摘要

气候变化可能会影响印度主要奶牛品种--缪拉水牛的生产和繁殖功能。因此，本研究编制了基于温度湿度指数（THI）的每周气候服务模块，并通过 WhatsApp、短信和移动应用程序向印度西北部哈里亚纳邦实验村的农民传播。研究采用了 "差分法"（DiD）这一准实验性研究设计来研究气候服务对农场经营决策和经济效益的影响。研究结果表明，气候服务对采用在动物饲料中使用油饼、矿物质和饲料添加剂等做法的农民人数有积极影响。研究发现，在短信组、WhatsApp 组和移动应用程序组，气候服务对油饼（0.39、0.45 和 0.51 千克/动物/天）、夏季精料（0.48、0.56 和 0.59 千克/动物/天）和冬季精料（0.35、0.40 和 0.42 千克/动物/天）以及矿物质混合物（9.47、12.34 和 13.08 克/动物/天）的使用量有显著影响。研究还发现，短信组、WhatsApp 组和 MobileApp 组的气候服务对夏季产奶量等经济成果指标的处理效果也很显著（分别为 0.38、0.44 和 0.50 升/只）。总体而言，气候服务的效益成本比为 1:1.8。因此，为穆拉水牛养殖户开发的专属气候服务被认为是一种有效的适应机制，可帮助脆弱的奶牛养殖业适应当今和未来的气候。

Impact of temperature humidity index-based climate services for Murrah buffaloes of India on operational decision-making and economic outcome of the farm

Climate change is likely to affect both the productive and reproductive functions of Murrah buffaloes, the major milch breed of India. Hence, in the present study, weekly modules of Temperature Humidity Index (THI) based climate services were prepared and disseminated to the farmers of experimental villages of Haryana, a state of North-Western part of India through either WhatsApp, Text SMS, and Mobile Application. Difference-in-Difference (DiD), a quasi-experimental research design was used to study the impact of climate services on operational decision-making as well as the economic outcome of the farm. The findings of the study revealed that the climate services had a positive effect on the number of farmers adopting the practices like use of oil cakes, minerals, and feed additives in the animal diet. Treatment effect was found to be significant on quantity of oilcake (0.39, 0.45 and 0.51 kg/animal/day); concentrates during both summer (0.48, 0.56, 0.59 kg/animal/day) and in winter (0.35, 0.40 and 0.42 kg/animal/day); and mineral mixture (9.47, 12.34 and 13.08 gm/animal/day) in Text SMS, WhatsApp and MobileApp group, respectively. The treatment effect of climate services on economic outcome indicators such as summer milk yield was also found to be significant (0.38, 0.44, and 0.50 L/animal) from Text SMS, WhatsApp, and MobileApp, respectively. Overall, the benefit-to-cost ratio of climate services was found to be 1:1.8. Hence, the exclusive climate services developed for Murrah buffalo farmers were found to be an effective adaptive mechanism for helping vulnerable dairy farming to adapt to the climate of today and of the future.

期刊介绍： The journal Climate Services publishes research with a focus on science-based and user-specific climate information underpinning climate services, ultimately to assist society to adapt to climate change. Climate Services brings science and practice closer together. The journal addresses both researchers in the field of climate service research, and stakeholders and practitioners interested in or already applying climate services. It serves as a means of communication, dialogue and exchange between researchers and stakeholders. Climate services pioneers novel research areas that directly refer to how climate information can be applied in methodologies and tools for adaptation to climate change. It publishes best practice examples, case studies as well as theories, methods and data analysis with a clear connection to climate services. The focus of the published work is often multi-disciplinary, case-specific, tailored to specific sectors and strongly application-oriented. To offer a suitable outlet for such studies, Climate Services journal introduced a new section in the research article type. The research article contains a classical scientific part as well as a section with easily understandable practical implications for policy makers and practitioners. The journal''s focus is on the use and usability of climate information for adaptation purposes underpinning climate services.
