  • 5.1 Barley yields on regosols (kg/ha) with different soil depth and slope without fertilizer or
  • manure application
  • 5.2 Barley yield declines over 5 years on andosols and regosols, without and with fertilizer (55
  • kg of N/ha and 50 kg of P2O5), with and without conservation technology
  • 5.3 The impact of improved access to credit, off-farm employment, and both credit and off-farm

  • 5.4 The impact of introducing food-for-work (FFW) when FFW is not used for conservation,
  • access to the labor market is constrained, and land conservation does not reduce initial yields
  • 5.5 The impact of food-for-work (FFW) when FFW is used for land conservation, access to the

  • 5.6 The impact of tree planting and food-for-work (FFW) for land conservation
  • 5.7 The impact of planting eucalyptus.
