Climate Services

• An operational EWS was successfully established in Colombia. • Over 4 million inhabitants can benefit from the information provided by the EWS. • SIATA combines technical, scientific and social expertise. • SIATA is a success story, a benchmark for innovation, and an example for many other cities. There is an urgent need to implement adaptation measures for weather, climate, and compound extrem…

This study aims to investigate the impact of climate change on watershed Best Management Practices (BMPs). To achieve this, a SWAT model was developed for the Hanjiang River Basin, incorporating climate model data from CMIP6 under different climate scenarios (SSP2-4.5 and SSP5-8.5). Using 2000–2019 as the historical baseline, the study simulated and evaluated the effectiveness of 10 BMPs in reduc…

Across local governments, evidence based adaptation has institutionalized vulnerability and risk assessments in planning, yet structural constraints persist and an additional gap emerges at implementation. Nationally mandated vulnerability and risk assessment tools used in LCCAMs function as a national climate service that delivers standardized climate risk information for local adaptation decisi…

Climate change is a growing threat severely impacting crop production and productivity in East and West Africa. However, evidence comparing the nature of the impact and adaptive measures between the regions is scarce. This scientific research primarily focuses on characterizing patterns of crop production and productivity, reviewing the climate change impacts on crop production systems, and asses…

Drought propagation mechanisms in sandy lands remain insufficiently understood, particularly regarding the dynamic thresholds and integrated processes linking meteorological, hydrological, and agricultural droughts. To address this gap, this study investigates the spatiotemporal evolution, propagation characteristics, and triggering conditions of drought in the Mu Us Sandy Land (MUSL) from 1982 t…

• The study explored climate change adaptation measures in coffee-based farming systems and their key determinants. • A cross-sectional household survey was combined with longitudinal climate data. • Temperature and rainfall showed increasing trends, which aligned with farmers’ perceptions. • Rainfall irregularities were identified as the major climatic risk to coffee production. • Farmers adopte…

Decadal climate predictions are a source of information to anticipate the evolution of the climate system on timescales from 1 to 10 years ahead. Since these predictions are often produced at coarser resolutions than ideal, statistical downscaling techniques can be employed to enhance their spatial resolution. This study assesses the effectiveness of various statistical downscaling methods applie…

Climate services are often positioned as tools to enhance resilience, guide policy, and enable decision-making in the face of climate variability. However, these framings rarely interrogate the social underpinnings of what climate services are for, how their demand arises, and in what ways they become embedded in the routines of life, governance, and planning. Taking inspiration from social pract…

• Climate variability affects livestock productivity, vital to rural livelihoods and food security in Benin. • Herders’ views on climate change closely matched rainfall and temperature anomalies. • Crop residues as feed and mobility were key strategies to reduce climate impacts on livestock. • Adaptation strategies varied by phytogeographic zone and zebu proportion in the herd. • Insights guide l…

Whilst skilful seasonal climate forecasts are routinely produced, their ability to support profitable agricultural decision-making remains uncertain, particularly in regions with modest seasonal predictability and high climate variability. We assess the financial implications of using a statistically derived seasonal maize crop-yield forecast for a medium-size commercial farm in South Africa, foc…

Smallholder coffee farming in tropical highlands is increasingly threatened by climate change. This study examines the trends and potential effects of climate extreme indices on coffee farming households in the Kafa Biosphere Reserve using daily rainfall and temperature data (1985–2023). Twelve extreme climate indices (six temperature and six rainfall indices) were computed from Ethiopian Meteoro…
