“…A growing interest on weather extremes analyses has emerged in the research community during the last two decades (Nicholls and Alexander 2007;Zwiers et al 2013;WMO and GWP 2016;Seneviratne et al 2021), leading also to the works of the Expert Team on Climate Change Detection and Indices -ETCCDI, that suggested 27 indices (Klein Tank et al 2009). Weather-related hazard analyses focused on agriculture are quite spread in scientific literature (WMO and GWP 2016;Shah et al 2021;Bacci 2017;Antle et al 2015;Sivakumar et al 2005;Groot et al 2018), particularly on drought and floods and/or on specific crops, also in Italy (Moonen et al 2002). However, other extremes need to be deeply investigated in relation to their potential impacts, such as extreme cold and hot temperatures, as well as heat waves, during sensitive crop stages (Monteleone et al 2023), also considering future scenarios of potential alterations of bioclimate and trend acceleration towards warmer and dryer conditions, as for example reported for some Mediterranean agricultural areas (coastal countries of the Adriatic Sea) (Charalampopoulos et al 2023).…”

Agriculture is highly dependent on environmental, climate and weather conditions and on extreme weather events leading to natural disasters. Such events are more and more frequent in Italy, and in the last decades huge public investments were dedicated to risk management policies in agriculture. In order to set an adequate weather-related risk assessment, a robust analysis of the hazard is needed, which requires an agro-meteorological approach to detect the potential impacts of weather extremes on agricultural activities. With the aim of assessing the effectiveness of the current risk management policy in catching the main hazards, specific agro-meteorological indices were applied to highlight occurrence, trends, and spatial patterns of extreme events. The analysis was based on reanalysis datasets and focused on a study area in Southern Italy (Campania region) during the 1981–2021 period. The findings are reported in terms of maps and statistics aggregated at administrative unit level (5 provinces) and show a general intensification of weather extremes in the last decades, both in frequency and intensity of the events. The main indications refer to growth rates of heavy precipitation, potentially leading to flood, locally exceeding 3–4 mm/year, an increasing number of months with severe/extreme droughts, mainly concentrated during the growing season. An upward trend was also observed for days with extreme maximum temperatures, which already exceeded or approached 50% between June and September in the 1981–2021 period in most areas. Maximum temperatures above 35 °C are becoming more frequent and in the inner areas they were reached in 10 days in the 2021 summer quarter. On the other hand, no significant trends were detected for late frosts. In terms of policy implications, the results seem to suggest that some extreme weather events can no longer be considered as exceptional at the present time and in a trend perspective, making them less suitable to be addressed through the risk management tools based almost exclusively on the strategy of transferring risks (insurances and more recent mutual funds) both for farmers and for the allocation of public resources. Therefore, the need is underlined for improving the design of the risk management policies to increase farms’ resilience and adaptation to climate change. Moreover, the study highlights the information potential of agro-meteorological indices in supporting evidence-based decision making in agriculture.

“…During the years 1980-1985, small dams were built at the bottom of secondary valleys to prevent salinisation [29,30]. The analysis of flood and drought episodes suggests the need to improve water management systems to reduce the risks of yield loss [31]. The local topography is relatively flat, making building reservoirs for water management difficult.…”

The anoxic conditions produced after the reflooding of acid sulphate soil (ASS) can reduce sulphate and/or Fe(III) with a consequent rise in pH. This study aimed to compare the effect of different amendments on ASS remediation and to analyse the effect on soil pH and exchangeable aluminium. Two mid-term incubation experiments were carried out to analyse the effect of amendments and water management on ASS. Soil samples were taken in the Santak Valley from four agricultural plots. During the first experiment, each soil sample was subject to two water management systems (flooded and non-flooded) and three amendment types (rice straw, manure, and lime). During the second experiment, the flooded condition was performed with three organic amendments (rice straw, manure, and biochar). In the first experiment, the amendments with organic matter (rice straw, and manure) increased the pH more under the flooded conditions, and manure was effective in reducing exchangeable aluminium (Alex) to 45% in the control soil. In the second experiment, all the organic amendments reduced soluble Al, but whereas straw increased soluble Fe, biochar diminished it. The amendment addition increased the soil pH and reduced Alex. The Alex reduction was greater for the stabler organic amendments: manure and biochar.
