Revealing the spatial differentiation of ecosystem service (ES) trade-offs and their responses to land-use change along precipitation gradients are important issues in the Loess Plateau of China. We selected three watersheds called Dianshi (300 mm < MAP (mean annual precipitation) < 400 mm), Ansai (400 mm < MAP < 500 mm), and Linzhen (500 mm < MAP < 600 mm). A new ES trade-off quantification index was proposed, and quantile regression, piecewise linear regression, and redundancy analysis were used. The results were as follows. (1) Carbon sequestration (TC) and soil conservation (SEC) increased, but water yield (WY) decreased in the three watersheds from 2000 to 2018. (2) The effect of forests on trade-offs was positive in three watersheds, the main effect of shrubs was also positive, but the negative effect appeared in the TC-WY trade-off in Ansai. Grassland exacerbated trade-offs in Dianshi, whereas it reduced trade-offs in Ansai and Linzhen. These effects exhibited respective trends with the quantile in the three watersheds. (3) There were threshold values that trade-offs responded to land-use changes, and we could design land-use conversion types to balance ESs. In general, the water consumption of grass cannot be ignored in Dianshi; shrubs and grass are suitable vegetation types, and forests need to be restricted in Ansai; more forests and shrubs can be supported in Linzen due to higher precipitation, but the current proportions of forests and shrubs are too high. Our research contributes to a better understanding of the response mechanisms of ES trade-offs to land-use changes.

Ecosystem services (ES), defined as benefits provided by the ecosystem to society, are essential to human well-being. However, it remains unclear how they will be affected by land-use changes due to lack of knowledge and data gaps. Therefore, understanding the response mechanism of ecosystem services to land-use change is critical for developing systematic and sound land planning. In this study, we aimed to explore the impacts of land-use change on the three ecosystem services, carbon storage (CS), flood regulation (FR), and soil conservation (SC), in the ecological conservation area of Beijing, China. We first projected land-use changes from 2015 to 2030, under three scenarios, i.e., Business as Usual (BAU), Ecological Land Protection (ELP), and Rapid Economic Development (RED), by interactively integrating the Markov model (Quantitative simulation) with the GeoSOS-FLUS model (Spatial arrangement), and then quantified the three ecosystem services by using a spatially explicit InVEST model. The results showed that built-up land would have the most remarkable growth during 2015–2030 under the RED scenario (2.52% increase) at the expense of cultivated and water body, while forest land is predicted to increase by 152.38 km2 (1.36% increase) under the ELP scenario. The ELP scenario would have the highest amount of carbon storage, flood regulation, and soil conservation, due to the strict protection policy on ecological land. The RED scenario, in which a certain amount of cultivated land, water body, and forest land is converted to built-up land, promotes soil conservation but triggers greater loss of carbon storage and flood regulation capacity. The conversion between land-use types will affect trade-offs and synergies among ecosystem services, in which carbon storage would show significant positive correlation with soil conservation through the period of 2015 to 2030, under all scenarios. Together, our results provide a quantitative scientific report that policymakers and land managers can use to identify and prioritize the best practices to sustain ecosystem services, by balancing the trade-offs among services.

Runoff And Sediment Yield

Land-use change has a significant influence on runoff process of any watershed, and the deepening of this theme is essential to assist decision making, within the scope of water resources management. The study was conducted for Mundaú River Basin (MRB) using the Soil and Water Assessment Tool (SWAT) model. The study aims to assess the issue of land-use change and its effect on evapotranspiration, surface runoff, and sediment yield. Input data like land use, topography, weather, and soil data features are required to undertake watershed simulation. Two scenarios of land use were analyzed over 30 years, which were: a regeneration scenario (referring to use in the year 1987) and another scene of degradation (relating to use in the year 2017). Land use maps for 1987 and 2017 were acquired from satellite images. Overall, during the last three decades, 76.4% of forest was lost in the MRB. The grazing land increased in 2017 at a few more than double the area that existed in 1987. Changes in land use, over the years, resulted in an increase of about 37% in the water yield of MRB. Changes have led to increased processes such as surface runoff and sediment yield and in the decrease of evapotranspiration. The spatial and temporal distribution of land use controls the water balance and sediment production in the MRB.

&lt;p&gt;Hydrological processes at basin scale are driven by climate and land-use changes. Hiso River watershed (HRW) is within a radiocesium contaminated area caused by the disaster in Fukushima Daiichi nuclear power plant (FDNPP). It&amp;#8217;s urgently needed to make evaluations on how changes of climate and land-use bring impacts on hydrological processes, which control pollutants transport in watershed. This study applied a combination method of Statistical DownScaling Model (SDSM) and Soil and Water Assessment Tool (SWAT) to generate future climatic and hydrologic variables. Future climate data was obtained from three Representative Concentration Pathway (RCP2.6, 4.5 and 8.5) scenarios of a single General Circulation Models (GCMs) in three future periods of 2030s, 2060s and 2090s (2010-2039, 2040-2069, 2070-2099), with a baseline period (1980-2009). Furthermore, according to land-use change in HRW during 2013-2017, three land-use change scenarios under the three future climate scenarios were established. Results suggested that SDSM showed good capabilities in capturing daily maximum/minimum temperature and precipitation. The SWAT model presented good performances in simulating monthly and yearly streamflow. Results also suggested projected higher temperatures and lower rainfall led to decreased annual water yield and evapotranspiration (ET). The annual water yield and ET decreased in most seasons while had a slight increase in spring. RCP8.5 scenario always generated larger magnitudes for climatic variables and water balance components compared with other climate scenarios. Land-use changes had strong impact on surface runoff and groundwater flow. These findings could provide reference for decontamination and revitalization policy-making under complicated land use and climate change conditions.&lt;/p&gt;

Identifying the relationships between ecosystem services (ESs) and land use change is crucial for ES management and sustainable regional development. The Manas region in China has witnessed dramatic reclamation activities in its desert areas that resulted in ecological problems. The changes in eight ESs, including crop production (CP), livestock production (LP), soil conservation (SC), water yield (WY), sand fixation (SF), carbon sequestration (CS), habitat quality (HQ), and nature landscape recreation (NLR), were investigated by using biophysical and questionnaire methods. At the regional scale, provisioning services (i.e., CP and LP) showed some performance improvements, whereas most of the regulating services (i.e., WY, CS, and HQ) along with NLR showed a performance decline. Five ES bundles—Upper Mountain, Foothill, Oasis, Oasis–Desert Transition, and Desert bundle—were identified at the township scale via k-means clustering. From 2000 to 2015, the Oasis bundle sprawled as a result of oasisization, whereas the Oasis–Desert Transition and Foothill bundles decreased. We performed a questionnaire survey and a statistical analysis to identify the causes behind the performance improvement/decline of these ESs and found that the land use changes in the Manas region had a significant impact on these services. More than 50% of the survey respondents identified land use changes as the primary driver of the changes in some ESs (i.e., CP, CS, HQ, and NLR). In the correlation and partial correlation analyses, oasisization was significantly and positively correlated with CP but was negatively correlated with WY, CS, HQ, and NLR. We enhanced the reliability of our conclusions by integrating biophysical and sociocultural methods into our investigation of ES and land use change. In view of the huge losses in regulating and cultural services, the Manas region should limit its desert reclamation activities to control the expansion of its oasis and to improve the quality of its cropland. Our results can help formulate effective ES management and land use decisions in the Manas region or similar areas.

Abstract. Land use changes are altering the hydrologic system and have potentially large impacts on water resources. Rapid socio-economic development drives land use change. This is particularly true in the case of the rapidly developing city of Pune, India. The present study aims at analyzing past land use changes between 1989 and 2009 and their impacts on the water balance in the Mula and Mutha Rivers catchment upstream of Pune. Land use changes were identified from three Rivers catchment multitemporal land use classifications for the cropping years 1989/1990, 2000/2001, and 2009/2010. The hydrologic model SWAT (Soil and Water Assessment Tool) was used to assess impacts on runoff and evapotranspiration. Two model runs were performed and compared using the land use classifications of 1989/1990 and 2009/2010. The main land use changes were identified as an increase of urban area from 5.1% to 10.1% and cropland from 9.7% to 13.5% of the catchment area during the 20 yr period. Urbanization was mainly observed in the eastern part and conversion to cropland in the mid-northern part of the catchment. At the catchment scale we found that the impacts of these land use changes on the water balance cancel each other out. However, at the sub-basin scale urbanization led to an increase of the water yield by up to 7.6%, and a similar decrease of evapotranspiration, whereas the increase of cropland resulted in an increase of evapotranspiration by up to 5.9%.

The Impact

&lt;p&gt;As a result of climate change, improving the efficiency of our water management has become a key social goal in recent decades. In many regions, water management problems are becoming more common as the result of hydrologic extremes, such as water scarcity, drought or floods.&lt;/p&gt;&lt;p&gt;Countries and regions dealing with water problems, like some parts of Hungary, could avoid major damage by land use change. The possibility of land use change is obviously not an option in certain instances, especially in populated areas or areas with major infrastructure (roads, railways, airports, factories, etc.). At the same time, non-populated areas (primarily agricultural land) may be transformed in the future, in the hope of better water management.&lt;/p&gt;&lt;p&gt;Complex, multi-dimensional assessment of ecosystem services can be a step forward in the evaluation and planning of future land use changes with the aim of improving water resources management. The strength of this approach is multi-disciplinarity, which requires the collaboration of representatives of the technical, economic, social and ecological sciences.&lt;/p&gt;&lt;p&gt;In our study, we quantified and mapped the most important water resources related indicators and services of the Zala River basin in Western Hungary. Zala River is the largest sub-catchment of Lake Balaton, Central-Europe&amp;#8217;s largest standing water. The lake has great economic and social importance in Hungary, primarily due to its recreational and cultural services, so it is necessary to have sufficient quantity and quality of water. &amp;#160;The catchment area is 1521 km&lt;sup&gt;2&lt;/sup&gt;, land use conditions are dominated by agricultural and forest areas (around 57% and 37% respectively).&lt;/p&gt;&lt;p&gt;For the quantification of ecosystem services indicators, we used the GIS based, static model package InVEST (Integrated Valuation of Ecosystem Services and Tradeoffs). InVEST is suggested to describe the socio-ecological state of several services, under various periods or land use conditions. The strength of the model lies in its solid data requirements and low computational demand. In our work, we mapped the following services and indicators: annual water yield, seasonal water yield, quickflow, nutrient retention, sediment retention and agricultural crop yields.&lt;/p&gt;&lt;p&gt;We examined the impact of different interventions on the ecosystem services. We intervened primarily in areas where agricultural land use is not justified due to different environmental conditions. In these areas, we analyzed the introduction of natural surfaces with afforestation and meadows. We built up a reference (based on a novel LULC map representing actual conditions) and some fictive model variants. These model variants differed in the amount and location of the new semi-natural areas. The variants were compared for two temporal periods: 1980-2010 and 2020-2050 (based on climate models).&lt;/p&gt;&lt;p&gt;We quantified the tradeoffs as a result of a given land use change. As expected, the future negative effects of climate change could be mitigated by increasing semi-natural areas. All ecosystem services would improve except for crop yields. At the same time, however, farmers would be deprived of significant yields in areas, which are excluded from agriculture. Our research highlights that the positive effects or tradeoffs due to land-use change will be needed in the future.&lt;/p&gt;

Environmental managers and policymakers increasingly discuss trade-offs between ecosystem services (ESs). However, few studies have used nonlinear models to provide scenario-specific land-use planning. This study determined the effects of different future land use/land cover (LULC) scenarios on ESs in the Yili River Valley, China, and analyzed the trade-offs and synergistic response characteristics. We simulated land-use changes in the Yili River Valley during 2020–2030 under three different scenarios using a patch-generating land-use simulation (PLUS) model—business as usual (BAU), economic development (ED), and ecological conservation (EC). Subsequently, we evaluated the water yield (WY), carbon storage (CS), soil retention (SR), and nutrient export (NE) ESs by combining the PLUS and integrated valuation of ecosystem services and trade-offs (InVEST) models, thus exploring multiple trade-offs among these four ESs at a regional scale. For the BAU scenario, there are some synergistic effects between WY and SR in the Yili River Valley, in addition to significant trade-off effects between CS and NE. For the ED scenario, the rapid expansion of cropland and constructed land is at the expense of forested grassland, leading to a significant decline in ESs. For the EC scenario, the model predicted that the cumulative regional net future carbon storage, cumulative water retention, and cumulative soil conservation would all increase due to ecological engineering and the revegetation of riparian zones and that formerly steep agricultural land can be effective in improving ESs. Meanwhile, the trade-off effect would be significantly weakened between CS and NE. These results can inform decision makers on specific sites where ecological engineering is implemented. Our findings can enhance stakeholders’ understanding of the interactions between ESs indicators in different scenarios.

AbstractNowadays, tropical forest landscapes are commonly characterized by a multitude of interacting institutions and actors with competing land-use interests. In these settings, indigenous and tribal communities are often marginalized in landscape-level decision making. Inclusive landscape governance inherently integrates diverse knowledge systems, including those of indigenous and tribal communities. Increasingly, geo-information tools are recognized as appropriate tools to integrate diverse interests and legitimize the voices, values, and knowledge of indigenous and tribal communities in landscape governance. In this paper, we present the contribution of the integrated application of three participatory geo-information tools to inclusive landscape governance in the Upper Suriname River Basin in Suriname: (i) Participatory 3-Dimensional Modelling, (ii) the Trade-off! game, and (iii) participatory scenario planning. The participatory 3-dimensional modelling enabled easy participation of community members, documentation of traditional, tacit knowledge and social learning. The Trade-off! game stimulated capacity building and understanding of land-use trade-offs. The participatory scenario planning exercise helped landscape actors to reflect on their own and others’ desired futures while building consensus. Our results emphasize the importance of systematically considering tool attributes and key factors, such as facilitation, for participatory geo-information tools to be optimally used and fit with local contexts. The results also show how combining the tools helped to build momentum and led to diverse yet complementary insights, thereby demonstrating the benefits of integrating multiple tools to address inclusive landscape governance issues.
