Full textAgricultural expansion and deforestation are complex processes. They are interlinked with different political, economic and social factors at local, national and interna- tional levels. This thesis is a preliminary and not exhastive attempt to analyse these problems in a global and systemic perspective. It studies one local case in peten guatemala, demostrating how agricultural modernization, tropical forest colonization and exportation led-growth have not been historically, the right answers to guatemalan forest development. On the contrary, they have given rise to poverty, violence and environmental degradation all over the country. Following the ecodevelopment principles the thesis proposes some elements of an agroforestry strategy to stop agricultural expansin and tropical forest deforestation. This strategy cant bi an up-down directional model. It has to articulate the global paradigme with democratic decision making at regional and local levels. It has also to coordinate social development with environmental items, promoting the political, institutional and technological changes needed for a sustainable forest development to exist. Finally, the thesis comes to the conclusion that only the peoples's participation and organization would allow a pressure strong enough over the different institutions and governements so as to make them to start implementing these changes. The thesis has four chapters, the firs studies the mains agricultural policies since the 1950s and their influence on the forest and on the living conditions of the rural people. It shows also, briefly, how the united state's agricultural policies had in, fluenced the guatemalan agricultural policies. The second chapter analyzes the agroforestry systems as a possible tool for building a sustainable forest development. The third sudies peten, inorder to undersatnd how the national agricultural policies have influenced the local development. Finally in the conclusions, the thesis proposes some elements for an agroforestry ecodevelopment strategy in guatemala

Full textAs concerns technological innovation, the searchers were used to consider that the users who introduce it do that simply obtain technical and economical performances. They have neglicted cetainly that the use of technology depends on what subject intend to do with and properly his manner to give it sense. We have seen across the appropriation of technologic innovatioin (tractor) by morocan farmers that the sense which require technology is not especially economical and techni (fonctional aspect). The subjects give sense to innovation according to their situation. Undoubtedly they act not only a farmers, but as family heads and society members also. The theory of activities system in which we have elaborate our approach has led us to evoke the representation of innovation. This representation can be fonctional, social, psycho-oci or psycho-affective. When the representation is fonctional the subject intend to realize some technical and economical performances. This is not the case when the representation is social because the subject give importance to the values o innovation. The subject can represent technology innovation as a mean to new relationships, this is psychosocial representation. Finaly he can intend to be considered as a person who has an esteem. It is wrong to imagine that farmers represent technology innovation exclusively according to one of the representations we have describe. It is only questio giving much more importance to a representation. This is the representation which go with the subject situation. We have postulated in begining that innovation is a reply to the disturbances that a subject feels in his his own situation. We postulated again that the innovation introduce the newx disturbances against what the subject tries to give new replies. Light of this we have seen that farmers are not the passive persons. The farmers are actives because they aren't dispose accept what the decidors want that they accept. They have their own rationaity according to which they give sense to events. The serious error a decidor can commit is to neglect this rationality

Full textThe liber ruralium commodorum, written by the Italian lawyer Pietro De'Crescenzi (Bologna, about 1230-1320), is the main treatise on agriculture bequeathed to us by the middle ages. Based on a wide philologic and codicologic study (part of latin text is published in the appendix) and on analysis of unedited documents from bologna archives, the thesis successively considers the agronomic renaissance, the treatise's contribution to history of North-Italian countryside, and its wide circulation. More than the author's knowledge or the scolastic way he manage his sources, the real originality of the book, in its cultural context, lies in its aim of providing an elogy of agriculture (that gives utilitas and delectatio) and in the return to ancient agronomy, which distinguishes it from literary production of its period (chap. 1-3). The main interest of the text is the informations it provides both about agrarian structures and practices (often confirmed by other data) and on the way in which the author, intellectual and landowner, looked at rural life (relations men nature, techniques of production, manor life are studied in chap. 4-6). Having discussed the manuscript transmission (chap. 7) and studied 14th and 15th century readers, the thesis concludes with the real interest shown this book by a broad public (from "ceto medio" to aristocracy), distant enough from rural realities to appreciate this treatise as an art of living in the countryside

Full textThis thesis focuses on the issue of the adoption and impact of technological innovations in agriculture. Its general objective is to analyze the adoption and impact of agricultural technological innovations disseminated by the West African Agricultural Productivity Program (WAAPP) in the maize and groundnut sectors in Senegal. Innovations are improved varieties of rain-fed maize and a machine for treating peanut oil against aflatoxins called the aflatoxin treatment table. To achieve the objective of our thesis, after a general introduction we have developed two chapters using a quantitative approach and a chapter using a qualitative approach. The first quantitative chapter focused on the analysis of the dynamic and adoption factors of improved maize seeds in Eastern Senegal and Haute Casamance. Results show that the path of improved maize seeds adoption Senegal follows a dynamic of several adopter groups and that the adoption factors can be heterogeneous between the groups. The second quantitative chapter evaluated the gender influence on agricultural technological innovations adoption and determined the factors of the results heterogeneity found through a meta-analysis involving 124 empirical studies. The results showed that on average being a woman has a negative and significant influence on the agricultural technologies adoption. This influence differs however when analyzed according to the type of agricultural technologies. Indeed it is negative and significant for improved seeds and not significant for fertilizer-type technologies or good agricultural practices. The qualitative chapter studied the adoption and effects of artisanal peanut oil treatment tables in groups in the peanut basin of Senegal. Results show that aflatoxin is a phenomenon whose consequences are not well known by the groups of women encountered. The adoption of the table was made entirely in some groups and partially in others. The adoption of the table increased the income of women's groups, improved the financial autonomy of women, improved their knowledge of aflatoxins, and strengthened their capacities.

Full textResearch on the propagation of agronomic GMOs in Europe has thus far focused on issues of political, economic and social regulation of this technological innovation, with emphasis on either a macroeconomic, sectoral or territorial type of approach, but has rarely attempted to combine the three. This thesis proposes a comprehensive approach to the governance issues posed by the propagation of this agronomic innovation, in terms of various spatial patterns and time scales, across extensive farming systems producing cereals (maize) and oilseeds (soybean, colza). Whether to replace chemical pesticides or to modify their conditions of use, seeds that have been genetically modified to tolerate specific herbicides and/or resist specific pests offer farmers new means for crop protection. How do the host environments react to the constraints imposed by the innovation? How do those environments reconcile the associated risks and benefits? In what ways are agrarian, social and mental structures likely to resist or on the contrary facilitate technical change? These were the questions that led us to undertake this work, joining the current of research on the dissemination of innovations in agriculture. We adopted a multi-scalar approach in order to gain an understanding of the stakes involved in the propagation of agronomic GMOs, not only at the global and European levels – and more specifically in two Member States, France and Italy – but also on an infra-national scale, in the regions of Emilia-Romagna and Moyenne-Garonne
La ricerca sulla diffusione degli OGM agronomici in Europa ha finora affrontato i problemi di regolazione politica, economica et sociale dell'innovazione da un punto di vista macroeconomico, settoriale o territoriale ma raramente essa a tentato una sintesi dei tre approcci. Questa tesi propone un approccio comprensivo ai problemi di "governanza" posti di la diffusione, a differenti scale spaziali et temporali, di una innovazione agronomica destinata al comparto delle grandi culture, più specificamente, al settore maidicolo e a quello delle oleaginose. Ora sostituendosi ai pesticidi chimici, ore modificandone le condizioni d'uso, le sementi modificate geneticamente per resistere agli attacchi di alcuni insetti o/e per tollerare certi erbicidi offrono agli agricoltori uno strumento supplementare per la protezione delle colture. Come viene valuto il rapporto rischi/benefici ? Di che natura sono la resistenze o le facilità che le strutture agrarie, sociali e mentali possono opporre o offrire al cambiamento ? Come regiscono i territori ai vincoli giuridici, normativi et tecnici impostidalle instituzioni ed dal mercato nonché dalla natura stessa dell'innovazione ? Tali sono i quesiti che ci hanno spinto ad intraprendere questo lavoro di ricerca che si inserisce nel vasto ambito degli studi sulla diffusione delle innovazioni in agricoltora. L'obiettivo che ci proponiamo é di far luce su alcune delle problematiche sollevate dalla diffusione degli OGM agronomici non solo a livello mondiale et europeo, et più specificamente in due Stati membri - l'Italia et la Francia - ma anche a livello infranazionale, in Emilia Romagna e in Moyenne-Garonne. Il nostro approccio é dunque multiscalare
