Book excerpt: Agricultural GDP in Ethiopia grew at an average 7.3 percent per year between 2001/02 and 2012/13. Most of this dynamism occurred in the highlands, where high population density and land scarcity begs the question of how future agricultural output can be maintained to sustain the previous decade’s momentum. This paper uses a spatial regression approach to calculate the maximum crop area potential of each kebele in Ethiopia. We find that although the highlands have a greater potential for cropped area, there is little room to expand. A substantial share of the highlands has limited economic potential to expand the land base devoted to agriculture. In fact, many areas may be reaching an environmental threshold that will require the local agricultural land area to contract to maintain the agricultural productivity outcomes realized in previous years.

This book was released on 2019-02-15 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present results of model simulations of maize, wheat, and sorghum yields in Ethiopia through 2085. The analysis draws on climate outcomes from 32 global climate models and an agronomic crop model to estimate effects on the yields of these cereals of expected higher temperatures and, for most of Ethiopia, increased rainfall. The simulation results suggest that climate change will likely have only relatively small effects on average yields of maize, wheat, and sorghum in Ethiopia up to 2055, as agronomic conditions for cultivation of these crops may actually improve in large parts of the country. Nonetheless, yields will need to increase over time to enable cereal production to keep pace with expected demand growth due to increases in population and per capita incomes. Moreover, even if future changes in climate have only moderate impacts on average crop yields in Ethiopia, there is growing evidence that weather outcomes are likely to become more variable in the future, implying that severe droughts and floods may very well have a greater impact on cereal production in the future than in the past.

This book was released on 2007 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This study uses the Ricardian approach to analyze the impact of climate change on Ethiopian agriculture and to describe farmer adaptations to varying environmental factors. The study analyzes data from 11 of the country's 18 agro-ecological zones, representing more than 74 percent of the country, and survey of 1,000 farmers from 50 districts. Regressing of net revenue on climate, household, and soil variables show that these variables have a significant impact on the farmers' net revenue per hectare. The study carries out a marginal impact analysis of increasing temperature and changing precipitation across the four seasons. In addition, it examines the impact of uniform climate scenarios on farmers' net revenue per hectare. Additionally, it analyzes the net revenue impact of predicted climate scenarios from three models for the years 2050 and 2100. In general, the results indicate that increasing temperature and decreasing precipitation are both damaging to Ethiopian agriculture. Although the analysis did not incorporate the carbon fertilization effect, the role of technology, or the change in prices for the future, significant information for policy-making can be extracted.

This book was released on with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been a significant issue since the end of the 20th century, and impacts a variety of economic sectors, primarily agriculture. The negative impacts of climate change on agricultural production are important because agriculture is closely linked to food security. Although they contribute the least to global pollution, it is estimated that African countries will be the most affected by climate variability. Our paper analyzes the impact of climate change on agricultural production in 11 Eastern and Southern African countries (ESA) during the period from 1961 to 2011 and estimates a panel data model for agricultural production using climate variables (e.g., annual precipitation and annual mean temperature) and economic factors (e.g., livelihood, fertilizer use, machinery, agricultural land, and labor) as explanatory variables.

This book was released on 2013-09-13 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highland Ethiopia is one of the most densely populated regions of Africa and has long been associated with both Malthusian disasters and Boserupian agricultural intensification. This paper explores the race between these two countervailing forces, with the goal of informing two important policy questions. First, how do rural Ethiopians adapt to land constraints? And second, do land constraints significantly influence welfare outcomes in rural Ethiopia? To answer these questions we use a recent household survey of high-potential areas. We first show that farm sizes are generally very small in the Ethiopian highlands and declining over time, with young rural households facing particularly severe land constraints. We then ask whether smaller and declining farm sizes are inducing agricultural intensification, and if so, how. We find strong evidence in favor of the Boserupian hypothesis that land-constrained villages typically use significantly more purchased input costs per hectare and more family labor, and achieve higher maize and teff yields and high gross income per hectare. However, although these higher inputs raise gross revenue, we find no substantial impact of greater land constraints on net farm income per hectare once family labor costs are accounted for. Moreover, farm sizes are strongly positively correlated with net farm income, suggesting that land constraints are an important cause of rural poverty. We conclude with some broad policy implications of our results.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis uses several global databases, including soil properties, slope, temperature and precipitation to simulate agricultural land suitability under both current and projected climate from thirteen general circulation models (GCMs) and two emission scenarios, A1B & B1, which represent relatively high and low emission, respectively. Two ensemble methods, Simple Average Method (SAM) and Root Mean Square Error Ensemble Method (RMSEMM), are employed to assemble the regional climate change which attempts to abate the uncertainty involved in global GCM projections. Fuzzy logic, which handles land classification in an approximate yet efficient way, is adopted to estimate the land suitability through empirically determined membership functions of soil properties, slope, air temperature and Humidity Index, and fuzzy rules chosen through a learning process based on remote sensed crop land products. Land suitability under five scenarios, which are the baseline scenario with the present climate and four climate change projections, A1B-SAM, A1B-RMSEMM, B1-SAM, and B1-RMSEMM, is assessed for both global and seven important agricultural regions in the world. The change patterns of climatic factors and land suitability are explored and analyzed. It is found that countries at the high latitudes of north hemisphere are more likely to benefit from climate change, while countries at mid- and low latitudes may suffer different levels of loss of potential arable land. Expansions of the gross potential arable land are likely to occur in regions at the north high latitudes, like Russia, North China and U.S., while shrinking can be expected in South America, Africa, India and Europe. Although the greatest potential for agricultural expansion lies in Africa and South America, with current cultivated land accounting for approximately 20% of the net potential arable land in the world, negative effect from climate change may decline the potential. In summary, climate change is likely to alter the global distribution of potential arable land and further influence agricultural related socio-economic aspects by the end of this century.

Accordingly, Ethiopian coffee industry is potentially at risk due to the negative impact of climate change on suitability of coffee production. Climate change been severely affecting the national income of the country in general and the livelihoods of poor smallholders in particular via undermining coffee yield and quality. Furthermore, several studies predicted that will continue to impact coffee production in the future. Accordingly, a policy measure that enforces and promotes irrigation, mulching, pruning, tree shade management, drought, pests and diseases resistant high yield improved coffee variety development for coffee production is paramount ISBN: 9783346111074
