Doing More With Less: Cutting Food Loss and Waste in the EU and Its Impact on Food Security

open access: yesSustainable Development, EarlyView.
ABSTRACT In September 2025, the European Parliament and Council signed the law of the Revision of the EU waste framework directive, which includes also reductions for food loss and waste (FLW). This comes at a time of concern over the EU's strategic autonomy for its agrifood sector.

Neoclassical transport theory of a multispecies plasma in the low collision frequency regime

open access: yesThe Physics of Fluids, 1975
A comprehensive neoclassical transport theory for a multispecies plasma in the low collision frequency banana regime is developed. A recently developed approximate collision operator is used to analytically calculate the transport coefficients in a nonisothermal, finite beta plasma for arbitrary mass ratios and all values of the aspect ratio.

Investigation of multi-ion heat and neoclassical transport using new edge main ion measurements at ASDEX Upgrade

open access: yesNuclear Fusion
This study provides new insights into multi-ion heat transport and the validation of neoclassical theory at the edge of H-mode plasmas. Utilizing a high-resolution main ion charge exchange recombination spectroscopy system, the first characterization of ...

Global effects on neoclassical transport in the pedestal with impurities

open access: yes, 2016
We present a numerical study of collisional transport in a tokamak pedestal in the presence of non-trace impurities, using the radially global $\delta f$ neoclassical solver PERFECT [M. Landreman et al. 2014 Plasma Phys. Control. Fusion 56 045005]. It is

Influences on Sustainable Consumption Behavior: A Pairwise Evaluation of Price and Greenness Sensitivity

open access: yesSustainable Development, EarlyView.
ABSTRACT Identifying the factors that influence sustainable purchasing behavior is an important step in understanding the phenomenon and informing industry efforts to promote sustainable consumption. This study aims to develop a situation‐ and context‐specific model that explains sustainable purchasing behavior by drawing on three distinct theoretical ...

Radiative damping of toroidal Alfvén eigenmode in low-shear plasmas

open access: yesFundamental Plasma Physics
Instabilities of Alfvén eigenmodes (AEs) are of significant concern because they can enhance the cross-field transport of fusion-born alpha particles beyond the neoclassical level in magnetic fusion plasmas. The threshold value of alpha-particle pressure

Neoclassical flows in deuterium-helium plasma density pedestals

open access: yes, 2017
In tokamak transport barriers, the radial scale of profile variations can be comparable to a typical ion orbit width, which makes the coupling of the distribution function across flux surfaces important in the collisional dynamics.

L-H transition dynamics in fluid turbulence simulations with neoclassical force balance [PDF]

open access: yes, 2013
Spontaneous transport barrier generation at the edge of a magnetically confined plasma is investigated. To this end, a model of electrostatic turbulence in three-dimensional geometry is extended to account for the impact of friction between trapped and ...

Blue‐Prints for Ocean Governance: Analyzing Resource Sustainability in International Blue Economic Frameworks

open access: yesSustainable Development, EarlyView.
ABSTRACT Championed as a pathway for sustainable growth, the “blue economy” (BE) has garnered increasing interest in recent decades. International organizations like the World Bank and the Organization for Economic Cooperation and Development (OECD) increasingly point to marine resources and activities as a “new frontier” for economic growth ...
