CONVENTION ON GENERAL BIOLOGICAL DIVERSITY ENGLISH ONLY ADDIS ABABA PRINCIPLES AND GUIDELINES FOR THE SUSTAINABLE USE OF BIODIVERSITY INTRODUCTION The Annex to this document contains the Addis Ababa Principles and Guidelines for the Sustainable Use of Biodiversity, as adopted in Addis Ababa, Ethiopia, from 6 to 8 May 2003. The Addis Ababa workshop synthesized the outcomes of the three previous workshops on the issue of sustainable use, integrating different views and regional differences, and developing a set of practical principles and operational guidelines for the sustainable use of biological diversity. The resulting Guidelines are still considered to be in draft format until adoption by the seventh meeting of the Conference of the Parties. /… For reaso ns of economy, this document is printed in a limited number. Delegates are kindly requested to bring their copies to meetings and not to request additional copies Annex Addis Ababa Principles and Guidelines for the Sustainable Use of Biodiversity I. BACKGROUND A. Explanation of the mandate 1. In recent decades, biodiversity components have been used in a way leading to loss of species, degradation of habitats and erosion of genetic diversity, thus jeopardizing present and future livelihoods. Sustainable use of components of biodiversity, one of the three objectives of the Convention, is a key to achieving the broader goal of sustainable development and is a cross-cutting issue relevant to all biological resources. It entails the application of methods and processes in the utilization of biodiversity to maintain its potential to meet current and future human needs and aspirations and to prevent its long-term decline.

  • Ecosystems and Biodiversity
    Unit 2: Ecosystem An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations. “Ecosystem is a complex in which habitat, plants and animals are considered as one interesting unit, the materials and energy of one passing in and out of the others” – Woodbury. Organisms and environment are two non-separable factors. Organisms interact with each other and also with the physical conditions that are present in their habitats. ―The organisms and the physical features of the habitat form an ecological complex or more briefly an ecosystem.‖ (Clarke, 1954). The concept of ecosystem was first put forth by A.G. Tansley (1935). Ecosystem is the major ecological unit. It has both structure and functions. The structure is related to species diversity. The more complex is the structure the greater is the diversity of the species in the ecosystem. The functions of ecosystem are related to the flow of energy and cycling of materials through structural components of the ecosystem. According to Woodbury (1954), ecosystem is a complex in which habitat, plants and animals are considered as one interesting unit, the materials and energy of one passing in and out of the others. According to E.P. Odum, the ecosystem is the basic functional unit of organisms and their environment interacting with each other and with their own components. An ecosystem may be conceived and studied in the habitats of various sizes, e.g., one square metre of grassland, a pool, a large lake, a large tract of forest, balanced aquarium, a certain area of river and ocean.

Current address: Institute for Inorganic and Analytical Chemistry, Bioorganic Analytics, y Friedrich Schiller University Jena, Jena, Germany. Received: 23 August 2019; Accepted: 8 November 2019; Published: 14 November 2019 Abstract: Anthropogenic eutrophication has caused widespread environmental problems in freshwater lakes, reducing biodiversity and disrupting the classic pelagic food chain. Increasing our understanding of the exact role of nutrients and physicochemical variables on microbial dynamics, and subsequent microalgal and cyanobacterial blooms, has involved numerous studies ranging from replicate microcosm-based studies through to temporal studies of real lake data. In a previous experimental microcosm study, we utilised metaproteomics to investigate the functional changes of a microalgal-bacterial community under oligotrophic and eutrophic nutrient levels. Here, we analyse the time series data from this experiment with a combination of typically used univariate analyses and a more modern multivariate approach, structural equation modelling. Our aim was to test, using these modern methods, whether physicochemical variables and nutrient dynamics acted additively, synergistically, or antagonistically on the specific biotic community used in the microcosms.

  • Multidisciplinary Nature of Environmental Studies: Environmental Studies Deals with Every Issue Thataffects an Organism
    1 Multidisciplinary nature of environmental studies: Environmental studies deals with every issue thataffects an organism. It is essentially a multidisciplinary approach that brings about an appreciation of our natural world and human impacts on its integrity. It is an applied science as its seeks practical answers to making human civilization sustainable on the earth’s finite resources. Its components include biology, geology, chemistry, physics, engineering, sociology, health, anthropology, economics, statistics, computers and philosophy. `The industrial development and intensive agriculture that provides the goods for our increasingly consumer oriented society uses up large amounts of natural resources such as water, minerals, petroleum products, wood, etc. Nonrenewable resources, such as minerals and oil are those which will be exhausted in the future if we continue to extract these without a thought for subsequent generations. Renewable resources, such as timber and water, are those which can be used but can be regenerated by natural processes such as re-growth or rainfall. But these too will be depleted if we continue to use them faster than nature can replace them. For example, if the removal of timber and firewood from a forest is faster than the re-growth and regeneration of trees, it cannot replenish the supply. And loss of forest covers not only depletes the forest of its resources, such as timber and other non-wood products, but affects our water resources because an intact natural forest acts like a sponge which holds water and releases it slowly. Deforestation leads to floods in the monsoon and dry rivers once the rains are over.

TITLE Knowing The Ecosystem II. PURPOSE Knowing the components of the ecosystem and its position in the ecosystem. III. BASIC TEORY The branch of biology that developed from natural history is called ecology. Ecology is the study of inter actions that take place between organisms and their environment (national geographic, 2004: 36). Mangrove ecosystem has ecological and economic function is very useful. Ecologically, mangrove ecosystem serves as spawning (spawning grounds) and the enlargement area (nursery grounds) various marine organisms such as fish, shrimp, scallops and others. In addition mangrove litter (in the form of leaves and twigs) that fell in the waters after the decomposition process will be a source of feed in the aquatic environment. Nontji (1993) states that the mangrove ecosystem as well, a habitat for berbaga species of birds, reptiles, mammals and type of organic melainnya, so that mangrove forests provide biological diversity (biodiversity) and germplasm of high and serves as a life support system( Wantasen, Adnan S, 2013 : 205). An ecosystem is a system in nature that it occur in the interrelationship between organisms with other organism, as well as environmental conditions (biology lecturer team, 2014: 26). The word ecosystem proposed by A.G. Tansley in 1935, and consists of two words and the eco system. The word eco show environment, and said the system shows a complex system of coordination units.
