functional evaluation of three indicator sets for assessing soil quality

Journal Articles & Books
december, 2013
Brazil

Efforts to define and quantify soil quality are not new, but establishing consensus about a set of standardized indicators remains difficult. Also, the view of land managers is usually not taken into account when evaluating various sets of indicators. Our objective was to compare, in functional terms, soil quality assessments based on 29 indicators, a subset with 8 of those indicators, and 4 indicators selected independently by farmers, based on their perceptions of soil quality.

Farmers’ livelihood assets and adoption of sustainable land management practices in north-western highlands of Ethiopia

Journal Articles & Books
december, 2013
Ethiopia

In Ethiopia, farmers’ adoption and continued use of introduced land management technologies have not been widespread to reduce soil erosion and soil fertility depletion to an acceptable level. An important set of factors in farmers’ use of improved agricultural technologies is generally known to be their possession of livelihood assets. This study examines the influence of ownership of livelihood assets in farmers’ decisions to use cattle manure as land improvement technology, which is currently being promoted by Ethiopia’s agricultural extension system.

development of soil and water conservation policies and practices in five selected countries from 1960 to 2010

Since the 1930s there has been worldwide concern about the effects and impacts of land degradation. After the problems experienced in the Dust Bowl in the USA, much attention was paid to soil and water conservation in both developed and developing countries. Initially Governments stimulated the establishment of physical control measures, such as terraces, check dams and reforestation. This was achieved through top-down regulations, and Forestry Departments were often in charge of the implementation.

arithmetic method to determine the most suitable planting dates for vegetables

Saudi Arabia

Optimum crop yield is greatly affected by proper planting and sowing times. The objective of this research was to develop an algorithm that uses the heat unit concept to determine the most suitable planting times for vegetable crops. The developed algorithm was programmed in a database environment with sample climatic data for the Kingdom of Saudi Arabia. The model was tested by validation (comparison to experts’ estimations), verification (statistical comparison to formal published data), and evaluation (by professionals, landowners, and farmers).

Livestock and the rangeland commons in South Africa's land and agrarian reform

Southern Africa

Land and agrarian reform has the potential to expand South Africa's rangeland commons and enhance their contribution to the livelihoods of the rural poor, yet to a large extent this has been an opportunity missed. Shifting policy agendas have prioritised private land rights and commercial land uses, seeking to dismantle the racial divide between the white commercial farming areas and the ex-Bantustans by allocating former white farms to black farmers. These agendas and planning models reflect class and gender bias and a poor understanding of common property.

Wasted waste—Disappearing reuse at the peri-urban interface

Safe and sustainable management of waste presents a major challenge in cities in the Global South. For decades farmers in the peri-urban interface (PUI) have used biodegradable components of urban waste as inputs into their farming practices. Evidence from Kano, Nigeria; Kumasi, Ghana; Hubli-Dharwad and Kolkata, India reveals in rare detail how urban waste reuse plays an important role in the livelihood strategies of lower-income families nd while waste farming also contributes significantly to urban food security.

Hydrological and meteorological extremes derived from taxation records: the estates of Brtnice, Třebíč and Velké Meziříčí, 1706–1849

This paper addresses the hydrological and meteorological extremes that may be deduced from the taxation records of the estates of Brtnice, Třebíč and Velké Meziříčí, all in the Moravian-Bohemian Highlands of the Czech Republic, for the years 1706–1849. At that time, damage to agricultural crops constituted grounds for tax remission for individual farmers and landowners.

Improving Farming Practices in Municipality of Gazi, Crete, Greece

Journal Articles & Books

Greece

A soil survey and mapping program financed by the municipality of Gazi located on the north–central part of Crete was carried out. The studied area is characterized by a moist meso-Mediterranean climate and different degrees of land degradation from human activities. Surface soil horizons are eroded, resulting in fertility decline for olive trees, the dominant crop. According to the U.S. Department of Agriculture classification, the soils at higher altitudes are classified as Entisols xerorthents and those at lower altitudes as E. xerofluvents.

survey-based exploration of land-system dynamics in an agricultural region of Northeast China

Journal Articles & Books
december, 2013

Understanding the complexity of agricultural systems requires insight into the human–environment interactions. In this paper we used survey data to analyze land system change and its relation to farmer’s attitudes in a typical agricultural region of Northeast China, focusing on land tenure, crop choice and intensification. Our survey shows that land transfer was fairly common across the study area: average farmland acreage per household almost doubled from 1.3ha by early 1980s to 2.6ha by early 2010s, especially due to urban migration of farmers.

Monitoring changes in pastoral resources in eastern Sudan: A synthesis of remote sensing and local knowledge

Sudan

The pastoral resources in eastern Sudan are changing under the combined impact of increasing anthropogenic activities such as clearance of natural vegetation and the effect of state policies that favour crop farming against pastoralism. Remotely sensed data are used to detect spatial and temporal changes from 1979 to 2009 in the land use/land cover (LULC) across three study sites. Areas of natural vegetation have been reduced from 26.1% in 1979 to 12.6% in 1999 and further to 9.4% in 2007. The majority of this reduction went into agricultural land.

Quantifying rural livelihood strategies in developing countries using an activity choice approach

Mozambique

This article uses a quantitative activity choice approach, based on identification of activity variables and application of latent class cluster analysis, to identify five major rural livelihood strategies pursued by households (n= 576) in Bolivia, Nepal, and Mozambique. Income sources and welfare outcomes are compared across strategies and household differences in asset holdings are analyzed using multinomial logit regression.

Conservation Practices for Climate Change Adaptation

United States of America

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.
