A group of 24 Hawke's Bay hill country farmers are working with service providers to improve the resilience of their farming systems. An important step in the process was to undertake an inventory of their risk management strategies. Farmers were interviewed about their farming systems and risk management strategies and the data was analysed using descriptive statistics. There was considerable variation in the strategies adopted by the farmers to cope with a dryland environment. Importantly, these strategies had to cope with three types of drought and also upside risk (better than expected conditions), and so flexibility was critical. Infra-structure was important in managing a dryland environment. Farmers chose between increased scale (increasing farm size) and geographic dispersion (owning a second property in another location) through to intensification (investing in subdivision, drainage, capital fertiliser, new pasture species). The study identified that there may be scope for further investment in infra-structural elements such as drainage, deeper rooting alternative pasture species and water harvesting, along with improved management of subterranean clover to improve flexibility. Many of the farmers used forage crops and idling capacity (reduced stocking rate) to improve flexibility; others argued that maintaining pasture quality and managing upside risk was a better strategy in a dryland environment. Supplementary feed was an important strategy for some farmers, but its use was limited by contour and machinery constraints. A surprisingly large proportion of farmers run breeding cows, a policy that is much less flexible than trading stock. However, several farmers had improved their flexibility by running a high proportion of trading cattle and buffer mobs of ewe hoggets and trade lambs. To manage market risk, the majority of farmers are selling a large proportion of their lambs prime. Similarly, cattle are either sold prime or store onto the grass market when prices are at a premium. However, market risk associated with the purchase of supplements and grazing was poorly managed.

The article is devoted to the analysis of inaccuracies in the terminology and in the description of safety management procedures associated with both shortcomings in the documents of the International Civil Aviation Organization (ICAO) and incorrect, and sometimes simply erroneous translation of certain provisions of the documents from English into Russian. As well known, all ICAO documents are originally written in English and correct translation is extremely important for their adequate understanding and application in practice. This is especially important for Russian airlines, as methodological developments on the implementation of safety management systems (SMS) at the state level are not enough. Experience in the development and implementation of SMS in airlines shows that due to inaccuracies in ICAO documents there are additional difficulties. Accordingly, there is a broad and often subjective interpretation of a number of ICAO Rube provisions in airlines, which leads to a conflict of priorities and irrational use of resources of airline and other aviation enterprises. The article notes with a demonstration of specific examples that in each new ICAO document in Russian the names of components and elements of the conceptual framework (structure) of the SMS of the service provider change, although in the original English version these names are constant since 2006.The main methodological difficulties in the development and implementation of the SMS by service providers are associated with risk management, and it is in this part that the greatest number of inaccuracies in the documents is observed. It is shown, in particular, that the term "Risk Factor" appeared in the ICAO SMM due to the erroneous translation into Russian of the English term "Safety Risk", and its use in parallel with the term "Hazard" in high-level documents (the Air Code of the Russian Federation, article 24.1 and in the Decree of the Russian Federation Government from 18.11.2014 No 1215) introduces additional confusion at the level of air enterprises in the understanding of risk management within the technocratic concept of risk.

Climate changes are changing intentions of farmers to tackle climate variations in various ways. Information and Communication Technologies are proving to assist farmers to manage agricultural risk timely and with fewer efforts. Intention of farmers to use ICTs in the context of agricultural risk management is important to understand. Therefore, the present study was designed to examine intention of the farmers from the context of Malaysia. The field survey of three selected states was conducted in which 350 farmers were chosen through multi stage cluster sampling technique. The Likert scale items measuring 1 as strongly disagree to 5 as strongly agree were used in the research instrument to assess intention of the respondents. The findings revealed that the farmers showed positive intention to use ICTs for agricultural risk management from the future lens. The overall level of intention was also high. However, internet speed, small screen display and battery issues could halt intention of the farmers to harness potential of digital technologies as reported by the farmers. Thus, the study recommends that agricultural extension service providers are required to introduce various digital skill development programs for the farmers exclusively resource poor and less digital familiar farmers to reduce the risk in the agricultural sector stem from climate changes.
