This two and a half hour show is about comedian Mark Thomas's attempt to walk the entire length of the Israeli barrier in the West Bank, using the wall as a route map.

If you had asked Thomas what he was doing in Israel, he would have responded that he was writing a book "about birds and flowers". This was the line used to placate Israeli soldiers en route.

The Heretic by Richard Bean centres on Dr Diane Cassell, a specialist in sea levels, whose observations lead her to question anthropogenic climate change. As its title suggests, the play argues that belief in climate change is a religion, whereas scientists "don't believe in anything".

Woody Sez could be categorised as a jukebox musical. But, unlike We Will Rock You or Mamma Mia, there's no glitz or glamour. Refreshingly, there are no microphones or belting voices, just the intimate experience of four musicians messing about on a dozen or so instruments and singing through the hard times of the life of Woody Guthrie.

J T Rogers's Blood and Gifts was initially presented in shortened form as part of the Tricycle Theatre's The Great Game season and has now been expanded into a full-length production for the National Theatre. Set between 1981 and 1991, the play shows how US and British efforts to combat the Soviet occupation of Afghanistan led them to promote, fund and arm Islamic resistance movements within the country. As such, it is a timely reminder of the extent to which the problems that Western imperialism is now facing are of its own creation.

These replicas are regularly joined by orange-suited volunteers. One of the organisers explained that "it was to remind people of Obama's unfulfilled promise to close Guantanamo".

Moira Buffini's Welcome to Thebes draws its inspiration from two very different sources. She combines ancient Greek mythology with modern politics. Athens becomes a global superpower, with Thebes a wartorn country reminiscent of Liberia. The result is hugely effective. Buffini is not content simply to retell old stories with modern clothes and a few swear words. She uses a mythical setting to tackle issues of race, gender and international relations. In doing so, she has created a compelling piece of political theatre.

Canary charts the experiences of being a gay man in Britain from the 1960s onwards. It takes as its title a quote from gay activist Peter Tatchell who said, "We are the canaries in the mine," the "litmus test of whether a society is democratic and respecting human rights".

It is a tremendously strong play, successfully weaving a history of struggle into the personal stories of four gay men whose lives illustrate the huge changes over the last 40 years.

Bola Agbaje's second play for the Royal Court explores the choices that face David, Kojo and Sharon, childhood friends hardening up to the realities of being 20-somethings trapped in the harsh landscape of inner-city London. This fast-paced and hard-hitting play attempts to shock its audience into the realities of what is often crudely termed "Black Britain" today. Class dynamics soon explode upon the stage.

Certainly, the past year has been punctuated by some remarkable plays and the impressive bursts of new theatre writing in 2009 look set to continue this year. Many upcoming plays will directly engage with how the recession is affecting ordinary people.

A little over a year since the collapse of Lehman Brothers investment bank and the resulting economic meltdown, the theatre industry finally seems to be catching up. David Hare's new play is the latest in a spate of new work to take the financial crisis as its subject matter.

Subtitled "A Dramatist Seeks to Understand the Economic Crisis", The Power of Yes is essentially an edited compilation of interviews conducted by the author over the past year with a multitude of people who were at the heart of the crash, and who give their own accounts of what happened.
