- Interventions to strengthen forest conservation in tropical biomes face multiple challenges. Insecure land tenure and unequal benefit sharing within forest user groups are two of the most important. Using original household level survey data from 130 villages in six countries, we assess how current wealth inequality relates to tenure security and benefit flows from forest use. We find that villages with higher wealth inequality report lower tenure security and more unequal flows from forest income and externally sourced income. Furthermore, we find that wealthier individuals within villages capture a disproportionately larger share of the total amount of forest benefits available to each village, while external income often benefits poorer individuals more. These findings suggest that unless future forest conservation interventions actively work to mitigate inequalities linked to existing forest benefit flows, there is a risk that these interventions-including those associated with REDD + activities reproduce or even aggravate pre-existing socioeconomic inequalities within user groups, potentially undermining both their conservation and economic objectives.

- BACKGROUND: The pattern of structural brain abnormalities in anorexia nervosa (AN) is still not well understood. While several studies report substantial deficits in gray matter volume and cortical thickness in acutely underweight patients, others find no differences, or even increases in patients compared with healthy control subjects. Recent weight regain before scanning may explain some of this heterogeneity. To clarify the extent, magnitude, and de-pendencies of gray matter changes in AN, we conducted a prospective, coordinated meta-analysis of multicenter neuroimaging data.METHODS: We analyzed T1-weighted structural magnetic resonance imaging scans assessed with standardized methods from 685 female patients with AN and 963 female healthy control subjects across 22 sites worldwide. In addition to a case-control comparison, we conducted a 3-group analysis comparing healthy control subjects with acutely underweight AN patients (n = 466) and partially weight-restored patients in treatment (n = 251).RESULTS: In AN, reductions in cortical thickness, subcortical volumes, and, to a lesser extent, cortical surface area were sizable (Cohen's d up to 0.95), widespread, and colocalized with hub regions. Highlighting the effects of un-dernutrition, these deficits were associated with lower body mass index in the AN sample and were less pronounced in partially weight-restored patients.CONCLUSIONS: The effect sizes observed for cortical thickness deficits in acute AN are the largest of any psychiatric disorder investigated in the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Consortium to date. These results confirm the importance of considering weight loss and renutrition in biomedical research on AN and underscore the importance of treatment engagement to prevent potentially long-lasting structural brain changes in this population.
