    Adaptation to Climate Risk and Food Security: Evidence from Smallholder Farmers in Ethiopia 2015

    This paper explores the impact of climate risk on the adoption of risk decreasing practices and other input choices and evaluates their impact on subjective and objective measures of household welfare (namely net crop income and a food insecurity indicator). The analysis is conducted primarily using a novel data set that combines data from the large-scale and representative Ethiopia Socioeconomic Survey (ERSS), 2011/12 with historical climate and biophysical data. We employ a multivariate probit model on plot level observations to model simultaneous and interdependent adoption decisions and utilize a conditional mixed process estimator (CMP) and instrumental variable (IV) method for the impact estimates. Findings show that there is interdependency between the adoption decisions of different farm management practices which may be attributed to complementarities or substitutability between the practices. Greater riskiness, reflected in the coefficients of variation and higher temperature , increases use of risk reducing inputs such as climate-smart agriculture (CSA) inputs, but decrease use of modern inputs such as chemical fertilizer. Even if higher climate risk does generate higher incentive to adopt, results also confirm the importance of other conventional constraints to adoption that need to be addressed. Yield enhancing inputs such as chemical fertilizer and improved seed are mainly adopted by wealthier households and households having access to credit and extension servic es whereas risk reducing inputs are frequently used by households with lower level of wealth and limited access to credit and households with stable land tenure. Moreover, the CMP and IV estimations showed that the adoption of CSA and modern inputs have positive and statistically significant impacts on the objective measure of food security (net crop income) but no impact is observed for the subjective food security indicator.

    Soil conservation practices to reduce soil erosion
    Terrace Systems

    Soil conservation is becoming increasingly important due to climate change and harmful farming practices. In hilly or mountainous areas, soil erosion is unavoidable due to rain and wind. Terracing is one of the practices used to prevent rainfall runoff in sloping lands for soil and water conservation. Terracing is a method applied to prevent soil erosion due to excessive rainfall and to reduce the formation of gullies. This consist of ridges constructed across the slope to conserve soil, nutrients and increases the soil productivity, as well as reduces flooding and minimizes soil erosion through decreased slope gradient. Terrace systems are widely spread in east and Southeast Asia for rice farming, and in the Mediterranean for the cultivation of vineyards and olive trees. This webinar highlights the benefits of implementing terraces system in agriculture.

    Soil erosion: the greatest challenge for sustainable soil management 2019
    Also available in:

    Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.
