Green Economy and Food Security
renewable energy is the key to green economy
solar
Harnesses the power of the sun through photovoltaic (PV) cells or concentrated solar power (CSP)
Can be distributed or Utility Scale Solar Energy (USSE)
wind
Harnesses the power of the wind through turbines
Can be onshore or offshore
bioenergy
Harnesses the power of plants and animals through thermochemical or biochemical conversion
Can be traditional (wood, charcoal, and dung) or modern (bio-heat, biofuels, bioethanol)
hydropower
Harnesses the power of water through turbines
Can be conventional from dams, run-of-river hydropower, or pumped-storage hydropower
geothermal energy
Harnesses the power of the earth’s crust
Can be single-home or power plant-sized
ocean energy
Harnesses the power of the ocean’s tides and currents through turbines
Obtains energy from tides, currents, wind waves, or take advantage of thermoclines, or osmotic energy
food security
Food and nutrition security is when all people at all times have physical, social, and economic access to food.
Malnutrition takes two forms: undernutrition & overnutrition
Mobilization of neglected and underutilized food crops and wild food may improve global food security
Over-reliance on certain crops and animals
Reduction of inputs
Food quality
Cultural and dietary diversity
Equilibria
Bush meat and wild fish harvesting generally are ungoverned and unsustainable
Land conversion is the dominant development paradigm, but not necessarily the solution
leads to
loss of cultures
Conflict over land
overexploitation
