What is Terrace Farming? Everything You Need to Know

Terrace farming is one of the most widely used and old agricultural practice used to cultivate crops on hilly or sloped terrain. It is formed as a preventive measure against soil erosion. Farmers in hilly regions create step-like flat surfaces, or terraces, to reduce soil erosion, retain water, and maximise arable land. This method, is also commonly seen in regions like Southeast Asia and the Andes, and has allowed communities to grow staple crops like rice, wheat, and barley on challenging landscapes for centuries.

In addition to improving farming conditions in hilly areas, terrace farming also enhances irrigation efficiency and promotes sustainable agriculture, making it a vital practice in many parts of the world. Let’s dive deeper into the benefits, techniques, and impact of terrace farming.

Terrace farming is a traditional agricultural technique that dates back thousands of years, originating in ancient civilizations such as the Incas in South America and the Chinese in East Asia. It was developed as a way to farm mountainous or sloped terrain by creating flat, levelled steps or surfaces, or “terraces,” into the hillsides which were often not available in hilly regions. These terraces allowed farmers to cultivate crops on otherwise unusable land while controlling water flow and minimising soil erosion and loss or nutrition-rich soil. The ingenuity of this technique not only transformed steep landscapes into productive fields but also helped support large populations.

The importance of terrace farming lies in its ability to sustainably manage water and soil resources in difficult terrains. By slowing down water runoff and reducing soil loss, terrace farming has been vital for agriculture in regions where flat land is scarce making growing food difficult. This method has enabled communities around the world to grow crops such as rice, wheat, and maize, making it a critical tool for food security, particularly in rural, hilly areas.

How Terrace Farming Works

We know that agriculture is done on flat beds of land where walking, sowing seeds, and watering and harvesting are easy. But what about the people who settled in hilly terrains? They came up with Terrace farming.

Terrace farming involves converting sloped land into a series of step-like flat surfaces, or terraces, each supported by a restraining wall. These terraces are constructed horizontally along the silhouette lines of the slope, preventing water from rushing down too quickly, which would otherwise cause erosion of the soil and loss of crops. These levelled sections slow down water flow, allowing it to soak into the soil and irrigate crops more efficiently. Farmers also typically build drainage channels or bunds between terraces to manage excess water and ensure even distribution across the steps to avoid overwatering of the land as well.

Once these terraces are built, the process of farming is similar to flat-land agriculture. Crops are planted on flat surfaces, where the soil is protected from erosion and water is conserved. The structure of the terraces also helps with temperature regulation, as the stepped design allows for better absorption of sunlight. This method is especially effective in regions with heavy rainfall, as it mitigates the risk of flooding while ensuring that the crops receive adequate water for growth.

Most Common Types of Terraces in Terrace Farming

Terrace farming varies in design depending on the landscape, climate, and type of crops being cultivated. Over the years, realising the different geographies that the hilly terrains bring along with them, various kinds of terrace farming techniques were developed. These new types of techniques have helped ensure maximum efficiency in preventing soil erosion and conserving water. Here are the most common types of terraces used in agriculture:

Bench Terraces: Horizontal steps with vertical or slightly sloped walls that provide flat surfaces for crop growth. These kind of terraces look like benches that are used for writing or designing.
Graded Terraces: Slightly sloped terraces designed to control the flow of water and direct it to desired areas. These very smarties ensure water reaches all corners of the farm.
Contour Terraces: Built along the natural contours of the land to follow the slope’s shape, reducing soil erosion. This is much like contouring concept in makeup.
Riser Terraces: Terraces with steep walls or risers between each step, often used on very steep terrain, and high hilly regions.
Stone Wall Terraces: These use stones as retaining walls to hold back soil and water, common in rocky or arid regions.
Channel Terraces: Designed with a drainage channel between terraces to manage excess water, ideal for areas with heavy rainfall.

Different Terrace Farming Systems

Terrace farming has emerged as a popular solution for growing food in urban areas with limited space. By utilising flat platforms or terraces created on sloped land, this method maximises land usage and allows for efficient cultivation in both rural and urban settings. Over the years, this has proven to not only be a great way to produce fresh food in cities but also help manage water runoff and prevent soil erosion.

Here are some of the most commonly used terrace farming systems in the hilly regions across India.

Step Terracing: In this system, farmers create a series of flat steps or terraces, perfect for growing crops on sloped land while minimizing soil erosion and water loss.
Bench Terracing: As mentioned before, wide, levelled platforms are constructed, suitable for large-scale cultivation, where crops can be planted in rows across the terrace. This gives water enough slope but at the same time also does not let to much water runoff.
Riser Terracing: The focus is on building steep risers between the flat terraces, typically used in hilly regions with steep slopes to reduce water runoff and erosion.
Retaining Wall Terracing: Walls made of stone, wood, or other materials are constructed to hold the soil in place on each terrace, providing strong support and preventing erosion.

Vertical Gardens: Most recently becoming one of the common styles of urban buildings, malls, and indoor plantations. This type of planting system requires vertical terraces where stacked planters or green walls are created to grow food, maximising space in densely populated areas.

Pot and Container Terrace Farming: This flexible system uses pots or containers to grow plants on flat rooftops, balconies, or terraced platforms, allowing for easy management of individual plants. Each of these terrace farming systems can be adapted to various climates, soil types, and available space, making it a versatile solution for urban agriculture and sustainable farming.

Benefits of Terrace Farming for Agriculture

We have been looking at how terrace farming has been helping farmers situated in hilly regions grow and pursue agriculture. We have understood that by creating flat areas on otherwise sloping terrain, it enables the cultivation of crops that would otherwise be difficult to grow. This method not only improves land usability but also offers numerous environmental and economic benefits.

Here are some of the key benefits of terrace farming:

Prevents Soil Erosion: The flat surfaces reduce the speed of water runoff, which helps prevent soil from being washed away, maintaining soil fertility and structure. Soil erosion i a major issue in regular flat land regions as well, and terrace farming is a brilliant solution to counter the issue.
Water Conservation: Terracing allows water to seep into the soil more effectively, reducing the need for irrigation and conserving water resources in dry regions.
Increases Arable Land: By transforming steep slopes into usable farmland, terrace farming makes previously inaccessible or unproductive land suitable for agriculture.
Enhances Crop Yields: The method improves soil quality and water management, leading to healthier crops and potentially higher yields.
Reduces Flooding and Water Runoff: Terraces slow down the flow of water, which helps to prevent floods and control water drainage in hilly areas.
Supports Sustainable Agriculture: Terrace farming promotes eco-friendly farming practices, as it minimizes land degradation and encourages the efficient use of resources.

These benefits make terrace farming an essential practice in regions where traditional farming methods may not be feasible, supporting both small-scale farmers and larger agricultural efforts.

What Is the Purpose of Terrace Farming?

We have now understood that terrace farming is primarily designed to enable agriculture on sloped or hilly terrains, where traditional farming methods are less effective and might face geographical challenges. By creating stepped, flat platforms along the slope, this method allows farmers to cultivate crops in areas where the natural topography would otherwise prevent efficient farming. It also serves as a crucial tool in managing environmental factors like soil erosion and water conservation.

The main purposes of terrace farming include:

Maximizing Land Usability: The main purpose of terrace farming is that it transforms unusable slopes into arable land, allowing farmers to grow crops in difficult terrains. Hilly regions face food shortages, especially in the colder seasons but terrace farming allows the farmers to grow food in their region to avoid facing such shortages and make food available even in winter seasons
Preventing Soil Erosion: The terraces act as barriers, slowing water flow and preventing the soil from being washed away. This ensures that hilly regions are not left barren and can be still used as places of settlement.

Improving Water Management: By controlling water runoff, terrace farming helps in retaining water within the soil, reducing the need for external irrigation. This also helps farmers repurpose water for other household activities since that is also a scarce resource there.

How to Start Terrace Farming?

Are you someone who lives in hilly regions and would like to pursure Terrace farming. It can be an excellent way to utilise sloped land or rooftops for growing crops, even in urban environments. Starting terrace farming requires proper planning, site preparation, and the right approach to soil and water management. With the right steps, you can transform unused or difficult terrain into productive agricultural land.

Here’s how to start terrace farming:

Evaluate the Site: Assess the slope, sunlight exposure, and water drainage of the land or rooftop to determine its suitability for terrace farming. Sometimes in hilly regions, some regions might not receive enough sunlight because it is blocked by hills.
Design the Terrace Layout: Plan the number, width, and height of the terraces based on the slope and space available. Make sure to follow the natural contour of the land. For better water drainage make sure to follow the terrain in the natural form best way possible.
Prepare the Soil: Add rich organic matter or compost to improve soil fertility. You may need to import topsoil depending on the condition of the existing soil and also make sure that the depth achieved in enough.
Construct the Terraces: Build the terraces by creating level steps on the slope. Use retaining walls made of stones, wood, or concrete to hold the soil in place and prevent erosion. Also ensure that there is still enough place for plants to grow.
Install Proper Drainage: Ensure adequate drainage by designing outlets for excess water. Contour terracing will help control runoff and water retention.
Plant Crops: Select appropriate crops that are suited to the climate, soil type, and water availability. Space the plants efficiently for better yield. Some crops need mushy lands where as some grow in arrid lands as well. Choose what best fits your land.
Maintain the Terraces: Regularly check for soil erosion, repair walls if needed, and continue improving soil health through composting and mulching.

By following these steps, you can create a productive terrace farming system that maximizes the potential of sloped land or rooftops for sustainable crop production.
