Bangladesh Agriculture Sector
Bangladesh has experienced consistent economic growth, with GDP growth ranging from 6% to 7% annually. Agriculture, which covers 70% of the country’s land, faces land loss, declining soil fertility, and salinization challenges. The pressure from urban and peri-urban expansion has decreased cropland area, with land being double-cropped in most areas. Rice is the dominant crop, followed by wheat, maize, jute, and vegetables. The country has achieved food security, with grain production tripling between 1972 and 2014.
However, challenges like limited access to high-quality foods and climate impacts continue to affect vulnerable populations. Bangladesh climate change, with increased risks from sea level rise, salinization, changing rainfall patterns, and extreme weather events. The agriculture sector, responsible for 39% of the country’s greenhouse gas emissions, remains the main source of emissions. However, the country needs help in societal dimensions, such as low Social Progress Index (SPI) scores and limited decision-making power.

Types of Greenhouses in Bangladesh
Bangladesh uses Different greenhouses for agricultural purposes, including polyethylene film-covered, shade net, and naturally ventilated options. Polyethylene film-covered greenhouses are cost-effective and easy to construct, providing insulation and temperature regulation. Shade net greenhouses use shade netting to control sunlight intensity, protect crops from heat, and reduce water evaporation.
Naturally ventilated greenhouses rely on natural airflow for temperature regulation, with strategically placed openings or vents. Frames are typically made of locally available materials like bamboo, wood, or steel, with the choice based on factors like cost, durability, and availability.
Greenhouse Farming Techniques in Bangladesh
Greenhouse farming techniques in Bangladesh have witnessed significant advancements, as highlighted in a study focusing on vegetable and floriculture production in the country. Using different greenhouse farming techniques in Bangladesh, including protected cultivation, polyhouse systems, and low-cost tunnels.
These techniques enable farmers to create a controlled environment that optimizes crop growth and protects plants from adverse weather conditions, pests, and diseases. Protected cultivation involves using structures such as greenhouses, tunnels, or net houses to shield crops from external factors. This technique enhances crop quality, extends the growing season, and ensures higher yields by providing favorable conditions for plant growth.
Polyhouse systems, another widely used technique, employ structures covered with polyethylene films to create a controlled environment. These structures offer insulation, regulate temperature and humidity, and protect crops from external elements. Low-cost tunnels, on the other hand, provide an affordable option for small-scale farmers. These structures are typically constructed using locally available materials like bamboo, plastic sheets, or nets.
Low-cost tunnels protect crops while allowing for ventilation and maintaining favorable growing conditions. Adopting innovative techniques like drip irrigation, fertigation, and integrated pest management (IPM) in greenhouse farming. Drip irrigation ensures efficient water usage, fertigation combines irrigation with fertilization, and IPM focuses on eco-friendly pest control methods, reducing the reliance on chemical pesticides.
Sustainable Practices in Bangladesh Greenhouse Farming
Sustainable practices in greenhouse farming in Bangladesh are gaining popularity as farmers aim to minimize environmental impact while ensuring long-term productivity. Key practices include using organic fertilizers and biopesticides, conserving water resources through drip irrigation and rainwater harvesting, encouraging crop rotation and diversification, implementing integrated pest management (IPM) strategies, implementing energy-efficient technologies like solar-powered ventilation systems, and focusing on waste management.
