Managing the ecosystem services and water-food-energy nexus is an important part of environmental decision-making [8; 9]. In addition, the water-food-energy nexus is known as a key driver of promoting SDGs and environmental sustainability [10]. The nexus approach includes policy suggestions under the synergy and trade-offs between the water, food and energy production and consumption system, so it can contribute to sustainable management [11; 12]. Understanding the relationship between environmental sustainability and the water-food-energy system requires integrating environmental and socio-economic dimensions [13; 14]. Previous studies have specifically focused on the environmental dimension of the ecosystem. Ecosystems provide services by generating socio-economic benefits, and the concept of the ecosystem services is critical in understanding the relationship between environmental sustainability and the water-food-energy system [15; 16; 17]. Furthermore, ecosystems have been emphasized as a component of improving not only ecosystem services, but also ecosystem resilience and climate change adaptation [18; 19]. Ecosystems include all three nexus pillars of water, food and energy; therefore, previous studies have described the relationships between ecosystems and the nexus concept. For example, the importance of ecosystems in supporting water cycles and food production has been analyzed based on the relationship between water and food [20]. In addition, the relationship between ecosystem habitats and agricultural intensification were also assessed to characterize the consequences for people and national development [19]. Ecosystem and energy relationships, between bio-fuels and energy consumption systems, have also been evaluated using an integrated analysis [21]. Ecosystems are not only fundamental for water and food sustainability, but are an important resource because they serve as the primary source of energy. Thus, the water-food-ecosystem (WFE) nexus could conceptually replace the water-food-energy nexus to provide eco-centric perspectives on forest and land management issue. Although the WFE nexus is a new proposal, the overall characteristics of the nexus approach were not changed. The WFE nexus is comprehensively integrated similar to the water-food-energy nexus, so socio-economic dimension should also be closely connected to each variable of water, food and ecosystem [22; 23]. Furthermore, understanding the current environmental and socio-economic status of land cover and land use both at global and regional levels, including the Mid-Latitude region, should be identified to appropriately balance the WFE nexus and achieve environmental sustainability [8]. In addition, differences in land development circumstances between regions could be conceptually connected in a global agenda for appropriate land management and the success of SDGs and the WFE nexus. The Mid-Latitude region generally refers to the area between 30\({}^{\circ}\) and 60\({}^{\circ}\) latitudes in the Northern Hemisphere. This region could be broadened to the area between the xeric belts and the tropical region, which is also described by diversity in climatic, geographic, demographic and national characteristics. Past warming trends between 15\({}^{\circ}\) and 45\({}^{\circ}\) latitudes have resulted in different future projections for changing land cover in temperate, arid and semi-arid climates [24; 25]. In addition, climate extremes have caused direct and indirect problems, such as abnormalities in temperature, decreasing gross primary productivity (GPP) and land degradation [25; 26; 27]. More than 50% of the world's population lives in this zone, which increases the pressure on natural resources and limits the adaptation and carrying capacity of the Mid-Latitude region. This directly affects the achievement of environmental sustainability and human well-being [28].
