With
up to one billion undernourished people around the world. Globally,
more than 2 billion people suffer from a deficiency of micronutrients
such as iron, zinc, and vitamin A essential for the functioning of
human bodies and agriculture and land use systems increasingly
vulnerable to climate change and land degradation change is of an
urgency.
Droughts caused by global warming could devastate up to 60%
of the world's wheat fields by the end of the century, causing food
shortages and instability, researchers warned. The world must prepare
for "unprecedented" shocks to the production of the crop.
Wheat, a key ingredient in everyday staples such as bread, noodles
and cereals, provides nearly a fifth of calories consumed by humans
globally. Even if the world manages to limit warming to 2 degrees
Celsius (3.6 F), the negative effects would still double between 2041
and 2070, they said, urging farmers to adapt by using water more
efficiently and altering planting schedules. Africa
would be the most affected region by the middle of the century, Petr
Havlik, one of the authors, told the Thomson Reuters Foundation.Africa is not a major wheat producer, but the crop provides 14% of
the calories consumed by the continent's population.
Europe,
the United States and Russia would also be severely hit, said Havlik,
deputy director at Austria's International Institute for Applied
Systems Analysis.
Swapping
fish for meat to help combat climate change risks exacerbating hunger
in Africa, from where fish is increasingly exported to wealthy
nations instead of providing key vitamins to malnourished local
people, experts warned. popular fish such as sardines and mackerel
are sourced from African countries that export most of their
nutrient-rich catch instead of selling it to their own populations,
said a paper published in the journal Nature.
Some
consumers in rich countries are shunning meat in favour of other
forms of protein, including lentils and fish, in order to reduce the
amount of planet-warming greenhouse gases emitted by intensive
livestock farming. A shift in diets would
"serve to ... worsen the food and nutritional security of
already vulnerable people in places such as West Africa, Asia and the
Pacific", said Christina Hicks, the paper's lead author.
Globally,
fish consumption is at an all-time high of 20.2 kg (44.5 lb) per
person. The global fishing industry is
worth $166 billion, and much of the fish on supermarket shelves in
Europe and China comes from developing countries such as Namibia and
Kiribati, which can export more than 90% of their fish catch.
The
study found that across much of the tropics, especially in
sub-Saharan Africa, some of the most nutritious species of fish such
as anchovies are found in countries where citizens suffer from a lack
of essential vitamins and minerals.
Yet
"foreign fishing, illegal fishing, subsidies, prices, and trade
all act to divert much-needed nutrients away from those in need,"said Hicks, a professor at Britain's Lancaster University.
In
Namibia, almost the entire population is estimated not to have an
adequate intake of vitamin A, while in Mauritania, the same applies
to nearly half of its people.
Even
a small portion of the catch from their waters could go a long way
towards combating malnutrition-related diseases in millions of people
within 100 km (60 miles) of the sea, Hicks said.
One
way forward is to reform international fishing policies so local
governments require companies to divert a small portion of their
catch into programmes for malnourished children, Hicks said.
In
Mauritania, for example, foreign fishing makes up over 70% of the
fish caught, much of which are highly nutritious species but are
processed in-country to be used in aquaculture abroad, she said.
Countries
could replicate projects under way in Bangladesh and Uganda where
fish heads, bones and tails that are usually binned by factories are
turned into fish powder that can be added to meals to boost
nutrition, Hicks said.
Charlotte
Ersboll, U.N. Global Compact Senior Advisor, citing a recent study by
the organisation.
“It’s
very clear that despite all the excitement around SDGs it’s really
very superficial what companies are doing.” She said that only 27
percent of companies where carrying sustainability through their
supply chain.
Director
General of the Food and Agriculture Organisation of the United
Nations (FAO), Qu Dongyu called on the food industry to do more to
support healthy foods and reduce food loss and waste.
Columbia
University professor and Sustainable Development Solutions Network
Director, Jeffrey Sachs, said, We know that agriculture is pushing
against ecosystems all over the world to an absolutely shocking
extent. ”We’re losing the ecosystem…” He explained, “We
will not get sustainability on the planet, unless there’s
co-responsibility,” he said. “We’re going to lose the
resilience of the food sector itself if climate change, loss of
biodiversity, destruction of land, scarcity of water continues the
direction we’re going.”
Scarlett
Benson, Associate presented the report “Growing Better: Ten
Critical Transitions to Transform Food and Land Use”.
“If
we continue as we’re going, we’re going to deforest 400 million
more hectares of natural ecosystem for agricultural land,” Benson
said. “But if we can implement this reform agenda, we’ll actually
save 1.2 billion hectares of land that is currently used for
agriculture and that land will be available for return to nature so
that will allow us to…achieve all biodiversity agenda.” She
mentioned the part of the research that often garners a lot of
attention is about freeing up land.
“Because
freeing up land, by changing our diets, by reducing food loss and
weight and including agriculture productivity through better use of
technology, actually enables us to use land more efficiently,”
Benson said. “Land
has an opportunity cost and it is an asset for us,” she said.
