Urban tree inventory is a great tool for gathering data that can be used by different end users. This study attempted to chart the species diversity in planted areas and measure their tree diameter at breast height to screen them for the carbon storage potential. A total of 2860 trees belonging to 36 species were recorded in the planted vegetation in parks and avenue plantation. The dominant species were Azadirachta indicia (25.5%), Conocarpus erectus (19.2%), Ficus spp. (15.5%), Tabebuia rosea (9.2%), Peitophorum pterocarpum (9.0%) and the remaining represents (21.6%) of the tree identified in this study. It was found that the highest contribution of carbon sequestration (CO 2 equivalent) is dominated by the Ficus spp. (30.3%) with a total of 3399.3 tCO 2 eq, followed by Azadirachta indicia (25.4%) with a total of 2845.2 tCO 2 eq and Conocarpus erectus (20.4%) with a total of 2286 tCO 2 eq. The entire area has the capability to sequester around 11,213.3 tCO 2 eq and on average of 3.9 ± 0.1 tCO 2 eq. In accordance with the findings, it is imperative for the preservation of a sustainable environment to have vegetation that has the capacity to store carbon. The study suggests, there is potential to increase carbon sequestration in urban cities through plantation programs on existing and new land uses and along roads.
Capacity for agriculture production needs to be increased to meet the demands of the increasing human population. Within alternatives for an improvement in technology of agriculture in arid and sub arid countries' irrigation with magnetized water (MH 2 O). This study was carried out to investigate the nutrients taken up by plants irrigated with (MH 2 O). During this study, we have grown Cucumis sativus in greenhouse for one month. The growth was carried on a sandy loamy soil type with two sets of pots 1) one set of pots without MH 2 O, as reference and 2) another set of pots was irrigated with MH 2 O. The results revealed that the plants' leaves irrigated with MH 2 O were enriched in Zn, Cu and depleted in Ba, Ti and Sr relative to the plant grown in control conditions and unchanged in Fe, V, Ni; Mn and Cr. The roots of the same plants irrigated with MH 2 O were depleted in Fe, Mn, Ti, Ba, V, Ni, Cr, Zn and Sr. Translocation of elements from roots to leaves irrigated with MH 2 O seems more important than for plants irrigated with ordinary water. Based on the results of this study, irrigation with magnetized water may exhibit a positive effect on nutrition of plants. In addition to the effect of MH 2 O on growth, content of nutrients, revealed the effect on the quality of plants. These results show that irrigation with MH 2 O in arid countries with reduced water resources, may help to promote agriculture for an amelioration by increasing available elements.
Mangroves in coastal cities are under threat due to development pressures. However, mangrove ecosystems can serve as a potential carbon sink for mitigating the impacts of climate change. The main objective of this study was to estimate the carbon sequestration potential of mangroves in the Al-Qurm natural reserve, Muscat, Oman. The reserve was classified into three distinct zones and was estimated through field measurement and remote sensing techniques. The study found that each zone sequesters varying levels of carbon. The highest mean carbon stock was measured in the landward zone (20.2 ± 0.3 kg•C/m 2 ), followed by the middle zone (8.7 ± 0.4 kg•C/m 2 ) and seaward zone (5.8 ± 0.8 kg•C/m 2 ), respectively. The carbon sequestration rate of the sediment range was between 5.0 g C/m 2 •year -12.5 g C/m 2 •year. Normalized difference vegetation index (NDVI) derived from above-ground biomass showed a positive relationship (r = 0.73) with biomass measured in the field. However, the average above-ground carbon was underestimated (6.3 kg•C/m 2 ) than the above-ground field measurement (7.0 kg•C/m 2 ). This 0.82 km 2 of the natural reserve was estimated to sequester approximately 9512 tonnes of carbon equivalent to 0.035 Mt of CO 2 e. This highlights the importance of conserving this natural reserve, despite a growing demand for land use in and around the reserve for development needs.
