The role of foreign investment in Ethiopia’s smallholder-focused agricultural development strategy

Recent foreign agricultural investment in Africa has generated a great deal of interest and criticism, with western media warning of a neo-colonial ‘land grab’. This paper moves beyond this narrow assessment by examining the political and social dynamics of foreign agricultural investment in Ethiopia, a country that has figured prominently in recent debates. The paper links macro-level analysis regarding the types of projects and their role in the Ethiopian economy to case studies of investments at the micro-level, which examine changing patterns of land use and implications for displacement, employment and technology transfer. The paper concludes that the expansion of foreign investment in Ethiopia is part of a government move towards an export-led development strategy. As such, macro-benefits in terms of increased foreign exchange earnings come at the cost of increased micro-level risks to those living near new investments, in particular, politically marginalised pastoral populations in remote regions

The Political Economy of Social Policy and Agrarian Transformation in Ethiopia

This thesis is concerned with social policy during structural transformation, focusing on the case of Ethiopia. The thesis takes a realist, case-based approach to the study of social policy, which recognises that political actors construct the domain of 'social' policy within legitimising discourses in specific national-historical contexts. Social policy is a key aspect of state-society relations and an inherently political field of study. Consequently, the study integrates analysis of cleavages in domestic society along class and ethnic lines, the role of state organisations and international influences, and their impact on the social policy pronouncements by senior government officials and implementation of those policies on the ground. In the Ethiopian case, this approach highlights the centrality of land to social policy and state• society relations. In particular, state land ownership is a key part of the government's development strategy that aims to combine egalitarian agricultural growth with security for smallholders. Nevertheless, the failure to expand the use of productivity-enhancing agricultural inputs, which constitute key complements to the use of land for social objectives, has led to differentiation in social policy provision along class, gender, age and ethnic lines. Micro-level case studies link the land question to food security, including the Productive Safety Net Programme (PSNP), and processes of agricultural commercialisation, notably the so-called 'global land grab'. A main argument of the thesis is that the Ethiopian government is attempting to manage social processes in order to minimise the social and political upheaval involved in structural transformation, and that social pol icy is a central means by which it does so. The development strategy requires social policies that enable the government to control the allocation of factors of production, necessitating restrictions on the rights of individuals and groups. As such, this strategy is intricately intertwined with political authority.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

The Performance of Natural Flood Management at the Large Catchment-Scale: A Case Study in the Warwickshire Stour Valley

The limited understanding of Natural Flood Management (NFM) performance, especially at large hydrological scales, is considered a critical barrier for the further funding and implementation of these nature-based solutions to the increasing international problem of flooding. The publications of the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report and Environment Agency’s National Flood and Coastal Erosion Risk Management Strategy (NFCERMS) for England have shown that extreme weather, including increased likelihood of high magnitude flood events, will occur and will require more novel management methods. This study focused on the ability of co-designed NFM measures to ameliorate downstream fluvial flooding by attenuating catchment response through a highly spatially distributed network of attenuating and roughening measures. Performance was characterised by the ability of NFM to attenuate flood peaks at different spatial scales across a large (187 km2) dendritic catchment, including the lowering of flood peaks and delaying the time-to-peak. Using a coupled modelling methodology and applying it to the upper Stour Valley, Warwickshire-Avon, UK, a rural response to the application of a set of NFM interventions was developed using the hydrodynamic model Flood Modeller Pro and XPSWMM ©. The method demonstrated a means of incorporating local knowledge in a realistic set of NFM schemes, tested to multiple flood risk scenarios (including climate change). Under frequent, smaller design storm events (e.g., Index Flood (QMED) and 3.3% AEP), flood peaks were lowered across all hydrological scales tested (5.8 km2 to 187 km2). As the design flood event severity increases, impact from upstream NFM attenuation on downstream peak response diminished significantly, especially at the largest hydrological scales. However, even at the largest hydrological scale, delays in time-to-peak were noted, increasing the ability of downstream communities to respond and enact flood preparation activities, thus increasing resilience to potential flooding events. While the benefits were limited to large flood events, the modelling indicated that NFM has the potential to reduce downstream flood risk. However, greater integration of observed data to improve model confidence and reduce uncertainty in modelled events is needed, especially the uncertainty associated with using single peaked design storm events from the Flood Estimation Handbook (FEH). This paper proposes a future Before–After Control–Impact (BACI) monitoring programme that could be integrated with models and applied across non-tidally influenced catchments seeking to empirically test the hydrological performance of in-situ NFM

An Experimental Investigation of the Hydraulics and Pollutant Dispersion Characteristics of a Model Beaver Dam

Beavers have influenced the world’s ecosystem for millions of years. Their dams create ponds and wetlands that provide a large range of hydraulic and ecological benefits to the natural world, including mitigation against flooding and improving water quality. As beavers are now being reintroduced to many parts of the world, it is important to fully understand the impact of their dams on the flow characteristics of the water-courses on which they are built. This paper investigates the relationship between the physical properties of a model beaver dam and its fundamental hydraulics and pollutant dispersion characteristics. The first objective of this paper was to develop a modelling framework to relate discharge to flow-depth for dams with a combination of porous and impermeable sections. The second objective was to utilize a similar framework to predict the down-stream concentration distribution of an up-stream pollution event passing through such systems. The ability to model these parameters for dams with variable lengths of porous and impermeable sections is important as the porosity of beaver dams can vary with depth, depending on which sections are constructed from branches, rocks, or compacted mud. The analysis and modelling developed in this paper show that a single, general relationship can be obtained between discharge and flow-depth regardless of the presence of sections that are both porous or impermeable, provided the relative depths of these sections are known and accounted for. It is also shown that the Nominal Residence Time and the Advection Dispersion Equation can be used to predict pollutant transport in such systems. These two equations have previously been shown to have limitations when applied to some complex systems, so demonstrating they can be applied to a porous dam with combinations of porous and impermeable sections at the relative discharges investigated is noteworthy

Defining recovery potential in river restoration: a biological data-driven approach

Scientists and practitioners working on river restoration have made progress on understanding the recovery potential of rivers from geomorphological and engineering perspectives. We now need to build on this work to gain a better understanding of the biological processes involved in river restoration. Environmental policy agendas are focusing on nature recovery, reigniting debates about the use of “natural” reference conditions as benchmarks for ecosystem restoration. We argue that the search for natural or semi-natural analogues to guide restoration planning is inappropriate due to the absence of contemporary reference conditions. With a catchment-scale case study on the invertebrate communities of the Warwickshire Avon, a fifth-order river system in England, we demonstrate an alternative to the reference condition approach. Under our model, recovery potential is quantified based on the gap between observed biodiversity at a site and the biodiversity predicted to occur in that location under alternative management scenarios. We predict that commonly applied restoration measures such as reduced nutrient inputs and the removal of channel resectioning could be detrimental to invertebrate diversity, if applied indiscriminately and without other complementary measures. Instead, our results suggest considerable potential for increases in biodiversity when restoration measures are combined in a way that maximises biodiversity within each water bod
