INTRODUCTION Definition and Explanation of some Terms What is a chemical industry? It is difficult to define chemical industry exactly because of the absolute necessity for chemicals in almost every manufacturing industry. However, chemical industry can be defined as one that consists of all companies engaged in converting raw materials obtained from the environment (air, water, petroleum, minerals, agricultural products etc) into basic chemicals or chemical intermediates as well as the co...
Abstract: Governance systems and structures are a critical determinant to whether countries will achieve their aspirations especially on matters of development. In its quest to spur development and combat challenges like marginalization and poverty, Kenya decided to shift its governance system from a more centralized to a devolved system under the new constitution that was promulgated in the year 2010. This research therefore sought to investigate whether devolution has had an impact in redu...
ABSTRACT The study informs about the influence of climate change on cashew nuts pests and diseases as well as strategies employed by farmers to minimize the impact in Mtwara District. Two wards of Nitekela and Nanguruwe in the District were used to generate the data. Specifically, the study examined trend of climate parameters (rainfall, temperature and relative humidity) in the study area, the impact of climate change on cashew pests and diseases and lastly the strategies employed by farmer...
ABSTRACT This project examines the use of GIS in creating an agro-climatic zone map. The map recognizes that the major aspects of climate that affect plant growth are moisture availability and temperature. The agro-climatic zones are therefore specific combinations of moisture availability zones and temperature zones. The project was undertaken following the variability of rainfall and recurrent droughts in the country that affects the lives of millions of people whose livelihood is mainly de...
ABSTRACT This study is concerned with overview numerical solution for nonlinear partial dierential equations. Since it is not easily to iterate the numerical scheme manually, C++ is used to encode the numerical scheme in order to nd the numerical solution and Matlab is employed in drawing the gures. Chapter one consists of Introduction of Nonlinear Partial Dierential equations, Literature Review, Classication of Partial Dierential Equations, Examples of PDEs, Boundary Conditions, Taylor Expan...
This study was designed to determine the effect of visual-aided instruction on students’ achievement in Agriculture in Junior Secondary schools. Two specific purposes, research questions and two null hypotheses guided the study. Quasi-experimental research design was adopted and the population for the study was 2,620 Junior Secondary School two (JSS2) students in Lafia metropolis, Nasarawa State, out of which 284 were sampled using purposive sampling technique. The instrument for data colle...
Abstract Household livelihood across Africa 50 years after independence have recorded lean improvements especially in terms of access to essential production inputs. Household rate of land access, means of access, Household rate of land access, means of access, welfare and investment capacities, land cost and the linkage between access to land and the above measured parameters were investigated using a set of questionnaires administered to urban and rural settlements. Descriptive results show...
Abstract Climate change is currently a serious threat for agriculture development and food security in sub-Saharan Africa. With the Intergovernmental Panel on Climate Change (IPCC) climate outlook for the 21st century, the future of maize production in Tanzania remains under threat due to more intense and frequent droughts, and more erratic rainfall patterns. Effective adaptation to these ongoing changes in climatic condition is key to securing food production and livelihoods for millions of ...
ABSTRACT Indigenous knowledge is the local knowledge unique to a given culture or society. It is the basis of decision making in agriculture, healthcare, food preservation and natural resource management. This study was set to establish the existence of Indigenous knowledge in the community of Chwele and Mukuyuni wards of Bungoma Central Sub-County, Bungoma County and its role in seasonal climate forecast. The general objective of this study was to examine the role of indigenous knowledge in ...
ABSTRACT Pollution of the aquatic environment is a major global concern as it is emerging that pollutants such as organic compounds are rising each day. The anthropogenic activities such as agricultural and wastewater effluent contribute to the pollution of aquatic resources. The aim of this study was to determine the spatial occurrence and concentration of organic compounds in water and sediment along Sebakwe River in Kwekwe. Water and sediment samples were collected once in January 2019 at...
ABSTRACT Knowledge of soil spatial variability and the relationships among soil properties are important for the evaluation of agricultural land management practices and soil research. The study was conducted to assess the spatial variability of selected soil properties on a 2.17 ha field at the School of Agriculture Teaching and Research farm from March to October, 2010. A stratified random sampling design was employed in the study. Samples were collected from two depths 0-10 cm and 10-20 c...
ABSTRACT Aspects of the ecology and spatial context of Etse Lagoon at Abandze, in the Central Region of Ghana were studied from April 2014 and March 2015. Water temperature ranged from 24.0 ⁰C to 36.6 ⁰C (mean = 29.43 ± 0.12 ⁰C). Salinity varied from 0.72 ‰ to 22.30 ‰ (mean = 13.42 ± 0.30 ‰), pH from 4.6 to 8.9 with a mean value of 7.6 ± 0.03, DO from 1.65 mg/l to 11.15 mg/l with a mean value of 5.08 ± 0.08 mg/l and conductivity from 7.35 mS/cm to 43.3 mS/cm with a mean value...
ABSTRACT Climate change exacerbates the already daunting challenge facing the agricultural sector, and this is particularly the case in developing countries. There are roughly 800 million food insecure people in the world today, each having this status because food is unavailable, unaffordable or they are too unhealthy to make use of it or some combination of the three. Innovations in agriculture will even be more vital in the context of climate change as they allow farmers to adapt efficient...
ABSTRACT For the course of this study, a total of 100 specimens of Hydrocynus forskahlii were collected at different stages of life from Ureje Dam, Ado Ekiti, Ekiti State, between the period of .September and October, all fish samples of Hydrocynus forskahlii was carefully examined to avoid damage to any of the morphometric characteristics of the fish. The measurements for (he morphometric characteristics of each of the investigated tiger fish specimen was carried out in the Fisheries and A...
ABSTRACT This study was undertaken to analyse economic determinants for households involvement in fishing for livelihoods in coastal villages of Bagamoyo District. Specifically, trend in the number of fishers for ten years in coastal villages were determined, factors influencing household decision to be involved in fishing were examined and household income structure was analysed. Three villages were randomly selected and thirty households were randomly selected from each village. Primary da...
