中標津へ、そして東京へ【To Nakashibetsu and to Tokyo】

 I had two trips in a row within a fortnight. First, I went to the eastern side of Hokkaido Island. The trip was to the other side of the same prefecture, but it took a whole day to get there. I realized that how big Hokkaido is. The reason that I wanted to visit the eastern side of Hokkaido (Nakashibetsu) was that I wanted to see pasture based farming before winter kicks in. We still see some pasture near Sapporo city, where I live, however, the pasture management over the other side of the island was completely different from what I saw near my town.

For example, farmers in Nakashibetsu have to deal with freezing soils whereas the amount of snow they have is relatively smaller, compared to this side of the island. It was a wonderful trip and I learned a lot from one of my friends, who lives in Nakashibetsu.

After that, I had a quick rest in our home and then traveled to Tokyo, attending the 3rd International Conference on Nitrification (ICoN3) held at Chuo University. I have presented my previous work at a workshop prepared for young scientists. The scientists who attended this conference study “nitrification”. This is a process related to a nitrogen cycle and is very important in relation to any natural ecosystems. For examples, nitrification occurs in the oceans, in rivers and lakes, and in soils. This process is performed by microbes called “nitrifiers” thus there were so many microbiologists attending this conference from all over the world. 

ここ二週間ほど出張が続いています。まずは北海道の東側、中標津町への出張。同じ道内ですが、丸一日かけての移動でした。牧草ベースの農業を冬が本格的に始まってしまう前に見たい、というのが利用でした。札幌近郊でも放牧地はあるのですが、北海道のあちら側とこちら側では、放牧経営スタイルがまるっきり違うと言っても過言ではありません。

例えば、中標津の農家は土が凍ってしまうための問題に対処しなければいけませんが、札幌近郊ではそういった問題は少ないようです。こういったことについて中標津在住の友人からたくさん学ぶことが出来ました。

その後、少しだけ家に戻った後は東京へ。第三回国際硝化会議へ出席してきました。場所は中央大学。以前行った実験について短い発表を「若手」を対象としたワークショップでお話しさせていただきました。この会議では「硝化」というプロセスをテーマにしていますが、このプロセスは窒素が地球上を循環する上で非常に重要で、海や河沼、土などで起こっています。このプロセスは硝化菌という微生物によって行われていますので、世界中からたくさんの微生物学者が集っていました。
