One of the key measures to fight urban heat island (UHI) phenomenon is by increasing the use of green approaches including green technologies and vegetation. However, there is a shortage of available space for establishing greening elements due to high density of urban development and high cost of urban land. By using green roofs, the hottest spots of a city can be mitigated. Further advantages of green roofs include mitigating air pollution, improving management of run-off water, improving public health and enhancing the aesthetic value of the urban environment. This paper reviewed, analyzed, and discussed previous literature on green roofs and their role in alleviating UHI. Previous researches acknowledged the ability of green roofs in UHI mitigation. This paper recommends using green roofs as a main strategy for decreasing the harmful impacts of UHI especially the high air temperatures as well as their ability to add to the greening of cities.

The present study was conducted to study the physico-chemical characteristics (proximate and ultimate analyses, particle size distribution, energy content and ash analyses) and investigate the combustion behaviour of empty fruit bunch (EFB)-derived biochar (EFBC) as potential solid fuel for power generation.

Factors influencing the decline of export value among Bumiputera furniture manufacturer have been discussed previously. Although the furniture industry contributes the largest number in export value, the participation among Bumiputera manufacturer is very small. This scenario is disrupted because the existing Bumiputera furniture manufacturer is unable to continue their business sustainability due to increase competition or weakness from various aspect of entrepreneurship and other factors. In addition, this industry becomes more worsening with the lack of clusters that can continue the survival of Bumiputera furniture manufacturer. This article seeks to investigate the influential factors and identify the most influential aspects that drive to decline of Bumiputera furniture export. A questionnaire was distributed to more than 30 company and analyzed by using Statistical Package for Social Sciences (SPSS) to test the reliability. The further analyzed was using frequency analysis and descriptive mean test. The findings have important implications for future research direction towards a better performance and capabilities to the organization.

Grassroots innovation is an activity that uses multiple resources or indigenous technology to create an innovation more creatively. The innovations are often utilised to improvise the community and environment. The invented product or process is created at the bottom of the pyramid due to necessities, difficulties, and challenges. Malaysia thrives to become a high income developed nation through several initiatives, such as lifelong learning and innovation. Malaysians are encouraged to undertake education programmes to enhance knowledge and skills. These grassroots activities need to be discovered as they affect income and social values. The local grassroots innovators have difficulty commercialising the innovations due to a lack of skills, knowledge, and technology. This study aimed to identify the grassroots innovations, the process in developing innovation, and complement the innovation towards commercialisation. Local innovators adapt to the new product development process as a mutual understanding and for grassroots sustainable development.
