Abstract The efforts of businesses, governmental and non‐governmental organizations notwithstanding, unsustainable consumption continues to threaten society's vision sustainable development. Green purchasing, therefore, offers a chance reducing negative environmental impacts promoting Yet, the question how encourage green purchasing behaviour remains poorly understood. Based on theory values, this paper examines antecedents intentions among young adults in Chinese cities. structural equation...
Crimean-Congo Haemorrhagic Fever Virus (CCHFV) is a zoonotic virus transmitted by Ixodid ticks and causes hemorrhagic fever (CCHF) disease in humans with up to 50 % mortality rate.Freshly slaughtered livestock at the Kumasi abattoir Ashanti Region of Ghana were examined for presence once month over 6-month period from May November 2011. The grouped into pools species, sex, animal source. CCHFV was detected using reverse transcription PCR. Blood samples collected enrolled workers initiation,...
In late 2018, unusual patterns of very high mortality (>50% production) were reported in intensive tilapia cage culture systems across Lake Volta Ghana. Samples fish and fry collected analysed from two affected farms between October 2018 February 2019. Affected showed darkening, erratic swimming abdominal distension with associated ascites. Histopathological observations tissues taken moribund at different revealed lesions indicative viral infection. These included haematopoietic cell...
Abstract The role of Africa in the dynamics global spread a zoonotic and economically-important virus, such as highly pathogenic avian influenza (HPAI) H5Nx Gs/GD lineage, remains unexplored. Here we characterise spatiotemporal patterns virus diffusion during three HPAI intercontinental epidemic waves demonstrate that mainly acted an ecological sink viruses. A joint analysis host continuous spatial indicates poultry trade well wild bird migrations have contributed to spreading into Africa,...
Highly pathogenic avian influenza virus A/H5N1 was first officially reported in Africa early 2006. Since the outbreak Nigeria, this spread rapidly to other African countries. From its emergence 2008, 11 countries experienced outbreaks poultry and human cases were also three of these At present, little is known epidemiology molecular evolution viruses Africa. We have generated 494 full gene sequences from 67 isolates applied analysis tools a total 1,152 obtained isolated Africa, Europe Middle...
The phylum Apicomplexa includes parasites of medical, zoonotic and veterinary significance. Understanding the global distribution genetic diversity these protozoa is fundamental importance for efficient, robust long-lasting methods control. Eimeria spp. cause intestinal coccidiosis in all major livestock animals are most important domestic chickens terms both economic impact animal welfare. Despite having significant negative impacts on efficiency food production, many questions relating to...
Soybean is an important cash crop especially for farmers in the north of Ghana. However, cultivation commodity dominated by smallholders equipped with traditional tools, coupled low or no adoption improved soybean production technologies. Using primary data collected from 300 across northern Ghana, study employed count modelling to estimate determinants intensity sustainable The accounted potential estimation errors due under-dispersion and over-dispersion, using a model based on generalized...
Between November 2017 and February 2018, Ghanaian poultry producers reported to animal health authorities a dramatic increase in mortality rate relevant drop egg production several layer hen farms. Laboratory investigations revealed that the farms had been infected by H9N2 influenza subtype. Virological molecular characterization of viruses identified Ghana is described here for first time. Whole genome analysis showed belong G1-lineage cluster with North West Africa. The low pathogenicity...
This study examined the effectiveness of various agricultural technology transfer methods using primary data collected from 543 rice farmers in Northern and Upper East regions Ghana. We employed descriptive statistics supported by Kendall's W-test chi-squared distribution test to identify assess their perceived effectiveness. In order importance, we found farmer-to-farmer approach, demonstration fields, household extension, radio as main extension use area. a significantly low patronage mass...
The enhancement of agrarian productivity through the use improved technologies such as fertilizer application is a critical avenue for increasing farm income, minimizing poverty, and tackling soil nutrient mining. This study has examined adoption decisions using data collected from 226 smallholder cocoa households in Western region Ghana. Heckman's two-stage model was employed to estimate probability extent Ghanaian farms. result indicated that likelihood influenced by factors farmers'...
The need for practising modern techniques in rice production has become increasingly important Ghana as the per capita cultivable land continues to shrink. This study employed a multivariate probit model estimate determinants of adoption improved agricultural technologies using household data collected from 543 farmers Upper East and Northern region Ghana. There was complementarity among all (i.e. nursery establishment, harrowing, line planting, spacing, urea briquette, irrigation, bunding)....
Abstract Background Achieving food security is a global priority and concern for most African countries, including Ghana. Food systems providing varied healthy diets without compromising the natural resource base, such as integrated crop–livestock diversification, are important development planning policy. Using cross-sectional data obtained from 1284 smallholder households in northern Ghana, we used double-censored Tobit model conditional mixed-process (CMP) framework to estimate impact of...
The survival of five mycoplasma strains was studied in different storage media (mycoplasma complete without cryopreservative agent, with addition horse serum, glycerol and lyophilized cultures stabilizer) under temperatures (+37 °C, +4 -20 -85 °C) for 24 months. Five strains, Mycoplasma mycoides mycoides, bovis, agalactiae, gallisepticum synoviae were isolated from various parts the country. initial titers determined by agar plate count before 42.4x107 UFC/ml (8.6 log UFC/ml) strain;...
Small-scale commercial poultry production is emerging as an important form of livestock in Africa, providing sources income and animal protein to many poor households, yet the occurrence impact coccidiosis on this relatively new system remains unknown. The primary objective study was examine Eimeria parasite small-scale farms Ghana, Tanzania Zambia. Additionally, farm economic viability measured by calculating gross margin enterprise budget.

This study employs stochastic frontier analysis (SFA) correcting for sample selection bias, to determine technical efficiency (TE) and technology gap using cross-sectional data collected from 543 rice farmers in Northern Ghana. The results showed that corrected TE estimates were marginally higher. Without the appropriate corrections, inefficiency is overestimated, while performance between irrigation their rainfed counterparts underestimated. We recommend authorities Ghana should work with...
Abstract To trace the evolution of highly pathogenic influenza A(H5N1) virus in West Africa, we sequenced genomes 43 viruses collected during 2015 from poultry and wild birds 5 countries. We found 2 co-circulating genetic groups within clade 2.3.2.1c. Mutations that may increase adaptation to mammals raise concern over possible risk for humans.
