International Journal of Environment and Climate Change <p style="text-align: justify;">A sustainable world is one in which human needs are met equitably without sacrificing the ability of future generations to meet their needs and without harm to the environment and ecosystem function and service. Meeting this formidable challenge requires a substantial effort under climate change impact, economic development and population growth. <strong>International Journal of Environment and Climate Change (ISSN:&nbsp;2581-8627)</strong> aims to publish original research articles, review articles and short communications. This is a quality controlled, double blind peer-reviewed, open access INTERNATIONAL journal. It has long been recognized that the long-term viability of natural capital is critical for many areas of human endeavour under climate change impact. The aims are to support engineering science research with the goal of promoting sustainable development with environmentally benign engineered systems that support human well-being and that are also compatible with sustaining natural (environmental) systems.</p> SCIENCEDOMAIN international en-US International Journal of Environment and Climate Change 2581-8627 Refurbishment of Environmental Damage and Socio-Economic Consciousness Relate to Improvement of Climate Change <p>Demand for energy, water, food and shelter for raising the standard of lifestyle of country people is the driving force of democracy in modern days but that cause the environmental damages through Green House Gas, micro-particles emission from combustion of fossil fuels like coal, oil as well as fuel gases and incessant emissions of hydrocarbons from automobiles, oil fields, oil refineries besides industrial activities in the globe along with horizontal land encroachment decreasing greeneries in the planet earth with the decrease of oxygen/nitrogen ratio. The emissions are the main causes for increase in environmental pollution and responsible for climate change in contrast to the idea expressed by various researchers about the impact of climate change on environment. Mechanisms on interaction of solar/electro- magnetic radiation with PM<sub>1-2.5 </sub>and hydrocarbons in air play a role on degradation of stratospheric ozone as well as accumulation of ozone in troposphere which manifests in various episodes and global warming. Increasing population, increasing urbanization with growing carbon footprint, deceasing greeneries in the planet, the carbon-dioxide: oxygen: Nitrogen ratios in the atmosphere suffered for the last 1000 years or more. The initiatives that are needed to promote the environmental capacity through replacement of fossil fuel energy by green energy establishments, socital up-liftment through intercontinental sweet relations instead of power supremacy depriving 80% global population to refurbish the health of environment with improvement of climate. The fruit of green energy to reach all classes of people in this earth is the immediate need of the globe. The flaws of environmental laws are to be tightened and socio-environmental economic culture is to be inculcated among citizens of states for environmental health improvement vis-a-vis control on climate change to save the planet from extinction of dominant human lives.</p> Hari Sadhan Sarkar Oly Sarkar Ghosh ##submission.copyrightStatement## 2020-06-16 2020-06-16 1 25 10.9734/ijecc/2020/v10i830214 Climate Change Responses of Cocoa Farmers in Ghana <p><strong>Background: </strong>Undoubtedly, vulnerability and adaptation of the agricultural sector to the adverse impacts of climate change are among the most crucial concerns of many developing countries where agriculture is largely rain-fed. In Ghana, the cocoa sector is the mainstay of the agricultural sector, contributing about 60% of agricultural GDP. The cacao tree is susceptible to the vagaries of climate, a fact which manifests in outbreak of pests and diseases and their pattern, loss of pods and early ripening of young pods, among others. Cocoa farmers have over the years used short-term (coping) strategies and long-term (adaptation) strategies to offset the effects of climate change on their production.</p> <p><strong>Methods: </strong>A field survey of 444 cocoa farmers in Ghana was conducted, using a guided interview schedule.</p> <p><strong>Results: </strong>Farmers’ coping strategies included those on crop, soil fertility and soil water management practices. Adaptation strategies included behavioural adjustments (spraying, fertilizer application, weed control, pruning) as well as institutional and technological adjustments (change in variety and increased extension services).</p> <p><strong>Conclusion: </strong>The study showed that farmers who perceived that the climate had changed and had some effect on their production usually employed adaptation measures. Differences in farmers in terms of personal managerial and entrepreneurial capacities and family circumstances influence their responses to climate change. However, one major challenge is to separate the adaptations in response to climate change from adaptations in response to other stimuli, such as market price or government policy changes that farmers face in the real world. Assessing adaptation strategies also provides the information needed by cocoa farmers to increase their capacity to moderate potential damages and to take advantage of opportunities, if any, to survive in a changing climate.</p> David Nii Baah Buxton ##submission.copyrightStatement## 2020-06-16 2020-06-16 26 35 10.9734/ijecc/2020/v10i830215 Effect of Municipal Solid Waste Open Dumping on Soil, Water, Crop, Human Health and Its Prospectives <p>Characterization of heavy metals in 5 Km<sup>2</sup> range of dumping yard in relation to soil, water and crop has been studied. The concentration of Cd (4.05 mg/kg) in soil was higher than the permissible limit of WHO (3 mg/kg) and in descending order of metals in soil was found to be Fe&gt; Cr&gt;Cd&gt;Ni&gt;Zn&gt;Cu&gt;Pb and in bore well water it was Cr, Fe, Pb, Cd, Zn and Cu (23.20, 0.63, 0.31, 1.19 and 0.69 mg/l respectively) than the permissible limit (0.54, 0.40, 0.068, 0.03, 0.22, 0.018 mg/l) and their respective concentration ordered as Fe&gt;Zn&gt;Cu&gt;Pb&gt;Cd&gt;Ni&gt;Cr. Further the vegetables grown nearby dumping yard was highly contaminated by Cr in range (2.78 to 12.78 mgkg<sup>-1</sup>) in tomato, beans and cabbage and even in ragi and green gram Cr was high (1.78 to 14.96 mgkg<sup>-1</sup>). i.e., in Tomato; Cd&gt;Fe&gt;Cr&gt;Zn&gt;Pb&gt;Ni&gt;Cu, Beans; Cr&gt;Cd&gt;Pb&gt;Fe&gt;Zn&gt;Cu&gt;Ni, Cabbage; Cr&gt;Cd&gt;Pb&gt;Fe&gt;Zn&gt;Cu&gt;Ni, Ragi; Fe and Zn were below permissible limit and Pb, Ni, Cu, Cd are BDL and Green gram; Cr&gt;Fe&gt;Zn&gt;Pb&gt;Cu &gt; Ni&gt;Cd. In support of results, primary survey was conducted in nearby 20 villages circumventing the dumping yard. A total of 150 respondents were randomly enquired to know their level of knowledge and health status as result of open dumping site. The results revealed that 43.33%, 36% and 20.67% as medium, high and low impact in relation to heath and knowledge aspect of dumping site. Thus there is a considerable impact on environment and humans due to the presence of heavy metal in crop, soil and water.</p> S. C. Kiran C. Nagarajaiah M. Mahadeva Murthy P. C.

However, amidst plenty, food insecurity and incessant crisis ravage the government efforts to sustainable agricultural and economic development. This paper discusses the nexus between Climate vagaries and skirmish leading to shift in crop yields. It assesses grain yield variation, problems and prospect across the local governments in Taraba State. Apart from personal observation and focus group discussion, the paper relied mainly on secondary data that were generated through the analysis of relevant data from government and non-governmental agencies. Rainfall and agronomic data were collected from Upper Benue River Basin and Ministry of Taraba Agricultural Development Program (TADP) respectively. These were collated and analyzed using standardized anomaly index and linear regression in SPSS environment. The study fails to reject the null hypotheses that no relationship exists between the average annual rainfall and quantity of sorghum produced annually. It recommends application of biotechnology using (<em>Sorghum bicolor</em> L. Moench) for animal feeds and food crop diversification to cushion the ever increasing demand for forage that often vortex crisis in the state. SFF can stand heavy grazing reduce roaming encourage ranching eliminate crisis.</p> Adelalu Temitope Gabriel Mohammed Bakoji Yusuf Benjamin Ezekiel Bwadi Yakubu G.

Nutrient management practices on long-term basis differentially influence aggregates and distribution of soil organic C (SOC) present within aggregates, which in time may affect C stabilization. The present study assessed the impact of long-term application of fertilizers for 44 years either alone or integration with farmyard manure (FYM) on bulk density, SOC and C pools, potassium permanganate oxidizable C (KMnO<sub>4</sub>), aggregate stability and distribution of C fractions within different size aggregate under maize-wheat cropping sequence. The application of 100%NPK+FYM significantly (P&lt; 0.05) improved soil aggregation and mean weight diameter (MWD). The percent of macro-aggregates (MacroA) and meso-aggregates (MesoA) was maximum in 100%NPK+FYM followed by NPK and the minimum in the control treatment. Irrespective of aggregate classes, TOC (g kg<sup>-1</sup> aggregate) was maximum in 100%NPK+FYM treatment with an average of 8.42 g kg<sup>-1</sup> aggregate as compared to control (5.05 g kg<sup>-1</sup> aggregate). If averaged across the treatments, TOC concentration in aggregates followed the order MacroA&gt; MesoA&gt;MicroA. Correspondingly, results for KMnO<sub>4</sub>-C were similar in different treatments and aggregate classes. Application of FYM with inorganic fertilizers (NPK) or NPK showed a significant increase in all oxidizable organic C fractions particularly recalcitrant C fraction, which reflects the stable nature of OC as compared to very labile and labile C fractions. In general, C present in mineral fraction and large-sized aggregates (MacroA) has higher recalcitrant fractions of SOC as compared to small-sized aggregates (MesoF and MicroF). The study concluded that long-term balanced and integrated nutrient management improved soil aggregation, C distribution within aggregates, and C storage capacity of soils under maize-wheat. Carbon associated with macro aggregate and a mineral fraction has more recalcitrant C fraction compared to meso and micro aggregate fractions.</p> Anmol Singh G. S. Dheri D. K.

Quantity of production from cereal croplands are partly a function of climatic elements and are connected to the pulses of climatic variation. Hence, this paper assessed temperature variability effect on rice production in Nasarawa State, Nigeria. Daily maximum and minimum temperature data were obtained from the Nigerian Meteorological Agency and converted into monthly averages while annual rice production data was obtained from the office of Nasarawa State’s Agricultural Development Programme. Acquired data were analysed using Linear Multiple Regression Model, coefficient of variation and spatial data analysis techniques. Although rice production in the State is being affected by the fluctuations in both minimum and maximum monthly temperature, the later poses grave concern for sustainability of rice production with a negative effect size of -3.145 and a coefficient value of -191,324.30 metric tons. This negative impact of maximum temperature fluctuations on rice production indicates that rice production in Nasarawa State is vulnerable to climate variability with increasing maximum temperature. LGAs in the south senatorial district has more favourable locations for rice production in comparison to those in the North and West districts given that less temperature fluctuation was observed in the former. Government and non-governmental institutions as well as individuals planning to establish rice farm project(s) in the study area should consider doing so in the South Senatorial District in order to avoid the adverse effect of temperature variability.</p> Oladeinde Stephen Olufemi Magaji I.

Natural geological sources and increased industrialization have contributed greatly to the increasing incidence of F-induced human and animal health issues. The toxic effects of high doses of F may adversely affect human health by causing skeletal fluorosis, dental fluorosis, bone fractures, the formation of kidney stones, decreased birth rates, weakening of thyroid functionality and impair intelligence, particularly in children. High concentrations of F in soil may seriously threaten the life of plants, devastate soil microbial activity, disrupt the soil ecology and causes soil and water pollution. Hydrogen fluorides (HF) in gaseous form accumulated in the leaves of sensitive plants against a concentration gradient and HF mainly damages the plant by entering into its body in the form of gas and affects a variety of plant physiological processes. In this review we discuss about the effect of fluoride toxicity on plant, human and soil health and its mitigation strategies.</p> Nitin Chatterjee Gayatri Sahu Animesh Ghosh Bag Biplab Plal G. C.
