“…Different land use/land cover studies for some parts of Ethiopia indicate that croplands have expanded at the expense of natural vegetation, including forests and shrublands [12,66,68,[70][71][72][73][74] while Tekle and Hedlund [75] reported increases in the size of open areas and settlements at the expense of shrublands and forests. Unlike many of the findings in land use/cover studies in Ethiopia, there have been almost no observed changes in the overall amount of area used for agriculture for about the last fifty years with increasing human and livestock population in the Koga catchment resulting in soil degradation due to over exploitation and erosion from the ploughed fields.…”

This study analyzed more than 50 years of land cover and land use changes in the 260 km 2 Koga catchment in North Western Ethiopia. The data used includes 1:50,000 scale aerial photographs, Landsat MSS, TM and ETM images, and ASTER images together with ground truth data collected through field surveys and community elders' interviews. Aerial photographs have high spatial resolution but provide lower spectral resolution than satellite data. While most land use/cover change studies compare changes from different spatial scales, this study applied land use/cover classification techniques to bring the data to a relatively similar scale. The data revealed that woody vegetation decreased from 5,576 ha to 3,012 ha from the 1950s to 2010. Most of the deforestation took place between the 1970s and 1980s, but there is an increasing trend since then. No significant changes were observed in the area used for agriculture that comprises the pastures and crop fields since the 1950s, while there is an enormous increase in the area used for settlement, due to a tremendous increase in population from one point in time to another. The bare lands that used to exist in previous years were found to be totally covered with other land cover/use classes and no bare lands were observed in the study area in the year 2010. Population pressure and land use policies were found to be reasons for the changes in land use/cover while soil degradation,

“…On the contrary particularly in the highlands of Ethiopia in which population pressure is intense resulted for resource erosion and degradation (Grepperud 1996). Likewise, elsewhere in many part of Ethiopian high lands, pressure associated with populations has argued negative implication on forest land, grazing land, barren land, riparian vegetation and farm land (Tekle and Hedlund 2000). It is true to Beressa watershed where rapidly growing of population brought shortage of land, removal of forest cover and soil erosion and land degradation.…”

Analysing the trend of land use/land cover change and its cause and consequence on human livelihoods as well as on the environment is a matter of concern for sustainable development and management of natural resource. Retrospective analysis of land use/land cover dynamics and its driving force has been undertaken using satellite images of Landsat5 TM 1984, Landsat5 TM 1999, and Landsat8 TM 2015 with 30 m spacial resolution for Beressa watershed of Ethiopia. ArcGIS10.2.2 and ERDAS Imagine14 have been used for image processing to produce 6 land uses/land cover classes in the study area. The result of classified image indicated that in the last 3 decades, farm land and settlement area increased @ 71.6 ha/year and 16.8 ha/year respectively. Between 1984 and 1999, forest cover and water body decreased @ 5 ha/year and 0.03 ha/ year respectively but increased @15.6 ha/year and 7.1 ha/ year between 1999 and 2015 respectively. This increase could be possible due to the involvement of local communities to plant trees around their homestead and farm lands. In this program, plantation of indigenous tree species other than eucalyptus (which affect the ecology) was encouraged. The % share of grazing land and barren land has been decreased to 10 and 10.1 % respectively during 1999 that further reduced to 6.1 and 5.2 % during 2015 as against the 12.4 and 13.1 % during 1984 respectively in the Beressa watershed. Rapid population growth demanded more land for cultivation, more trees for domestic fuelwood consumption and more area for settlement had been responsible for drastic change in the land use/land cover change in the last 3 decades in the Beressa watershed. In order to check the loss of area from gazing land and barren land, alternative source income opportunities to the community dwellers may be provided. Therefore, environmental conservation, management and rehabilitation require integrated approach of community development at various levels.

An experiment was conducted on the determination of effective spatial arrangement for intercropping of maize and potato using competition indices at South Wollo, Ethiopia for two consecutive years, 2010-2011. The objective of the study was to determine effective spatial arrangement for intercropping of maize and potato. The treatments were 1 maize:1 potato, 2 maize:2 potato, 1 maize:2 potato (a), 2 maize:1 potato (a), 1 maize:2 potato (b) and 2 maize:1 potato (b). Sole maize and sole potato was used for comparison. JMP 5 (SAS) software's were used to compute the analysis of variance. The combined yield advantages in terms of total land equivalent ratio (LER) and Income equivalent ratio (IER) indices were greatest in the cases of 1 maize:1 potato followed by 1 maize:2 potato (b) intercropping arrangement. Area time equivalent ratio (ATER) values showed an advantage of 75.0% only in 1 maize:1 potato. Effective Monetary advantage (EMAI) index was highest in 1 maize:2 potato (b)followed by 1 maize: 1 potato intercropping arraignments. However, Competitive ratio (CR) values for all crops in all intercropping arrangements were less than one indicating both crops are equally competitive. Based on the this findings, 1 maize: 1 potato followed by 1 maize:2 potato (b) intercropping arrangement gave the highest PRY, LER,ATER, IER and EMAI; and lowest CR value and in turn achieve higher productivity rates of the two crops, which lead to favorably recommend the use and utilization of this system in south wollo. It is recommended that this project was conducted for two years, there was lack of budget and hence this research should be repeated in different agro ecology and spatial arrangement.
