Utilization of agricultural and forestry resources in Central Guatemalan Highlands: a case study

Journal Articles & Books
November, 2011
Guatemala

This paper analyses some key findings emerged in the study of the Mayan community of S. Jos Sinach, located in the Guatemalan Highlands. The research highlights how colonial and post-colonial legislation influences the actual land tenure and hampers the development of the community. Little land ownership together with high demographic growth lead to insufficient crop production. As a consequence, human pressure on S. Jos forest and seasonal migration to sugar cane plantations of the Pacific Coast is carried out by householders in order to ensure subsistence to their families.

Interdependence in rainwater management technologies: an analysis of rainwater management adoption in the Blue Nile Basin

Ethiopia

In the Blue Nile Basin of Ethiopian highlands, rainfall distribution is extremely uneven both spatially and temporally. Drought frequently results in crop failure, while high rainfall intensities result in low infiltration and high runoff causing soil erosion and land degradation. These combined factors contribute to low agricultural productivity and high levels of food insecurity. Poor land management practices coupled with lack of effective rainwater management strategies aggravate the situation.

Soil and carbon losses from five different land management areas under simulated rainfall

Journal Articles & Books
December, 2009

The loss of soil and carbon (C) from erosional processes is of greater importance to agricultural productivity and sustainable resource management. Land management practices influence structural properties of soil aggregates, its size and stability, and the stabilization effect of soil organic carbon (SOC), and other cementing agents. Water erosion affects all these properties and consequently decreases productivity of land. Thus, relative significance of loss of soil and C from dry and wet aggregates was studied from soil sampled from the North Appalachian Experimental Watersheds (NAWEP).

Estimated soil organic carbon change due to agricultural land management modifications in a semiarid cereal-growing region in Central Spain

Spain

Maintaining or increasing soil organic carbon (SOC) in agricultural lands is important for soil productivity, restoration and could potentially be a factor in reducing carbon emissions. In order to implement best practices for maintaining productivity and increasing SOC, there is a need for understanding how management changes may alter SOC levels. This applied study presents a methodology to assess and predict SOC levels to better understand effects modification to land management can have in semiarid central Spain. Results show extensification using longer-term pasture rotations (e.g.

Some observations about man-made features on natural terrain in Hong Kong

Hong Kong

Much of Hong Kong is currently undeveloped and consists of vegetated, relatively steep hillsides, which are considered to be natural terrain. However, in many of these areas there is evidence in old aerial photographs of man-made features, which for the last 30–40 years or so have been hidden by dense vegetation. Before the 1970s the vegetation was considerably less dense than today and much of the ground surface was bare and clearly apparent.

role of federal agencies in the application of scientific knowledge

Journal Articles & Books
December, 2010

Environmental and ecological research has long been characterized as operating along a continuum, with “basic” – representing “investigator‐initiated” research – at one end and “applied” – representing “mission‐initiated” research – at the other. While federal agency science programs ideally occupy points along this continuum, the resulting science has not always been relevant to solving environmental problems.

Operationalizing ecosystem services for the mitigation of soil threats: A proposed framework

Journal Articles & Books

Europe

Despite numerous research efforts over the last decades, integrating the concept of ecosystem services into land management decision-making continues to pose considerable challenges. Researchers have developed many different frameworks to operationalize the concept, but these are often specific to a certain issue and each has their own definitions and understandings of particular terms.

Response of orthopteran diversity to abandonment of semi-natural meadows

Journal Articles & Books
December, 2009

The response of orthopteran communities to abandonment of extensively managed hay meadows was investigated in an Alpine region. Fifty-five sites in four different successional stages were sampled: (i) mown meadows, (ii) young abandoned meadows, (iii) old abandoned meadows, and (iv) young forests. Mown meadows and young abandoned meadows (3-5 years since the last cut) had the highest, young forests the lowest mean number of orthopteran species.
