Governing agricultural drought: Monitoring using the vegetation condition index

This paper investigates the spatial and temporal aspect of seasonal agricultural drought in Ethiopia during the cropping season using Vegetation Condition Index. SPOT-VGT S10 NDVI time-series for the period 1998 to 2013 was employed. Five hundred and sixty-seven dekadal images were administered in order to produce the multi-temporal agricultural drought maps. Accordingly, the analysis showed different causes for the nation-wide drought events occurred in the years 1998, 2000, 2002, 2009, and 2010.


Estimating the impact of a food security program by propensity-score matching

Reducing poverty and improving household food security remains an important policy objective for rural development in the semi-arid areas of many countries in Africa. Many development programs have been introduced in efforts to bring the cycle of poverty and food insecurity to an end. This paper investigates the impact of a food security package (FSP) program in improving rural household’s food consumption in Tigray region, Northern Ethiopia.


The Effect of Enclosures in Rehabilitating Degraded Vegetation: A Case of Enderta District, Northern Ethiopia

Ethiopia is one of the African countries facing problems of environmental degradation. In particular, the problem is severe in the Tigray region of Northern Ethiopia highlands where, environmental degradation is threatening many parts of the region. Efforts to contain this problem and facilitate natural rehabilitation have been made at several levels. The establishment of area enclosures, and soil and water conservation works are two of the main strategies promoted to contain land degradation and restore the natural vegetation.


Assessing the evidence of climate variability in the northern part of Ethiopia

In semi-arid highlands of northern Ethiopia, episodes of droughts of varying severity and duration occur. The occurrence of these droughts is associated mainly with the seasonal rainfall variability. This study attempts to investigate the temporal and spatial variability of climate parameters, particularly rainfall and temperature for the period 1954-2008. Standardized rainfall anomaly was used to examine the temporal characteristics of climate variability and determine the prevalence of droughts.


Coping with Food Insecurity on a Micro-Scale: Evidence from Ethiopian Rural Households

This article examines the main household demographics and economic factors associated with food insecurity and coping behavior of rural households employed during times of food shortages in northern Ethiopia. Using a cost-of-basic-needs approach we estimated the food poverty line. This cut-off value was used to classify households as either food secure or insecure.


Climate change vulnerability in Ethiopia: disaggregation of Tigray Region

Climate change and variability severely affect rural livelihoods and agricultural productivity, yet they are causes of stress vulnerable rural households have to cope with. This paper investigated farming communities’ vulnerability to climate change and climate variability across 34 agricultural-based districts in Tigray, northern Ethiopia. It considered 24 biophysical and socio-economic indicators to reflect the three components of climate change vulnerability: exposure, sensitivity and adaptive capacity.


Farm Level Adaptation to Climate Change: The Case of Farmer’s in the Ethiopian Highlands

 In Ethiopia, climate change and associated risks are expected to have serious consequences for agriculture and food security. This in turn will seriously impact on the welfare of the people, particularly the rural farmers whose main livelihood depends on rain-fed agriculture. The level of impacts will mainly depend on the awareness and the level of adaptation in response to the changing climate.


Spatial and temporal assessment of drought in the Northern highlands of Ethiopia

With the development of global changes, researchers from all over the world increasingly pay attention to drought detection, and severe droughts that may have resulted from climate change. In this paper, spatial and temporal variability of drought is evaluated based on precipitation data and remotely sensed images. The standard precipitation index (SPI) and vegetation condition index (VCI) are used to evaluate the spatial and temporal characteristics of meteorological and vegetative drought in Tigray, Northern Ethiopia.


Effect of Policy Interventions on Food Security in Tigray, Northern Ethiopia

This study attempts to investigate the effectiveness of government policy interventions at different scales addressed to improve food security. Food security both at the regional and district level was investigated by deriving food balance sheets for the period 2000-2008. An empirical analysis based on a logit model was also employed to analyze household level food security status.
