Keita Integrated Development Project
The Ader Doutchi Maggia Rural Development Project (PDR-ADM), better known as Keita Project, is a development project in Keita Department in central Niger. The Project has taken place in four phases, the first starting in 1983 and the most recent beginning in 2003. It was run initially by the Italian government's Italian Development and Cooperation Bureau, as part of its 'Italian Initiative for the Sahel', with significant help from the United Nations. The fourth phase is being run by the UNDP. As of September 2009, the Project has cost approximately US$88 million, with the majority of funding (US$66 million) coming from the Italian government. The main objectives of the Keita Project are to increase food security and reverse desertification in the Ader, Doutchi and Maggia valleys of Keita Department, an area which faced environmental collapse from the 1970s; a secondary objective is to thereby to reduce the high rate of migration from this region to Italy. The methods used have i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Population Growth
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. World human population has been growing since the end of the Black Death, around the year 1350. A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment Of Niger
Niger is a landlocked nation in West Africa located along the border between the Sahara and Sub-Saharan regions. Its geographic coordinates are longitude 16°N and latitude 8°E. Its area is 1.267 million square kilometers, of which 1 266 700 km2 is land and 300 km2 water, making Niger slightly less than twice the size of France. Brief history Niger, which attained independence from France in 1960 was under military regime till 1991. On public demand Gen. Ali Saibou held multiparty elections in 1993 and soon democracy came into effect in 1993. However, political unrest was caused by Col. Ibrahim Bare who staged a coup in 1996, but he later died in a counter insurgency operations by officers of the military establishment in 1999. This was followed by fresh elections for a democratic rule, and Mamadou Tandja assumed power in December 1999. Tandja, who won the elections in 2004 and in 2009, wanted to bring about a constitutional amendment to extend his tenur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rural Community Development
Rural community development encompasses a range of approaches and activities that aim to improve the welfare and livelihoods of people living in rural areas. As a branch of community development, these approaches pay attention to social issues particularly community organizing. This is in contrast to other forms of rural development that focus on public works (e.g. rural roads and electrification) and technology (e.g. tools and techniques for improving agricultural production). Rural community development is important in developing countries where a large part of the population is engaged in farming. Consequently, a range of community development methods have been created and used by organisations involved in international development. Most of these efforts to promote rural community development are led by 'experts' from outside the community such as government officials, staff of non-governmental organizations and foreign advisers. This has led to a long debate about the issue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eolian Processes
Aeolian processes, also spelled eolian, pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets). Winds may erode, transport, and deposit materials and are effective agents in regions with sparse vegetation, a lack of soil moisture and a large supply of unconsolidated sediments. Although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as deserts. The term is derived from the name of the Greek god Aeolus, the keeper of the winds. Definition and setting ''Aeolian processes'' are those processes of erosion, transport, and deposition of sediments that are caused by wind at or near the surface of the earth. Sediment deposits produced by the action of wind and the sedimentary structures characteristic of these deposits are also described as ''aeolian''. Aeolian processes are most important in areas where there is little o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Management
Water resources are natural resources of water that are potentially useful for humans, for example as a source of drinking water supply or irrigation water. 97% of the water on the Earth is salt water and only three percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen freshwater is found mainly as groundwater, with only a small fraction present above ground or in the air. Natural sources of fresh water include surface water, under river flow, groundwater and frozen water. Artificial sources of fresh water can include treated wastewater (wastewater reuse) and desalinated seawater. Human uses of water resources include agricultural, industrial, household, recreational and environmental activities. Water resources are under threat from water scarcity, water pollution, water conflict and climate change. Fresh water is a renewable resource, yet the world's supply of groundwater is steadily decreasing, with depletion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

Natural Resource
Natural resources are resources that are drawn from nature and used with few modifications. This includes the sources of valued characteristics such as commercial and industrial use, aesthetic value, scientific interest and cultural value. On Earth, it includes sunlight, atmosphere, water, land, all minerals along with all vegetation, and wildlife. Natural resources is a part of humanity's natural heritage or protected in nature reserves. Particular areas (such as the rainforest in Fatu-Hiva) often feature biodiversity and geodiversity in their ecosystems. Natural resources may be classified in different ways. Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, air, as well as any living organism such as a fish, or it may be transformed by extractivist in ...

International Development
International development or global development is a broad concept denoting the idea that societies and countries have differing levels of economic or human development on an international scale. It is the basis for international classifications such as developed country, developing country and least developed country, and for a field of practice and research that in various ways engages with international development processes. There are, however, many schools of thought and conventions regarding which are the exact features constituting the "development" of a country. Historically, development was largely synonymous with economic development, and especially its convenient but flawed quantification (see parable of the broken window) through readily gathered (for developed countries) or estimated monetary proxies (estimated for severely undeveloped or isolationist countries) such as gross domestic product (GDP), often viewed alongside actuarial measures such as life expectancy. ...

Scientific Method
The scientific method is an empirical method for acquiring knowledge that has characterized the development of science since at least the 17th century (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) It involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses, via induction, based on such observations; the testability of hypotheses, experimental and the measurement-based statistical testing of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings. These are ''principles'' of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Although procedures vary from one field of inquiry to another, the underlying process is frequently the sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Problem
In science and mathematics, an open problem or an open question is a known problem which can be accurately stated, and which is assumed to have an objective and verifiable solution, but which has not yet been solved (i.e., no solution for it is known). In the history of science, some of these supposed open problems were "solved" by means of showing that they were not well-defined. In mathematics, many open problems are concerned with the question of whether a certain definition is or is not consistent. Two notable examples in mathematics that have been solved and ''closed'' by researchers in the late twentieth century are Fermat's Last Theorem and the four-color theorem.K. Appel and W. Haken (1977), "Every planar map is four colorable. Part I. Discharging", ''Illinois J. Math'' 21: 429–490. K. Appel, W. Haken, and J. Koch (1977), "Every planar map is four colorable. Part II.

Carbon Dioxide Sink
A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide () from the atmosphere. Globally, the two most important carbon sinks are vegetation and the ocean. Public awareness of the significance of sinks has grown since passage of the 1997 Kyoto Protocol, which promotes their use as a form of carbon offset. There are also different strategies used to enhance this process. Soil is an important carbon storage medium. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to intensive farming. " Blue carbon" designates carbon that is fixed via the ocean ecosystems. Mangroves, salt marshes and seagrasses make up a majority of ocean plant life and store large quantities of carbon. Many efforts are being made to enhance natural sequestration in soils and the oceans. In addition, a range of artificial sequestration initiatives ar ...
