Farmers’ assessment of soil quality in rice production systems

Journal Articles & Books
Diciembre, 2011
Brasil

In the recent past there has been increasing recognition that local knowledge of farmers can yield insight into soil quality. With regard to constraints and possibilities for the production of irrigated rice in the south of Brazil there is no documentation on local soil knowledge. The goals of this study were to answer the following questions: (1) Which soil quality perceptions do rice farmers have? (2) Which soil quality indicators are most important to them?

Climate change perceptions and adaptive responses of smallholder farmers in central highlands of Ethiopia

Journal Articles & Books
Diciembre, 2012
Etiopía

This paper presents an assessment of smallholder farmers’ perceptions of climate change, its impacts on agricultural production and adaptive responses in the central highlands of Ethiopia. The findings show that increased temperature and decreased rainfall are widely held perceptions; all respondents stated that they had observed increase in temperature and decrease in annual and seasonal rainfall amounts.

Game changers for irrigated agriculture—do the right incentives exist?

África

Game changers to achieve sustainable intensification of agriculture are possible in the irrigation sector and they focus mainly on getting more with less. There is, however, still a long way to go to replicate, adapt and develop approaches to take such ideas to scale and increase productivity within existing agricultural water management contexts.

Towards a standardised procedure for determining the potentially mineralisable nitrogen of soil

Journal Articles & Books
Diciembre, 2003

Reliable techniques for predicting N mineralisation dynamics in soil are required for sustainable management of land resources. The concept of potentially mineralisable N (N ₀) and its determination procedures were re-appraised in this study. Leaching soil before incubation removed considerable amounts of soluble organic N. But the leached soils had higher rates of net N mineralisation than the unleached controls during a subsequent 2-week incubation, suggesting that using the total amount of leached- (organic + inorganic) N for calculating N ₀ may not be warranted.

Analysis of Rural Landscape and Land Fragmentation Through GIS in the Gjocaj Commune, Albania

Albania

After the downfall of the socialist economic system in 1990, Albania underwent an agriculture reform in 1992. After the reform execution, all agricultural land was redistributed among village residents. The subsequent land segmentation lead to extreme agriculture production implications.Gjocaj Commune is located in the centre of Albania at the Peqin District part of the Elbasan Region, which is a typical agricultural area, very close to Tirana and not far from the Adriatic seashore.

Gender mainstreaming and participative planning for sustainable land management

Journal Articles & Books
Diciembre, 2011

This contribution outlines the potential of the category of gender in critical analyses of land use policy and the perspectives it offers for the development of conceptual strategies for sustainable land management. It illustrates gender mainstreaming in urban development approaches, thus showing the potential for enhancing the quality of planning and the reduction of land consumption. The paper goes on to discuss the potential for extended and differentiated communication and participation within participative planning support systems.

Bamboo based agroforestry systems in Kerala, India: performance of turmeric (Curcuma longa L.) in the subcanopy of differentially spaced seven year-old bamboo stand

India

Bamboo-based agroforestry is a promising option for sustainable land management in India. Optimal management of bamboo-based mixed species production systems, however, requires an understanding of bamboo spacing, root activity and distribution of bamboo roots, and the soil nutrient capital of the site. We examined the performance of turmeric as an understorey crop in 7-year old bamboo (Dendrocalamus strictus (Roxb.) Nees) stands of varying spacing treatments (4 × 4, 6 × 6, 8 × 8, 10 × 10 and 12 × 12 m) at Kerala Agricultural University Campus, Thrissur, Kerala, India.

Conservation Practices for Climate Change Adaptation

Estados Unidos de América

The threat of climate change is a great challenge to sustainable land management (USDA-NRCS, 2010a). Several publications have reported that over the last few decades, rainfall intensities have increased in many parts of the world, including in the United States. Without good, productive soils and the ecosystem services provided by them, the survival of our species will be in jeopardy. The future changes in climate that will drive erosion processes will significantly impact soil erosion rates, with higher projected erosion rates for the United States.

Land use policies and practices for reducing vulnerability in rural Tajikistan

Journal Articles & Books
Diciembre, 2011
Tayikistán

Tajikistan, with 93% of its surface area taken up by mountains and 65% of its labor forceemployed in agriculture, is judged to be highly vulnerable to risks, including climate changerisks and food insecurity risks. The article examines a set of land use policies and practices thatcan be used to mitigate the vulnerability of Tajikistan’s large rural population, primarily byincreasing family incomes. Empirical evidence from Tajikistan and other CIS countries suggeststhat families with more land and higher commercialization earn higher incomes and achievehigher well-being.

Forested Landscapes Promote Richness and Abundance of Native Bees (Hymenoptera: Apoidea: Anthophila) in Wisconsin Apple Orchards

Journal Articles & Books
Diciembre, 2011

Wild bees provide vital pollination services for many native and agricultural plant species, yet the landscape conditions needed to support wild bee populations are not well understood or appreciated. We assessed the influence of landscape composition on bee abundance and species richness in apple (Malm spp.) orchards of northeastern Wisconsin during the spring flowering period. A diverse community of bee species occurs in these apple orchards, dominated by wild bees in the families Andrenidae and Halictidae and the honey bee, Apis mellifera L.

Farmers’ Visions on Soils: A Case Study among Agroecological and Conventional Smallholders in Minas Gerais, Brazil

Journal Articles & Books
Diciembre, 2012
Brasil

Purpose: Why do farmers not take better care of their soils? This article aims to give insight into how farmers look at soil quality management. Design/methodology/approach: It analyses diverse land management practices and visions on soils and soil quality of ten agroecological and 14 conventional smallholder farmers in Araponga, Minas Gerais, Brazil. As agroecological farming (that is, managing soils with minimum use of external inputs) requires more complex knowledge, it is assumed that agroecological farmers would be more knowledgeable on soils compared to conventional farmers.

spatial nexus between population growth and land degradation in a dry Mediterranean region: a rapidly changing pattern?

A better understanding of the spatial linkage between the distribution of land vulnerable to degradation and long-term population growth may contribute to sustainable land management of dry regions. Such a nexus has received increasing attention among politicians and local stakeholders, as its complex outcomes depend on mutual interactions between socioeconomic and biophysical factors. This is particularly true in southern Europe, where important processes of land degradation (LD) have been observed in recent years.
