Environmental sustainability is central to agricultural practices in Seychelles, where protecting natural resources, conserving biodiversity, and minimizing environmental impact are key priorities. The Seychelles Planning Authority (SPA) has established guidelines under the Physical Planning (Land Use and Development Plans) Regulations 2023 (SI 90 2023) to ensure agricultural projects operate sustainably, support soil health, water conservation, and wildlife protection, while aligning with the country’s environmental goals. This article explores the sustainable practices and environmental guidelines required for agriculture development in Seychelles, from soil conservation to waste management.
Soil Conservation and Erosion Control
Healthy soil is essential for successful agriculture and environmental sustainability. SPA’s guidelines promote soil conservation techniques that protect against erosion, enhance soil fertility, and support long-term productivity in agricultural zones.
Soil Conservation Techniques:
Contour Plowing: In areas with sloped terrain, contour plowing involves tilling along the natural contours of the land, which slows water runoff and prevents soil erosion. This technique is effective for minimizing soil loss and reducing the risk of landslides during heavy rains.
Cover Cropping: Planting cover crops, such as legumes or grasses, during off-seasons helps prevent soil erosion, improves soil fertility, and reduces the need for chemical fertilizers. Cover crops also promote biodiversity by attracting beneficial insects and supporting soil health.
Reduced Tillage: Minimizing tillage, or disturbing the soil as little as possible, helps maintain soil structure and prevent erosion. Reduced tillage retains organic matter in the soil, enhances moisture retention, and reduces compaction, making it particularly suitable for conserving soil in agricultural areas.
Terracing: For farms on steep slopes, terracing involves creating stepped, level areas that prevent runoff and soil erosion. This technique is commonly used in agroforestry zones and helps increase usable land for farming while protecting soil.

By following these soil conservation practices, farmers contribute to long-term soil health and land productivity, supporting sustainable agriculture in Seychelles.
Water Conservation and Efficient Irrigation
With limited freshwater resources, water conservation is critical for agriculture in Seychelles. SPA encourages farmers to implement efficient irrigation systems and water management techniques that conserve water, reduce waste, and protect local water bodies from pollution.
Key Water Conservation Practices:
Drip Irrigation: Drip irrigation delivers water directly to the roots of plants, minimizing evaporation and runoff. This technique is highly efficient and suitable for a wide range of crops, ensuring that water is used effectively.
Rainwater Harvesting: Collecting and storing rainwater provides an alternative water source for irrigation, reducing the strain on freshwater supplies. Rainwater harvesting systems capture rainwater from rooftops or other surfaces and store it for dry periods, supporting water availability year-round.
Mulching: Applying mulch, such as straw, leaves, or compost, to the soil surface helps retain soil moisture, reduce evaporation, and suppress weeds. Mulching also enhances soil health by adding organic matter, making it a simple and effective method for conserving water in agriculture.
Soil Moisture Monitoring: Using soil moisture sensors allows farmers to monitor water levels in the soil, ensuring that crops receive adequate hydration without over-watering. This practice optimizes irrigation, conserving water and promoting healthier crop growth.

Implementing these water conservation techniques ensures that agricultural projects in Seychelles use water resources sustainably, supporting long-term agricultural productivity and resilience.
Integrated Pest Management and Agrochemical Control
Minimizing the use of chemical pesticides and fertilizers is essential to protect soil, water, and biodiversity. SPA promotes Integrated Pest Management (IPM) and safe agrochemical practices to manage pests effectively while reducing environmental risks.
Integrated Pest Management (IPM) Techniques:
Biological Control: Using natural predators, such as ladybugs for aphids, reduces pest populations without relying on chemical pesticides. Biological control supports biodiversity and is a sustainable approach to managing pests in agricultural zones.
Crop Rotation: Changing the crops grown in a field each season helps break pest and disease cycles, reducing the need for pesticides. Crop rotation also improves soil health by varying nutrient demands on the soil.
Physical Barriers: Installing physical barriers, such as netting or row covers, protects crops from pests without chemical treatments. These barriers are particularly useful for small-scale farms and help reduce the need for pesticides.
Selective Pesticide Use: When chemical pesticides are necessary, farmers are encouraged to use them selectively and according to best practices. Applying pesticides only to affected areas and using targeted products minimizes environmental contamination and preserves beneficial insects.

Environmental Benefit
Biological Control
Uses natural predators to control pest populations
Reduces reliance on chemical pesticides
Crop Rotation
Alternates crops each season to disrupt pest cycles
Improves soil health, minimizes pest outbreaks
Physical Barriers
Uses netting or covers to protect crops
Reduces pesticide use, protects crops
Selective Pesticide Use
Applies chemicals only as needed in specific areas
Minimizes environmental impact of pesticides
Adopting IPM practices helps protect Seychelles’ ecosystems, supports soil and water health, and promotes sustainable agricultural production.
Waste Management and Organic Fertilizers
Proper waste management is essential in agriculture to prevent pollution and make use of organic waste as a resource. SPA encourages farmers to implement waste reduction and recycling practices, as well as to use organic fertilizers that enrich soil health and reduce reliance on synthetic chemicals.
Sustainable Waste Management Practices:
Composting Organic Waste: Composting organic farm waste, such as crop residues, food scraps, and manure, produces nutrient-rich compost that can be used as fertilizer. This reduces landfill waste and improves soil health, providing a natural alternative to chemical fertilizers.
Manure Management: Properly storing and treating animal manure prevents water contamination and allows it to be used as an organic fertilizer. Manure is an effective soil conditioner that provides essential nutrients for crops, supporting sustainable agriculture.
Green Manure and Cover Crops: Planting cover crops, known as green manure, and allowing them to decompose adds organic matter and nutrients to the soil. This practice reduces the need for chemical fertilizers, enhances soil structure, and supports biodiversity.
Recycling Agricultural Plastics: Agricultural plastics, such as drip irrigation tubing and greenhouse covers, should be recycled or reused whenever possible. SPA encourages farmers to minimize plastic use and adopt biodegradable alternatives to reduce plastic waste.
