Abstract. Barchia MF, Sulistyo B, Hindarto KS, Suhartoyo H. 2020. Assessment of Air Bengkulu (Indonesia) watershed based on agroecosystem landscape quality and sustainable land use plan. Biodiversitas 21: 5422-5430. This study purposes to assess agro-ecosystem landscape based on land quality values and current land use and assess agro-ecosystem matrices with agricultural conservation practices in Air Bengkulu Watershed conducted from August to December 2019. Spatial analysis used some map and Landsat 8 OLI satellite imagery and ArcGIS version 10.1. The analysis depicted spatial distribution of soil and land quality, land uses, agricultural landscape matrices, and sustainable agro-ecosystems. The assessments revealed soil quality covered Air Bengkulu Watershed categorized moderate 33.1% to good 14.4% suitable for sustainable agroecosystems while in marginal quality 38.9% mostly lying on the upstream. This unique landscape formed a land quality prone to degradation because of intensive agriculture for oil palm covering 60% and coffee plantation about 17%. Actually, only about 61.1% of the Air Bengkulu Watershed is categorized as moderate to good quality matrix of sustainable agroecosystems. Improper agricultural cultivation with monoculture system without implemented conservation practices drove landscape filled with degradation landscapes. With sustainable agro-ecosystem scenarios implementing physical conservation terraces and restored with multi-purposes tree species such as candlenut, kapok tree, betel nut, durian, good quality of the landscape matrix of 82% Air Bengkulu Watershed.

O uso indiscriminado das terras, sem considerar suas potencialidades e os graus de sensibilidade tem sido uma das principais causas de degradação dos solos, erosão e perda de capacidade produtiva das paisagens. O objetivo deste trabalho é avaliar a capacidade de uso da terra, identificando os conflitos decorrentes de sua utilização na bacia hidrográfica do Córrego Piraputanga-MT. Para tanto, realizou-se a reclassificação das classes de solos resultando no mapa de Erodibilidade. A associação desta informação com o fator topográfico originou o mapa de suscetibilidade à erosão. O mapa de cobertura vegetal e uso da terra foi elaborado a partir das imagens do Landsat 8 de 2017. Foi efetuada a análise da capacidade de uso das terras e avaliação dos conflitos derivados. Verificou-se que as Áreas de Preservação Permanentes têm sido desmatadas, 23,18% de sua extensão em situação de conflito com a legislação ambiental. Na bacia não houve a classe de alto conflito, porém caso não haja adoção de práticas conservacionistas é possível ocorrer, pois há áreas que se encontram em médio conflito de utilização, onde é recomendado a restauração da vegetação nas Áreas de Preservação Permanentes.Palavras–chave: Sensoriamento Remoto, Erosão do Solo, Degradação Ambiental.AbstractThe indiscriminate use of land, without considering its potentialities and degrees of sensitivity has been one of the main causes of soil degradation, erosion and loss of productive capacity of the landscape. The objective of this work is to evaluate the capacity of land use in the Piraputanga river basin, Mato Grosso, identifying the conflicts arising from its use. For this purpose, soil classes were reclassified resulting in the Erodibility map. The association of this information with the topographic factor originated the map of susceptibility to erosion. Map of vegetation cover and land use was elaborated by the use of images of Landsat 8 from 2017. The analysis of the land use capacity and the evaluation of the derived conflicts was carried out. Permanent Preservation Areas have been deforested, 23.18% of their extension in situation of conflict with the environmental legislation. In the Piraputanga basin there was no high conflict class, but if no adoption of conservation practices is taken, it is possible to occur, since there are areas that are in a medium class conflict of use, where it is recommended the restoration of the vegetation in the Permanent Preservation Areas.Keywords: Remote Sensing, Soil Erosion, Environmental Degradation

Land Use Plan

An ongoing, trinational project is providing the first environmentally sustainable economic development plan for the Ussuri River watershed (URW) in Far East Russia and northeast China. The URW is host to a unique mix of northern taiga and southern subtropical biota, and contains many endemic, relict, and highly threatened species of plants and animals. In Russia, severe monetary inflation and a shift to a market economy have left some aspects of forest biodiversity in jeopardy, particularly policing for wildlife poachers, regulating CITES (international wildlife trafficking) violations, ensuring long-term sustained production of timber and non-timber forest products, protecting unique habitats, and adequately staffing scientific reserves and funding needed research. In China, broad scale conversion of remaining wetlands to agriculture and rice paddies, and of diverse native forests to intensively managed, monocultural plantations, is helping to sustain the economy but is sacrificing biodiversity. A proposed sustainable land use plan has (1) mapped resource use areas, including both proposed and existing transborder nature areas, (2) encouraged foreign investment in both countries, and (3) encouraged sustainable development of natural resource markets that will be compatible with long-term conservation of biodiversity. A hallmark of this plan is integrating the needs of the people with the capacity of the land through both environmental protection and wise resource use.

The Impact

A land-use plan is a core policy tool to curb excessive non-agriculturalization of agricultural land. The effect of plan implementation can affect sustainable land use and regional development. Empirical studies have shown that land development commonly and frequently fails to conform to land-use plans. However, neither qualitative nor quantitative studies are conducted to comprehensively explore the reasons for zoning–land use mismatch. To help bridge this gap, this study explored to what extent a plan has been implemented and what factors have affected zoning–land use mismatch. A new deviation discriminant framework of planning implementation was presented. Moreover, the logistics model was applied to discuss which factors substantially affect the zoning–land use mismatch. The plan implementation results were divided into the conformed, exceeded and unused areas. The general land-use plan failed in its spatial control over rural settlements and other built-up lands, with both more than 90% of the newly added construction land beyond zoning. In addition, the newly added construction land of rural settlements, other built-up lands, and transportation lands all exceeded the quota control. Furthermore, the physical factors of distance from the river, the elevation, the slope and the level, and the social-economic factors of the gross domestic product, the fiscal revenue, the fixed assets investments, and the rank of town have prominent effects on zoning–land use mismatch. Enhancing the flexibility of the land-use plan and strengthening the relationship between planning quotas and spatial zoning in the future are necessary to promote the effect of plan implementation.

Farmland Protection

Farmland protection is the most important land science research issue in developing countries, especially in China, due to serious land degradation. This paper aimed to reveal the causal chain among driving factors, farmers’ land protection perceptions, behavioral responses, and land quality change by applying a structural equation model (SEM), based on a cross-sectional dataset of 238 households surveyed, and matched plot soil sample results in the Sujiatun District, in Liaoning province, China. The results show that, compared to internal factors, external factors play more important roles in shaping farmers’ land protection awareness which subsequently transfer into land protection behaviors. Various land use behaviors lead to different impacts on land quality, in which the crop planting structure and land input density have dominant effects on changes in the soil nutrient content. The results imply that a stable and reasonable price mechanism for agricultural inputs and outputs is meaningful to land protection. Moderate land circulation would help reduce land fragmentation, develop agricultural modernization, improve production efficiency, and achieve economies of scale. In addition, knowledge, training and environmental policy information on farmland protection play key roles in land conservation activities. These main results have important implications for policymakers with regard to promoting land protection activities, alleviating land resource and environmental pressures, and thus achieving the goal of sustainable land use.

Conservation Measures

Groundwater resources worldwide are being depleted at alarming rates since 1960 to support agriculture, industry, and domestic water demand. Water harvesting and the implementation of reduced application or more efficient irrigation technologies were identified as two of the most efficient practices to mitigate the declining patterns on groundwater resources. However, prior to implementing these practices, understanding how groundwater interacts with surface water and responds to natural and anthropogenic stressors is crucial. Integrated modeling tools that are able to exchange fluxes in both domains are needed to assess how conservation practices will affect our water resources under different projected climate and land use scenarios. This study aimed to evaluate the most likely impacts of current land management practices under the most severe projections of future climate and quantify the potential mitigation effects of three conservation scenarios on the water resources of the Fort Cobb Reservoir Experimental Watershed (FCREW) in western Oklahoma. The semicoupled SWAT-MODFLOW (SWATmf) model was used to simulate the hydrologic responses of the FCREW to a 50% reduction in the irrigation depths and the transition of 50% and 75% of croplands to rangelands under 32 distinct climate projections. Results showed that future climate can drive a reduction in the streamflow (−18%) and an increase to the depth of the water table (99%–120%) in the western part of the FCREW by the end of the century. The Fort Cobb Reservoir was expected to reduce its release after the mid-2060s to maintain its current target level. All the scenarios, aimed at decreasing groundwater extractions or implementing conservation measures, signaled a full recovery response in the groundwater levels 7–10 years after the year the conservation practices were implemented. The 50% reduction in the irrigation depths was found to elicit faster hydrologic systemic responses than the two that implemented conservation measures, which contravene tradition and would imply cessation of agricultural activities. This study can enable stakeholders to formulate timely adaptation and mitigating strategies to adopt to land use changes.

Soil Loss Equation

An erosion model using the Revised Universal Soil Loss Equation (RUSLE) equation derived from the Advanced Spaceborne Thermal Emission and Reflection Global Digital Elevation Model (ASTER G-DEM) and LANDSAT 8 is presented in the study. This model can be a cost-effective, quick and less labor-intensive tool for assessing erosion in small watersheds. It can also act as a vital input for the primary assessment of environmental degradation in the region, and can aid the formulation of watershed development planning strategies. The Palar River, which drains into Shanmukha Nadi, is a small mountain watershed. The town of Kodaikanal, a popular tourist attraction in Tamilnadu, forms part of this sub-watershed. This quaint, hill-town has been subjected to intense urbanization and exhaustive changes in its land use practices for the past decade. The consequence of this change is manifested in the intense environmental degradation of the region, which results in problems such as increased numbers of landslides, intense soil erosion, forest fires and land degradation. The nature of the terrain, high precipitation, and intense agriculture exponentially increase the rate of soil erosion. Spatial prediction of soil erosion is thereby a valuable and mandatory tool for sustainable land use practices and economic development of the region. A comprehensive methodology is employed to predict the spatial variation of soil erosion using the revised soil loss equation in a geographic information system (GIS) platform. The soil erosion susceptibility map shows a maximum annual soil loss of 3345 Mg·ha−1·y−1, which correlates with scrub forests, degraded forests, steep slopes, high drainage density and shifting cultivation practices. The erosion map shows that the central region is subjected to intense erosion while the inhabited southern part is less prone to erosion. A small patch of severe soil loss is also visible on the eastern part of the northern fringe. About 4% of the sub-watershed is severely affected by soil erosion and 18% falls within a moderate erosion zone. The growing demand for land and infrastructure development forces the shift of urbanization and agriculture to these less-managed spaces. In light of this scenario, the spatial distribution of erosion combined with terrain and hydro-morphometry can aid in sustainable development and promote healthy land use practices in the region.

Lulc Change

Remote sensing and G.I.S help acquire information on changing land use and land cover (LULC), and it plays a pivotal role in measuring and monitoring such local and global changes. The present analysis has been executed on Landsat 5 TM, 1989 and Landsat 8 OLI/TIRS, 2020 images of Pachhua Dun, including Dehradun & Mussoorie urban agglomeration. The present study aims to detect the land encroachment or area of change; rate of change and monitoring spatio-temporal variation in LULC change between 1989-2020 using change detection technique, supervised maximum likelihood classification, and Overall accuracy & Kappa Coefficient (K) was applied as an accuracy assessment tool. The results derived from the change detection analysis exhibits that the highest growth rate was recorded in built-up areas +247.75% (110 km2) and revealed the annual rate of change of 3.55 km2. or  7.99%, the highest among all LULC class during the overall study period of 31 years. The result also found that among all LULC class, the most significant LULC conversion took place from agricultural land to built-up areas followed by open/scrubland and vegetation/forest cover; approximately 69.9km2 of the area under agricultural land was found to be converted into built-up areas. At the same time, 38.9 km2 area of vegetation/forest cover and 36.3 km2 of the area of open/scrubland have converted into agricultural land. Rising anthropogenic influence and unsustainable land-use practices in the study area have led to a large-scale human encroachment and rapid transformation of the natural landscape into the cultural landscape. This analysis provides the essential long-term Geospatial information related to LULC change for making optimum decision-making process and sustainable land-use planning in the Pachhua Dun-Dehradun District, Uttarakhand, India.
