Adaptation to Climate Change in the Pastoral and Agropastoral Systems of Borana, South Ethiopia

Agriculture in Ethiopia is an important economic sector upon which the majority of Ethiopians depend for food, feed and income. However, the sector is dominated by smallholder agriculture. The smallholder sub-sector is predominantly comprised of subsistence and traditional rainfed systems which exhibit vulnerability to various internal and external pressures. Vulnerability within these agricultural systems can be broadly attributed to a variety of climate and non-climate factors which include bio-physical, socio-economic and political elements.

Assistance to enable these smallholders to successfully adapt to future climate change in locally relevant ways can be usefully informed by the analysis and better understanding of past and ongoing adaptation. The study employed farm household surveys, focus group discussions, expert consultations and secondary data collation to obtain both quantitative and qualitative data. The farm household survey employed a multi-stage sampling technique involving selection of five districts and twenty pastoral/agropastoral associations. The study employed a combination of Pressure-State-Response (PSR) framework to analyze how climate change put pressure on pastoral and agropastoral farming systems and livelihoods, and Pelling’s (2011) typological framework to analyze local adaptation responses.

Results showed that pastoral and agropastoral households, their communities and institutions adopted a wide range of adaptation options primarily through adjusting their farming practices and diversifying into non-pastoral livelihoods. The smallholders primarily pursued a resilience approach to adaptation with short term goals intended to avoid system disruptions instead of long-term transformational approaches that significantly address the root causes of vulnerability. A range of barriers constrained local adaptive capacity and shaped routes for adaptation.

In conclusion, smallholders in the Borana lowlands, at least in the foreseeable future, will continue to depend on rainfed agriculture as a primary source of livelihood for which they face considerable uncertainty due to prevalent climate perturbations and eroded ability to adapt. And climate change adaptation responses must be integrated into policies and development programs to actively promote local livelihoods and help reduce vulnerability addressing the shortcomings of conventional adaptation and development pathways.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Location Optimization of a Coal Power Plant to Balance Costs against Plant’s Emission Exposure

Fuel and its delivery cost comprise the biggest expense in coal power plant operations. Delivery of electricity from generation to consumers requires investment in power lines and transmission grids. Placing a coal power plant or multiple power plants near dense population centers can lower transmission costs. If a coalmine is nearby, transportation costs can also be reduced. However, emissions from coal plants play a key role in worsening health crises in many countries. And coal upon combustion produces CO 2 , SO 2 , NO x , CO, Metallic and Particle Matter (PM10 & PM2.5). The presence of these chemical compounds in the atmosphere in close vicinity to humans, livestock, and agriculture carries detrimental health consequences. The goal of the research was to develop a methodology to minimize the public’s exposure to harmful emissions from coal power plants while maintaining minimal operational costs related to electric distribution losses and coal logistics. The objective was...

Evaluation of the Safety and Efficacy of Continuous Use of a Home-Use High-Frequency Facial Treatment Appliance

At present, many home-use beauty devices are available in the market. In particular, many products developed for facial treatment use light, e.g., a flash lamp or a light-emitting diode (LED). In this study, the safety of 4 weeks’ continuous use of NEWA TM , a high-frequency facial treatment appliance, every alternate day at home was verified, and its efficacy was evaluated in Japanese individuals with healthy skin aged 30 years or older who complained of sagging of the facial skin.  Transepidermal water loss (TEWL), melanin levels, erythema levels, sebum secretion levels, skin color changes and wrinkle improvement in the facial skin were measured before the appliance began to be used (study baseline), at 2 and 4 weeks after it had begun to be used, and at 2 weeks after completion of the 4-week treatment period (6 weeks from the study baseline). In addition, data obtained by subjective evaluation by the subjects themselves on a visual analog scale (VAS) were also analyzed. Fur...
