| 1 | Index-based assessment of agricultural drought in a semi-arid region of Inner Mongolia, China显示文摘Agricultural drought is a type of natural disaster that seriously impacts food security.Because the relationships among short-term rainfall,soil moisture,and crop growth are complex,accurate identification of a drought situation is difficult.In this study,using a conceptual model based on the relationship between water deficit and crop yield reduction,we evaluated the drought process in a typical rainfed agricultural region,Hailar county in Inner Mongolia autonomous region,China.To quantify drought,we used the precipitation-based Standardized Precipitation Index(SPI),the soil moisture-based Crop Moisture Index(CMI),as well as the Normalized Difference Vegetation Index(NDVI).Correlation analysis was conducted to examine the relationships between dekad-scale drought indices during the growing season(May–September)and final yield,according to data collection from 2000 to 2010.The results show that crop yield has positive relationships with CMI from mid-June to mid-July and with the NDVI anomaly throughout July,but no correlation with SPI.Further analysis of the relationship between the two drought indices shows that the NDVI anomaly responds to CMI with a lag of 1 dekad,particularly in July.To examine the feasibility of employing these indices for monitoring the drought process at a dekad time scale,a detailed drought assessment was carried out for selected drought years.The results confirm that the soil moisture-based vegetation indices in the late vegetative to early reproductive growth stages can be used to detect agricultural drought in the study area.Therefore,the framework of the conceptual model developed for drought monitoring can be employed to support drought mitigation in the rainfed agricultural region of Northern China. | Rui LI Atsushi TSUNEKAWA Mitsuru TSUBO | 2014 | Journal of Arid Land2014，6，1： | 8 |
| 2 | Dynamics and hotspots of soil erosion and management scenarios of the Central Rift Valley of Ethiopia显示文摘大多数在埃塞俄比亚的中央裂缝山谷的低地干旱或半干旱并且在降级,与干旱的经常的出现。土壤侵蚀走水路在雨季期间是在这个区域的一个严重问题,导致为水身体的衰退农业生产,减少的食物安全,和沉积风险。然而,没有这个问题或可能的管理答案的系统的学习。满足这需要,我们分析了侵蚀从 1973 ~ 2006 评估的土壤,识别侵蚀热点,和建议可能的土壤保存情形。我们用通用土壤损失方程和地理信息系统软件估计了土壤损失 dynamicity,就在下列三个时期的陆地使用变化而言:1973, 1985 和 2006。我们以识别热点的侵蚀严厉,地形学,和陆地使用描绘了分水岭并且求婚,当模特儿,并且评估了各种各样的分水岭管理情形减轻这个问题。分别地,土壤侵蚀由于植被降级并且特别地从 1973 ~ 2006 显著地增加了,与在 1973, 1985,和 2006 的 31, 38,和 56 t ha1 的年度率几千公顷进农田的森林或树林的变换。观察土壤侵蚀率远离这个国家的土壤损失的可容忍的率并且因此要求迫切土壤保存干预,特别在热点区域。我们建议为减少的八种情形玷污损失并且评估了他们的有效性。恢复降级的土地(使用的 exclosures 和种的植被) 和在农田的安装石头侵蚀控制结构(石头东亚各国之堤岸) 分别地在 12.6% 和 63.8% 减少了全部的土壤损失。由综合管理(侵蚀控制结构和 exclosures ) 与超过 20 t ha1 的年度土壤损失对待热点区域是最有效的途径,减少在 87.8% 的土壤损失。 | Derege Tsegaye MESHESHA Atsushi TSUNEKAWA Mitsuru TSUBO Nigussie HAREGEWEYN | 2012 | International Journal of Sediment Research2012，27，1： | 6 |

| 10 | Effect of Polyacrylamide integrated with other soil amendments on runoff and soil loss:Case study from northwest Ethiopia显示文摘Anionic polyacrylamide(PAM)has the potential to reduce soil erosion through soil conditioning.However,a comprehensive study about its effectiveness especially when applied combined with other amendments have rarely been conducted in the tropical highland climatic conditions,such as in Ethiopia.The study assessed the effectiveness of PAM(P=40 kg ha^(-1))alone or integrated with other soil amendments such as gypsum(G=5 t ha^(-1)),lime(L=4 t ha^(-1))and biochar(B=8 t ha^(-1))on runoff and soil loss at Aba Gerima watershed in the Upper Blue Nile basin,northwest of Ethiopia,where there is high erosion-caused soil degradation.A total of 79 daily runoff and sediment data were collected from eight runoff plots(1.3m×4m)with three replications planted with teff(Eragrostis tef)crop for two years(2018&2019)rainy seasons.Associated changes in soil physicochemical properties and crop growth parameters were investigated.Treatments reduced seasonal runoff by 12–39%and soil loss by 13–53%.The highest reduction in runoff was observed from P+B and PAM treatments while the highest reduction in soil loss was observed from that of P+L and PAM treatments.Integrating PAM with other amendments improved soil structural stability,moisture content,soil pH(P+L)and organic matter(P+B),leading to favorable environment for crop growth(biomass yield)and reduced runoff and soil erosion.Unlike PAM,biochar and lime amendments may need more time after application to be more effective.Hence continuing the field experiment and studying physico-chemical mechanisms for extended period will better elucidate their single or combined effectiveness over time. | Birhanu Kebede Atsushi Tsunekawa Nigussie Haregeweyn Mitsuru Tsubo Temesgen Mulualem Amrakh I.Mamedov Derege Tsegaye Meshesha Enyew Adgo Ayele Almaw Fenta Kindiye Ebabu Tsugiyuki Masunaga | 2022 | International Soil and Water Conservation Research2022，10，3： | 1 |
