Application of GIS in natural resource management ERASMUS Intensive Program GIS’EM 2013 at Eberswalde Prof. Dr. Jan-Peter Mund University for Sustainable Development, Eberswalde GIS

GIS in NRM Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 2

Concept of the course This course aims at GIS applications and spatial analysis techniques for the analysis of natural resource information, including sources and capture of spatial data. You will characterize, transform, analyze and present results of spatial data; and spatial analysis to solve real-life resource management problems. Students will learn about the concepts of NRM in lecture, will individually apply GIS capacities and will practice the relevant spatial data skills by completing an individual project. The goal is to provide students an opportunity to become proficient in using GIS for environmental problem solving through understanding of how these skills and concepts can be applied to problems in natural resource management. Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 3

Learning Outcomes of this course: Increase hands-on GIS experiences proficiency using up-to-date GIS software to access, manipulate, and present all types of spatial information in a complex GIS project environment. Assess differences between spatial and nonspatial data Value GIS research and spatial information for decision support Design your individual and relevant GIS project Understand the usefulness and limitations of GIS and related analytical techniques Illustrate the impact of scale, projection, and topology on our understanding of the world. Generate maps using existing spatial data and justify a chosen map design Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 4

Working steps and skills Understand how to approach an individual spatial question Develop a clear spatial question Evaluate and obtain data needed to answer the question Assess the appropriate scale at which to answer the question Perform the tasks necessary to answer the question Discuss the impact of scale and topology on your problem/question. Apply basic proficiency using GIS software to access, manipulate, and present spatial information Obtaining and processing individual data including aerial photographs, satellite data and pre-processed statistical data Performing spatial analysis functions in GIS Analyze and solve spatial analysis problems with GIS software Generate maps using existing spatial data and justify a chosen map design Prepare written and oral reports detailing this process and its results.

What’s about Natural Resource Management Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 12

INRM, CBNRM, Biodiv Conservation, CDM NRM INRM CBNRM CDM Resource Natural Resource Management Integrated Natural Resource Management Community based NRM Clean Development Mechanism The total means available for economic and political development, such as mineral wealth, labor force and political capacities. NR Natural resources (economically referred to as land or raw materials) occur naturally within environments that exist relatively undisturbed by mankind, in a natural form. In contrast to RM, INRM is also being promoted with community groups and, in some cases, even with individual farmers through community-based natural resource management of common-property, open-access, and privately owned resources in micro-catchments, typically only 5–50 km2. Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 13

NRM – some definitions Natural Resource Management refers to the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations. Natural resource management is congruent with the concept of sustainable development, a scientific principle that forms a basis for sustainable global land management and environmental governance to conserve and preserve natural resources. Natural resource management specifically focuses on a scientific and technical understanding of resources and ecology and the lifesupporting capacity of those resources. The term Environmental management is also similar to natural resource management. Source: Wikipedia Prof. Dr. rer. nat. Jan-Peter Mund GIS and NRM HNE Eberswalde (FH) 06/03/2013 page 14

NRM – characterization Biotic Biotic resources are obtained from the biosphere, such as forests and their products, animals, birds and their products, fish and other marine organisms. Mineral fuels such as coal and petroleum are also included in this category because they are formed from decayed organic matter. Abiotic Abiotic resources include non-living things. Examples include land, water, air and ores such as gold, iron Renewable resources are ones that can be replenished or reproduced easily. Some of them, like sunlight, air, wind, etc., are continuously available and their quantity is not affected by human consumption Non-renewable resources are formed over very long geological periods. Minerals and fossil fuels are included in this category. Since their rate of formation is extremely slow, they cannot be replenished once they get depleted. Source: Wikipedia Prof. Dr. rer. nat.

Understanding the basic concepts of GIS is a good start of the literature to allow the people who do not have an idea about GIS to know what GIS is. Internet is a very rich source of published papers, journals and technical reports to explore some published works about GIS applications in transportation analysis and planning (GIS-T). Also, the technologies used in this area such as using .

2G1/3G4 GIS TUTORIAL General informaion. What is GIS? The acronym GIS stands for Geographic Information Systems. GIS refers to one of the several software platforms for the capturing, storage, retrieval, analysis and display of geographic spatial data. GIS assigns abstract statistical information to physical geographic elements.
