Ramsar - IRNA - The significant increase in land prices in the west of Mazandaran in recent years has made selling agricultural lands and changing their use a tempting option for some owners. A trend that experts consider a threat to the future of production and sustainable development of the region. On the other hand, the development of the cultivation of economic crops compatible with climatic conditions, such as blueberries, especially in the form of tourism farms, from the point of view of the officials and activists of this field, can be an opportunity and a solution for the economicization of agriculture and increasing the income of farmers and preserving their lands.
