Abstract Forest plantations have increased rapidly in the last three decades, to a large extent due to direct and indirect financial incentives. At the farm level, forestry incentives can affect the investment decisions of small forest landowners and bring socioeconomic externalities or unintended effects associated with farm management. The purpose of this study is to assess the ex post impacts of a forestry subsidy on land use changes and off-farm income experienced by Chilean small forest lan...

This paper examines the effectiveness of intrinsic and extrinsic motivations on the adoption intensity of sustainable agricultural practices (SAPs) among annual crop farmers in Chile. We use the farmers’ attitude towards SAPs as a proxy of intrinsic motivation, while extrinsic motivation is represented by an economic incentive to promote the use of SAPs. The policy program we studied is administered by the Chilean Ministry of Agriculture under the name System of Incentives for the Agro-Environme...

The world’s five Mediterranean-climate regions (MCRs) share unique climatic regimes of mild, wet winters and warm and dry summers. Agriculture in these regions is threatened by increases in the occurrence of drought and high temperature events associated with climate change (CC). In this review we analyze what would be the effects of CC on crops (including orchards and vineyards), how crops and cropping and farming systems could adapt to CC, and what are the social and economic impacts, as well ...

The objective of this paper is to assess the effect of long-term participation in an extension program on peri-urban family farming earnings. For this purpose, a survey of a sample of 156 participants in the Local Development Program (PRODESAL) of the Chilean National Institute for Agricultural Development (INDAP) was conducted in the Metropolitan Region of Santiago. Half of the respondents were long-term participants with at least four yrs in the program, and the rest of the farmers were one-yr...

This article applies a Logit regression model to examine the factors that contribute to the adoption of irrigation scheduling by small-scale farmers in Central Chile. Socio-economic and productive information was collected from a random sample of 112 small-scale, irrigated farms during the 2010/2011 season. One important feature of this research is the specific extension and training in irrigation scheduling received by some of the farmers. Irrigation scheduling consists of estimating the optimu...

This article examines the influence of intrinsic and extrinsic motivations, as well as the interplay between the two, on the adoption intensity of soil conservation agriculture (SCA). It seeks to understand the drivers of SCA among annual crop farmers using three conservation practices subject to be financed by an economic incentive for degraded soils in Chile; namely conservation tillage, stubble incorporation, and use of organic manure. The incentive to conservation represents an extrinsic mot...

This study analyses technical efficiency (TE) levels among small-scale raspberry producers in Central Chile. Special attention is given in to investigate the impact of the marketing channel used by the farmers on their technical performance. The data used in this study were obtained from a farm-level survey of 139 small-scale raspberry farmers. A stochastic production frontier model was used to evaluate the association between TE, extension, training and farmers’ decisions to sell their producti...

Adaptation to climate change is imperative to sustain and promote agricultural productivity growth, and site-specific empirical evidence is needed to facilitate policy making. Therefore, this study analyses the impact of climate change adaptation on productivity for annual crops in Central Chile using a stochastic production frontier approach. The data come from a random sample of 265 farms located in four municipalities with different agro-climatic conditions. To measure climate change adaptati...

Recently, social capital has gained importance in explaining technology adoption decisions by farmers. In this paper, we examine the impact of social capital on the adoption of irrigation technology and irrigation scheduling among wine producers in Central Chile. We propose three hypotheses: that trust and networks affect positively the adoption of both technologies (H1 and H2) and that trust is positively related to networks (H3). First, we identify seven different components of social capital:...
