| Abstract: | Northeast China comprises Heilongjiang, Jilin and Liaoning Provinces, with a total area of 790,000 km2 and a population of about 107 million. Northeast China, located at relatively high latitudes, (from about 39 to 53°N), is
one of the coolest regions in China with long and cold winters, a short growth season and frequent cold extreme events, which
are adverse to agricultural production. However, since the 1980s, Northeast China has experienced significant warming with
annual mean temperature rising by 1.0–2.5°C. The increase of accumulated temperature, the extension of the growth period and
the recession of summer cool disasters all contributed to improved conditions for crop growth and led to a northward movement
of the agricultural climate zone. In addition, the adaptation to warming including the adjustment of crop composition and
structure as well as the adoption of advanced technologies greatly facilitated agricultural development. As a result, total
grain production in the region increased rapidly. This paper describes in detail climate change, adaptation measures and final
agricultural outcomes, alongside with economic and political factors and the role of different political actors in Northeast
China. |
