Agricultural Subsidies and Forest Pressure in Malawi's Miombo Woodlands AgEcon
Fisher, Monica G.; Shively, Gerald E..
This paper examines impacts of an agricultural subsidy program on forest pressure in Malawi. Using household survey data, we measure the effect on forest product marketing and on forest clearing of Malawi's Starter Pack Scheme (SPS). Regression results show households receiving a free packet of hybrid maize seed and chemical fertilizer (a "starter pack") had lower levels of commercial forest extraction than nonrecipient households. In addition, no measurable effect of starter pack receipt is found on forest clearing decisions, suggesting the program raised agricultural output without encouraging agricultural expansion. Findings thus indicate potential modest improvement in forest condition due to the SPS.

Shorter Fallow Cycles Affect the Availability of Noncrop Plant Resources in a Shifting Cultivation System Ecology and Society
Dalle, Sarah Paule; Department of Plant Science, Macdonald Campus of McGill University; sarah.dalle@mail.mcgill.ca; de Blois, Sylvie; Department of Plant Science and McGill School of Environment, McGill University; sylvie.deblois@mcgill.ca.
Shifting cultivation systems, one of the most widely distributed forms of agriculture in the tropics, provide not only crops of cultural significance, but also medicinal, edible, ritual, fuel, and forage resources, which contribute to the livelihoods, health, and cultural identity of local people. In many regions across the globe, shifting cultivation systems are undergoing important changes, one of the most pervasive being a shortening of the fallow cycle. Although there has been much attention drawn to declines in crop yields in conjunction with reductions in fallow times, little if any research has focused on the dynamics of noncrop plant resources. In this paper, we use a data set of 26 fields of the same age, i.e., ~1.5 yr, but differing in the...

Sistema de organização do conhecimento sobre intensificação agropecuária: agregando valor às redes de conhecimento da Embrapa. Repositório Alice
PIEROZZI JUNIOR, I.; OLIVEIRA, L. H. M. de; ALENCAR, M. de C. F.; ALMEIDA, G. M. de B..
O presente trabalho relata a experiência desenvolvimento e aplicação, no âmbito de um projeto de pesquisa, de um modelo de organização e representação do conhecimento sobre os processos de intensificação agropecuária, contextualizados por observações empíricas em regiões produtoras de commodities agrícolas no Brasil. Tal iniciativa partiu da preocupação de oferecer soluções adequadas e oportunas para sistematização, organização e disseminação do conhecimento sobre esse assunto, visando facilitar o seu compartilhamento pela comunidade científica e atores do setor agropecuário.

The hedgification of maizescapes? Scalability and multifunctionality of Jatropha curcas hedges in a mixed farming landscape in Zambia Ecology and Society
van der Horst, Dan; University of Edinburgh; dan.vanderhorst@ed.ac.uk; Vermeylen, Saskia; Lancaster University; s.vermeylen@lancaster.ac.uk; Kuntashula, Elias; University of Zambia; ekuntashula@unza.zm.
We argue that reading the local agricultural landscape is a prerequisite to understanding the plausible local impacts of external drivers for change, such as the introduction of new crops and technologies. Initially driven by a desire to understand the potential for small-scale farmers to produce jatropha biodiesel in a sustainable way, we started to examine how farmers related to trees in different parts of the agricultural landscape. This provided us with insights into small-scale processes of land enclosure and conversion, which indicate that agricultural intensification is taking place. We learned that although the landscape could in theory accommodate a lot of jatropha hedges around existing (maize dominated) arable land, farmers were only creating...

The impact of the Single Farm Payments on the Expenditure on Fertilizers and crop protection inputs: a comparative study of the Italian agriculture AgEcon
Vollaro, Michele.
The Health Check (HC) of the European Common Agricultural Policy in 2003 sped up the process of policy reforms toward decoupled payments in order to urge agricultural production to respond to market signals. However, since decoupled payments could generate “coupled” effects on production, it remains questionable how single farm payment (SFP) alters agricultural intensification. Therefore, through a comparative statistical analysis applied on Italian FADN regional data, this paper aims at evaluating whether the HC reform had positive impacts on the aggregate expenditure on fertilizers and crop production inputs. From the results, it is observed that the expansion of profitable crops like vegetables, flowers and vineyards, along with the receipt of SFP...

Towards a universal sampling protocol for soil biotas in the humid tropics. Repositório Alice
BIGNELL D. E..
This paper reviews the methods for the inventory of below-ground biotas in the humid tropics, to document the (hypothesized) loss of soil biodiversity associated with deforestation and agricultural intensification at forest margins. The biotas were grouped into eight categories, each of which corresponded to a major functional group considered important or essential to soil function. An accurate inventory of soil organisms can assist in ecosystem management and help sustain agricultural production. The advantages and disadvantages of transect-based and grid-based sampling methods are discussed, illustrated by published protocols ranging from the original "TSBF transect", through versions developed for the alternatives to Slash-and-Burn Project (ASB) to the...
