Greenhouses have become integral to modern agriculture in Lâm Đồng, with their area expanding from 1,170 hectares in 2004 to nearly 5,688.5 hectares by recent estimates. This growth underscores their crucial role in enhancing agricultural productivity and resilience against climate change.
Evolution of Greenhouse Cultivation
Since their introduction in Đà Lạt around 1994, greenhouses have progressively replaced traditional outdoor farming methods. The increase in greenhouse area in three distinct periods—2004-2010, 2011-2015, and 2016-2020—reflects their growing importance in local agriculture. These structures not only protect crops but also optimize resource use, contributing significantly to the province’s economy.
Challenges in Greenhouse Management
Despite their benefits, the lack of standardized construction, assembly specifications, and building density regulations hampers sustainable development. Currently, 65.5% of greenhouses are self-built or assembled by local farmers, emphasizing the need for unified guidelines to ensure structural integrity and environmental harmony.
Leveraging High-Tech Solutions
Greenhouses are pivotal in deploying advanced agricultural technologies such as IoT-enabled smart solutions, automated controls, solar energy utilization, and LED lighting. These innovations not only enhance productivity but also mitigate environmental impacts, crucial in adapting to climate change challenges.
Economic Impact and Potential
The economic value of greenhouse production in Lâm Đồng is significant, with average yields reaching 600 million VND per hectare annually for vegetables and up to 1.5 billion VND for flowers. The integration of IoT technologies has further boosted revenues to 2 billion VND per hectare for vegetables and 3-5 billion VND for flowers, showcasing the potential for high-value agricultural outputs.
As greenhouse cultivation continues to expand in Lâm Đồng province, establishing technical standards and regulatory frameworks is imperative. Guided by comprehensive guidelines from the Ministry of Agriculture and Rural Development, these standards will ensure sustainable growth, harmonize landscape integration, and optimize agricultural production efficiency.
