Family planning is a matter of social justice

Leaders have the opportunity to unleash women's full potential.

Many leaders from government and civil society will meet in London today to discuss family planning. What they discuss will have an impact on women and girls around the world.

Today more than 25,000 girls under the age of 18 will get married, and the same number will do so tomorrow, the next day, and the next. For the majority of these girls, pregnancy and childbirth will soon follow.

Complications in pregnancy and childbirth are the leading causes of death among adolescent girls aged 15-19 in low and middle-income countries, resulting in thousands of deaths every year. That so many women die as a result of complications from pregnancy or childbirth in the 21st century is a shocking indictment of the low priority given to the needs and status of women and girls in many societies.

As well, many suffer complications in childbirth. In the case of fistula, women may be rejected by their husbands and families and outcast by their communities. They may endure intense shame and physical pain.

Access to reproductive health services is a health issue, but it is also an issue of social justice and human development. It is a basic human right for women to enjoy full legal equality and equality of opportunity, and for a girl born today, in any country, to have the same life prospects as any boy.

When women’s needs for family planning and reproductive and sexual health services go unmet, their chances of finishing their education, entering and remaining in productive work, and breaking out of poverty are sharply reduced.

All too often, women and girls are discriminated against not only in access to health services, but also in education and in the labour market — with negative repercussions for not only their own freedoms, but for progress in their countries as a whole.  In 2010, UNDP introduced the Gender Inequality Index as part of its Human Development Reports, to reveal differences in the distribution of human development achievements between women and men so that policymakers know to take steps to reduce disparities.

Empowering women and girls is one of the strongest tools available to accelerate development. Sexual and reproductive health and rights are an essential component of that empowerment.

When women have control over their health and sexuality, they can plan their pregnancy and childbirth, better protect themselves from HIV and other sexually transmitted infections, and fare better in their families, households, communities, and countries.

This summit, hosted by the UK government and the Bill & Melinda Gates Foundation, with UNFPA and other partners, could mark the start of a new drive to empower women and girls.

The Guttmacher Institute and UNFPA estimate that meeting the unmet need for modern family planning methods in developing countries would cost about $8.1 billion annually. With $4 billion of this total now being invested, there is a shortfall of $4.1 billion.

Leaders have the opportunity to help plug the $4.1 billion a year funding gap in order to get contraception to the hundreds of millions of women who would like to access family planning, but can’t.

Leaders can also take this opportunity to ensure that women’s and girls’ rights are enshrined in law, empowering them to decide whether, when, and how many children they have. 

When women can access family planning, they have the opportunity to shape their own future, and that of their children.  The benefits are felt across whole nations.

All our societies are the poorer if they fail to tap the full potential of half their population, and do not remove the obstacles to their success.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
