“…There were many solutions to adapt to salinity intrusion proposed or implemented for the VMD. The appropriate solutions for Tra Vinh included (i) sluice gate systems for salinity prevention (currently in operation) [90,91], (ii) changing crop structure to adapt to drought and salinity (for example, salinity-/drought-resistant varieties) [7,76,92,93], (iii) reducing the number of crops per year (from three crops/year to two or one crop yearly) [7,94,95], desalination for domestic water use [96], (iv) monitoring, forecasting and early warning of salinity intrusion [97,98], (v) climate-smart agriculture (rice-shrimp) [92,99,100], and (vi) improving agro-fishery value chains [101][102][103][104]. However, despite the vast array of strategies, there still remain implementation challenges, such as farmers' low awareness, lack of investment in production equipment [105], and the complicated socio-hydrological factors in the region.…”
