As a measure of freezing tolerance, we used the daily mean and/or the daily maximum air temperature, averaged over 10 days, before the daily minimum air temperature dropped below freezing point during early winter. For the vegetable crop, we assumed a freezing temperature of - 3 ° C or - 5 ° C. The 30-year temperature records from 15 AMeDAS observatories of the Japan Meteorological Agency were used. Of these, 13 are located in the Sanriku coastal region and two in the inland area of Iwate Prefecture. The calculated 10-day averages across the coastal sites were comparable to or larger than those of the inland sites. They showed a speciﬁc increase in the coastal zone ranging from Kuji to Yamada. The larger values resulted from relatively low minimum and high maximum temperatures, which are speciﬁc to that region. It is generally thought that coastal areas are suitable for the production of winter vegetable crops due to their moderate temperature regime. However, our results indicate that unlike the other typical coastal areas, the temperature regime of the Sanriku region is not moderate; therefore, it possibly increases the risk of crop freezing injury. キーワード：","PeriodicalId":112005,"journal":{"name":"Climate in Biosphere","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123132998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of these changes to the apple cultivation at present and in the future is reviewed. Due to the temperature increase, the date of flowering will advance at the rate 0.2 days year until 2040, as is observed already at present. The advancement will continue until 2100 under RCP8.5 scenario, while it will slow down after 2040 and stop around 2080 under RCP4.5 scenario. Because the varietal difference in the flowering date will gradually increase, the insect pollination may become difficult at the end of this century. Harvesting date will advance and delay in earlyand late-maturing varieties, respectively. Thus in late-maturing varieties, fruit weight may increase depending on the extension of fruit growth period. On the contrary, fruit storability will very likely reduce, and pigmentation will get worse especially in red-skin early-maturing varieties. Moreover, the risk of sunburn damage will increase, and the risk of late frost injury is also indicated to increase by several researchers. On the other hand, we can expect the reduction of snow damage because the amount of snowfall is generally predicted to decrease in the future, although such decreasing tendency is not detected in the past 50-100 years. Considering the conspicuous midday depression of photosynthesis observed in apple trees, they are now in serious sink-limited condition possibly due to the severe fruit thinning. Therefore, the fruit yield cultivated under high CO2 concentration will hardly increase, unless we alter the strength of thinning to improve the sink capacity of the tree.","PeriodicalId":112005,"journal":{"name":"Climate in Biosphere","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125521884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, based on market statistics, we investigated the assumption that the production allocation of major open-field vegetables is climatically optimized. Then, we prepared prediction models for cultivation periods, based on cultivation samples. We also elucidated the characteristics of cultivation methods, by region and season; and the ranges of preferred cultivation temperatures, by vegetable type and growing stage. In addition, by optimizing the allocation of major open-field vegetables for climate conditions (using deviations from the ranges of preferred cultivation temperatures as indicators), we identified the production situations for in-season major open-field vegetables, for 10-day periods, by former municipality (based on the Agriculture and Forestry Census), based on production and market statistics. The deviations were calculated by subtracting the limits of preferred cultivation temperature ranges from the meteorological environments of given cultivation periods (back-calculated from the arrival date based on market statistics and cultivation period prediction models). Based on a static optimization algorithm, optimized production situations were identified by repeatedly selecting, as optimal solutions, the allocations with the smallest margins, from all possible land resource allocations. Although there are still issues to be resolved, the identified production situations were consistent with the available data, and can be considered sufficiently valid.","PeriodicalId":112005,"journal":{"name":"Climate in Biosphere","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123839781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used a large collection of rice quality dataset from the Crop Survey database provided ad hoc by the Ministry of Agriculture, Forestry and Fisheries of Japan. Firstly, we conducted statistical analysis to determine the interrelationships among the various indices of rice quality such as the percentages of the ﬁrst-grade rice, undamaged rice and chalky grain, then also analyzed their relationships with surface meteorological elements and their composite indices. The results showed that the indices of rice qualities were well correlated with a heat stress index HD_m26, that is a cumulative deviation of daily averaged surface air temperature from a base of 26 ° C during the 20days after heading. Especially, the percentage of chalky grain was better explained in relation with the HD_m26 than that of simple 20 days-averaged air temperature during the corresponding period. In addition, the Quantile Regression analysis was applied to regress the percentage of chalky grain based on the HD_m26. Although the result showed the signiﬁcant linear, quadratic and cubic curves regression in each percentile values of the chalky grain with the zone of HD_m26 values, varietal differences were perceived in these statistical relationships.","PeriodicalId":112005,"journal":{"name":"Climate in Biosphere","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122229663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(2020), which identified the production situation of major open-field vegetables (in season), by former municipality (based on the Agriculture and Forestry Census), over a roughly 10-day period. Compared to the period from 1981 to 2000, the yearly mean temperature in Japan will be 0.5 to 1.5 ° C higher from 2026 to 2045, and 0.8 to 2.7 ° C higher from 2046 to 2065, based on the Model for Interdisciplinary Research on Climate Version Five (MIROC5) RCP 8.5. As temperatures rise, cultivation and harvest periods are typically shortened. Therefore, if the beginning of planting season remains unchanged, times and quantities of market arrival of the vegetables will be significantly altered. Winter harvesting periods will begin earlier, and become more concentrated. Total harvest area will increase between November and December, decrease between February and March, and experience decreases during the transitions between hot and cool season production periods. Planting frequency during cultivation periods can dramatically impact the total harvested area, with planting frequency being inversely correlated with impact. Thus far, cooperation has enabled production areas to successfully adapt to seasonal climate changes; however, these efforts are unlikely to remain successful in the face of future temperature increases due to global warming. In the near future, it is improbable that the daily mean temperature on average over 20-year periods in Japan will significantly exceed the preferred range for cultivation. However, annual temperature ﬂuctuation is already significant (in Japan, the annual ﬂuctuation of monthly mean temperatures from 1981 and 2000 was 1.0 to 1.4 ° C [RMS value]), and its impact may exceed that of global warming; therefore, careful attention must be paid to such ﬂuctuation.","PeriodicalId":112005,"journal":{"name":"Climate in Biosphere","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121147666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
