This study used the C4.5 data mining algorithm to model farmers’ crop choice in two watersheds in Thailand. Previous attempts in the Integrated Water Resource Assessment and Management Project to model farmers’ crop choice produced large sets of decision rules. In order to produce simplified models of farmers’ crop choice, data mining operations were applied for each soil series in the study ar...

We present a bio-economic model that accounts for the effects of water and nitrogen use on the first three moments of profit margin distributions in Swiss maize production. We thus also account for downside risks in farmers’ decision making processes, which extents currently used bio-economic modeling approaches that address agricultural water use. We find that because irrigation reduces the ne...

In this paper we examine the role played by environmental externalities in shaping the dynamics of an economy with two sectors (a farming sector and an industrial one), free inter-sectoral labor mobility and heterogeneous agents (workers/farmers and industrial entrepreneurs). We find that, in the presence of the environmental pressure of the economic activity of the industrial sector, the stabi...

— This paper links changing global coffee markets to opportunities and vulnerabilities for sustaining small-scale farmer livelihoods in northern Nicaragua. Changing governance structures, corporate concentration, oversupply, interchangeable commodity grade beans, and low farm gate prices characterize the crisis in conventional coffee markets. In contrast, certified Fair Trade and organic are tw...

■ Abstract The consequences of the invention of DNA-based molecular techniques and their application to agriculture have been pervasive. This review examines the key consequences for farmers and the public. These include widespread commercial applications of agricultural biotechnology in a limited number of countries, a large private-sector investment in biotechnology research, significant econ...

Please c are Cha Summary. — Market trends are becoming prominent forces shaping local landscapes. The increasing demand for high-quality and sustainable coffees is driving land-use decisions among Colombian farmers. A value chain analysis shows that farmers who sell to differentiated markets significantly captured a larger portion of the value added and faced lower volatility than mainstream pr...

Understanding the formation mechanism of farmers’ farmland value expectations not only helps to evaluate land resource allocation behaviors, but also enables government create better policies that can effectively guide and manage expectations. Based on cross-sectional data from 2015 China Household Finance Survey (CHFS) rural residents, we used quantitative analysis models identify effect expro...

Ecosystem management requires the explicit treatment of interactions between humans and ecosystems. An exploratory model for integrating social and ecological dynamics was introduced to study ecosystem management strategies. This paper focuses on the management of lake eutrophication. The model was developed to include the dynamics of the lake, the behaviour of agents using phosphorus for agric...
