How trade chokepoints pose a growing threat to global food security

Introduction to the article: 
Trade chokepoints – maritime, coastal and inland – pose an underexplored and growing risk to global food security, argues the report Chokepoints and Vulnerabilities in Global Food Trade.

Maritime chokepoints will become increasingly integral to meeting global food supply as population growth, shifting dietary preferences, bioenergy expansion and slowing improvements in crop yields drive up demand for imported grain.

Rising trade volumes, increasing dependence on imports among food-deficit countries, underinvestment, weak governance, climate change and emerging disruptive hazards together make chokepoint disruptions – both small-scale and large-scale – increasingly likely.

Climate change will have a compounding effect on chokepoint risk, increasing the probability of both isolated and multiple concurrent weather-induced disturbances.

Investment in infrastructure lags demands growth: critical networks in major crop-producing regions are weak and aging, and extra capacity is urgently needed.

MdP – MAPS: Die Einzugs- bzw. Entwässerungsgebiete der Flüsse in Europa – ich mag diese Karte

Einzugs- bzw. Entwässerungsgebiete (Begriff aus der Hydrogeographie): 
Das durch Wasserscheiden begrenzte Gebiet, welches durch einen Fluss mit allen seinen Nebenflüssen entwässert wird. Es wird zwischen dem oberirdischen und dem unterirdischen Einzugsgebiet unterschieden.

Wonderful Map: 1.2 million Streams and 8,000 Catchment Areas

The HD map above shows the approximately 8,000 catchment areas of Europe’s 1.2 million streams and rivers. It’s based on the Strahler Stream Order Classification System. The higher the stream order, the thicker the line. I really like this map.

The 10 Longest Rivers in Europe are:

  1. Volga – 3,692km
  2. Danube – 2,860km
  3. Ural – 2,428km
  4. Dnieper – 2,290km
  5. Don – 1,950km
  6. Pechora – 1,809km
  7. Kama – 1,805km
  8. Northern Dvina–Vychegda – 1,774km
  9. Oka – 1,500km
  10. Belaya – 1,430km
