Role of Agroforestry on Farmland Productivity in Semi-arid Farming Regions of Zimbabwe

Role of Agroforestry on Farmland Productivity in Semi-arid Farming Regions of Zimbabwe


Abstract

Farmland productivity is low in the semi-arid regions (NR IV and V) of Zimbabwe due to desertification and land degradation. Nevertheless, demand for food is increasing geometrically hence the need to increase output per unit area. Agroforestry (AF) which is an ecologically based and dynamic system that integrates multi-purpose trees on farms can increase productivity and offer resilience to climate change vagaries. However, the role of AF in Zimbabwean smallholder farming systems is still not well investigated. Therefore, this review explores the role of agroforestry on agricultural productivity in the semi-arid regions of Zimbabwe. The aim was to enhance sustainable food security among the rural poor through sustainable agriculture. Incorporating multi-purpose trees on agricultural lands can significantly restore soil productivity and offer soil resilience to erosion by water and wind. If well implemented, the AF can be a viable option in mitigating the impacts of drought on agriculture in these drier and marginalized areas.

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...
