Most of South America, particularly the region between southern Amazon and southeastern Brazil, as well a large part La Plata Basin, has its climate regulated by American Monsoon System. Extreme weather events in these areas have significant socioeconomic impacts. The Madeira, São Francisco, Paraná river basins, three major watersheds are especially vulnerable to wet drought periods due their importance freshwater ecosystems sources water for consumption, energy generation, agriculture. scarcity surface meteorological stations basins makes studies challenging, often using reanalysis satellite data. This study aims identify extreme (wet) (wet drought) during extended season (October March) from 1980 2022 evaluate performance two gridded datasets (CPC ERA5) determine which best captures observed patterns basins. Wet were identified 95th percentile, Standardized Precipitation Index (SPI) on 6-month scale. In general, CPC data showed slightly superior compared ERA5 reproducing statistical measures. For day precipitation, both captured time series pattern, but better reproduced values trends. results also indicate decrease an increase events.

The Andes is the longest mountain range in world, stretching from tropical South America to austral Patagonia (12°N-55°S). Along with climate differences associated latitude, Andean region also features contrasting slopes and elevations, reaching altitudes of more than 4,000 m. a.s.l., a relatively narrow crosswise section, hosts diverse ecosystems human settlements. This complex landscape poses great challenge weather simulations. interaction topography large-scale atmospheric motions controls meteorological phenomena at scales few kilometers, often inadequately represented global (grid spacing ∼200–50 km) regional (∼50–25 simulations previously studied for Andes. These typically exhibit large biases precipitation, wind near-surface temperature over Andes, they are not suited represent strong gradients processes. In recent years (∼2010–2024), number modeling studies, including convection permitting simulations, have contributed our understanding characteristics distribution variety systems processes along orographic precipitation hotspots, circulations, gravity waves, among others.

Rural areas near large cities do not satisfy the food needs of city’s population. In Medellín, Colombia, these only 2% needs, highlighting an urgent need to review and improve policies supporting agriculture. This study was conducted over a ten-year period since release Medellín policy related land use. The model uses agent-based modelling, geographic analysis dichotomous variables, combining structures create decision-making element thus identify changes examine in relation current use detect properties with potential for conversion agricultural By evaluating post-processed layers, rural environments is prioritized, setting up clusters homogeneous zones finding new influence. implications this extend beyond offering that can be applied other regions facing similar challenges productivity research supports informed effective policy, contributing improved security sustainable development. results show some are susceptible provide framework revision local regulations, serving as support tool public by giving administration key factors update policies. findings relevant stakeholders, including policymakers landowners, suggesting several promoting agriculture Also, approach promotes efficient agriculture, importance modelling planning evaluation.

This paper explores the global impacts of climate change and pollution across diverse regions, highlighting unique challenges innovative initiatives. From rising temperatures severe droughts in Africa Australia to melting glaciers Arctic Asia, each continent faces significant environmental threats. Despite these challenges, countries are making strides renewable energy, conservation, community-based actions. International agreements local indigenous practices play vital roles efforts. The concludes with a call for continued cooperation action, emphasizing potential sustainable future through collective innovation resilience-building. Through this comprehensive analysis, underscores urgency possibility addressing warming healthier planet.
