Land Degradation and Sustainable Land Management in the Highlands of Ethiopia 12 Land Degradation and Sustainable Land Management in the Highlands of Ethiopia Hans Hurni1, Solomon Abate2, Amare Bantider3, Berhanu Debele4, Eva Ludi5, Brigitte Portner6, Birru Yitaferu7, and Gete Zeleke8 Abstract The Ethiopian Highlands cover over 50% of the country and are home to more than 90% of Ethiopia’s population of over 80 million people (estimate for 2010); 60% of the livestock and 90% of the area suited for agriculture are also located here. Although more than 90% of the Highlands was once forested, today a mere 20% of this area is covered by trees, and the percent- age of forest cover is less than 4%. This is evidence of a high incidence of degradation of vegetation in the past, which has continued to the present. Land-use and land-cover changes have been particularly dynamic in the 20th century, during which climate change also began to have effects; wildlife in natural habitats have been restricted to those few areas that were preserved naturally due to rugged topography or natural aridity. Soil erosion has been severe throughout the Highlands, but mainly on agricultural land; the cur- rent severity and extent of soil degradation seriously threaten food security. In response, a number of soil and water conservation measures have been successfully implemented over the past 35 years in some parts of the High- lands. This is highly encouraging, but greater emphasis must be given to conservation in the coming decades.

KREUTER Department of Ecosystem Science and Management, Texas A&M University, College Station, Texas, USA The goal of this article is to investigate factors influencing conservation-oriented land management practices on land holdings with conservation easements. We report the results of a mail survey that produced responses from 251 out of a total of 518 landowners with a permanent conservation easement on their property. We predicted that landowner satisfaction with their easement and good relationships between land- owners and easement holders would be positively correlated with the amount of conservation-oriented land management practices.

  • Study on the Organizational Structure of Rural Land Stock Cooperative System Based on Game Theory and Network Data
    International Journal of Security and Its Applications Vol. 10, No. 3 (2016), pp.333-344 http://dx.doi.org/10.14257/ijsia.2016.10.3.29 Study on the Organizational Structure of Rural Land Stock Cooperative System based on Game Theory and Network Data Liang Xiao School of economics and management, Suzhou University, Suzhou city, Anhui province, 234000, China Abstract With the development of economy and society, the agricultural land stock cooperation system is a typical system innovation, which has a significant effect on rural production efficiency. In this paper, we research on the organizational structure of rural land stock cooperative system based on game theory; the result shows that the economic performance of land circulation stock cooperative system is much higher than other land transfer mode. At the same time, the mode of joint-stock cooperative system also has high social performance. By using game theory, we find that farmers tend to passively accept unfair treatment in enterprises based on the consideration of individual benefit, so that governments should effectively implement the macro management functions, and make punishment for the behavior of the enterprise managers' untrue disclosure. In order to improve the agricultural land stock cooperation system, the government should make clear the property right of farmland; promote the scale management of agricultural land and enhance the industrialization of rural areas. Keywords: Rural land circulation; Stock Corporation; Scale operation; Empirical analysis 1. Introduction The rural land stock cooperative system is the reform and innovation of the rural land property rights system in China, and it is a kind of land circulation mode which is explored in practice.

    ECOLOGICAL PRINCIPLES FOR MANAGING LAND USE The Ecological Society of Americas Committee on Land Use Key ecological principles for land use and management deal with time, species, place, disturbance, and the landscape. The principles result in several guidelines that serve as practical rules of thumb for incorporating ecological principles into making decisions about the land.

  • Comparative Review of Methods Supporting Decision-Making in Urban Development and Land Management
    land Article Comparative Review of Methods Supporting Decision-Making in Urban Development and Land Management Magdalena Wagner * and Walter Timo de Vries TUM Department of Civil, Geo and Environmental Engineering, Technical University of Munich, 80333 Munich, Germany * Correspondence: [email protected] Received: 3 July 2019; Accepted: 5 August 2019; Published: 7 August 2019 Abstract: This paper discusses how and where technologies supporting decision-making can play, or are already playing, a role in both urban development and land management. The review analyzes and compares three types of technologies: cellular automata (CA), artificial intelligence (AI), and operational research (OR), and evaluates to which extent they can be useful when dealing with various land planning objectives and phases. CA is one of the most useful models for simulating urban growth, AI displays great potential as a solution to capture the dynamics of land change, and OR is useful in decision-making, for example to conduct locational analyses. The evaluation relies on a collection of relevant articles, selected on the basis of both content and actuality. The paper offers new perspectives towards innovative methods in urban planning and land management and highlights where and when which type of tool can be considered useful and valid. The existing gaps, i.e., phases or areas in spatial planning or land management where the methods have not been applied, are also discussed. Keywords: cellular automata; artificial intelligence; operational research; land management; urban development 1. Introduction In today’s fast-moving world, information and communication technologies play important roles in our daily lives, both socially and professionally.

  • Chapter 1 Basic Principles of Decision Making in Natural Resources and the Environment
    Chapter 1 Basic Principles of Decision Making in Natural Resources and the Environment Daniel L. Schmoldt USDA Forest Service, Southern Research Station, Madison WI USA Jyrki Kangas Finnish Forest Research Institute, Kannus, Finland G. A. Mendoza Department of Natural Resources and Environmental Sciences, University of Illinois, Urbana, Illinois USA Key words: Multiple objective decision making, decision analysis, preferences, natural resource management. Abstract: As public land management merges biophysical, social, and economic objectives, management decision criteria become more extensive. Many of these criteria are value-laden, and yet are not easily expressed in monetary terms. Utility theory has traditionally been the decision model proffered by the management science and operations research communities. More recently, however, the analytic hierarchy process (AHP) has also received considerable attention, primarily because it places greater emphasis on the decision makers’ preferences structures. A simple example of the AHP, for college enrolment, illustrates many of the method’s salient features, and some of the underlying mathematics. A brief review of some applications of the AHP in natural resources management is also included. Land management agencies need to establish decision models that provide some structure for how decision-support information is organized and applied, so that decisions are made openly within a well-defined framework. In doing so, decision accountability and justification are achieved concomitantly with the process itself. 1 D.L. Schmoldt et al. (eds.).

INTRODUCTION Early in the beginning of the twentieth century, Gifford Pinchot defined effective natural resource management as “…providing the greatest good for the greatest number, in the long run” (q.v., Pinchot 1947).

  • New Tools for Land Management
    New Tools for Land Management: A Quick Introduction to Ecological Site Descriptions Land management agencies have the job of managing natural resources for multiple uses in a sustainable manner. A sound understanding of ecological process- es is necessary to successfully manage agricultural and wild lands, and develop policy for programs that support management. Spatially variable and complex landscapes can be subdivided and classified into land units that behave similarly, called ecological sites. Ecological site descriptions synthesize the over- whelming amount of scientific information concerning soils, hydrology, ecology, and management into a con- cise document that provides land managers, landown- ers, conservationists and policy makers the information needed to make well-informed decisions.
