The Impact of Climate Change on Rainfall Patterns in Ghana: A Zoning Adaptation Strategy through Developing Agroforestry


Abstract


As a developing country in Africa, the effect of climate change is one of the sufferings of Ghana. The effect is much felt in rainfall variability because of the country over reliance on rainfall for agriculture. While various researches have studied the impact of climate change in Ghana, few among them have extended to its impact on rainfall pattern across all the ecological zones in the country. The trends in the rainfall from seven selected meteorological stations across all the ecological zones were analyzed using data from the NASA satellite. The Mann-Kendall and Sen’s Slope Test were used for the analysis. The study found decreasing trend in most of the monthly and yearly rainfall pattern across the ecological zones, and suggested cashew agroforestry as a zoning adaptation strategy.

Experimental Simulation of Red Sprites in a Laboratory

Experimental Simulation of Red Sprites in a Laboratory DOI:  https://doi.org/10.30564/jasr.v5i3.4858 Abstract Over the past three decades, research of high-altitude atmospheric discharges has received a lot of attention. This paper presents the results of experimental modeling of red sprites during a discharge in low-pressure air. To initiate ionization waves in a quartz tube, an electrodeless pulseperiodic discharge fed by microsecond voltage pulses with an amplitude of a few kilovolts and a repetition rate of tens of kHz were formed. In this case ionization waves (streamers) have a length of tens of centimeters. The main plasma parameters were measured at various distances along the tube. The measurements confirm the fact that ionization waves propagate in opposite directions from the zone of the main electrodeless discharge, just as it happens during the formation of red sprites.

Analysis of Chinese Citizens’ Perception and Its Differences of City Spirit: A Case Study of Hefei City DOI:  https://doi.org/10.30564/jgr.v5i3.4788 Abstract City spirit is the soul of the city. The spread of city spirit not only could establish a civilized specimen for citizens, but also create a good cultural atmosphere for the city. Hefei residents’ perception of city spirit is extensive, and most of Hefei citizens consider the expression words of city spirit are very appropriate, which is enlightened, open-minded, actual and innovate. Great majority of Hefei citizens willing to support the propaganda and promotion of the city spirit, and they think the promotion of the city spirit plays a key role in the way of city’s development. In addition,significant differences in the perception of urban spirituality emerge among residents with different economic and social characteristics. There are four aspects about how to enhance the public perception of city spirit, which including in...

Bond Behavior between Recycled Concrete Containing CDW and Different Types of Steel Bars

Bond Behavior between Recycled Concrete Containing CDW and Different Types of Steel Bars Abstract The operation of reinforced concrete structures is directly associated with the adhesion between the steel bar and the concrete, which allows the internal forces to be transferred to the reinforcement during the process of loading the structural elements. The modification of the concrete composition, with the introduction of recycled aggregate from construction and demolition waste (CDW), affects the steel-concrete interface and can modify the bonding stress, which is also influenced by the type and diameter of the bar used. In this work, the influence of the recycled fine aggregate (RFA) and types of steel bar on the steel-concrete bond was experimentally evaluated using the pullout test. Conventional concrete and recycled concrete, with RFA replacement level of 25%, were produced. Two types of steel rebars (i.e.,plain and deformed) with diameters of 10.0 and 16.0 mm were considered in th...
