In addition, change detections were calculated to identify contraction and expansion of areas, and the distributional core shift was determined to estimate the spatial movements. Results indicate that E. lineatus and S. sierra will potentially move to deeper waters away from the coastline. Alternatively, C. albus could be a species to potentially gain more importance for the fishing sector due to potential variations in climate. These results constitute a critical scientific basis for evaluating the climate change vulnerability of the fishing sector and the decision-making process in the future of small-scale fishery management in the southern Colombian Pacific Ocean.The search for the plant origin bioactive compounds is increasing over animal origin compounds. Echium oil (EO) contains high amounts of plant based omega-3 fatty acids. Moreover, curcumin addition may increase the release of these omega-3 fatty acids during digestion. The study's objective is to determine the bioaccessibility of curcumin in simulated intestinal digestion conditions and the release behavior of fatty acids of echium oil from nanoemulsions. We prepared curcumin and EO nanoemulsions with a microfluidizer using two different concentrations of surfactant, Tween 80 (5% and 10%). Emulsion stability tests, antioxidant analysis, in vitro oil release and fatty acid composition assays were conducted. Results showed that curcumin-containing nanoemulsions provide higher radical scavenging activity than the EO nanoemulsions. In addition, in vitro bioaccessibility of curcumin after in vitro simulated intestinal digestion was calculated as 35.5%. Gas chromatography results of the digested nanoemulsions revealed that curcumin addition decreases oleic acid release while increasing stearidonic acid (SDA) release.This study aimed to assess the available livestock feed resources in the Lalo kile district of Kellem Wollega Zone, Western Ethiopia, in terms of species biomass composition and dry matter yield of dominant forage species. The district was stratified into two agro-ecologies mid-altitude areas and low-altitude areas. The effects of grazing intensity on dry matter yields and biomass composition were analyzed using a randomized complete block design replicated three times having two blocks differed by two agro-ecologies (three mid-altitude kebeles and three low-altitude kebeles). The present study used seventy-two pasture samples and 20 × 20 m forage trees collected randomly from the two agro-ecologies of the study area. The General Linear Model of the SAS 19.0 version was used to compare the effects of the agro-ecology and species on dry matter yield and biomass composition. The result of the study indicated that the average dry matter yield for grasses, legumes, and other herbaceous forages was 1.156 t/ha, 0.2dation associated with poor biomass yield, low quality and variable supply of feeds between the season. Therefore, this study suggests setting up land-use regulation policy to allocate separate land for feed production and commonly use for livestock feeding to improve livestock productivity and contribute to food security and poverty alleviation of small holder farmers in the study area.Reproductive parameters of dairy animals are generally affected by meteorological factors. This study aimed to investigate the effects of heat stress (HS) on reproductive parameters Saanen and Saanen× Red Maradi (½S½RM) dairy goats reared on a private farm in a tropical sub-humid environment in Benin. To assess the reproductive performances 103 goats (46 Saanen and 57 ½S½RM) were followed up from January 2015 to December 2019. The temperature-humidity index (THI) was obtained during the same period using meteorological data such as ambient temperature (AT) and relative humidity (RH). Pearson correlation matrix analysis was then performed between the environmental variables and the reproductive parameters. Reproductive parameters of ½S½RM goats were better than those of Saanen goats. The conception (92.09%), prolificacy (156.54%) and fecundity (117.11%) rates of ½S½RM goats were significantly higher than those of Saanen goats (67.16%; 149.41% and 89.70%). The conception rate of Saanen goats was not affected by the level of THI. The conception, prolificacy, and fertility rates of ½S½RM goats decreased from 97.22%, 161.35% and 121.52%, at moderate THI to 83.89%, 148.86%, and 110.04% at extreme THI, respectively. In summary, although Saanen goats were very efficient in milk production, their reproductive performance was affected by the level of THI. On the contrary, the ½S½RM crossbred goats had a better conception, prolificacy and fertility rates in the sub-humid tropical climate of Benin.This study focused on the current situation and management after the end-of-life solar photovoltaic (PV) module in Bangladesh. The solar PV cells have a lifetime to serve properly, which is about 15-25 years from installation. Solar PV cell has recycling potentiality as well as the risk of producing hazardous wastes. After the end-of-life, the solar panel would turn into waste, specifically e-waste, which might be an environmental concern in the long run. Thus, it is crucial to estimate the waste production and to delineate the environment-friendly management. Therefore, this study aims to visualize the present status of solar PV cells, potential waste generation, and their management perspectives in Bangladesh. We also studied the existing policy of waste management. This study followed a mixed methodological approach, including the key informant interview (KIIs), synthesis of existing literature-based findings, stakeholder consultation and secondary data inventory. From the results, it was found that Bangladesh has huge potential to generate solar PV-based e-waste in the near future that needs to be tackled with high priority. A total about 33205.36 tonnes of potential e-waste can be generated from installed PV cells. A suitable management system might be able to recover materials such as glass (24,468 tonnes), aluminium (2,656.43 tonnes), silicon (1404. 92 tonnes), and copper (49.89 tonnes) from the PV cells wastes. As there is an excellent opportunity to recover resources from the waste panels, there is also scope to grow enterprise for recycling of waste panels. Unfortunately, such policy or plan from the government is yet to be taken into account. However, a long-term national plan is required to manage this waste, maintaining the high standard based on in-depth research.Due to high rice consumption, food insecurity can negatively impact health; hence, food diversification is considered an appropriate solution for achieving national food security. Artificial rice production using local natural resources will support food sustainability in Indonesia. Sago, arrowroot tuber, and mung bean flours were the main ingredients for producing artificial rice using the hot extrusion method. The effects of composite flour composition and extrusion temperatures on the nutritional value (carbohydrate, protein, fat, and fiber), morphological structure (scanning electron microscopy analysis), thermal stability (differential scanning calorimetry analysis), and acceptability of artificial rice were investigated in this study. The results showed that the best composition was obtained when using a combination of 50% (w/w) sago flour, 30% (w/w) arrowroot tuber flour, and 20% (w/w) mung bean flour. The results of chemical analysis showed that the best artificial rice in this study contained 11.18% water content, 80.27% carbohydrates, 5.14% protein, 0.46% fat, and 5.14% crude fiber. G Protein antagonist The product contained sufficient fiber and carbohydrate content to be an appropriate staple food. The best extrusion temperature was 85 °C. Moreover, the differential scanning calorimetry profiles showed that artificial rice began undergoing physical changes at approximately 100 °C. Importantly, the color, texture, aroma, and taste of the cooked artificial rice were accepted by consumers.In developing countries like Ethiopia, agriculture takes the leading role in the economy and enhancing the efficiency of agriculture resource decision making remains essential to eradicate extreme poverty through promoting sustainable agricultural production. Recent economic growth efforts in agriculture dependent economies are aggravating to further natural resource degradation, environmental pollution, and climate change. One of the main challenges is the use of inefficient conventional land use decision-making. Conventional land use decision making refers to the practice of traditional land use decision-making, which is inefficient to capture spatial and temporal land use decision dynamics and trade-offs. This paper reviewed existing literatures on decision-making models in agriculture targeting to document the potential of mathematical model-based decision making to enhance the sustainable performance of agriculture in developing countries compared to the existing conventional agricultural practice decision approach. From over 400 literatures collected from the Google Scholar search engine; 63 articles were selected for the synthesis. The literatures were screened through inclusion and exclusion criteria. Literatures that used any mathematical model as a decision support tool in agriculture and related sectors, included a clear description of the model type, aim of the study, the key attribute characterizing the application of the model, decision support system, and output were included in the review. The synthesis result uncovered that with varying degrees of impact, flexibility, and complexity, mathematical model-based land use decision making has greater potential to enhance sustainable performance of agriculture and resource use efficiency in developing countries.This study highlights the mechanisms of Pb(II)-phycoremediation using the Pb(II) tolerant strain of Scenedesmus obliquus. First, monitoring of cell growth kinetics in control and Pb(II)-doped medium revealed significant growth inhibition, while the analyses through flow cytometry and Zetasizer revealed no difference in cell viability and size. Residual weights of control and Pb(II)-loaded cells assessed by thermogravimetric analysis were 31.34% and 57.8%, respectively, indicating the uptake of Pb(II) into S. obliquus cells. Next, the use of chemical extraction to distinguish between the intracellular and extracellular uptake indicated the involvement of both biosorption (85.5%) and bioaccumulation (14.5%) mechanisms. Biosorption interaction of Pb(II) ions and the cell wall was confirmed using SEM-EDX, FTIR, zeta potential, zero-charge pH, and contact angle analyses. Besides, the biochemical characterization of control and Pb(II)-loaded cells revealed that the bioaccumulation of Pb(II) induces significant increases in the carotenoids and lipids content, while it decreases in the chlorophyll, carbohydrates, and proteins content. Finally, the metabolomic analysis indicated an increase in the relative abundance of fatty acid methyl esters, alkanes, aromatic compounds, and sterols. However, the alkenes and monounsaturated fatty acids decreased. Such metabolic adjustment may represent an adaptive strategy that prevents high Pb(II)-bioaccumulation in cellular compartments.
