Slope Position and Land Use Effect on Select Soil Properties, Quality and Carbon Stock in Surface Soils at Afaka Forest Area, Northern Guinea Savanna of Nigeria | Chapter 03 | Current Research in Science and Technology Vol. 2

Population increase and the need to achieve food security; especially in Nigeria, necessitated encroachment into forests and marginal lands for agricultural land uses in the Savanna ecologies. However, tropical soils are inherently fragile and prone to rapid degradation under intensive agriculture; especially when soil cover is removed and the soil tilled conventionally. Also, Savanna Alfisols are low in inherent fertility, organic matter, cation exchange capacity, dominated by low activity clays and sesquioxides. The increasing incidence of soil degradation and nutrient impoverishment of the savanna ecologies resulted in decreasing soil quality, agricultural production and increasing farmer food insecurity that generated interest in the need to evaluate effect of slope and Land use on soil properties, quality and carbon stock on Afaka soils in Nigerian Guinea Savanna. Data generated were analyzed using ANOVA and significant means were determined using Duncan multiple range test (DMRT). Results obtained reveal that cultivation activities and erosion accounted for increased silt (19.10 %) in cultivated areas than forest areas (14.89%), while sand fractions (54.44%) dominate separates in the Forest and the cultivated land uses. Upper slope positions had the highest sand content (71.67%), followed by lower slope with 68.00%, then middle (67.67%) slopes. Silt contents at the middle slope positions were significantly higher than at upper (15.33%) and Lower slope Position (17.00%) and clay values increased in the lower slope terrains. Also, organic carbon varied significantly between the land use types and slope position on the toposequence. At the forest areas, organic carbon was 10.2 gkg-1 and higher significantly than Cultivated fields (8.2 gkg-1). At the upper slope fields under cultivation, organic carbon value was 8.7 gkg-1 and was significantly lower than Middle slope (9.60 gkg-1) and Lower slope terrains (6.30 gkg-1). Under Forest land use also, Middle slope terrains had significantly higher organic carbon content than Upper slope terrains. The high Carbon stock of the forest middle slope terrain (1.77 tCha-1), followed by forest land use type would discourage global warming and climate change within the Afaka environment However, carbon stock in forest Land use type in Afaka areas (1.41 tCha-1) was significantly higher than cultivated land use types (1.21 tCha-1). At cultivated slope terrains, middle slopes retained significantly higher SOC (1.37 tCha-1) than upper and lower slope terrains. Considering soils for prime quality, soils under forest lower slope terrain ranked best quality (SQ1; prime quality) for sustainable cultivation purposes, followed by cultivated middle slope and forest land use type that ranked SQ2. Cultivated upper slope soils ranked least (SQ6) in quality for use in crop production, while cultivated lower slope and cultivated land use type soils ranked SQ5. However, increasing loss of forests to intensive cultivation activities without adequate soil management practices would portend increase in global warming and climate change in the study area.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t
