“…In agricultural land, climate change caused decreased food crop production [8]. In Indonesia, the impact of climate change has increased temperature, sea level, and rainfall intensity [9][10][11][12]. The low-lying characteristics, decrease of the water system, and the impact of extreme rainfall cause an increase in the depth and area of inundation in the Katingan rice fields [13].…”

Rice fields in the Katingan tidal lowlands are inundated due to spring tides and extreme rainfall. Excessive inundation in the rice fields causes crop failure. Therefore, the study was conducted to analyze the use of water gates in the secondary canals for controlling the inundation. The unsteady flow simulation boundary conditions are the upstream discharge with a return period of 5 and 25 years and measured tidal. The water flow is controlled by closing the sluice gates at the water level elevation of +3.50 m, and flap gates close during high tide and rainfall. This research shows that controlling the water flow by gates decreases the water level and inundation area. Under rainfall with a return period of 5 years, the inundation area decreased by 79.03 %, and the maximum water level decreased by 0.14 m. In the rainfall with a return period of 25 years, the inundation area decreased by 75.31%, and the maximum water level decreased by 0.11 m. The water gates’ operation incompletely decreases the inundation and water level beneath rice crops’ threshold inundation depth and duration. Therefore, there is a need for additional water control to optimize the decrease of inundation in the rice fields.

The Island of Catanduanes is located in the eastern most fringe of Luzon considered to be the doorstep of typhoon path. The rainfall in the province is important in producing agricultural food to make life in the province sustainable. Hence, it is necessary to establish how the effect of climate change variable on the availability of water in the island, so that impending extreme drought or flooding will be mitigated. In addition to that, Climate change in the island has an impact on human activity, and a treat from flooding of variable weather pattern like seasonal monsoon rain and inter tropical convergence zone develop near the island. Using the data from the PAGASA-DOST, Climatology and Agro meteorology Division (CAD) of April 2020, from the Virac Doppler and Radar Weather in Catanduanes. Synoptic data were used to evaluate the rainfall for the last 30 years. The rainfall pattern caused by the southwest monsoon (Habagat) most from June to September gives an average of 73.08mm for 3 decades. Northeast monsoon (Amihan) usually arrives on November and ends on March having an average rainfall of 103.78mm for 3 decades. It has been shown that the rainfall is increasing every year, the annual rainfall trends will increase of up to 10.76mm in the next 10 years. Studying the rainfall pattern and temperature will give us more precise assessment of the climatic condition in the island and give the community and the government the proper information for mitigating and planning on how we can handle climate change.

“…In Sub-Saharan Africa, climate change and variability pose a very serious challenge to the social, economic, and ecological system (Kotir, 2011). Several researchers in Africa observed that the current changes in climate conditions have resulted in changes in the rainfall patterns of different regions (Meshram et al, 2018;Sipayung et al, 2018).…”

Dar es Salaam, like other cities in Africa, experiences flash floods during the rainfall season that destroy infrastructure due to the overflow of rivers and blocked sewage. This study investigates the historical and future variability and changes in spatial and temporal rainfall over Dar es Salaam. Station data and Climate Hazards Group Infrared Precipitation with Stations (CHIRPS) gridded data crossing 38 years (1982–2019) were used as a baseline and the Coordinated Regional Climate Downscaling Experiment (CORDEX) dataset from 2021 to 2050 was used for projection under Representative Concentration Pathway (RCP 4.5) forcing scenarios. A trend analysis of historical data was conducted at monthly, seasonal, and annual timescales. Mann–Kendall statistical tests and Sen’s slope estimator were applied to identify the current trend direction and magnitude of changes in rainfall patterns over time. A standardized anomaly index (SAI) was also employed to detect the region’s trends in wetness and dryness. The spatial distribution of rainfall in the city was investigated using an inverse distance weighted (IDW) interpolation technique. The statistical results reveal that a non-significant trend in rainfall was observed on monthly, seasonal, and annual timescales. Generally, in the future (2021–2050), the annual cycle of rainfall shows a slight decrease in monthly rainfall, especially from January to August, and an increase from September to December compared to historical (1982–2019) rainfall, for most of studied locations. Spatially, the distribution of projected rainfall shows that the southern part of the city will experience higher rainfall than other parts. The most significant findings were a decrease in annual projected rainfall by 20%, the MAM projected rainfall season increased by 42%, and an increase of 38% of the OND-projected rainfall season. The findings of this study will be useful for the improved management and planning of the city.
