Reimagine waste jackfruit

NXplorers students in Sri Ramakrishna High School, India, reimagined the use of waste jackfruit to develop an energy solution that would create an economic alternative for farmers, and lead to a cleaner, greener environment.

Up to 40 per cent of the food produced in India is either lost or wasted*. Even though India is the largest jackfruit producer in the world, only a small amount is used. Most of the fruit is left to ripen and spoil. Not only does this cause a lot of food wastage, it means that farmers make less money, and it also has a negative effect on health as the rotting fruit increases the risk of diseases spread by mosquitos.

The NXplorers students came up with the idea to reimagine waste jackfruit as an alternative fuel and rethink waste in their communities. Their idea was firmly rooted in driving a sustainable change that would support farmers to switch to an eco-friendly fuel option. These are the steps they followed…

Reconsider Traditional Methods

Neha started by gathering information about the traditional methods used for spraying, which commonly included using Gator pumps. When she analysed and evaluated her findings, she concluded that Gator pumps could not control pressure and output properly. Moreover, these methods consumed a significant amount of time, labour and fuel. Reverting to a traditional method would therefore make spraying crops more difficult and time consuming for farmers.

Redesign Something New

With the help of her school teachers and NXplorers mentors, Neha applied the NXplorers Scenario Planning tools to consider the positive and negative features of different scenarios to help identify a preferred future. After extensive research and experimenting, she developed an automatic Agri Sprayer to maximise effectiveness and minimise manual effort from the farmer. The various mechanical components of the sprayer meant that the crop treatment could be more targeted and easily distributed, which reduced both health risks and labour costs. As well as being easy to use, it also consumed less fuel and produced less noise.

Rethink Pesticide Practices

Since development, Neha has continued to test the idea by using a working prototype in her family owned farms. The new sprayer has proved to be more effective than existing sprayers and has maximised the crop yield. Importantly, it has saved time for farmers and protected their health, improving the wellbeing of the local farming community overall. Looking to the future, Neha intends to make the sprayer widely available to betel nut farmers across India.

Neha’s problem-solving innovation is not only creating sustainable agricultural practices, but also promoting good health and wellbeing and building resilience for her local farming community. The innovation therefore contributes to several UN SDGs, including 3 and 9.

3. Good health and well-being
Ensure healthy lives and promote well-being for all at all ages

9. Industry, innovation and infrastructure
Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation

Diagram of the United Nations’ Sustainable Development Goals numbered in a large circle, each with a smaller diagram below to represent the specific Development Goal. All of the Development Goals are faded, apart from two of them:

3. Good health and well-being
9. Industry, innovation and infrastructure

Within the circle there are three circles in a triangle formation reading ‘Energy’, ‘Water’ and ‘Food’, with arrows to show how they are all interconnected.
