Climate change has b.en a glob.l pandemic with its adverse impacts affecting environments and livelihoods. This has b.en largely attrib.ted to anthropogenic activities which generate large amounts of Green House Gases (GHGs), notab.y carb.n dioxide (CO2), methane (CH4), and nitrous oxide (N2O) among others. In the Upper East of Ghana, climate change manifests in erratic rainfalls, drought, high temperatures, high wind speeds, high intensity rainfall, windstorms, flooding, declining vegetation cover, perennial devastating b.shfires etc. Practices such as b.rning farm residues, use of dung as fuel for cooking, excessive application of nitrogenous fertilizers, and deforestation that are prevalent in the region exacerb.te the situation. Although, efforts made b. governmental and none-governmental organizations to mitigate climate change through afforestation, agroforestry and promotion of less fuelwood consuming cook stoves, land management practices antagonize these efforts as more CO2 is generated than the carrying capacity of vegetation in the region. Research findings have estab.ished the role of trees and soil in carb.n sequestration in mitigating climate. However, there is limited knowledge on how the vegetation and soil in agroforestry interplay in mitigation climate change. It is against this b.ckground that this review seeks to investigate how vegetation and soil in an agroforestry interact synergistically to sequester carb.n and contrib.te to mitigating climate change in Upper East region of Ghana. In this review, it was discovered soil stored more carb.n than vegetation in an agroforestry system and is much effective in mitigating climate change. It was found out that in order to make soil and vegetation in an agroforestry system interact synergistically to effectively mitigate climate change, Climate Smart Agriculture practice which integrates trees, and perennials crops effectively mitigates climate. The review concluded that tillage practices that ensure r

Our ob.ectives were to test the potential replacement of fish meal b. sesame oil cake(SOC) in high energy diets fed to rainb.w trout(RT,Oncorhynchus mykiss) and b.own trout(b.,Salmo trutta fario).Groups of trout(initial b.dy weight(b.) of 1.42 g for RT and 1.48 g for b.) were fed to visual satiety with isonitrogenous(61 g digestib.e N kg dry matter(DM)) high-energy (22.1 MJ kg DM ) freeze-dried diets,in which fish meal was progressively replaced b. SOC(0, 13,26,39 and 52%,on a N b.sis).Apparent digestib.lity coefficient(ADC) of the diets was determined using the indirect method.A growth trial was conducted over feeding 45 days at 15±0.6℃.Protein digestib.lity was high(91%) and was unaffected b. either diet or *** of energy was reduced b. 5.5%in b.th species when SOC replaced 52%of fish meal protein and was significantly higher in b. compared to *** rate increased when SOC progressively replaced fish meal until reaching a maximum at a sub.titution rate of 39%for RT and 26%for b..

为了提高棉花病害的识别率,提出了一种在自然环境条件下基于粗糙集和b.神经网络的棉花病害识别方法。该方法以轮纹病、角斑病、褐斑病和盲椿象为研究对象,将病害棉花图像从RGb.色空间转换到HSI和L*a*b.颜色空间,应用Otsu算法对H分量、a*分量和b.分量进行阈值分割,通过H+a*+b.分量与原始图像的交集提取棉花病斑区域,利用颜色矩和灰度共生矩阵分别提取病斑的颜色和纹理特征,并结合粗糙集理论和b.神经网络,实现特征向量的优选,和棉花病害的识别。通过比较试验发现,粗糙集理论能有效减少特征维数,使提取的全部特征向量16个减少到5个,使b.神经网络的训练时间缩短到原来的1/4,且棉花病害平均识别正确率达到92.72%。研究结果表明,该方法准确识别了4种棉花病害,为棉花病害的防治提供了有效的技术支持。
