Biodiversity, food security, nutrition and income through home gardens


The Biodiversity and Community Health (BaCH) Initiative’s partner Bioversity International started a home garden initiative in Nepal in 2002. Based on support from the Swiss Agency for Development and Cooperation in collaboration with Local Initiatives for Biodiversity, Research and Development (LI-BIRD) and other partners, the initiative studied how home gardens can contribute to biodiversity, food security, nutrition and household income.

A recent impact study highlights following results:

  • Home gardeners see their yields nearly triple from 300kg per year to as much as 900kg per year.
  • Biodiversity increased in the home gardens of participating households, with 66 species under cultivation as compared to fewer than 40 species before the project.
  • Farmers now maintain higher plant diversity and cultivate a greater range of plant groups – vegetables, fruits, spices, medicinal herbs, fodder and ornamentals.
  • More households are selling their garden products and participating households doubled their overall consumption of produce.
