This issue of Planning Malaysia Journal includes a mixture of articles addressing various issues in contemporary urban planning. Article 1 raises the question of whether green initiatives in educational institutions, especially universities, were successful in producing green graduates. A survey among green and non-green universities students showed that there is no significant difference in the level of perception, attitude and responsible environmental behaviour between green and non-green universities graduates. Thus, it suggests that students’ involvement in universities’ green initiatives should be increased.Article 2 discusses the impacts of street urban design on the perceived safety by women respondents. As women’s role in the cities becoming more pronounced, the authors suggest that streets and urban design should consider the safety of women so that street can become a safe and highly utilised public space. Article 3 looks at the factors affecting house prices in Malaysia in order to determine the alternative benchmark for Islamic home financing scheme. It shows that house price index are influenced by economic growth, demand for housing loan and construction materials. Article 4, in the meantime, compares the Islamic home financing schemes on offer in Malaysia nowadays, and suggest that there is a need for banks to move on from the Al-Bay Bithaman Ajil to Musharakah Mutanaqisah Partnership housing financing scheme.Article 5 looks how innovative management of natural resources leads to increased participation of the local community and improved revenue for rural businesses. These, in turn, motivates local stakeholders to continue preserving the resources. Article 6 examines the practices regarding food waste management in hotels in Langkawi. It found that there was a lack of emphasis from the hotels on their policy related to wastage of food and unsustainable food consumption pattern by their guests. This reflects on the lack of practices towards sustainable food waste management by the hotel sector.Article 7 identifies changes and threats to Malay landscape preservation in traditional Malays houses in Melaka and Kelantan. It concludes that threats to such preservation include inappropriate use of garden space, problems regarding house ownership, inadequate fund for maintenance, and current development trend that leads to traditional Malay garden setting being replaced by modern setting.Article 8 discusses the use of agroforestry approach to improve sustainability of oil palm smallholdings. Rapid development and expansion of natural forest into oil palm land has decreased the agricultural sustainability of Malaysian oil palm production. However, the article shows that sustainability of oil palm smallholdings can be improved through agroforestry, which at the same time was found to also improve income of the smallholders.

Pair Analysis

With the rapid development of the social economy, China is suffering from severe water scarcity due to improper management. Evaluation of water resource value is a crucial issue for innovative management in regional water resources. In this paper, in consideration of the complexity and uncertainty of water resources, 15 indicators were selected to establish the assessment system for its value in Wuhan City from the following three aspects, namely the environment, resources, and society. The analytic hierarchy process (AHP) and Entropy Weight Method were combined to calculate the comprehensive weight. An improved set pair analysis (SPA) model was applied to evaluate water resource assets in the period of 2013–2017. For the sake of the dependability of these results, the James Pollution Loss model was utilized to compute loss of water resource value caused by the decline of water quality in the water pollution environment. The results show that the amount of water resource through physical quantitative accounting in Wuhan City fluctuates greatly. The initial change is relatively stable, then surges in 2015 and 2016, but slumps in 2017. The total water resource assets for Wuhan City from 2013 to 2017 are 14.221, 14.833, 28.375, 75.558, and 21.315 billion RMB, respectively. Therefore, water resource value accounting plays an indispensable role in the environmental protection and sustainable development of water, as well as provides a support for comprehensive calculation and management of various valuable natural resources.

Wuhan city is the biggest city in central China and has suffered subsidence problems in recent years because of its rapid urban construction. However, longtime and wide range monitoring of land subsidence is lacking. The causes of subsidence also require further study, such as natural conditions and human activities. We use small baseline subset (SBAS) interferometric synthetic aperture radar (InSAR) method and high-resolution RADARSAT-2 images acquired between 2015 and 2018 to derive subsidence. The SBAS-InSAR results are validated by 56 leveling benchmarks where two readings of elevation were recorded. Two natural factors (carbonate rock and soft soils) and three human factors (groundwater exploitation, subway excavation and urban construction) are investigated for their relationships with land subsidence. Results show that four major areas of subsidence are detected and the subsidence rate varies from −51.56 to 27.80 millimeters per year (mm/yr) with an average of −0.03 mm/yr. More than 83.81% of persistent scattered (PS) points obtain a standard deviation of less than −6 mm/yr, and the difference between SBAS-InSAR method and leveling data is less than 5 mm/yr. Thus, we conclude that SBAS-InSAR method with Radarsat-2 data is reliable for longtime monitoring of land subsidence covering a large area in Wuhan city. In addition, land subsidence is caused by a combination of natural conditions and human activities. Natural conditions provide a basis for subsidence and make subsidence possible. Human activities are driving factors and make subsidence happen. Moreover, subsidence information could be used in disaster prevention, urban planning, and hydrological modeling.

Cytophotometric Study

Two samples of plants of Celosia cristata, a quantitative short-day plant, were grown in an 8-h or a 16-h day. The shoot apices were collected at 11, 15, 18, and 28 days in order to carry out a cytophotometric study of the nuclear DNA in the corpus. This distribution of the DNA values was analyzed statistically using the χ2 test. At the beginning of development, for both 8-h day and 16-h day plants, the DNA content of the majority of the nuclei is at the 2C level. Then the percentage 2C–4C or 4C nuclei increases, slowly for the plants grown under a 16-h photoperiod and quickly for the others. At the 28th day, the Gaussian distribution of DNA values indicates that the state reached by the meristems is quite different. Between the 18th day and the 28th day of culture, ontogenesis of the shoot apex goes through a critical period. At the end of this period, shoot apices of the plants grown under a 16-h photoperiod are in the intermediate phase with a majority of nuclei in the synthetic phase (S) or in the postsynthetic phase (G2). Simultaneously, structural modifications of the axial zone give rise to a central zone characteristic of the fasciation of the shoot apex. In plants grown with an 8-h photoperiod, the shoot apex goes through the prefloral phase with more numerous nuclei in the presynthetic phase (G1) or in the synthetic one (S). For each sample the nuclei clustered in a particular phase of the cell cycle indicate that a certain synchronism of the cell cycles in the corpus takes place. These results are compared with those recently obtained by other authors working with different plants.
