Diversification or loading order? Divergent water-energy politics and the contradictions of desalination in Southern California (1935-2018)
This paper explores the contradictory and sometimes incompatible imperatives towards enhancing water supply reliability and addressing the water-energy nexus. Using the highly contested development of seawater desalination for municipal water supply in the San Diego metropolitan region as an analytical entry point, the paper excavates divergent water-energy politics emerging in California. Two underlying paradigm shifts of water governance are identified. First, supply diversification represents an attempt to increase reliability through the development of multiple decentralised water sources. Second, the notion of a loading order is being promoted by certain groups as a way of prioritising different water source options according to sustainability criteria, including energy footprint. Drawing on the concept of the socio-ecological fix, the paper argues that seawater desalination - as a technological adaptation to water stress - occupies a paradoxical position, being consistent with diversification, but representing a water-energy trade-off inconsistent with the loading order. This has resulted, the paper suggests, in a polarised debate between desalination and wastewater recycling as alternative climate-independent sources of freshwater. As such, the disputes over desalination in San Diego are understood to be a crucible for broader politics of resource governance transitions.

Tapping the oceans : seawater desalination and the political ecology of water
Tapping the Oceans provides a detailed analysis of the political and ecological debates facing water desalination in the twenty-first century. Water supplies for cities around the world are undergoing profound geographical, technological and political transformations. Increasingly, water-stressed cities are looking to the oceans to fix unreliable, contested and over-burdened water supply systems. Yet the use of emerging desalination technologies is accompanied by intense debates on their economic cost, governance, environmental impact and poses wider questions for the sustainable and just provision of urban water. Through a series of cutting-edge case studies and multi-subject approaches, this book explores the perspectives, disputes and politics surrounding water desalination on a broad geographical scale. As the first book of its kind, this unique work will appeal to those researching water and infrastructure issues in the fields of political ecology, geography, environmental science and sustainability. Industry and water managers who wish to understand the political debates around desalination technology more fully will also find this an informative read.

The First JWST View of a 30-Myr-old Protoplanetary Disk Reveals a Late-stage Carbon-rich Phase
We present a JWST MIRI/MRS spectrum of the inner disk of WISE J044634.16–262756.1B (hereafter J0446B), an old (∼34 Myr) M4.5 star but with hints of ongoing accretion. The spectrum is molecule-rich and dominated by hydrocarbons. We detect 14 molecular species (H2, CH3, CH4, C2H2, 13CCH2, C2H4, C2H6, C3H4, C4H2, C6H6, HCN, HC3N, CO2, and 13CO2) and two atomic lines ([Ne ii] and [Ar ii]), all observed for the first time in a disk at this age. The detection of spatially unresolved H2 and Ne gas strongly supports that J0446B hosts a long-lived primordial disk, rather than a debris disk. The marginal H2O detection and the high C2H2/CO2 column density ratio indicate that the inner disk of J0446B has a very carbon-rich chemistry, with a gas-phase C/O ratio ≳2, consistent with what has been found in most primordial disks around similarly low-mass stars. In the absence of significant outer disk dust substructures, inner disks are expected to first become water-rich due to the rapid inward drift of icy pebbles and evolve into carbon-rich as outer disk gas flows inward on longer timescales. The faint millimeter emission in such low-mass star disks implies that they may have depleted their outer icy pebble reservoir early and already passed the water-rich phase. Models with pebble drift and volatile transport suggest that maintaining a carbon-rich chemistry for tens of Myr likely requires a slowly evolving disk with α-viscosity ≲10−4. This study represents the first detailed characterization of disk gas at ∼30 Myr, strongly motivating further studies into the final stages of disk evolution.

Cosmic Cascades: How Disk Substructure Regulates the Flow of Water to Inner Planetary Systems
The influx of icy pebbles to the inner regions of protoplanetary disks constitutes a fundamental ingredient in most planet formation theories. The observational determination of the magnitude of this pebble flux and its dependence on disk substructure (disk gaps as pebble traps) would be a significant step forward. In this work, we analyze a sample of 21 T Tauri disks (with ages ≈0.5–2 Myr) using JWST/MIRI spectra homogeneously reduced with the JDISCS pipeline and high-angular-resolution Atacama Large Millimeter/submillimeter Array (ALMA) continuum data. We find that the 1500/6000 K water line flux ratio measured with JWST—a tracer of cold water vapor and pebble drift near the snow line—correlates with the radial location of the innermost dust gap in ALMA continuum observations (ranging from 8.7 to 69 au), confirming predictions from recent models that study connections between the inner and outer disk reservoirs. We develop a population synthesis exploration of pebble drift in gapped disks and find a good match to the observed trend for early and relatively effective gaps, while scenarios where pebble drift happens quickly, gaps are very leaky, or where gaps form late, are all disfavored on a population level. Inferred snow line pebble mass fluxes (ranging between 10−6 and 10−3 M⊕ yr−1 depending on gap position) are comparable to fluxes used in pebble accretion studies and those proposed for the inner solar system, while system-to-system variations suggest differences in the emerging planetary system architectures and water budgets.

Effective interdisciplinary stakeholder engagement in net zero building design
Stakeholder engagement is crucial to the design and construction stages of net zero buildings, requiring interdisciplinary collaboration to promote the integrated design process. The double diamond method is used to structure three briefing methods, deployed as stakeholder engagement to promote the integrated design process and identify pathways to regional, socio-technical knowledge utilisation. Stakeholders in three medium-sized, early stage, construction projects in the UK, Ireland and Rwanda included a range of construction professionals, facility users and policymakers. A consultation survey evidenced recurrent themes of professional agency in responding to the climate emergency and importance of carbon reduction through quality project delivery. A participatory workshop established systemic connections of building performance spanning concept, design, construction and operation life-cycle stages which encompassed technical, environmental, economic and social considerations of performance. A priority weighting workshop evidenced cross-case dominance of the provision of healthy environments relative to carbon and economic targets. A range of participation benefits was evidenced from a longitudinal evaluation of participation in the study. Future research directions for net zero buildings and the integrated design process include the use of decision-analysis methods. Practice relevance A practical approach is provided for project teams to enable interdisciplinary collaboration between construction professionals, clients and policymakers in early-stage net zero building projects. A framework of structured engagement activities helps stakeholders identify performance ambitions (survey), clarify priorities (workshop) and explore systemic performance issues across the building life-cycle, balancing also environmental, social and cost aspects (workshop). The findings highlight the importance of leadership from clients and proactive design teams in embedding sustainability and innovation. The workshops presented in this study can be adapted by practitioners to explore trade-offs, build shared understanding and identify opportunities for using local low-carbon materials. Applying the double diamond method simply but effectively enables the generation, discussion and refinement of diverse stakeholder knowledge during the early project stages. The paper demonstrates how participation benefits can be tracked over time. Practitioners will find guidance for making stakeholder engagement more purposeful and impactful in delivering holistic net zero buildings.

Tracing Pebble Drift History in Two Protoplanetary Disks with CO Enhancement
Pebble drift is an important mechanism for supplying the materials needed to build planets in the inner region of protoplanetary disks. Thus, constraining pebble drift’s timescales and mass flux is essential to understanding planet formation history. Current pebble drift models suggest pebble fluxes can be constrained from the enhancement of gaseous volatile abundances when icy pebbles sublimate after drifting across key snowlines. In this work, we present Atacama Large Millimeter/submillimeter Array observations of spatially resolved 13C18O J = 2–1 line emission inside the midplane CO snowline of the HD 163296 and MWC 480 protoplanetary disks. We use radiative transfer and thermochemical models to constrain the spatial distribution of CO gas column density. We find that both disks display centrally peaked CO abundance enhancement of up to 10 times of the Interstellar Medium (ISM) abundance levels. For HD 163296 and MWC 480, the inferred enhancements require 250–350 and 480–660 M⊕ of pebbles to have drifted across their CO snowlines, respectively. These ranges fall within cumulative pebble mass flux ranges to grow gas giants in the interior to the CO snowline. The centrally peaked CO enhancement is unexpected in current pebble drift models, which predict CO enhancement peaks at the CO snowline, or is uniform inside the snowline. We propose two hypotheses to explain the centrally peaked CO enhancement, including a large CO desorption distance and CO trapped in water ice. By testing both hypotheses with the 1D gas and dust evolution code chemcomp, we find that volatile trapping (about 30%) best reproduces the centrally peaked CO enhancement observed.
