&nbsp;&nbsp;The respective awareness of the Intergovernmental Panel on Climate Change (IPCC), the Japanese government, media and citizens about the change of sea level at some future date due to climate change was surveyed and analyzed. Three official reports from the IPCC, the white paper on the Quality of the Environment in Japan from the government, the articles in the Asahi Shimbun newspaper from about the past 20 years, and the questionnaires by the Japanese and local governments conducted towards citizens were used. The results of this investigation were that the IPCC concluded in their past three reports that the sea level was estimated to be lower because of ice in the polar regions due to climate change, the Japanese government did not describe this point clearly, the newspaper drew the opposite conclusion from the IPCC and the understanding of citizens was that the change in climate caused the sea level to rise. These differences were due to the lack of or misunderstanding of scientific knowledge such as Archimedes's Principle and the migration of fluid materials, and to the psychological trend of human beings. It is necessary for the government and media to clearly explain and announce these scientific facts in a modern society which maintains a close relationship to science.<br>

外部環境の変化の激しい現代において,農業経営の多角化には追加所得確保,リスク分散,範囲の経済による資源活用など多様な役割が期待される。特に,消費地との近接性を活かした事業多角化が盛んな都市近郊農業において,多角化を通じた経営発展のメカニズムの解明が求められる。本稿では,農業経営の長期的な多角化プロセスの類型を理論化した上で,各類型における多角化と経営発展の相互関係について関東都市近郊の18 件の農業経営の事例分析より明らかにする。その際,多角化との関連性の大きな経営内部環境(アントレプレナーシップ及び経営資源)をあわせて把握した。分析の結果,農業経営の事業多角化は高度多角化型,事業補完型及び基幹事業探索型に類型化され,各類型の中でも経営内部環境の整った経営のみが経営発展(量的拡大及び質的変化)を達成していた。さらに,高度多角化型及び基幹事業探索型では多角化と経営内部環境が相互に影響しながら経営発展している一方で,事業補完型では多角化が経営発展に与える影響は限定的だった。本稿の結果は,多角化した農業経営の支援を考える際に,各経営における多角化の位置づけ及び経営発展のボトルネックを明確にすることの重要性を示唆している。In a drastically changing external environment, farm diversification serves several purposes, including additional income generation, risk reduction, and efficient resource utilization. In peri-urban agriculture, where structural diversification is widespread, the mechanism of farm development through diversification deserves attention. This study aims to demonstrate the interaction between farm development and each type of theoretically defined diversification using data from 18 farms located in urban areas in the Kanto region, Japan. The internal farm environment factors like entrepreneurship and management resources affect farm diversification. Consequently, farm structural diversification can be classified into four categories: highly diversified type, complementary enterprise type, search and selection type, and non-diversified type. The study identifies that farms of each category whose management exhibit factors like entrepreneurship, management skills, and active social networks, achieve farm development. Furthermore, in farms that were of the highly diversified type, and the search & selection type had an interaction between diversification and internal farm environment, the diversification of farms of the complementary enterprise type had little impact on its management. These findings have significant implications on policies supporting diversified farms. Research is required to identify the types of farm diversification and associated challenges for further growth.
