The expanding global population poses challenges in waste management and food production, necessitating sustainable solutions like black soldier fly larvae (BSFL) for organic waste recycling and protein production. This PhD thesis evaluates the use of BSFL as poultry feed, focusing on the conversion of human food waste and livestock forage into high-nutrient biomass.

Humid tropical environments, particularly the SAVA region in northeastern Madagascar, face crucial challenges in water resource management, exacerbated by land-use changes and climate modifications.

Soil organic carbon (SOC) is a key component of ecosystems, influencing soil health, fertility, and the carbon cycle. Intensive agricultural practices have led to SOC losses, increasing atmospheric carbon levels. This study explores the spatio-temporal variability and sequestration potential of SOC in cropland under different managementpractices.
