“Perceptions of river health are strongly influenced by expectations regarding a natural river. Many observers expect clear water, a slightly sinuous river with pools and riffles, and some riparian trees. River health, however, is much more complicated and multifaceted. The physical appearance of a river, for example, depends strongly on geomorphic context and river history. [The H/T] use mountainous headwater rivers in Colorado to examine the influence of physical complexity on river health. Complexity can be described with respect to the stream bed, banks, cross-sectional form, and planform of the river and floodplain. The configuration of each of these components of a riverine system has implications for habitat abundance and diversity, sensitivity and resilience of the river to natural and human-induced disturbances, retention of water, sediment and nutrients, and connectivity within the riverine system and between the river and adjacent uplands. Many types of resource use simplify rivers to the point that the river undergoes a metamorphosis, or a thorough, sustained change in channel form and function. Loss of beaver dams and channel-spanning logjams in mountainous headwater rivers in Colorado, for example, has resulted in metamorphosis of physically complex, anastomosing channels that were highly connected to adjacent floodplains. These rivers have assumed an alternate stable state as single-thread channels with limited retention and resilience. Effective, sustainable river restoration involves (i) characterizing the magnitude of different forms of physical complexity naturally present in a particular river segment, (ii) understanding the effects of physical complexity on river ecosystem function, and (iii) assessing the degree to which this level of physical complexity can be restored or mimicked. An important part of this process may be educating stakeholders regarding the importance of physical complexity – messiness – in healthy rivers…”

“Practitioners can use the products from this report to identify areas within the Landward Migration Zones (LMZ) of Oregon estuaries where early action is likely to yield the greatest long-term benefits. Active restoration, along with land use planning that accommodates future tidal wetlands, can provide ecological function and help human communities adapt to sea level rise. To support these decisions, [the report's authors] integrated the LMZ data with additional spatial datasets describing the potential ecological functions of current and future estuary areas, as well as social and demographic information related to coastal hazard resilience, population density, and infrastructure distribution…”

“[The authors:]
• Developed a multi-stressor framework with 32 agriculture-relevant weather indices and integrated them into two composite metrics: Weather Stress Divergence and Weather Stress Similarity, capturing deviations from and spatial correspondence with historical weather stress patterns.
• Using an agroecological-zone-specific weighted averaging framework, the framework minimized index redundancy while accounting for the regional importance of individual stressors.
• Adapted the concept of climate velocity to an agricultural context to assess how current weather stress patterns differ from historical conditions and how their spatial correspondence is changing over time.
KEY FINDINGS:
🌾 More than 50% of CONUS cropland experienced increasing weather stress divergence.
🌡️ Drought and extreme heat were the primary contributors to high divergence.
📉 Current weather regimes are becoming increasingly dissimilar to historical patterns…”

[not my usual fare, but fascinating - and not in a good way :/ … not trying to be trite, but hydrology / water resources are crucial across so many areas]

“🌵🧠 Drought can disrupt livelihoods, strain communities, increase financial stress, and deepen uncertainty. All of these are factors that may contribute to psychological distress.
📊 Yet in the U.S., the relationship between drought and suicide mortality has remained understudied. This nationwide study examined drought and suicide deaths across the contiguous U.S. from 2000–2018.
🌾 The study measured drought severity using the Evaporative Demand Drought Index and used suicide mortality data from the National Center for Health Statistics.
📈 Both firearm and non-firearm suicide mortality were positively associated with drought, especially under severe conditions.
⚠️ Severe drought was associated with higher suicide mortality across several subgroups, including older adults, women, and people living in non-metro areas, though subgroup findings were not statistically compared.
🛡️ Climate-related hazards can affect health through social, economic, and psychological pathways, not only through physical exposure. Drought preparedness should include mental health supports, rural outreach, financial stress interventions, and suicide prevention resources tailored to communities facing prolonged environmental stress…”
