Fractional Differential

Soil salinization is one of the most serious environmental issues in arid and semiarid area with severe social, economic, and ecological problems. At present, most inversion models are based on raw reflectance spectra or integer differential transform. In this study, we measured the hyperspectral reflectance and EC1:5 of soil samples collected form Ebinur Lake to analyze the influence of fractional differential on correlation coefficient between EC1:5 and reflectance spectra. The results showed that the fractional differential increased sensibly the accuracy for the analysis of the reflectance spectra. The study might provide a new insight for monitoring soil salinity using hyperspectral data, and further researches should be concentrated on physical meaning of fractional differential in hyperspectral data to provide theoretical basis to building, describing, and spreading inversion models.

New Perspective

As the level of potassium can interfere with the normal circulation process of biosphere materials, the available potassium is an important index to measure the ability of soil to supply potassium to crops. There are rarely studies on the inversion of available potassium content using ground hyperspectral remote sensing and Landsat 8 multispectral satellite data. Pretreatment of saline soil field hyperspectral data based on fractional differential has rarely been reported, and the corresponding relationship between spectrum and available potassium content has not yet been reported. Because traditional integer-order differential preprocessing methods ignore important spectral information at fractional-order, it is easy to reduce the accuracy of inversion model. This paper explores spectral preprocessing effect based on Grünwald–Letnikov fractional differential (order interval is 0.2) between zero-order and second-order. Field spectra of saline soil were collected in Fukang City of Xinjiang. The maximum absolute of correlation coefficient between ground hyperspectral reflectance and available potassium content for five mathematical transformations appears in the fractional-order. We also studied the tendency of correlation coefficient under different fractional-order based on seven bands corresponding to the Landsat 8 image. We found that fractional derivative can significantly improve the correlation, and the maximum absolute of correlation coefficient under five spectral transformations is in Band 2, which is 0.715766 for the band at 467 nm. This study deeply mined the potential information of spectra and made up for the gap of fractional differential for field hyperspectral data, providing a new perspective for field hyperspectral technology to monitor the content of soil available potassium.

<p>The period of environmentalism heightened environmental concern and subsequently the emergence of Environmental Education that is anchored on awareness. It is thought that increase in environmental awareness will reverse the misuse of the environment and its resources. Four decades after the international call for Environmental Education, Earth’s degradation is far from abating as it’s pristinity is consistently and irreversibly being eroded by no less than from anthropocentric activities. Humans have seen themselves as the dominant species that is apart and not part of the organisms that constitute the environment. The philosophical value free nature concepts and the theological assumption that human are the ultimate species together with the rise of capitalism and its surrogates consumerism together conspire to diminuate environmental health. To protect the environment therefore, we must refocus EE to change human’s view of the environment and attitude towards the utilization of its resources. Environmental education can become more effective in creating respect for the environment. This paper examined the failure of efforts at addressing environmental issues via environmental education. The paper posits that environmental problems are on the increase due to lack of deliberate responsibility and stewardship, lack of a unique EE curricula and ineffective pedagogy. We suggest therefore that EE can target human perception and attitude and direct then towards biocentric stewardship for the environment. This can be achieved through a deliberate pedagogy of environmental values that promotes sustainable attitude and respect for the environment. Humans must bear the burden of responsibility to ensure the wellbeing of the environment. We must replace the philosophical value free nature concepts that nature is a common commodity and the theological assumption that humans are the ultimate species. We must also rethink our consumerism nature and the endless faith in the efficacy of technology to solve reoccurrence human induced ecological problems. These issues must be embedded in the school curriculum. Pedagogical approach to EE should essentially be the experiential model. The school curriculum must be the carrier and doer of these values that are crucial to the sustainability of the environment. Environmental ethics, environmental code of conduct, environmental nationalism, nature as manifestation of God, ascetic consumerism are recommended as key component of environmental curricula and pedagogy.<strong> </strong></p>

The satellite data obtained from various airborne as well as space-borne Hyperspectral sensors, often termed as imaging spectrometers, have great potential to map the mineral abundant regions. Narrow contiguous bands with high spectral resolution of imaging spectrometers provide continuous reflectance spectra for different Earth surface materials. Detailed analysis of resultant reflectance spectra, derived through processing of hyperspectral data, helps in identification of minerals on the basis of their reflectance characteristics. EO-1 Hyperion sensor contains 196 unique channels out of 242 bands (L1R product) covering 0.4&amp;ndash;2.5&amp;thinsp;μm range has also been proved significant in the field of spaceborne mineral potential mapping. <br><br> Present study involves the processing of EO-1 Hyperion image to extract the mineral end members for a part of a gold prospect region. Mineral map has been generated using spectral angle mapper (SAM) method of image classification while spectral matching has been done using spectral analyst tool in ENVI. Resultant end members found in this study belong to the group of minerals constituting the rocks serving as host for the gold mineralisation in the study area.

Article endeavors to analyze the prophetic guiding principles regarding human behaviors related to plants and trees being an important component of our environment. The discussion mainly deals with the key environmental issues emphasizing plantation and its significance for balancing the equilibrium of the environment. Additionally, it thrashes out that humans are urged to seedling the plantation even the world is to be ended in Islam. The present study is delimited to the present ecological crises faced by society and a great challenge to the globe. The current ecological problems i.e global warming and climate change are interpreted just to analyze the environmental behaviors in Hadith literature. However, a profundity descriptive study has been conducted in the most influential way to examine the prophetic rules for human behaviors related to trees and plants being environment friendly. Furthermore, the existing practices of humans related to such an environmental sphere also been aptly figure out to highlight all possible ways in the light of prophetic guidance to deal with prevailing environmental issues. Inconsistency between religious teachings and human behaviors need the keen interest of religious scholars and social scientists to carefully harmonize both for maintaining the ecological balance in nature.

The Belt And Road

China’s Belt and Road Initiative (BRI) is the largest infrastructure scheme in our lifetime, bringing unprecedented geopolitical and economic shifts far larger than previous rising powers. Concerns about its environmental impacts are legitimate and threaten to thwart China’s ambitions, especially since there is little precedent for analysing and planning for environmental impacts of massive infrastructure development at the scale of BRI. In this paper, we review infrastructure development under BRI to characterise the nature and types of environmental impacts and demonstrate how social, economic and political factors can shape these impacts. We first address the ambiguity around how BRI is defined. Then we describe our interdisciplinary framework for considering the nature of its environmental impacts, showing how impacts interact and aggregate across multiple spatiotemporal scales creating cumulative impacts. We also propose a typology of BRI infrastructure, and describe how economic and socio-political drivers influence BRI infrastructure and the nature of its environmental impacts. Increasingly, environmental policies associated with BRI are being designed and implemented, although there are concerns about how these will translate effectively into practice. Planning and addressing environmental issues associated with the BRI is immensely complex and multi-scaled. Understanding BRI and its environment impacts is the first step for China and countries along the routes to ensure the assumed positive socio-economic impacts associated with BRI are sustainable.
