Molla Mekonnen Alemu
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.74043
Abstract:

Environmental development and protection measures such as feasibility studies, land-use planning and soil and water conservation are some of the issues that need to be considered in watersheds management. Apparently, integrated watershed management is emerging as an approach for the sustained development and management of natural resources. The integral enactment of different environmental frameworks, strategies and policies could positively impact watershed- based developmental approaches. Sediment which is brought through water erosion can hamper the proper functioning of waterways as well as the quality of water in dams. Knowhow on soil erosion and the sedimentation process is among the requisites that need to be considered for the control of sedimentation. Other elements like climate, edaphic factors, land management, topography, and land cover, etc. will also determine the sedimentation process. Integrated Watershed Management approach is a worthy approach to manage the ecological, social and economic watershed development challenges in countries like Ethiopia. Thus, this article is intended to assess watershed characteristics that will help to explore the possibilities of reducing sedimentation and its related effects.

Molla Mekonnen Alemu
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.74045
Abstract:

In one way or another, one out of three people are being affected by land degradation. It is estimated that, about every year, 75 billion tonnes of soil material are being lost worldwide as a result of land degradation. Recent findings also showed that about 2 billion hectares of land were severely degraded, in some cases in an irreversible way, all these caused a severe damage to local ecologies as well as contributed a lot for climate change and its associated effects on the wellbeing of humanity. Apart from this, the major portion of most developing countries population are still dependent on the un-mechanized and primitive forms agriculture, livestock production, forestry and fishery, and their livelihood and options for economic development are directly linked to the quality of the land and its resources. The objective of this article is to reaffirm the role of Sustainable Land Management in the process of agricultural development, the main source of livelihood in the developing countries. The paper initially explored the basic concept and principles of sustainable management. Causes of land degradation, the prime challenge of sustainable land management and development are also dealt in detail.

Characterization of Climatic Data for Predicting Growing Period, the Case of Maichew, Northern Ethiopia  [PDF]
Molla Mekonnen Alemu
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102560
Abstract: In terms of improved crop production, knowledge and information of the crops and crop varieties grown in a given area is a better measure of climate, as applied to crop production in that region, than are complete climatic records. Water is the main element of living plant tissues. Water facilitates the movement of nutrients from the soil to the plant roots and upward throughout the plant tissues. It also provides hydrogen as an element of organic materials formed during photosynthesis. The transpiration of water also helps to cool plants during harsh temperature conditions. The effectiveness of a given rainfall for crop production highly depends on the time of the year that it falls along with its intensity. In moisture deficit areas, the deficiency could be overcome by supplementary irrigation and moisture conserving agronomic practices. Apart from this, the use of improved varieties like early maturing crops will also hold a paramount importance to combat such problems. In arid and semi-arid zones, the conservation and efficient utilization of the available scanty rainfall plays a significant role in the whole production system since it can relegate all other factors, including soil fertility, to minor positions. Therefore, knowledge on growing period has a central role in improving crop production. Thus, this paper is aimed at characterizing climatic data for predicting the growing period in the case of Maichew, Northern Ethiopia.

Molla Mekonnen Alemu
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.710112
Abstract: Household energy demand is among the prime problems that cause deforestation. The use of fuel wood in the developing countries of Africa, Asia and Latin America is be-lieved to play a key role for the razing of forests and the degradation of associated biodiversity and other land resources. High population growth, increased energy demand, urbanization, infrastructure development, etc. are among the factors that exacerbate the current rate of deforestation in Ethiopia. This growing demand is also posing a threat to the remaining natural capital and associated wildlife of the country’s national parks. NechSar national park, a jewel in the Rift Valley of Ethiopia is not in different to this threat. The issue is calling for an urgent interference in the provision of environment friendly energy sources, afforestation programmes, raising the level of awareness on climate change, etc. This study is therefore, aimed at exploring the level of household energy demand interference on the woody vegetation of NechSar Park and promoting the use of environment friendly and energy saving technologies in the vicinity of the park area and beyond.

Molla Mekonnen Alemu
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103278
Abstract:
Agroforestry has been practiced for centuries in different parts of the world by making use of indigenous technical knowledge. Since societies have lived for long period of time in a specific area, indigenous knowledge has been transferred from generation to generation by building on new inventions on what has been inherited across years. The practice has served communities to find indigenous medicinal plants; edible fruits, leaves, roots and steam; fuel; feed for livestock; shelter; construction materials; ameliorating micro climates; and many more. The southern part of Ethiopia is endowed with indigenous agroforestry practices that have evolved over years. The agroforestry activities of the communities have enabled to maintain the greenery of the region along with its magnificent contribution towards ecological values, food security and local economic benefits. This study was held in Lante, one of the Kebeles (the smallest administration unit) of Arba Minch Zuriya district of Southern Ethiopia so as to explore the indigenous agroforestry practices along with its present contribution for food security and local economic development. Primary and secondary data were collected by making use of interview questions and review of related literature. Then data were transcribed and analysed by descriptive statistics. Findings of the study showed that home garden, intercropping and livestock based agroforestry practices of the area are contributing a lot in maintaining food security at the household level through the provision edible items from backyard throughout the year. It has also enabled the communities to be empowered economically as they can always find to be cashed and fulfill household needs. Thus, since the case of Lante is a good role model for sustainable agroforestry development, sharing the indigenous agroforestry experience with the rest of the country could have a great impact in building green economy at grassroots levels.

Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1103280
Abstract:
Trees form an important element for the livelihoods of many in different parts of the world. Provision of oxygen to the atmosphere, combating climate change, improving microclimates, soil and water conservation and the support to wildlife are among the social, ecologic and economic values which substantiate their importance to our environment. Eucalyptus known to have more than 700 genus is believed to be a native tree species of Australia. The tree was introduced to Ethiopia during the time of Emperor Minilik. The tree has a strong potential to adapt in various ecological settings and from fertile to degraded lands. Its fast growing nature has also made it to be an economically viable tree species in the country. It is also the major source of fuelwood and construction materials in the country. The tree, however, due to its aggressive growth nature, has its own ecological impact on the environment as compared to other trees. It is known to consume a lot of water deep in the soil strata and has allelopathic effect which suppresses the under-growth in it. A study was done to explore its social, economic and ecological importance in Wolayita Sodo, southern Ethiopia. Interviews and related literature reviews were used as source of information. Data was then analysed through content analysis and descriptive statistics. The findings of the study showed that, the tree has played a lot in transforming the lives of producers economically. Its contribution in satisfying the household energy demands of the locality is also mentioned as one of its major benefits. However, given its wide expansion in the area in a monoculture way could cause for the degradation of other native biodiversity resources of the country. This is also exacerbated by its allelopathy nature that will restrict the opportunities of using intercropping management practices and have a diversified plantation system in a sustainable and friendly to the environment way. Thus, further detailed socio-economic and ecological studies could help to inform policy makers and environmentalists for the design of appropriate management and production strategies of the tree.

Molla Mekonnen Alemu
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103326
Abstract:
Ethiopia’s economy and the livelihoods of its population are highly dependent on agriculture. In spite of the long history of agricultural practice in the country, the sector is still in its traditional subsistence form while the country would have benefitted a lot in transforming the lives of many given the country’s endowment with immense natural resources. Vast and fertile lands, availability of water bodies and the varied agro-ecological suitability could have an impact in securing food at household and national levels. As compared to the earlier times, agricultural production and productivity have showed vast improvement. However, weak market linkages, environmental degradation, land tenure insecurity, increased cost of agricultural inputs, climate change, low level of awareness and other factors are still weakening the performance of the sector. Mechanized plant and animal production, agro- processing, manufacturing, mining, green energy and tourism can be mentioned as the prominent agricultural investment opportunities in the country. As a result of the present Government plan to attract investors, many foreign and local farms and processing industries are popping up in different corners of the country. This paper is, therefore, aimed at assessing the impacts of the current trend of investment on the land-use practices of the country. Literature, reports and observations were used for the compilation of the paper. The findings of the study showed that, many of the ecological and economically valued land resources are being degraded and polluted by the current trends of the investment ventures. The deleterious and negative ecological impacts of the current investment developments from floriculture, tannery and ash producing industries can be mentioned as an example where environmental impact, sustainable use of land resources and land capability issues have not been considered substantially. If not addressed, this may cause for the improper functioning of land resources and the ecosystem services. Therefore, for the actual realization of the intended investment related benefits; thorough review of existing policies and strategies, ensuring the efficient coordinated functioning of concerned institutions and the creation of a proper land-use planning and management instruments need to be considered if the land resources of the country have to be saved from the negative impacts of the current trends of investment.

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103385
Abstract:
Forests are vital land resources as they provide some of the essential goods and services for the sustenance of human life. In many developing countries, local communities still rely on forests as their prime source of energy in the form of fuel wood and charcoal. This phenomenon has also let many men and women to rely on fuelwood collection and charcoal making as their main stay of livelihoods. In line with this, in many instances, forests of National Parks are still going through illegal and immense deforestation actions as a result of the energy demand by the local communities. Nech Sar National Park, a jewel in the Rift Valley region of Ethiopia is also being affected by deforestation as it shares an immediate border with the city of Arba Minch, one of the heavily populated cities in the southern part of the country and heavily relies on the forest of the park for meeting the household energy demand of its inhabitants. This study was done to quantify the amount of fuelwood which comes out of the park and explore the severity and magnitude of the problem. Primary data on the amount of fuelwood were collected from the three major outlets of the park. Questionnaire and interviews were used to collect information from the local communities, the concerned local authorities, the operational and management staff of the park. Every day, an average of 2909 bundles of fuelwood comes out of the park, fuelwood collection being dominated by females. Therefore, alternative energy sources and energy saving stoves, environmental awareness development for the wider community members and the creation of alternative livelihood opportunities should be in place if the precious land resources of the park have to be conserved.

Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103427
Abstract:
Agricultural production systems are believed to evolve through different developmental stages that shaped up its current state. Literatures mentioned that the latest agricultural development seems to have been in Southwest Asia, mainly in the present day Turkey and Iraq area. Agricultural extension efforts in Ethiopia have helped the transformation of productivity and production. It has contributed for reduction of poverty and for the development of the economic and human capitals of the country. This study was conducted to assess the major strengths and limitations of agricultural extension activities in the southern Ethiopia with a major focus on Arba Minch Zuriya district. The study was carried out by involving 78 agricultural communities of the area and 12 representatives of the concerned governmental institutions. The findings of the study have showed as the agricultural extension system in the area is playing a pivotal role in terms of food security, local and regional economic development and the creation of employment opportunities. However, the agricultural extension efforts are also being challenged by the producer’s level of awareness, shortage of rainfall and increased cost of agricultural inputs. Therefore, enhancing the traditional and modern irrigation practices, improved market linkages, creation of the enabling environment to better organize cooperatives and associations could help to increase the significantly impacting agricultural services of the region in particular and the country in general.
