Designing Blue and Green Infrastructure Networks (BGIN) has been recommended as a potential tool for land-use planning to increase ecosystem services while preserving biodiversity. All municipalities in France are required to perform BGIN planning. This article focuses on the Couesnon watershed (Brittany, France) and the participatory process used to define and analyze five possible pathways of future land-use and land-cover changes that included implementation of BGINs. Impacts on biodiversity were estimated by quantifying the change in landscape connectivity of woodlands, grasslands and wetlands. The effectiveness of BGIN policies was assessed by comparing current landscape connectivity (2018) to those in possible futures. Landscape connectivity referred to functional connectivity for three indicator species (Abax parallelepipedus, Maniola jurtina and Arvicola sapidus) across three landscape features: woodlands, grasslands and wetlands, respectively. Results allowed impacts of urban and agricultural land-use changes to be identified in terms of extent and quality. If BGIN policies were applied effectively to control the expansion of gray infrastructure, they would help increase the area and the quality of grassland and woodland connectivity by no more than 2%. Agricultural land-use and land-cover changes could have more impact on the extent of grassland (?82% to +38%) and wetland (?49% to +47%) connectivity. Current and future trends for hedgerows implied a decrease in woodland connectivity of 9.8–33.8%. Impacts on the quality of landscape connectivity is not proportional with the extent, as a decrease of the latter can have relatively more negative impacts on the former, and inversely. The study highlights that the BGIN strategy can preserve landscape connectivity effectively in urban ecosystems, where human density is higher, but can be threatened by agricultural intensification.

These changes are related to the promotion of competitive and performance-based forms of agriculture. In a context of tense relations between farmers and herders, the quest for equitable access to land, which is a guarantee of peace, stability, and balanced economic and social development, is being called into question by the arrival of capital investors and new actors that are highly supported by the State. This situation raises questions about two important issues: (i) the challenge of the sustainable management of natural resources, especially land; and (ii) the socio-political stakes related to the fact that land is a sensitive resource, both politically and socially. The situation is exacerbated by the fact that dominant discourses are being built around representation of unused and available lands. The aim of this article is to address this controversy by questioning land-use planning processes and tools and underlining the reality depicted. We demonstrate that discourses around land availability are built upon sectoral visions that tend to overshadow the realities of land use. Indeed, livestock farming and particularly its mobile form (i.e., pastoralism) is rendered invisible by not being considered in the majority of land-use and agricultural policies. Through a participatory survey of campsites, we show that gathering basic information on livestock farming should not to be reduced to technical issues. Beyond that, we acknowledge that these land-use issues are rooted in sector-based and neoliberal visions of development. We conclude by discussing the importance of effective decentralization in financial and technical means and the development of systemic proficiency that goes beyond normative sectoral views to acknowledge and act on territorial development.

While the complexity of producing and processing spatial data and the potential for biases are well recognised, the social process of making sense of data and its implications for societal uses is less analysed. In this article, insights of critical data studies are applied to study the production of, as well as uses and misuses of, the Finnish urban-rural classification. The classification structures Finland into three urban classes and four rural classes and offers an alternative to classifications that utilise administrative, municipal, and regional boundaries. The classification acts as a boundary object, functioning as a common reference for parties with varying information needs and interests. Using document analysis, as well as an insider action research methodology and our own experiences as data producers, this article aims to understand the processes of sense-making of data in the context of urban-rural classification and identify ways of improving related information systems and data practices. Intended and realised uses of the classification are analysed in order to identify different ways in which data producers and users make sense of data and justify the utilisation of the classification. The process of sense-making starts from the planning of data production and shapes how data and eventually information system are formulated throughout the data cycle. Communication about the limitations of the classification remains an issue and highlights the nature of sense-making as a collective process wherein users are actively shaping data practices as they translate information systems into their own contexts. This also draws attention to the nature of information systems as inherently unneutral, inevitably affected by negotiations shaped by the various information needs.

We employ a green grab framework to link various actors' operations and various scales operating in communities. To unpack these treatments, we asked two questions: 1) How do various actors negotiate green grabbing to subordinate indigenous land claims to their interests? 2) How do various scales arrange green grabbing to mediate indigenous land claims? In addition to these questions, we try to understand how green grabs are motivated by political networks, labor-capital mobilization, and environmental regulations. This model provides more specific treatments of economy and policy orientations on various scales and more detailed empirical examinations of actor orientations in resource transformations.

Urban development can be considered as a function of strategic behavior of the involved agents, which is affected by various factors such as land use interactions, density of population, economic situation, etc. This study presents an integrated model of cellular automata, multi-criteria analysis, game-theory and agent-based methods for land-use planning and simulation of urban development scenarios based on growth and distribution of the population. This model quantifies and simulates the land-use interactions concerning regulations and guidelines of the master plan. In the proposed approach, the suitability of developed land-use types is evaluated by using the multi-criteria analysis. Land-use changes are defined as an outcome of the interaction between two types of decision-makers (agents): Land Developer and Municipality. Game theory is used to simulate and quantify the strategic behavior of these two agents. The optimal decision between the agents is obtained using the backward induction process. The proposed model was implemented in the region of Roozieh in the city of Semnan. Six scenarios were simulated based on the Semnan's approved master plan and considering the stochastic perturbation. The outcome of each scenario was evaluated based on the spatial equity factors. The results demonstrated the ability of the model to simulate the consequence of urban land-use development plans based on the regulations and guidelines of the master plan, especially for the balanced distribution of services concerning existing demand in their undersupply regions.

In such a context, to explore the evolution of the region is of both political and theoretical interest. This study presents the result of a scenario-building exercise, based on a Delphi method – an interactive forecasting technique – relying upon about 60 practitioners, experts and academics representing 19 Mediterranean countries and a wide range of disciplines and expertise. The present article has three main purposes. First, to identify the main challenges, trends and driving forces that influence the agri-food systems in the Mediterranean over a short (2020) and medium (2030) term. Second, to discuss the alternative policy responses to the challenges that the region will face in terms of water resource management, farming systems and agri-food value chains in terms of desirability and feasibility. Thirdly, to provide informed, evidence-based recommendations that might help different stakeholders to take action in the region's agri-food sector. Based on this Delphi's results, the study suggests that the gap between the countries in the South and the North of the Mediterranean in terms of challenges posed in water management, farming systems and the agri-food value chain is expected to grow. Experts agree that climate change is going to play a key role in the future of both sides of the Mediterranean, but with a differential impact in the sub-two regions. Nutrition-related challenges will exert a growing pressure especially in the Southern Mediterranean countries. A set of desirable and feasible policy option for addressing the Mediterranean food-related challenges are discussed.
查看更多>>摘要:? 2022 Elsevier LtdAn important share of worldwide poverty reduction since the 1970s is due to China's decrease in rural poverty. This article asks how has this extraordinary story of success traveled beyond East Asia, and in particular how the World Bank reflected it. Building on studies of policy narratives, it shows how the Bank has since the 1990s constructed a perspective that aligns China with its broader depiction of “pro-market” East Asia. It downplays the role of the state as subsidizer and buyer of poor people's production and reduces Chinese policies to their land reform component, which then becomes the basis of policy advice extended to transitioning and African countries. The article's main contribution is showing the constitution of a development narrative spanning two decades and reaching the form of an extremely concise and therefore increasingly ubiquitous statement about a “liberalizing China” and the poverty-reducing and market-conforming effect of land reform alone.
查看更多>>摘要:? 2022 Elsevier LtdRecently, though some of the developing countries have been experiencing urbanization at a rapid pace, India is far behind them. Historically, a hefty proportion of India's urban population lived in large cities. However, the latest Census period (2001–2011) showed that small towns (population less than 0.1 million) such as Census towns had contributed around 30 % of the country's urban growth. In the backdrop of this fact, certain questions are pertinent: can the emergence of the small towns be interpreted as the second-best solution in the light of the agglomeration economies; whether different groups are traceable within the category of small towns; which economic factors determine the size and growth of these towns; where are these towns emerging, and what are the major policy initiatives to be undertaken for their development are some of the research questions which are analyzed in this study by considering 7437 small towns in India as per the 2011 census. Using the latest 2011 Census data, our analysis suggests that the small towns are neglected in terms of policy consideration and investment in infrastructural facilities. Cluster analysis is indicative of different groups of small towns. Infrastructure availability and salubrious climate are some of the major determinants of growth of small towns in India. They are emerging in the vicinity of large cities with low variation in distance and population size. Regression analysis also supports these results. It suggests that small towns emerge as large towns reach their saturation points, and the rural to urban transformation takes place rapidly in response to economic development. Finally, policy options are recommended to make small towns more productive in the future and help them contribute to sustainable and higher economic growth.

However, proper management of fundamental geospatial datasets, like land use, determines how well this resource can serve the goals of sustainable development, e.g. achieving inclusive and sustainable urbanization through informed decisions based on up-to-date land use data. Land use data describes the rights to utilize land in accordance with the legal zoning thereof. Allocation of land use rights must align with and give effect to national, provincial and local spatial plans, which means multiple stakeholders are involved in land use regulation. The purpose of this study was to identify and classify the network of stakeholders involved in the land use application process, which results in allocated land use rights. This was done by analysing the South African legal framework for spatial planning and land use management, and to evaluate their a priori influence on this process and on land use data. The results of the stakeholder network analysis can guide the identification of (a) suitable custodian(s) for this fundamental geospatial dataset in the context of the South African Spatial Data Infrastructure (SASDI). Within the SASDI, custodianship is used to ensure availability of good quality geospatial data to empower governments in their planning and decision-making. The average influence of each stakeholder, and as a result their impact on the land use data, was determined based on a classification of roles and responsibilities in the land use application process. The average influence was computed for each sphere of government. The provincial sphere had the highest influence, even though the local sphere has the mandate to allocate land use rights. The national sphere is mainly responsible for strategic direction and implementation support and thus had a significantly lower influence. Based on the results, shared custodianship of land use data in South Africa is recommended among a legislative custodian, coordinating custodians and data custodians. Further research will involve stakeholder representatives to verify the results and to establish multi-stakeholder custodianship roles and responsibilities.
查看更多>>摘要:? 2022 The AuthorsWhile literature on land grabbing and land formalisation respectively has literally exploded the past decade, few studies analyse the practical processes taking place at their confluence, or provide an analysis at an aggregate level. This paper is based on 27 months of in-depth empirical investigation of thirteen large-scale agro-investments across four regions in Tanzania. It explores how four key legislative acts and policies related to land formalisation and land acquisition for large-scale agro-investments unfold on the ground, their implementation and combined effects. We show that land formalisation and acquisition are intrinsically linked: the former paving the way for investment in all thirteen cases. Moreover, rather than fulfilling development policy expectations of land tenure security for smallholder farmers, employment and poverty reduction in rural Africa, we demonstrate that, in Tanzania, these combined processes rather foster village land dispossession, investors’ land acquisitions, and a (re)centralisation of land control. Therefore, we argue that the conjoint implementation of policies associated with land formalisation and land investments have adverse consequences for rural farmers whose land is formalised and then set aside for investment ultimately leading to a formalised rural land dispossession. Our unique aggregate analysis thus provides solid support to the existing critique towards the parallel implementation of land formalisation and large-scale agro-investments, and the interlinked reform of the land legislative framework, all strongly supported by global development bodies.
