The land grabbing in the international scenario: the role of the EU in land grabbing

The worldwide increase in population and consumption has produced a growing demand for food and energy in the rich and developing Countries. The resulting intensification of land investments, to cope with this need, has in many cases produced investments without transparency rules and it hasn’t created real development for local people. The aim of this paper is to identify, through a cluster analysis, homogeneous groups of investor Countries in order to understand the role of the EU Member States in the context of land grabbing. The results show that the strategies adopted by the investors are driven by the need to achieve energy security and reduce CO2 emissions in order to cope with the problems of food security and to adopt the proposals and the objectives of the European Union Policy for Sustainability. In particular, the acquisitions of EU Member States are driven by the need to provide enough food for the exponential growth of the population and to reduce the energy deficit in view of the achievement of the objectives set out in the “Europe 2020”.


Background
The land grabbing phenomenon has prompted a lively and wide-ranging scientific debate about its alarming spread and the implications for economic, political, ethical, and social issues. The term "land grabbing" indeed, describes large-scale and long-term farmland acquisition below the real market values, and it is also strongly correlated with the political, social, economic and environmental aspects of nations and people in the world.
The land grabbing covers several European Union (EU) Member States, not only as investors but also, more recently, as recipients. Regarding EU investor Countries, the relationship between land grabbing and European policies for agriculture and environment is very close. Every action and commitment made by the EU in policies to reduce carbon dioxide (CO 2 ) emissions in the fight against climate change and in food and energy policies have a common denominator: soil resources (European Commission 2008, 2010aUnited Nations 1992a, b, 1998. The achievement of international goals for decarbonisation has pushed for the use of renewable energy and biofuels but the Agricultural and Food Economics context has created a lively discussion on the intended use of the land. Today, biofuels are among the stronger competitors in the usage of arable areas for foods (European Commission 2006, 2010aFAO 2013). With this in mind, the aim of this study is to identify homogeneous groups of investor Countries, among 57 world countries. The sample was selected based on available data, taking into account transnational investments only and ignoring domestic land acquisition. This classification allows us to assess the role of EU Member States in the international land-grabbing scenario.

Literature review
According with the Tirana Declaration land is "grabbed" when land deals occur under one or more of the following points: "(i) in violation of human rights, particularly the equal rights of women; (ii) not based on free, prior and informed consent of the affected land-users; (iii) not based on a thorough assessment, or are in disregard of social, economic and environmental impacts, including the way they are gendered; (iv) not based on transparent contracts that specify clear and binding commitments about activities, employment and benefits sharing, and; (v) not based on effective democratic planning, independent oversight and meaningful participation" (International Land Coalition 2011, p. 2).
The phenomenon stems largely from world population growth, today approximately 7 billion and estimated to be 9 billion in 2050 (FAO 2013), with consequent need of food and energy consumption (including renewable energy) and growth of insecurity. This is true, in particular, in many African countries where in the last few years was registered a growing food insecurity in cereals due to rapid increase of population and urbanisation process (Galati et al. 2014). In the last few decades, the need to achieve food and energy security has been among the reasons that pushed governments and multinational corporations to search for land in which to invest. Other reasons are: the need to exert more control on the global market, especially for scarce resources such as water and soil; ensure economic viability and social stability of their own governments; expand and diversify company and investment funds (Buxton et al. 2012;Deininger andByerlee 2011). However, according to De Castro (2011) the problem of the 'new scarcity' of food cannot be explained only by analyzing the demographics and production, but rather looking at the unequal distribution of basic resources such as land, livelihoods and 'know-how'. Land grabbing takes place mainly in underdeveloped and developing countries that are, thus, exploited and become further impoverished and robbed of not only of their environment but also of human capital. As asserted by Zagema (2011), the populations of the areas affected by land grabbing are frequently forced into exile without being able to claim the right of ownership of their land. In general, the contracts provide acquisitions or leases of vast fertile areas for periods between 25 and 99 years, with rents that can range from €0.60 to €16 per hectare and per year (Liberti 2011). On the other hand, the recipient governments consent is mainly due to opportunities to benefit from transnational capital to start processes of growth and modernization through the creation of jobs, the production of cash crops and the construction of infrastructure (Cotula et al. 2009;Lavers 2012). As suggested by Longhitano (2010) the negotiations exploit the particularly favourable conditions of the land market in developing countries, on account of the lack of certainty regarding property rights, and appeal to local governments for potential returns in terms of infrastructure and increase in GDP and employment rates.
According to the Land Matrix Global Observatory, 1 the area covered by large-scale investments entered into by foreign investors is almost 35 million hectares (The Land Matrix Global Observatory 2014). All continents are involved, the largest share of acquired land is concentred in the Sub-Saharan Africa (Deininger and Byerlee 2011).
The World Bank maintains that the increasing global interest in agriculture is a serious threat to small farmers in developing countries, because of the problems that could stem from their inability to gain access to land and natural resources. On the other hand, the World Bank also considers these 'dangerous investments' as an opportunity for development of poor countries (Deininger and Byerlee 2011).
Some authors wonder if land grabbing phenomenon is a form of neo-colonialism or if it is instead an opportunity for development of developing countries.
Da Vià (2011) argues that the land grabbing is a win-win situation, that is as a good situation for everyone involved; this is a way to legitimize a model of agricultural development characterized by neo-liberalism, which aims to promote "policies geared toward the concentration of corporate power in the food system, the expansion of 'value chains' , the commodification of land and labour, and the removal of public interventions such as price controls and subsidies to small producers".
By contrast, a model which is based on large-scale land acquisition seriously endangers the local communities. These often suffer for the higher costs of such a policy which does not take account of those who traditionally hold the land for customary law, and therefore cannot claim property rights that are legally relevant (Alden et al. 2012).
These diverse standpoints are summarised by De Schutter (2011) and Robertson and Pinstrup-Andersen (2010), who think that investments in agriculture by foreign investors are an important tool in raising the economies of poor countries, provided that populations' human rights are respected and that they are involved in the deals. This approach would allow them to decide their future and, thus, avoid the development of problems regarding food security and nutrition which are strictly connected to their ability to gain access to land.
In this debate, De Castro (2011) states that land grabbing is one of the issues that require quick and effective solutions in order to ensure food security and fundamental rights for current and future generations. He adds that we need a shared commitment by the political and civil society in the search for new models marked by solidarity, sustainability and ethical use of natural resources. These models provide for the involvement of more about 500 million small farmers in developing countries, to enhance the food security of the people and reducing social instability in these countries at the same time.

Methods
In order to identify homogeneous groups of investor Countries and the role of the EU Member States in the international scenario of land grabbing, we used the cluster analysis both to identify specific market segments, and to analyse socio-economic disparities among territories. In this first step we have identified 26 socio-economic and environmental variables related to the land grabbing phenomenon, such as the average dietary energy supply adequacy, political stability and absence of violence/terrorism, energy production, GDP per capita, etc., according to the economic literature (Von Witzke and Noleppa 2010;Franco 2011, 2012;Hall 2011;Matondi et al. 2011;Cotula 2012;Rulli et al. 2012;Scheidel and Sorman 2012;Margulis et al. 2013;McMichaela 2013). The sources used are data sets from Land Matrix, the World Bank, and the Food and Agriculture Organization (FAO 2014). Eleven variables have been excluded for the lack of data both for all the 57 investor Countries considered and for the entire 2000-2013 period. At the end of this preliminary phase, the socio-economic and environmental variables that we have used in this work are the following five: The variable Land_grab_size, from Land Matrix 1 database, expresses the surface acquired by transnational investors in foreign countries in the period 2000-2013; The variable CO 2 from World Bank data, is the amount of CO 2 emissions stemming from the burning of fossil fuels and manufacture of cement during the period 2000-2013; The variable per capita agro-forestry surface (Agr_For_Pop) expresses the available per inhabitant land to carry out activities in the agricultural and forestry sectors. The data were obtained from sources of the FAO and refer to the period 2000-2013; The variable Energy_dep is the amount of energy imported, measured as a percentage of total energy use. The data were obtained from the site of the World Bank. The reference period is from 2000 to 2013; The variable Amv_Pop expresses the average annual rate of change of population in the 2000-2050 period and was obtained from the data published by FAO.
On the basis of the described variables, we conducted the cluster analysis -using SPSS 17, to identify homogeneous groups of countries. All the variables used have been standardised, both for the purpose of this analysis and to delete existing differences among the measurement units. The cluster analyses starts with a hierarchical method which yields the suitable number of clusters and the group of centroids. In the second step, the clusters are refined further using a non-hierarchical methodthe k-meanswhich maximises the Euclidean distance between cluster centres while minimising the distance between members of any given cluster. In order to verify which is the better elaboration to classify the countries studied, different elaborations are carried out by varying the number of clusters, up until a number is identified such that additional groups contain only a few countries with significant short distances. Previously, an analysis of the correlation coefficients was performed in order to eliminate redundant variables (e.g. the food dependency index). Furthermore, in order to make the comparison across all variables simultaneously and to track the ranking of the groups, we have considered the standardised average values from the variance matrix, to overcome the constraint linked to the different units of measurement without losing the variation between the values.

Results
As we can see in Tables 1 and 2 and in Fig. 1, there is a significant concentration of EU Member States (14 of 17 investors) in the first cluster. This cluster includes 42 countries with lower average values than the other clusters for surfaces acquired, CO 2 emissions and rate of population growth. On the contrary, these countries show high energy dependency and low agricultural and forestry area per capita. As suggested by Scheidel and Sorman (2012), the energy security threats are the drivers to acquire land for the expansion of energy systems, especially in the presence of low availability of arable land.
This result helps to explain the common behaviour of many investors of the EU Member States area, which are almost entirely characterised by energy deficits and have committed to achieve the European objectives of utilizing at least the 20 % of renewable energy before 2020. However, inside this group, there are some countries that are self-sufficient in terms of energy and that are, in fact, energy exporters; these countries, despite their high rates of population growth, have acquired limited foreign areas.
The second cluster comprises seven countries (including three EU Member States) with the highest acquired surfaces and high energy dependence compared to the first cluster. They are also inclined to higher average values of CO 2 emissions. In addition, this group includes many countries that have limited availability of land per capita, which is one of the key factors behind pushes to acquire arable land. Spieldoch and Murphy (2009) emphasise that countries plagued by natural resource constraints (e.g. deficiencies in arable land) are the major exploiters of natural resources abroad. The acquisition of arable land, mainly in the Global South, aims to establish tree plantations wholly or partly for biomass energy for export or for domestic markets, to reduce greenhouse gas emissions (Cotula 2011(Cotula , 2012 and, as in the case of India and Korea, to produce food for their growing populations (Hall 2011).
The Cluster 3 contains three countries characterised mainly by high rates of population growth compared to the average of the groups. Among these United Arab Emirates show a high level of acquisition. The link between demand for land and population growth, mainly in high-and middle-income countries, has been emphasised by different authors (i.e., Cotula et al. 2009;Robertson and Pinstrup-Andersen 2010). In  fact, the increase of population has stoked an increasing pressure on land use for subsistence, potentially depriving the poor populations of their ability to support themselves (Cotula et al. 2009). These countries probably invest for a future perspective of food insecurity, which has prompted corporate investment in food crops and in energy security (Godfray et al. 2010;White et al. 2012). Finally, in the Cluster 4, there are five countries that are self-sufficient in terms of energy but that, in contrast, exhibit high CO 2 emissions, which is one of the main motivations behind the acquisition of productive land in foreign countries. This group has many countries with the greatest obligations to reduce emissions, according with the Annex B of the Kyoto Protocol (United Nations 1998). As asserted by Peters et al. (2011), these countries have shifted an increasing proportion of their CO 2 emissions to countries without emissions ceilings.
The analysis of the differences between the F-ratios makes it possible to draw general conclusions about the role of the different mean variables in the forming of the clusters. The results show that the average annual rate of change of population and investment size have great influence on the formation of the cluster, followed by the per capita agro-forestry surface and then by the CO 2 emission and energy dependence variables.

Discussion and conclusions
The main aim of this work was to identify the drivers of the choices of the investor Countries and assess whether EU Member States assume common behaviour in land grabbing scenario. The results showed that is possible to identify homogeneous groups of countries according to socio-economic and environmental variables observed. In particular, the EU Member Countries (Cluster 1) are characterized by the need to reduce the energy deficit and the CO 2 emissions to achieve the 'Europe 2020 Strategy' , although, as our findings suggest, they are characterized by a lower levels of CO 2 emissions compared to other countries. This can be explained by the increasing interest for European Union policies to safeguard the environment and combat climate change. In fact, the EU as part of the 'Europe 2020 Strategy', decided unilaterally to achieve specific goals by 2020 as the reduction of CO 2 emissions by 20 % compared to 1990 and to obtain 20 % of energy needs from sources of renewable energy (European Commission 2010a, b). These facts have led and developed the EU policy on bio fuels, creating a market and building the foundation for the development of agro-industrial bio fuels in the EU and in developing countries (Franco et al. 2010). This approach, at least in appearances, bases its foundations on three essential elements that are greater energy security, reduction of greenhouse gases and rural development in developing countries (Borras and Franco 2011;Franco et al. 2010;Aubry 2012). As mentioned by Aubry (2012), the EU policy on bio fuels is an important driver of land grabbing in Africa as evidence the increase in demand for land to produce bio fuels and export them to the European Countries. If you add to this the increase in palm oil investments in some of the Southeast Asia regions since the adoption in 2008 in the European Parliament's mandatory quota of 10 % of green fuel in the transport sector (Pye 2010), we can easily deduce the strong link between land grabbing and European policies. Crops such as maize, oil palm or cane sugar for bio fuel production need, in fact, of large tracts of land that are the basis for the development of phenomena related to land grabbing (Aubry 2012); Aubry argues that the positive impact provided by the Renewable Energy Directive, in fact, gives assurances only on environmental sustainability criteria and does not prevent the negative social impacts with the grave danger of opening the doors to possible cases of land grabbing.
In general, the four groups of countries identified highlight that the strategies adopted by the investors are driven by the need to achieve energy security and reduce CO 2 emissions (Clusters 1, 2, and 4) and to resolve food security problems (Cluster 3) linked to exponential population growth. A central role in this complex phenomenon is played by the international agricultural and environmental policies (particularly those related to climate change and to strategic programs for energy).
The research results were affected by the variables considered, whose choice was dictated by the need to have complete data for all the investor Countries and for all the studied period (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013). Nevertheless, the results offer a contribution to the research on land grabbing. Up to now, studies about this phenomenon were focused on recipient Countries, overlooking the role of investors. However, a greater detail regarding to the size of the investment type in agriculture, forestry or energy (data not available in international databases) could allow the study to give a bigger acknowledgment and explanations of the specificity within individual clusters identified.
