Они стабилизируют почву и климат, регулируют водосток, дают тень и укрытие, создают ареал обитания для опылителей и естественных врагов сельскохозяйственных вредителей. Они также вносят свой вклад в обеспечение продовольственной безопасности сотен миллионов людей и служат для них важным источником питания, энергии и дохода.
