Extractivisms, existences and extinctions -- The political economy of existences and extractivisms -- Four key questions for the study of existences : the agroextractivist monocultures in Mato Grosso -- Conclusions: Global extractivisms, the world-ecology and existential redistributions.

Specialization in agricultural systems leads to trade-offs between economic gains and ecosystem functions. Economic gains can be maximized when production activities are specialized at increasingly broader scales (from the household to the village, region or above), particularly when markets for...

This paper deals with the processes of the industrial proportions formation at agricultural enterprises. Trends in industrial structure have been considered. Advantages of development intersectoral integration in the agricultural sector of economy have been listed. Peculiarities of the economic...

Modern trends in the development of integrated production have been analyzed. Basic parameters of the integrated units activity have been investigated by the example of agricultural enterprises in Zhytomyr region. Strategic development directions of the agricultural economy sector have been...

Power based on biomass, in particular biogas, is increasing, with a concomitant increase in the need for energy crop production. The objective of this study was to determine the profitability of biogas substrate production on a marginal site in southwestern Germany. The effects of crop rotation...

An issue when seeking to identify rotation choice is persistence in yield-enhancement and input-saving carry-over effects. Focusing on carry-over length and the monoculture decision, we use quasi-convexity of choice functions to develop price-independent and price-dependent principles concerning...

A study was undertaken to assess the growth performance of brackishwater tiger shrimp, Penaeus monodon under monoculture in a hardwater seasonal pond in Tamil Nadu, India. A production of 209 kg/ha/110 days was attained at a low stocking density of 1.5/m2.

We gathered survey data from a random sample of 200 farmer adopters and 59 nonadopters of rice interplanting in Yunnan Province, China in 2000. The data were used to analyze the effect of interplanting on technical efficiency of rice production and to identify the sources of inefficiency, using...

Resource-based models of species competition predict that when species compete for a limiting resource in a homogeneous habitat, then the equilibrium outcome is a monoculture with the species characterised by the lowest resource requirement outcompeting all the rest. We derive harvesting rules...

This paper deals with some major economic issues concerning the Pacific plant kava, known in Fiji as yaqona. The plant is the source of the cerebral depressant beverage found throughout many of the Pacific Islands, which besides its daily use plays an important ceremonial and social role in the...

Using a Social Accounting Matrix analyses five policy options for land conservation such as reduction of peanut monoculture, internal and international migration, regional development, reforestation and land tenure reform.
