Productive Efficiency and Its Determinants in a Changing Climate: A Monotonic Translog Stochastic Frontier Analysis

Submitted by Eugenia Leon on

The changing weather patterns and seasonal shifts are negatively impacting agricultural ecosystems and compromising the benefits from production of agricultural goods and services. Such impacts include reduced farm returns, reduced household incomes, increase in poverty levels, and reduction in farm productivity and efficiency. Using three waves of panel data, this study applies a monotonic translog stochastic frontier (SFA) to assess the overall farm efficiency and the influence of climatic factors, agro-ecological factors, and household factors on farm level efficiency.

The effect of climate change and adaptation policy on agricultural production in Eastern Africa

Submitted by Anonymous (not verified) on

We estimate the production function for agricultural output in Eastern Africa incorporating climate variables disaggregated into growing and non-growing seasons. We find a substantial negative effect of within growing season variance of precipitation. We simulate predicted climate change for the region and find a resulting output reduction of between 1.2% and 4.5%.

The Tilling of Land in a Changing Climate: Panel Data Evidence from the Nile Basin of Ethiopia

Submitted by Eugenia Leon on

Empirical studies point to reduced tillage as a means to increase yields and reverse land degradation. A relatively neglected avenue of research concerns why farmers increase tillage frequencies. Using household plot–level panel data from the Nile Basin of Ethiopia, this article applies a random effects ordered probit endogenous switching regression model to empirically investigate the impact of weather events and other conditioning factors on farmers’ choice of tillage intensity and the effect of changing tillage frequencies on differences in farm returns.

Response to climate risks among smallholder farmers in Malawi: A multivariate probit assessment of the role of information, household demographics, and farm characteristics

Submitted by Felicity Downes on

Why do many smallholder farmers fail to adopt what appear to be relatively simple agronomic
or management practices which can help them cope with climate-induced stressors?
Using household and plot level data collected in 2011, we implement a
multivariate probit model to assess the determinants of farmer adaptation behavior to climatic
risks and the relative contribution of information, credit and education on the probability
of adopting specific practices in response to adverse changes in weather patterns.

Governing agricultural drought: Monitoring using the vegetation condition index

Submitted by Anonymous (not verified) on

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

Submitted by Anonymous (not verified) on

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.

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

Submitted by Anonymous (not verified) on

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.

Farmers Prone to Drought Risk: Why Some Farmers Undertake Farm-Level Risk-Reduction Measures While Others Not

Submitted by Anonymous (not verified) on

This research investigates farmers’ cognitive perceptions of risk and the behavioral intentions to undertake farm-level risk-reduction measures. It has been observed that people who are susceptible to natural hazards often fail to act, or do very little, to protect their assets or lives.

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

Submitted by Anonymous (not verified) on

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.
