In the United States, it seems like we only hear about what's going wrong in Africa. We see and read stories about famine, HIV/AIDS, disease, or conflict.
In fact, few Americans will ever step foot in countries like Malawi or Zambia, largely because our media often scares people away.
As I travel across Africa, working as a senior researcher for the Worldwatch Institute as co-project director of Nourishing the Planet, I am hoping to show a different side of the continent.
Instead of stories of despair, we are looking at and sharing stories of success and hope, highlighting African-led innovations that are helping to alleviate hunger and poverty in an environmentally sustainable way.
After spending time in Lusaka meeting with non-governmental organisations, non-profits and projects on the ground, I discovered that this country is filled with incredible individuals and organisations - making my job very easy, and in many ways serving as a model for the rest of the continent.
Here are some examples:
COMACO, an organisation founded over 30 years ago to conserve local wildlife, helps farmers improve their agricultural practices in ways that can protect the environment - such as through conservation farming - while also creating a reliable market for farm products.
It organises the farmers into producer groups, encouraging them to diversify their skills by raising livestock and bees, growing organic rice, using improved irrigation and fisheries management and other practices so that they don't have to resort to poaching elephants or other wildlife.
The United Nations World Food Programme's Purchase for Progress (P4P) programme, with funding from the Bill & Melinda Gates Foundation, the Howard G. Buffett Foundation, and the Belgian government, is working with the private sector, governments and NGOs to provide an incentive for farmers to improve their crop management skills and produce high-quality food, create a market for surplus crops from small and low-income farmers and promote local processing and packaging of products.
Mobile Transactions, a financial services company for the 'unbanked' in Zambia, allows customers to use their phones like an ATM card. Over the last decade, cell-phone use in Africa has increased fivefold and farmers are using their phones to gain information about everything from markets to weather.
By using Mobile Transactions, farmers are not only able to make purchases and receive payment electronically; they are also building a credit history which can make getting loans easier.
And Mobile Transactions also works with USAID's PROFIT programme to help agribusiness agents make orders for inputs, manage stock flows and communicate more easily with agribusiness companies and farmers.
Perhaps most importantly, the partnership helps agents better understand the farmers they are working with so that they can provide the tools, inputs and education each farmer and community needs.
Care International's work in Zambia has two main goals: increase the production of staple crops and improve farmers' access to agricultural inputs such as seeds and fertilisers. But instead of giving away bags of seed and fertilisers to farmers, Care is "creating input access through a business approach", not a subsidy approach, according to Steve Power, assistant country director for Zambia.
One way they're doing this is by creating a network of agro-dealers who can sell inputs to their neighbours as well as educate them about how to use hybrid seeds, fertilisers and other inputs. At the same time, "we are mindful" of the benefits of local varieties of seeds.
Jan Nijhoff of the Common Market for Eastern and Southern Africa (COMESA) and Michigan State University, who is also an advisor on Worldwatch's Nourishing the Planet project, says COMESA's mission is to promote regional economic integration through increased co-operation and integration of trade, customs, transport, communication, technology, energy, and gender, as well as agriculture, environment and natural resources.
