Impacts of climate variability on the spatio-temporal dynamics of plant formations in the forest-savannah transition zone: the case of the Lamto Scientific Reserve, Central Côte d’Ivoire

/0 Comments/in /by

Understanding climatic variability’s effects on land and biodiversity is vital for guiding sustainability, conservation, and climate impact predictions in fragile ecosystems like Côte d’Ivoire’s forest-savanna transition zone. This study aims to analyse the impact of climate variability on the spatio-temporal dynamics of land use in the Lamto Scientific Reserve. To do this, a set of monthly climate data covering the period from 1990 to 2022 was used, including indicators such as rainfall, maximum, minimum and average temperatures, drought and standardised rainfall indices. The study also involved the classification of Landsat images dating from 1990, 2002, 2012 and 2022, enabling changes in land use to be observed. The corresponding areas were correlated with the climatic variables using a Spearman correlation test. The results show a transition from savannah to denser tree cover in the reserve. In addition, an increase in rainfall, varying between 900 and 1687 mm, suggests that Lamto could be classified as a humid region. The analysis highlights the complex interactions between climate change, particularly high temperatures, and land-use dynamics. Gallery and semi-deciduous forests show resilience in the face of rising temperatures, favouring their expansion. On the other hand, pre-forest formations, such as open forests and wooded savannahs, are more affected by these temperatures, which hinders their development. Tree savannahs also show a certain resilience, while shrub savannahs and bare land are often associated with ecological degradation processes in response to high temperatures. Finally, although rainfall plays a role, its influence seems minor, suggesting that other environmental or climatic factors, such as watercourses or microclimate, play a more significant role in land use/land cover dynamics.

The Nexus between Mediterranean Diet, Obesity and Climate Change

/in /by

Obesity and climate change consist of two major problems which have severe economic, environmental, social and health impacts all over the world. Mediterranean diet used to be the traditional diet in Mediterranean region with many nutritious and health benefits and low environmental impacts. However, it has been replaced nowadays with the western diet or other similar diets. The interlinkages among Med diet, obesity and climate change have been studied. The interrelation among them have been analyzed indicating their complex interdependence. Obesity and climate change are mutually interlinked while the use of Mediterranean diet can reduce the obesity rates and mitigate climate change. It has also lower environmental impacts, compared to western diets, leading to sustainable agricultural systems. Climate change has adverse impacts to Mediterranean diet due to harmful impacts on agriculture. Our findings indicate that the broad adoption of Mediterranean diet would reduce the obesity rates, mitigate climate change, reduce the undesired environmental impacts of the food production system and promote the sustainable agriculture which is necessary for the healthy nutrition of an increasing global population. The results could be useful to national and international policy makers who are trying to develop policies for the mitigation of climate change and the reduction of obesity rates promoting nutritious, healthy and sustainable food production and consumption systems.

The Interrelation between Obesity Management and Climate Change in Greece

/in /by

Two major global problems of our era are climate change and obesity. Both are interlinked and interconnected having undesired social, economic, environmental impacts as well as harmful impacts on human health. The rate of obesity and overweight in children and adults in Greece is high compared to other EU countries causing many health, social and economic problems. Climate change is foreseen to have severe and harmful impacts in Greece as well as in other Mediterranean countries altering the climate conditions. Obesity and its treatment mitigate climate change, mainly due to the change in the dietary pattern of the treated patients. The proposed diets for managing obesity, based on Mediterranean dietary patterns, have less GHG emissions and lower climate footprint. Climate change makes more difficult the treatment of obesity, mainly due to the rising temperatures. Climate change has undesired and harmful impacts on obesity treatment in Greece while obesity treatment results in the mitigation of climate change in the country. Future policies for climate change mitigation and managing obesity in Greece should take into account their mutual interconnections and interlinkages in order to maximize their effectiveness in treating these two severe pandemics in the country.

Scenario Planning for Strategic Decision-Making in Captive Power Plant: A Case Study of EBC Company Facing Global Net Zero Emission Challenges Beyond 2031

/in /by

Greenhouse gas emissions from human activities, especially the combustion of fossil fuels, increased world surface temperatures by 1.1 °C between 2011 and 2020 compared to the 1850–1900 period. In order to limit global temperature rise, and achieve net-zero emissions by mid-century, as outlined in the Paris Agreement—which Indonesia signed in 2016—a substantial decrease in coal usage is imperative. This poses uncertainties for coal-dependent companies like Eastern Borneo Coal (EBC) in Indonesia. This study investigates the business environment uncertainties faced by EBC, particularly regarding its captive coal power plants, and assesses the potential risks associated with various future scenarios using scenario planning method. Findings suggest EBC must prioritize equipment upgrades and compliance measures in stricter regulatory environments, enhance operational efficiency and diversify investments in favourable conditions, implement cost reduction strategies and focus on high-quality coal production in challenging markets, and maintain flexibility and explore export opportunities under looser regulations. Emphasizing the importance of monitoring key indicators, engaging with stakeholders, and investing in sustainable technologies, the study provides strategic insights to help EBC navigate future uncertainties and maintain competitiveness, positioning it as a leader in sustainable energy practices beyond 2031.

Impacts of Rainfall Variability on Streamflow in the Drylands of Northern Kenya: Assessing Water Availability under a Changing Climate

/in /by

Water availability is a function of climatic and land surface conditions, which determine the amount and distribution of atmospheric water as it reaches the surface. This largely depends on rainfall, whose variability affects water, food and livelihood security. This paper sought to quantify the effects of rainfall variability on water availability in an effort to support effective water resources management. Coefficient of Variation (CV), Standardized Anomaly Index (SAI) and Mann-Kendall trend test approaches were used to assess variability and trends, while correlation and regression analysis were employed to determine effects of rainfall variability on streamflow. A hydrological model, Soil and Water Assessment Tool (SWAT), was used to simulate streamflow with a view to assessing water availability under two climate change scenarios; Representative Concentration Pathways (RCP) 4.5 and 8.5. Results show that the area experiences moderate to extreme rainfall variability, as indicated by CV and SAI values that ranged from 20 to 99% and -2.5 to +3 respectively, resulting in moderate to extreme floods and droughts that often disrupt livelihoods. Current streamflow simulations (1981 – 2020) indicated increasing trends. Near and far future streamflow volumes will decrease by 15% during the April-May-June season while during October-November-December season they will increase by 13%, compared to the present. Increasing trends of rainfall and streamflow indicate that the area has opportunities for rainwater harvesting while the high variability indicates a need for early warning systems to cushion communities from climatic shocks evidenced by the impacts of climate extremes experienced in the area.

Climate change, a global issue largely caused by human activities, is now beginning to be addressed by the G20, including financial institutions. Indonesia, as part of the G20, is implementing a sustainable finance program to improve the financing, durability, and competitiveness of financial services institutions. This study evaluates the adoption of sustainable banking practices in Indonesia within the context of global climate change initiatives. Using the Banks’ Environmental, Social, Governance, and Indirect Impact (BESGI) framework, which provides a comprehensive assessment of banks’ ESG performance using the Multidimensional Synthesis of Indicators (MSI) aggregation method. The BESGI performance of 14 Indonesian banks from 2020-2022 was assessed, revealing varying results of fluctuating data with Mandiri scoring the highest in year 2021 and BTN the lowest in year 2020. The findings indicate a growing emphasis on sustainable finance within the Indonesian banking sector in terms of financing and investment. The BESGI Score has insignificant results on banks’ performance and stability. However, further research is essential to comprehend the implications of these practices on the performance and stability of banks.

Algae’s Promise to Sequester Carbon Sheds New Insight on Changing Climate

/in /by

The addition of more greenhouse gases (GHG) to the earth’s atmosphere, which accounts for more than half of the planet’s warming potential, has resulted in changes in long-term average weather conditions, or climate change. In order to counter the increased concentration of carbon dioxide in the atmosphere, carbon sequestration is a newly developed strategy. Contrary to carbon emission reduction measures, carbon sequestration has a strong potential to lower carbon dioxide levels or mask carbon dioxide emission if the gas is trapped from several stationary sources and used effectively to produce chemical and energy. The implementation of carbon regulations has spread widely.

The cost of air pollution is credited with a monetary value. Due to this, investments in the growth of microalgae for carbon sequestration have received attention from all around the world. With these systems, existing carbon mitigation strategies are shown to be a viable and promising alternative. In general, the microorganism groups that make up microalgae are extremely diverse and quick-growing, and they are very skilled in photoautotrophic, heterotrophic, and mixotrophic settings. With a unit carbon dioxide fixation capacity 10–50 times greater than terrestrial plants, these microalgae can be grown on non-fertile land. Describe in detail the most recent advancement in the effective use of microalgae for carbon dioxide in this article review.
