Optimal allocation of direct and embodied arable land associated to urban economy: Understanding the options deriving from economic globalization

Land resources do not flow directly but can be allocated as “embodied land” in goods and services during economic globalization. The term “embodied arable land” can help link local land allocation strategies to the global and national supply chains and trade activities, and suggest new lens in optimizing arable land allocation. China is facing a serious arable land shortage, especially in municipal administrative areas. Based on the nested input-output analysis (Nested IOA), this work takes Shanghai as an example, exploring the allocation of direct and embodied arable land of an urban economy within the process of economic globalization. The amount of embodied arable land associated with Shanghai economy is 6.09 Mha, broken down into local arable land use (0.20 Mha), domestic inflows (3.20 Mha) and foreign inflows (2.69 Mha). This area supports local final demand (4.32 Mha), domestic outflows (1.24 Mha) and foreign outflows (0.53 Mha). Land-related imbalances emerge in the study, namely the economy’s demand versus the city’s size, the arable land demand versus supply, and embodied arable land inflows versus outflows. Regarding the role of the urban economy in allocation of global arable land under economic globalization, on the one hand, Shanghai has intensively involved with a large amount of embodied foreign arable land resources, and has been heavy dependent on foreign embodied arable land; On the other hand, there is still large potential for Shanghai to take the opportunity of economic globalization for an optimal allocation of direct and embodied arable land. Policy suggestions on taking the opportunity of economic globalization for an optimal allocation of direct and embodied arable land are put forward.     

The State as Both Regulator and Player: The Politics of Transfer of Development Rights in China

The conventional argument that the introduction of transfer of development rights (TDR) shifts the power of land use regulation from the state to the market is increasingly under challenge. In China, the state's grip on land is reinforced through TDR, in which the state is both regulator and player. This state-dominated form of TDR affects China in three ways. First, competing aspirations of different scales of government complicate how TDR is implemented. Although the central state promotes TDR to maintain a national balance of arable land, some local states instrumentalize it to expand their landed basis of accumulation. Secondly, TDR tends to benefit the state but not its people. It may increase the fiscal income of the sending government and lessen the land shortage of the receiving government, but sometimes at the expense of the interests of land users without land ownership. Thirdly, given the state's deep involvement in TDR programs, the key for China's TDR to protect arable land lies not so much in clear property rights or a fully fledged market as in effective checks and balances regarding the state's powers over TDR. These three observations attest to the embeddedness of TDR in the local political economy.     

The trade-offs between economic efficiency and job creation in olive grove smallholdings

Cooperation among farmers is an effective alternative to reduce production costs in smallholdings of traditional olive groves and increase their low profitability. However, an increase in efficiency reduces working hours and the labour required for the management of farms. This fact can lead to negative effects in rural areas, especially considering the importance of the social aspect of the crop. Therefore, to contribute to the global discussion on the transition towards more sustainable farming, it is important to know, ex ante, what level of employment is generated by olive groves and what could be lost under more competitive and efficient scenarios. The purpose of the work is to quantify the expected impact on employment by the implementation of cooperative management methods in order to generate true and accurate information that can be used in the design of future policies that aim to increase the economic profitability of small olive farms. The results make clear that this way of managing farms, by increasing the efficiency of agricultural work, has a significant negative impact on employment. However, this management formula does encourage the professionalisation of the sector by generating quality employment, in addition to contributing to the preservation of small farms and the socio-cultural and territorial benefits they generate.     

What lies beneath: Climate change,land expropriation,and zaï agroecological innovations by smallholder farmers in Northern Ghana

Large-scale land acquisitions (LSLAs) are increasing in Ghana amid a weak legal and regulatory framework. This paper explores the impacts of this phenomenon on farmer innovations under recurrent environmental changes. Using a case study of zaï, an indigenous innovative farming practice, the paper makes two interrelated arguments. Firstly, it shows that the pervasive enclosures coerced by the Ghanaian state undermine how indigenous knowledge could be proactively deployed for climate risk management. Secondly, LSLAs produce a social barrier to climate change adaptation, as they lead to heightened uncertainty and apprehension among farmers, which affects decisions on climate risk management. More specifically, land expropriation is an example of how adaptation could be hindered by governance, institutions, and policy at the extra-local scale, including not only existing land use laws, but also the constitutional guarantee of private property. The evidence supporting these arguments come from survey data on 619 plots, 70 in-depth interviews, village-level transect walks, and participant observations. Overall, the paper contributes to emerging debates at the interface of land use policy, climate justice, and sustainable adaptation. Theoretically, it also contributes to understanding State-society relations, as well as the political economy of eminent domain, often justified through discourses of “public benefits.”     

Remote sensing-based detection of agricultural land losses around Greater Cairo since the Egyptian revolution of 2011

Over the last four decades, the loss of agricultural land has been observed in Egypt at high rates. However, the highest rates of losses have occurred since the January 25th revolution in 2011. Greater Cairo (GC), which is the largest metropolitan in Egypt, has witnessed a massive loss of agricultural land since the 2011 revolution. However, until now, no study or official report has revealed the volume of agricultural land losses in this region. This study quantifies agricultural land losses around the GC using Landsat satellite images from 2010 and 2018. Supervised classification was performed using the maximum likelihood algorithm in QGIS software. A post-classification comparison method was applied to detect the land use/land cover changes between the classified images; then, the loss of agricultural land was quantified using Arc GIS software. Visualizations of the gains and losses in agricultural land and the spatial trends of agricultural land losses were created using TerrSet software. The results show that 9600 ha of agricultural land were converted to urban use during 2010–2018, which means that the annual rate of agricultural land loss has tripled and now reaches approximately 1200 ha per year. Decay of executive authority, rapid population growth, real estate market speculation and fragmentation of agricultural land were the main driving factors of agricultural land losses during this period. The results of this research may help decision makers understand the current high rate of agricultural land loss. Hence, appropriate strategies may be adopted to prevent future losses of this valuable land.     

A game theoretic approach to optimize multi-stakeholder utilities for land acquisition negotiations with informality

To combat the critical stresses of rising urbanization, the government acquires land from private owners using the power of eminent domain. This land assembly causes negative externalities such as increasing social tension and injustice that may impose a long-term threat to stability and sustainable development. Therefore, there is a need to make the land acquisition process more transparent and just. Considering the unique Indian context where informality has a strong presence, we propose an approach based on game theory that models the bargain through a three-stage Nash equilibrium game. Four agents – the government, the private developer, the landowner, and the free rider – are considered. We provide conditional solutions for the generalizable Case and proceed to model different stakeholder behavior patterns through two utility functional forms – linear and exponential. In the linear case, we find that the free rider obtains half of the revenue of the project, whereas the landowner gains between one-fourth and one-half of the revenue. Thus, we highlight the undeniably crucial role free riders play in land acquisition negotiations. However, closed form solutions cannot be obtained for the exponential form, due to which we use simulations to demonstrate a solution procedure. We conclude by stating that the proposed model can be useful in formulating future land policies in a sustainable and inclusive manner, with optimal utility derivations for all concerned stakeholders. Our model can also be extended to other spatial contexts where informality features heavily in the land market, especially in the Global South.     

Non-income effect of land ownership and tenure on subjective wellbeing in South Africa

Aside from the very high inequality of land ownership, South Africa is characterised by a dual land tenure system comprising of private ownership and communal land ownership. Using waves 4 and 5 of the National Income Dynamics Study longitudinal data set, a set of econometric methodologies is employed to quantify the impact of ownership and tenure on an index of subjective wellbeing (SWB) constructed from eight self-reported responses covering general life satisfaction, contrast, social capital, mental health and hope for future. Controlling for the income effect and other pertinent drivers of SWB, the study highlights the non-income impact of land ownership and tenure on the subjective wellbeing of individuals. To account for possible endogeneity and self-selection, instrumental variable and matching method-based treatment effects are computed. This paper has two main findings in relation to land tenure in South Africa: (a) land owners have on average a higher index of SWB compared to those not owning land, and (b) owning land privately, compared to owning land communally, has a positive impact on subjective wellbeing within land owners. These results are consistent and statistically significant across the various estimation strategies and provide additional motivation for expediting land reforms in South Africa.

Demand for second-stage land certification in Ethiopia: Evidence from household panel data

Ethiopia has implemented one of the largest, fastest and least expensive land registration and certification reforms in Africa. While there is evidence that this ‘first-stage’ land registration has had positive effects in terms of increased investment, land productivity and land rental market activities, the government is now piloting another round of land registration and certification that involves technically advanced land survey methods and computer registration. This ‘second-stage’ land registration differs from the registration system employed in the first round that used field markings in conjunction with neighbors’ recollections to identify plot borders. We use panel data from 600 households in southern Ethiopia to investigate household perceptions of and demand for such a new registration and certification. Our study revealed relatively low demand and willingness-to-pay (WTP) for second-stage certificates. The WTP also decreases significantly from 2007 to 2012. Our findings indicate that farmers do not believe that the second-stage certificate enhances tenure security relative to the first-stage certificate except in instances in which first-stage certification was poorly implemented. The demand for second-stage certificates appears to come primarily from governmental authorities, as it can provide a better basis for land administration and produce accessible public documentation of land-related affairs.
