 a 8410500\, Israel)\nDesalination brine is increasingly recognized as a po
 tential resource rather than a waste stream requiring disposal. This study
  presents a modelling strategy for sequentially reusing desalination conce
 ntrate for food production\, fish culture (food) and irrigation of salt-to
 lerant halophytes crops\, including Atriplex lentiformis and Salicornia bi
 gelovii. The proposed system follows a serial structure in which brine is 
 progressively utilized through duckweed cultivation\, fish production\, an
 d halophyte irrigation. The halophyte component is particularly relevant t
 o the Ramat Negev region\, where groundwater salinity is approximately 4.4
  dS/m\, demonstrating the feasibility of saline-water agriculture under lo
 cal conditions. S. bigelovii plant is emphasized because of its high produ
 ctivity\, nutritional value\, livestock acceptability\, and broad salinity
  tolerance. For a small reverse-osmosis plant processing 50 m³ d⁻¹ and
  generating 27 m³ d⁻¹ of concentrate with an electrical conductivity o
 f 20.3 mS/cm\, the model estimates that 0.36 ha of cultivated land would b
 e required to utilize the entire concentrate stream. The system could prod
 uce approximately 10.3 metric tons of forage annually\, potentially suppor
 ting 37 goats or sheep\, 11 camels\, or 5 cattle. Although the estimated c
 rop value is modest (approximately €467/(ha*yr)\, the principal benefit 
 is resource recovery: converting desalination brine into livestock feed wh
 ile reducing concentrate disposal. The approach is scalable according to b
 rine availability\, land resources\, and livestock demand.\n\nhttps://indi
