The environmental impact of emissions appears to be increasingly important for food, particularly those of animal origin. The LCA (Life-Cycle Assessment) method, an internationally standardized method used to calculate the environmental impact of goods or services, in the carbon footprint, does not take into account the carbon set and consequently the subtraction of carbon dioxide by the plant biomass whether or not aimed at the production of food of animal origin. This methodology could overestimate the carbon dio [...]

Carnauba straw (Copernicia prunifera), residual biomass derived from wax extraction, was evaluated as a potential feedstock for bioenergy production. The characterization was carried out using elemental analysis, proximate analysis, Higher Heating Value (HHV), FTIR spectroscopy, SEM, and FRX. The carbonization, using a Muffle Furnace, was applied as a thermal conversion technique to improve the fixed carbon content, and preliminary densification was done to assess the potential for future production of briquettes.

Sasthamkotta Lake eco-region is a freshwater Ramsar site in Kerala, India. Eco-regions are ecologically and geographically defined larger land or water mass areas with a characteristic assemblage of the ecosystem and significant biodiversity. A decentralized and locally self-sustaining mechanism has been achieved in managing this eco-region by a participatory model through a joint Biodiversity Management Committee (jBMC) constitution. BMCs are custodians of the environment, and biodiversity, confined to a village/P [...]

Cyanobacteria have great potential as a platform for biofuel production because of their fast growth, ability to fix CO2 gas, and genetic tractability. They also preserve the sustainability of an ecosystem without harming the environment. High-performance biofuels made from cyanobacteria can be utilized as a base for the production of green energy. Although a lot of studies have been conducted where plants and crops are used as the source of energy, cyanobacteria have been reported to have a more efficient photosyn [...]

This review covered recent research products on fuel-briquette with emphasis on its production technologies and physical characteristics involving shapes, volumes, resiliencies, and mechanical compressive strengths; combustion properties such as high heating values, volatile matters, moisture contents, ash contents and fixed carbon; chemical analyses for the content of components such as nitrogen, hydrogen, sulfur, oxygen and carbon; emission characterization such as and economic potentials. This review provides op [...]

Recently, microplastics have emerged as a major environmental pollutant and have been documented globally. Several studies have shown that microplastics can accumulate heavy metals and persistent organic pollutants as they pass through the environment due to their functional groups interacting with and complex these substances. While conventional wastewater treatment methods can reduce a significant amount of microplastics, many still make their way into rivers and oceans worldwide from their effluents. One of the [...]

Core sediment (sapropel) samples were collected from Lake Okunozero, the Republic of Karelia, Russia, to assess the distribution of heavy metals and their main fractions, probable sources of pollution, and potential ecological and toxicological risks for the water body. Heavy metal concentrations were measured by the mass spectrometry method using an XSeries-2 ICP-MS. The sequential extraction of heavy metals from sapropel samples was performed using the scheme of Tessier. According to the Russian Interstate Standa [...]

For wind-wave interaction studies, from the literature, two criteria for the wind sea are used: one is the wave age and the other wave steepness. Analysis of pertinent datasets from a data buoy near the passage of Hurricane Matthew in 2016 indicates that CpU10 = -15 HsLp + 1.3. Here CpU10 is the wave age and HsLp is the wave steepness, where Cp is the phase speed of the peak wave, U10 is the wind speed at 10 m, Hs is the significant wave height, and Lp is the peak or dominant wave length. It is found that 87% of th [...]

This paper reviews the growing importance of satellite imagery to provide Normalized Difference Vegetative Index (NDVI) maps, relevant to environmental land management assessment, in the context of resource and climate-related conflict based upon our own humanitarian project-related support. Near real-time space-based monitoring benefits land assessment, human rights observers, and Non-Governmental Organizations (NGOs), in the presence of unstable regimes or socio-economic upheaval. Access to areas to validate clai [...]

The present article studies the policy, numbers, and costs of disaster risk management (DRM) in Mexico, a country highly exposed to climate change, due to two oceans warming up. The PEISOR methodology facilitates interrelating complex interactions and pressures between the natural and the societal system (P), where dangerous effects (E) occur in extreme events, such as floods, landslides, and drought. The impacts (I) of global warming, the pressure of historical poverty, and vulnerable regions were affected by the [...]
