AGRICULTURE
Crop yield potential has reduced in Kenya for all major crops. Since the 1960s, crop yield potential in Kenya has reduced by 6.4% for maize, 1.5% for winter wheat, 1.1% for spring wheat, and 15% for rice. PHOTO C. de Bode/CGIAR
HEALTH
The WHO African region spends the lowest in health adaptation at USD0.45 per capita (compared to USD5.50 per capita in the Americas and USD5 per capita in Europe). Kenya is even below the African average at USD0.26 per capita. PHOTO A. Habtamu/ILRI
EXTREME TEMPERATURES
In Kenya, 86 million potential labour hours were lost due to heat exposure on average in 2015–2018. This is a 5-fold increase from the average for 2000–2003. 98% of the lost hours were lost in the agricultural sector. PHOTO C. de Bode/CGIAR
EMISSIONS
Africa still produces 50% of its electricity from coal, although this is down from 70% in the 90s. In 2016, only 2.6% of electricity in Africa was generated from renewable sources. PHOTO Anagoria
DROUGHT
Major recurring droughts in the Horn of Africa have affected tens of millions of people and cost billions of dollars in livestock losses, particularly in the arid and semi-arid lands that occupy 80–90% of Kenya’s land area. PHOTO K. Dhanji/ILRI
The life of every child born today will be profoundly affected by climate change, with populations around the world increasingly facing extremes of weather, food and water insecurity, changing patterns of infectious disease, and a less certain future. Without accelerated intervention, this new era will come to define the health of people at every stage of their lives.
'Children are particularly vulnerable to the health risks of a changing climate. Their bodies and immune systems are still developing, leaving them more susceptible to disease and environmental pollutants,' says Nick Watts, executive director of The Lancet Countdown. 'The damage done in early childhood is persistent and pervasive, with health consequences lasting for a lifetime. Without immediate action from all countries to cut greenhouse gas emissions, gains in wellbeing and life expectancy will be compromised, and climate change will come to define the health of an entire generation.'
A second path – which limits the global average temperature rise to 'well below 2ºC' – is possible, and would transform the health of a child born today for the better, throughout their lives. Placing health at the centre of the coming transition will yield enormous dividends for the public and the economy, with cleaner air, safer cities, and healthier diets.
However, the United Nations warns that we are on the brink of missing the opportunity to limit global warming to 1.5°C:
If we rely only on the current climate commitments of the Paris Agreement, temperatures can be expected to rise to 3.2°C this century. Temperatures have already increased 1.1°C, leaving families, homes and communities devastated.
We need to close the ‘commitment’ gap between what we say we will do and what we need to do to prevent dangerous levels of climate change. Governments cannot afford to wait. People and families cannot afford to wait. Economies must shift to a decarbonization pathway now.
Bold new approaches to policy making, research and business are needed in order to change course. An unprecedented challenge demands an unprecedented response. It will take the work of the 7.5 billion people currently alive to ensure that the health of a child born today is not defined by a changing climate.
The Lancet Countdown authors call for bold action to turn the tide on the enormous health impact of climate change in four key areas:
- Delivering rapid, urgent, and complete phase-out of coal-fired power worldwide.
- Ensuring high-income countries meet international climate finance commitments of USD100 billion a year by 2020 to help low-income countries.
- Increasing accessible, affordable, efficient public and active transport systems, particularly walking and cycling, such as the creation of cycle lanes and cycle hire or purchase schemes.
- Making major investments in health system adaptation to ensure health damage of climate change doesn’t overwhelm the capacity of emergency and health services to treat patients.

Director general, International Livestock Research Institute (ILRI)
We are delighted that ILRI was able to help The Lancet Countdown in its vital work of advancing the discussion on climate change. It is especially gratifying that ILRI is at the forefront of efforts to find solutions for the livestock sector under climate change that incorporate the perspectives and well-being of people in the developing world

We are not seeing the sort of change that we need, and I’m concerned that children in Africa will suffer as a result.
Rosemary Sang
Scientist, Kenya Medical Research Institute (KEMRI)
Past and current economic activities in the West are likely to affect Africa’s future for decades to come. We cannot afford to wait on the sidelines for the right decisions to be made; we must lend our voices to those calling for urgent action now.
Nick Watts
Executive director, Lancet Countdown
With its high rates of healthcare inequality, poverty, and food insecurity, the health effects of climate change are going to be felt strongly across Africa. Dengue and Malaria will spread into new areas, a more hostile climate will continue to threaten food security, and without immediate action, climate change will come to define the health of an entire generation.
