Constant Cremer is de eerste zwarte voetballer in Nederland. Hij is geboren in Belgisch Congo. Hij speelde bij Willem II in het seizoen 1904 -1905 en werd met Willem II Brabvants kampioen. Constant werd, als een donkere mulat een held in Tilburg. Hij kwam uiteindelijk terecht in Nederland Indie en werkte daar aanvankelijk in de suikerindustrie. Later werd hij directeru van een jongensweeshuis.

We investigate hydrology during a past climate slightly warmer than the present: the last interglacial (LIG). With daily output of preindustrial and LIG simulations from eight new climate models we force hydrological model PCR‐GLOBWB and in turn hydrodynamic model CaMa‐Flood. Compared to preindustrial, annual mean LIG runoff, discharge, and 100‐yr flood volume are considerably larger in the Northern Hemisphere, by 14%, 25%, and 82%, respectively. Anomalies are negative in the Southern Hemisphere. In some boreal regions, LIG runoff and discharge are lower despite higher precipitation, due to the higher temperatures and evaporation. LIG discharge is much higher for the Niger, Congo, Nile, Ganges, Irrawaddy, and Pearl and lower for the Mississippi, Saint Lawrence, Amazon, Paraná, Orange, Zambesi, Danube, and Ob. Discharge is seasonally postponed in tropical rivers affected by monsoon changes. Results agree with published proxies on the sign of discharge anomaly in 15 of 23 sites where comparison is possible.

From the article: "The term Internet of Things (IoT) is used for situations where one or more devices are connected to a network or possibly the Internet. Most studies focus on the possibilities that arise when a device is capable to share its data with other devices or humans. In this study, the focus is on the device itself and what kind of possibilities an Internet connection gives to the device and its owner or user. Also the data the device needs to participate in a smart way in the IoT are part of this study. Agent technology is the enabling technology for the ideas introduced here. A proof of concept is given, where some concepts proposed in the paper are put into practice."

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science.

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate.

The COVID-19 global pandemic has raised once more the spectre of world governance, demonstrating in one fell swoop, the intricate entanglement of nation-states and the challenges they face when confronted with a global threat. The pandemic has produced an array of problems, from the deaths of millions, the desecration of health care systems all over the world, to the disruption of the economic and social lives of most of the worlds citizens and the emergence of vaccine politics. While not addressing the pandemic directly, this dossier examines the pandemic moment as both an opportunity and a crisis for the UN and the idea of global governance. The articles in this dossier, drawn from a selection of established academics and younger scholars, highlight the expanding array of issues and challenges the UN faces as its competencies increase in the face of multiplying threats to the global system. The organisation has gained new areas of expertise, consolidated its competencies in some areas while expanding its agency in others. In addressing global challenges, the UN has increased its relevance, normative power and connection to humanity but at the same time its lacklustre performance on a lot of issues has revealed that leadership is lacking, and the organisation has in many cases been found wanting. This dossier examines some of the new challenges facing the UN with a view towards assessing the ability of the organisation to effectively respond to global crises, and whether or not it has the capacity for institutional learning and adaptation in the face of adversity and anarchy.

Studenten en bedrijfsleven roepen het hoger onderwijs op duurzaamheid prominent in het curriculum op te nemen. Dit artikel is een verkenning van de raakvlakken tussen economie en duurzaamheid met als doel thema’s te benoemen die in het curriculum van de opleidingen bedrijfseconomie en accountancy aan bod zouden kunnen komen. Er wordt eerst stilgestaan bij een beschrijving van de op ons afkomende problemen zoals klimaatverandering, grondstoffenschaarste en verlies aan biodiversiteit. Vervolgens wordt geschetst voor welke uitdagingen het bedrijfsleven staat en worden ontwikkelingen geschetst op macro-, meso- en microniveau. Afsluitend volgen suggesties voor op te nemen thema’s in het curriculum van de bedrijfseconomische en accountancy opleiding, zoals bijvoorbeeld een verdieping in de bestudering van verdelingsmechanismen (markt versus overheid), verbreding van het kostenbegrip, strategisch risicomanagement dat rekening houdt met duurzaamheid, duurzaamheidsverslaggeving en ketenmanagement. Het tot stand brengen van een duurzame economie vraagt daarnaast om buiten bestaande denkkaders te treden.

It was a landmark speech. On May 26, Angola’s president apologized and asked forgiveness for mass executions that occurred in 1977. He also announced the returning of victims’ remains to their families and the issuance of death certificates. But what does this mean for Angola’s wider reconciliation process? Other key demands and large groups of victims have still been left out, warn scholars Maarten van Munster and Joris van Wijk.

Lake Kivu is experiencing unprecedented decline in production of Tanganyika Sardine (Limnothrissa miodon). This study sought to characterise the value chain of this fish species so as to chart its sustainable utilisation. The study performed in 2015 found two chains; an informal chain that takes 30% of the production and a formal chain that handles 70%. The average catch of sardine was 30 kg/day in the high production season and <15 kg/day in the low season. Two thirds of the fishers were not aware of the governing law. Fishing malpractices included fishing in prohibited sites, beach seining and fishing during moratorium period. Majority of fishers were not satisfied with the price offered in the market as costs involved in fishing was 701 Rwanda Francs/kg caught. This is despite the shift in time since the study was performed. Therefore, there is need for re-training of value chain actors, increasinglake surveillance, strengthening internal controls of the Fishers’ Cooperatives and improving information sharing and communication among value chain actors.
