change. Using a crop model, the impacts of seasonal variation on key rice seasons were simulated, showing an increase in crop yield for the spring, summer, and autumn-winter seasons in the study area. This research highlights the importance of adjusting planting seasons based on weather factors to optimize crop production in the face of climate change.

Spatial and temporal patterns of propagation from meteorological to hydrological droughts in Brazil

Alena G. Bevacqua et al.

Summary: This study characterized meteorological and hydrological droughts in 457 basins in Brazil using standardized indices, finding that hydrological droughts are usually more severe and have a longer recovery time compared to meteorological droughts. The most severe and long-lasting droughts are typically found in the driest regions or areas mainly impacted by human activities. Different approaches may result in slightly different propagation times.

Future rice farming threatened by drought in the Lower Mekong Basin

Hyunwoo Kang et al.

Summary: The study found that rice yield in the Lower Mekong River basin may increase due to elevated atmospheric CO2 concentration and increased precipitation, but significant decreases in rice yield could be expected in the Vietnam Central High Plain region. To prevent a major food crisis, expanding irrigation areas to compensate for the expected reduction in rice yields may be necessary. A framework combining hydrology and crop models is key for assessing climate change impacts on food production and developing adaptation strategies in the future.
