Removal of heavy metals from wastewater and soil is of prime importance for a clean environment and human health. Green technology uses different types of plants to extract contaminants from the environment. This potential approach to cleaning the environment, termed phytoremediation, is emerging as a low-cost and eco-friendly treatment technology. The introduction of novel traits for the uptake and accumulation of pollutants into high biomass plants is proving a successful strategy for the development of improved phytoremediators. In this review, we describe the recently available information on using plants for treating environmental contamination. Some recent innovative technologies for improving phytoremediation are highlighted.</p> Asfa Ashraf Iqra Iqbal Muhammad Naeem Iqbal Fakhar-un-Nisa Yunus Copyright (c) 2021 PSM https://creativecommons.org/licenses/by-nc/4.0/ 2021-10-31 2021-10-31 5 2 34 40 Impact of Vocational Agricultural Training Programs on the Promotion of Date Palm Cultivation in Ghayathi, United Arab Emirates https://journals.psmpublishers.org/index.php/ijafe/article/view/582 <p>This study was performed to evaluate the perception level of the farmers and labor related to date palm cultivation. A complete list of two fifty respondents was randomly selected who have undergone capacity building programs through training and demonstration on date’s production technologies at Ghayathi city from 2017-18 to 2019-20. The data collected revealed that an overwhelming majority (98%) suggested that their working efficiency could be enhanced by offering them training courses in date palm cultivation. The highest change in perception level of 79.15% and 99.21% was observed in the method of composting and bagging and netting, respectively. Imparting training and literature to the farmers engaged with date palm cultivation by the agriculture extension department were the common suggestions presented by the respondents.</p> Imran Arshad Muhammad Umer Rabbani Zaheer Ahmed Khan Wajiha Ali Copyright (c) 2021 PSM https://creativecommons.org/licenses/by-nc/4.0/ 2021-10-31 2021-10-31 5 2 16 20 Economic and Environmental Benefits of Biogas Plant and its Impact on Women Health in Punjab Pakistan https://journals.psmpublishers.org/index.php/ijafe/article/view/583 <p>Solid fuel consumption leads to increase indoor air pollution and health burden. The study aims to quantify the impact of biogas fuel on women’s health and to conduct the economic feasibility of the biogas plant by considering environmental benefits. The study was based on primary data, collected through a well-structured questionnaire from 282 respondents by employing a multistage sampling technique. We employed the Poisson regression model cost-benefit analysis and internal rate of return (IRR). The results indicated that total time spends in the kitchen and polluted cooking sources has a positive and number of windows in the kitchen, education has a significantly negative impact on the frequency of diseases among women working in the kitchen. Biogas contributes to improving the environmental and economic wellbeing that subsequently flourishes the living standard of rural people. The benefit-cost ratio indicated that Rs. 1.2 can be generated in return by spending Rs.1 on small size biogas plants. The internal rate of return from a single small size biogas plant is 30 percent. All sizes of biogas plants can recover its cost in 4th year after the plant installation. So, we can suggest that biogas can be the finest and profitable substitute for solid fuel.</p> Muhammad Mudassar Abedullah Shahzad Kouser Copyright (c) 2021 PSM https://creativecommons.org/licenses/by-nc/4.0/ 2021-10-31 2021-10-31 5 2 21 33 Vocational Training Programs: A Step Toward Sustainable Agricultural Systems https://journals.psmpublishers.org/index.php/ijafe/article/view/585 <p>Vocational training programs aim at enhancing adoption of technological innovations in agriculture to achieve sustainable food security, reduce poverty, and stimulate employment by building human and institutional capacity. An important indicator of the impact of training program is the extent to which the farmers have adopted the practices of cultivation technology. The adoption of technologies that have the potential to contribute to sustainable farming systems can promote cultivation of plants. In this issue, Arshad et al. report that the working efficiency of farmers could be enhanced by offering them training courses in date palm cultivation. The higher cultivation of plants depends on farmers adopting the appropriate technology and management practices. The adoption of practices can be enhanced by raising farmers' general awareness and knowledge to change their perceptions and attitudes towards sustainable farming practices.</p> Muhammad Naeem Iqbal Asfa Ashraf Copyright (c) 2021 PSM https://creativecommons.org/licenses/by-nc/4.0/ 2021-10-31 2021-10-31 5 2 41 43
