Effect of farmland scale on agricultural green production technology adoption: Evidence from rice farmers in Jiangsu Province, China

Agricultural green production technology (AGPT) is crucial for mitigating farmland pollution and degradation, as well as promoting green agricultural development. Using data from 774 rice farmers in the 2021 China Land Economy Survey (CLES), the study analyzes the impact mechanisms and mediating pathways of farmland scale on AGPT adoption at both the farmer and plot levels. The study also reveals the differences in impact based on the heterogeneity of plot concentrations and technological attributes. The results show that: (1) Farmland scale positively impacts AGPT adoption, both at the farmer and plot level. (2) Farmland scale positively impacts AGPT adoption at two levels by affecting commercialization rate, time preference, and machinery investment. (3) The positive impact of farmland scale are heterogenous at two levels. When rice is scatteringly planted, plot scale has a more significant impact on AGPT adoption than operation scale; however, when rice is concentratedly planted, the situation is the opposite. Additionally, when faced with "capital-increasing, labor-saving, and risks-increasing" technology, operation scale has a more significant impact on AGPT adoption than plot scale; however, when faced with "capital-stabilizing, labor-increasing, and risks-controlling" technologies, the situation is the opposite. These findings help to provide policy implications for promoting AGPT adoption and sustainable farmland use.

Flammable futures—storylines of climatic impacts on wildfire events and palm oil plantations in Indonesia

Abstract Wildfire events are driven by complex interactions of climate and anthropogenic interventions. Predictions of future wildfire events, their extremity, and their impact on the environment and economy must consider the interactions between these drivers. Economic policy and land use decisions influence the susceptibility of an area to climate extremes, the probability of burning, and future decision making. To better understand how climate-driven drought events and adaptation efforts affect burned area, agricultural production losses, and land use decisions, we developed a storyline approach centered on Indonesia’s 2015 fire events, which saw significant (>5%) production losses of palm oil. We explored analogous events under three warming conditions and two storylines (multi-model ensemble mean climate change and high impact). We employed a model chain consisting of CMIP6 climate modeling to quantify climate change impacts, a wildfire climate impacts and adaptation model (FLAM) to predict burned areas, and the Global Biosphere Management Model (GLOBIOM) to predict resultant production losses and socio-economic consequences in the oil palm sector in Indonesia and, by extension, the EU. FLAM is a mechanistic fire model used to reproduce and project wildfires based on various criteria and input variables; GLOBIOM is a global economic land use model, which assesses land use competition and provides economic impacts based on scenario data. We found that total burned area and production loss can increase by up to 25% and lead to local price increases up to 70%, with only minor differences beyond 2.5 degrees of warming. Our results highlight the importance of considering the interactions of future warming, drought conditions, and extreme weather events when predicting their impacts on oil palm losses and burned area. This study sets the stage for further exploration on the impacts of land management policies on local and international environments and economies in the context of global warming.

Research on the Impact of Agricultural Production Outsourcing on Farmers’ Fertilizer Application Intensity: An Inverse U-Shaped Relationship

Agricultural production outsourcing services encourage a shift in the way crops are grown in developing countries and make it easier for small farmers to join the social division of labor in agriculture. This makes production more efficient and has a big effect on the inputs used in agriculture, especially fertilizer. This paper empirically tests the impact of production outsourcing on farmers’ fertilizer intensity using the instrumental variables method with non-planar panel data from the 2020–2022 China Land Economy Survey (CLES) of farm plots. The results showed that there was a significant inverted U-shaped relationship between the degree of agricultural production outsourcing and the intensity of fertilization on farmers’ plots. Mechanistic analysis shows that agricultural production outsourcing affects the fertilizer intensity by changing the labor allocation of farmers. Especially as the degree of agricultural production outsourcing increases, the intensity of farm labor inputs by farmers gradually decreases, and the impact of fertilizer intensity on the plots showed a tendency to be promoted first and then suppressed. The moderating effect showed that plot size was a major moderating factor. This means that the bigger the plot, the flatter the inverted U-shaped curve became, and the same level of outsourcing could lead to less fertilizer application. This happened by moving the inflection point of the inverted U-shaped curve to the left, which stopped the fertilizer application at a lower level of outsourcing. Heterogeneity analysis showed that participation in technology-intensive production outsourcing was beneficial in terms of reducing fertilizer intensity, and that an increased degree of agriculture production outsourcing was beneficial for farmers with large plot sizes and younger heads of household.

The Political Economy of Land Reparations in South Africa

ABSTRACTThis article examines white settler colonialism and racial capitalism as the primary mechanisms for the historical and ongoing land dispossession of Afrikan people in South Africa. It argues that by addressing land dispossession through land restitution, South Africa could begin to meaningfully address the ongoing impacts of settler colonial displacement of Afrikan people. It contends that land reparations are central not only to restorative physical and spatial justice but also to physical healing. The aim of this contribution is to historicize and herstoricize the South African land question; situate this within the context of racial capitalism and settler colonialism; provide a framing of the racialization and feminization of the land economy; and expound on the particularities of misogynoir and critical feminist theory in theorizing the acute land dispossession of Afrikan women. Situated within the Azanian School of thought, its essential contribution is the suggestion that land restoration is a necessary and meaningful reparative measure for South Africans.

Provincializing western planning concepts in a Chinese City: the intertwined adaptation of introduced ideas and local agents in shaping the Guangzhou Central Business District

ABSTRACT The adoption of Western planning ideas has significantly shaped China’s Central Business Districts (CBDs) and spurred economic growth. This article goes beyond existing research by exploring the “provincialization” of Western planning concepts, resulting in unique CBD landscapes in Chinese cities. Through a study of the Guangzhou CBD, it reveals how introduced ideas and local agents mutually adjust and respond to each other’s needs during the provincialization process. Under the “Reforms and Opening-up” policy, Chinese authorities drew from Hong Kong’s experiences to introduce the CBD concept, adapting it to underdeveloped land in Guangzhou and blending it with American downtown design. To meet urban space demands, industrial growth, and land economy needs, urban authorities reorganized local resources to create a discourse of the “central axis” to integrate the CBD concept into the urban layout. Consequently, both introduced ideas and local agents are intertwined to address challenges posed by each other, resulting in Guangzhou’s CBD framing a hybrid urban landscape.

Rediscovering the location of agricultural production: Spatial linkage of farmland use intensity and labor opportunity costs in Central China

Agricultural location theory was the earliest work to reveal the land use and agricultural layout of urban suburbs; however, there is an increasing difference between Dunn's theoretical model and modern agricultural layouts, and there is thus an urgent need to establish new theoretical relationships. In this work, we sought to reveal new patterns of modern suburban agricultural land use using remote sensing data and land economics knowledge. We used remote sensing data to obtain first-hand land-use information while considering the attractiveness of the urban center to labor, and we explored the impact of agricultural opportunity costs on agricultural land use. We found that agricultural land use in suburbs in Central China have four obvious layers: dominance of built-up areas, dominance of single cropping, dominance of double cropping, and dominance of triple cropping. From the perspective of planting patterns, with increasing distance from the city center, the proportion of single-cropping areas decreases from 60% to 20%, that of double-cropping areas increases from 20% to 70%, that of triple-cropping areas always remains below 10%, and the multiple-cropping index increases from 120% to 180%. From the perspective of land economics and considering labor cost, planting profits decrease with increasing distance from the city center. The increasing attractiveness of the urban center to migrant workers significantly weakens farmers' willingness to plant. From the perspective of the circle structure, before 2000, farmers' planting profits were higher than the opportunity costs in all regions; after 2000, farmers with arable land within a 40-km radius of the center may have been more inclined to choose farming, while those with land outside this 40-km radius may have been more inclined to work elsewhere. Under changing agricultural policies, farmers' planting profits increased to a historical high, but profits became negative in all regions after 2015, and the willingness of people to farm reached a historical low. With this work, we continue the development of the hierarchical structure model of The Location of Agricultural Production and summarize new laws of modern agricultural land use from the perspectives of remote sensing data and land economics, supplementing and enriching agricultural location theory.

Value switching: Extracting profit from the city

Land and property, and the wealth extracted from it, has reappeared as a central concern in understanding the process of urbanisation under capitalism. Much of the academic discussion centres on the re-emergence of ‘rentier capitalism’ drawing on 19th-century concepts of land economics. However, the accumulation of wealth through property ownership and the development process points towards a value proposition contained in the land question that is not satisfactorily explained by notions of ‘rent’ or ‘rentier’ capitalism, rooted as they are on 19th-century concepts of the land development process. This article seeks to extend this debate by exploring multiple regimes of value that underpin the contemporary urban development process. The first part of the article maps out four intersecting regimes of land value, before arguing by reference to empirical analysis of land and property sales data in Sydney Australia that switching between these value regimes – value switching – is a key transformative moment in the urban development process. Specifically, this article argues that value switching, as triggered by the land use planning process, has become the key driver of urban development dynamics and adds a further dimension to theories on land and housing development in the financialised city.

A study of the driving factors of the intention and behavioral deviations of rural residents in waste classification

Introduction: The deviation between the stated intentions and actual actions of rural residents regarding waste classification constitutes a significant impediment to the effective implementation of environmental management strategies in rural areas. It is therefore recommended that steps be taken to reduce the deviation between the stated intentions and actual behaviors of rural residents. Doing so will help to reinforce environmental governance in rural communities and provide the necessary support for rural revitalization.Methods: This study establishes an analytical framework for examining the deviation between the internal perceived efficacy and external environmental policies among rural residents. The relationship between intention and behavior can be classified into three distinct scenarios: “intention with behavior,” “intention without behavior,” and “no intention with behavior.” Furthermore, an empirical analysis is conducted using survey data collected by Nanjing Agricultural University in the China Land Economic Survey in June and July 2021.Result: The results show that 1) the perceived efficacy has a significant positive influence on the deviation between the intention and behavior of rural residents in domestic waste classification, while the environmental policy has a significant negative effect on it; 2) the guiding policy has a significant negative moderating effect on the influence of perceived efficacy on the deviation between the intention and behavior of rural residents and the situation of “with intention and without behavior,” while the reward–punishment policy has a significant positive moderating effect on the influence of perceived efficacy on “without intention and behavior;” 3) the perceived efficacy has a masking effect on the impact of environmental policies on the deviation between the intention and behavior or “with intention and without behavior” of rural residents and a partial mediating effect on the impact of the environmental policy on “with intention and behavior” or “without intention and behavior.”Discussion: In consideration of these findings, the study proposes policy recommendations that emphasize the interconnectivity of the government, village collective organizations, and rural residents. The recommendations include the implementation of environmental policies and initiatives designed to enhance rural residents’ awareness of waste classification.

Fire is associated with forest degradation and economic land concessions, but not land conversion in the rapidly transforming Cambodian landscape

Abstract Cambodia is beset by high deforestation rates and fire frequencies. From 2001–2020, forest cover declined by 34%, and cropland and rubber expanded by 31,401 km2 and 4,530 km2, respectively; meanwhile nearly 8.7 million fires burned 41.6% of the land. Fires may be associated with deliberate land change, stable land management systems, and unplanned forest degradation. We integrated annual land cover and monthly burned area data from 2001–2020 to test three hypotheses. First, if fire is used during land conversion, there would be a detectable pulse in fire activity in the year immediately prior to, and the year of land cover change. Our temporal analysis found statistically elevated burn rates in five of 16 transition tests, however, they were typically <1% outside the predicted range, indicating no practical significance in the association of fire with land cover change. Second, fire prevalence would be lower in land managed for conservation or agricultural production than unclassified or unmanaged land. persistent forest and shrubland burned at significantly higher rates than expected, cropland burned significantly less, burning was almost absent from rubber plantations, and forests in protected areas (PAs) exhibited lower total burn percentages than unclassified land or industrial economic land concessions (ELCs), thus supporting the fire-land management hypothesis. However, total burned area in ELCs was greater than unclassified land for several persistent land cover classes, suggesting that local landowners may prevent fire in commercially valuable private agricultural land, but there may be no such prevention measures in industrial ELCs. Anti-fire policy enforcement in ELCs should be enhanced. Third, forests that converted into (degraded) shrublands would experience increasing fire frequency in the years leading up to transition, a hypothesis we found strong support for through our temporal analysis. Cambodia’s 2013 Law on Fire Prevention and Fire Fighting deputizes the public to enforce its provision, however given that the vast majority of fires occur in persistent forest in state-owned land, collective action problems are likely to hinder its effective implementation.

Reducing the negative impact of wildfire disasters through multi-scenario risk analysis of land investment

Natural meteorological and climatological hazards and vulnerable vegetation are frequent triggers of natural disasters, such as wildfires. These cause loss of life and significant economic damage, likely to increase due to climate and socio-economic changes. The increase in wildfires in recent decades has affected the decision-making of technocrats and policy experts and created the need for more sophisticated risk management. This paper develops a theoretical framework for reducing the economic impact of wildfire risk on forests. Also provides insight into land use decisions regarding losses that this increased risk of forest land management can cause. The impact of wildfire risk on economic land value is evaluated by comparing three scenarios, i.e. the deterministic risk-adjusted land expectation value with its risk-free counterparts calculated assuming the stationary risk and predicted increasing risk as time goes by. Also, for this purpose, we evaluate the economically optimal length rotation period pine stands and the risk premium. Fire risk is described as the probability of pine stands destruction due to their age and meteorological conditions in the experimental area Záhorská lowland (western Slovakia). Our findings highlight the importance of alerting forest policymakers to carefully incorporate assessment of the increasing risk of random natural disasters due to climate change into sustainable forest management. The study's results will also help current or future forest owners estimate and evaluate the economic/investing risk when buying or selling forest land.

The impact of digital literacy on farmers' pro-environmental behavior: an analysis with the Theory of Planned Behavior

IntroductionThe rapid development of agriculture has brought about significant negative impacts on the environment, such as land pollution and ecological degradation. The root cause of environmental issues lies in human behavior, with improper farming practices by farmers being a major contributor to agricultural pollution. This paper explores the relationship between farmers' digital literacy and their pro-environmental behaviors, examining the mediating roles of subjective norms, behavioral attitudes, and perceived behavioral control. Additionally, it investigates the varying impacts of digital literacy on PEB among farmers with different levels of education, social capital, and household income.MethodsBased on data from the China Land Economic Survey (CLES), this study utilizes an ordered probit regression analysis method to analyze data from 923 sample respondents in 24 villages in Jiangsu Province. All analyses were conducted using Stata 15.0.ResultsThe research findings indicate that digital literacy enhances the likelihood of farmers engaging in PEB. This practice is achieved by reinforcing farmers' subjective norms, strengthening their behavioral attitudes, and enhancing their perceived behavioral control (as the core elements in the Theory of Planned Behavior theory), thereby promoting the implementation of PEB among farmers. Further analysis reveals that digital literacy plays a crucial role in enhancing PEB among farmers with higher levels of education, social capital, and household income.DiscussionThe results of this study suggest that policymakers should enhance farmers' digital literacy and implement specific measures to improve farmers' subjective norms, behavioral attitudes, and perceived behavioral control. When the digital literacy and willingness for PEB are improved, farmers may engage in environmentally friendly practices.

Can Non-farm Employment Improve Dietary Diversity of Left-Behind Family Members in Rural China?

Rural residents in China are still at risk of malnutrition, and increasing dietary diversity is crucial to improving their health. This study empirically analyzed the impact of non-farm employment on the dietary diversity of rural left-behind family members based on the China Land Economy Survey (CLES) 2020-2021 panel data at the farm and village levels. Dietary diversity was measured using the dietary diversity score (DDS) and the Chinese Food Guide Pagoda Score (CFGPS). The empirical results show that non-farm employment significantly enhances the dietary diversity of rural left-behind household members, including animal food diversity and plant food diversity. This result verifies the altruism phenomenon of non-farm employment in family diet. Mechanism analysis shows that non-farm employment enhances the dietary diversity of rural left-behind family members by increasing the level of family income, Internet accessibility, and family education. Heterogeneity analysis shows that non-farm employment does not enhance the dietary diversity of rural empty nesters and even has a negative impact. This reminds us that the nutritional health of rural empty nesters needs attention in the context of rapid urbanization and aging.

Centennium of collegiate real estate education: a prospection on “the search for a discipline” in the American school of business

PurposeThis study reviews the teaching of real estate in the USA for the first 100 years after the foundational curriculum was laid down in 1923 by three key institutions: the National Association of Real Estate Boards (NAREB), the Institute for Research in Land Economics and Public Utilities (The Institute) and the American Assembly of Collegiate Schools of Business (AACSB). Its line of investigative pursuit is the persistent lamentation by American real estate scholars that real estate is not getting the respect it deserves as an academic discipline compared to its peers in the school of business such as accounting, finance and marketing. The study addresses a fundamental question: What is the cause of this endless “search for a discipline”? This is motivated by the belief that identification of the root cause of this “search for a discipline” will lead to the requisite solution: the intellectual foundation of the real estate discipline.Design/methodology/approachThe study used qualitative document analysis to review two primary documents published in 1959 as reports on business education in the USA: (1) Higher Education for Business, financed and sponsored by the Ford Foundation, and (2) The Education of American Businessmen – financed and sponsored by the Carnegie Corporation of New York. The impacts of the publications on the teaching of real estate to date have been reviewed in the context of scholarly actions and literature that has been generated in relation to the two documents.FindingsThe two primary documents impacted negatively on the teaching of real estate. The committee members who produced the two reports had indicated that real estate did not fit into the business curriculum hence should not be taught in business school. This conclusion led to unintended negative outcomes for real estate education. The negative impact of the reports arose principally because the teachers of real estate misinterpreted the outcome to mean that they should tweak the real estate curriculum to fit in the pedagogical framework of the business school. This reaction is responsible for perpetuating the identity crisis that has plagued real estate as an academic discipline since its inception as a subject of study in 1923. Secondly, at the inception of the real estate education in 1923, while the AACSB accepted real estate as a discipline in the school of business, Richard T. Ely wrote the curriculum under land economics which has led to the persistent collegiate dilemma regarding the teaching of the discipline.Social implicationsThe study sheds light on the situation of business education in the USA and AACSB-accredited colleges internationally. It draws attention to the incoherent body of knowledge of business education and will help schools of business to redesign their curricula to include course contents that rightly reflects the business oriented academic disciplines.Originality/valueThe study is timely as it has been done 100 years since the development of the first standard collegiate real estate curriculum following the 1923 conference at Madison. The study has reviewed the first 100 years in terms of the persistent quest: “in search of a discipline”. In so doing, it has uncovered the root cause of this search during the first centennium; and to end the search, it proposes that real estate should not be taught as a business discipline.

Can markets for nature conservation be successful? An integrated assessment of a product label for biodiversity practices in Germany

Biodiversity is declining in many ecosystems, particularly in agricultural landscapes. So far, instruments such as the Common Agricultural Policy (CAP) have not been able to halt this trend. Stricter legal regulations tend to be poorly received by farmers and this leads to conflicts. However, their acceptance is crucial as agriculture is a major stakeholder in biodiversity conservation. In this context, market-based approaches are alternative or complementary instruments for biodiversity conservation. However, there are few examples in Germany and the potential economic feasibility on a larger scale has hardly been investigated. We, therefore, analyzed the economic and agronomic impacts of a potential new market label for biodiversity-friendly products on conventional arable farms in two German case study regions – Brandenburg and North Rhine-Westphalia (NRW) – with different agricultural frameworks. The label requirements were defined in advance by a group of experts in the field of nature conservation. In terms of methodology, we combined a survey of nine companies in the food sector, for instance food retailers, that looked at potential price premium scenarios for products with the label and economic land use modelling. The participation of farms led to an average reduction of gross margins per hectare of arable land of approximately 64 € in Brandenburg and about 96 € in NRW. This revealed spatial disparities. Regarding biodiversity impacts, pesticide use was reduced by about 50 % in both regions. This indicated a high level of effectiveness coupled with comparably moderate farm adaptation costs. Price premiums under the market label for potatoes, wheat, and rye averaging 10 % could almost compensate for the loss of farm income in both regions. Premiums between 5 % and 10 % were also the order of magnitude estimated by the companies that took part in the survey. At the same time, the survey did show that potential transaction costs could be quite high. We, therefore, concluded that the market alone was unlikely to finance the introduction of the label in the case study regions. There was a need for accompanying instruments such as the CAP or private business investment. However, given the case study character, the results should be interpreted with caution and cannot be considered representative of all German or European agricultural conditions. They require further research. Nevertheless, our results are highly relevant for policy makers, as they show that biodiversity conservation, at least in the study regions considered, cannot be tackled with one single instrument, but requires a mix of different ones. For instance, a combination of policies and private initiatives, such as the CAP and a private market label like the one considered in the study.

‘One System, Two Shadows’: A local public finance perspective on China's shadow banking system

Why does shadow banking persist in China despite repeated policy efforts to contain it? While studies of informal finance have traditionally emphasized the credit needs of private businesses as a demand-side explanation, this study contends that China's local public finance also constitutes an important driver for shadow banking. Based on document research and administrative data, we find that China's shadow banking system has bifurcated into two segments since the Global Financial Crisis (GFC). One is the ‘entrepreneurial shadow’ that has long provided informal credit to the private sector, especially small- and medium-sized enterprises. The other is a ‘fiscal shadow’, which serves property developers and local government financing vehicles (LGFVs), the two pillars of China's land-based local public finance regime. Property developers are major contributors to local fiscal revenues through the land economy, while LGFVs function as off-balance sheet backdoor financing intermediaries for local governments.Although localities have borrowed from unconventional sources throughout the reform era, the central government's GFC stimulus plan marked a turning point by fueling a debt-financed real estate and infrastructure construction boom. Property developers and LGFVs were launched onto a highly leveraged model of feverish expansion for over a decade. When the central government abruptly reversed its course by restricting the availability of formal credit, they became further entangled into the fiscal shadow for refinancing. Local public finance has thus become reliant on shadow banking, despite subsequent policy efforts to curb such activity. Our findings suggest the need for a more integrated analytic and regulatory framework that recognizes the mutual dependence between shadow banking and local debt – two major sources of systemic financial risks in China.

The Role of Digital Inclusive Finance in Weakening Real Estate Market Speculation

A multitude of studies have extensively examined strategies for achieving sustainable development in the real estate market. As the pivotal component of land economy, the real estate market plays a crucial role in ensuring its sound operation. However, it is currently undergoing significant adjustments and grappling with rampant speculative activities, resulting in an alarming bubble. By scrutinizing the speculative motivations of different entities, we present a novel perspective on mitigating speculation. Our analysis reveals that digital inclusive finance effectively curbs residents’ and enterprises’ speculative behavior, as evidenced by diminished prevention motivation and investment substitution motivation. Utilizing data from 280 cities, this study measures real estate market speculation by establishing a model that the volatility of the housing market turnover, as a proportion of GDP, deviates from the actual housing demand transactions based on economic fundamentals. Furthermore, it investigates the relationship between digital inclusive finance and real estate market speculation, along with its spatial effects. The findings indicate that digital inclusive finance significantly curbs real estate market speculation and has a negative spatial spillover effect. This research provides a novel model and perspective for exploring real estate market speculation while positively impacting sustainable development within the real estate market.

Resource Use Efficiency and Economics of Summer Greengram as Influenced by Land Configuration and Irrigation Regimes in North-western Part of India

Background: Pulses form a crucial protein component of the human diet and among the pulses, greengram is third most important pulse crop in India. Water is a critical input for sustained crop production and is becoming limited day by day. Hence, the need of the hour is to evaluate effective resource conservation practices, such as land configurations and scientific scheduling of irrigation to achieve higher productivity, profitability and resource use efficiency. The aim of the study was to identify most resource efficient and economical land configuration, irrigation regimes for summer greengram under sandy loam soils of northwestern India. Methods: The experiment was conducted during the summer of 2022 on Student’s farm, School of Agriculture, Lovely Professional University, Phagwara, Punjab to investigate the performance of summer greengram as influenced by land configuration and irrigation regimes. The experiment was carried out in a strip plot design consisting of 12 treatment combinations and three replications. The treatment included three land configurations viz, (L1: Flatbed, L2: Ridge and furrow and L3: Broad bed furrow) and four different irrigation regimes [Irrigating at critical growth stages (I1), 0.60 IW/CPE (I2), 0.75 IW/CPE (I3) and 0.90 IW/CPE (I4)]. Result: Among three land configurations tried, L3 recorded significantly higher water productivity, NUE and net return. Similarly, I1 recorded significantly higher water productivity whereas I4 recorded significantly higher NUE and net return. Among the treatment combinations, I1L3 recorded significantly higher water productivity (0.262 kg m-3) whereas I3L3 recorded significantly higher NUE (25.16 kg seed kg nutrient-1) and net income (₹ 72,848 ha-1) as compared to other treatment combinations. Hence, I1L3 and I4L3 can be recommended to farmers for growing summer greengram under sandy loam soil conditions in water scare regions and assured irrigation situation, respectively.

Searching for the Profitability of Energy Crops: An Agroecological–Economic Land Use Suitability (AE-landUSE) Model

The current geopolitical and energy market instability calls for speeding up the EU clean energy transition to increase energy security in all the European regions and make Europe the first climate-neutral continent by 2050. Among renewable energies, modern bioenergy is a promising near-zero-emission fuel for increasing energy security in the heating, electricity and transport sectors while promoting growth and job creation, especially in rural areas. In such a context, energy crops will continue to play a key role. Since agricultural planning is a complex issue, especially when energy crops could compete with food ones, we propose an agroecological–economic land use suitability model (AE-landUSE model) to promote the sustainable use of land resources. The AE-landUSE model was developed by integrating cost–benefit analysis (CBA) and land use suitability analysis (LSA) within geographic information systems (GISs). Tested in the Basilicata region (Southern Italy), comparing two different energy crops (rapeseed and cardoon), the results show the model’s utility in identifying suitable areas for energy crops where the investments will be cost-effective. The proposed model will help decision-makers in energy-agricultural planning to increase energy security sustainably.
