A number of intersecting crises are currently ongoing at multiple scales, including increasing inequality, environmental degradation, and climate destabilization, as well as new surges of populism and mounting public health threats. These emergencies question our economic model of past decades and provoke a rethinking of the general approach to economic policy from a multi-scalar perspective. In this article, we compare two approaches aiming to rethink economic development policy: foundational economy and Doughnut economics, and consider if and how they complement each other. We conclude that the two approaches are potentially complementary, most prominently in their call for high-income countries to refocus from growth per se to purpose-driven economic strategies that prioritize public services and redistribute incomes. However, they differ in respect to their geographical focus, environmental concerns, and application. To properly address tradeoffs between social needs and environmental effects, foundational scholarship would benefit from deeper engagement with the socioenvironmental perspective presented in Doughnut economics, which stresses the need to consider human-nature interlinkages. In sum, combining different aspects of the two approaches promises to provide a more robust response to contemporary challenges, especially for local policy making.

Growing social inequalities, political unrest and environmental degradation over the last decade have forced local governments to rethink existing models of urban and economic development. Since the financial crisis of 2008, the Social and Solidarity Economy (SSE) has gained increasing attention from grassroots organizations, policy makers and local governments as a way of conducting economic activities that prioritize social and environmental objectives over financial profit. [...]of austerity policies and the bankruptcy of the welfare state in Spain since the financial crisis in 2008, both the state and private market have been greatly criticized for being unable to properly respond to social needs. According to representatives of the local government, it is among these groups that the policies has had one of its greatest impacts but also where it is hardest to establish the SSE.

We present in situ Cassini Radio Plasma Wave Science observations in the vicinity of Enceladus and in the E ring of Saturn that indicate the presence of dusty plasma. The four flybys of Enceladus in 2008 revealed the following cold plasma characteristics: (1) there is a large plasma density (both ions and electrons) within the Enceladus plume region, (2) no plasma wake effect behind Enceladus was detected, (3) electron densities are generally much lower than the ion densities in the E ring (ne/ni < 0.5) as well as in the plume (ne/ni < 0.01), and (4) the average bulk ion drift speed is significantly less than the corotation speed and is instead close to the Keplerian speed. These signatures result from half or more of the electrons being attached to dust grains and by the interaction between the surrounding cold plasma and the predominantly negatively charged submicrometer‐sized dust grains. The dust and plasma properties estimated from the observations clearly show that the dust‐plasma interaction is collective. This strong dust‐plasma coupling appears not only in the Enceladus plume but also in the Enceladus torus, typically from about 20 RE (∼5000 km) north and about 60 RE (∼15,000 km) south of Enceladus. We also suggest that the dust‐plasma interaction in the E ring is the cause of the planetary spin‐modulated dynamics of Saturn's magnetosphere at large. Key Points Enceladus plume created a large amount of plasma Small dust surrounding Enceladus is negatively charged Charged dust and ions are strongly coupled around Enceladus

The Cassini Langmuir probe, part of the Radio and Plasma Wave Science (RPWS) instrument, has provided a wealth of information about the cold and dense plasma in the Saturnian system. The analysis of the ion side current (current for negative potentials) measured by the probe from 2005 to 2008 reveals also a strong sensitivity to energetic electrons (250–450 eV). These electrons impact the surface of the probe, and generate a detectable current of secondary electrons. A broad secondary electrons current region is inferred from the observations in the dipole L Shell range of ∼6–10, with a peak full width at half maximum (FWHM) at L = 6.4–9.4 (near the Dione and Rhea magnetic dipole LShell values). This magnetospheric flux tube region, which displays a large day/night asymmetry, is related to the similar structure in the energetic electron fluxes as the one measured by the onboard Electron Spectrometer (ELS) of the Cassini Plasma Spectrometer (CAPS). It corresponds spatially to both the outer electron radiation belt observed by the Magnetosphere Imaging Instrument (MIMI) at high energies and to the low‐energy peak which has been observed since the Voyager era. Finally, a case study suggests that the mapping of the current measured by the Langmuir probe for negative potentials can allow to identify the plasmapause‐like boundary recently identified at Saturn, and thus potentially identify the separation between the closed and open magnetic field lines regions. Key Points The Cassini Langmuir probe is strongly sensitive to energetic electrons A secondary electrons current region was detected by the Cassini Langmuir probe The LP can help to identify the plasmapause‐like boundary at Saturn
