“…This suggests that earthworm indices can effectively reflect the impact of human management practices, land use types, soil physicochemical properties, and other factors on soil quality, thus indirectly responding to the degree of soil degradation. Similar results were obtained by Masin, Rodriguez, Zalazar, and Godoy (2020), who reported that the degree of soil disturbance caused by human activities can be estimated by measuring earthworm biomass, diversity, and ecotype distribution in different habitats in Santa Fe, Argentina. Bartz et al (2013) investigated the range of variation in earthworm density (ind m −2 ) and species numbers in no‐till systems and defined a classification of earthworm indices for different soil qualities as follows: excellent (>200 ind m −2 and >6 species); good (100–200 ind m −2 and 4–5 species); moderate (25–100 ind m −2 and 2–3 species); and poor (<25 ind m −2 and 1 species).…”

Soil degradation restricts the development of agriculture, and the degree of soil degradation is related to land use type, and efficient evaluation methods are helpful for the timely implementation of remedial measures to ensure soil sustainability. Earthworms are directly affected by the deterioration of soil properties during the degradation process. The feasibility of using earthworms to assess soil degradation, however, still needs to be verified. In our Loess Plateau study, earthworm biomass, density, and diversity (Shannon-Wiener, species richness, and Pielou's evenness) were investigated under nine different land use types (natural woodland, shrubland and grassland; planted woodland, shrubland and grassland; and cropland, orchard, abandoned land) and we analyzed their relationships with soil degradation. Our results showed earthworm biomass, density, and diversity associated with a low degree of degradation were significantly higher than those associated with a high degree of degradation. Earthworms can comprehensively characterize the physicochemical properties and biological characteristics of soils under different land use types. Linear correlations showed a significant relationship between the soil degradation index and the earthworm indices, indicating that the latter could be used to effectively evaluate and represent the degree of degradation of soils on the Loess Plateau over a certain degradation range. Nevertheless, this evaluation method requires further validation before wider use.

“…They play a vital role in renewing the soil, and can only be found in soil with specific characteristics such as texture, sufficient moisture, appropriate acidity levels, and specific nutrients (KALE; KARMEGAM, 2010). Environmental degradation resulting from human activities can directly affect the quality of soil, and pose a threat to the biodiversity of living organisms (MASIN et al, 2020). According to some researchers, soil organisms that respond to changes in the environment are considered to be of great importance in maintaining soil quality, where non-vertebrate animals form the highest biomass in the soil (MIGLANI; BISHT, 2019;LUAN et al, 2020).…”

This study was conducted to determine the effects of earthworm breeding O. cyanieum for 7, 14, 21, and 28 days in soil treated with concentrations of 800, 1000, 1500, and 2000 mg kg-1 of balanced NPK compound fertilizer and balanced NPK nano-compound fertilizer at concentrations of 30, 60, 120, and 240 mg kg-1, in addition to the control treatment. It was found that the weight and relative growth rate of earthworms decreased with increasing concentrations of fertilizers. The highest significant decrease in weight (0.257 g) and relative growth rate (40.34%) was observed at a concentration of 1500 mg kg-1 of balanced NPK compound fertilizer. Meanwhile, the highest decrease in worm weight (0.225 g) and relative growth rate (86.31%) was observed at a concentration of 240 mg kg-1 of balanced NPK nano-compound fertilizer. Fertilizers also affected the protein content in the earthworms, which differed significantly from the control treatment for both fertilizers. In addition, the fertilizers affect the histological structure of the body, with clear disruption in the epithelium of the body, layers of circular and longitudinal muscle, the lining of the intestine, especially the typhlosole. Keywords: chemical fertilizer; nano fertilizer; earthworm vitality. Efeito do fertilizante npk balanceado e nanocomposto na vitalidade da minhoca octolasion cyanieum e seu efeito na composição histológica do meio do corpo RESUMO: Este estudo foi conduzido para determinar os efeitos da criação de minhocas O. cyanieum por 7, 14, 21 e 28 dias em solo tratado com concentrações de 800, 1000, 1500 e 2000 mg kg-1 de solo de fertilizante composto NPK balanceado (20-20-20) e fertilizante nanocomposto NPK balanceado (20-20-20) nas concentrações de 30, 60, 120 e 240 mg kg-1 de solo, além do tratamento testemunha. O estudo mostrou que os fertilizantes químicos tiveram impacto sobre a vitalidade dessas minhocas, pois o peso e a taxa de crescimento relativo das minhocas diminuíram com o aumento das concentrações de fertilizantes. A maior queda significativa no peso (0,257 g) e na taxa de crescimento relativo (40,34%) foi observada na concentração de 1500 mg kg-1 de solo do fertilizante composto NPK balanceado. Já a maior redução no peso (0,225 g) e na taxa de crescimento relativo (86,31%) da minhoca foi observada na concentração de 240 mg kg-1 de solo do fertilizante nanocomposto NPK balanceado. Além disso, os tratamentos acima tiveram impacto no teor de proteína dos corpos das minhocas, que diferiu significativamente do tratamento controle, para ambos os tipos de fertilizantes. O estudo mostrou o impacto do fertilizante nas estruturas dos tecidos das minhocas, com clara ruptura na camada da pele e nas camadas musculares circulares e longitudinais abaixo dela, bem como um claro efeito no revestimento intestinal, especialmente o tiflosole. Palavras-chave: fertilizante químico; nano fertilizante; vitalidade da minhoca.

“…These changes were forced by the huge and increasing demand on natural resources caused by population growth, as well as rising income level. The enormous disturbance of environmental systems, such as climate change [6,7], land 2 of 16 degradation [8,9], water depletion [10,11], loss of biodiversity [12,13], and so on, spurred by substantial land-use change has attracted ongoing domestic and international concern.…”

Characteristics of Land Use Change in China before and after 2000

et al. 2022

China, with notable population blooming and economic development in the last decades, has experienced profound land-use changes, which, in turn, dramatically impacted the regional, even global and environment system. However, characteristics of land-use changes in China have not yet been well addressed, especially around the year 2000 when a series of land policies were put forward, such as the project of “returning farmland to forest”. To fill this gap, this paper investigated the temporal and spatial patterns of land use changes in China for the period from 1987 to 2010, by taking advantage of the continually updated China Land Use Database developed from remote sensing images. The land-use dynamic matrix, zonal model, and transition matrix were employed to characterize land-use change patterns for four time intervals (1987–1995, 1995–2000, 2000–2005, and 2005–2010) on the dimensions of conversion and modification. Results showed that land-use change affected 4 × 105 km2 (4.5%) of the total landscape in China for more than the past twenty years. Of the six land-use types, built-up land experienced the largest net increase by almost 30% (52,434 km2), with the rate of expansion accelerating after 1995. The area of cropland increased before 2000 and declined afterwards, ending with a net increase in 14,280 km2, approximately 1% of its original area. The loss in the eastern coastal region is attributed mainly to built-up land expansion, while the gain in northern China, with the price of grassland and woodland shrinking, reshaped the cropland distribution in China. The area of woodland decreased slightly by 7880 km2 without a clear pattern over time. The modification of woodland indicated an intensive forest management in terms of planting fast-growing trees in the south of China. Grassland continues to shrink at a decreasing rate, and the modification of grassland shows a tendency of transformation from sparse grassland into a dense one in the 21st century. Trade-offs among demands on food security, economic development, and environment protection forced and shaped the contemporary land-use change in China. These results contribute to understanding the trends and causes of land use change in China, which could provide underpinning knowledge for assessing environmental change, and provide insights on future land planning.
