In the era of climate change, irrigation is playing a pivotal role in stabilising food production, enabling dry season farming, and improving farmers’ livelihoods, particularly in Asia and African countries. Recently, Ghana has taken steps to respond to the concept of stakeholder collaboration to improve the irrigated agricultural sub-sector as well as enhance farmers’ resilience to changing climate. However, there is limited attention to recent diverging experiences on collaborative practices from irrigation stakeholders. Using the Weija Irrigation Scheme as a case study, this study explores stakeholders’ perceptions of collaborative practices in irrigation management by identifying gaps and providing suggestions to enhance stakeholder collaboration. We conducted focus group discussions with farmers and in-depth interviews with key informants, such as heads of farmer groups, government departments, agencies, and agricultural extension agents. Secondary data from conventional literature, organisational websites, and quarterly reports were also used. Following the integrated collaboration governance theory, effective collaboration was measured based on the tripartite prism of “principled engagement, shared motivation, and capacity for joint action”. Analysis of the data reveals that despite the central government’s resolve for collaborative irrigation planning and management, effective collaboration remains limited. Based on principle engagement, this study points out  that weak communication and sharing of information remain in the planning and management of the Weija Irrigation Scheme. In terms of shared motivation, there were minimal commitment to joint project planning, exclusion of some key stakeholders from meetings, and negative attitudes towards collaboration. Finally, the capacity for joint action (e.g. lack of fund, time, staff, and equipment) is limited. The policy implications and suggestions for further research are presented in the study.

PurposeHeating, ventilation and air-conditioning (HVAC) systems account for approximately half of all energy usage in the operational phase of a building's lifecycle. The disproportionate amount of energy usage in HVAC systems against other utilities within buildings has proved a huge cause for alarm, as this practice contributes significantly to global warming and climate change. This paper reviews the status and current trends of energy consumption associated with HVAC systems with the aim of interrogating energy efficiency practices for improving HVAC systems' consumption in buildings in the context of developing countries.Design/methodology/approachThe study relied predominantly on secondary data by analysing the relevant body of literature and proposing conceptual insights regarding best practices for improving the energy efficiency of HVAC systems in buildings. The systematic review of the literature (SLR) was aided by the PRISMA guiding principle. Content analysis technique was adopted to examine germane scholarly articles and finally grouped them into themes.FindingsBased on the SLR, measures for enhancing the energy efficiency of HVAC systems in buildings were classified based on economic considerations ranging from low-cost measures such as the cost of tuning the system, installing zonal control systems, adopting building integrated greenery systems and passive solar designs to major approaches such as HVAC smart technologies for energy management which have multi-year pay-back periods. Further, it was established that practices to improve energy efficiency in buildings range from integrated greening system into buildings to HVAC system which are human-centred and controlled to meet human modalities.Practical implicationsThere is a need to incorporate these energy efficiency practices into building regulations or codes so that built environment professionals would have a framework within which to design their buildings to be energy efficient. This energy efficient solution may serve as a prerequisite for newly constructed buildings.Originality/valueTo this end, the authors develop an integrated optimization conceptual framework mimicking energy efficiency options that may complement HVAC systems operations in buildings.

The promotion of environmental education through School Garden Programme (SGP) has gained global recognition. This stems from societies' growing awareness of the fundamental role school gardens play in environmental education and community adaptation to the changing climate. Although the concept is not new in Ghana, its implementation is confined to very limited number of schools. This article focuses on school gardening and addresses the barriers in its implementation to raise environmental awareness in Ghana. Drawing from garden-based educational studies, the study relied on databases such as Google Scholar, Science Direct, and Scopus for recent studies, complemented by grey literature sources. The study revealed that Ghana is making efforts in environmental educational activities but has not successfully integrated the concept of school gardening into classroom curriculum; There is also limited collaboration between the schools and the wider community as well as limited funding for setting up a school garden. These factors undermine the promotion SGP in Ghanaian school. As such, the study suggests that SGP can be enhanced by 1) involving community and relevant stakeholders to promote the benefits of school gardening for positive learning outcomes and behavioural improvements, 2) incorporating it into educational policies/school curriculum to allow students to connect and interact with the natural environment, 3) providing financial support to foster its sustainability, and 4) providing professional development of teachers on SGP to improve their school garden knowledge and skills. By adhering to these measures, existing and future SGP will achieve the desired social (education and health) and environmental outcomes in Ghana and Africa in general.
