Governance of aquatic agricultural systems: Analyzing representation, power, and accountability

Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders over rights to access and use natural resources, land, water, wetlands, and fisheries, essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision making amidst competition that spans sectors and scales, building capacities for resilience, and for transformations in institutions that perpetuate poverty.

Decision support for water management for integrating aquaculture in small-scale irrigation systems: A case for the Chingale catchment in Malawi

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. A water budgeting approach was used in estimating and balancing the water resources available to farming communities (the supply aspect) and the water demand for agricultural use, including crops and fish farming, within a catchment.

Seasonality dynamics for investigating wetland-agriculture nexus and its ecosystems service values in Chibuto, Mozambique

This study is a subsection of CPWF-30 (Challenge Program on Water and Food) that centers on investigating the wetland, agriculture, and livelihoods interactions. Chibuto, the floodplain of Changane River in Mozambique is a representative downstream site for the Limpopo sub-catchment. It largely serves as an agro-ecosystem with agricultural, grazing, and fiber collection as the prominent set of ecosystem services. The present analysis is a three-tier framework conceptualized to develop a synoptic overview of spatial, social, and economic elements that governs the system dynamics.

Seasonal dynamics of physico-chemical characteristics and biological responses of Lake Chilwa, Southern Africa

Lake Chilwa is shared by Malawi and Mozambique, it supports an important fishery and its watershed is undergoing rapid population growth and increasing utilization for agricultural production. It is a shallow, closed basin lake with extensive surrounding wetlands; and it has suffered several desiccation events in the last century. To better understand the current condition of the lake, we monitored a suite of physical, chemical and biological parameters at approximately monthly intervals over an annual cycle in 2004–2005.

Fisheries and aquaculture research capabilities and needs in Africa: studies of Kenya, Malawi, Mozambique, Zimbabwe, Mauritania, Morocco, and Senegal

This Technical Report contains the results of 2 missions. One mission deals with the state of fisheries andaquaculture research as well as research needs in 4 countries in Southeastern Africa: Kenya, Malawi,Mozambique and Zimbabwe. Following an analysis of relevant criteria for evaluating fisheries and aquaculture research, an account is given of the factors affecting the effectiveness of research in the 4 countries covered by the mission and also more generally in subsaharan Africa.

Vulnerability of coastal livelihoods to shrimp farming: Insights from Mozambique

Millions of people around the world depend on shrimp aquaculture for their livelihoods. Yet, the phenomenal growth of shrimp farming has often given rise to considerable environmental and social damage. This article examines the impacts of commercial, export-oriented shrimp aquaculture on local livelihood vulnerability by comparing the exposure, sensitivity, and adaptive capacity of shrimp farm employees with non-farm employees in rural Mozambique.

Strengthening governance across scales in aquatic agricultural systems

Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders operating from local to national and regional scales over rights to access and use natural resources—land, water, wetlands, and fisheries—essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision-making amidst such competition, building capacities for resilience and transformations that reduce poverty.

The socio-economic context for improving food security through land based aquaculture in Solomon Islands: A peri-urban case study

Future fish demand-supply scenarios project that investment in aquaculture will be needed to ensure fish for food security in Solomon Islands. In 2010 a study of two peri-urban areas of Solomon Islands analysed the demand and potential for inland aquaculture, and the role of the introduced Mozambique tilapia (Oreochromis mossambicus) in household livelihoods and existing value chains. Of 178 households interviewed, marine reef fish were the preferred fish for consumption, although tinned fish was also common.
