Exclusion of grazing animals and tree plantations were among the methods used for restoration degraded lands in tropical semiarid areas. Exclosures can foster secondary forest succession by improving soil conditions modifying microclimate understory growth. This paper compared arbuscular mycorrhizal fungi (AMF) spore density, root colonization woody plants chemical properties under exclosure with increasing age, land at different slope positions. The study was conducted northern Ethiopia...
Soil and water conservation (SWC) measures such as stone bunds trenches integrated with fodder species (ISWC) have been implemented to tackle soil erosion in Ethiopian highlands. However, effects of ISWC on aggregate stability (SAS) organic carbon stocks (SOCS) less studied. Fifteen disturbed composite 15 undisturbed samples were collected from cropland sites treated measures, SWC structures alone no (NSWC). Results revealed that mean values index (SI) quotient (SQ) are: 712 for 8 268 6 187...
Abstract Accurate estimation of evapotranspiration (ET) can be affected by cloud change, while cloud‐induced bias errors in ET change remain poorly understood. Here we evaluated seven data sets from satellite microwave and optical models, atmospheric reanalysis land surface models over East Asia. Results showed that although the estimated changes overall well under mild increase, all them had a systematic overestimation (by 73.8%–159.8%) deteriorated capability capturing heavy especially...
With rapid population growth and absence of agricultural intensification, smallholders need more land to grow crops. This resulted in communal grazing conversion cultivated land. study, therefore, aimed at exploring the magnitude its influence on soil properties vegetation cover change. Ecological time line approach was used measure Plants samples were taken from open land, seasonal 6 years old 16 20 Moreover, 95 respondents selected assess their perception subject. Data analyzed using...
Satellite multi-channel passive microwave observations provide valuable information of canopy vertical structure and vegetation water content, while their potential in the simultaneous estimation forest evapotranspiration (ET) gross primary productivity (GPP) has not been explored. This study combined satellite Emissivity Difference Vegetation Indices (EDVIs) from 6.9 to 36.5 GHz with Penman-Monteith (PM), Priestley-Taylor (PT) light use efficiency (LUE) models estimate daily ET GPP over...
Abstract Introduction Pastoralism and agro-pastoralism are the major modes of life in arid semi-arid rangelands. However, rangeland quality quantity rapidly deteriorating due to a number natural human-induced factors, one which is bush encroachment. Little known on how encroachment affects ecosystem functions services expressed terms native vegetation composition structure, status soil seed bank, chemical physical properties, abundance mycorrhiza spores. Methods We assessed woody species 64...
Abstract Conservation agriculture (CA) systems represent a set of three soil management principles: minimarbance, permanent cover and crop rotations ‐ whereas the CA‐based in this study add bed furrow tillage techniques as integral elements CA. Studies on effects long‐term health productivity are rare globally, particularly Ethiopia. This aimed at investigating (2005–2013) influence northern The treatments we used include two types (permanent raised PRB contour furrowing CF) conventional...
