Just got a paper published in Ecology and Evolution. It is basically about reindeer life history and risk sensitivity. Continue reading “Risk-sensitive reproductive allocation: fitness consequences of body mass losses in two contrasting environments”
Herskovits showed that cattle were a dominant element among East African pastoralists’ culture and life. Cattle were important in many ways, e.g. as a symbol of wealth, dowry, and in ceremonies. Continue reading “Are Nomadic Pastoralists Non-Rational?”
- Livestock is the fastest growing agricultural sector, and in some countries accounts for 80% of GDP.
- Grasslands – the basis for livestock production – cover ~70% of the global agricultural area.
- More of the land surface of the earth is used for grazing than for any other purposes.
- Pastoralism produces 10% of the world’s meat, and supports some 200 million pastoral households who raise nearly 1 billion head of camel, cattle and smaller livestock.
- >1 billion people depend on livestock, and 70% of the 880 million rural poor living on less than USD 1 per day are at least partially dependent on livestock.
In the early days, research was all about establishing typologies. So also in the study of nomadic pastoralism, which was concerned with establishing typologies of “pure pastoralists or nomads” where the units of analysis were “ideal types”.

So I just bought a scanner to scan the many pictures I have from my stay in Tibet in 2000 and 2001. While I spent most of my time in the capital, Lhasa, I have yet to get to those pictures. Consequently, I have selected a few pictures showing some aspects of the daily life of the nomads in the Aru Basin. Continue reading “Tibetan lives: Nomads in the Aru Basin”
Just got a paper published in PLOS ONE. Basically, it provides the rationale for why it pays off for pastoralists to keep large herds of livestock. Continue reading “Why Herd Size Matters – Mitigating the Effects of Livestock Crashes”
While not a particularly good quality map, it at least show the area my latest publication pertains to (Aru Basin). It is published in the journal International Journal of Sustainable Development & World Ecology.
The topic of the paper is mobility, a classic pastoral stagey for dealing with environmental variation. Mobility is used to manage resource variability, for example, during droughts where pastoralist have moved from affected areas to unaffected (or less affected) areas.
