Predicting the impact of climate change and human activities on river systems is imperative for effective management of aquatic ecosystems. Unique information can be derived that is critical to the survival of aquatic species under dynamic environmental conditions. Therefore, the response of a tropical river system under climate and land-use changes from the aspects of water temperature and dissolved oxygen concentration were evaluated.

In April 2016, southeast Asia experienced surface air temperatures (SATs) that surpassed national records, exacerbated energy consumption, disrupted agriculture and caused severe human discomfort. Here we show using observations and an ensemble of global warming simulations the combined impact of the El Niño/Southern Oscillation (ENSO) phenomenon and long-term warming on regional SAT extremes. We find a robust relationship between ENSO and southeast Asian SATs wherein virtually all April extremes occur during El Niño years.

On 23 March 2017, the British Medical Association, in partnership with the Sustainable Development Unit for the health sector in England, released Ethical procurement for health: workbook 2.0, 1 a guide and workbook for protecting labour rights in medical supply chains. This is an update to a document released 6 years earlier in response to evidence of abuse of worker rights at several factories manufacturing health-care products destined for global markets.
