Studies on Land Resource Inventory for Agricultural Land Use Planning in Northern Transition Zone of India through Remote Sensing and GIS Techniques

Land suitability analysis is a prerequisite to achieving optimum utilization of available land resources. Hence, a study on land resource inventory for agricultural land use planning was conducted in the Northern Transition Zone of India to determine land capability and develop a suitability map for wheat and sorghum-based on physical and climatic factors of production using remote sensing and GIS techniques. Detailed soil survey information was used for this exercise. Four series (Singhanhalli, Mugli, Bogur and Venkatapur series) were identified and mapped into seventeen mapping units. Land capability classification showed that a greater portion of the study area belonged to class III followed by class IV with limitations of erosion, wetness and varying soil properties. Four land capability classes viz., II, III, IV, and VI, and seven subclasses viz., IIsf, IIItsf, IVs, IVt, IVts, IVtsf and VIt were identified. Major limitations of these subclasses were slope, erosion, depth, texture, coarse fragments, pH, organic carbon and base saturation. Soil suitability assessment revealed that the soils are moderately suitable to permanently not suitable. About 234 ha (31.6%) is moderately suitable, 494 ha (65.0%) marginally suitable and 10.2 ha (1.3%) permanently not suitable for wheat;while 78.5 ha (10.3%) is moderately suitable, 633.4 ha (82.3%) marginally suitable and 32.6 ha (4.3%) permanently not suitable for sorghum respectively. The moderate, marginal and permanent non-suitability was due to moderate, severe and very severe limitations respectively. However, it is possible to achieve potential yield of the crops in the study area if these limitations are addressed.

COCKPIT-PLUS:A proposed method for rapid groundwater vulnerability-driven land use zoning in tropical cockpit karst areas

Karst groundwater is highly vulnerable to contamination,which urges better land use zoning.This paper proposes a new approach,called COCKPIT-PLUS,to minimize groundwater contamination within cockpit karst regions.The method employed four parameters:P(the existence of ponor/swallow hole),L(lineament density),U(sinking stream to an underground river),and S(distance to spring/pumping site).These parameters are essential for identifying contaminant pathways and transport from the surface to the karst groundwater/springs.COCKPIT-PLUS has been developed and validated in the Gunungsewu karst in Java,Indonesia.This research considers a cockpit as a single hydrological unit that uniquely recharges karst groundwater.We analyzed 2,811 cockpits and 81 other closed depressions to develop a land use planning map.The research used the time to first arrival(Ta),time to peak(Tp),and Q_(max/min)ratio parameters of two karst springs and two underground pumping sites for validation.Cockpits with ponors/swallow holes,sinking streams,high lineament density,and short distances to springs are vulnerable to groundwater and thus must be restricted areas for any land uses.The findings show that though the COCKPIT-PLUS uses a limited karst dataset,the proposed method seems reliable enough for a rapid land-use zoning approach in cockpit karst areas.

Land Use Capability and the Sustainable Scale: An Overview of Agriculture in São Paulo State, Brazil

Establishing a sustainable scale in natural resources management enables effective economic and ecological policies and guarantees the long-term sustainability of economic production. In agriculture, land evaluations determine the land use sustainable scales, that is, those that avoid land degradation and allow the provision of food, wood, energy, and ecosystem services over time. The paper assessed São Paulo State’s agricultural sustainability by analyzing the current land use adequacy to the land use capability map that follows FAO 1976 “guide for land evaluation” and was applied to São Paulo by the State Agricultural Secretariat. Results indicate inefficiencies in land use at the state level, where more than one-third of agricultural lands do not satisfy technical land capability indications. According to technical land use capability, more than 4.5 million hectares are being underused (economic inefficiency) and another 2.2 million hectares are being overused (environmental inefficiency). Pasturelands represent the most unsustainable land use, where 3.7 million hectares are allocated in high quality lands with high agricultural production potential, and another 0.7 million hectares are allocated in lands with very low quality for agriculture, most of than area degraded. To achieve sustainability, lands with high agricultural production potential should be used to improve agriculture and food production and, on the other hand, lands with very low agricultural production potential should be used for wood production, agroforestry, ecotourism and natural ecosystems conservation. Our results provide a framework for improving land use policies in São Paulo State and highlight an opportunity to achieve land use sustainability.

Soil Health and Sustainable Land Resource Management Practices at Municipal Level: A Case from Bheri Nagarpalika (Municipality), Jajorkot District, Nepal

The increasing challenges of pressure and ever-growing demands on limited resources in Nepal by diverse actors,land degradation,biodiversity loss and climate change require the rational use of land resources to sustain and enhance productivity and maintain resilient ecosystems for achieving the sustainable and efficient use of resources,taking into account biophysical and socioeconomic dimensions.Regarding this,Nepal Government has realized and taken initiation of scientific and sustainable land use zoning following the National Land Use Act 2019(2076 B.S.)to use land resources in practicable and sustainable manner.Using spatial information techniques such asZ-3 satellite image,remote sensing(RS),global positioning system(GPS)and geographic information system(GIS).Multicriteria decision making(MCDM)methods for acquiring spatial/temporal data,through expert judgment techniques based on field observation as well as laboratory analysis result,it was found that the soil nutrient status of,the municipality varied spatially and has pH with very high acidic to slightly alkaline but most of the soils are slightly acidic(39.58%).Majority of the soil are loam and sandy loam type with very low to high level of organic matter.Most of the municipal area is under medium range of organic matter.Nitrogen content ranges from very low to very high level as to same ranges of phosphorous(37.69%).Potassium level is also in very high to low as 37 percent land area has high level of potassium.Reclamation of acidic soil mainly in leachable soil is recommended with the proper management of Nitrogen with addition of organic matter is needed to manage for improving crop production.

Measures for Management of Land Use Master Plan Released

On May 8,2017,the Measures for Management of Land Use Master Plan was released for enforcement by the Ministry of Land and Resources.The Measures clearly points out that a land use master plan is an essential part of the national spatial planning system and an important basis for implementing land use modes control and management,

Land suitability assessment for apple(Malus domestica)in the Republic of Korea using integrated soil and climate information,MLCM,and AHP

Apples(Malus domestica)are one of the major fruits cultivated in South Korea and worldwide.To both sustain the productivity of apple trees and preserve the land,a land suitability assessment has been conducted.Two methods were used to analyze land suitability,a Most-Limiting Characteristic Method(MLCM)and an Analytic Hierarchy Process(AHP)with integrated soil and climate information based on the FAO classification framework.The most-limiting characteristic analysis showed that almost all areas were classified as marginally suitable(S3)or not suitable(N),which together accounted for 94.54%of the land in the Republic of Korea.On the contrary,AHP showed that S1(34.1%)and S2(44.17%)account for the majority of the land.

Pathways towards the integration of periurban agrarian ecosystems into the spatial planning system

Introduction:The potential of periurban agrarian ecosystems is recognized as one of the cornerstones for improving urban sustainability;however,this potential has been disregarded in spatial planning and decision making.The main goal of the PAEc-SP project was to assess the feasibility of integrating periurban agricultural areas into spatial planning by developing a viable ecosystem services-based methodology.Methods:The research unfolded along three axes:i)mapping ecosystem services in periurban areas,distinguishing between the current state and the future potential by applying a set of indicators;ii)analyzing the regulatory framework,identifying gaps in the consideration of agrarian ecosystem services;and iii)analyzing the perceptions of these areas held by local actors.Provisioning services(food)are widely recognized by actors and plans,but this leads to weak protection.Results:Cultural services(identity,recreation)are also recognized by all actors and addressed by local urban planning,though this is not connected to farming practices.Regulating services(CO_(2) storage,water quality)are barely addressed by spatial planning and actors do not value them either.Supporting services(biodiversity)are mostly associated with natural areas.Most technicians are reluctant to changes,while new farmers and civil society demand a new holistic approach.Conclusion:The reluctant attitude to change of some actors and the inadequate understanding of ecosystem services,render it imperative to adopt a comprehensive approach through a participatory process of urban planning.Mapping ecosystem services,calculations,and graphs are a valuable communication tool both in discussing the consequences of the loss of agrarian ecosystems with different actors and in planning future scenarios.

“Three-Plan Integration”: Exploring the Order and Regulation Capacity of Spatial Planning

China's spatial planning system has a tradition of prioritizing vertical control over horizontal coordination, which leads to conflicts among various plans for one area. This has brought many problems to the spatial management of Chinese cities. Since socio-economic development plan, urban-rural plan, and land use plan are the three major elements of China's spatial planning system, conflicts among them can be taken as an intensified case of the system's problems, and the practice of three-plan integration should focus on bridging the gaps and solving conflicts among them, so as to eventually eliminate predicaments to China's spatial planning. Currently, due to influences of the actual law and governance systems, threeplan integration is largely a sort of government-led planning coordination dedicated to urban-rural spatial development. In the context of China's constantly deepened political and economic system reforms, three-plan integration, together with the extended multi-plan integration, will surely play an important role in the construction and exploration of China's spatial planning system.

2009—2018年毛乌素沙地圆形农田发展及其对土地规划的启示

The Mu Us dune field in China has become a focal region for research of the prevention and control of desertification.Agricultural practices in this area have been modernized in recent years,evidenced by the development of Center Pivot Irrigation(CPI)farmlands.However,the impacts of CPI farmlands on combating desertification remain poorly understood.This study chose the southeastern part of the Mu Us dune field as a study area to investigate the variations of CPI farmlands from 2009 to 2018 and the influencing factors.The results showed growth trends in both the number and the area of these CPI farmland units over the period.The areas of meso-and micro-scale CPI farmland units stabilized over time to mainly 0-0.2 km2 and 0.2-0.4 km2,respectively;Topography,temperature,and geological substratum were preliminarily identified as the major natural factors driving the development of the CPI farmlands.Within the context of varied stakeholders,the potential for soil erosion,and damage to natural vegetation,the current study suggests that strict management of CPI farmland is required through effective long-term planning and land-use policies.The results of this study can assist in realizing the sustainable development of agriculture and its ecological significance in dune field areas.

Spatial resource allocation via extremal optimization enhanced by cell-based local search

A new treatment is presented for land use planning problems by means of extremal optimization(EO)in conjunction to cell-based neighborhood local search.EO,inspired by self-organized critical models of evolution has been applied mainly to the solution of classical combinatorial optimization problems.Cell-based local search has been employed by the author elsewhere in problems of spatial resource allocation in combination with genetic algorithms and simulated annealing.In this paper,it complements EO in order to enhance its capacity for a spatial optimization problem.The hybrid method thus formed is compared to methods of the literature on a specific resource allocation problem by taking into account both the development and the transportation cost.It yields better results both in terms of objective function values and in terms of compactness.The latter is an important quantity for spatial planning and its meaning is discussed.The appearance of significant compactness values as emergent results is investigated.
