Taveuni: The Garden Island
Taveuni is renowned as Fiji's "Garden Island" due to its exceptionally high rainfall and fertile volcanic soils. The eastern mountains record rainfall up to nearly 10,000 mm/year, whilst the western side is sheltered from prevailing trade winds and receives much less precipitation.
This unique microclimate creates ideal growing conditions for a variety of crops, particularly root vegetables like taro and cassava that thrive in the rich volcanic soil. The island's natural fertility has supported generations of farmers, and its lush environment, coupled with sustainable agricultural practices, offers significant potential for carbon sequestration, aligning with modern climate-smart farming objectives. Modern commercial farming requires careful management to maintain sustainability.
Rainfall Patterns on Taveuni
Based on long-term climate data for Taveuni (1961–2018), the island experiences distinct wet and dry seasons. The wet season (November–April) brings high rainfall (250–300 mm/month) with frequent rain days, while the dry season (May–October) sees lower rainfall (99–177 mm/month) and fewer rainy days, especially July–August.
Understanding these rainfall patterns is crucial for implementing climate-smart agricultural practices that enhance soil carbon sequestration, contributing to significant carbon offsetting benefits for the project and broader environmental sustainability.
Seasonal Overview
Wet Season (November–April)
High rainfall (250–300 mm/month)
Frequent rain days (12-18 days per month)
Ideal for planting root crops
Risk of cyclones, especially January-March
Dry Season (May–October)
Lower rainfall (99–177 mm/month)

Understanding these seasonal patterns is crucial for planning planting schedules, irrigation needs, and field operations throughout the year.
Effective seasonal planning also offers opportunities to implement carbon-smart farming practices, contributing to carbon offsetting goals through enhanced soil health and sustainable land management.
Soil Types in Taveuni
Taveuni is characterised by rich volcanic soils, notably Vitric Andosols and Humic Andosols, especially in the south. These soils feature high organic matter, available phosphorus, and potassium, with slightly acidic pH levels (approximately 5.5–6).
According to soil surveys, approximately 53% of land is Typic Hydrandepts, with other portions classified as Typic Dystrandepts, Hydric Dystrandepts, and Udic Eutrandepts. These volcanic soils provide excellent growing conditions but require careful management to maintain their fertility.
Furthermore, the high organic matter content characteristic of these soils is crucial for carbon sequestration, turning the farm into a significant carbon sink. This natural ability to store atmospheric carbon can contribute to carbon offsetting initiatives, adding an environmental benefit to sustainable farming practices in Taveuni.
Soil Fertility Challenges

Soil fertility is declining in many taro-growing areas across Taveuni. Nitrogen, phosphorus, and potassium levels are often insufficient or imbalanced, and soil testing is rarely performed by farmers.
Declining Nutrients
Intensive farming without proper nutrient management has led to decreasing levels of essential nutrients in many fields.
Insufficient Testing
Most farmers do not conduct regular soil testing, leading to improper fertilisation practices and further soil degradation.
Acidification
Continuous cropping without proper pH management has led to increasing soil acidity in many areas.
Missed Carbon Opportunities
Poor soil management practices mean missed opportunities for carbon sequestration, reducing the land's potential for climate resilience and carbon offsetting benefits.
Soil Improvement Priorities
Boost Labile Carbon
Increase organic matter inputs through compost, mulch, and cover crops to improve soil structure and microbial activity, contributing to carbon sequestration and potential offsetting benefits.
Improve Soil pH
Adjust soil pH to above 5.6 using appropriate amendments like agricultural lime to optimise nutrient availability.
Use Cover Crops
Implement cover crops like Mucuna pruriens to fix nitrogen, prevent erosion, and add organic matter to the soil.
Increase Organic Inputs
Add compost, manure, and other organic amendments to improve yields and reduce disease incidence.
Optimal Planting Windows
These planting windows are optimised based on crop moisture needs and Taveuni's unique rainfall patterns. Adjustments may be needed based on specific field conditions and microclimate variations across the island.

Carbon Offsetting Benefits
Implementing these optimal planting windows, especially for crops and cover crops that enhance soil health and organic matter, directly contributes to carbon sequestration. Healthy soils act as carbon sinks, helping to offset emissions and align with sustainable agriculture goals.
Taro (Dalo) Cultivation
Planting Guidelines
  • Ideal planting period: November to April
  • Prefers months with >250 mm rainfall

Planning Your 100-Acre Farm
Land Assessment
Evaluate soil types, topography, drainage patterns, and accessibility across your property.
Zone Planning
Divide land into crop-specific zones based on soil suitability, water access, and operational efficiency.
Seasonal Calendar
Create a detailed planting and harvesting schedule aligned with Taveuni's rainfall patterns.
Infrastructure Development
Plan access roads, drainage systems, irrigation, and post-harvest facilities to support operations.
Carbon Offsetting
Integrate carbon sequestration practices and explore opportunities for carbon credits to enhance sustainability and revenue.
Implementation
Execute your plan in phases, starting with the most suitable areas and expanding gradually.
Land Planning & Layout
Effective land planning is crucial for a successful 100-acre operation. Consider these key factors when dividing and rotating plots:
  • Water flow and natural drainage patterns
  • Soil types and fertility zones
  • Access for machinery and transport
  • Buffer zones between crops
  • Windbreaks and erosion control
  • Opportunities for carbon sequestration through agroforestry or sustainable soil practices.
Create dedicated lanes for machinery to minimise soil compaction across the entire field. Establish permanent drainage systems in areas prone to waterlogging, especially for taro cultivation. Integrating land use strategies that promote carbon offsetting can provide long-term environmental and financial benefits.
Crop Rotation & Intercropping
Taro (Dalo)
Heavy feeder, requires nutrient-rich soil. Plant in the most fertile areas first.
Legume Cover Crop
Follow taro with Mucuna or other legumes to fix nitrogen, rebuild soil structure, and increase soil organic carbon content.
Cassava (Tavioka)
More tolerant of lower fertility, can follow legumes in the rotation, benefiting from improved soil health.
Vegetables
Grow short-cycle vegetables before returning to cover crops or fallow, leveraging residual nutrients.
This rotation cycle helps maintain soil fertility, break pest and disease cycles, and maximise land productivity over time. Crucially, it also enhances soil carbon sequestration, contributing to your farm's carbon offsetting benefits and overall sustainability. Adjust the sequence based on your specific soil conditions and market demands.
Intercropping Strategies
Intercropping involves growing two or more crops in proximity to maximise space and resources. Effective combinations for Taveuni include:
  • Taro + beans or peas (legumes fix nitrogen that benefits taro)
  • Cassava + pumpkin (pumpkin provides ground cover, reducing weeds)
  • Taro + bele (at field edges, utilising different growing heights)
  • Cassava + chili (complementary root and above-ground space utilisation)
When intercropping, ensure that companion plants have compatible water and nutrient needs, and that one crop doesn't shade the other excessively.
Beyond yield optimisation, effective intercropping strategies also play a crucial role in carbon sequestration. By fostering increased plant biomass and enhancing soil organic matter, intercropping contributes to the absorption and storage of atmospheric carbon, thereby supporting climate-smart agricultural practices and offering potential for carbon offsetting.
Climate-Smart Adjustments
Cyclone Preparedness
Taveuni faces increasing cyclone risks during the wet season (November-April). Implement these measures:
  • Plant windbreaks around vulnerable fields
  • Establish robust drainage systems to handle heavy rainfall
  • Stagger planting dates to reduce total crop exposure
  • Have emergency harvest plans for mature crops when cyclones threaten
Drought Resilience
Prepare for extended dry periods, especially during July-September:
  • Implement water harvesting systems during wet months
  • Use mulch extensively to retain soil moisture
  • Install efficient irrigation systems where feasible
  • Select drought-tolerant varieties for planting in drier zones
Carbon Offsetting Benefits
Integrate practices that sequester carbon for environmental and economic benefits:
  • Utilise agroforestry to enhance carbon capture in trees and soil
  • Incorporate biochar to improve soil health and store carbon
  • Implement cover cropping to boost soil organic matter and sequester CO2
  • Explore opportunities for carbon credit programmes to generate additional revenue
Seasonal Rainfall and Risk Overlay
This chart overlays Taveuni's monthly rainfall patterns with key risk periods. The cyclone season (November-April) coincides with the wet season, while moisture stress is most likely during July-September. Understanding these patterns is essential for planning planting schedules, irrigation needs, and risk management strategies.
Strategic Planning for Carbon Gains
Aligning farm activities with Taveuni's seasonal rainfall and risk patterns allows for optimised carbon offsetting. For example, implementing soil health practices before the heavy rains or staggering planting to manage cyclone risk can enhance the long-term carbon sequestration potential of your 100-acre farm.
Enhanced Soil Carbon Sequestration
During the drier months of July-September, applying biochar and increasing soil organic matter through composting can significantly improve soil water retention, fostering robust microbial activity that sequesters carbon. During the wet season, healthy, carbon-rich soils are more resilient to erosion, preventing carbon loss.
Optimised Resource Use & Reduced Emissions
Efficient water management during the July-September dry spell, such as drip irrigation or rainwater harvesting, minimises energy consumption for pumping. Similarly, adapting planting schedules to avoid peak wet season heavy machinery use reduces fuel emissions. These practices directly contribute to lowering the farm's greenhouse gas footprint.
Agroforestry for Climate Mitigation
Integrating resilient tree species and perennial crops (agroforestry) provides critical windbreaks during the November-April cyclone season, protecting annual crops and preventing soil erosion. These systems also act as significant carbon sinks, absorbing atmospheric CO2 year-round and building deep soil carbon pools, particularly effective in Taveuni's fertile volcanic soils.
Building Climate Resilience with Co-Benefits
Strategies like cultivating drought-tolerant taro varieties for the dry season or improving drainage for cassava fields during the wet season not only build climate resilience but also support carbon offsetting. Healthier, more adaptable ecosystems are inherently better at absorbing and storing carbon, creating a virtuous cycle of sustainable farming.
Soil Health & Amendments
Testing Your Soil
Regular soil testing is essential for maintaining optimal fertility. Take 15-20 soil cores per 5-10 acres, at 0-20 cm depth, and mix into a composite sample per field zone. Send samples to a certified lab such as SPC-CePACT in Nadi for comprehensive analysis.
Key Parameters to Test
  • pH (aim for 5.8-6.5 for most crops)
  • Organic matter percentage
  • Nitrogen, phosphorus, and potassium levels
  • Calcium and magnesium
  • Micronutrients (zinc, boron, manganese)
Implementing advanced soil health practices and strategic amendments offers significant benefits beyond crop yield and fertility. These methods actively enhance the soil's capacity to sequester atmospheric carbon, turning agricultural land into a valuable carbon sink. This opens up opportunities for carbon offsetting, contributing to environmental sustainability and potentially generating new revenue streams through certified carbon credits. Effective monitoring and verification are crucial to realising these benefits.
Soil Amendment Recommendations
pH Adjustment
For soils with pH below 5.0: Apply 1.5-2 tonnes of agricultural lime (CaCO₃) per acre
For pH 5.0-5.5: Apply 1-1.5 tonnes of dolomitic lime per acre (adds magnesium)
For pH 5.6-6.0: Monitor and apply 0.5-1 tonne if needed
Nitrogen Management
For low nitrogen: Apply 60-90 kg N total per season using urea (46% N) or chicken manure
Organic option: Apply 5 tonnes compost plus Mucuna cover crop
Split urea application: 50% at planting, 50% 4-6 weeks later
Organic Matter Boost
For low organic matter (<2.5%): Apply 3-5 tonnes of local compost per acre
Alternative: Apply 1 tonne biochar mixed with 2 tonnes manure
Cover crops: Plant Mucuna or Sunn hemp at 30-40 kg seed per acre
Carbon Sequestration & Offsetting
Practices like applying compost and biochar, along with planting cover crops, significantly enhance soil carbon sequestration. This directly contributes to carbon offsetting, improving environmental sustainability and potentially qualifying for carbon credits.
Increased soil organic carbon (SOC) leads to healthier soil, reduced fertiliser needs, and improved water retention, offering both ecological and economic benefits.
Composting for Farm Sustainability
Creating your own compost is a cost-effective way to improve soil health and reduce dependency on imported fertilisers. Establish a dedicated composting area on your farm to process:
  • Crop residues from harvests
  • Prunings from windbreaks and border plants
  • Animal manure (if available)
  • Food processing waste
Furthermore, composting plays a crucial role in carbon sequestration, enriching soil with stable organic matter that locks away atmospheric carbon. By reducing reliance on synthetic fertilisers and diverting organic waste from landfills, it also significantly lowers the farm's greenhouse gas emissions, contributing to climate change mitigation efforts.
Turn compost piles regularly to maintain aerobic conditions and speed decomposition. In Taveuni's climate, compost can be ready in 3-4 months with proper management. Apply finished compost before planting or as a side dressing for established crops.
Biochar: A Carbon-Smart Amendment
Biochar is a form of charcoal produced by burning organic material in a low-oxygen environment. It offers multiple benefits for Taveuni's agricultural systems:
  • Carbon sequestration (stable for hundreds of years)
  • Improved water retention in soil
  • Enhanced nutrient holding capacity
  • Habitat for beneficial soil microorganisms
  • Potential for carbon offsetting and earning carbon credits through long-term carbon storage.
For best results, "charge" biochar by mixing it with compost or manure before application. This allows it to absorb nutrients that will be slowly released to crops over time. The stable carbon in biochar can be quantified, potentially allowing the farm to participate in carbon credit markets, further enhancing sustainability and financial viability.
Cover Crops for Soil Regeneration
Beyond their immediate agricultural benefits, cover crops play a crucial role in carbon offsetting by enhancing soil organic matter, which effectively sequesters atmospheric carbon dioxide. This contributes to a more sustainable and climate-resilient farming system.
Mucuna pruriens (Velvet Bean)

  • Capturing and storing rainwater during wet periods for use in dry spells
  • Implementing contour planting and swales to slow water movement across fields
  • Creating efficient drainage systems to prevent waterlogging during heavy rains
  • Using mulch extensively to reduce evaporation and maintain soil moisture
  • Installing drip irrigation in areas prone to drought or for high-value crops
Irrigation Systems for Dry Periods
Drip Irrigation
Most water-efficient system that delivers moisture directly to plant roots. Ideal for vegetables and high-value crops. Requires filtration to prevent clogging and regular maintenance.
Sprinkler Systems
Covers larger areas but less water-efficient than drip. Useful for establishing cover crops or during extreme dry periods. Best operated in early morning or evening to reduce evaporation.
Rainwater Harvesting
Collect rainwater from roofs and other surfaces into storage tanks. Essential for sustainable water management. Size storage based on dry season length and crop water requirements.
Carbon Offsetting through Efficiency
Efficient irrigation reduces energy consumption for pumping and contributes to healthier soils. Practices like rainwater harvesting and precise drip irrigation minimise your farm's carbon footprint, supporting broader environmental sustainability and potential carbon offsetting initiatives.
Drainage Solutions for Wet Periods
Surface Drains
Shallow channels that collect and direct excess surface water away from crops. Particularly important for taro, which is susceptible to waterlogging. By preventing waterlogging, surface drains help maintain aerobic soil conditions, reducing greenhouse gas emissions and supporting healthy microbial activity for carbon sequestration. Maintain regularly to prevent blockages.
Raised Beds
Elevate planting areas above the general field level to improve drainage around root zones. Essential for vegetables and beneficial for most crops during extremely wet periods. Raised beds improve soil aeration, fostering a healthier soil microbiome that can enhance carbon storage and reduce nutrient leaching.
Swales on Contour
Ditches dug along contour lines that slow water movement and allow infiltration. Combine with berms to create effective water management systems across sloped land. Swales prevent soil erosion and promote water infiltration, significantly contributing to soil organic carbon buildup and enhancing the farm's resilience to climate change.
Subsurface Drainage

Furthermore, these digital tools are increasingly vital for tracking and demonstrating the carbon offsetting benefits of sustainable farming practices. They enable precise data collection on soil carbon sequestration, reduced emissions from fertiliser use, and efficient resource management, providing the necessary verifiable data for carbon credit markets and sustainability reporting.
Even in areas with limited connectivity, many tools offer offline functionality with later synchronisation when internet access is available.
Value-Added Processing
Taro Chips
Convert lower-grade taro into shelf-stable, high-value chips. Requires slicing equipment, fryers, packaging machinery, and quality control systems. Popular in both local and export markets.
Frozen Cassava
Process and freeze cassava for longer shelf life and easier export. Requires washing, peeling, cutting, blanching, freezing, and packaging facilities. Popular with diaspora communities abroad.
Dried Vegetables
Convert surplus vegetables into dried products with long shelf life. Can use solar dryers for energy efficiency. Creates market opportunities during glut periods and reduces waste.
Beyond economic gains, value-added processing significantly contributes to carbon offsetting efforts. By transforming raw produce into finished goods, we reduce post-harvest waste, which minimises methane emissions from decomposition. Local processing also reduces transportation emissions compared to exporting raw materials, further lowering the carbon footprint of our agricultural activities. Implementing energy-efficient processing methods, like solar drying, can further enhance these environmental benefits and align with broader sustainability goals.
Certification Opportunities
Organic Certification
Verify farming practices meet organic standards through recognised certifying bodies. Provides access to premium markets and prices. Requires detailed record keeping and regular inspections.
Fair Trade Certification
Demonstrate commitment to fair labour practices and community development. Appeals to socially conscious consumers. Requires adherence to specific labour and pricing standards.
Carbon Credits
Unlock new revenue streams by sequestering carbon on your farm. This offsets emissions for buyers, enhances your sustainability profile, and contributes to climate action. Requires robust monitoring and verification for certification.
Training and Capacity Building
Investing in training for both farm managers and workers is essential for long-term success. Key areas for capacity building include:
  • Sustainable farming techniques specific to Taveuni conditions
  • Pest and disease identification and management
  • Soil health assessment and improvement
  • Post-harvest handling and quality control
  • Record keeping and farm management
  • Carbon offsetting strategies and their associated benefits
Connect with organisations like Teitei Taveuni, SPC, PIFON, or ACIAR-led programmes that offer training materials and field trials relevant to your context, including emerging areas like carbon smart farming.
