Landscape Dynamics and the Impact on Ecosystem Services Value Provided by Coastal Wetlands: An Update| Chapter 6 | Novel Perspectives of Geography, Environment and Earth Sciences Vol. 4

 This study determined the dynamics of land cover changes and the mixed ecosystem services (ES) profit of coastal wetlands in northwestern Mexico. Wetlands are environments sensitive to changes in land use, moving the supply and quality of the ES they offer, and are currently in danger due to the revolutions promoted by financial activities (e.g. travel, agriculture, growing plants in liquid) to stimulate territorial development. Remote sensing methods were used to estimate change trends middle from two points 2000 and 2010, using the advantage transfer method for the economic appraisal of ES and Markov chains to model probable sketches for the years 2020, 2030 and 2050. Findings told that the ES total value flow for the period 2000-2010 fed to increase (18 million greenbacks (2007 USD)), with growing estimates of high global worth land covers, although regionally they are of low profit, as marsh/unconsolidated bottom, which raised in the estimated region during the study ending. The most notable transition probability was noticed among the unrefined wetlands, highlighting the beach and the saltmarsh (unconsolidated bottom), as the classes with the highest chance of change over time. The pertaining to the south region of the study district is the most susceptible to change, place unconsolidated bottoms and mangroves (forested saltmarsh) noticeable.

Advanced Study on Soil Quality Response to Long-Term Nutrients and Management Practice to Potato Production in Ultisols of Subtropical China | Chapter 5 |International Research in Environment, Geography and Earth Science Vol. 8

The creation of a sustainable agricultural system necessitates an understanding of soil quality, the degree and effect of degradation processes, and the existing land use management strategy. Soil response to management and inputs are important factors that are based on soil quality, and this study looked at Ultisols in subtropical China. Long-term studies in Asia have shown that over-exploitation of soils has resulted in the exhaustion of intensive agricultural production systems, with gradually decreasing productivity. From 2000 to 2009, improvements in soil quality were calculated using acceptable indicators in a long-term experiment at the Taoyuan Station in Hunan Province, China. The data was analysed using the SAS statistical package for ANOVA, and the means were separated using DNMRT and graphically matched to establish threshold limits for a minimum threshold data collection. The soils responded favourably with the Sweet potato-rape/NP+straw treatment (7.18 g kg-1) contributing significantly (P0.05) higher total carbon, while the Sweet potato-rape/nil fertiliser and Fallow/nil fertiliser application treatments contributed the least total carbon. Sweet potato-rape/NP+ straw contributed the most total nitrogen (0.882 g kg-1) and was slightly (P0.05) higher than the other treatments. The sweet potato-rape/NPK+stalk treatment created substantially more biomass carbon (132.66 mg kg-1) than the other treatments, suggesting that it is a stronger biomass carbon contributor. Sweet potato-rape/NPK+stalk added 23.96 mg kg-1 of biomass nitrogen to the Ultisols, which was substantially higher than Sweet potato-rape/NPK (18.34 mg kg-1), Sweet potato-rape/nil fertiliser (16.36 mg kg-1) or Fallow/nil fertiliser (14.92 mgkg-1). In contrast to Sweet potato-rape/NPK, treatments with stalk amendments resulted in increases of 3.6 to 5.7 percent biomass carbon and 15.8 to 23.5 percent biomass nitrogen. Organic matter inputs as complement fertiliser materials were blamed for increasing trends in biomass carbon, nitrogen, and phosphorus in the Ultisols. In the Ultisols, the study found that the Sweet potato-rape/NP+straw treatment (7.18 g kg-1) contributed significantly more total carbon than the other treatments (P0.05), followed by Peanut-broadbean/NP+straw (6.81 g kg-1) that contributed significantly more total carbon than the other treatments (P0.05), and the least total carbon was contributed by Sweet potato-rape/nil fertiliser and Fallow/nil fertiliser application treatments. Potato yields have declined by as much as 65.57 percent since 2007, necessitating further study to determine the cause of the decline and avoid possible yield depressions. To improve future soil quality monitoring in support of sustainable crop production and national food security, threshold limits for a selected minimum data set for the subtropical China area Ultisols on sweet potato production were established.
