Ecological succession and land use changes in a lake retreat area (Main Ethiopian Rift Valley)

Journal Articles & Books
december, 2013

In the semi-arid Main Ethiopian Rift Valley, ecological succession is related to continuous lake retreat. Human activity, through its impact on land use and cover, affects this ecological succession at various degrees. Through a remote sensing study, we explored how the drivers for land use and cover changes (LUCC) have changed over the last decades and which impact this has on ecological succession.

Impacts of Changing Climate and Climate Variability on Seed Production and Seed Industry

Agriculture is extremely sensitive to climate and weather conditions. The resilience of our crop production systems to changes in climate can be enhanced by improved understanding impacts and responses of crops to changing climates. Several countries in Asia and Africa are at the risk of losing about 280 million tons of potential cereal production as a result of climate change factor, particularly increasing temperatures and prolonged dry periods.

Connotative land degradation mapping: A knowledge-based approach to land degradation assessment

Journal Articles & Books
december, 2013
Mexico

Land degradation mapping is a problem-solving task that aims to provide information for allocating budgets and materials to counter the deterioration of land resources. Typically, it entails the implementation of a set of indicators in a GIS to appraise the severity of land degradation across a territory. Nevertheless, the selection of these indicators has proved to be challenging in practice and often this selection reflects one particular and thus limited perspective of land degradation.

Access to cryptic arthropod larvae supports the atypical winter breeding seasonality of Meyer’s Parrot (Poicephalus meyeri) throughout the African subtropics

Meyer’s Parrot Poicephalus meyeri has the widest distributional range of any African parrot. There are six subspecies distributed throughout the African subtropics, all of which manage to breed successfully during the winter dry season when few other cavity-nesting birds are actively nesting. In 2004, we recorded Meyer’s Parrots feeding on four cryptic arthropod larvae incubating inside fruits and pods in their seasonal diet. All of these were previously unknown in the diet of African parrots.

Property rights and climate change vulnerability in Turkish forest communities: a case study from Seyhan River Basin, Turkey

Turkey

Turkey is expected to experience significant climate change, including increased temperatures and desertification. As these changes affect forestry, agriculture and animal husbandry, they threaten the livelihoods of forest communities across the country. In addition, other, institutional factors such as the property regime can act in tandem with physical stressors to increase communities’ overall vulnerability to climate change.

Creating Extension Programs for Change: Forest Landowners and Climate Change Communication

United States of America

The Cooperative Extension Service in the United States can play an important role in educating forest landowners to improve forest resilience in the face of climatic uncertainty. Two focus groups in Florida informed the development of a program that was conducted in Leon County; presurveys and postsurveys and observation provided evaluation data. The Reasonable Person Model (RPM) was a helpful framework for developing the program and explaining results. Landowners desired more information in order to manage their forests in light of climate change after the program than before.

Integrating national forestry initiatives in India with international climate change policy

India

Policy initiatives in India, such as the Social Forestry Program and later the Joint Forest Management, were introduced for their co-benefits, including forest protection, employment opportunities, and added income for communities living in and around the forests. The evolution of these forest policies is critically reviewed. It is argued that India is perfectly positioned to benefit from climate change mitigation efforts, due to a rich, albeit chequered, history in forest management.

evil of sluits: A re-assessment of soil erosion in the Karoo of South Africa as portrayed in century-old sources

Deep, linear gullies are a common feature of the present landscape of the Karoo of South Africa, where they were known locally in the early twentieth century as ‘sluits’. Recent research has shown that many of these features are now stable and are no longer significant sediment sources, although they are efficient connectors in the landscape. Because most of the gully networks predate the first aerial photographs, little is known in the scientific literature about the timing of their formation.

phylogenetic network of wild Ussurian pears (Pyrus ussuriensis Maxim.) in China revealed by hypervariable regions of chloroplast DNA

In order to understand the genetic diversity of wild Ussurian pears in China, chloroplast DNA (cpDNA) of 186 wild accessions from 12 populations in Inner Mongolia, Heilongjiang and Jilin Provinces and 51 Chinese and European pear cultivars including Pyrus ussuriensis, Pyrus pyrifolia, Pyrus bretschneideri, Pyrus sinkiangensis and Pyrus communis were investigated. Each accession was classified into one of three types (types A, B and C) based on two large deletions in the hypervariable regions between the accD–psaI and rps16–trnQ genes.

Conversion of Communal Grazing Lands into Exclosures Restored Soil Properties in the Semi-Arid Lowlands of Northern Ethiopia

Ethiopia

In the semi-arid tropics, communal grazing lands provide a livelihood for millions of people. However, it is highly threatened by overgrazing and continuous land degradation and, as a result, proper management is important to improve the livelihood of the people. This study investigated the effectiveness of exclosures established on communal grazing lands to restore soil properties and identified the relationship among soil properties, site and vegetation characteristics, and exclosure age.

Differences in Soil Properties Between Irrigation and Cropping Sequences in the Thar Desert of India

Watering is known to convert deserts into oases. However, information on how irrigation brings changes in physical and chemical properties of soils in a desert biome is not yet known, though pertinent to land use planning. This study reports influence of irrigation and cropping sequence on physico-chemical properties of soils in the Thar Desert, Rajasthan, India.

The aim of the study was to analyze a participation process for the implementation of a sustainable land management plan in the Urdaibai biosphere reserve in northern Spain. We have analyzed the forecasted changes that would result from the implementation of the participatory process, including a quantitative evaluation of actions needed to achieve the desired outcome. We integrated participatory methods with quantitative analysis, which has allowed us to successfully identify and prioritize the proposed actions.
