Knowledge and Adoption of Organic Agriculture: Diffusion Over Time Among Andalusian Olive Farmers AgEcon
Lopez, Carlos Parra; Calatrava-Requena, Javier; Gimenez, Tomas De Haro.
The objective is to analyse the diffusion over time process of the knowledge and adoption of a sustainable technological innovation -organic agriculture- in the South of Spain -Andalusia region- and for a crop of paramount importance there -olive- within the framework of the Diffusion of Innovations Theory. Results show that diffusion is essentially due to an autonomous "contagion" among olive growers with a little external intervention. In many regions, particularly in low yield conditions, adoption of organic farming has come to an standstill, demonstrating the need to strengthen or modify the mechanisms of diffusion commonly used up to this time.

Main problems of agriculture and rural areas in Poland in the period of transformation and integration with European Union AgEcon
Zegar, Jozef St.; Florianczyk, Zbigniew.
Problems currently observed in Polish agriculture have different origins. Some of them have an historical background, while others are related to systemic transformation and forthcoming accession to the European Union. Most of the problems are common for all the candidate countries and most of them are also observed in the developed economies. Identification of these problems is the main purpose of this article. Special attention is paid to natural, human and capital resources available in rural areas. Possible development paths are pointed out. The article also covers most of the opportunities that may help overcome rural development problems in Poland in the wake of forthcoming accession, and their limitations.

Sustainable Development and Intergenerational Equity: Issues Relevant to India and Globally AgEcon
Tisdell, Clement A..
As outlined, recurring concerns have surfaced since the 1700s that economic growth may prove to be unsustainable. These concerns have been expressed again and have intensified in recent decades but their foundation differs from that of Malthus. The rapid economic growth of China and India have added to these worries. Recent discussions by economists of the desirability of achieving sustainable economic development have mainly focused on measures to attain intergenerational equity in resource use and the dominant view is that each succeeding generation should be at least as well-off as its predecessor. While this is said to be an implication of Rawls’ principle of justice, this dominant rule does not fully reflect Rawls’ principle and it also can violate...

Comparative Costs and Conservation Policies for the Survival of the Oranutan and Other Species: Includes an Example AgEcon
Tisdell, Clement A.; Swarna Nantha, Hemanath.
The extent to which conservation is feasible is constrained by budgets and the financial sacrifice stakeholders are willing to bear. Therefore a possible objective for conserving a species is to minimise the cost of achieving that stated aim. For example, if a minimum viable population (MVP) of a species is to be conserved, the size and type of habitats reserved for this could be selected to minimise cost. This requires consideration of the comparative (relative) opportunity costs of reserving different land types for conservation. A general model is developed to demonstrate this and is applied to the case of the orangutan. In the ecological literature, recommendations for reserving different types of land for conservation have been based on comparisons of...

Rational Expectation and Education Rewarding: The Case of Chinese Off-Farm Wage Employment AgEcon
Hou, Linke; Wang, Xiaobing; Yu, Xiaohua.
This study establishes a life-cycle model that a representative agent chooses optimal time of education to maximize his/her life earning, which implies that there may exist nonlinear relation between education and earning. Using the data of Chinese off-farm wage employment, we find that the duration of schooling years will increase by 1.7 years with 1 percent increase in rate of return to education. The empirical results also indicate that controversies about return to education might arise from model misspecification without consideration of nonlinearity and sample selection.

Biodiversity Valuation in Developing Countries: A Focus on Small Island Developing States (SIDS) AgEcon
Teelucksingh, Sonja S.; Nunes, Paulo A.L.D..
The Millennium Development Goals explicitly recognise “sustainable development” as a target. A step towards this is a greater understanding of the significant role of biodiversity in rural communities of developing countries who depend most on the ecosystem goods and services and who as a result may suffer most from its continued degradation. Understanding the input of biodiversity in developing countries to the provision of the ecosystem goods and services (EGS) that are essential to their human well-being is seen as a significant first step in sustainable development, and environmental valuation is a necessary tool for achieving this objective. However, valuing biodiversity in a developing country context can be an intricate affair. While economic...

Optimal Forest Strategies for Addressing Tradeoffs and Uncertainty in Economic Development under Old-Growth Constraints AgEcon
Krcmar, Emina; Eagle, Alison J.; van Kooten, G. Cornelis.
In Canada, governments have historically promoted economic development in rural regions by promoting exploitation of natural resources, particularly forests. Forest resources are an economic development driver in many of the more than 80% of native communities located in forest regions. But forests also provide aboriginal people with cultural and spiritual values, and non-timber forest amenities (e.g., biodiversity, wildlife harvests for meat and fur, etc.), that are incompatible with timber exploitation. Some cultural and other amenities can only be satisfied by maintaining a certain amount of timber in an old-growth state. In that case, resource constraints might be too onerous to satisfy development needs. We employ compromise programming and fuzzy...

Effectiveness of Integrated Pest Management Dissemination Techniques: A Case Study of Potato Farmers in Carchi, Ecuador AgEcon
Mauceri, Maria; Alwang, Jeffrey Roger; Norton, George W.; Barrera, Victor.
Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields. Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability. Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed. We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission. Field days and pamphlets have strong impacts on adoption, especially considering their low costs. FFS are effective, but expensive. Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high...

REGIONAL DEVELOPMENT OPTIONS ON A LOCAL SCALE BEYOND 2013 – THE CASE OF CAITHNESS AND SUTHERLAND (SCOTLAND, UK) AgEcon
Bergmann, Holger; Thomson, Kenneth J..
With the latest reform of EU Structural Policy, the Highlands and Islands have been excluded from further support by Structural Funds beyond 2013, but the new Scottish Rural Development Programme has increased CAP Pillar 2 expenditures in Scotland. A modified version of a system dynamics model constructed for an EU-wide case-study project (TOP-MARD) was used to simulate the effects of these and other policy changes in Caithness and Sutherland (C&S), a remote rural area in Northern Scotland. Several alternative modelling scenarios were developed, mostly relating to reconfigurations of Pillar 2 spending within the area. The modelling results, i.e. projections from 2001 to 2021, are discussed in terms of agricultural employment, regional population, and...

The Equivalence of Strict Liability and Negligence Rule: A « Trompe l'œil » Perspective AgEcon
Gerard, Mondello.
This paper analyzes the difficulties of comparing the respective effectiveness of two among the most important liability regimes in tort law: rule of negligence and strict liability. Starting from the standard Shavellian unilateral accident scheme, I show that matching up liability regime on their capacity to provide the highest level of safety is ineffective. This demonstration lies on two components. The first one gathers some results drawn from literature that introduces uncertainty. The second one takes into consideration the beliefs of agents and their aversion to ambiguity. The model applies uncertainty to the level of maximum damage. This demonstration reinforces the previous result. Hence, both regimes apply on specific tort question and comparing...

Assessing Domestic Demand for Organic and ‘Locally Grown' Produce on An ‘Organic Island': Dominica's Dilemma AgEcon
Boys, Kathryn A.; Willis, David B.; George, Seraphine; Hammig, Michael D..
The economy of Dominica faces a unique set of challenges. As with many other Caribbean nations, Dominica has historically been dependent upon agriculture. Over the past several hundred years, the island's economy has been largely supported through the concentrated mono-cropping of a variety of export-oriented crops including coffee, limes, vanilla, and bananas (FAVACA, 2008). Today, approximately 45% of Dominica's labor force is employed in the agricultural sector (FAVACA, 2008). While neighboring countries have economically benefited from tourism, due to its lack of white sand beaches, Dominica is not a typical tourist destination. Taking advantage of its landscape, rainforests, and diversity of natural wildlife, in an effort to diversify its economy...

Organic Apple Production in Washington State: An Input-Output Analysis AgEcon
Mon, Pon Nya; Holland, David W..
This paper provides an Input-Output (I/O) based economic impact analysis for organic apple production in Washington State. The intent is to compare the economic “ripple” effect of organic production with conventional production. The analysis is presented in two scenarios: first we compare the economic impact of organic versus conventional apple production for a l demand increase of one million US$ as measured in sales. The second analysis looks at the economic impact of organic and conventional apple production in terms of given unit of land (405 hectares of production). Both state-wide output (sales) and employment (jobs) impacts are estimated under each scenario. Results are presented in terms of direct, indirect, and induced economic impact. Organic...

What Explains the Incidence of the Use of a Common Sediment Control on Lots with Houses Under Construction? AgEcon
Templeton, Scott R.; Sessions, William T.; Haselbach, Liv M.; Campbell, Wallace A.; Hayes, John C..
To analyze compliance with one aspect of the regulation of stormwater discharge, we estimate a random-utility model of the probability that a builder uses a silt fence to control sediments on a lot with a house under construction in an urbanizing county of South Carolina. The probability increases if the builder is responsible to the subdivision’s developer or if a homeowners association exists. The probability also increases as the cost to install a silt fence decreases or the number of houses under construction per built house in a subdivision increases. The results can help county officials target inspection to improve compliance.

Equilibrium management of fisheries with altruistic overlapping generations AgEcon
Ekeland, Ivar; Karp, Larry S.; Sumaila, Ussif Rashid.
We imbed a classic fishery model, where the optimal policy follows a Most Rapid Approach Path to a steady state, into an overlapping generations setting. The current generation discounts future generations’ utility flows at a rate possibly different from the pure rate of time preference used to discount their own utility flows. The resulting model has non-constant discount rates, leading to time inconsistency. The unique Markov Perfect equilibrium to this model has a striking feature: provided that the current generation has some concern for the not-yet born, the equilibrium policy does not depend on the degree of that concern.

Effects of Global Climate Change on Nigerian Agriculture: An Empirical Analysis AgEcon
Apata, Temidayo Gabriel; Ogunyinka, A.I.; Sanusi, R.A.; Ogunwande, S..
This paper presents an empirical analysis of the effects of global warming on Nigerian agriculture and estimation of the determinants of adaptation to climate change. Data used for this study are from both secondary and primary sources. The set of secondary sources of data helped to examine the coverage of the three scenarios (1971-1980; 1981-1990 and 1991-2000). The primary data set consists of 1500 respondents’ but only 1250 cases were useful. This study analyzed determinants of farm-level climate adaptation measures using a Multinomial choice and stochastic-simulation model to investigate the effects of rapid climatic change on grain production and the human population in Nigeria. The model calculates the production, consumption and storage of grains...

The Impact of Protest Responses in Choice Experiments AgEcon
Barrio, Melina; Loureiro, Maria L..
Not much attention has been given to protest responses in choice experiments (CE). Using follow-up statements, we are able to identify protest responses and compute welfare estimates with and without the inclusion of such protest responses. We conclude that protest responses are fairly common in CE, and their analysis affects the statistical performance of the empirical models. In particular, when the sample is corrected by protests, our results come from utility consistent models. Thus, future choice experiments should consider the role of protest responses as contingent valuation studies have done.

Food Consumption for the Poor: A Supply or an Income Issue? Evidence from Less-favored Regions in Rural China AgEcon
Zhu, Jing; Hare, Denise; Zhong, Funing.
The world food crisis has brought about heated discussions on policy responses and actions to achieve future stability and security in food consumption for the poor. While many viewing it as a supply proglem and propose to cope with it by incrasing self-supply, there are also propostitions of viewing it more as an income problem. This paper has taken the experience of China into study. Being the most populous nation in the world and with rural low-income and low food consumption groups still a noticeable portion in the rural area, China has devoted strenuous efforts by utilizing various policy approaches. This paper has estimated empirically the impact of different policy measures, i.e., the predominantly used traditional policy aimed at increasing...

Multifunctional land use: is it a key factor for rural development? AgEcon
Kopeva, Diana Ilieva; Peneva, Mariya Marinova; Madjarova, Svetla Ivanova.
The sustainable development of rural areas faces nowadays the challenges of global changes. The need to adapt land and landscape use to the new social, economic and ecological demands (non-farm activities, employment in rural areas, forest and agro- related tourism, real estate pressure, etc.) requires an analysis of the land multifunctionality and of the multipurpose land management strategies. The paper aims to review the concept of land use and landscape multifunctionality and to review the role of multifunctional land use in Rural Development Policy in Bulgaria.
