Feeding my family:  Feeding my family How small scale farmers cope with climate change Slide2:  Having enough food to eat throughout the year is important for all of us. This is known as food security. We all know how important it is to have a varied diet. In some parts of the world, some people do not have enough food to eat. Food security In the UK, there is plenty of food available. Most of us buy our food from the supermarket or local markets. What food do we rely on?:  What food do we rely on? It is amazing, but we rely on just 20 different types of plants for all of our food. Maize, rice, wheat and potatoes are the most common food crops. It is dangerous to only rely on these few crops for all our food needs. Climate change could effect how well these foods grow. There are many traditional food crops that only grow in a few places. Changing climates and food security:  Changing climates and food security With changing climates, farmers face many challenges Drought Floods Warmer temperatures Extreme weather – hurricanes Farmers (and plants) need to adapt to the new climates to ensure their crops grow well.

Grow a range of crops – if one dies another may survive the new climate. Grow local varieties of crops that are adapted to the local climate. Growing a range of crops that are suitable for a changing climate helps to make sure that food is in good supply. Save seed from one harvest to plant the following year. Slide7:  Why choose local seed and plants? Non-traditional or high-yielding varieties of plant are bred to produce large amounts of the edible part e.g. fruit, potatoes or grains. These type of plants require a lot of water and fertiliser. This is expensive for the farmer but they get large crops in return. Farmers can grow fewer plants to produce the same amount of food. Local varieties of plant are adapted to the local climate. They will grow, even in extreme climates. They can help to provide food in a changing climate.
