Pressoes e oposiçoes contra pequenos criadores familiares de gado bovino leiteiro da zona periurbana do Município de Castanhal (Pará, Brasil - Amazônia Oriental)

It is analyzed, in this paper, the conflicts involving a family of small dairy cattle breeders, faced with the opposition of society and restrictions imposed by the local authorities, against the livestock grazing on public lands in peri-urban zone of a medium-sized Amazonian city. The case study employed participant observation, interviews and document research. Despite the subordinate position occupied by the focused group in the credibility hierarchy of versions issued on the conflict, the group maintains a resistance conduct, based both in the need for sustenance, and in an attempt to preserve a way of life cherished by its members

La 'nueva ruralidad' en Cañuelas : Entre la agroecología y las nuevas urbanizaciones

Las transformaciones de la Región Metropolitana de Buenos Aires han impactado en territorios rurales. Es el caso de Cañuelas, donde "proyectos de desarrollo urbano" han avanzado, con lo cual desplazaron actividades agrícolas. No obstante, algunos de ellos intentan ser parte de la "nueva ruralidad" que se busca para el partido. Esta investigación exploratoria busca contribuir al estado del arte sobre "nueva ruralidad". Específicamente, indagamos sobre transformaciones territoriales y modelos de desarrollo que se disputan hegemonía en el territorio. Se utiliza un enfoque que conjuga estudios urbanos y rurales, una metodología cualitativa y basada en fuentes secundarias. Los resultados plantean una difícil convivencia entre usos del suelo.

Evaluation of Development Projects: a Process-Centered Approach in the Outskirts of Lima, Peru.

Development cooperation projects work with people involved in processes of change and social transformation. While the main objective of the intervention is the development process itself, the project?s quality will be determined by the way of implementing it. Its success lies in the sustainability of the generated processes and the connection with them by the involved actors. The evaluation analyses both aspects. This article examines the evaluation, under a process approach, of a project on urban agriculture in Lima (Peru). The results show that the use of this approach, which combines different evaluation tools, allows the identification and analysis of the processes with the involved members, providing a better understanding of the real sustainability of the results.

El Parque Agrario: estructura de preservación de los espacios agrarios en entornos urbanos en un contexto de cambio global

La propuesta del análisis de la figura de Parque Agrario en el ámbito español surge ante la constatación de que un nuevo paradigma está aconteciendo a escala estatal. Diversos focos se encuentran trabajando en paralelo, y de forma participada, en pos de la reformulación de las políticas públicas relacionadas con la agricultura periurbana. Estos focos ven en la figura de Parque Agrario un instrumento territorial que permite mejorar la sostenibilidad y cohesión territorial a través de la defensa de la gobernanza alimentaria local, sin olvidar la necesidad de conservación de los recursos naturales y el patrimonio paisajístico, junto a la prestación de múltiples servicios de los ecosistemas de estos ámbitos a la ciudadanía. Complementariamente, se empieza a vislumbrar el papel que esta figura puede desempeñar como herramienta de desarrollo territorial de los sistemas agrarios periurbanos, clave ante los efectos de carácter local que la globalización ejerce en estos territorios. La figura de Parque Agrario es una estructura que actúa bloqueando la base territorial, favoreciendo el desarrollo de la actividad agraria. Su mayor potencial es el de convertir el factor “proximidad urbana” de una amenaza a una oportunidad de desarrollo local endógeno que permita la continuidad de la agricultura, de los agricultores y del espacio agrario. La peculiaridad del Parque Agrario es que no es una figura al uso, estructurada y reglada por una legislación, sino que se trata de una iniciativa ad hoc, específica para cada caso, orientada a cumplir determinados objetivos de dinamización agraria, protección urbanística y valorización territorial. A pesar de la existencia de diversas definiciones y aportaciones sobre diferentes aspectos de la figura, no existe un análisis complejo de la misma en todas sus dimensiones, ni una tentativa de descripción de un modelo global y unitario del caso español y de sus potenciales resultados. Tampoco se han analizado en profundidad sus “invariantes” que se muestran como los elementos estructurantes del proyecto, capaces desarrollarse de forma diversa, de alcanzar diferentes niveles de complejidad, y de materializarse en función a las posibilidades que permita el marco normativo y legal. Por tanto, se plantea como objetivo principal de la tesis la definición de un modelo conceptual de Parque Agrario español, capaz de ser articulado e institucionalizado mediante un proceso de gobernanza, y que, como condición sine qua non sea duradero en el tiempo. Para poder llegar a describir un modelo colectivo se realiza, en primer lugar, un análisis genealógico que permita analizar sistemáticamente las propuestas desarrolladas en el ámbito español y los casos para establecer la existencia de una continuidad en la idea de Parque Agrario en las propuestas desarrolladas durante los últimos 25 años—sus invariantes—, y analice todos aquellos elementos que han ido enriqueciendo la figura en cada experiencia —sus variantes. Este análisis, además, ofrece como aportaciones el árbol genealógico y los mapas de dispersión de la figura y el primer catálogo de propuestas de Parque Agrario materializadas en proyecto. El resultado de la inducción de los datos obtenidos en el análisis genealógico es el modelo conceptual de Parque Agrario, que se define como una estructura orgánica de planificación-gestión-gobierno del territorio capaz de adaptarse a las necesidades específicas de todo sistema agrario periurbano que requiera la articulación-institucionalización de esta figura en él. Una vez descrito el modelo, se contrasta su fiabilidad mediante su aplicación como metodología de caracterización y evaluación de dos estudios de casos: uno exitoso, el Parque Agrario del Baix Llobregat, y uno frustrado, la propuesta de Parque Agrario de la Vega de Granada. ------------------------------------------------------ ABSTRACT -------------------------------------------------------------------- The proposed analysis of the figure of Agrarian Park in the Spanish sphere arises from the awareness that a new paradigm is happening at the state level. Different focuses are working in parallel, under participated programs, after the reformulation of public policies related to urban agriculture. These areas understand the figure of Agrarian Park as a territorial instrument for improving sustainability and territorial cohesion through the defense of local food governance, considering the need for conservation of natural resources and landscape heritage together with the multiple ecosystem services provided by these areas to the public. Additionally, the role that this figure can play as a tool for territorial development of peri-urban agrarian systems, which are key to the local effects that globalization has on these territories, is staring to be envisioned. The figure of Agrarian Park is a structure that works by blocking the territorial base to encourage the development of agrarian activity. Its greatest potential is to convert the threat of "urban proximity" into an opportunity for an endogenous local development that allows the persistence of agriculture, farmers and the agrarian space. The uniqueness of the Agrarian Park is that it is not a standard figure, structured and regulated by legislation, but rather an ad hoc initiative, specific to each case, designed to meet certain objectives of agrarian revitalization, urban protection and territorial enhance. Despite the existence of several definitions and contributions on different aspects of the figure, there is a lack of a complex analysis of it in all its dimensions, missing any attempt to describe a global and unitary model of the Spanish case and its potential outcomes. Its "invariants” have neither been evaluated in depth, shown as the structural elements of the project able to be developed in different ways, to achieve numerous levels of complexity, and to be materialized according to the possibilities allowed by the regulatory and legal framework. Therefore, the definition of a conceptual model of Spanish Agrarian Park able to be articulated and institutionalized through a process of governance, and durable over time as a sine qua non requisite, it is proposed as the main aim of the thesis. To get to describe a collective model, a genealogical analysis that systematically analyzes the proposals and cases developed in the Spanish field is undertaken to verify the existence of a continuity of the idea of Agrarian Park on the proposals developed during the past 25 years -invariants-, and evaluate all the elements that have enriched this figure in each experience - variants. This analysis also provides as inputs a family tree, maps of dispersion of the figure and the first catalog of Agrarian Park proposals materialized into projects. The result of inducting the data obtained in the genealogical analysis is the Conceptual Model of Agrarian Park, defined as an organic planning-management-government structure of the territory able to adapt to the specific needs of all peri-urban agrarian systems that require the articulation-institutionalization of this figure in it. Having described the model, its reliability is tested by applying it as a methodology for characterization and evaluation of two case studies, one successful, the Baix Llobregat Agrarian Park, and one frustrated, the proposed Agrarian Park de la Vega of Granada.

Assessing local food systems in China for building healthy mega-cities

Despite the long-lasting concern for food security in China at the national level, policy attempts to cope with this issue have often resulted to be ineffective. More importantly, they have rarely addressed the question from a local perspective. International experiences of urban food strategies proved to be quite efficacious in enhancing the local provision of food and improving the overall city sustainability by shortening the supply chain, preserving peri-urban areas and improving the nutrition of citizens. By reviewing existing practices of city farming in China, mainly ascribable to urban agriculture experiences, the intention of this paper is to reflect upon the challenges of implementing more comprehensive local food systems. In the conclusion the paper argues that, given the current institutional, socio-economic, and environmental constrains of Chinese cities there is a need of introducing holistic planning tool to assess local food systems in order to ensure the building of real healthy cities.

Garden Cities: A flawed model for Ecological Urbanism?

Since the beginning of the 20th century, the Garden City model has been a predominant theory emerging from Ecological Urbanism. In his book Howard observed the disastrous effects of rapid urbanization and as a response, proposed the Garden City. Although Howard’s proposal was first published in the late 1800’s, the clear imbalance that Howard aimed to address is still prevalent in the UK today. Each year, the UK wastes nearly 15 million tons of food, despite this an estimated 500,000 people in the UK go without sufficient access to food. While the urban population is rapidly increasing and cities are becoming hubs of economic activity, producing wealth and improving education and access to markets, it is within these cities that the imbalance is most evident, with a significant proportion of the world’s population with unmet needs living in urban areas. Despite Howard’s model being a response to 17th century London, many still consider the Garden City model to be an effective solution for the 21st century. In his book, Howard details the metrics required for the design of a Garden City. This paper will discuss how, by using this methodology and comparing it with more recent studies by Cornell University and Matthew Wheeland (Pure Energies); it is possible to test the validity of Howard’s proposal to establish whether the Garden City model is a viable solution to the increasing pressures of urbanization.
This paper outlines how the analysis of Howard’s proposal has shown the model to be flawed, incapable of producing enough food to sustain the proposed 32,000 population, with a capacity to produce only 23% of the food required to meet the current average UK consumption rate. Beyond the limited productive capacity of Howard’s model, the design itself does little to increase local resilience or the ecological base. This paper will also discuss how a greater understanding of the
Land-share requirements enables the design of a new urban model, building on the foundations initially laid out by Howard and combining a number of other theories to produce a more resilient and efficient model of ecological urbanism.

Soil-less systems vs. soil-based systems for cultivating edible plants on buildings in relation to the contribution towards sustainable cities

Food production and consumption for cities has become a global concern due to increasing numbers of people living in urban areas, threatening food security. There is the contention that people living in cities have become disconnected with food production, leading to reduced nutrition in diets and increased food waste. Integrating food production into cities (urban agriculture) can help alleviate some of these issues. Lack of space at ground level in high-density urban areas has accelerated the idea of using spare building surfaces for food production. There are various growing methods being used for food production on buildings, which can be split into two main types, soil-less systems and soil-based systems. This paper is a holistic assessment (underpinned by the triple bottom line of sustainable development) of these two types of systems for food production on buildings, looking at the benefits and limitation of each type in this context. The results illustrate that soil-less systems are more productive per square metre, which increases the amount of locally grown, fresh produce available in urban areas. The results also show that soil-based systems for cultivation on buildings are more environmentally and socially beneficial overall for urban areas than soil-less systems.
