They are cautioning the situation will get worse in the years ahead as temperature of the earth continues to rise unabated as a result of pollution of the atmosphere, deforestation, rapid urbanization and other human activities, myjoyonline.com wrote.
It is well documented that long periods of drought resulting in agric failure is negatively impacting food security all over the world but the scientists say the health implications have been equally dire.
They explain diseases like malaria, meningitis, among others are spreading quickly because of increasing temperatures.
“The increase in temperature heats the water habitat. And the mosquitoes which transmit malaria grow faster in increased temperatures. This increases the number of mosquitoes,” Edna Ototo, a medical parasitologist at the Kenyatta University in Kenya told a conference on climate change in Zanzibar — Tanzania.
Every year, an estimated 400,000 people die from malaria globally with more than 90 percent of the cases recorded in Africa.
“Increased temperatures also increase the rate of growth of the malaria parasite in the mosquito. It means the transmission will go up and then we will have an epidemic,” she added.
Edna Ototo also explained severe incidents of drought as a result of climate change is increasing malnutrition cases in Africa which is negatively impacting the health of many.
About 50 percent of all deaths in children under five are attributable to undernutrition, translating into the loss of about three million young lives a year.
“Because there is less food for women and mothers who are the most vulnerable group, there are increased diseases in children and mothers” she explained.
She said this could cause more stunted growth in Africa, and result in the development of more less intelligent children because of the absence of basic vitamins and minerals in their diets.
Wangai Ndirangu of the Jomo Kenyatta University in Kenya told the conference erratic rainfall patterns as a result of climate change is putting the lives of many at risk because of failing agriculture.
“In Eastern Africa, we are seeing increased droughts within a short period of time. We used to have seven to nine years between each drought. But now it has come up to three. This has left farmers in a cycle of poverty,” he explained.
He called for better planning to help deal with the problem.
“If you take a city like Accra, what will be the size of the population in 10 years? Then you are able to plan ahead. That capacity is important,” he noted.
Aboud Jumbe who is Head of the Policy, Planning and Research Unit at the Department of Environment in the Second Vice President’s Office in Zanzibar — Tanzania described climate change as a difficult challenge that requires a concerted effort to tackle.
“Today, climate change and marine pollution are the most pressing ‘cocktail’ of environmental problems ever to face humanity. In fact, the impacts of climate change are threatening to reverse decades of technological successes that the world fought so hard to achieve.
"These existential challenges have already forced us to invest more in securing our future while simultaneously striving for sustainable livelihoods. This is not easy,” he said.
Daniel Aghan of the journalism group Media on Environment, Science, Health and Agriculture called for more education on the impact of climate change for ordinary members of the public.
“We need to set the agenda of talking climate change and show the world what climate change is all about. We need to show how climate change is impacting right from the grassroot to the policy level,” he noted.
