Conclusions Glossary Bibliography Biographical Sketch Summary UNESCO – EOLSS Africa is particularly vulnerable to desertification. Two thirds of the continent consists of desert or drylands.SAMPLE The obvious causes of desertificatiCHAPTERSon and deforestation consist of major ecosystem changes, such as land conversion for various purposes, over- dependence on natural resources and several forms of unsustainable land use. However, the issue of desertification is inseparable from social problems such as poverty and land tenure issues. Politics, war and national disasters affect the movements of people and thus impact on the land. International trade policies as well play a part in land management and/or exploitation. -
World Fertility and Family Planning 2020: Highlights (ST/ESA/SER.A/440)
World Fertility and Family Planning 2020 Highlights ST/ESA/SER.A/440 Department of Economic and Social Affairs Population Division World Fertility and Family Planning 2020 Highlights United Nations New York, 2020 The Department of Economic and Social Affairs of the United Nations Secretariat is a vital interface between global policies in the economic, social and environmental spheres and national action. The Department works in three main interlinked areas: (i) it compiles, generates and analyses a wide range of economic, social and environmental data and information on which States Members of the United Nations draw to review common problems and take stock of policy options; (ii) it facilitates the negotiations of Member States in many intergovernmental bodies on joint courses of action to address ongoing or emerging global challenges; and (iii) it advises interested Governments on the ways and means of translating policy frameworks developed in United Nations conferences and summits into programmes at the country level and, through technical assistance, helps build national capacities. The Population Division of the Department of Economic and Social Affairs provides the international community with timely and accessible population data and analysis of population trends and development outcomes for all countries and areas of the world. To this end, the Division undertakes regular studies of population size and characteristics and of all three components of population change (fertility, mortality and migration). Founded in 1946, the Population Division provides substantive support on population and development issues to the United Nations General Assembly, the Economic and Social Council and the Commission on Population and Development. It also leads or participates in various interagency coordination mechanisms of the United Nations system. -

Kramer An abstract of a dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the University Program in Ecology in the Graduate School of Duke University 2008 Copyright by Dalia Amor Conde Ovando 2008 Abstract The construction of roads, either as an economic tool or as necessity for the implementation of other infrastructure projects is increasing in the tropical forest worldwide. However, roads are one of the main deforestation drivers in the tropics. In this study we analyzed the impact of road investments on both deforestation and jaguar habitat loss, in the Mayan Forest. As well we used these results to forecast the impact of two road investments planned in the region. Our results show that roads are the single deforestation driver in low developed areas, whether many other drivers play and important role in high developed areas. In the short term, the impact of a road in a low developed area is lower than in a road in a high developed area, which could be the result of the lag effect between road construction and forest colonization. -

To evaluate the effects of sea level rise on barrier islands and coastal regions, we studied future projections of sea level rise at Ocean City and Assateague Island, Maryland. -
Population Growth & Resource Capacity
Population Growth & Resource Capacity Part 1 Population Projections Between 1950 and 2005, population growth in the U.S. has been nearly linear, as shown in figure 1. Figure 1 U.S. Population in Billions 0.4 0.3 0.2 Actual Growth 0.1 Linear Approximation - - - H L Year 1950 1960 1970 1980 1990 2000 2010 Source: Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. World Population Prospects: The 2010 Revision. If you looked at population growth over a longer period of time, you would see that it is not actually linear. However, over the relatively short period of time above, the growth looks nearly linear. A statistical technique called linear regression can create a linear function that approximates the actual population growth over this period very well. It turns out that this function is P = 0.0024444t + 0.15914 where t represents the time variable measured in years since 1950 and P represents the (approximate) population of the U.S. measured in billions of people. (If you take statistics, you’ll probably learn how to obtain this function.) The graph of this linear function is shown in the figure above. (1) Just to make sure that you understand how to work with this function, use it to complete the following table. The actual population values are given. If you are working with the function correctly, the values you obtain should be close to the actual population values!

Analysis of Habitat Fragmentation and Ecosystem Connectivity within The Castle Parks, Alberta, Canada by Breanna Beaver Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Environmental Science Program YOUNGSTOWN STATE UNIVERSITY December, 2017 Analysis of Habitat Fragmentation and Ecosystem Connectivity within The Castle Parks, Alberta, Canada Breanna Beaver I hereby release this thesis to the public. I understand that this thesis will be made available from the OhioLINK ETD Center and the Maag Library Circulation Desk for public access. I also authorize the University or other individuals to make copies of this thesis as needed for scholarly research. Signature: Breanna Beaver, Student Date Approvals: Dawna Cerney, Thesis Advisor Date Peter Kimosop, Committee Member Date Felicia Armstrong, Committee Member Date Clayton Whitesides, Committee Member Date Dr. Salvatore A. Sanders, Dean of Graduate Studies Date Abstract Habitat fragmentation is an important subject of research needed by park management planners, particularly for conservation management. The Castle Parks, in southwest Alberta, Canada, exhibit extensive habitat fragmentation from recreational and resource use activities. Umbrella and keystone species within The Castle Parks include grizzly bears, wolverines, cougars, and elk which are important animals used for conservation agendas to help protect the matrix of the ecosystem. This study identified and analyzed the nature of habitat fragmentation within The Castle Parks for these species, and has identified geographic areas of habitat fragmentation concern. This was accomplished using remote sensing, ArcGIS, and statistical analyses, to develop models of fragmentation for ecosystem cover type and Digital Elevation Models of slope, which acted as proxies for species habitat suitability. -

Understanding Predation

Bender1 aces.nmsu.edu/pubs • Cooperative Extension Service • Circular 688 The College of Agricultural, Consumer and Environmental Sciences is an engine for economic and community development in New Mexico, improving Figure 1. Predation is a frequently misunderstood ecological process, primarily because people empathize with the prey and confuse the act of predation with the effect of predation on populations of prey. While successful predation re- the lives of New sults in the death of individuals, those deaths may have little or no effect on the population as a whole. (Photo courtesy of L. Bender.) Mexicans through SUMMARY academic, research, Predation is a much misunderstood ecological process. Most people confuse the act of predation with the effect, believing that the killing of an individual and extension animal invariably results in a negative impact on the population (Figure 1). This view is frequently wrong, and ignores the complexity of predation at the individual, population, and community levels. At the individual level, programs. predisposition refers to characteristics (e.g., poor body condition, inadequate cover, disease, etc.) of individuals that make them more or less likely to die from predation or any other cause. Predisposition influences whether (or how likely it was that) an individual would have lived if not killed by a predator. The greater the degree of predisposition, the less likely the death of a pre- dated individual would have any effect on the population. Predisposition is necessary for predation to be compensatory, or substitutive, at the level of the population. -
