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 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 The overall purpose of the study was to determine the perception of extension staff of manpower and institutional factors that constrain agricultural extension services in Benue State Agricultural and Rural Development Authority (BNARDA). The study was guided by three research purposes, namely: to describe the respondents’ socio-economic characteristics; to determine the perception of the extension staff on the number of extension staff as a manpower constrain; and to examine the e...
ABSTRACT The study was conducted to identify the challenges in administering the Cross River State Ministry of Agriculture, Nigeria. All the staff of the ministry constituted the population for the study. A proportionate sampling technique was used in selecting respondents, with twenty percent (20%) of respondents from each of the departments. Thus the total sample size for the study was one hundred and thirteen (113) respondents. Percentages, mean and frequency were used in the presentation...
The study examined smallholder yam farmer’s perception and response to climate variability and change. A multistage sampling technique was used to select the study districts, study communities and the sample size of four hundred respondents. Questionnaires, key informant interviews and focus group discussions were conducted to elicit relevant information from the respondents. Data were analysed using descriptive statistics, qualitative narratives, community resource maps, seasonal calendars...
ABSTRACT This study investigated the catch trends, spatial distributions, exploitation status, and reproductive potential of the sparids – Pagrus caeruleostictus, Dentex canariensis and Dentex gibbosus, in the coastal waters of Ghana. Samples of the species were obtained from commercial catches at Tema, Elmina and Sekondi from February 2016 to July 2017. Also used were secondary data from the Fisheries Scientific Survey Department and Fridtjof Nansen cruise reports. P. caeruleostictus was ...
ABSTRACT The dissemination of the relevant information for agricultural production is the institutional duty of all stakeholders committed to the development of agriculture of which the agricultural extension agent and his organisation play a prominent role. As a formal public (government funded) institution, the agricultural extension service has been observed to be undergoing a period of change in respect to the provision of material and financial resources to carry extension activities. As...
ABSTRACT Food security is the Millennium Development Goals (MDGs) one which for Kenya is relevant for eradicating poverty and hunger. Increased agricultural productivity would be solution to the world’s 870 Million (M) food insecure people. Approximately 10M people in Kenya, 51.45% of Western Kenya population and 50-70% of households in Kakamega County suffer chronic food insecurity. Small farm sizes, low yields, production shift from food crops to cash crops and low levels of skills and t...
EXECUTIVE SUMMARY The Forestry sector plays key roles in supporting the livelihood of all Rwandans by providing most of the energy consumed by the bulk population, controlling soil erosion and protecting water catchments and supplying other goods and ecological services. Hence, the present and future extent of forest coverage in Rwanda is central to sustainable development and climate change considerations. Currently, about 87% of the population and 70% of the country’s land area are de...
ABSTRACT The role of agricultural extension is vital to the diffusion of new technologies, but extension is currently not very effective in many African nations, with conventional extension approaches having minimal impact. In Kenya, there have been gaps on the availability of studies and documentation of the specific extension approaches and their influence on the acquisition of knowledge and skills for improved farm productivity despite the various extension efforts and resources put in pla...

Abstract: Most developing countries like Ethiopia are striving hard to solve acute protein deficiency in the diets of their increasing populations through cultivation of mushrooms in the urban areas without heavily depending on agricultural lands and capital. This study was conducted in Debre Berhan University, College of Natural and computational Sciences, with the aim of assessing the proximate chemical composition, biological efficiency and suitability of the selected substrates (Millet s...
