S&RI puts drones over your fields, solar on your roof, and hard data behind your decisions. We work with farmers, business owners, and organizations across Guyana who are done waiting for the right time to modernize.
Each arm of S&RI solves a different problem. Some of our clients use one. Others use all four. Here's the short version.
Your field is too large to walk and too important to guess about. Our drones map it, spray it, and hand you the data â processed and ready to act on.
Rooftop systems for your house. Commercial arrays for your warehouse. Solar street lights for your community. One team handles the design, equipment, and installation.
Floods, erosion, rising sea levels â Guyana's coast is under pressure. We help organizations and government agencies plan for what's coming, not just react to what already happened.
We publish what we learn. Sustainability reporting, drone field trials, soil science, energy policy â the kind of sector analysis that agribusinesses and policymakers can actually use.
A drone covers in twenty minutes what takes a crew days on foot. We fly it, process the data, and hand you a clear picture of what your land actually needs.
We fly multispectral cameras over your fields and stitch together high-resolution maps that show crop stress, drainage issues, and vegetation gaps you can't spot from the ground.
Fertilizer and pesticide go exactly where they're needed â not across the entire field. Farmers who switch to drone spraying typically cut chemical use by a third while hitting the target more consistently.
Want your own team handling the flights? We run certified training that covers navigation, payload management, safety protocols, and maintenance â so you don't depend on us forever.
Raw drone imagery on its own is just photos. We run it through ArcGIS to produce soil maps, vegetation indices, and spatial datasets your agronomist or manager can act on directly.
Not sure which service fits? We come to you first. A site visit lets us assess your acreage, identify the right drone setup, and quote you based on what your farm actually looks like â not a generic price list.
Panels above, crops below. Agrivoltaic setups let you generate electricity on the same land you farm â particularly useful for shade-tolerant crops and livestock pastures where dual use makes economic sense.
Guyana sits in one of the highest solar irradiation zones on earth. If you're still paying full price for grid electricity â or running a generator â that's money the sun could be saving you.
Grid-tied panels sized for your household or small business. The system feeds excess power back to the grid, and your meter runs in reverse during peak sun hours.
Warehouses, processing plants, offices, cold storage â if your monthly electricity bill makes you wince, a commercial array pays for itself faster than most capital equipment.
Standalone units that charge during the day and light roads, housing schemes, car parks, and public areas at night. No trenching, no wiring to the grid, no recurring electricity cost.
Remote farms, construction camps, research stations, disaster response â anywhere GPL doesn't reach or can't be relied on. Battery-backed systems that run independently.
Before a single panel goes up, we model your roof or ground mount in 3D â checking shadow patterns, structural loads, and irradiation angles so the system is sized right the first time.
Not everyone pays upfront. We offer financing plans matched to your energy usage and available space, so the monthly payment stays below what you'd have spent on electricity anyway.
Most locations in Guyana receive 4.5 to 5.5 peak sun hours daily â well above the threshold where solar becomes the cheapest source of electricity. With equipment costs falling and local demand rising, installations that seemed expensive five years ago now pay back in under four.
Guyana's coastal plain sits below sea level. Floods cost farmers entire harvests. Businesses lose inventory. Communities lose years of progress in a single wet season. We help organizations plan ahead â with data, not hope.
Most planning looks backwards. Foresight looks at what's plausible ten, twenty, thirty years out â and works backwards from there. We use MICMAC to identify which variables will matter most, MACTOR to map who controls what, and ArcGIS to lay it all across real geography. Our team applied these same tools to research battery energy storage adoption in Delhi, and we bring that cross-sector rigour to infrastructure and agricultural planning in the Caribbean. The output isn't a prediction. It's a set of structured scenarios your board or ministry can actually plan against.
Concrete seawalls crack. Mangroves adapt. The most effective coastal defences in Guyana combine both â green-grey infrastructure that pairs mangrove belts and coastal grasses with engineered structures. This isn't theoretical: the GGGI-led IRIS programme is already developing integrated drainage and irrigation strategy across six coastal regions, and a separate KFS-funded initiative is restoring mangroves along a 6 km stretch of shoreline. We draw on these methodologies to design site-specific resilience plans for farms, estates, and coastal businesses.
When floodwater reaches your property, the question isn't whether you planned â it's whether you planned well enough. We work with organizations to build flood management strategies that align with Guyana's Low Carbon Development Strategy 2030: ranking infrastructure vulnerabilities, sequencing capital investments, setting up monitoring systems that flag problems before they become emergencies. The goal is institutional readiness â not just a plan on a shelf, but a system your people know how to operate.
Most consultancies hand you a report and move on. We put our findings in the open â so the sector benefits, not just our clients.
How do you measure the environmental footprint of a rice farm? What ESG metrics make sense for a 50-acre operation in Region 5? This paper builds a reporting framework that works at the farm level â not just for corporations with compliance departments.
Field trials comparing drone-surveyed versus manually inspected plots across rice, sugar cane, and mixed farming systems. The data shows where UAVs save time and money, and where they don't â because not every problem needs a drone.
Guyana mills produce thousands of tonnes of rice husk annually, and most of it is burned or dumped. This study tests its viability as a soil amendment â measuring nutrient release, water retention, and yield response against conventional synthetic inputs.
A whitepaper explaining why we built Tech4Agri, how the service model works, and what it would take to scale drone-as-a-service across Guyana's farming regions. Written for agribusiness managers and policy planners, not engineers.
Climate finance is real money â but it flows to organizations that can demonstrate measurable impact. This brief makes the case that farms which adopt sustainability reporting early will have a direct advantage in accessing green credit lines and premium export markets.
We started S&RI in 2025 because we kept seeing the same gap: technical work that stays inside reports, and farmers and businesses left figuring things out alone. Between us â Dr. Vairaj Arjune and Dr. Krishna Tripathi â we've spent over fifteen years studying water systems, energy policy, and climate adaptation across six Caribbean countries, India, and Southeast Asia. Vairaj currently leads national flood resilience and mangrove restoration programmes at GGGI Guyana. Krishna's doctoral research tackled the hard question of how energy storage systems get adopted in developing economies. We built this company to take what we know from research and intergovernmental work and put it directly into the hands of the people who grow food, run businesses, and manage communities.

Vairaj holds a PhD in Science Policy from Jawaharlal Nehru University and has worked in water and environmental management across the Caribbean since 2012. As National Adaptation Officer at GGGI, he leads two active programmes: the IRIS-funded National Drainage & Irrigation Strategy covering six coastal regions, and the KFS Coastal Resilience Programme overseeing 6 km of mangrove restoration. His fieldwork spans thirteen institutions across Guyana, Barbados, Jamaica, Antigua and Barbuda, Belize, and Dominica. He is an ICSSR Doctoral Fellow and ICCR Commonwealth Scholar.
Co-Founder & Technical Lead
Krishna earned her PhD at JNU, where she spent seven years researching how energy storage systems and electric mobility get adopted in developing economies â work that required her to bridge engineering data with policy analysis and stakeholder behaviour. She holds an Advanced CDPM certification from PM4DEV, an ICSSR Doctoral Fellowship, and has published in Technological Forecasting and Social Change. At S&RI, she leads the technical research portfolio and sustainable finance advisory.
Our work is designed around the Caribbean's specific constraints â small markets, limited data infrastructure, high climate exposure, and institutional systems that move at their own pace.
We've conducted fieldwork across thirteen institutions in Guyana, Barbados, Jamaica, Antigua and Barbuda, Belize, and Dominica. We know how decisions get made in this region â and where they stall.
Peer-reviewed journals, international conferences at Globelics and 4S, and operational project delivery for GGGI. We don't just study problems â we build the systems that address them.
