Scaling up community-based adaptation

Charting a course among the long, narrow fishing boats that plied back and forth across the river, the ferryboat pulled in to Chila market. Election posters fluttered in the breeze. A young man pedaled past on a rickshaw, his distorted voice blaring out campaign slogans from a large megaphone. Flashes of electric blue caught the eye where women, men, boys and girls drag-netted the river banks in search of shrimp. A day and a half’s drive, river-ferry crossing and boat-ride to the south-west of the capital, Dhaka, Chila is one of the last villages on Bangladesh’s mainland before you reach the Sundarbans – the world’s largest area of mangrove forest and an essential protective barrier against floods and storm surges which climate change is only expected to exacerbate. We had come to see for ourselves how local communities are adapting to some of the changes that climate change is expected to bring.

This week in Dhaka, over 350 people from 60 countries met to exchange knowledge on ways to meet the challenge of scaling up community-based approaches to climate change adaptation. This was the fifth such international conference, organized by the Bangladesh Center for Advanced Studies (BCAS) and the International Institute for Environment and Development (IIED), and supported by 37 other international NGOs and bilateral and multilateral development agencies including the World Bank. In her inaugural address, the Prime Minister of Bangladesh, Sheikh Hasina, called upon participants to come together in a spirit of mutual learning, not just from each other, but also from the communities that a number of us visited during three days of field visits.

The trip I joined to Chila took place on an historic day. Over the holiday weekend marking this young country’s 40th anniversary since independence, local elections were also taking place for the first time in 12 years. On the way to the ferry, our bus driver took us on an unannounced detour so he could go and vote. Once in Chila, we talked with community members at the local market and in their homes, often precariously balanced between shrimp ponds, stretching as far as the eye can see, where not so long ago there were only rice paddies.

They told us that the two-storey school building nearby doubled as a cyclone shelter and saved many lives during Cyclone Aila two years ago. Lessons had been learnt from Cyclone Sidr in 2007 when many were less fortunate. They now pay greater attention to the cyclone early warning or ‘signaling’ system, when they hear messages – through the same megaphones that we heard used for electioneering – urging them to take shelter from winds and impending storm surges. With the assistance of BCAS and a local NGO called Rupantar (meaning ‘social transformation’), poor households had received assistance with raising their homes on plinths a meter and a half above the level reached by Cyclone Aila’s floodwaters; and with developing simple systems for harvesting rainwater from rooftops to provide drinking water in this increasingly saline environment.

What we saw of local NGO efforts was clearly of great value to poor households struggling to meet daily needs such as drinking water and flood protection. Their livelihoods are not well adapted even to existing climate extremes, let alone to future climate changes. But some of the immediate and pressing livelihood concerns they face have less to do with climate change than with other, underlying causes of vulnerability. Rising salinity, for example, may have more to do with the impounding and extraction of fresh water up-river, thereby allowing salt-water to intrude further inland; and to the conversion of rice paddies to shrimp ponds, which has arguably led to a narrowing of livelihood (or adaptation) options open to people in Chila, both today and in the future. It seemed likely that a threshold would eventually be reached when in situ adaptation measures within Chila would no longer be sufficient, and when options further afield – such as temporary wage labor migration or even more permanent forms of voluntary migration – might increasingly be needed.

During this week’s conference deliberations, participants reflected on these challenges and what they might mean for scaling up CBA. I chaired a session on bridging local, sub-national and national levels of engagement. The presenters stressed the importance of building on strong local institutions to ensure that adaptation measures benefit those whose livelihoods are most sensitive to climate change and who most lack the capacity to adapt. At the same time, they suggested, it is important to connect upwards to the policy, legislative, planning and budgeting frameworks needed to sustain such outcomes at scale and over time. In his closing address to the conference, the Chair of the Intergovernmental Panel on Climate Change (IPCC), Dr. Rajendra Pachauri, also highlighted the need for practitioners and analysts of CBA to engage with forward planning for adaptation under conditions of uncertainty . In a session on tools for CBA, there was some discussion of participatory scenario development, for example, as one possible way of grappling with this challenge.

Scaling up CBA isn’t a question of simply stitching together a ‘patchwork quilt’ of local initiatives, as IIED’s Saleemul Huq, one of the conference organizers, aptly put it. This could be a recipe for maladaptation in many places. But the real contribution of the CBA movement in recent years has been to show that top-down approaches to adaptation will also founder if they fail to connect with the felt priorities of those most vulnerable to climate change.
