Multi‐Sited Governance of Large‐Scale Land Acquisitions: Mapping and Evaluating the Terrain

Recent spikes in commodity prices, the growing appetite for primary commodities among emerging economies, growing interest in biofuels and speculations over future returns to land and its products have led to a renewed interest in farmland in the global South. With highly publicized risks and polarized “win‐lose” narratives, so‐called “land grabbing” has become an important focus of transnational governance activity. In juxtaposition to those seeing large‐scale land acquisitions as inherently risky or undesirable, some argue for the potential opportunities they engender—provided risks can be mitigated through improved governance. This paper explores this argument through a systematic analysis of the formal features of the multi‐sited governance mechanisms in place to guide agricultural investment and govern its social and environmental effects. The intent is not to discount the importance of informal norms and practices or the so‐called “lived experience of governance,” nor the argument that such land acquisitions are inherently flawed irrespective of the “discipline imposed on them.” Rather, the paper aims to explore the merits of the arguments advanced by the pro‐investment camp, and to explore the extent to which the emerging global governance architecture is set up to deliver on the purported benefits of large‐scale agricultural investment. Results suggest that serious weaknesses in the substantive scope, reach and/or implementation mechanisms in all of the reviewed governance mechanisms pose a serious risk to the likely effectiveness of the emerging governance architecture in minimizing risks and leveraging benefits. Addressing these weaknesses is an obvious first step for bolstering the credibility of those advocating that governance is the solution.     

Advocacy Coalitions in Ontario Land Use Policy Development

In 2005, the Ontario government passed the Places to Grow Act and the Greenbelt Act, both major changes in land use policy designed to preserve greenspaces and combat urban sprawl in the Greater Golden Horseshoe, Canada's largest conurbation. This article examines the actors, actor beliefs, and inter‐actor alliances in the southern Ontario land use policy subsystem from the perspective of the Advocacy Coalition Framework (ACF). Specifically, this paper undertakes an empirical examination of the ACF's Belief Homophily Hypothesis, which holds that inter‐actor alliances form on the basis of shared policy‐relevant beliefs, creating advocacy coalitions. The analysis finds strong evidence of three advocacy coalitions in the policy subsystem—an agricultural coalition, an environmentalist coalition, and a developers' coalition—as predicted by the hypothesis. However, it also finds equally strong evidence of a cross‐coalition coordination network of peak organizations, something not predicted by the Belief Homophily Hypothesis, and in need of explanation within the ACF.

Land and Water Institutions in the Blue Nile Basin: Setups and Gaps for Improved Land and Water Management

This study undertook an assessment and gap analysis of the institutional arrangements for improved land and water management in the Tana and Beles Sub‐basins highlands of the Blue Nile Basin. We explored the mandates and design features of the major land‐ and water‐related institutional arrangements. Focus group discussions, key informant interviews, and a literature review were used in the analysis. The results of our work reveal that a lot of progress has been made in creating an institutional framework for improved land and water management and the policies and laws hitherto developed reflect global policy changes consistent with the widespread adoption of the integrated water resources management (IWRM) principles. There are also cases where informal institutions replace formal institutions. Judged by their enforcement, the water resources management, pollution control standards, and regulations and land use rights are not enacted effectively because of poor enforcement capacity. Overall there is a tendency to focus on command‐and‐control type policies. There is a need to strengthen traditional institutions by drawing lessons from their strengths and establish the legitimacy of these institutions. There is also a need to improve formal policy design, developing policies with specific objectives, goals, targets, and overall institutional changes and resources through active adaptive management to maximize the level and effectiveness of institutional learning. Finally, more focus needs to be given to incentive‐based policies through increased use of positive incentives and more emphasis needs to be given to self‐enforcement rather than third‐party enforcement.     

Transaction costs and inter‐jurisdictional cooperation: an application to land use collaboration

• The costs and benefits of inter‐jurisdictional cooperation and how these impede strategic alliances among jurisdictions is an issue of growing importance worldwide. The reason is the potential cost savings, efficiency increase and economic development benefits that can be realized through cooperation. The literature has increasingly mentioned transaction costs as obstacles that mitigate cooperation and as a key component of cooperation costs, which must be outweighed by cooperation benefits in order for communities to perceive advantageous strategic alliances. However, a framework is lacking in the literature for evaluating the implications of transaction costs for inter‐jurisdictional cooperation. This paper develops a framework for evaluating the nature and dynamics of transaction costs and their implications for inter‐jurisdictional cooperation, with an application to land use. A simple cost function model is used to explain the costs and challenges associated with managing coordinated, cooperative or consolidated relationships, and the dynamics of such costs. The analysis highlights the importance of such things as degree of complexity, inter‐party diversity and the relative sizes of collaborating partners. An application to land use cooperation in Michigan suggests that policies to eliminate transaction costs could help reduce the barriers to cooperation of various types.

Eliciting preferences for land use alternatives: A structured value referendum with approval voting

This article discusses an experimental application of the Structured Value Referendum (SVR) with approval voting. The decision context is selecting the best land use for an undeveloped area of publicly owned suburban land in Richmond, British Columbia. Subjects were a random sample of 200 registered voters, selected in a "mall‐intercept" format. Subjects reviewed relevant information, completed a ballot, and then completed a survey about their satisfaction with the approval voting format. The results are of substantive interest for the land use decision, and show a high preference for an approval voting format. The results show ease in understanding the task and information provided, as well as a belief that this approach could be useful in guiding public policy. © 1999 by the Association for Public Policy Analysis and Management.     

Democracy and socialism

This paper shows that Marx's theory of agricultural rent is not an adjunct to his theory of capital at the level of distribution but is inseparably developed from it. The forms of differential and absolute rent are shown to correspond to the formation of market value and price of production in the agricultural sector respectively, these in turn depending upon the barriers posed by landed property to intensive and extensive cultivation. In appendices, Marx' critique of Ricardo's theory of rent, differential rent on the worst land, a critique of other interpretations of Marx, and the ‘historical transformation problem’ are each considered briefly.     

Measuring dynamic collaborations: Collaborative health assessment tool

The changing nature of organisations in the public sector means that collaboration has become an imperative for many. Notwithstanding considerable scholarly agreement about factors contributing to successful collaboration, a broadly accepted model of collaborative practice has not coalesced. In this paper, we put forward an augmented collaboration assessment tool. Building on existing research, we argue that systems thinking can help us better account for the dynamic and multidimensional nature of collaboration – a process in which partner organisations are interconnected and organised in a way that seeks to achieve a common purpose that they could not have achieved alone. We tested the validity of our tool using a three‐stage, iterative mixed‐methods approach. Our research confirms the value of a diagnostic tool to assist collaboration partners navigate an often uncertain terrain. It further establishes the value of our tool in illuminating a collaboration's dynamic interactions as a means to evaluate ‘collaboration health’.     

The Political Epistemology of Science-Based Policy-Making

Improving the use and impact of science-based policies and practices at the national and transnational level is important for enhancing the quality and legitimacy of democratic governance systems. The purpose of this paper is to provide an overview of the major drivers behind strengthening the creation, application and mediation of scientific expertise for policy-making. Science-based policy-making can take different forms, such as evaluation of practices, implementation of independent or commissioned research, application of quantitative and qualitative analyses, or the development of statistical and environmental monitoring systems. However, scientific evidence is only one among several factors contributing to sound democratic decisions. Scientific expertise needs to be mediated through a complex process of social and political deliberation. The paper aims to identify the main policy challenges behind science advisory bodies and to set out an agenda for rebuilding public trust in science-based policy-making.     

Retaining agricultural activities under urban pressures: A review of land use conflicts and policies

From a national perspective it is unclear whether the continued expansion of urban development seriously affects America's potential food production over the long run. Yet there are clearly regional biases toward conversion of farmland to urban uses and locally important changes in the appearance of the landscape at the rural—urban fringe. Urbanization also generates spillover effects causing the idling of farmland and the shifting from one type of agriculture to another.Land use controls aimed at directly addressing the use of the land may be effective in preventing some conversion of farmland to urban uses but the methods are costly and possibly very complex. Incentives to farmers to keep land in agriculture are generally too weak to be effective in retaining agricultural land in the face of strong urban pressures.This research was supported by a grant from the National Science Foundation (Research Applied to National Needs) to the Regional Science Research Institute.     

Retracting suburbia: Smart growth and the future of housing

Abstract

Metropolitan areas throughout the United States increasingly experience sprawl development. States such as Oregon and Maryland have enacted land use legislation that curbs sprawl by promoting denser urban growth. Smart growth, a new method of metropolitan development leading to more compact regions, offers an alternative to sprawl. Given that housing comprises a major share of the built environment, policies that promote denser residential development form a key component of smart growth.

This article provides an analytic review of the ways housing can be used to support successful smart growth policies. It focuses on three areas: the market for higher density housing, land use issues associated with denser housing development, and methods for financing higher density and mixed‐use housing. The literature on the link between smart growth and housing remains underdeveloped. We offer this synthesis as a way to advance the state of knowledge on smart growth's housing dimension.     

Impacts of China's Rural Land Policy and Administration on Rural Economy and Grain Production

The distinctive changes in China's rural land policy and administration have exerted significant impacts on China's rural socioeconomic development and grain production, either positively or negatively. This article reviews the changes of China's rural land policy and administration in the recent 5 decades. After the land reform accomplished in 1952 and the people's commune system implemented during 1952–1978, China adopted a house responsibility system, which was proven to be effective for increasing grain output and peasants’ income. Yet, it preserved the urban–rural dichotomous economy, formed in the people's commune era, which placed agriculture in a secondary position. The low efficiency in agricultural production and the small‐scale household management, under the current rural land policy and administration, stimulated the transfers of agricultural laborers to the nonagricultural sectors and cultivated land to urban land. Grain production and cultivated land protection in China are conducted most times under the political mandates rather than the economic guidance. Although the previous rural land policies and the strict residence registration helped China to avoid problems prevailing in prime cities of other developing countries, compulsorily asking peasants to grow more grain and to stay in their native land resulted in outstanding social injustice, vulnerable grain production systems, and poverty in rural areas. There are also outstanding conflicts among the interests of central government, local governments, collectives, and peasant households. More flexible rural land policies and more strict cultivated land administrations could be solutions for improving the profitability of grain production and protecting the rapidly declining cultivated land. Compensations for the low profitability in grain production are also needed to encourage an increase in grain output and rural economy.     

Socio‐economic Considerations in Biosafety and Biotechnology Decision Making: The Cartagena Protocol and National Biosafety Frameworks

Article 26.1 of the Cartagena Protocol on Biosafety left open the possibility for member countries to include in their biosafety regulatory processes the assessment of socio‐economic considerations. Countries may also decide to include such assessments as part of their national legislation or regulations for the approval and deliberate release into the environment of genetically engineered technologies. Countries are debating if and how to implement assessment of socio‐economic considerations. This paper contributes to the ongoing policy dialogue by discussing issues related to socio‐economic assessment including scope, timing, inclusion modalities, methods, decision‐making rules and standards, and the integration of socio‐economic assessments in biosafety and/or biotechnology approval processes. This paper also discusses the implications of such inclusion for technology flows and public and private sector R&D. If inclusion is not done properly, it may negatively impact technology flows especially from the public sector and render an unworkable biosafety system.     

Leveraging Administrative Data to Better Serve Children and Families

The challenge of complex social issues drives the need for data systems that can connect information across multiple service delivery systems. Integrated data systems provide significant value for needs assessment, program planning, policy decision making, and collective impact evaluation across a range of social issues. This case study describes a mature county‐based integrated data system. The case study has three aims: (1) to highlight the value of integrated data systems to research, (2) to outline common challenges that such initiatives face, and (3) to present several ongoing considerations for the field that could inform policy recommendations to facilitate the use of integrated data. The authors present examples from the experience of developing this integrated data system, including involvement in the design and evaluation of the first county‐level social impact bond. The case study highlights the benefits and limitations of integrated data use in research and the potential to advance evidence‐based social decision making.     

From Rhetoric to Blueprint: The Moran Review as a Concerted,Comprehensive and Emergent Strategy for Public Service Reform

On 3 September 2009, Prime Minister Rudd announced a six‐month Review of Australian Government Administration. He appointed an Advisory Group chaired by Terry Moran, Secretary of the Department of Prime Minister and Cabinet, to prepare a discussion paper, oversee a benchmarking study and consultations, and craft a blueprint to reform the Australian Public Service (APS) in order to deal with future governance challenges. The vision is to develop a forward‐looking, innovative, collaborative, citizen‐focused, agile, informed and highly‐skilled APS to advise and deliver policy and services for government. Ahead of the Game, a comprehensive Blueprint for action, was released on 29 March 2010. This article provides a high‐level review of motivations and process for the Moran Review, an overview of the Blueprint, an assessment of the strategy and process, and suggestions for moving forward on selected issues.     

Local effects of the new land rush: How capital inflows transformed rural Russia

Rising global prices for agricultural commodities have led to the inflow of capital to rural economies and to transfers of land ownership to new agricultural operators (NAOs) in developing and post‐Soviet countries. How capital inflows affect rural communities is often explained with the variable of institutional strength, an explanation aligned with the good governance approach to economic development: Capital inflows have positive developmental effects, if strong domestic institutions vet land deals and regulate NAOs. Contra the focus on institutional parameters as exogenous variables, this article highlights the role of political projects in shaping local outcomes and driving institutional change. Evolving political priorities are important to understand domestic rural transformations because they lead to interventions that privilege some actors as agents of change, while others are sidelined—hence transforming local economies. This theoretical suggestion is based on a study of Russia's rural transformation that followed a significant influx of capital.     

Regulatory impact assessment and regulatory governance in developing countries

Regulatory impact assessment (RIA) offers the means to improve regulatory decision‐making and practice. RIA involves a systematic appraisal of the costs and benefits associated with a proposed new regulation and evaluation of the performance of existing regulations. So far, the adoption of RIA has been confined mainly to OECD countries. The purpose of this article is to assess the contribution that RIA can make to ‘better regulation’ in developing countries. Results from a survey of a small number of middle‐income countries suggest that a number of developing countries apply some form of regulatory assessment, but that the methods adopted are partial in their application and are certainly not systematically applied across government. The article discusses the capacity building requirements for the adoption of RIA in developing countries, in terms of regulatory assessment skills, including data collection methods and public consultation practices. The article also proposes a framework for RIA that can be applied in low and middle‐income countries to improve regulatory decision‐making and outcomes. Copyright © 2004 John Wiley & Sons, Ltd.     

The management of institutional innovation: Lessons from transferring the land grant model to India

The US and India collaborated on a successful institution building programme in the 1950s and 1960s to develop capacity for agricultural education, research and extension. This paper analyses that process for lessons that might bear on efforts to build similar institutions in other countries. India was an especially favourable environment due to the sophistication of its scientific base, the openness of its leaders to institutional innovation, the presence of public sector enterpreneurs to mobilize support for reform, and a food crisis that made it urgent to find new technology. The US did not fund institutional changes that had little demand in India, but it did influence Indian preferences over the long run by creating several mechanisms to exchange information about the American land grant system. These exchange mechanisms enhanced India's capacity for agricultural science and, less often noticed, contributed to the political support essential to new institutions.     

Federal housing policy and preservation: Historical evolution,patterns, and implications

Abstract

This paper considers the evolution and patterns of federal low‐income¹ housing policies and programs over roughly the past half‐century. It begins with an overview of the multifaceted involvement of the federal government in housing — only one aspect of which is its intervention in the low‐income sector. This is followed by an overview of federal low‐income housing policy from the New Deal to today. The underlying assumptions and approaches of these policies are then considered with respect to such considerations as the government's presence and role, its targeting of assistance, and the selection of subsidy levels and vehicles. The paper concludes with a brief review of the implications of the historical record for future policy.
