Since 2000, IOM has been producing world migration reports. This World Migration Report 2018, the ninth in the world migration report series is meant to better contribute to increase the understanding of current and strategic migration issues throughout the world.

The El Niño/Southern Oscillation (ENSO) has a pronounced influence on year-to-year variations in climate1. The response of fires to this forcing2 is complex and has not been evaluated systematically across different continents. Here we use satellite data to create a climatology of burned-area and fire-emissions responses, drawing on six El Niño and six La Niña events during 1997–2016.

 

A critical question for agricultural production and food security is how water demand for staple crops will respond to climate and carbon dioxide (CO2) changes, especially in light of the expected increases in extreme heat exposure. To quantify the trade-offs between the effects of climate and CO2 on water demand, we use a ‘sink-strength’ model of demand which relies on the vapour-pressure deficit (VPD), incident radiation and the efficiencies of canopy-radiation use and canopy transpiration; the latter two are both dependent on CO2.

Almost 14,000 archeological sites and national monuments in the United States could be lost by the year 2100 as seas rise due to climate change, scientists said on Wednesday.

To mitigate the effects of climate change, government, through the Environment ministry, is set to operationalise the ‘Tree Fund’.

Experts want to give people a chance to choose what they prefer to grow and to eat.

WALVIS BAY – A Norwegian scientist on Saturday reaffirmed the depletion of the pilchard fish species in Namibian waters after conducting a survey along the country's coastline.

Climate change is one of the biggest challenges the world must meet today and in the future. Prolonged droughts and desertification are among the issues faced by many countries, especially in Africa and Asia, where the rural poor and smallholders are most heavily affected.

Research of glacial lake outburst floods (GLOFs) – specific low frequency, high magnitude floods originating in glacial lakes, including jokulhlaups – is well justified in the context of glacier ice loss and glacial lake evolution in glacierised areas all over the world. Increasing GLOF research activities, which are documented by the increasing number of published research items, have been observed in the past few decades; however, a comprehensive insight into the GLOF research community, its global bibliometrics, geographies and trends in research is missing.

A group of “source” reefs have been identified that could form the basis of a life support system for the Great Barrier Reef, helping repair damage by bleaching, starfish and other disturbances.
