RESUMEN

In this perspective, we draw on recent scientific research on the coffee leaf rust (CLR) epidemic that severely impacted several countries across Latin America and the Caribbean over the last decade, to explore how the socioeconomic impacts from COVID-19 could lead to the reemergence of another rust epidemic. We describe how past CLR outbreaks have been linked to reduced crop care and investment in coffee farms, as evidenced in the years following the 2008 global financial crisis. We discuss relationships between CLR incidence, farmer-scale agricultural practices, and economic signals transferred through global and local effects. We contextualize how current COVID-19 impacts on labor, unemployment, stay-at-home orders, and international border policies could affect farmer investments in coffee plants and in turn create conditions favorable for future shocks. We conclude by arguing that COVID-19's socioeconomic disruptions are likely to drive the coffee industry into another severe production crisis. While this argument illustrates the vulnerabilities that come from a globalized coffee system, it also highlights the necessity of ensuring the well-being of all. By increasing investments in coffee institutions and paying smallholders more, we can create a fairer and healthier system that is more resilient to future social-ecological shocks.

RESUMEN

The trend of emerging biorefineries is to process the harvest as efficiently as possible and without any waste. From the most valuable phytomass, refined medicines, enzymes, dyes and other special reactants are created. Functional foods, food ingredients, oils, alcohol, solvents, plastics, fillers and a wide variety of other chemical products follow. After being treated with nutrient recovery techniques (for fertilizer production), biofuels or soil improvers are produced from the leftovers. Economic optimization algorithms have confirmed that such complex biorefineries can be financially viable only when a high degree of feedstock concentration is included. Because the plant material is extremely voluminous before processing, the farming intensity of special plants increases in the nearest vicinity of agglomerations where the biorefineries are built for logistical reasons. Interdisciplinary analyses revealed that these optimization measures lead to significantly increased pollen levels in neighbouring urban areas and subsequently an increased risk of allergies, respectively costs to the national health system. A new moral dilemma between the shareholder's profit and public interest was uncovered and subjected to disputation.

RESUMEN

IMPORTANCE: Given scrutiny over financial conflicts of interest in health care, it is important to understand the types and distribution of industry-related payments to physicians. OBJECTIVE: To determine the types and distribution of industry-related payments to physicians in 2015 and the association of physician specialty and sex with receipt of payments from industry. DESIGN, SETTING, AND PARTICIPANTS: Observational, retrospective, population-based study of licensed US physicians (per National Plan & Provider Enumeration System) linked to 2015 Open Payments reports of industry payments. A total of 933 295 allopathic and osteopathic physicians. Outcomes were compared across specialties (surgery, primary care, specialists, interventionalists) and between 620 166 male (66.4%) and 313 129 female (33.6%) physicians using regression models adjusting for geographic Medicare-spending region and sole proprietorship. EXPOSURES: Physician specialty and sex. MAIN OUTCOMES AND MEASURES: Reported physician payment from industry (including nature, number, and value), categorized as general payments (including consulting fees and food and beverage), ownership interests (including stock options, partnership shares), royalty or license payments, and research payments. Associations between physician characteristics and reported receipt of payment. RESULTS: In 2015, 449 864 of 933 295 physicians (133 842 [29.8%] women), representing approximately 48% of all US physicians were reported to have received $2.4 billion in industry payments, including approximately $1.8 billion for general payments, $544 million for ownership interests, and $75 million for research payments. Compared with 47.7% of primary care physicians (205 830 of 431 819), 61.0% of surgeons (110 604 of 181 372) were reported as receiving general payments (absolute difference, 13.3%; 95% CI, 13.1-13.6; odds ratio [OR], 1.72; P < .001). Surgeons had a mean per-physician reported payment value of $6879 (95% CI, $5895-$7862) vs $2227 (95% CI, $2141-$2314) among primary care physicians (absolute difference, $4651; 95% CI, $4014-$5288). After adjusting for geographic spending region and sole proprietorship, men within each specialty had a higher odds of receiving general payments than did women: surgery, 62.5% vs 56.5% (OR, 1.28; 95% CI, 1.26-1.31); primary care, 50.9% vs 43.0% (OR, 1.38; 95% CI, 1.36-1.39); specialists, 36.3% vs 33.4% (OR, 1.15; 95% CI, 1.13-1.17); and interventionalists, 58.1% vs 40.7% (OR, 2.03; 95% CI, 1.97-2.10; P < .001 for all tests). Similarly, men reportedly received more royalty or license payments than did women: surgery, 1.2% vs 0.03% (OR, 43.20; 95% CI, 25.02-74.57); primary care, 0.02% vs 0.002% (OR, 9.34; 95% CI, 4.11-21.23); specialists, 0.08% vs 0.01% (OR, 3.67; 95% CI, 1.71-7.89); and for interventionalists, 0.13% vs 0.04% (OR, 7.98; 95% CI, 2.87-22.19; P < .001 for all tests). CONCLUSIONS AND RELEVANCE: According to data from 2015 Open Payments reports, 48% of physicians were reported to have received a total of $2.4 billion in industry-related payments, primarily general payments, with a higher likelihood and higher value of payments to physicians in surgical vs primary care specialties and to male vs female physicians.

RESUMEN

In 2013/14, Risk & Policy Analysts Ltd undertook the first global study on the socio-economic value of Manganese (Mn). Based on a top-down analysis of the key supply chains for Mn, it outlined the economic importance of Mn ore and alloys in terms of their direct and indirect economic value, as well as their effects on employment (jobs and wages). In 2013, global production of Mn ore was worth an estimated US$ 10.2-11.1 billion. Taking into account multiplier effects in the supply chain, the total economic value of Mn ore production globally in 2013 is estimated at US$ 21-23 billion. Direct employment related to Mn ore production is estimated at 44,000-78,000 people worldwide (with total wages estimated at US$ 2.7-4.6 billion per year), plus 33,000-59,000 jobs are created through indirect and induced employment effects. Meanwhile, the production of Mn alloy contributes around US$ 23 billion per year to the global economy (based on global production of around 19 million mt and 2013 market prices). In total, the value of Mn alloy production worldwide, taking into account downstream multiplier effects in the supply chain, is estimated at around US$ 146 billion per year. Direct employment related to Mn alloy production is estimated at 67,000-86,000 jobs worldwide (with total wages estimated at US$ 613-796 million per year), plus 217,000-278,000 jobs created through indirect & induced employment effects. In addition, numerous industries/sectors, products and/or applications are heavily dependent on Mn production and use. Mn is a critical raw material input and alloying element for the steel industry, for which there are no known alternatives. It can be argued that without Mn the entire steel industry (based on the current physico-chemical properties of steel) would not exist and, as a result, the value of the steel industry - an estimated US$ 964 billion to US$ 1446 billion in 2013 - is reliant on the continued supply and use of Mn. Besides its use in steel, Mn is also a critical element in the manufacture of dry cell and other batteries (notably, those used in electric vehicles) and the production of aluminium alloys (e.g. for beverage cans). Mn is also a micronutrient needed for plant growth and plays a vital role in agricultural production. It is also essential for maintaining the health and well-being of the human body and is used in food supplements and medicines. Furthermore, its use in developing applications (such as advanced steel products in automotive applications and batteries for electric vehicles) has the potential to provide socio-economic and environmental benefits in the future through enhancing vehicle safety and reducing fuel use/emissions.

RESUMEN

As suggested by UNEP, the key to sustainable development is to create a "green economy" which should encapsulate all three sectors: the industry, the people, and the government. Therefore, there is an urgent need to develop and implement the green technologies into the existing facilities, especially in the developing countries. In this study, the role of green supply chains in eco-industrial parks (EIPs) towards a green economy was investigated. The strategies and effective evaluation procedures of the green economy were proposed by assessing the barriers from the perspective of institution, regulation, technology, and finance. In addition, three case studies from iron and steel-making, paper mill and pulping, and petrochemical industries were presented and illustrated for building the green supply chains. For example, in the case of Lin-Hai Industrial Park, a total of 15 efficient green supply chains using waste-to-resources technologies were established by 2012, resulting in an economic benefit of USD 100 million per year. It suggests that the green supply chains should be established to achieve both economic growth and environmental protection. With these successful experiences, building a green supply chain within industrial park should be extensively promoted to make traditional industries around the world being environmentally bearable, economic viable, and social equitable.

RESUMEN

An acidic peroxidase was extracted from garlic (Allium sativum) and was partially purified threefold by ammonium sulphate precipitation, dialysis, and gel filtration chromatography using sephadex G-200. The specific activity of the enzyme increased from 4.89 U/mg after ammonium sulphate precipitation to 25.26 U/mg after gel filtration chromatography. The optimum temperature and pH of the enzyme were 50°C and 5.0, respectively. The Km and V max for H2O2 and o-dianisidine were 0.026 mM and 0.8 U/min, and 25 mM and 0.75 U/min, respectively. Peroxidase from garlic was effective in decolourizing Vat Yellow 2, Vat Orange 11, and Vat Black 27 better than Vat Green 9 dye. For all the parameters monitored, the decolourization was more effective at a pH range, temperature, H2O2 concentration, and enzyme concentration of 4.5-5.0, 50°C, 0.6 mM, and 0.20 U/mL, respectively. The observed properties of the enzyme together with its low cost of extraction (from local sources) show the potential of this enzyme for practical application in industrial wastewater treatment especially with hydrogen peroxide. These Vat dyes also exhibited potentials of acting as peroxidase inhibitors at alkaline pH range.

RESUMEN

Electronic consumer products such as smartphones, TV, computers, light-emitting diodes, and photovoltaic cells crucially depend on metals and metalloids. So-called "urban mining" considers them as secondary resources since they may contain precious elements at concentrations many times higher than their primary ores. Indium is of foremost interest being widely used, expensive, scarce and prone to supply risk. This study first investigated the capability of different nanofiltration membranes of extracting indium from copper-indium-gallium- selenide photovoltaic cell (CIGS) leachates under low pH conditions and low transmembrane pressure differences (<3 bar). Retentates were then subjected to a further selective liquid-liquid extraction (LLE). Even at very acidic pH indium was retained to >98% by nanofiltration, separating it from parts of the Ag, Sb, Se, and Zn present. LLE using di-(2-ethylhexyl)phosphoric acid (D2EHPA) extracted 97% of the indium from the retentates, separating it from all other elements except for Mo, Al, and Sn. Overall, 95% (2.4 g m(-2) CIGS) of the indium could be extracted to the D2EHPA phase. Simultaneously, by nanofiltration the consumption of D2EHPA was reduced by >60% due to the metal concentration in the reduced retentate volume. These results show clearly the potential for efficient scarce metal recovery from secondary resources. Furthermore, since nanofiltration was applicable at very low pH (≥ 0.6), it may be applied in hydrometallurgy typically using acidic conditions.

RESUMEN

Mushrooms are part of fungal biota characterized by wonder. They rise up from lignocellulosic wastes: yet they become so bountiful and nourishing. Mushrooms are environmentally friendly. They biosynthesize their own food from agricultural crop residues, which would otherwise cause health hazards. The extant records show the continued use of some mushrooms, e.g., Lentinus edodes, Ganoderma lucidum, and Cordyceps sinensis are now centuries old. This review presents a pyramid model for mushroom uses (industries), as food, dietary supplements (tonic), and medicine. A regular intake of mushrooms can make us healthier, fitter, and happier, and help us live longer. The sense of purpose and vision for the mushroom industries is also briefly discussed. A variety of mushrooms have been used traditionally in many different cultures for the maintenance of health and in the prevention and treatment of various diseases. A total of 126 medicinal functions are thought to be produced by medicinal mushrooms (MM) and fungi, including antitumor, immunomodulating, antioxidant, radical scavenging, cardiovascular, anti-hypercholesterolemia, antiviral, antibacterial, anti-parasitic, antifungal, detoxification, hepatoprotective, and anti-diabetic effects. Special attention is paid to mushroom polysaccharides. Many, if not all, higher Basidiomycetes mushrooms contain biologically active polysaccharides in fruit bodies, cultured mycelium, and cultured broth. The data on mushroom polysaccharides are summarized for approximately 700 species of higher Hetero- and Homobasidiomycetes. In particular, the most important for modern medicine are polysaccharides with antitumor and immunostimulating properties. Several of the mushroom polysaccharide compounds have proceeded through phase I, II, and III clinical trials and are used extensively and successfully as drugs in Asia to treat various cancers and other diseases. Mushrooms are superior sources of different types of dietary supplements (DSs) (tonics). The advantages of using mushroom-based DSs as a matter of safety (as opposed to herbal preparations) are: (1) The overwhelming majority of mushrooms used for production of DSs are cultivated commercially (and not gathered in the wild). (2) Mushrooms are easily propagated vegetatively and thus keep to one clone. The mycelium can be stored for a long time, and the genetic and biochemical consistency can be checked after a considerable time. (3) The main advantage, in our opinion, is that many mushrooms are capable of growing in the form of mycelial biomass in submerged cultures. In this review, we discuss legal and regulatory issues introducing and controlling DSs from MMs in different countries, including the United States, the European Community, Australia, New Zealand, Japan, and P.R. China, and guidelines of the World Health Organization. One of the targets of the present review is also to draw attention to many critically important unsolved problems in the future development of medicinal mushroom science in the 21st century.

RESUMEN

Because modern technology depends on reliable supplies of a wide variety of materials, and because of increasing concern about those supplies, a comprehensive methodology has been created to quantify the degree of criticality of the metals of the periodic table. In this paper, we apply this methodology to the elements of the geological copper family: Cu, As, Se, Ag, Te, and Au. These elements are technologically important, but show a substantial variation in different factors relating to their supply risk, vulnerability to supply restriction, and environmental implications. Assessments are made on corporate, national, and global levels for year 2008. Evaluations of each of the multiple indicators are presented and the results plotted in "criticality space", together with Monte Carlo simulation-derived "uncertainty cloud" estimates for each of the aggregated evaluations. For supply risk over both the medium term and long term, As is the highest risk of the six metals, with Se and Ag nearly as high. Gold has the most severe environmental implications ranking. Vulnerability to supply restriction (VSR) at the corporate level for an invented solar cell manufacturing firm shows Se, Te, and Cu as approximately equal, Cu has the highest VSR at the national level, and Cu and Au have the highest VSRs at the global level. Criticality vector magnitudes are greatest at the global level for As (and then Au and Ag) and at the national level for As and Au; at the corporate level, Se is highest with Te and Cu lower. An extension of this work, now in progress, will provide criticality estimates for several different development scenarios for the period 2010-2050.

RESUMEN

We propose a four-step strategy, based on principal component analysis and hierarchical clustering, for selecting structurally dissimilar organic substances from a list of commercial, high volume production chemicals. The selection strategy also presents alternative structures with similar characteristics, so that practical aspects of future testing can be easily addressed. The selected compounds listed in this Article are intended for further study regarding their environmental impact and as potential pollutants.

RESUMEN

An adaptation of the Drivers-Pressure-State-Impact-Response methodology is presented in this work. The differential DPSIR (DeltaDPSIR) was developed to evaluate impacts on the coastal environment and as a tool for integrated ecosystem management. The aim of the DeltaDPSIR is to provide scientifically-based information required by managers and decision-makers to evaluate previously adopted policies, as well as future response scenarios. The innovation of the present approach is to provide an explicit link between ecological and economic information related to the use and management of a coastal ecosystem within a specific timeframe. The application of DeltaDPSIR is illustrated through an analysis of developments in a Southwest European coastal lagoon between 1985 and 1995. The value of economic activities dependent on the lagoon suffered a significant reduction (ca. -60%) over that period, mainly due to a decrease in bivalve production. During that decade the pressures from the catchment area were managed (ca. 176 million Euros), mainly through the building of waste water treatment plants. Notwithstanding this, the ecosystem state worsened with respect to abnormal clam mortalities due to a parasite infection and to benthic eutrophication symptoms in specific problematic areas. The negative economic impacts during the decade were estimated between -565 and -315 million Euros, of which 9-49% represent the cost of environmental externalities. Evaluation of these past events indicates that future management actions should focus on reducing the limitation on local clam seeds, which should result in positive impacts to both the local socio-economy and biodiversity.
