Conservation projects have often been criticised for creating global benefits while causing negative impacts on local livelihoods. Ecosystem services approaches have been seen as one way to change this by focussing explicitly on maintaining ecosystems for human well-being of stakeholders at various scales. However, ecosystem services approaches have often ignored trade-offs between groups of people and issues of power and do not automatically lead to better outcomes in terms of human well-being. Here we report on a study on the impacts of reforestation projects with an explicit focus on human well-being in three communities in southern Ethiopia. We investigated the distribution of services and disservices from reforestation using qualitative methods. Results showed that the services and disservices from reforestation were distributed unequally across space and wealth groups resulting in widespread dissatisfaction with existing reforestation projects despite the explicit focus on human benefits. To improve outcomes of reforestation it is necessary to acknowledge and manage disservices adaptively, include issues of power and make trade-offs transparent.

Land degradation is a major environmental problem in Ethiopia posing serious threats to agricultural productivity and livelihoods. The interactions of numerous socio-economic, demographic, natural, and institutional factors constitute the underlying causes of soil degradation in Ethiopia. However, there exist evidence gaps on the contextual factors that hinder investments on soil conservation among smallholders. Using primary data generated through a stated preference survey among 359 sample smallholder farm households in Southern Ethiopia, this study investigates investment constraints on soil management technologies among smallholders. A random parameter logit model was implemented to estimate the model. Results indicate that smallholders are willing to invest in soil management technologies if appropriate incentive mechanisms, primarily, secured land tenure rights and access to nance are in place. Unfortunately, the prevailing land tenure regime in the country does not allow private property rights on land and smallholders have very limited access to credit. Thus, instituting secure land rights and improving credit access to smallholders should be considered as key interventions to enhance adoption of soil management technologies. The study highlights that policy interventions that incentivize adoption of soil management measures provide not only on-site private bene ts but wider societal o -site bene ts through the provision of multiple ecosystem services.

Agricultural productivity and farm household welfare in areas of severe land degradation can be improved through ecosystem-based interventions. Decisions on the possible types of practices and investments can be informed using evidence of potential benefits. Using farm household data together with a farm level stochastic simulation model provides an initial quantification of farm income and nutrition outcomes that can be generated over a five year period from manure and compost based organic amendment of crop lands. Simulated results show positive income and nutrition impacts. Mean farm income increases by 13% over the planning period, from US$32,833 under the business as usual situation (application of 50 kg DAP and 25 kg urea ha- 1 yr- 1) to US$37,172 under application of 10 t ha- 1 yr- 1 farm yard manure during the first three years and 5 t ha- 1 yr- 1 during the last two years. As a result of organic soil amendment, there is an associated increase in the available calorie, protein, fat, calcium, and iron per adult equivalent, giving the improvement in farm household nutrition. The evidence is substantive enough to suggest the promotion and adoption at scale, in degraded ecosystems, of low cost organic soil amendment practices to improve agricultural productivity and subsequent changes in farm household welfare.

We present a new systems model that encompasses both environmental and socioeconomic outcomes to simulate impacts of organic resource use on livelihoods of smallholder farmers in low to middle income countries. It includes impacts on soils, which in many countries are degrading with long term loss of organic matter. Many farmers have easy access to animal manures that could be used to increase soil organic matter, but this precious resource is often diverted to other purposes, such as fuels, also resulting in loss of the nutrients needed for crop production. This model simulates impacts of different management options on soil organic matter turnover, availability of water and nutrients, crop and animal production, water and energy use, labour requirements and household income and expenditure. An evaluation and example application from India are presented and used to illustrate the importance of considering the whole farm system when developing recommendations to help farmers improve their soils.

Traditional farming systems across much of Sub-Saharan Africa have greater organic inputs near to the homestead than in fields further away. This is likely to produce a fertility gradient that impacts production capacity, and so provides an opportunity to explore impacts of organic amendments on soils. Across 198 farm plots in 69 households in Halaba, Southern Ethiopia, we investigated the influence of different organic input systems on soil properties. The study also examined the influence of household and farm characteristics on the adoption of land management practices and its impact on soil properties. Samples were taken from farm plots located close (300 m) from the homestead, representing different levels of organic amendments. Soils located close to homesteads had significantly greater soil organic carbon, cation exchange capacity and soil nutrient content compared to soil located near and far from the homestead areas. Soil organic carbon concentrations close to the home were 15%, 27% and 45% greater than farm plots located at far from the home in Andegna Choroko, Asore and Lay Arisho kebeles, respectively. Across all sites, the mean soil organic carbon stock ranged from 20.6 t ha- 1 to 84.6 t ha- 1 , depending on the location of the plots with respect to the homestead. Household and farm characteristics also influenced land management practices and soil properties. In some catchments, farm plots managed by female headed households and relatively rich farmers displayed significantly greater soil organic carbon than farm plots managed by male headed and relatively poor households. This was likely due to greater organic inputs in female headed households in areas where men were otherwise engaged in off-farm activities and in wealthier households with greater access to organic manures. Tree cover in farmlands influenced accumulation of soil organic carbon. The results suggest that out-scaling farm management practices that are common around homesteads, such as adding animal manure or household wastes and maintaining tree cover, would help to improve key soil properties and agricultural productivity.
