    Management of insect pests of cocoa (Theobroma cacao L.) using insecticides began in 1950 and has since gone through various programmes with concomitant challenges and successes. Presently Imidacloprid (Confidor®), Bifenthrin (Akatemaster®) and Thiamethoxam (Actara®)are recommended by Ghana Cocoa Board (COCOBOD) for the management of insect pests. A survey was conducted in the Ashanti, Eastern, Volta and Western Regions of Ghana using questionnaires and farm visits of 147 cocoa farmers’ fields to gather information on the characteristics of the farmers and insecticide handling and use by respondents. The survey showed that males dominated cocoa farming (72.7%) and most of them aged between 50 and 60 years. About 44% have had basic education whilst 37.5% of them belonged to farmer based organizations. About 52.8% of the farmers own motorized mistblower but 47.2% of the farmers use knapsack in the absence of a mistblower. About 44.8% do their own spray application whereas 55.2% hire labour. About 60.9% of the population across the regions read the label on the insecticides before application. A few (31.6 %) of the respondents put on the full personal protective costume during insecticide application and 21.9% do not use any protection. There was a positive correlation between farmers’ membership of farmer-based organisation and the costume-wearing farmers in the Ashanti, Eastern and Volta Regions and it was significant in the Ashanti region. It isrecommended that training and monitoring programmes be organized for farmers on the need to handle pesticides properly for personal and environmental safety and consumer benefit.Keywords: Insecticides; pest management; cocoa farmers; safet

    Abstract: A detailed agro-ecosystem characterization was carried out in the Kpene catchment of the Jolo-Kwaha watershed in Northern Ghana at a scale of 1:5000. The objective was to examine the environmental and socio-economic characteristics of the Kpene area and identify the constraints on sustainable agricultural production, especially soil and water management. Environmental data, particularly land use and soil types were obtained through transect surveys while socio-economic data through participatory rural appraisal (PRA) techniques. The area falls within the Guinea Savanna agro-ecological zone of Ghana with a unimodal rainfall regime. With a Land Use Ratio (LUR) of almost 100%, land use is very intense and fallow is almost non-existent the farming system. The uplands have mainly deep, well -drained and nonconcretionary Lixisols, and the lowlands, deep and imperfectly to poorly drained Planosols and Gleysols. The Kpene community has an average of 40 persons per household, with majority (45%) being between 15-45 years of age. The major occupation is farming with land ownership being entirely through inheritance. Major crops grown are maize, yam, rice and groundnuts. In soil fertility management, 70% apply mineral fertilisers, especially to rice. Some constraints on agricultural production are erratic and unreliable rainfall, low soil fertility and poor water management. Levelling for proper water conservation in the valley bottoms and water harvesting can enhance agricultural production

    1. Abstract 1.1. Background: Evidence suggests that diabetes in all forms are on the rise especially gesta-tional diabetes mellitus which increases the risk of maternal and neonatal morbidities; however global prevalence rates and geographical distribution of GDM remain uncertain. The aim of this study is to examine the global burden of gestational diabetes mellitus. 1.2. Methods: A systematic review and meta-analysis of studies reporting Randomised Clinical Trials (RCTs) in pregnant women who have GDM was conducted. Cochrane (Central), PubMed, Scopus, JBI, Medline, EMBASE and reference lists of retrieved studies were searched from inception to March 2019. Publications on prevalence of GDM irrespective of the baseline criteria used to diagnose GDM were included in the study. Studies were limited to English language, randomised control trials and women aged between 19-44 years inclusive. 1.3. Results: Eleven RCTs met the inclusion criteria for this review. The included studies collectively reported GDM rates of 13,450 pregnant women from 7 countries. The diagnostic criteria used in the studies were World Health Organisation (WHO) 1985 and 1999, International Association of Diabetes, Pregnancy Study Group (IADPSG), National Diabetes Data Group (NDDG), Carpenter-Coustan (C&C) and O'Sullivan's criteria. Seven RCTs screened for GDM in comparison with different diagnostic criteria in the same population while three studies used the same criteria for different groups. One study compared 100g, 3h OGTT to 75g, 2h OGTT for diagnosing GDM using Carpenter and Coustan criteria. All seven RCTs that compared different diagnostic criteria in the same population detected different prevalence rates of GDM. Three RCTs measured prevalence of GDM in the same population using WHO 1999 and IADPSG 2013 criteria. Using random effect model, data from three studies that compared IADPSG criteria to WHO 1999 showed an Odds Ratio (OR) of 0.52(0.15, 1.84), 95% Confidence Interval (CI) and high heterogeneity of 99%. In all three studies, prevalence of GDM measured by IADPSG criteria was higher than WHO 1999 criteria, although not significant (p= 0.31). Combining all the studies gave a global estimated prevalence of GDM to be 10.13% (95% CI, 7.33-12.94) with moderate heterogeneity of 27%. The highest prevalence of GDM wit

    Perceived stressors of climate vulnerability across scales in the Savannah zone of Ghana: a participatory approach

    Get PDF
    Smallholder farmers in sub-Saharan Africa are confronted with climatic and non-climatic stressors. Research attention has focused on climatic stressors, such as rainfall variability, with few empirical studies exploring non-climatic stressors and how these interact with climatic stressors at multiple scales to affect food security and livelihoods. This focus on climatic factors restricts understanding of the combinations of stressors that exacerbate the vulnerability of farming households and hampers the development of holistic climate change adaptation policies. This study addresses this particular research gap by adopting a multi-scale approach to understand how climatic and non-climatic stressors vary, and interact, across three spatial scales (household, community and district levels) to influence livelihood vulnerability of smallholder farming households in the Savannah zone of northern Ghana. This study across three case study villages utilises a series of participatory tools including semi-structured interviews, key informant interviews and focus group discussions. The incidence, importance, severity and overall risk indices for stressors are calculated at the household, community, and district levels. Results show that climatic and non-climatic stressors were perceived differently; yet, there were a number of common stressors including lack of money, high cost of farm inputs, erratic rainfall, cattle destruction of crops, limited access to markets and lack of agricultural equipment that crossed all scales. Results indicate that the gender of respondents influenced the perception and severity assessment of stressors on rural livelihoods at the community level. Findings suggest a mismatch between local and district level priorities that have implications for policy and development of agricultural and related livelihoods in rural communities. Ghana’s climate change adaptation policies need to take a more holistic approach that integrates both climatic and non-climatic factors to ensure policy coherence between national climate adaptation plans and District development plans

    The Effects of Business Failure Experience on Successive Entrepreneurial Engagements: An Evolutionary Phase Model

    Get PDF
    This study draws insights from the literatures on entrepreneurial learning from failure and organizational imprinting to develop an evolutionary phase model to explain how prior business failure experience influences successive newly started businesses. Using multiple case studies of entrepreneurs located in an institutionally developing society in Sub-Sahara Africa, we uncover four distinctive phases of post-entrepreneurial business failure: grief and despair, transition, formation and legacy phases. We find that while the grieving and transition phases entailed processes of reflecting and learning lessons from the business failure experiences, the formation and legacy phases involve processes of imprinting entrepreneurs’ experiential knowledge on their successive new start-up firms. We conclude by outlining a number of fruitful avenues for future research

    The use of adherence aids by adults with diabetes: A cross-sectional survey

    Get PDF
    BACKGROUND: Adherence with medication taking is a major barrier to physiologic control in diabetes and many strategies for improving adherence are in use. We sought to describe the use of mnemonic devices and other adherence aids by adults with diabetes and to investigate their association with control of hyperglycemia, hyperlipidemia and hypertension. METHODS: Cross sectional survey of diabetic adults randomly selected from Primary Care practices in the Vermont Diabetes Information System. We used linear regression to examine the associations between the use of various aids and physiologic control among subjects who used oral agents for hyperglycemia, hypercholesterolemia, and hypertension. RESULTS: 289 subjects (mean age 65.4 years; 51% female) used medications for all three conditions. Adherence aids were reported by 80%. The most popular were day-of-the-week pill boxes (50%), putting the pills in a special place (41%), and associating pill taking with a daily event such as a meal, TV show, or bedtime (11%). After adjusting for age, sex, marital status, income, and education, those who used a special place had better glycemic control (A1C -0.36%; P = .04) and systolic blood pressure (-5.9 mm Hg; P = .05) than those who used no aids. Those who used a daily event had better A1C (-0.56%; P = .01) than patients who used no aids. CONCLUSION: Although adherence aids are in common use among adults with diabetes, there is little evidence that they are efficacious. In this study, we found a few statistically significant associations with adherence aids and better diabetes control. However, these findings could be attributed to multiple comparisons or unmeasured confounders. Until more rigorous evaluations are available, it seems reasonable to recommend keeping medicines in a special place for diabetic adults prescribed multiple medications
