A systematic review of the role of integrated farming and the participation of universities in ensuring food security: Malaysia's effort.

Food security is critical for promoting health and well-being and achieving sustainable development, especially in developing countries. Despite the recent efforts to improve it, food security is still a concern due to the rapid increase in populations, conflicts, and natural disasters worldwide. Universities, particularly agricultural universities, play an essential role in addressing food security issues by researching, developing new technologies, and providing education and training to farmers and other stakeholders. The main objective of this review is to discuss the role of universities and integrated farming in ensuring food security, specifically in Malaysia. It includes a brief overview of the different types of integrated farming methods that can be used to improve food security and finally discusses the Student Farmer Entrepreneur program, which can be crucial for promoting food security by increasing agricultural productivity, promoting local food production, encouraging sustainable agriculture practices, and supporting rural development. This review also considers the significant impact of the Malaysian government and universities on food security. With integrated farming and the Student Farmer Entrepreneur program, food security can be further improved.

Evaluation of quality and hydrogeochemistry of rock aquifers in Jurong Formation at Southern Johor Bahru, Malaysia.

Jurong Formation underlies part of Southern Johor Bahru which comprises well cemented and consolidated volcanic-sedimentary rocks. The study aims to assess quality and hydrogeochemistry of rock aquifer in Jurong Formation at Southern Johor Bahru which is mainly overlain by rhyolitic tuff. It also evaluates the differences in quality and hydrogeochemistry of rhyolitic tuff aquifer found in source and floodplain zones of South-West Johor Rivers Basin. In this study, a total of nine samples from four wells, namely TW1-TW4, were collected at foothills of Gunung Pulai (TW1) and Iskandar Puteri (TW2-TW4) in Southern Johor Bahru. The samples were examined for physiochemical parameters. The groundwater in the study area is fresh and non-saline with hardness of soft to hard. The pH of groundwater in source zone is significantly higher than in floodplain zone. Meanwhile, the hardness of groundwater in source zone is significantly lower than in other deep wells in floodplain zone as more calcite mineral is present. The concentration of manganese, iron and zinc is lower at source zone than floodplain zone. Three facies of water types were encountered during the study such as CaNaHCO3 in TW2, CaHCO3 in TW1 and TW3 and CaCl2 in TW4. The deep wells in floodplain zone are susceptible to saline intrusion. Finally, the groundwater quality in the study area is found to control by rock weathering especially silicates and carbonates, rainfall and proximity to seawater. This suggests the major control on groundwater chemistry is due to leaching of volcanic rocks and dissolution on calcite infillings. In conclusion, the groundwater is clean and safe in general although pH value is slightly acidic closer to straits and magnesium's presence in higher concentration at TW2.

Integrated models for solid waste management in tourism regions: Langkawi Island, Malaysia.

The population growth, changing consumption patterns, and rapid urbanization contribute significantly to the growing volumes of solid waste that are generated in urban settings. As the rate of urbanization increases, demand on the services of solid waste management increases. The rapid urban growth in Langkawi Island, Malaysia, combined with the increasing rates of solid waste production has provided evidence that the traditional solid waste management practices, particularly the methods of waste collection and disposal, are inefficient and quite nonsustainable. Accordingly, municipal managers and planners in Langkawi need to look for and adopt a model for solid waste management that emphasizes an efficient and sustainable management of solid wastes in Langkawi Island. This study presents the current practices of solid waste management in Langkawi Island, describes the composition of the solid waste generated in that area, and presents views of local residents and tourist on issues related to solid waste management like the aesthetic value of the island environment. The most important issue of this paper is that it is the first time that integrated solid waste management is investigated in the Langkawi Island.
