Agricultores familiares da região sul da Amazônia Brasileira: uma contribuição à crise ecológica global. Repositório Alice
ABREU, L. S. de; SANTOS, A. da S. dos; WATANABE, M. A..
Resumo: Poucos estudos têm analisado o papel da população amazônica para a conservação ecológica da biodiversidade e para a redução dos efeitos da crise ecológica global. Esse estudo aborda experiências com Sistemas Agroflorestais (SAF?s) desenvolvida pela Associação de Produtores Alternativos (APA), em Ouro Preto do Oeste ? RO. O objetivo foi o de verificar se é possível conciliar a conservação ambiental com o desenvolvimento da agricultura familiar no sul da Amazônia. A hipótese é que a agrobiodiversidade associada aos sistemas agroflorestais contribui para a minimização da crise ambiental global. Essa afirmação se contrapõe ao velho diagnóstico de culpar os agricultores menos favorecidos economicamente pela destruição das florestas. O estudo documentou...

Agroforestry systems among small farmers in the southern Brazilian Amazon region: social resilience to the global ecological crisis. Repositório Alice
ABREU, L. S. de; BELLON, S..
Few studies have analysed the role of Amazonian populations for ecological conservation of the biodiversity and for the reduction of local climatic changes. This study address an experience with Agroforestal Systems (AFSs) developed by Alternative Producers Association (APA) in Ouro Preto do Oeste, Rondônia State. The hypothesis is that the agrobiodiversity associated to agroforestry systems would contribute to the minimization of the global environmental crisis and at the same time provide goods utilized in these producers food and living. The paper investigates the possibility of conciliating the environmental conservation with the expansion of small farming in Amazon promoting agrobiodiversity along with the improvement of food sovereignty. The...

Channeling consumption preferences for co-existence of landrace and modern varieties in-situ AgEcon
Krishna, Vijesh V.; Pascual, Unai; Zilberman, David.
The study examines the least-cost option of conserving landraces in-situ by the development of market friction instruments. The empirical examination is comprised of two closely-related studies on eggplant production and consumption sectors of India. An examination of the cost and return structure of eggplant farming in the study area reveals that the incremental farm price of eggplant products of landrace origin eclipses the yield advantage of hybrid varieties. Possibly due to the information asymmetries and other imperfections existing in this market, the price increment currently realized by the eggplant farmers is still only a fraction of consumers’ willingness to pay for landraces. This wide margin is indicative of the unexploited potential of...

Collective Action and Marketing of Underutilized Plant Species: The Case of Minor Millets in Kolli Hills, Tamil, Nadu, India AgEcon
Gruere, Guillaume P.; Nagarajan, Latha; King, E.D.I. Oliver.
Minor millets are examples of underutilized plant species, being locally important but rarely traded internationally with an unexploited economic potential. In the Kolli hills of Tamil Nadu, India, a genetically diverse pool of minor millet varieties are grown by the tribal farming communities to meet their subsistence food needs. Most of these minor crops were not traded outside the farming community. Despite a consumption preference among the farming communities for minor millets, in the recent past the acreage under minor millet crops have declined considerably due to the availability of substitute cash crops. As a response, the M.S. Swaminathan Research Foundation (MSSRF) based in Chennai has led targeted conservation cum commercialization intervention...

Collective Action in Plant Genetic Resources Management: Gendered Rules of Reputation, Trust and Reciprocity in Kerala, India AgEcon
Padmanabhan, Martina Aruna.
Collective action aims at the joint management of common pool resources. Agrobiodiversity at the community level is conceptualized as a collective resource requiring the management of varieties, species and their interrelations within a farming-system. In the rice dominated agriculture in the uplands of Kerala, India, few community groups continue maintaining and thus conserving their high diversity in landraces. Faced with the challenges of devastating prices for rice, their traditional system of collective action to exchange seed material and knowledge is endangered. A new institutional mechanism to manage biodiversity is the People’s Biodiversity Register, a mandatory documentation procedure to enable cost and benefit sharing under the Convention on...

Combining revealed and stated preference methods to assess the private value of agrobiodiversity in Hungarian home gardens AgEcon
Birol, Ekin; Kontoleon, Andreas; Smale, Melinda.
Hungarian home gardens are small-scale farms managed by farm households using traditional management practices and family labor. They generate private benefits for farmers by enhancing diet quality and providing food when costs of transacting in local markets are high. Home gardens also generate public benefits for society by supporting long-term productivity advances in agriculture. In this paper, we estimate the private value to farmers of agrobiodiversity in home gardens. Building on the approach presented in EPTD Discussion Paper 117 (2004), we combine a stated preference approach (a choice experiment model) and a revealed preference approach (a discrete-choice, farm household model). Both models are based on random utility theory. To combine the...

DETERMINANTS OF CEREAL DIVERSITY IN COMMUNITIES AND ON HOUSEHOLD FARMS OF THE NORTHERN ETHIOPIAN HIGHLANDS AgEcon
Benin, Samuel; Gebremedhin, Berhanu; Smale, Melinda; Pender, John L.; Ehui, Simeon K..
On farm conservation of crop diversity poses obvious policy challenges in terms of the design of appropriate incentive mechanisms and possible trade-offs between conservation and productivity. This paper compares factors explaining the inter-specific diversity (diversity among species) and infra-specific diversity (diversity among varieties within a species) of cereal crops grown in communities and on individual farms in the northern Ethiopian highlands. Using named varieties and ecological indices of spatial diversity (richness, evenness, and inverse dominance), we find that a combination of factors related to the agro-ecology of a community, its access to markets, and the characteristics of its households and farms significantly affect both the inter-...

Economics and Biodiversity in Intensively Managed Agro-Ecosystems AgEcon
Russell, Noel P.; Pascual, Unai; Omer, Amani A..
This paper explores the dynamic effects of biodiversity conservation on agricultural production in the context of specialised intensive farming systems. The focus is on the analysis of the dynamic effects of changes in the levels of agrobiodiversity, on technical change and productivity in intensive agricultural systems. A theoretical model is used to derive hypotheses regarding these linkages that are empirically tested using a stochastic production frontier model with data from a panel of UK cereal farms for the period 1989-2000. The results suggest that the increased agrobiodiversity has positively helped to shift the production frontier outwards. This indicates that the evolution of an intensive agricultural system to less intensive use of inputs can...

Good year, bad year: changing strategies, changing networks? A two-year study on seed acquisition in northern Cameroon Ecology and Society
Analysis of seed exchange networks at a single point in time may reify sporadic relations into apparently fixed and long-lasting ones. In northern Cameroon, where environment is not only strongly seasonal but also shows unpredictable interannual variation, farmers’ social networks are flexible from year to year. When adjusting their strategies, Tupuri farmers do not systematically solicit the same partners to acquire the desired propagules. Seed acquisitions documented during a single cropping season may thus not accurately reflect the underlying larger social network that can be mobilized at the local level. To test this hypothesis, we documented, at the outset of two cropping seasons (2010 and 2011), the relationships through which seeds were...

Knowing Agricultural Biodiversity OceanDocs
Mulvany, P..
The term "agricultural biodiversity" is relatively recent, perhaps post-CBD. Although, the specific nature of the biodiversity used by people was recognised for a long time, the overwhelming emphasis in the CBD was on general biodiversity, mainly 'wild' flora and fauna that inhabit this fragile biosphere in which people also live.

Sementes crioulas: o estado da arte no Rio Grande do Sul AgEcon
Pelwing, Andreia Becker; Frank, Lucia Brandao; Barros, Ingrid I. Bergman de.
This study investigated the state of the art of traditional, or landrace seeds in the State of Rio Grande do Sul. An ethnographic study was carried out by means of a non-statistical seed sampling in 13 farms from eight municipalities lying in the regions of the Greater Porto Alegre, Serra, Planalto Médio, Depressão Central and Serra do Sudeste. A broad diversity of ancient plants was observed. These species survive in the farms with the help of a seed bank. All in all, 39 plant species were characterized, distributed in 12 families, totaling 258 instances of landrace seeds grown in the farms visited. According to the farmers, the preference for landrace seeds is due chiefly to seed adaptability, better flavor and quality of the produce grown therefrom,...

Technology, preferences and the sustainable intensification of agricultural production AgEcon
Russell, Noel P.; Omer, Amani A.; Pascual, Unai.
This paper addresses the relationship between agrobiodiversity conservation and sustainable agricultural intensification. A stylised theoretical model is used to explore the conditions by which both agrobiodiversity and conventional input intensification may increase through optimal adjustments of input use in biodiversity poor agroecosystems. The model shows that this result can arise in quite general circumstances where there is (1) an agricultural production technology that allows a positive relationship between ecological integrity of a given agricultural area and agricultural productivity in that area, and (2) decision maker preferences that recognise this positive relationship and generate resource allocation decisions that support it. While increase...

The economics of agrobiodiversity conservation for food security under climate change AgEcon
Pascual, Unai; Narloch, Ulf; Nordhagen, Stella; Drucker, Adam G..
Subsistence-based and natural resource-dependent societies are especially vulnerable to climate change. In such contexts, food security needs to be strengthened by investing in the adaptability of food systems. This paper looks into the role of agrobiodiversity conservation for food security in the face of climate change. It identifies agrobiodiversity as a key public good that delivers necessary services for human wellbeing. We argue that the public values provided by agrobiodiversity conservation need to be demonstrated and captured. We offer an economic perspective of this challenge and highlight ways of capturing at least a subset of the public values of agrobiodiversity to help adapt to and reduce the vulnerability of subsistence based economies to...
