Uncertain Outcomes

A model of watershed land-use planning is formulated that improves on existing models by recognizing that land-use decisions have uncertain outcomes and that land uses change over time. Implications of recognizing the distinction between land-use decisions and their uncertain outcomes are discussed. The land-use changes are modelled using a Markov process. Because of the computational difficulties in determining the return associated with the complete range of possible decision sets, a heuristic technique is required. A heuristic search procedure based on stochastic dynamic programming is described.

Detailed Work

Changes in land-use can have an important effect on rates of erosion and denudation. In order to avoid accelerating erosion rates, decision makers in land-use planning require adequate information on the contemporary geomorphological processes and hydrology of areas where modifications in the land-use pattern are envisaged. The first phase in the acquisition of the information is the reconnaissance survey, which shows where and how the erosional status of an area is likely to be affected, and also acts as a foundation on which to base more detailed work in the future.The Solitude area is an active erosional system, dominated by mass movement and fluvial processes. The rate of removal of material is likely to be increased by modifications in land-use which, from other points of view, would be considered entirely suitable for the area. Therefore, if accelerated denudation is to be avoided, projects involving land-use changes should be implemented only by those having an adequate understanding of the mechanism of geomorphological processes operating in the area.

Slope Factor

Damage to forest resources has caused the environmental balance of watersheds (DAS) becomes damaged. It often causes the result of high levels of erosion. One of the land use changes that are currently happening is in Yeh Empas watershed. With this research can be known the proposed land use and appropriate land use planning on Yeh Empas watershed. Erosion prediction using the USLE (Universal Soil Loss Equation) method is to estimate how much the rate of erosion is happening and also to get an idea how good land management actions for the region. The proposed land use determination is using the scoring method by combining the slope factor of the field, the soil sensitivity of erosion, and the intensity of daily rainfall. Soil sampling was done by taking soil samples from a total of 11 samples of soil from the land unit. This research conducted to estimate the rate of erosion, to determines how much erosion can be tolerated in Yeh Empas watershed, and its relationship with the factors that influence it, as well as to determine the proposed of land use. The results of erosion prediction on each unit of land in the research area ranged from 1.75 to 1,254.96 tons/ha/year and has a grade level of erosion from slight to very severe. The result of tolerated erosion ranged from 15.06 to 24.32 tons/ha/year. The value of erosion prediction that exceeded from tolerated erosion value occurs on land units 7, 8, and 9. On that land units required proposed of land use and soil conservation techniques so that the value of erosion prediction could be below from tolerated erosion value. The analysis results of the proposed land use in Yeh Empas watershed, for areas inside the forest is proposed to protected forest (land units 1, 2, 3, 4, 5, and 6) and the management is by planting plants that are adapted to the contour lines of slope. In the areas outside the forest is proposed for annual crop cultivation area (land units 7, 8, and 9)the management with the farming plantation development, high density growing crops and terracing and also for crops cultivation area (land units 10 and 11) management by mulching, cover soil with high density and terracing.

Abstract Increasing population growth is one of the impacts of the growth of a city or district in an area. This also happened in the Cimahi watershed area. As the population grows, so does the need for land which increases the land-use change in the Cimahi watershed. Land-use changes will affect the surrounding environment and one of them is the river, especially river water quality. As a watershed area, there is one main river that is the source of life as well as the Cimahi watershed, whose main river is the Cimahi River. The purpose of this study was calculated the relationship between land-use change in the Cimahi watershed and the water quality parameters of the Cimahi River. The correlation between the two was calculated using Pearson correlation. Water quality parameters can be seen based on BOD and DO values. BOD and DO values are the opposite because good water quality has high DO values and low BOD values. The correlation between land-use change and BOD was 0.328 is in the area of settlements area. In contrast, to DO values, an increase in settlements/industrial zones will further reduce DO values so that both have a negative correlation, which is indicated by a value of -0,535. The correlation between settlements with pH and temperature values is 0.664 and 0.812. While the correlation between settlements with TSS and TDS values are 0.333 and 0.529, respectively. In this study, it can be seen that there is a relationship between the decline in water quality and changes in land use.

Utility Scale

Land-based, utility-scale renewable energy (RE) systems using wind or solar resources to generate electricity is becoming a decisive solution to meet long-term carbon emission reduction goals. Local governments are responding in kind, by adopting their own goals and/or establishing policies to facilitate successful implementations of RE in their jurisdiction. One factor to successful RE development is to locate the most suitable lands, while continuing to sustain land-based economies and ecosystem services. Local governments often have limited resources; and this is especially true for small, land-constrained local governments. In this paper, we illustrate how a standardized RE technical mapping framework can be used by local governments to advance the implementation of RE in land-constrained areas, through a case study in the Town of Canmore, Alberta. Canmore has a limited municipal area surrounded by the Canadian Rockies, along with complex land-use bylaw and environmentally sensitive habitats. This mapping framework accounts for these conditions as it considers theoretical resources, technically recoverable lands, legally accessible lands, and the spatial capital cost of connecting new RE facilities. Different land-use planning scenarios are considered including changing setback buffers and expanding restrictions on development to all environmentally sensitive districts. The total RE potentials are then estimated based on the least-conflict lands. Technically speaking, even under restrictive land suitability scenarios, Canmore holds enough land to achieve ambitious RE targets, but opportunities and challenges to implementation remain. To eventually succeed in its long-term emission reduction goal, the most decisive step for Canmore is to balance the growth of energy demands, land-use changes, and practicable RE development. Mapping systems that can study the influence of land-use planning decisions on RE potential are critical to achieving this balance.

Wildlife Recreation

Achieving optimal use of wildlife resources is a classic problem in natural resource economics. Ciriacy-Wantrup argued that wildlife resources are a case of a fugitive resource for which private property rights cannot easily be defined and therefore government policy may be necessary to obtain optimal use [5, pp. 141–145]. Land use planning is one area of government policy in which limited attention has been given to management of wildlife resources. One reason for the neglect may be the lack of emphasis on estimating the value of wildlife recreation experiences associated with particular land uses. An exception is the work of Martin, Tinney, and Gum [16] who did not look at marginal land use changes but did consider the termination of all cattle ranching in Arizona and its effect on recreational and agricultural economic surpluses.

Spatio Temporal

Frequent land-use changes might produce a large amount of historical data which are valuable for data mining and decision-making. Based on the traditional Whole-state-recording Mode, the Special-state-recording Mode was proposed, focusing on the temporal aspect. This mode could optimize the land use database and reduce redundant change record. It could also improve data rollback and historical backtracking functions. The mode was successfully applied to land use planning in Zhejiang Province.

Land Use Maps

In this study, time series datasets of MODIS EVI (Enhanced Vegetation Index) data from 2002 and 2011 in the Brantas River watershed located in eastern Java, Indonesia were analyzed and classified to make ten land use maps for each year, in order to support watershed land use planning which takes into account local land use and trends in land use change. These land use maps with eight types of main land use categories were examined. During the 10 years period, forested area has expanded, while upland, paddy rice field, mixed garden and plantation have decreased. One of the reasons for this land use change is ascribed to tree planting under the joint forest management system by local people and the state forest corporation.

Land Use Decisions

Purpose – Land use change in the Alpine Regions is dominated by two main factors: a process of re-naturalization and a process of expansion for settlements with the relevant occupation of low-valley areas. The purpose of this paper is to present an overview of land take measures in the Lombardy Alpine context and the recent proposals of spatial planning instruments for land resource management. New solutions to limit soil sealing have to be confronted with qualitative proposals at local scale. Design/methodology/approach – The paper collects different research outputs regarding land take in the Italian Alpine context and carried out by GIS software and tries to show the new methodologies available for limiting and mitigating soil sealing, in accordance with DIAMONT aims. Findings – The paper argues that the data are now available to analyze the problem and new operative methods have to be settled in the recent context of European Union (Soil Sealing Guidelines) to support decision making in planning, suggesting land use allocation and possible ecological compensation. Research limitations/implications – The new qualitative decision models have to be assessed for a better ecological integration in supporting land use decisions. Practical implications – An evaluation of land take at local scale caused by land use changes is a good support in the decision-making process of planning. Originality/value – In this paper a method based on a local scale is reported, which can be used for the specific assessment of land take in order to support land-use decisions.
