Water, environment and development

This paper for the most part constitutes the address which was made to the Consortium for International Development at their recent Presidential Symposium at Colorado State University on 30 July 1992. It raises some of the global issues in water resources development and management which are likely to confront the international community in the 1990s and beyond. The issues pose the challenge to institutions involved in the water resources field in both developed and developing countries.     

Economic development and environment

Summary While considerable progress has been achieved in understanding and addressing environmental problems over the last 15 years, it is clear that much still remains to be done. Prominent among the concerns calling for further action are the dispersion of toxic substances from a large variety of sources and uses, the accumulating and widespread effects of air pollution, and inefficient management of the natural resource base needed to sustain future economic development. It is increasingly evident that work on these issues must be addressed in their global context, including the developing world.Mr Erik Lykke took up his duties as Director of Environment for the Organisation for Economic Co-operation and Development (OECD) on 5 November, 1984. He is Norwegian, and comes from the Norwegian Ministry of Environment, where he was appointed Director General when it was established in 1972. Before that appointment he held various posts in the Norwegian Ministry of Foreign Affairs and in the Norwegian Foreign Service, and worked in the Norwegian Embassies in Ottawa and London and the Delegation to NATO.Mr Lykke graduated from the University of Oslo in 1954 (MA in political science, history and sociology) and worked for a short time as a journalist. He was assistant to Mr. Trygve Lie (a former Secretary-General of the United Nations) and Foreign Minister Halvard Lange. He has worked on a number of national committees, dealing with space, nuclear research, research in science and technology, air, acid precipitation, and law of the sea and polar matters.From 1970, up to his appointment as OECD Director of Environment, he was closely involved in the development of Norwegian policy and practice on environmental protection and in international work in this field. He was actively engaged in the preparations for the 1972 UN Environment Conference and the 1972 Convention for the Prevention of Marine Pollution by Dumping from Ships and Aircraft (he was the first Chairman of the Oslo Commission). He was also Chairman of the UN-ECE and OECD Environment Committees, and has led Norwegian delegations to a number of international meetings and conferences.The opinions expressed in this paper are those of the author and do not necessarily represent the views of the OECD or of the Governments of its Member countries.     

Consumption in relation to population,environment and development

The Earth has enough for everyone's need but not for everyone's greed. (Gandhi, 1947). A statement made when the world's population was 45% and global consumption was 25--30% of today's figures.The triad of problems, population, environment and development, is now being joined by a fourth, consumption. In many respects this could prove to be the least tractable of the four interlinked problems, since consumption patterns and expectations are deeply entrenched in most societies and cultures. However, change will come, whether by design or by default. The present consumption--or rather, excessive and wasteful consumption--on the part of rich nations cannot be sustained for environmental reasons alone, as exemplified by the fossil fuel/carbon dioxide connection to global warming. Nor can the present consumption in developing nations--meagre as these levels are for the 3 billion people who account for only 5% of the global economy--climb to levels desired by many if only because of the sheer numbers of their potential consumers. At the same time, it is increasingly the case that in the food sector, as in certain other sectors, over-consumption among rich communities can lead to under-consumption among poor communities. Fortunately, there are many opportunities to relieve consumption pressures, whether through enhanced technology or shifts in lifestyles, both of which can be promoted by a variety of policy initiatives.     

Population change and environment in central and eastern Kenya

"This paper, in compiling a case-study of six districts in Central and Eastern Provinces of Kenya, addresses the two poles of theory regarding population, environment, and economy--restricted growth and degradation versus induced change and intensification. The paper presents data on population change, and explores its relevance for changing patterns of resource use and economic opportunity.... Changes in population density between the 1969 and 1979 censuses are compiled, using regions of agroclimatic potential as surrogates for indicators of economic development.... Trends in urbanization are also analysed, to illuminate the dynamics of rural-urban linkages."     

Environmental planning,ecosystem science,and ecosystem approaches for integrating environment and development

Currently popular concepts such as sustainable development and sustainability seek the integration of environment and development planning. However, there is little evidence that this integration is occurring in either mainstream development planning or environmental planning. This is a function of the history, philosophies, and evolved roles of both. A brief review of the experience and results of mainstream planning, environmental planning, and ecosystem science suggests there is much in past scientific and professional practice that is relevant to the goal of integrated planning for environment and development, but still such commonly recommended reforms as systems and multidisciplinary approaches, institutional integration, and participatory, goal-oriented processes are rarely achieved. “Ecosystem approaches,” as developed and applied in ecology, human ecology, environmental planning, anthropology, psychology, and other disciplines, may provide a more transdisciplinary route to successful integration of environment and development. Experience with ecosystem approaches is reviewed, their advantages and disadvantages are discussed, and they are compared to traditional urban and regional planning, environmental planning, and ecosystem science approaches. Ultimately a synthesis of desirable characteristics for a framework to integrate environment and development planning is presented as a guide for future work and a criterion for evaluating existing programs.     

Population,desertification, and migration

When an imbalance develops between population numbers and the carrying capacity of the land, the persons thereby displaced are referred to as environmental refugees. The utilization of the land beyond sustainability leads to land degradation and ultimately, desertification. The social and political impacts of long-term environmental migration can be distinguished: a) at the site of origin of the displaced persons by the residual population; b) at rural sites of destination within the nation between the new arrivals and preestablished populations; c) in the cities within the nation; d) in the nonindustrialized foreign countries; and e) in the industrialized foreign countries. In the event that an area which had previously been devoted to pastoralism is converted to agriculture, the displaced pastoralists might respond through armed rebellion. In some instances, the disenchanted urban squatters become a politically restive and even a destabilizing force, as occurred in Sudan in the 1980s, especially in Khartoum and Port Sudan. The foreign countries to which many of the displaced persons are migrating are subjected to increasing levels of migrant-induced economic, cultural, and political strains. The growing problems associated with south-to-north migration across the Mediterranean Sea have recently led France, Italy, Portugal, and Spain to enter into a consultative arrangement with Algeria, Libya, Mauritania, Morocco, and Tunisia. All foreign aid to the nonindustrialized countries that attempts to ameliorate the problem of desertification must adopt integrated approaches that: a) address population issues; b) support environmental education; c) provide for the protection of biodiversity; d) encourage participatory forms of local and national government; e) provide opportunities for income generation outside the livestock sector; and f) foster political security and facilitate ecogeographical (subregional) cooperation.     

On accounting for sustainable development and accounting for the environment

Economic sustainability or intergenerational equity entails maintaining social well-being by decisions about investments in different types of assets. Under certain conditions, consumption can be sustained by depleting resources, or various kinds of natural capital, while building up other kinds of capital. Theoretically, the choices involve the use of a set of accounting prices. The question becomes one of finding and implementing accounting prices that express the roles of the various capital goods in achieving the objective of the economy.Hartwick's rule holds that an economy can be sustained if the value of the total, net investment in the economy, evaluated at those accounting prices, is zero. The rule applies to a special, abstract economic model which expresses a social objective different from the discounted-utilitarian objective on which national accounting is based. Different objectives give rise to different accounting prices. Because the prices may not be right, the zero net-investment rule using available national-accounting prices cannot generate a condition for sustaining an economy.Still, environmental accounting is a tool which, used prudently, can make an important contribution to social decision-making. This paper expands upon these ideas by discussing the incorporation of natural resource and intangible environmental costs and benefits into green accounting at the firm as well as the economy level. Common techniques of mine valuation and standard corporate accounting are the bases for this extension to the valuation of and accounting for decisions concerning the environment.

The future of environment and business development in south-east Asia: the situation in Thailand on economic-cum-environmental development

Summary Over the past two decades, since initial establishment of Thailand's National Environment Board by the original National Environmental Quality Act of 1975 (NEQA/75), many lessons have been learned on the complex problems of establishing a meaningful national environmental program in the country. Based on these lessons, a new act was promulgated in 1992 (NEQA/92), which furnishes very substantial powers and financing for planning and implementing such a program. The result has been a marked upgrading and acceleration of the program, but with the realization that the principal problem now is scarcity of the many needed technical skills in the government's Ministry of Science, Technology and Environment, which serves as the Working Arm for the National Environment Board. One of the approaches now being explored is how to make effective use of the private sector to supplement and complement the government's resources.Thailand's goal, from the point of view of the Ministry of Science, technology and Environment, is the continuing sustainable development of Thailand. This means planning and implementing economiccum-environmental development projects, where the investment pays good dividends in both financial earnings and in environmental protection. This will not be easy, because the projects must be suited to the political, cultural, and social as well as the economic realities of Thailand. The common mistake in developing countries of trying to emulate practices developed and utilized in the affluent industrialized countries must be avoided. It is realized that pioneering studies and research, to obtain the planning and design guidelines which will fit the current national development situation, must be undertaken here in Thailand.Mr Kasem Snidvongs is Permanent Secretary to the Ministry. The article is based on his speech to an International Environmental Forum held in Bangkok in January 1996.     

An analysis of the himalayan environment and guidelines for its management and ecologically sustainable development

Summary The impacts of human activities on the bio-geophysical and socio-economic environment of the Himalayas are analysed. The main man-induced activities which have accelerated ecological degradation and threatened the equilibrium of Himalayan mountain ecosystems are stated as: unplanned land use, cultivation on steep slopes, overgrazing, major engineering activities, over-exploitation of village or community forests, lopping of broad leaved plant species, shifting cultivation (short cycle) in north-east India, tourism and recreation. Monoculture in forests, erosion and landslides have resulted in one–third of the total Himalayan land area becoming environmentally derelict. Cold desert conditions prevail in 41,500 km² of north-west Himalayas and are encouraged by traditional pasturalism. The geo-morphological conditions are major factors responsible for landslides which cause major havoc every year in the area. Other physical problems exist, such as eutrophication, drying up of the natural springs, the recession of the glaciers and changes in surface and ground water hydrology. Wild fauna, like musk deer (Moschus mischiferus) and the snow leopard (Panthera uncia), are now under threat partially due to changes in their habitat and the introduction of exotic plant species. Population pressure and migration are major factors responsible for poverty in the hills. The emigration of the working male population has resulted in the involvement of women as a major work-force. This work includes trekking for hours to collect fodder, timber and drinking water in addition to household duties. Guidelines, with special emphasis on the application of environmental impact assessments for the management of the Himalayas, are proposed.Drs Ahmad and Rawat are scientists, and Dr Rai is a research associate, at the Government of India, Ministry of Environment and Forests, G.B. Pant Institute of Himalayan Environment and Development. Correspondence should be addressed to Dr Afroz Ahmad.     

Pleas,plights and environment: Part I

Summary The depletion of the world's natural resources continues relentlessly. Plants and animals alike are being trapped into ever more numerous shrinking pockets, as man advances to incorporate virgin estates into areas of productivity. The immediate consequence of such an all-out attack in the tropical areas of under-developed countries is the destruction of habitats and the likely break-up of food webs. The attendant disastrous effects on the reproduction of species, hence, puts natural selection at a premium. This scenario has distinctly impressed different people in different places. This suggests diverse sensitivity even for causes voiced in public as matters of sheer truism. The study concentrates on the examination of the dialectic nature/nurture controversy to see whether this may account for the state of disharmony recorded between man and nature. Conversion of nature is traditionally considered a realm of the scientific establishment. The study tries to suggest that the humanities cannot be left out in any debate on the interpretation of the environment. The synthesis reveals a blatant refusal of social determinism as causal agent and, with some reservation, projects biological determinism into sharp focus for pertinent consideration. The cautious reconciliation with parts of sociobiological tenets was regarded as inevitable once grasped that will, knowledge, and sensitivity, were interpreted as the foundation of the main teleological argument.Dr Antonio Allem is trained as a plant taxonomist. His research has focused on the collection of plant genetic resources germ plasm. He has recently written (with J.F.M. Valls) a book entitledRecursos Forrageiros Nativos do Pantanal Mato-Grossense, published by the Departamento de Difusão de Tecnologia, EMBRAPA, Brasilia. He has an interest in the taxonomy of cultivated plants and has recently solved the origin of the cassava plant (Manihot esculenta, Euphorbiaceae). Dr Allem is a member of staff of thein situ conservation unit at Centro Nacional de Recursos Genéticos e Biotecnologia da Empresa Brasileira de Pesquisa Agropecuária.     

Ethanol fuels: Energy security,economics, and the environment

Problems of fuel ethanol production have been the subject of numerous reports, including this analysis. The conclusions are that ethanol: does not improve U.S. energy security; is uneconomical; is not a renewable energy source; and increases environmental degradation. Ethanol production is wasteful of energy resources and does not increase energy security. Considerably more energy, much of it high- grade fossil fuels, is required to produce ethanol than is available in the energy output. About 72% more energy is used to produce a gallon of ethanol than the energy in a gallon of ethanol. Ethanol production from corn is not renewable energy. Its production uses more non- renewable fossil energy resources in growing the corn and in the fermentation/distillation process than is produced as ethanol energy. Ethanol produced from corn and other food crops is also an unreliable and therefore a non-secure source of energy, because of the likelihood of uncontrollable climatic fluctuations, particularly droughts which reduce crop yields. The expected priority for corn and other food crops would be for food and feed. Increasing ethanol production would increase degradation of agricultural land and water and pollute the environment. In U.S. corn production, soil erodes some 18- times faster than soil is reformed, and, where irrigated, corn production mines water faster than recharge of aquifers. Increasing the cost of food and diverting human food resources to the costly and inefficient production of ethanol fuel raise major ethical questions. These occur at a time when more food is needed to meet the basic needs of a rapidly growing world population.
