Crowd Sourced Demand and Fulfilment Platform for Small Scale Urban Farmers using Blockchain

This project addresses a critical challenge in developing nations: connecting small-scale urban farmers directly with consumers to improve access to fresh produce while reducing supply chain inefficiencies. By leveraging blockchain technology, the system creates a transparent, secure marketplace that eliminates intermediaries and ensures fair pricing.

Reduced Waste: More efficient matching of supply and demand

The platform demonstrates how blockchain technology can be applied to real-world problems in developing economies, creating a more efficient and equitable marketplace for agricultural products while improving food security and farmer livelihoods.
While current limitations include regulatory uncertainties around cryptocurrency and technical complexity for non-technical users, the prototype establishes a foundation for a scalable solution that could significantly impact local agricultural economies.

Agriculture, Technology
and Society.
•Technological advancements have made agriculture
more efficient and scalable, and thus support growing
populations and modern economics.
•There are concerns about the nutritional value of
farm produce.
•Rapid urbanization in developing nations challenges
traditional agricultural supply chains.
•Traditional supply chains have inefficiencies and
affect the affordability of fresh produce.

Agriculture: The Backbone of Human
Civilization. Earliest trace to 9500BC!

Comparison
State of food supply in developed vs developing nations of the world
Developed Nations
•Developed countries have an abundant food supply
with high nutritional standards and variety.
•They experience low hunger rates and high food
security.
•Access to a wide range of food options is easy due to
advanced agricultural infrastructure.
•There is strong government support and subsidies for
agriculture.
•Despite high levels of food waste, technological
integration in farming is widespread, ensuring stable
and affordable food prices.
Developing Nations
•Developing countries have a limited food supply and
often low nutritional quality and variety.
•They experience high hunger rates and low food
security.
•Access to food is limited, especially in rural areas, due
to poor agricultural infrastructure.
•Government support and subsidies for agriculture are
weak.
•There is low use of technology in farming, leading to
volatile and often unaffordable food prices, despite
lower food waste but higher post-harvest losses.

The Problem
One in four people experiences food insecurity, even in modern times.
Up to 30% post-harvest loss occurs in total
agricultural production
•735 million people globally experienced hunger (2022).
•2.4 billion faced moderate to severe food insecurity.
•Urban population to grow by 1.2 billion between 2020 and
2050, mainly in Asia and Africa.
•Several issues : fragmented land-holdings, limited farming
techniques, logistical inefficiencies, and inadequate market access.
•Urban areas have limited access to nutritious food due to supply
chain inefficiencies, leading to poverty and
malnutrition.

Objectives
Design and test a blockchain-based open
platform for buying and selling agricultural
products and groceries.
Create a transparent, crowdsourced platform to
market produce from small-scale urban farmers in
cities.

Walmart: Partnered with IBM to create a blockchain-based food traceability
system that tracks the origin and movement of products from farm to store.
Carrefour: Implemented a blockchain-based system to provide consumers with
transparent information about the origin and quality of its products.
AgriDigital: An Australian company developed a blockchain-based platform
that enables farmers to sell their grain directly to buyers, eliminating intermediaries
and reducing transaction costs.
Telangana Government (India): Partnered with a blockchain
startup to create a platform connecting farmers directly with consumers, ensuring
fair prices for farmers and reducing food waste.
FarmRaise: A crowdsourcing platform created to help farmers access funding
and resources by connecting them with a network of investors and supporters.
