Inland fisheries

  • Increased

purchasing power,

  • Social safety net,
  • Cash for income,
  • Inland finfish

value USD 43 billion in 2015.

  • Improved

human health/ wellbeing,

  • Community

identity,

  • Recreation.

Food/ Nutritional Security

  • Women involved

in decision making,

  • Full- time and

part- time employment.

Importance of Inland Fisheries

Economic

  • Increased

micronutrient intake,

  • Access to animal

protein,

  • Catch retained for

household consumption. Employment/ Empowerment Cultural

FAO 2015 Global and regional capture fisheries production (11.47 million tonnes) Water footprint, land use and energy content of alternative foods Additional water demand (km3), land conversion (km2), and food production to replace kilojoules from fish (million tonnes)

Method

SLIDE 6

Kilojoule replacement

  • Aquaculture- 6 times global production,
  • Livestock- 8% of global production,
  • Crops- 2% of global production.

African Great Lakes (1.1 million tonnes)

Water demand

  • Beef- 1.2 times regional

water use Land use

  • Aquaculture- 51% regional

inland water area

  • Beef- 14% of regional pasture

Reduction in nutrients

Impact

  • f Inland

Fish loss

Increased food imports Dietary change Agricultural expansion Livelihood transition No access to capital No access to land Micronutrient deficiencies

Impact of Inland Fish loss

Increased food imports Dietary change Agricultural expansion Livelihood transition Increased food prices Food insecurity Water quality decline Land- use change

Water as a resource

Water as Resource Water for Livelihoods

Employment Profit Food security (i.e. fisheries) Hydropower Agriculture/ Industry Natural resources use

The delicate balance

slide-15
SLIDE 15

Recognition of inland fisheries as a major food production sector Cross- sector cooperation between competing water use sectors Inclusion of inland fisheries in water policy and food security discussions

Recommendations
