The 2019 Annual Report outlines the CGIAR Research Program on Fish Agri-Food Systems (FISH) achievements in delivering evidence-based solutions that address the complex challenges and opportunities in fish agri-food systems in the developing world. Three years into the Program, FISH research is having a positive impact on the lives of people who depend on fisheries and aquaculture in global food systems.
Mangroves are now well known to provide a range of ecosystem services that benefit local populations, though such ecosystem services are at risk from mangrove deforestation and degradation across much of the tropics. This study aimed to identify the natural and anthropogenic drivers of change that affect ecosystem services of the Sundarbans mangrove forest.
After commencing with a summary of the current status, importance and productivity of natural wetlands, the chapter reviews the contribution of wetland ecological functions to sustaining vital ecosystem services. Wetlands are vulnerable to a range of anthropogenic pressures, notably land use change, disruption to regional hydrological regimes as a result of abstraction and impoundment, pollution and excessive nutrient loading, the introduction of invasive species and overexploitation of biomass, plants and animals.
Commencing with a summary of the current status, importance and productivity of natural wetlands the contribution of wetland ecological functions to sustaining vital ecosystem services is then reviewed. Provisioning services, notably fish and water for irrigation or domestic and industrial purposes constitute important benefits derived by humanity from wetlands, whilst recognition is growing that supporting, regulating and cultural services supported by wetlands are critical for sustaining social-economic systems and ensuring human well-being.
Coral reefs are recognized as globally important ecosystems, for their fisheries, tourism and biodiversity values in particular, with an estimated annual contribution of $30 billion to the global economy. The benefits that coral reef ecosystems provide through their provisioning, regulating, cultural and supporting services are critical for human wellbeing. The Coral Triangle region (which includes the waters of Indonesia, Malaysia, Papua New Guinea (PNG), the Philippines, Solomon Islands and Timor Leste) supports the highest coral and reef fish species diversity in the world.
The AusAID Development Research Project: Poverty Alleviation, Mangrove Conservation and Climate Change: Carbon offsets as payment for mangrove ecosystem services in Solomon Islands (# 49892) was designed to evaluate the potential for mangrove carbon revenue programs in Solomon Islands. The approach was to address three main questions: (1) How are mangrove ecosystem goods and services currently used and valued by coastal populations with a high reliance on a subsistence economy? (2) What is the total carbon stock held in mangrove ecosystems?
This brochure is part of a series that collectively detail how a community-based assessment of climate change was used in partnership with coastal communities and provincial and national-level stakeholders in Timor-Leste and Solomon Islands. The assessment contains four distinct, but related, steps focused on supporting community-level decision-making for adaptation through a series of participatory action research activities. Each brochure in this series details a specific activity in the four-step assessment.
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.
Nations of the Greater Mekong Subregion need to ‘rethink’ their agricultural industries to meet future food needs, given the social shifts and climate changes that are forecast for the coming decades. With better farming practices, and by managing agriculture within the wider context of natural ecosystems, nations could boost production and increase the wealth and resilience of poor people in rural communities. Demand for food is forecast to double by 2050, as populations swell and people’s dietary choices change.
Lakes Malawi, Malombe and Chilwa produce almost all the fish consumed in Malawi. The ecologies of these lakes are very different. These differences present significant challenges in implementing policies and management strategies that can sustain the livelihoods of people dependent on these lakes. Increasing fisheries exploitation, land transformation, irrigation and climate all threaten the flow of benefits from these remarkable water bodies.
