With the intensification of global climate change, agricultural production faces numerous challenges, especially in tropical regions like Malaysia, where climate uncertainty increasingly impacts agriculture. Greenhouses, as a modern agricultural solution, aim to provide a controlled growing environment, enhancing crop growth efficiency and yield. However, despite the clear advantages of greenhouses in climate adaptation and agricultural production, Malaysia still faces multiple challenges in their application.
High Construction and Maintenance Costs
Building and maintaining greenhouses require significant financial investment. For many small-scale farmers, the high initial investment can be a barrier to technology adoption. Even with government support and subsidies, many farmers remain cautious about investing in greenhouses, fearing long cost recovery periods. In this context, controlling costs is crucial for those looking to invest in greenhouse construction. These costs include the price of the greenhouse and subsequent maintenance costs. Only with low maintenance costs can the payback period be shortened; otherwise, it will be prolonged.
Lack of Technical Knowledge
Effective management of greenhouses requires a certain level of agricultural technical knowledge, including climate control, pest management, and scientific use of water resources. Many farmers, due to a lack of necessary training and education, are unable to fully utilize the technical advantages of greenhouses. Additionally, without proper technical support, climate control and crop maintenance within the greenhouse may encounter issues, affecting production outcomes. Therefore, learning agricultural technical knowledge related to greenhouses and mastering the temperature, humidity, and light required for crop growth are essential to maximize the use of greenhouses.
Extreme Climate Conditions
Although greenhouses can mitigate the impact of external environments on crops, Malaysia’s unique climate conditions, such as high temperatures, high humidity, and heavy rainfall, still pose challenges to greenhouse production. Extreme weather events can make it difficult to control temperature and humidity within the greenhouse, affecting crop health. Malaysia’s temperatures range from 23°C to 33°C throughout the year, rarely dropping below 21°C or rising above 35°C. Additionally, annual rainfall ranges from 1500mm to 2500mm, with high humidity. The high temperature and humidity in Malaysia indeed present a challenge in greenhouse design. How to optimize design while addressing cost issues is a topic that greenhouse designers and manufacturers need to continue researching.
Limited Resources
Water resource distribution in Malaysia is uneven, with significant differences in freshwater availability across regions. Greenhouses require a stable and continuous water supply, but in some resource-scarce areas, water acquisition and management can pose challenges to agricultural production. Additionally, nutrient management is a crucial issue, and the lack of effective organic or soilless cultivation techniques can affect crop growth. In addressing water resource limitations, China has developed relatively mature technologies, such as integrated water and fertilizer management and water-saving irrigation. These techniques can maximize water use while providing precise irrigation based on the different growth stages of crops.
Market Access and Sales Channels
Although greenhouses can improve crop quality, accessing markets and establishing stable sales channels remain significant challenges for small farmers. If the cultivated agricultural products cannot be sold in time, it may lead to surplus and losses. Therefore, building a stable market network and logistics system is crucial for the successful application of greenhouses.
Insufficient Policy Support
Although the Malaysian government has introduced policies to support modern agriculture to some extent, the coverage and depth of these policies need to be strengthened. Some farmers may not receive the necessary support, including financing, technical training, and market promotion, limiting the widespread adoption of greenhouses.
Data Support
According to the latest data, Malaysia’s agricultural employment population is approximately 1.387 million. However, the number of farmers using greenhouses is relatively small, mainly concentrated in large agricultural enterprises and government-supported projects. While specific data on greenhouse users is not clear, it is anticipated that this number will gradually increase with the promotion of technology and policy support.
Conclusion
The application of greenhouses in Malaysia offers new opportunities for agricultural production, particularly in climate adaptation and improving production efficiency. However, facing high costs, lack of technical knowledge, extreme climate conditions, and market access challenges, the government, enterprises, and related institutions need to work together to promote the sustainable development of greenhouses. This includes enhancing farmer education and training, improving policy support, promoting technological innovation, and building market infrastructure, ultimately achieving stable and efficient agricultural production.
