Introduction: Forests form a major component of the carbon (C) reserves in the world's ecosystems. However, little is known on how management influences C stocks of woody vegetation, particularly in dry areas. We developed regression models for two dominant tree species to predict C stocks and quantified the potential of community managed forests as C sinks. Methods: Plots were randomly selected from community-managed natural forest, herbivore exclosures, and from communal grazing land. Tree and shrub biomass were estimated using a regression model on the most dominant woody species while herbaceous biomass was determined using destructive sampling.Results: The simplest model, based on only one single predictor variable, showed a good fit to the data for both species (Juniperus procera and Acacia abyssinica). Diameter at breast height (r 2 > 0.95) was a more reliable predictor than height (r 2 > 0.54), crown diameter (r 2 > 0.68) (p < 0.001). The C content of the total biomass for the managed natural forest and the exclosure were estimated as, 58.11 and 22.29 Mg ha −1 , respectively, while that for the grazing land was 7.76 Mg ha −1 , and the mean carbon content between the three land uses were significantly different (p < 0.05). Conclusions: We conclude that forests managed by the community have a high potential for C sequestration and storage and their conservation should be promoted.

Climate change is one of the most serious impediments to agricultural prosperity in Ethiopia, especially where livestock is concerned. In particular, rural farming communities in the drylands of the Afar region are severely exposed to the impacts of climate change, with stark reminders from repeating droughts followed by crop failure and livestock decimation. Locals have a long history of applying adaptation measures to maintain their sustenance. However, a growing literature challenges whether these traditional methods can continue to sustain local livelihoods. This study identifies how pastoral, semi-pastoral, agro-pastoral and mixed-farming communities in Afar perceive and adapt to climate change and whether these practices have brought about any improvement in farm income. A panel data set of five years was gathered using structured questionnaires from a sample of 313 households. Household heads pointed out indicators to identify climate-related stress such as erratic rainfall, drought, temperature change, drying of water sources, prevalence of diseases and lack of human and livestock feed. A fixed effects quantitative model on the panel data was estimated to verify the effect of adaptation strategies on income of household heads. We found that the main adaptation strategies that significantly influenced household income levels were forage production (hay and straw), access to water sources, livestock diversification and migration. The implication is that people severely affected by climate change and living in a situation demanding urgent solutions can actively apply various adaptation strategies if the strategies are linked to the creation of sustainable income benefits. Thus, integrated approaches comprising adaptation methods and expected benefits are an important way to induce farming communities to address challenges related to climatic change.

Introduction: Exclusion of grazing animals and tree plantations were among the methods used for the restoration of degraded lands in tropical semiarid areas. Exclosures can foster secondary forest succession by improving soil conditions and modifying microclimate for understory growth. This paper compared the arbuscular mycorrhizal fungi (AMF) spore density, root colonization of woody plants and soil chemical properties under exclosure with increasing age, and grazing land at different slope positions. Methods: The study was conducted in northern Ethiopia from 12 exclosure sites paired each with adjacent grazing land in total from 24 sites with four treatments replicated three times. In the entire study, 216 plots were examined of which 108 were in exclosures and 108 in communal grazing lands. There were four age classes and three slope positions in each of the land uses. Composite soil and root samples were collected using nested plots measuring 100m 2 from four sides of 1763 plants for spore enumeration and root colonization. Soils for chemical properties were collected from the four corners and center of 5 m × 5 m plots. Results: All the 61 woody plant species that belong to 41 families were colonized by AMF. Spore density and root colonization were significantly higher in exclosures as compared to grazing land and increased with increasing ages of exclosures. Foot slope had significantly higher spore density and root colonization than middle and upper slopes. Soil chemical properties were significantly higher in the exclosure, oldest age of exclosure, and foot slope position (except P). AMF spore density and root colonization were significantly positively correlated with soil chemical properties.

Background Contraception allows women to realize their human right to decide if and when to have children and helps people to attain their desired family size. Yet 214 million women of a reproductive age in developing countries who want to avoid pregnancy are not using a modern contraceptive method. Women who have recently given birth are among the group with the highest unmet need for contraception. Therefore, this study was aimed to assess the prevalence of postpartum family planning use and associated factors among postpartum women in Southern Ethiopia. Methods Institution based cross-sectional study design was conducted. A structured and pretested interviewer-administered questionnaire was used to collect the data from study participants. Study participants were selected using a systematic random sampling technique by allocating proportionally to each health facility. The data was entered using EPI data version 3.1statistical software and exported to Statistical Package for Social Sciences version 22.0 for further analysis. Both bivariate and multivariate logistic regression analyses were performed to identify associated factors. P values < 0.05 with 95% confidence level was used to declare statistica significance. Result Overall, 44% of postpartum women utilize postpartum family planning. Having an antenatal care visit [adjusted odds ratio (AOR) =1.89(95%CI, 2.42–7.90), having planned pregnancy [adjusted odds ratio (AOR) = 1.17(95%CI, 1.60–2.28)], being married (adjusted odds ratio (AOR) =2.86(1.94–8.73), and having a college and above level educational status (AOR) =1.66(1.28–3.55) were significantly associated with utilization of postpartum family planning. Conclusion This study showed that the prevalence of postpartum family planning was 44%. Marital status, educational status of mothers, the status of pregnancy, and having an antenatal care follow-up during pregnancy were some factors associated with postpartum family planning utilization. Therefore, strengthening family planning counselling during antenatal and postnatal care visits, improving utilization of postnatal care services and improving women’s educational status are crucial steps to enhance contraceptive use among postpartum women.
