Una de las características definitorias del sistema urbano contemporáneo es su desterritorialización, es decir, su adopción de un modelo de desarrollo que se da al margen del territorio concreto que lo sustenta y de los recursos biofísicos y culturales existentes en él. Dicha desterritorialización es posible gracias al uso intensivo de energía que ha permitido ampliar hasta la escala global los flujos del metabolismo urbano. De este modo se han roto las relaciones de proximidad urbano-rurales, y se ha aumentado la dependencia de recursos externos. Entre las diferentes manifestaciones de esta desterritorialización se encuentra la organización del sistema alimentario, que en la actualidad responde a un modelo globalizado, en el que la distancia entre producción y consumo ha aumentado a costa de incrementar el gasto energético en transporte y conservación de alimentos. Este distanciamento físico va acompañado también de un distanciamiento social e identario, con la hegemonía de un modelo agroindustrial que no respeta los paisajes, las prácticas agrícolas, los conocimientos tradicionales ni las variedades genéticas locales. Tanto el modelo territorial como el alimentario son altamente vulnerables ante crisis externas que pueden alterar su funcionamiento. El enfoque (bio)regionalista desde el mismo inicio de la ciudad industrial hasta nuestros días ha propuesto un modelo de ordenación territorial alternativo, adaptado a las condiciones locales y basado en la proximidad, que dotaría al sistema territorial de mayor resiliencia y sostenibilidad. Para confirmar este presupuesto y evaluar la capacidad de reterritorialización alimentaria se ha desarrollado una metodología que aborda el estudio del sistema territorial como socioecosistema complejo, en el que se distinguen componentes de tipo social, construido y biofísico, que se encuentran interrelacionados. La historia de cambios en la organización del sistema, su estado actual y su capacidad de reorganizarse en estados alternativos son las bases de dicha evaluación. Esta metodología se aplica a la Comunidad de Madrid con el fin de describir su sistema territorial desde el punto de vista del abastecimiento alimentario y evaluar su capacidad de reterritorialización. ABSTRACT Deterritorialization is one of the defining characteristics of the contemporary urban system. This means that its development model is designed ignoring the attributes of the specific region in which is located, and the biophysical and cultural resources therein. Such territorialization is possible due to the intensive energy consumption that allows expanding to a global scale the flows of urban metabolism. This way, urban-rural linkages have been broken, increasing dependency on external resources. The modern food system is among the clearest expressions of a deterritorialized model. In a globalized food system, increasing distances between production and consumption spaces are possible through energy-intensive transport and preservation activities. Physical distanciation goes hand in hand with social disconnection and loss of identity, due to a hegemonic agro-industrial model that does not respect local landscapes, agricultural practices, traditional knowledge or genetic varieties. Both the regional and the food systems are highly vulnerable to external shocks that may affect their functions. The bioregionalist approach has proposed, since the industrial city until today, an alternative model, adapted to local conditions and rooted on proximity, which provides a sustainable and resilient regional planning and management. To confirm this assumption and assess the food reterritorialisation capacity, a methodology has been developed that address the regional system as a complex social-ecosystem, in which interrelated social, built and biophysical subsystems are included. Assessment is based in the analysis of regimes shifts in the history of the system, and in the description of its current and alternative states. This methodology is applied to the administrative region of Madrid in order to describe its regional food system and assess its reterritorialization capacity.

The rural population is getting smaller as percentage of the total population in the countries. There is a constant depopulation of rural areas to urban areas. The most extreme data are in countries like USA, where the rural population is 1.5%, from which 1% of that amount is part time and only 0.5% full time. On the other side, we have countries with more than 50% rural population. Related to training, cultural development, business and specific weight in society, rural residents have no significance in their societies. As they are few, and separated across the territory they have no influence on their societies. Comparing the USA farmer with one from the EU, we see that the American one is a businessperson and the European one, in most cases is a farm worker. To reduce this gap between these different farmers, we believe that we must train the new generations of children belonging to farming Europe. They must have a common language, English; they must know other countries culture and farming systems, live and network with other young Europeans colleagues,future young farmers. It is what we have coined as AGRO-ERASMUS. A project to be placed within the EU Common Agriculture Policies. The project must be designed before its implementation. Even some previous experience should make better viability. It should make use of a network of agricultural universities in several European countries. Each university would build a "farm school" where young people would learn "English?, and visit and work in small agricultural practices with a correct use of the time. One important subject dealing with should be agribusiness. The procedure based on the ?Farm School? (F-S) experience, should start with young people from 13 years up to 18 years. Their attendance, every summer, to the F-S should be rotated between different countries besides their own. The first and second year, with young people 13/14 years old, the Farm School would last less than three weeks in an English speaking country (Ireland, UK or someone else). They should live with a local family the time they stay outside of the Farm School (F-S). This two years period must be devoted to learn and become familiar with the English language and cultural differences. The rest of the four years left, the Farm Schools will have longer duration and be placed in other countries from the network. The living way would be in multinational teams of young people where the only spoken language would be English. After six years of summer oexistence speaking English and learning new competences and skills with colleagues from other countries, we would have a great team of young and future European farmers, able to travel free and confident through the whole Europe and ready to be engaged in productive, commercial and research activities. These new young farmers may revive European agriculture and would not look any more like rural habitants, but international business-farmers, professionally speaking. In a brief survey among the assistants to the Fifth International Academic Conference titled "Alternative Income Sources in Small Agricultural Holdings of the European Union" held in Krakow (PL) in June 2015, participants from universities and countries like Poland, Hungary, Rep. Czech, Portugal, Romania, etc., expressed the necessity of addressing this problem in a new and bold way.

The aim of this Factor Markets Working Paper is to identify the driving forces that shape agricultural land structures, land market and land leasing in the Former Yugoslav Republic of Macedonia (FYROM). Institutional developments and land reforms have so far been modest in the FYROM, and have not contributed to significant changes in agricultural ownership, operational structures, or land market and land leasing arrangements. Land ownership and land use are bimodal, consisting of several small-scale family farms and a few large-scale agricultural enterprises. The small family farms own and operate land on several small parcels, which is one of the major obstacles to the modernisation of family farm production. A considerable portion of the land is uncultivated, which affects land market and land leasing values. Due to underdeveloped institutional frameworks and market institutions in support of small-scale farms, a large proportion of state-owned land is rented by agricultural enterprises.

The labour force engaged in the agricultural sector is declining over time, and one can observe the reallocation of labour from family members to hired workers. Using farm-level data, this paper analyses the on-farm labour structure in Greece and assesses the factors driving its evolution over the period 1990-2008. The impact of agricultural policies and farm characteristics is examined in a dynamic panel analysis. Family and hired labour are found to be substitutes rather than complements, while agricultural support measures appear to negatively affect demand for both family and hired labour. Decoupled payments and subsidies on crops are found to have a significant impact on both sources of labour, as well as subsidies for rural development that do not favour on-farm labour use. The paper also finds that structural labour adjustments are the result of farm characteristics, such as farm size and location. The results are robust to various estimation techniques and specifications.

A KRAFT-index: Kreatív városok – fenntartható vidék egy komplex mutatórendszer, amely a fejlődési tendenciát, hálózatosodást, a fontosabb szereplők együttműködési készségét és kapacitását, kreativitási potenciálját, valamint a szereplők szinergiáiból fakadó belső energiákat és lehetőségeiket jelzi. A város- és vidékfejlesztés sikerének zálogaként előtérbe állítja és méri az ún. „puha” tényezőket, úgymint a kreativitást, innovációs képességet, új tudás létrehozását, tudástranszfert, együttműködési készséget, bizalmat, kollektív kompetenciákat. A társadalmi, gazdasági és tudományos kapcsolatok és hálózatok sűrűsége, minősége és dinamizmusa a sikeres fejlődés és fejlesztés kulcsai: ezek ma már fontosabb tényezők, mint a fizikai távolság, az adminisztratív jogi határok vagy az ún. „kemény” indikátorok. Az index értékeli egy térség lehetőségeit arra, hogy az ott élők, dolgozók, alkotók és letelepedni kívánók életminőségét, a vállalatok minőségi munkaerő iránti igényét és a fenntarthatósági szempontokat egyaránt figyelembe véve fejlessze gazdaságát és versenyképességét. Három tulajdonságcsoportot mér: 1. kreativitiási és innovációs potenciál, az új tudás létrehozásának képessége, 2. társadalmi és kapcsolati tőke, hálózati potenciál és „összekapcsoltság”, valamint 3. fenntarthatósági potenciál. _____ The KRAFT Index: Creative Cities – Sustainable Regions is a complex indicator system to measure development tendencies, ‘networkedness’, cooperation inclination and capacity, creativity potential and possibilities arising from the synergies among actors. It highlights and gauges ‘soft’ factors, such as creativity, innovation capacity, knowledge production, knowledge transfer, willingness for cooperation, trust, and collective competences and perceives effective regional cooperation among economic and social actors as the measure of successful urban and rural development. The density, quality and dynamism of social, economic and academic networks are more important factors than physical distance, administrative legal barriers or ‘hard’ indicators. The index evaluates the potential of a region to develop its economy and competitiveness by considering the quality of life of its inhabitants, workers, producers and immigrants, the quality workforce requirements of companies and sustainability. It measures three groups of qualities: 1. creativity and innovation potential, the ability of knowledge production; 2. social and connection capital, network potential and connectedness; and 3. sustainability potential.

The new development strategies should operate mainly in the areas of energy efficiency and sustainable agriculture. Thus, the substitution of fossil fuels with biofuels, such as biodiesel, is increasingly on the agenda. The cultivation of oilseed plants for biodiesel production must take place in integrated systems that enable best environmental benefits and are more economically significant. The objectives of this study were to assess the morphological, anatomic, and physiological characteristics of safflower (Carthamus tinctorius L., promising oilseed for biodiesel production) grown in monoculture and intercropping with cowpea bean (Vigna unguiculata L. Walp.); and identify socioeconomic family farmers and verify their acceptance about safflower as an energy crop. The methodology used for the analysis of safflower growth in monoculture and intercropped with beans, were morphoanatomical and histochemical analyzes, made with samples of plants grown in the field in two cropping systems throughout the range of the life cycle of these plants. There were no changes in growth and anatomy of plants, even in the consortium, which is satisfactory to indicate the intercropping system for those crops and can be a good alternative for the family farmer, who may have safflower as a source of income without giving up planting their livelihood. To check the acceptance of safflower by farmers, interviews were made to family farmers by Canudos agrovila in Ceará-Mirim/RN. It was noticed that many of them accept the introduction of safflower as oil crop, although unaware of the species, and that, being more resistant to drought, safflower help in the stability of families who depend on the weather conditions for success their current crops. In general, it is concluded that safflower has features that allows it to be grown in consortium for biodiesel production combined with the production of food, such as cowpea, and can be used enabling better development for family farmers.

This thesis analyses the influence of qualitative and quantitative herbage production on seasonal rangelands, and of herd and pasture use strategies on feed intake, body mass development and reproductive performance of sheep and goats in the Altai mountain region of Bulgan county (soum) in Khovd province (aimag). This westernmost county of Mongolia is characterized by a very poor road network and thus very difficult access to regional and national markets. The thesis explores in this localized context the current rural development, the economic settings and political measures that affect the traditional extensive livestock husbandry system and its importance for rural livelihoods. Livestock management practices still follow the traditional transhumant mode, fully relying on natural pasture. This renders animal feeding very vulnerable to the highly variable climatic conditions which is one of many reasons for gradually declining quantity and quality of pasture vegetation. Small ruminants, and especially goats, are the main important species securing economic viability of their owners’ livelihood, and they are well adapted to the harsh continental climate and the present low input management practices. It is likely that small ruminants will keep their vital role for the rural community in the future, since the weak local infrastructure and slow market developments currently do not allow many income diversification options. Since the profitability of a single animal is low, animal numbers tend to increase, whereas herd management does not change. Possibilities to improve the current livestock management and thus herders’ livelihoods in an environmentally, economically and socially sustainable manner are simulated through bio-economic modelling and the implications are discussed at the regional and national scale. To increase the welfare of the local population, a substantial infrastructural and market development is needed, which needs to be accompanied by suitable pasture management schemes and policies

This PhD thesis focuses on current livelihoods of agro-pastoral livestock keepers, their animal nutrition, herd and rangeland management strategies. It thereby aims to contribute to sustainable rangeland management, livestock production and household income in Qinghe county of the Chinese Altay Mountain region, located in Xinjiang Uyghur Autonomous Region, PR China. In its first part the study characterizes the socio-economic situation and agricultural practices of agro-pastoralists through structured household interviews. The second part provides insights into the grazing behaviour and feed intake of small ruminants on seasonal pastures in this region, and into the quantitative and qualitative biomass offer on natural rangelands. The third part analyses the reproductive performance and annual growth of the local sheep and goat herds, and, by modelling improved feeding and culling strategies, tests herd management options that potentially improve the monetary output per female herd animal without increasing the pressure onto natural rangelands. Taken together, the results of the study suggest that, despite an increase and intensification of cropping and vegetable gardening in the region of Qinghe, livestock rearing is still the major livelihood strategy both in terms of prevalence and relative importance. However, livestock keeping is challenged by low biomass production on rangelands, due to the combined impact of high climate variability and highly localized grazing pressure on the seasonal pastures. Though government regulations try to tackle the latter aspect, their implementation is sometimes difficult. Alternatives to strict regulation of grazing periods and animal numbers on seasonal pastures are, in the case of goats, more rigorous culling strategies and, in the case of sheep and goats, strategic supplementation of the animals in the winter and spring season. However, for the latter strategy to become economically viable, an improvement of live animal and meat marketing options and an investment in local meat processing facilities that add value to the carcasses is needed. As the regional cities grow rapidly, the potential market to absorb diverse and good quality meat products is there, along with the road network connecting Qinghe county to the regional capital. Such governmental measures will not only create new job opportunities in the region but also benefit the cash income of pastoralists in this westernmost region of China.

In NW of Portugal, the region between Esposende and Vila do Conde was established into a unique system called masseiras; masseiras are small fields that were created at the beginning of XX century by removing sand from dunes. Since the 80’s sand between closed masseiras has been removed giving way for larger fields, the “enlarged masseira with greenhouses”. This region is part of vulnerable zone nº1 (VZ1). Nowadays, the masseiras have almost disappeared; they had been replaced by “enlarged masseiras with plastic greenhouses” exploited by a new generation of growers. As water quality is an indicator of agriculture practices, 8 wells were selected and water samples were collected on four dates from September 2009 to May 2010. Laboratorial analysis was performed on nitrates and 28 pesticides. The results confirm that water in VZ1 is contaminated with nitrates (as it was expected) and also with pesticides. The water was contaminated in both dug wells and drilled wells all year round. Masseiras’ wells have more nitrates than greenhouses’ wells, probably due to poor agricultural practices used by growers who still employ high quantities of fertilizers and water. Pesticides detected in water samples include some that have been sprayed in the field and others that have not. Some forbidden substances were found. Our results confirm that, in VZ1, there is a diffusion contamination, which origin is unknown. In this communication, we put in picture the history of masseiras fields: how masseiras fields have been created and how they have disappeared; what trends exist in pest management strategies and the use of fertilizers, pesticides and water resources. These results reinforce the need to change the agricultural system in this region of traditional vegetable production.

Soil is a key resource that provides the basis of food production and sustains and delivers several ecosystems services including regulating and supporting services such as water and climate regulation, soil formation and the cycling of nutrients carbon and water. During the last decades, population growth, dietary changes and the subsequent pressure on food production, have caused severe damages on soil quality as a consequence of intensive, high input-based agriculture. While agriculture is supposed to maintain and steward its most important resource base, it compromises soil quality and fertility through its impact on erosion, soil organic matter and biodiversity decline, compaction, etc., and thus the necessary yield increases for the next decades. New or improved cropping systems and agricultural practices are needed to ensure a sustainable use of this resource and to fully take the advantages of its associated ecosystem services. Also, new and better soil quality indicators are crucial for fast and in-field soil diagnosis to help farmers decide on the best management practices to adopt under specific pedo-climatic conditions. Conservation Agriculture and its fundamental principles: minimum (or no) soil disturbance, permanent organic soil cover and crop rotation /intercropping certainly figure among the possibilities capable to guarantee sustainable soil management. The iSQAPER project – Interactive Soil Quality Assessment in Europe and China for Agricultural Productivity and Environmental Resilience – is tackling this problem with the development of a Soil Quality application (SQAPP) that links soil and agricultural management practices to soil quality indicators and will provide an easy-to-use tool for farmers and land managers to judge their soil status. The University of Évora is the leader of WP6 - Evaluating and demonstrating measures to improve Soil Quality. In this work package, several promising soil and agricultural management practices will be tested at selected sites and evaluated using the set of soil quality indicators defined for the SQAPP tool. The project as a whole and WP6 in specific can contribute to proof and demonstrate under different pedoclimatic conditions the impact of Conservation Agriculture practices on soil quality and function as was named the call under which this project was submitted.
