> Reduce food loss and waste affect the environment due to the unsustainable use of natural resources, the generation of waste, and GHG emissions.

> Maximize transparency in the supply chain, communicating safety and quality, providing reassurance to consumers while alerting both retailers and manufacturers to food identified as unsafe. It also helps increase local food availability, which positively impacts people's health and nutrition.

The lack of technification of certain farmers will not allow them to make certificates of origin or good practices, displacing them.

Unnecessary use of pesticides to ensure sanitary regulations and quality measures.

Information that will be shared semi-publicly or publicly, giving anyone the power to view data.

Execution risk: > Despite blockchain in other technologies such as bitcoin, its use in other software platforms is limited, including interoperability challenges. An analytical solution can be first implemented to test for digital adoption and generate benefits. > Investment: Implementing software tracking solutions can be expensive and time-consuming.

Stakeholder participation risk: > It is necessary to coordinate all supply chain participants (farmers, manufacturers, distributors) to record transactions to strengthen food management, safety, and food quality.

Drop off risk: > Taking into account that it requires coordination between the actors present in the supply chain, it may be that based on the participation of other actors, specific stakeholders could not comply or set aside the information record for noticing a lack of commitment from others.

External risk: > Having less food waste doesn't necessarily translate into solving the challenge of universal access to food, or having traceability does not necessarily translate into better prices.

Unexpected impact risk: > There could exist obstacles or reasons why a participant in the supply chain cannot participate, weakening others' initiative.

Gender inequality and/or marginalization risk: > Both rural women and indigenous communities may not have the necessary knowledge or technical education.

This initiative intends to allow supply chain participants to trace food origin and characteristics for waste reduction and income increase.

(National Development Plan (2018 – 2022)): Aims to reduce food losses and waste. Currently, 34% of total food is lost as well as the number of households in which at least one of its members did not consume all three meals one or more days in the week (21).

(National Policy for the Integral Management of Solid Waste): Seeks to implement the integral management of solid waste to contribute to the promotion of the circular economy, sustainable development, adaptation, and mitigation to climate change. The preceding through the promotion of a citizen culture, an institutional environment conducive to coordination and improvement in the reporting and monitoring of waste (27).

(National Strategy for Circular Economy): Encourages producers, suppliers, and consumers to develop and implement new business models that incorporate waste management and efficient handling materials (30).

Financial incentives: FINAGRO and Banco Agrario present financing alternatives for producers that present productive projects to increase productivity and reduce losses and food waste (25). Yunus Social Business has invested in companies such as S4S Technologies, that reduce waste in the agro level (13), but also in companies such as Campo Vivo that integrate all the agricultural chain from production to commercialization (14).

Other incentives: The waste produced from the agricultural sector can be reused as sources of bioenergy, for which some companies use these wastes. One of the examples is the Cali bioenergy cluster, which has 2,891 companies (28).

(Draft Law 301 of 2018): Policy to prevent food loss and waste, which prohibits throwing away food fit for consumption, promotes donating this food to non-profit organizations (22).

(Law 1990 of 2019): Aims to prevent the waste of food fit for human consumption and prohibits the destruction of food that cannot be marketed. The CISAN will be in charge of executing the provisions of the standard (23).

(Resolution 2184 of 2019): MinAmbiente and MinVivienda developed a resolution to established a unified color code for the separation of waste at the source. This resolution included the green color to indicate where usable organic waste, such as food scraps, agricultural waste, and others, should go (24).

Food Cloud is a food traceability app and marketplace that connects food stores with products about to expire with charities (26). Spoiler Alert is a software platform to manage sales and donation processes for excess food inventory that received USD$ 2.7M in investment (16). ""The Other Bar"" a chocolate bar designed in Ecuador, has generated a positive impact on the sale price and, therefore, on the producers' income.

Colombia hosted the 1st LatAm Summit on Food Loss and Waste (2019), organized by FAO, IDB, and DNP, where 200 delegates from the Government, the food industry, and academia participated (1).

In Cali, there is an initiative for a bioenergy cluster made up of companies that generate energy and biofuels from biomass. There are currently 2,891 companies distributed in 9 parts of the production chain: distillers, power generators, agricultural machinery, transport and logistics, fertilizers, energy distributors, and research centers. This initiative was co-financed by CAF and is accompanied by the Valle government (26).
