An exploratory study into promoting construction health and safety in Ghana through public works procurement

The construction industry is commonly associated with high or increasing levels of work-related hazards with ensuing injuries and fatalities. Studies have shown that procurement can further promote good construction H&S practice as it occurs throughout the life cycle of a project. However, the use of procurement as an instrument to promote H&S practices in construction has received little attention till date especially in developing countries. For this reason, the research aimed to explore practical measures to improve construction H&S through public works procurement in Ghana. Qualitative data was collected through semi-structured interviews. Seven respondents (procurement managers, consultants and Quantity surveyors), selected through a non-probabilistic purpose sampling from public institutions participated in the survey. In Ghana, the Public Procurement Act, Act 663 which was introduced in 2003 to ensure sanity and value for money in public procurement provides guidelines for the procurement of public works. In view of this, a case study of the H&S management of project procured using the Act 663 was also carried out. This was done to ascertain how public works is carried out in the Ghanaian public sector setting by determining the various stakeholders involved, the processes the project underwent and the various considerations looked at especially under H&S. The results however indicated that the Act 663 has no clause that addresses construction H&S. The paper also finds that, H&S does not form part of the criteria for evaluating tenders. To address the constraints so as to improve upon construction H&S, certain recommendations are offered. These include the inclusion of non- ambiguous H&S requirements as criteria for evaluating tenders and the pricing of H&S items in bills of quantities. Additionally, practical measures to improving construction H&S in Ghana at the key stages of works procurement are also provided. It also includes the specific roles and involvements of other stakeholders in the procurement process

Adoption of rice cultivation technologies and its effect on technical efficiency in Sagnarigu District of Ghana

This study examined the adoption of rice cultivation technologies on farmers’ technical efficiency in Sagnarigu District. The stochastic frontier model was used to estimate the determinants of output and technical inefficiency while propensity score matching was also used to analyse the average treatment effect (ATE) and the average treatment effect on the treated (ATT). A total of 120 respondents comprising 60 adopters and 60 non-adopters were randomly selected from six communities in the District and interviewed using semi-structured questionnaires. Farm size, fertilizer, weedicides and household labour had positive and significant effect on rice output. Farmers who adopted the rice cultivation techniques were less technically inefficient than those who did not adopt. The ATT was 0.121 which implies that farmers who adopted the rice technologies increased their technical efficiency by about 12% and this was significant at 10% for the PSM with similar results obtained for the nearest neighbour matching. The ATE value of 0.102 which was also statistically significant at 10% means that farmers on the whole increased their technical efficiency by 10.2%. Moreover, the mean technical efficiency estimates for adopters and non-adopters were about 58% and 48% respectively under regression adjustment and inverse-probability weights. The existence of a technical efficiency gap of 10% between adopters and non-adopters of rice technologies emphasized the significant effect of technology adoption on farmer’s technical efficiency. The study recommends that more rice farmers should be encouraged to adopt the rice production technologies in order to improve their technical efficiency levels

Stakeholders' role in improving Ghana's construction safety

Health and safety (H&S) management has traditionally been the responsibility of the contractor. Most often, contractors are blamed for the accidents and other ill health that occur on their construction sites. H&S performance is, however, enhanced when there is effective collaboration between those involved in the construction process. This paper therefore explores the role of stakeholders in promoting construction H&S in Ghana through public works procurement. The four main stakeholders identified and evaluated in this study are the government, the client (employer), the contractor and the employee(s). Seven interviewees (comprising procurement managers, consultants and quantity surveyors) from public institutions in Ghana participated in the research. Data were collected using semi-structured interviews and were thematically analysed. Results indicate a conflict in the perceived functions and relation of these stakeholders in the construction process. To address the constraint to improving construction H&S, certain recommendations are offered. These include the identification of specific individuals responsible for supervision and employee training, the development of H&S policies by the government and contracts that clearly outline the contractual obligations of all parties involved. Additionally, the specific roles and involvements of other stakeholders in the procurement process in improving construction H&S are also outlined

Ecological modernization and water resource management: a critique of institutional transitions in Ghana

Published online: 05 Feb 2015Ghana is endowed with surface and ground water resources. These resources prior to the colonial era were managed by traditional societies through various conventional methods embedded in their cosmovision. However during the colonial and postcolonial regimes, in response to climate change, economic globalization, and population pressure, there has been a conscious shift from customary water management systems towards paradigms cast in the contemporary mould (legislation, policies, and institutions). These modern approaches have been shown over the years to be insufficient in ensuring water sustainability. This insufficiency manifests itself in the increasing water scarcity through anthropogenic-induced water resources degradation and severe climatic variability. Using content analysis, this paper reviews this transition, first to fully understand the intricacies of the evolution and second to draw lessons for better water resources management in Ghana. This paper contends that although Ghana’s water related institutions, laws, and policies are undergoing significant reforms, implementation and practice remains embedded in weak ecological modernization (EM). Institutionalizing a narrow conception of EM will only perpetuate ‘organized irresponsibility’ and permit the continued production of ecological problems, leaving open the question of whether modernization is compatible with ecological sustainability. Though customary water management approaches are not entirely devoid of limitations, simply branding them as obsolete may obviate an important vehicle for water sustainability. In the spirit paradigmatic complementarity, ecosystem-friendly indigenous approaches must be integrated with contemporary management systems for the long term goal of sustainability.Gerald Atampugre, De-Valera N.
