Summary: This study maps and assesses the current and future capacity of marine phanerogams in Spain to store and sequester blue carbon. The results show that a majority of carbon storage is currently managed within Natura 2000 areas, but there is a projected decline in carbon storage by 2050. The economic implications of these losses are substantial, equivalent to around 1.6% of the Spanish GDP. It is concluded that transformative management change is necessary to conserve marine phanerogams in Spain.

Summary: The study quantified and assessed the spatial dynamics of ecosystem service provision in a landscape undergoing agricultural intensification over an 85-year period. The results showed non-linear trends in ecosystem services and linear increase in economic activity, indicating the existence of potential thresholds or tipping points that need to be avoided in the future to ensure sustainable agricultural intensification. Further research into feedback mechanisms is required to fully understand the occurrence of tipping points in agricultural systems.

Summary: This study compared the Traditional Comprehensive Assessment (TCA) with Ecosystem Stability Theory (EST) and Ecosystem Regime Shift Theory (RST) using Onondaga Lake and Poyang Lake as case studies. It was found that biological oxygen demand (BOD) could be a suitable variable for calculating temporal stability and variance indexes, as well as general trends in EST and RST. This recommendation to replace TCA with BOD as a key variable is preliminary and needs to be validated with data.

Summary: Soil carbon storage is crucial for the global chemical regulation of the atmosphere, and its measurement is used to assess landscapes as carbon sinks or sources. This study developed InVEST soil carbon stock models for two agricultural landscapes in Hungary using national carbon stock data and soil sample data. The models were evaluated to determine their usefulness in land-use management and policy development. The integration of soil sample data with national carbon stock data shows potential in assessing landscape-scale soil carbon storage.

Summary: Rubber and oil palm cultivation in Southeast Asia is causing significant harm to biodiversity and natural habitats. The expansion of these crops is resulting in the destruction of forests and other croplands, with rubber plantations being converted to oil palm at an increasing rate. This slow readjustment of land use could have indirect impacts on tropical and sub-tropical environments. It is important to implement sustainable measures that address both oil palm and rubber cultivation to prevent further displacement and threats to natural habitats.

Summary: Implementation of water-saving irrigation practices in lowland rice results in increased availability of nitrate in the soil and favours germination of upland weeds. Changes in both soil nitrate concentration and weed flora may affect the competition between rice and weeds. The study aimed to evaluate the effects of nitrogen source on growth, nitrogen uptake, and competition between rice and different types of weeds. The results suggest that increased availability of nitrate in aerobic rice soils may be advantageous for the competitiveness of upland weeds, especially at high transpiration demand, but may be disadvantageous for common lowland weeds.

Summary: A study on the effect of alternate wetting and drying (AWD) in rice production in the Vietnamese Mekong Delta (VMD) showed that AWD has the potential to reduce greenhouse gas emissions and freshwater use during the dry season. However, it also led to a significant yield reduction of 7% on average across all varieties. The study highlights the importance of adapting AWD to both environmental conditions and genotype for successful implementation.

Summary: Sweet potato production in coastal areas is often affected by salinity, and salt-tolerant clones are needed to maintain production. Little is known about salt tolerance traits in sweet potato, but excessive salt stress can lead to the production of reactive oxygen species (ROS) that damage plant membranes and reduce photosynthesis and growth. Antioxidant enzymes play a role in scavenging ROS, and the activities of these enzymes can be used to identify salt-tolerant genotypes. Potassium appears to regulate leaf stress levels and the activities of antioxidant enzymes in sweet potato.

Summary: Rice production contributes significantly to Vietnam's greenhouse gas emissions. Reducing emissions by changing farming practices, such as irrigating methods, is a potential solution. This study investigated the impact of different rice varieties on methane emissions and found that varietal variation had the largest effect under continuous flooding conditions. However, alternate wetting and drying irrigation generally reduced methane emissions. These findings highlight the importance of varietal selection and irrigation methods in mitigating greenhouse gas emissions from rice production in Vietnam.
