The benefits of regular food speak for themselves. But the effects of the food production group have been more wide-ranging than this. Tenneh speaks of the huge difference working in a group has made to her. Acting together, the farmers can share their skills and work more efficiently. As she tells us, the bottom line is that 'the group work provides more food'.

Tenneh speaks of the support and the encouragement that the farmers give to each other, and how much can be achieved when the community comes together. 'What inspires me in life is unity,' she says. 'To me, unity means coming together to decide on one thing and take that forward.'

Now that they are no longer limited by hunger, the people of Gbap (pronounced Bap) have come together and successfully lobbied for a new school and an agricultural work centre for the community. The people of Gbap have taken their future into their own hands.

During Christian Aid Week, 15,000 churches across Britain and Ireland will organise house-to-house collections and events to raise funds to enable organisations like MCSL to carry out their work transforming communities such as Gbap. Christian Aid currently works with 507 partners in 47 countries in Africa, Asia, the Middle East, Latin America and the Caribbean, helping people to make change happen. Our donations will be multiplied many times over as many small actions come together to make a huge change. But the giving that takes place during Christian Aid Week is not oneway.

Unity is something that our churches are not always good at, and the value of community that has inspired Tenneh is something that we can learn from and be changed by. Christian Aid Week is about raising funds. But it is also a call to unity - an invitation for churches to come together and celebrate the possibility of hope and life in parts of the world where mere survival can be a struggle.

This is a challenge, because division and inequality and injustice will always be easier than unity. But Tenneh's insistence that remarkable things can happen when we come together is not new. We see it in the actions and ministry of Jesus, who pushed against all that leads to violence and separation and called his disciples to model a new way of community.

Can we use this Christian Aid Week to allow ourselves to be changed? If we can work together, with each other, with our churches and with our neighbours both at home and as far away as Gbap, then we may start to see huge change happen.

Tenneh says that 'when you are a group and work with focus and total commitment, you work at a faster rate; the stronger ones can help with work that weaker ones cannot do by themselves'. As we engage in Christian Aid Week, we can rejoice as we stand together in solidarity. Although we might ask who is the strong and who is the weak - and who is actually giving to whom.

Be a part of Christian Aid Week this year: if, together, we take small actions we can give people like Tenneh the tools to make big change happen.

£6.50 could buy a set of four hand tools for a farmer living in the town of Gbap; £50 could pay for advocacy training for two young people in a Kenyan slum, equipping them with the tools they need to pressure their government to provide essential services; £123 could buy a reclaimed aluminium greenhouse for women working on market gardening projects in Tajikistan, providing a vital tool for growing vegetables in a harsh climate experiencing extremes of hot and cold.
