Summary: To effectively manage drought in the Niger River Basin, decision-makers need to distinguish dry spells from drought and establish thresholds to determine the severity of drought and implement appropriate water resource management measures. This study utilizes precipitation reanalysis records to establish index- and percentiles-based thresholds for defining dry spell and drought. The results provide operational criteria for early drought detection.

Summary: This research aims to evaluate and mitigate the risks of flood events in the El Bayadh region. Eight different frequency analysis distributions were used to develop rainfall intensity-duration-frequency and flood risk-duration-frequency curves. The results show that high-intensity rainfall lasts for short durations, while high flood risk lasts for intermediate durations.

Summary: The study demonstrates that increased rainfall amounts with prolonged dry intervals can promote Leymus chinensis biomass production by increasing soil moisture, while prolonged dry intervals with increased precipitation per event may decrease the available soil nitrogen content. Different rainfall patterns can affect the biomass production of Leymus chinensis.

Summary: The frequency of different classes of dry spells during the rainy season is related to the occurrence of dry, normal, and wet years in semi-arid areas, and is influenced by long-duration El Nino and La Nina events. These factors have significant impacts on maize productivity.

Summary: China's dry-land farming system utilizes plastic film mulching and natural rainfall to counteract drought damage. Implementing deficit irrigation modes combined with specific planting models can significantly increase wheat production, with the impact on dry matter translocation and radiation use efficiency (RUE) remaining unknown. Field trials from 2016 to 2018 demonstrated that the ridge furrow rainfall harvesting system (RF) with deficit irrigation at the jointing and flowering stages (IJF) greatly improved soil moisture, leading to higher LAI, In value, IPAR, RUE, and PAR capture ratio compared to traditional flat cultivation with no irrigation (TF-NI). The RF-IJF treatment showed the highest gains in biomass translocation, grain yield, and RUE.

Summary: Livestock are vital in the mixed farming system in the study area, providing power, nutrition, income, employment, and poverty alleviation. However, feed shortage, especially during the dry season, hinders productivity. Farmers mainly rely on natural pasture, crop residues, stubble grazing, and roadside grasses for feed, with few practicing improved forage cultivation due to land constraints and lack of knowledge. Coping strategies for feed scarcity include conservation, purchase of roughages, herd reduction, and renting grazing land. Major constraints to livestock production are feed shortage, diseases, and low productivity of local breeds, suggesting a need for institutional and technological interventions.

Summary: To find suitable farming management approaches in the semi-arid climate of Iran, an experiment combining three farm management practices with four crop rotation systems was set up. The results showed that using the integrated farming method increased chlorophyll content and improved wheat grain quality and quantity. Farming with organic matter inputs had higher protein contents compared to using inorganic inputs.

Summary: In Sweden, drainage and water infrastructure construction have had both positive and negative impacts on agriculture in the last few centuries. A recent trend in constructing wetlands for water retention, nutrient reduction, and biodiversity enhancement has been observed. This pilot study utilized remote sensing techniques to identify and analyze water retention structures in Gotland Lan and Kalmar Lan, showing an increasing trend in the number of structures, predominantly located in smaller areas and downstream regions. The study also highlighted discrepancies between remote sensing data and the Swedish Meteorological and Hydrological Institute database, emphasizing the importance of higher resolution imagery in similar studies.

Summary: Water scarcity is a growing challenge in semi-arid and sub-humid areas. Small reservoirs (SRs) in West Africa play an important role in improving food security, livelihoods, and income diversification. However, their productivity is below potential, and water quality and quantity monitoring is insufficient.

Summary: The United Nations Food Systems Summit has not given sufficient consideration to the role of water in food systems transformation, despite its essentiality. This is of even greater importance due to the worsening impacts of climate change on food systems, which are mediated through water. To prevent water from breaking food systems, key actors should focus on protecting water-dependent ecosystems, improving agricultural water management, reducing water and food losses, coordinating water interventions with nutrition and health, enhancing the environmental sustainability of food systems, addressing social inequities, and improving data quality and monitoring for water-food system linkages.

Summary: Recent studies have found that using laser diffraction method (LDM) for soil particle size analysis can yield compatible results with traditional methods, but requires transformation of clay-silt particle size cutoff. This study tested a combination of approaches for determining LDM values on soil samples and compared the results with sieve and pipette method (SPM). The findings are promising for routine soil analyses, but more research is needed for different types of soils.

Summary: Rainfed smallholder farming is vulnerable to climate change, and understanding the complexity of environmental, societal, and human systems can reduce vulnerability and increase resilience. However, there are challenges in applying resilience frameworks to address climate-related issues in poverty-affected rural communities with degraded livelihood systems. Addressing these challenges may require external factors in addition to local action.
