    Abstract Renewable energy exploitation is among the development strategies set by the government of Rwanda on the roadmap to 2023/2024 universal electricity access and the United Nations plans by 2030. Numerous previous studies on clean energy technologies in Rwanda have mostly focused on households’ usage but there are currently no studies describing the feasibility of clean energy technologies for financial institutions. The skepticism on renewable energy in Africa was previously reported by some personnel. Having realized that most SACCOs (Savings and Credit Co-Operatives) in Rwanda use diesel technology for backup/emergency electricity supply, taking consideration of abundant solar resources in Rwanda, having… More >

    Machine Learning-Based Threatened Species Translocation Under Climate Vulnerability

    Nandhi Kesavan*, Latha

    Intelligent Automation & Soft Computing, Vol.36, No.1, pp. 327-337, 2023, DOI:10.32604/iasc.2023.030910

    Abstract Climate change is the most serious causes and has a direct impact on biodiversity. According to the world’s biodiversity conservation organization, reptile species are most affected since their biological and ecological qualities are directly linked to climate. Due to a lack of time frame in existing works, conservation adoption affects the performance of existing works. The proposed research presents a knowledge-driven Decision Support System (DSS) including the assisted translocation to adapt to future climate change to conserving from its extinction. The Dynamic approach is used to develop a knowledge-driven DSS using machine learning by applying an ecological and biological variable… More >

    CO2 and Cost-Based Optimum Design of Sustainable Metakaolin-Modified Concrete

    Xiaoyong Wang*

    Journal of Renewable Materials, Vol.10, No.9, pp. 2431-2450, 2022, DOI:10.32604/jrm.2022.020829

    Abstract Metakaolin is a highly reactive pozzolanic material that is widely utilized for enhancing the performance of concrete. This study offers a framework for the mixture design of sustainable metakaolin-modified concrete with low CO2 emissions and low costs. Different design strengths after 28 days are first formulated, with values such as 30, 40, 50, and 60 MPa. A genetic algorithm is then used to determine the optimal mixtures. Minimized CO2 and cost are set as the aims of the genetic algorithm. The strength of the concrete, its workability (slump), and carbonation service life with climate change are set as constraints of the… More >

The result showed that the climatic change in the lake basin area of Gangcha county is noticeable. The average temperature, average minimum temperature, average maximum temperature, and evaporation showed an increasing trend. But the evaporation in the study area was higher than precipitation. The average relative humidity showed a decreasing trend. And the sunshine and the… More >

    Wheat Breeding Strategies under Climate Change based on CERES-Wheat Model

    Jintao Cui1,2,*, Jihui Ding3, Sheng Deng4, Guangcheng Shao3, Weiguang Wang1,2, Xiaojun Wang5, Yesilekin Nebi6

    CMC-Computers, Materials & Continua, Vol.72, No.3, pp. 6107-6118, 2022, DOI:10.32604/cmc.2022.027611

    Abstract Climate change has inevitably had a negative impact on agricultural production and food security. Crop breeding improvement is an efficient option to adapt to future climate and increase grain production. To study the potential to provide valuable advice for breeding under climate change condition, the crop growth model was used as basis to investigate, the effects of the cultivar genotype parameters of the crop estimation through resource and environment synthesis-wheat (CERES-Wheat) model on yield under different climate scenarios. In this study, solar radiation had a positive effect on the yield of winter wheat, while the effects of daily temperature change… More >

    Phyton-International Journal of Experimental Botany, Vol.91, No.5, pp. 915-927, 2022, DOI:10.32604/phyton.2022.018688


    Under changing climate, trace elements like selenium (Se) have emerged as vital constituent of agro-ecosystems enabling crop plants to off-set the adverse effects of suboptimal growth conditions. The available form of selenium is important for boosting its bioavailability to crop plants having varied agro-botanical traits and root architectural systems. As compared to selenite, the selenate has a weaker soil bonding, higher absorption in the soil solution which results in a comparatively absorption by plant roots. Various factors including dry climate, high pH, optimal ambient air temperature, less accumulation of water, and low concentration of organic matter in the soil tend… More >

    Climate Change and Its Adverse Impacts on Plant Growth in South Asia: Current Status and Upcoming Challenges

    Mohammad Saidur Rhaman1,*, Tahjib-Ul-Arif2, Mohammad Golam Kibria3, Anamul Hoque3

    Phyton-International Journal of Experimental Botany, Vol.91, No.4, pp. 695-711, 2022, DOI:10.32604/phyton.2022.018898

    Abstract Socioeconomic development, adaptive capacity of the population, and demographic conditions across the states of South Asia make it more vulnerable to climate change. South Asia is daily going to be more vulnerable to climate change and climatic variability. This region is facing multiple challenges in terms of climate change, dilapidation of ecosystems, and food insecurity. Climate is the primary determining factor for agricultural output, which unswervingly influences food production across the globe. South Asia is mainly an agricultural foundation based region and thus the economy of these regions directly depends on agriculture and agricultural production. Due to the extensive dependence… More >

    José Carmen Soto-Correa1, Abraham Saldaña-Vega1, Víctor Hugo Cambrón-Sandoval1, Laura Concostrina-Zubiri2, Mariela Gómez-Romero3,*

    Phyton-International Journal of Experimental Botany, Vol.91, No.4, pp. 827-840, 2022, DOI:10.32604/phyton.2022.017929

    Abstract Lichens are symbiotic organisms that comprise a fungus and a photosynthetic partner wich are recognized as a good indicator of climate change. However, our understanding of how aridity affects the diversity of saxicolous lichens in drylands is still limited. To evaluate the relationship between saxicolous lichen diversity and aridity in a central México dryland, a geographical transect was established of 100 km to build an aridity gradient in the semiarid zone of the State of Querétaro, Mexico, comprising ten sampling sites with a 10 km separation. Species richness, abundance and diversity of soil lichen species were recorded using two sampling methods: the… More >

    CDLSTM: A Novel Model for Climate Change Forecasting

    Mohd Anul Haq*

    CMC-Computers, Materials & Continua, Vol.71, No.2, pp. 2363-2381, 2022, DOI:10.32604/cmc.2022.023059

    Abstract Water received in rainfall is a crucial natural resource for agriculture, the hydrological cycle, and municipal purposes. The changing rainfall pattern is an essential aspect of assessing the impact of climate change on water resources planning and management. Climate change affected the entire world, specifically India’s fragile Himalayan mountain region, which has high significance due to being a climatic indicator. The water coming from Himalayan rivers is essential for 1.4 billion people living downstream. Earlier studies either modeled temperature or rainfall for the Himalayan area; however, the combined influence of both in a long-term analysis was not performed utilizing Deep… More >

    Oxidative metabolism of photosynthetic species and the exposure to some freshwater and marine biotoxins


    BIOCELL, Vol.45, No.4, pp. 813-821, 2021, DOI:10.32604/biocell.2021.015360

    Abstract Environmental climate conditions could lead to an increasing global occurrence of microorganism blooms that synthesize toxins in the aquatic environments. These blooms could result in significantly toxic events. Responses of photosynthetic organisms to adverse environmental conditions implicate reactive oxygen species generation; but, due to the presence of a varied cellular antioxidant defense system and complex signaling networks, this oxidative stress could act as an important factor in the environmental adaptive processes. The objective of this review was to assess how some biotoxins are implicated in the generation of oxidative and nitrosative metabolic changes, not only in biotoxin-producing organisms but also… More >
