“…At the RRC experimental site, elements of water balance were continuously monitored by an integrated multi-sensor system [19,20]. The values obtained for the standard, irrigated and alternately irrigated conditions were respectively 2270 mm, 1760 mm, and 680 mm [18].…”

Economic Performance of Traditional and Modern Rice Varieties under Different Water Management Systems

Italian rice production is progressively threatened by water scarcity. Some strategies have been developed to reduce water use. Nevertheless, reducing water irrigation amounts may lower paddy rice production. This publication compares the productivity and the economic performances of traditional and modern rice varieties in northern Italy using two different water management systems. The objective of this analysis is to enhance Italian rice cultivation at the economic, environmental and agronomic levels. Some positive variations of water productivity and economic water productivity were observed for the two varieties when using a lower amount of irrigation water. However, actual production costs and most water supply fees are the same for all the irrigation methods. Furthermore, the study of agronomic traits shows that during the recent years, there were no significant differences or increases of yield among varieties. Consequently, to be adopted by farmers, the irrigation costs coupled with improved rice accessions need to be optimized.

“…Dry seeded fields steadily increased until 2012. The sudden drop recorded in 2013 is a consequence of the intense precipitation events occurred during establishment (Cesari de Maria et al, ; Miniotti et al, ). In 2016, 44% of national rice paddy fields were dry seeded.…”

“…Rice represents the most profitable cultivation in Northern Italy, but it also has the largest impact in terms of fertilizer and pesticides' use (Bechini & Castoldi, ). It is mostly grown in the upper Po Valley (see Figure ), especially in Piedmont and Lombardy regions, under controlled field flooding (Cesari de Maria et al, ). These regions alone (with about 120,000 ha and 100,000 ha of harvested fields) contributed to the 52% and 41% of the total Italian production in 2016, respectively.…”

“…Over the last 20 years, dry‐seeding has been continuously developed and increasingly adopted in Italy (Ente Nazionale Risi, ; Ranghetti et al, ; Ranghetti, Cardarelli, Boschetti, Busetto, & Fasola, ). Compared with the traditional water seeding practice, dry‐seeding in Northern Italy does not reduce yields (Miniotti et al, ), whereas it reduces the irrigation demand of about the 20% (Cesari de Maria et al, ) and the global warming potential of 56% with respect to continuously flooded rice paddy fields (as the reduction of methane outbalances the increase of nitrogen oxide emissions, Peyron et al, ).…”

Adaptation and sustainability of water management for rice agriculture in temperate regions: The Italian case‐study

et al. 2019

View full text Add to dashboard Cite

We review, analyse, and discuss the recent evolution and the future sustainability of rice paddy fields in Italy-the largest European producer-using outcomes from available literature and new analysis of agricultural statistics from local authorities, landuse and surface temperature data from remote sensing, hydrological and climate data from observations, and numerical models. We show that Italy can be considered a good representative for rice cultivation in temperate regions that are not freshwater-limited. However, this situation is changing. We report strong evidence linking the largest European reduction of seasonal surface water that have gradually occurred since 2000 over the rice cultivation area of Northern Italy, to the change in paddy management from traditional continuous flooding to a less greenhousegases-emitting practice, that is, dry-seeding with postponed flooding. This change was accompanied by several improvements in agro-practices and crop varieties. Concurrently, regional climate rapidly shifted towards sunnier weather conditions that partly contributed to higher rice yields and stability, decoupling yields from interannual climate variability, but also reducing water availability. In Northern Italy, a complete shift of rice cultivation towards dry-seeding is not compatible with seasonal water availability, and a number of drawbacks, with respect to the traditional wet seeding, are also identified from literature review. Therefore, in the context of near-term climate change, sustainable rice cultivation in the middle latitudes seems achievable (without limiting production and/or increasing volatility) by balancing traditional and dry-seeding.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Irrigated rice fields deliver the majority of rice production. Irrigated rice fields (hereafter referred to as rice fields, unless stated otherwise) provide a higher productivity compared to that of rain-fed rice fields (Grisp 2013, Cesari De Maria et al, 2017. Irrigated rice fields contribute to around 55% and 75% of global harvested rice areas and rice production, respectively (Dobermann and Fairhurst 2000, Bouman et al, 2007a).…”
