Environmental footprint family to address local to planetary sustainability and deliver on the SDGs
The number of publications on environmental footprint indicators has been growing rapidly, but with limited efforts to integrate different footprints into a coherent framework. Such integration is important for comprehensive understanding of environmental issues, policy formulation and assessment of trade-offs between different environmental concerns. Here, we systematize published footprint studies and define a family of footprints that can be used for the assessment of environmental sustainability. We identify overlaps between different footprints and analyse how they relate to the nine planetary boundaries and visualize the crucial information they provide for local and planetary sustainability. In addition, we assess how the footprint family delivers on measuring progress towards Sustainable Development Goals (SDGs), considering its ability to quantify environmental pressures along the supply chain and relating them to the water-energy-food-ecosystem (WEFE) nexus and ecosystem services. We argue that the footprint family is a flexible framework where particular members can be included or excluded according to the context or area of concern. Our paper is based upon a recent workshop bringing together global leading experts on existing environmental footprint indicators
First insights into the phylogenetic diversity of Mycobacterium tuberculosis in Nepal
BACKGROUND: Tuberculosis (TB) is a major public health problem in Nepal. Strain variation in Mycobacterium tuberculosis may influence the outcome of TB infection and disease. To date, the phylogenetic diversity of M. tuberculosis in Nepal is unknown. METHODS AND FINDINGS: We analyzed 261 M. tuberculosis isolates recovered from pulmonary TB patients recruited between August 2009 and August 2010 in Nepal. M. tuberculosis lineages were determined by single nucleotide polymorphisms (SNP) typing and spoligotyping. Drug resistance was determined by sequencing the hot spot regions of the relevant target genes. Overall, 164 (62.8%) TB patients were new, and 97 (37.2%) were previously treated. Any drug resistance was detected in 50 (19.2%) isolates, and 16 (6.1%) were multidrug-resistant. The most frequent M. tuberculosis lineage was Lineage 3 (CAS/Delhi) with 106 isolates (40.6%), followed by Lineage 2 (East-Asian lineage, includes Beijing genotype) with 84 isolates (32.2%), Lineage 4 (Euro-American lineage) with 41 (15.7%) isolates, and Lineage 1 (Indo-Oceanic lineage) with 30 isolates (11.5%). Based on spoligotyping, we found 45 different spoligotyping patterns that were previously described. The Beijing (83 isolates, 31.8%) and CAS spoligotype (52, 19.9%) were the dominant spoligotypes. A total of 36 (13.8%) isolates could not be assigned to any known spoligotyping pattern. Lineage 2 was associated with female sex (adjusted odds ratio [aOR] 2.58, 95% confidence interval [95% CI] 1.42-4.67, p = 0.002), and any drug resistance (aOR 2.79; 95% CI 1.43-5.45; p = 0.002). We found no evidence for an association of Lineage 2 with age or BCG vaccination status. CONCLUSIONS: We found a large genetic diversity of M. tuberculosis in Nepal with representation of all four major lineages. Lineages 3 and 2 were dominating. Lineage 2 was associated with clinical characteristics. This study fills an important gap on the map of the M. tuberculosis genetic diversity in the Asian reg
Carbon stocks and dynamics at different successional stages in an Afromontane tropical forest
As a result of different types of disturbance, forests are a
mixture of stands at different stages of ecological succession. Successional
stage is likely to influence forest productivity and carbon storage, linking
the degree of forest disturbance to the global carbon cycle and climate.
Although tropical montane forests are an important part of tropical forest
ecosystems (ca. 8 %, elevation > 1000 m a.s.l.), there are still
significant knowledge gaps regarding the carbon dynamics and stocks of these
forests, and how these differ between early (ES) and late successional (LS)
stages. This study examines the carbon (C) stock, relative growth rate (RGR)
and net primary production (NPP) of ES and LS forest stands in an Afromontane
tropical rainforest using data from inventories of quantitatively important
ecosystem compartments in fifteen 0.5 ha plots in Nyungwe National Park in
Rwanda.
The total C stock was 35 % larger in LS compared to ES plots due to
significantly larger above-ground biomass (AGB; 185 and 76 Mg C ha−1
in LS and ES plots), while the soil and root C stock (down to
45 cm depth in the mineral soil) did not significantly differ between the
two successional stages (178 and 204 Mg C ha−1 in LS and ES plots). The main reasons for the difference in AGB were that ES trees
had significantly lower stature and wood density compared to LS trees.
However, ES and LS stands had similar total NPP (canopy, wood and roots of
all plots ∼ 9.4 Mg C ha−1) due to counterbalancing effects of
differences in AGB (higher in LS stands) and RGR (higher in ES stands). The
AGB in the LS plots was considerably higher than the average value reported
for old-growth tropical montane forest of south-east Asia and Central and
South America at similar elevations and temperatures, and of the same
magnitude as in tropical lowland forest of these regions.
The results of this study highlight the importance of accounting for
disturbance regimes and differences in wood density and allometry of tree
species dominating at different successional stages in an attempt to quantify
the C stock and sink strength of tropical montane forests and how they may
differ among continents
Belgium: Religions and Prisons in Law
In Belgium, the regulation of religion in prison has deeply changed over the past twenty years. Two major challenges have emerged: the first is the growing number of Muslim prisoners in Belgian prisons; the second is the question of the radicalization of some of these detainees. The terrorist events in Europe and Belgium have exacerbated these two challenges, which in turn have had repercussions on the prison regulation applied to all religions. The strengthening of the security rules has been done in a transversal and "non-discriminatory" way. All religious accommodations are now re-read against this security background more than in the context of international religious freedom requirements
Factors associated with research productivity in higher education institutions in Africa: a systematic review
National tuberculosis prevalence surveys in Africa, 2008\u20132016: an overview of results and lessons learned
Objective and methods: Worldwide, tuberculosis (TB) is the leading cause of death from a single infectious agent. In many countries, national TB prevalence surveys are the only way to reliably measure the burden of TB disease and can also provide other evidence to inform national efforts to improve TB detection and treatment. Our objective was to synthesise the results and lessons learned from national surveys completed in Africa between 2008 and 2016, to complement a previous review for Asia. Results: Twelve surveys completed in Africa were identified: Ethiopia (2010\u20132011), Gambia (2011\u20132013), Ghana (2013), Kenya (2015\u20132016), Malawi (2013\u20132014), Nigeria (2012), Rwanda (2012), Sudan (2013\u20132014), Tanzania (2011\u20132012), Uganda (2014\u20132015), Zambia (2013\u20132014) and Zimbabwe (2014). The eligible population in all surveys was people aged 6515 years who met residency criteria. In total 588 105 individuals participated, equivalent to 82% (range 57\u201396%) of those eligible. The prevalence of bacteriologically confirmed pulmonary TB disease in those 6515 years varied from 119 (95% CI 79\u2013160) per 100 000 population in Rwanda and 638 (95% CI 502\u2013774) per 100 000 population in Zambia. The male:female ratio was 2.0 overall, ranging from 1.2 (Ethiopia) to 4.1 (Uganda). Prevalence per 100 000 population generally increased with age, but the absolute number of cases was usually highest among those aged 35\u201344 years. Of identified TB cases, 44% (95% CI 40\u201349) did not report TB symptoms during screening and were only identified as eligible for diagnostic testing due to an abnormal chest X-ray. The overall ratio of prevalence to case notifications was 2.5 (95% CI 1.8\u20133.2) and was consistently higher for men than women. Many participants who did report TB symptoms had not sought care; those that had were more likely to seek care in a public health facility. HIV prevalence was systematically lower among prevalent cases than officially notified TB patients with an overall ratio of 0.5 (95% CI 0.3\u20130.7). The two main study limitations were that none of the surveys included people <15 years, and 5 of 12 surveys did not have data on HIV status. Conclusions: National TB prevalence surveys implemented in Africa between 2010 and 2016 have contributed substantial new evidence about the burden of TB disease, its distribution by age and sex, and gaps in TB detection and treatment. Policies and practices to improve access to health services and reduce under-reporting of detected TB cases are needed, especially among men. All surveys provide a valuable baseline for future assessment of trends in TB disease burden
