THE SUSTAINED AGRICULTURAL DEVELOPMENT OF

TROPICAL WETLANDS IN SOUTH AMERICA AND AFRICA

Objectives

The main objectives are as follows :

F
To develop a programme for the sustained exploitation of two major freshwater wetland systems in the tropics. These are the floating grass swamps dominated by Echinochloa polystachya in Amazonia and the Cyperus papyrus swamps of east and central Africa.

F
To quantify the role of the wetland systems as carbon sinks by determining the amounts of carbon in the different components of the systems and the cycling of carbon between the atmosphere, the water and these components.

F
To produce a mechanistic simulation model of the carbon balance of the wetland systems, and to use this to predict how management practice will alter the carbon balance of the community in the future.

Activities

The key activities envisaged are :

*
to organise a workshop in Essex to establish the methodology for carbon balance measurements;

*
to determine the carbon balance of the E. polystachya ecosystem in the Amazon basin and investigate how its removal alters the carbon balance of the region;

*
to determine the carbon balance of papyrus-dominated swamps in Africa and the effect of harvesting the aerial vegetation on the carbon balance;

*
to organise a workshop in Dublin to review with The Biocomposite Centre, Bangor the utilisation of emergent vegetation;

*
to determine the extent to which E. polystachya may be utilised as an animal feed and provide a sustainable source of fodder;

*
to determine how the papyrus vegetation can be utilised when harvested regularly.

Expected outcome

The work outlined in this proposal is expected to show how tropical wetlands can be exploited in a sustainable way. It will also help to quantify the contribution that these wetlands make to global carbon cycling and whether they are a significant carbon sink.
