Planting coconuts in Indian villages: ethnoecological aspects and evaluation of a "sustainable development" project

Apesar de cientistas e tomadores de decisão abraçarem o conceito geral de "desenvolvimento sustentável", há pouco acordo sobre como se atingir esta meta em situações específicas. Assim, projetos de desenvolvimento sustentável são amplamente criticados por etno-cientistas quanto à forma como são inter-culturalmente formulados. Aqui reportamos um caso controverso de plantio de coco-da-Bahia em aldeias Kayapó do sul do Pará, e fazemos a nossa autocrítica. Nós partimos da premissa de que o reflorestamento e o estado geral de saúde/nutrição caminham lado a lado. Portanto, o desenvolvimento da cultura de cocos por si só deve contribuir para a conservação da floresta no longo prazo e, simultaneamente, contribuir para o bom estado nutricional do povo Kayapó que protege a floresta da ameaça de práticas não-sustentáveis. Nós buscamos descobrir como que o comportamento dos Kayapó afeta o desenvolvimento da cultura de cocos quando amparada com suporte externo. Nós apresentamos resultados de duas viagens de campo para a terra Kayapó, onde detectamos fatores sócio-ecológicos relevantes para o sucesso de nosso projeto de apoio à cultura de coqueiros nas aldeias indígenas. Primeiro, em novembro de 2007, nós visitamos as aldeias Kikretum, Moikarakô e Aukre (dentre 10 aldeias que receberam mudas de coqueiros de nosso programa de apoio) para entregar um segundo carregamento de mudas de coqueiro (o primeiro carregamento aconteceu em abril de 2006). E descrevemos quantitativamente um aspecto do comportamento dos dispersores de sementes de coco (os Kayapó). Especificamente, como as palmeiras pré-existentes nas aldeias são distribuídas dentre as famílias dos índios e como este carregamento sobreviveu a fatores etno-ecológicos. Segundo, em julho de 2008 nós visitamos as aldeias Kokraimoro e Pykararankre e estimamos a posição dos coqueiros pré-existentes e dos novos em relação a outras árvores cultivadas, fazendo uso de censos partindo do centro das aldeias para seus limites exteriores. Nas três aldeias indígenas visitadas em 2007, virtualmente todos os coqueiros pré-existentes pertenciam a poucas famílias e a distribuição de frutos era, na maior parte dos casos, altamente concentrada dentre os membros destas famílias. Entretanto, assumindo que todos os coqueiros jovens que sobreviveram ao primeiro ano chegarão à maturidade (do primeiro carregamento em abril de 2006), eles representam um aumento considerável no numero projetado de coqueiros adultos nas três aldeias visitadas (48, 195 e 101% em Kikretum, Moikarakô e Aukre, respectivamente). E uma redução substancial na desigualdade de acesso aos cocos. Na expedição de 2008, encontramos que os índios geralmente plantam coqueiros bem próximos das suas casas onde a competição com outras árvores cultivadas podem limitar o desenvolvimento das palmeiras.

Apontamentos críticos para o tratamento da questão ambiental na perspectiva da emancipação

The belief in the existence of an ecological crisis that would affect the future of the planet, is one of the factors that causes the appearance of ecological concern, resulting in the adoption of non-predatory consumer practices and more respectful relationships with non-humans beings. This study starts from the assumption of the existence of an environmental question, and aims to investigate some of the cultural causes of human predation and identify possible ways in which environmental question can be treated critically to search overcomes. Follows the reasoning that western society as a complex of social relations, the capitalism, as a mode of production utilities and rational right, are all consequences of the modern rationality, cognitive and moral logic that transforms people and nature in satisfaction instruments of individual interests. However, despite being identified as the causative root of environmental question, modern rationality takes with it enough to promote the development of ecological respect, necessary in confronting and overcoming the environmental question, as it will be applied as a principle in redefinition of the relationship of human beings with themselves and with nature. And modern rationality can also make capitalism more efficient in the use and reuse of materials so as to consume fewer resources on the planet to satisfy human needs.

Análise matemática e estatística da produtividade de lavouras cafeeiras agroquímica e orgânica na região da alta paulista

Studies with organic systems have shown the feasibility and ecological and social sustainability of these agroecosystems, unlike the systems agrochemicals (conventional) production. Some studies have concluded that for the model agrochemical exists less interaction between the flow of internal energy, basically the crop receives all inputs to production with no increase in "energy quality" within the system, while in the organic model of production has increased interaction between different resources in the system. The current economic and ecological crisis, exposed no sustainability of the production pattern of industrialized agriculture developed in a way, showing the dependence of developed countries on imports of agricultural commodities produced in the third world, among there coffee. Given these facts, developed a survey to identify problems in the Alta Paulista region, west of São Paulo State, in relation to coffee production systems. Actually, the fundamental problem, according to the research, farmers in this region, is to choose a viable production system correctly (environmental, social and economic); agrochemical or organic. The objectives of this study were to analyze the yield of production systems and agro-chemical and organic coffee in the period from 2003 to 2007, in 30 producing properties, located in this region, in order to point the production system to produce the highest yield. According to the methodology of CONAB, data collected were recorded on spreadsheets to be used as variables in statistical analysis models and mathematics. We performed a descriptive analysis of productivity data and were used for statistical analysis tests for parametric and nonparametric analysis of variance. The mathematical analyses of the curves were prepared with Origin for Windows 6.0 software, which uses numerical methods to fit the data supplied to a function of variable parameters. Unlike conventional systems of production, the organic system showed greater viability of the production model. Furthermore, with the quantitative modeling proposal, it is possible to perform the evaluation of these types of investments, providing more security to the farmer at the time of decision.

Food Competition in a Semi-Free-Ranging Cebus apella Group

The competitive regime faced by individuals is fundamental to modelling the evolution of social organization. In this paper, we assess the relative importance of contest and scramble food competition on the social dynamics of a provisioned semi-free-ranging Cebus apella group (n=18). Individuals competed directly for provisioned and clumped foods. Effects of indirect competition were apparent with individuals foraging in different areas and with increased group dispersion during periods of low food abundance. We suggest that both forms of competition can act simultaneously and to some extent synergistically in their influence on social dynamics; the combination of social and ecological opportunities for competition and how those opportunities are exploited both influence the nature of the relationships within social groups of primates and underlie the evolved social structure.

La filosofia di Hans-Georg Gadamer e il problema del disagio della modernità. Ermeneutica, estetica, etica e politica

L’ermeneutica filosofica di Hans-Georg Gadamer – indubbiamente uno dei capisaldi del pensiero novecentesco – rappresenta una filosofia molto composita, sfaccettata e articolata, per così dire formata da una molteplicità di dimensioni diverse che si intrecciano l’una con l’altra. Ciò risulta evidente già da un semplice sguardo alla composizione interna della sua opera principale, Wahrheit und Methode (1960), nella quale si presenta una teoria del comprendere che prende in esame tre differenti dimensioni dell’esperienza umana – arte, storia e linguaggio – ovviamente concepite come fondamentalmente correlate tra loro. Ma questo quadro d’insieme si complica notevolmente non appena si prendano in esame perlomeno alcuni dei numerosi contributi che Gadamer ha scritto e pubblicato prima e dopo il suo opus magnum: contributi che testimoniano l’importante presenza nel suo pensiero di altre tematiche. Di tale complessità, però, non sempre gli interpreti di Gadamer hanno tenuto pienamente conto, visto che una gran parte dei contributi esegetici sul suo pensiero risultano essenzialmente incentrati sul capolavoro del 1960 (ed in particolare sui problemi della legittimazione delle Geisteswissenschaften), dedicando invece minore attenzione agli altri percorsi che egli ha seguito e, in particolare, alla dimensione propriamente etica e politica della sua filosofia ermeneutica. Inoltre, mi sembra che non sempre si sia prestata la giusta attenzione alla fondamentale unitarietà – da non confondere con una presunta “sistematicità”, da Gadamer esplicitamente respinta – che a dispetto dell’indubbia molteplicità ed eterogeneità del pensiero gadameriano comunque vige al suo interno. La mia tesi, dunque, è che estetica e scienze umane, filosofia del linguaggio e filosofia morale, dialogo con i Greci e confronto critico col pensiero moderno, considerazioni su problematiche antropologiche e riflessioni sulla nostra attualità sociopolitica e tecnoscientifica, rappresentino le diverse dimensioni di un solo pensiero, le quali in qualche modo vengono a convergere verso un unico centro. Un centro “unificante” che, a mio avviso, va individuato in quello che potremmo chiamare il disagio della modernità. In altre parole, mi sembra cioè che tutta la riflessione filosofica di Gadamer, in fondo, scaturisca dalla presa d’atto di una situazione di crisi o disagio nella quale si troverebbero oggi il nostro mondo e la nostra civiltà. Una crisi che, data la sua profondità e complessità, si è per così dire “ramificata” in molteplici direzioni, andando ad investire svariati ambiti dell’esistenza umana. Ambiti che pertanto vengono analizzati e indagati da Gadamer con occhio critico, cercando di far emergere i principali nodi problematici e, alla luce di ciò, di avanzare proposte alternative, rimedi, “correttivi” e possibili soluzioni. A partire da una tale comprensione di fondo, la mia ricerca si articola allora in tre grandi sezioni dedicate rispettivamente alla pars destruens dell’ermeneutica gadameriana (prima e seconda sezione) ed alla sua pars costruens (terza sezione). Nella prima sezione – intitolata Una fenomenologia della modernità: i molteplici sintomi della crisi – dopo aver evidenziato come buona parte della filosofia del Novecento sia stata dominata dall’idea di una crisi in cui verserebbe attualmente la civiltà occidentale, e come anche l’ermeneutica di Gadamer possa essere fatta rientrare in questo discorso filosofico di fondo, cerco di illustrare uno per volta quelli che, agli occhi del filosofo di Verità e metodo, rappresentano i principali sintomi della crisi attuale. Tali sintomi includono: le patologie socioeconomiche del nostro mondo “amministrato” e burocratizzato; l’indiscriminata espansione planetaria dello stile di vita occidentale a danno di altre culture; la crisi dei valori e delle certezze, con la concomitante diffusione di relativismo, scetticismo e nichilismo; la crescente incapacità a relazionarsi in maniera adeguata e significativa all’arte, alla poesia e alla cultura, sempre più degradate a mero entertainment; infine, le problematiche legate alla diffusione di armi di distruzione di massa, alla concreta possibilità di una catastrofe ecologica ed alle inquietanti prospettive dischiuse da alcune recenti scoperte scientifiche (soprattutto nell’ambito della genetica). Una volta delineato il profilo generale che Gadamer fornisce della nostra epoca, nella seconda sezione – intitolata Una diagnosi del disagio della modernità: il dilagare della razionalità strumentale tecnico-scientifica – cerco di mostrare come alla base di tutti questi fenomeni egli scorga fondamentalmente un’unica radice, coincidente peraltro a suo giudizio con l’origine stessa della modernità. Ossia, la nascita della scienza moderna ed il suo intrinseco legame con la tecnica e con una specifica forma di razionalità che Gadamer – facendo evidentemente riferimento a categorie interpretative elaborate da Max Weber, Martin Heidegger e dalla Scuola di Francoforte – definisce anche «razionalità strumentale» o «pensiero calcolante». A partire da una tale visione di fondo, cerco quindi di fornire un’analisi della concezione gadameriana della tecnoscienza, evidenziando al contempo alcuni aspetti, e cioè: primo, come l’ermeneutica filosofica di Gadamer non vada interpretata come una filosofia unilateralmente antiscientifica, bensì piuttosto come una filosofia antiscientista (il che naturalmente è qualcosa di ben diverso); secondo, come la sua ricostruzione della crisi della modernità non sfoci mai in una critica “totalizzante” della ragione, né in una filosofia della storia pessimistico-negativa incentrata sull’idea di un corso ineluttabile degli eventi guidato da una razionalità “irrazionale” e contaminata dalla brama di potere e di dominio; terzo, infine, come la filosofia di Gadamer – a dispetto delle inveterate interpretazioni che sono solite scorgervi un pensiero tradizionalista, autoritario e radicalmente anti-illuminista – non intenda affatto respingere l’illuminismo scientifico moderno tout court, né rinnegarne le più importanti conquiste, ma più semplicemente “correggerne” alcune tendenze e recuperare una nozione più ampia e comprensiva di ragione, in grado di render conto anche di quegli aspetti dell’esperienza umana che, agli occhi di una razionalità “limitata” come quella scientista, non possono che apparire come meri residui di irrazionalità. Dopo aver così esaminato nelle prime due sezioni quella che possiamo definire la pars destruens della filosofia di Gadamer, nella terza ed ultima sezione – intitolata Una terapia per la crisi della modernità: la riscoperta dell’esperienza e del sapere pratico – passo quindi ad esaminare la sua pars costruens, consistente a mio giudizio in un recupero critico di quello che egli chiama «un altro tipo di sapere». Ossia, in un tentativo di riabilitazione di tutte quelle forme pre- ed extra-scientifiche di sapere e di esperienza che Gadamer considera costitutive della «dimensione ermeneutica» dell’esistenza umana. La mia analisi della concezione gadameriana del Verstehen e dell’Erfahrung – in quanto forme di un «sapere pratico (praktisches Wissen)» differente in linea di principio da quello teorico e tecnico – conduce quindi ad un’interpretazione complessiva dell’ermeneutica filosofica come vera e propria filosofia pratica. Cioè, come uno sforzo di chiarificazione filosofica di quel sapere prescientifico, intersoggettivo e “di senso comune” effettivamente vigente nella sfera della nostra Lebenswelt e della nostra esistenza pratica. Ciò, infine, conduce anche inevitabilmente ad un’accentuazione dei risvolti etico-politici dell’ermeneutica di Gadamer. In particolare, cerco di esaminare la concezione gadameriana dell’etica – tenendo conto dei suoi rapporti con le dottrine morali di Platone, Aristotele, Kant e Hegel – e di delineare alla fine un profilo della sua ermeneutica filosofica come filosofia del dialogo, della solidarietà e della libertà.

Sustainability indicators for environmental management and decision making

The general objective of this research is to explore theories and methodologies of sustainability indicators, environmental management and decision making disciplines with the operational purpose of producing scientific, robust and relevant information for supporting system understanding and decision making in real case studies. Several tools have been applied in order to increase the understanding of socio-ecological systems as well as providing relevant information on the choice between alternatives. These tools have always been applied having in mind the complexity of the issues and the uncertainty tied to the partial knowledge of the systems under study. Two case studies with specific application to performances measurement (environmental performances in the case of the K8 approach and sustainable development performances in the case of the EU Sustainable Development Strategy) and a case study about the selection of sustainable development indicators amongst Municipalities in Scotland, are discussed in the first part of the work. In the second part of the work, the common denominator among subjects consists in the application of spatial indices and indicators to address operational problems in land use management within the territory of the Ravenna province (Italy). The main conclusion of the thesis is that a ‘perfect’ methodological approach which always produces the best results in assessing sustainability performances does not exist. Rather, there is a pool of correct approaches answering different evaluation questions, to be used when methodologies fit the purpose of the analysis. For this reason, methodological limits and conceptual assumptions as well as consistency and transparency of the assessment, become the key factors for assessing the quality of the analysis.

An interdisciplinary analysis of obesity: theory and empirical evidence

The dissertation is structured in three parts. The first part compares US and EU agricultural policies since the end of WWII. There is not enough evidence for claiming that agricultural support has a negative impact on obesity trends. I discuss the possibility of an exchange in best practices to fight obesity. There are relevant economic, societal and legal differences between the US and the EU. However, partnerships against obesity are welcomed. The second part presents a socio-ecological model of the determinants of obesity. I employ an interdisciplinary model because it captures the simultaneous influence of several variables. Obesity is an interaction of pre-birth, primary and secondary socialization factors. To test the significance of each factor, I use data from the National Longitudinal Survey of Adolescent Health. I compare the average body mass index across different populations. Differences in means are statistically significant. In the last part I use the National Survey of Children Health. I analyze the effect that family characteristics, built environment, cultural norms and individual factors have on the body mass index (BMI). I use Ordered Probit models and I calculate the marginal effects. I use State and ethnicity fixed effects to control for unobserved heterogeneity. I find that southern US States tend have on average a higher probability of being obese. On the ethnicity side, White Americans have a lower BMI respect to Black Americans, Hispanics and American Indians Native Islanders; being Asian is associated with a lower probability of being obese. In neighborhoods where trust level and safety perception are higher, children are less overweight and obese. Similar results are shown for higher level of parental income and education. Breastfeeding has a negative impact. Higher values of measures of behavioral disorders have a positive and significant impact on obesity, as predicted by the theory.

Farming Systems and Resilience Building in a Changing Climate On-Farm Comparisons of Organic and Conventional Cocoa Cultivation in Alto Beni, Bolivia

Resilience research has been applied to socioeconomic as well as for agroecological studies in the last 20 years. It provides a conceptual and methodological approach for a better understanding of interrelations between the performance of ecological and social systems. In the research area Alto Beni, Bolivia, the production of cocoa (Theobroma cacao L.), is one of the main sources of income. Farmers in the region have formed producers’ associations to enhance organic cocoa cultivation and obtain fair prices since the 1980s. In cooperation with the long-term system comparisons by the Research Institute of Organic Agriculture (FiBL) in Alto Beni, aspects of the field trial are applied for the use in on-farm research: a comparison of soil fertility, biomass and crop diversity is combined with qualitative interviews and participatory observation methods. Fieldwork is carried out together with Bolivian students through the Swiss KFPE-programme Echanges Universitaires. For the system comparisons, four different land-use types were classified according to their ecological complexity during a preliminary study in 2009: successional agroforestry systems, simple agroforestry systems (both organically managed and certified), traditional systems and conventional monocultures. The study focuses on interrelations between different ways of cocoa cultivation, livelihoods and the related socio-cultural rationales behind them. In particular this second aspect is innovative as it allows to broaden the biophysical perspective to a more comprehensive evaluation with socio-ecological aspects thereby increasing the relevance of the agronomic field studies for development policy and practice. Moreover, such a socio-ecological baseline allows to assess the potential of organic agriculture regarding resilience-building face to socio-environmental stress factors. Among others, the results of the pre-study illustrate local farmers’ perceptions of climate change and the consequences for the different crop-systems: all interviewees mentioned rising temperatures and/or an extended dry season as negative impacts more with regard to their own working conditions than to their crops. This was the case in particular for conventional monocultures and in plots where slash-and-burn cultivation was practised whereas for organic agroforestry systems the advantage of working in the shade was stressed indicating that their relevance rises in the context of climate change.

Indigenous fodder trees can increase grazing accessibility for landless and mobile pastoralists in northern Pakistan

Degraded hillsides in Northern Pakistan are rehabilitated through social forestry campaigns using fast growing exotic trees. These plantations on former scrublands curtail access by livestock owned by landless pastoralists and create social tension. This study proposes an alternative strategy of planting indigenous fodder trees and shrubs that are well-suited to the local socio-ecological characteristics and can benefit all social segments. The choice of fodder tree species, their nutritional value and distribution within the complex socio-ecological system is explained. This study also explores the suitability of these trees at different elevations, sites and transhumant routes. Providing mobile herders with adequate fodder trees could relax social tensions and complement food security.

Mainstreaming a Decade's Experiences in Watershed Management to Meet the Challenges of Environmental Change in the Hindu Kush-Himalayas

Like other mountain areas in the world, the Hindu Kush-Himalayan (HKH) region is particularly vulnerable to climate change. Ongoing climate change processes are projected to have a high impact on the HKH region, and accelerated warming has been reported in the Himalayas. These climate change impacts will be superimposed on a variety of other environmental and social stresses, adding to the complexity of the issues. The sustainable use of natural resources is crucial to the long-term stability of the fragile mountain ecosystems in the HKH and to sustain the socio-ecological resilience that forms the basis of sustainable livelihoods in the region. In order to be prepared for these challenges, it is important to take stock of previous research. The ‘People and Resource Dynamics Project’ (PARDYP), implemented by International Centre for Integrated Mountain Development (ICIMOD), provides a variety of participatory options for sustainable land management in the HKH region. The PARDYD project was a research for development project that operated in five middle mountain watersheds across the HKH – two in Nepal and one each in China, India, and Pakistan. The project ran from 1996 to 2006 and focused on addressing the marginalisation of mountain farmers, the use and availability of water, issues relating to land and forest degradation and declining soil fertility, the speed of regeneration of degraded land, and the ability of the natural environment to support the growing needs of the region’s increasing population. A key learning from the project was that the opinion of land users is crucial to the acceptance (and, therefore, successful application) of new technologies and approaches. A major challenge at the end of every project is to promote knowledge sharing and encourage the cross-fertilization of ideas (e.g., in the case of PARDYP, with other middle mountain inhabitants and practitioners in the region) and to share lessons learned with a wider audience. This paper will highlight how the PARDYP findings, including ways of addressing soil fertility and water scarcity, have been mainstreamed in the HKH region through capacity building (international, regional, and national training courses), networking, and the provision of backstopping services. In addition, in view of the challenges in watershed management in the HKH connected to environmental change, the lessons learned from the PARDYP are now being used by ICMOD to define and package climate change proof technology options to address climate change adaptation.

Structural and procedural properties important in promoting bio-enterprises as alternative livelihoods to pastoral and agro-pastoral livelihoods

Alternative livelihoods to pastoral and agro-pastoral livelihoods are increasingly gaining attention in rural development but few empirical evidence exist on how to go about supporting such initiatives. As pastoral and agro-pastoral production conditions change due to various factors including market conditions, climate variability and change, pastoralists and agro-pastoralists are increasingly faced with the challenge of finding alternative livelihoods. Bio-enterprises offer such alternatives or complementary activities for rural actors to adapt to changing socio-ecological conditions. This study examines the roles of bio-enterprise initiatives from a livelihood perspective and identifies the features important for such initiatives to reduce poverty and improve the adaptive capacities of pastoralists and agro-pastoralists. It draws on four different bio-enterprise initiatives on agro-pastoral and pastoral livelihoods and on improved natural resources management (NRM) in the drylands of Kenya. Data were collected through interviews, focus group discussions, informal discussions and the study of reports. Results shows among other factors that diversification into enterprises requires cooperation among the stakeholders with their varying experiences in development, NRM and business development. Other factors such as sustained financial support, capacity development to survive the market introduction phase, as well as quantity and quality of the product, are critical. Mentoring proved to be a driver of success in some initiatives.

At the Interface of Culture, Development, and Forests: Insights from Bolivia and Kenya

The first part summarises the origins, definitions and debates around the general notions of development, culture and associated more specific concepts such as identity, tradition, exogenous and endogenous knowledge, institutions, governance or territoriality. A second part highlights how culture and development got related to the debates around sustainable governance of natural resources and forests. The third part illustrates on the basis of a case study from Kenya and Bolivia how culture as a transversal element of forest governance is expressed in empirical terms. Moreover it is shown how the cultural dimension affects positively or negatively the outcomes of culturally shaped forest governance outcomes and the role these effects play in shaping the sustainability of the socio-ecological systems of forests in Africa and South America.
