Environment and livelihoods in tropical coastal zones : managing agriculture-fishery-aquaculture conflicts

---

The coastal zone is a big place: some 40% of the world’s population lives within 100 km of
the sea and this zone is under increasing pressure. Sustainable development and management
of coastal zone resources are vitally important to human well-being, to national
economies and to the ecosystems on which we depend.

In simple spatial terms, the coastal zone is the interface between the land and the ocean. It
comprises inshore waters below low-tide level, intertidal areas and tracts of land above hightide
level. It is an area of transition where terrestrial and marine environments interact, characterized
by a complex web of interactions among people, resources and ecosystems. This is
a functional aspect of the definition rather than a simple spatial relationship, which is critical
to our understanding of how it should be managed.

The coastal zone environment that is of particular interest to us is represented by river
deltas, mangrove swamps, salt marshes and estuaries where the land–water interface is gradual,
extensive and seasonally varying. It has the following characteristics:
● The aquatic environment is subject to seasonally varying salinity.
● The terrestrial environment is vulnerable to both tidal and riverine flooding.
● The natural resource base supports aquaculture, agriculture and fisheries.
The off-shore limit may be arbitrarily defined according to legal and administrative considerations,
but the inland boundary requires more careful consideration because of the
hydrological linkage between the coastal zone and inland river basins. There are examples of
many coastal zones being affected by a reduced flow of fresh water and sediment as a result
of dams, barrages and water diversions (e.g. Indus, Nile, Volta) that occur very long distances
upstream.

The focus of the book is around the challenges people face in managing crops, aquaculture,
fisheries and related ecosystems in inland areas of coastal zones in the tropics. A priority
issue that emerges from the case studies presented here is the impact of change on poor people
whose livelihoods depend upon open-access resources. Any development decision that
aims at enhancing production from aquaculture and/or agriculture is likely to adversely
affect access to and the productivity of these resources. Conflicts arise between different
stakeholders and in this book we discuss the nature of these conflicts and identify what is
known and not known about how to manage them. The book will therefore help planners,
resource managers and donors to make better-informed investment decisions in connection
with development of the coastal zone.
