Abstract/Overview A number of scholars agree that frequent cultivation raises soil bulk density through compaction and destruction of soil structure. However, no research has been conducted to establish how the intensity of farmland cultivated varies with soil bulk density in different physiographic units. High soil bulk density lowers root penetration and seed germination and therefore can be used as a measure of land degradation. Likewise the intensity of farmland cultivated can be used...
Abstract Drought risk management is the function of the national government complemented by the developed systems of governance in Kenya. However, this function is clearly delineated only for institutions and misses the mark in identifying the roles of communities and strategies they apply in building resilience to drought. This paper is part of a two-part series of outcomes of a study in Marsabit county, that looked at community managed strategies that promote drought resilience. Using an e...
This project work titled "Analysis of soil physical properties of gully erosion in Mgboko-umuoria, Obingwa L.G.A, Abia state, Nigeria. Studies the physical effects and causes of gully erosion in Mgboko-umuoria. So many physical properties were determined as causative agents of gully erosion in the study area.
Abstract: Land use and land cover changes have effect on soil fertility, soil organic carbon stock and soil physicochemical properties. To determine the effects of LULC on selected physicochemical properties of soil and soil organic carbon stock (SOCS) a study was conducted in soro district of Hadiya Zone at Shonkola sub watershed under different land use types. Soil samples from 0 to 15 cm and 15 to 30 cm depth were collected from three major land use types; grassland, cultivated land and f...
Abstract: Soil acidity is one of the main factors affecting agricultural productivity in the highlands of Ethiopia. It is one of the problems that decrease the potential of arable lands for crop growth because of high rainfall in highland areas. The purpose of this study was to assess and quantify the extent of soil acidity under different land use systems and to determine the amount of lime required for neutralizing soil acidity in the study area. Three land uses (cultivated, grazing and na...
Abstract: Soil fertility depletion is the major challenge for agricultural production in southeastern highlands of Ethiopia and particular in the study area. Inadequate information on soil fertility status is one of the main constraints for site-specific appropriated soil fertility managements in the study area. The study was conducted to assess soil fertility status and mapping under different land use types along toposequence in Dinsho District of Bale highland Southeastern, Ethiopia. Base...
Abstract: The study was conducted with the objective to evaluate the effect of land use types and soil depth on selected soil physicochemical properties. A total of 24 disturbed and 24 undisturbed soil samples were taken from the depth of 0-20 and 20-40 cm for the determination of soil physicochemical properties. The soil samples were analyzed with standard laboratory procedures and varied significantly (P < 0.01 and < 0.05) among land use types and soil depths. Sand, silt FC,PWP,AWHC,Soil O...
Abstract: Soil erosion has become one of the global environmental hazards that limits the survival of people today and hinders sustainable socio-economic development worldwide. It is most severe in the tropical and subtropical regions of the world, especially in developing countries like Ethiopia. Estimating the extent of soil loss and understanding the spatial distribution of erosion-prone areas are critical for planning and effectively implementing soil conservation measures with limited r...
Abstract: Land degradation and climate change is the global challenge, where their impact is profoundly seen in developing countries including our country (Woolf et al., 2018). The Ethiopian Productive Safety Net Program (PSNP) is one of the national climate smart initiatives (CSI) implemented to address the persistent land degradation and climate challenges in the country. However, the PSNP effect on Land Use Land Cover (LULC) changes and its carbon storage potential is not yet studied at l...
Abstract: The aim of this study was to assess the dynamics of land-use-land-cover change and its effect on the rangeland ecosystem services of Shinile district. Landsat images of 1999, 2009, 2019 were downloaded from USGS earth explorer with a spatial resolution of 30 m and preprocessed and classified by using ERDAS imagine software to identify land cover types. The ground control points were collected from the field to assist the land use-land cover classification. In addition, a key inform...
Abstract: Evaluating the effect of land uses on the soil physicochemical properties and organic carbon stock under different land use types are crucial option for sustainable soil and land management, and fighting climate change by improving soil health and quality. In the Liben District of southern Ethiopia, a study was carried out to investigate the spatial variability of selected soil physicochemical properties and organic carbon stock under different land use types. In total, 81 undistur...
Abstract: Soil salinity problem is predominantly severe in developing countries, particularly in arid and semiarid regions, resulting in short-term damage to people's livelihoods and long-term repercussions on the country's food security. It is also a major challenge in Ethiopia and west Hararghe in particular where small-scale irrigated agriculture is practiced. Against this backdrop, this study was conducted to assess the soil salinity and irrigation water quality in dry season wheat produ...
Abstract: Continuous conversion of land for different agricultural production purpose has resulted in degradation of soil resources. The decline of soil fertility and soil organic carbon stock become notable phenomena in the highlands of Ethiopia. The present study was conducted to analyse and quantify the land use/land cover changes over the periods of 28 years and to investigate the influence of A. decurrens tree-based farming system on selected soil properties and soil organic carbon stoc...
Abstract: In the study area, there was problem of seedling quality because of degraded local soil fertility and competing interest for manure from vegetable, fruit, coffee and kahat producers. The study was focused on determining the most suitable soil amendment for germination and early seedling growth of selected indigenous multipurpose agroforestry tree species. Seedlings were raised in polythene tubes having 10cm diameter and 15cm height and the experimental plots were laid out with eigh...
Abstract: Land degradation is one of the basic problems facing farmers in the Ethiopian highlands and this limits their ability to increase agricultural production and reduce poverty and food insecurity. Even though various soil and water conservation programs and a number of soil and water conservation were introduced to combat land degradation through the ministry of agriculture, on-and-off farm use of these practices remains below expectations in many degraded areas of the highlands of Et...
