Land-use management for sustainable rice production and carbon sequestration in reclaimed coastal tideland soils of South Korea: a review

Transcriptional Changes in the Developing Rice Seeds Under Salt Stress Suggest Targets for Manipulating Seed Quality

“…Global sea-level rise, which is an effect of climate change, has continued to occur throughout the entire 20th century, and is currently ongoing, resulting in saltwater intrusion ( Walthall et al, 2012 ; Mimura, 2013 ). The RLs, corresponding to 11.7% of the total arable land and 22.1% of that used for rice production in Korea face a crisis of sea-level rise, which directly causes an increase in salt concentrations ( Mimura, 2013 ; Lim et al, 2020 ). As reported by Cheong et al (1995) , topsoil samples of some selected RLs in the western coastal areas of Korea contain significantly higher levels of minerals, including Na, K, and Mg, than those of NLs, apart from the Ca levels, which are higher in topsoils of NL, as shown in Table 1 .…”

“…Around 80,000 hectares on the Gulf Coast in the United States are utilized for rice production; however, because of long-term subsidence, saltwater has intruded into rice production areas ( Walthall et al, 2012 ). In the Republic of Korea (Korea), 81 reclaimed lands (RLs) were prepared mostly in southern and western coastal areas, comprising a total area of 186,639 hectares, corresponding to 11.7% of the total arable land and 22.1% of the land used for rice production ( Lim et al, 2020 ). RLs in Korea, although critically important for rice production, are extremely vulnerable to sea-level rise and its accompanying increase in salt concentration because compared to normal land (NL), they already contain a significantly higher salt concentration and are located near the sea ( Walthall et al, 2012 ; Lim et al, 2020 ).…”

Accordingly, RLs are highly effective test sites for determining the effect of sea-level rise on rice cultivation and seed harvest.…”

Soil carbon and nitrogen dynamics by land use and management changes in East and Southeast Asian countries (soil C and N by LUMC)

“…Many East and Southeast Asian countries have long coastal areas, parts of which are used for rice production. Lim et al's (2020) review of LUMC for sustainable rice production and C sequestration in reclaimed coastal tideland soils in South Korea should be a valuable reference for other Asian countries.…”
