藏族有上百年可持续地管理自然环境的历史。如果不是外界影响，那么究竟发生了什么，让环境退化的如此明显？ （相比文中提到的变化，气候变化的影响的历史更短。）

对许多已经城市化的半游牧民族来说，“恩人们”不会给他们选择，围栏和造林项目甚至让他们的可持续性的生活方式显得可笑。大家都知道这些外来干涉不会就此打住。这同时反映了外来者的傲慢，无论初衷善否。

Tibetans have for centuries managed their natural environment sustainably. What has changed to cause their environment to so clearly degrade if not external influence? (The impact of climate change is more recent than the changes mentioned in the article.)

Many of the semi-nomadic people who have now been urbanised will have been given little choice by their "benefactors", not to forget that fencing and aforestation projects make their otherwise sustainable lifestyles untenable. That this external interference would be unsatisfactory is just common sense. It also reflects the arrogance of outsiders - whether well-intentioned or not.

近年来，青海省游牧社区的安置项目甚为普遍（负面意义的），搬迁过程遇到了许多问题。游牧民族被赶出他们的土地，被安置进城镇或城郊的小房间里。他们失去了过往生活的方式，面临全新的挑战。大部分的牧民都不会说汉语，因此被迫迁离土地之后，他们基本上无事可做，完全没有就业的机会。并且没有足够的土地来蓄养牲畜，以至于不得不全部销售出去。关于出售牲畜的后果，请看看这则视频，它谈到了政府安置游牧民族的政策 http://sites.asiasociety.org/chinagreen/origins-of-rivers-omens-of-a-crisis/

Resettlement projects in nomadic communities in Qinghai province is very popular(in a negitive way) these years and there are many problems in the relocated nomadic communities. Nomads were kicked out from their land and arranged in small rooms/spaces in towns and urban areas, and they lost their way of live and encountering a new chanllenge. Most of the nomads are iliterate in Chinese language and thus when they kicked out from their land, they have almost nothing to do. No job opportunities at all. And they dont have enough land to keep their livestock and they have to sell them. What will if they sell their livestock? please watch this video, it talks about government policies over nomads relocation. http://sites.asiasociety.org/chinagreen/origins-of-rivers-omens-of-a-crisis/#comments

给草原植树行不通！我刚刚从文中提到的区域附近的省回来。中国需要的是历时百年的重建计划。树木作为C3从土壤中吸收碳。我们需要沿海C4植物，建立土壤碳/元素，以及蒸腾关系，才能有效的输送降雨。少数民族在青海有上千年经营草原牧业的历史，把他们驱赶出去无疑是个错误。

我已经在这些地区装置了C4槽和土壤碳。Robert Vincin （见谷歌）

Setting out a trees for grass land will fail! I have just returned for Provinces close to the region. What is needed is 100yr plan. Trees are C3 taking carbon from soil.We need to deliver rain by planting from coast C4 vegetation to build soil carbon/elements and the transpiration links. Removing the nomadic people who managed the grass/dung for 1,000yrs like those in Qinghai a mistake.
I have planted out C4 sinks in these areas and soil carbon follows. (no computer translation please) Robert Vincin (see Google)
