Over the millennia, indigenous small tanks (small reservoirs or ponds) have served to store rainwater and surface runoff irrigate drylands. However, despite their significance, been gradually abandoned in drylands over past decades expand cultivable areas under modern agricultural interventions, such as dam canal systems. Sole reliance on water interventions has intensified freshwater stress rendered dryland agriculture vulnerable droughts. Herein, we present a sociohydrological model incorporating concept of human salience (i.e., attention accorded by farmers based actual perceived reservoir availability rainfall) access simulate farmer decisions cultivation area. By applying centrally managed irrigation system quasi-decentralized Mahaweli H scheme Sri Lankan dry zone for 2010–2020 period, calibrated perception levels show that perceive significantly low rainfall threshold indicating greater adaptability conditions. Sensitivity area demonstrate an 18% higher dependency compared when deciding This stark is rooted lack accessibility tanks, feature enhance drought resilience system. While providing quantifiable insights, this comparative assessment underscores importance critically evaluating efficacy decentralized current resource investments.

The importance of biome in shaping urban biodiversity

Trends in Ecology & Evolution, Год журнала: 2025, Номер unknown

Humanity is urbanizing, with vast implications on natural systems. To date, most research urban biodiversity has centered temperate biomes. Conversely, drylands, collectively the largest terrestrial global biome, remain understudied. Here, we synthesize key mechanistic differences of urbanization's impacts across these Irrigation shapes dryland ecology, and can lead to greener, sometimes more biodiverse, landscapes than local wildlands. These green patches in drylands often have a different species composition, including many non-native human-commensal species. Socioeconomic factors - locally globally mediate how biomes shape patterns through effects irrigation, greening, invasive We advocate for low-income cities, implementing biome-specific, scientifically grounded management policies.
