Decision support for water management for integrating aquaculture in small-scale irrigation systems

A three-year project was funded by the BMZ/GIZ to examine the benefits of integrating aquaculture and small scale irrigation by identifying improved water allocation and management strategies under current and future climate change scenarios. An integrated modeling approach was adopted to analyze the complex issues involved in the decision processes.

Climate, Change, Water Management and Aquaculture in Malawi

The increasing variability of climate is a challenge for small-scale farmers in Chingale, Malawi. Changing weather patterns mean that farmers are unable to fully prepare their cropping calendars for optimal harvests, and irregular rainfall is causing unpredictable crop yields. With small land sizes of less than 0.2 hectares, small-scale farmers need to make full use of their available land in order to have enough food for their families and surplus for sale. To adapt to these challenges, farmers are integrating fish farming and crop irrigation to their farming practices, which are providing extra food and income.

A Glimpse From the Field: A Ganges Study Tour

Optimizing Water Management for Local Livelihoods in the Mekong Basin

With the high potential of hydroelectricity development, the Mekong Basin region faces a rapid, widespread development pressure in the decades to come. Cambodia, Lao PDR, and Vietnam are the main focus areas where more hydropower dam projects are to be built along the Mekong tributaries. Though such projects significantly contribute to regional and national economic growth, local riparian communities are the ones who bear the brunt of the environmental impacts they cause.  Livelihoods of local communities heavily depend on water from rivers and other natural resources in the area a complex way but this complexity is often overlooked by the environmental and social impact assessments conducted for hydropower projects. The past projects in the region, and from around the world, give us a glimpse of the magnitude of short-term and long-term impacts on the livelihoods of riparian communities.
