Summary: Rainwater harvesting systems are widely implemented in urban areas to address water scarcity and stormwater issues. However, the impacts of rainfall change on these systems vary in different climatic zones. This study found that rainfall change can affect both water saving and stormwater control performance of rainwater harvesting systems in Pakistan, with specific locations requiring adaptive measures to mitigate negative impacts.

Summary: This study develops a user-friendly simulation tool for rainwater harvesting and investigates its effectiveness through two case studies. The results show that rainwater harvesting can augment problematic or insufficient water supplies, with roof area and rainfall distribution having the greatest impact on the system's ability to meet demand.

Summary: Water resources management is crucial for rural communities in drylands, and water harvesting technologies can play a significant role in intercepting surface runoff and storing water. This study aims to fill the knowledge gap on the performance of Marab technology in different environments by simulating its hydro-agrological effects using the AquaCrop model. The simulation-based assessment reveals that Marab-based farming has a huge improvement potential for barley production, with an average yield of 8.37 t ha(-1) compared to a highly variable yield of 0.34 t ha(-1) without the technology.

Summary: It is evident that climate change will continue to affect all regions of the planet this century, with varying impacts across different areas. Measures of mitigation and adaptation are crucial in urban environments, and rainwater harvesting systems have been considered a suitable solution. However, existing studies have largely focused on buildings and there is limited research on the application of these systems in larger urban infrastructures.

Summary: This study examines rainfall variability and trends in Africa using TAMSAT data from 1983 to 2020. The findings show that certain regions have higher annual rainfall trends, while others have lower trends. There is a statistically significant increase in rainfall in countries located in the northern and central parts of Africa, while no significant change is observed in countries in the southern and eastern regions. The study also reveals a significant increase in rainfall in certain tropical climate zones. These findings are crucial for decision-makers involved in crop planning and water resource management.

Summary: The study evaluates changes in percentile-based precipitation extreme indices, showing increases in most land areas with observations during global warming. CMIP6 models replicate overall increases, but with some regions experiencing considerable over- or underestimations. Fingerprinting analysis reveals detectable anthropogenic signals globally and continentally, with greenhouse gas signals separately detectable over the globe and over Asia. Conversely, signals of anthropogenic aerosols and natural forcings cannot be detected in any of these indices at either global or continental scales.

Summary: This study evaluates model projections of rainfall variability change under global warming in different sub-regions of Brazil, showing a general agreement among models in predicting increased variability across various time scales. Future changes in Brazil are expected to include more rainfall variability, such as drier or wetter periods, even in areas where future changes in mean rainfall are uncertain.

Summary: The StRaHaS method aims to improve the accuracy and applicability of hydrologic modeling for individual rainwater harvesting systems. By analyzing random rainfall features, variable water demands, and other characteristics, it derives models for water balance variations, post-rainfall storage probability, and system reliability. The method outperforms existing methods in accuracy and simplicity, and shows promising results in enhancing the reliability and sustainability of rainwater harvesting systems.

Summary: South European and Mediterranean countries, particularly the regions around the Mediterranean, have long suffered from water scarcity. In the Cyclades region, the historical effects of drought have been addressed through small-scale rainwater harvesting. Despite the use of desalination plants, rainwater harvesting remains a vital and sustainable water source for the Cycladic islands. This research investigates the future performance of rainwater harvesting applications and their contribution to continuous, sustainable, and climate-resilient water supply in the region.

Summary: This study investigates the impacts of climate change on a rainwater harvesting (RWH) system using data from eight Australian capital cities. The findings show that the water savings and reliability of the RWH system will slightly reduce in the future period, with different performance levels across cities. The results of this study are useful for water authorities and policymakers in planning sustainable RWH systems under changing climate conditions.

Summary: The study of rainfall trends in Alagoas state, Northeast of Brazil, provides important information for food security and water availability. The research found a general decrease in rainfall during the rainy period and an increase in the dry period, especially in the driest region. Breakpoints in the rainfall series were mostly observed during periods of significant variations in climate variability modes, with the Monthly Nino3.4 Index and the Southern Oscillation Index having a strong influence. The changes detected can help inform public policies on water resources and guide future studies.

Summary: This study proposes a traditional tipping-bucket rain gauge based on manifold triboelectric nanogenerator units to address the low measurement accuracy and severe abrasion issues of traditional rain gauges. Experimental results demonstrate that the proposed rain gauge has real-time measurement ability, high resolution, and rainwater energy harvesting function.

Summary: This study examines the complex relationships between climate change, land use/land cover changes, and the prevalence of vector-borne and waterborne diseases in Coimbatore district, Tamil Nadu, India. The study reveals an increase in built-up areas and temperature, as well as a decrease in agricultural land. It also shows a growing trend in dengue and diarrhoeal diseases, which correlate strongly with the increase in built-up areas and temperature. This research is vital for policy decisions in public health, urban planning, and climate change mitigation.
