Determinants of farmers' perception of land degradation and adoption of soil conservation technologies among rice farmers in Osun-State, Nigeria

Journal Articles & Books
Dezembro, 2006
Nigéria

The study investigated farmers' perception of land degradation, and adoption of soil conservation practices using a two-stage decision making process. The data for the study were collected with the aid of structured questionnaire and analyzed with descriptive analysis and simultaneous probit model. The results show erosion as the major cause of land degradation and 69% of the farmers experienced a low level of crop loss to land degradation. Majority of the farmers (80%) prefer fertilizer application as a conservation method.

Assessment of the cover changes and the soil loss potential in European forestland: First approach to derive indicators to capture the ecological impacts on soil-related forest ecosystems

Europa

The Member States of the European Union have committed to the maintenance and protection of forest lands. More precisely, the Member States aim to ensure the sustainable development and management of the EU's forests. For 2013, Eurostat's statistics about primary and secondary wood products in the European forest land (65% thereof privately owned) estimate a roundwood production of 435 millionm3 in total. Harmonised information, i.e., spatially and temporarily differentiated, on forestry and wood harvesting activities in the European forests are missing however.

Integrative approach for landscape-based graph connectivity analysis: a case study with the common frog (Rana temporaria) in human-dominated landscapes

Journal Articles & Books
Dezembro, 2012

Graph-based analysis is a promising approach for analyzing the functional and structural connectivity of landscapes. In human-shaped landscapes, species have become vulnerable to land degradation and connectivity loss between habitat patches. Movement across the landscape is a key process for species survival that needs to be further investigated for heterogeneous human-dominated landscapes.

Methods and applications for ecological vulnerability evaluation in a hyper-arid oasis: a case study of the Turpan Oasis, China

China

The Turpan Oasis is a typical fragile environment that lies in an arid region of eastern Xinjiang and is affected by natural conditions and human activities. The severity of the land degradation and desertification in this area is increasing; therefore, ecological vulnerability evaluations are important for environmental management of the region. In this study, theories and methods of evaluating ecological vulnerability and the typical characteristics of ecological vulnerability were summarized.

Adaptive Ecosocial System Sustainability Enhancement in Sub-Saharan Africa

A conceptual framework is developed and used for improving the livelihood of Sub-Saharan communities faced with multiple stresses resulting from adverse environments, vector-transmitted diseases, and limited food. Ecosocial systems are the units for management. The accumulation of ecological, economic, and social capital is the objective of management, the reduction of maintenance costs is the key strategy, and technologies must satisfy ecological, economic, and social criteria.

Land Degradation Analysis on Coastal Area of Ampara District

Outubro, 2013
Sri Lanka

The island of Sri Lanka is free from serious natural hazards such as volcanic activity and earthquakes resulting from climatic extremes, but there are impacts of many natural disasters, such as landslides, floods and droughts, the intensity and frequency of which are increasing due to human interventions. Some areas of Sri Lanka are also periodically subject to cyclones that occur due to climatic conditions and geographical locations.Land degradation denotes all natural or anthropogenic processes that diminish or impair productivity of land.

Mitigating soil erosion through farm-level adoption of soil and water conservation measures in Samanalawewa Watershed, Sri Lanka

Journal Articles & Books

Sri Lanka

Soil erosion by water is currently one of the most notable types of land degradation in Samanalawewa Watershed in Sri Lanka, creating copious environmental and socioeconomic impacts. Thus, with the aim of detecting and mapping the rates of human-induced soil erosion in the watershed, remote sensing and geographic information system based modelling and field experiments were carried out.

The net effect of heavy grazing and land degradation on plant diversity and richness is insufficiently understood for incorporation in national biodiversity assessments. A study was undertaken to determine the effects of heavy grazing primarily on richness of vascular plant species across the arid and semi-arid rangeland biomes of South Africa. Major grazing contrasts were systematically identified for sampling in rangelands of Succulent Karoo, Nama-Karoo, Thicket, Grassland, Kalahari dune savanna and Mopane savanna.

Linkages between land management, land degradation, and poverty in Sub-Saharan Africa: The case of Uganda

Poverty reduction and sustainable land management are two objectives that most Africancountries strive to achieve simultaneously. In designing policies to achieve theseobjectives concurrently a clear understanding of their linkage is crucial. Yet there isonly limited empirical evidence to demonstrate the linkage between poverty and land managementin Africa. Using Uganda as a case study, this analysis seeks to better understand thislinkage. We used several poverty measures to demonstrate the linkage between poverty and anumber of indicators of sustainable land management.

Reflectance spectroscopic approach for estimation of soil properties in hot arid western Rajasthan, India

Índia

Periodic and regular assessment of land degradation in arid regions of the world is essential for implementing suitable corrective measures in time. Assessment of soil properties based on soil sampling from hot arid tracts followed by laboratory analysis is a formidable task. Reflectance spectroscopy appears to be an emerging technology for the assessment of soils in extreme environment.

Best management practices to face degraded territories occupied by Cistus ladanifer shrublands – Portugal case study

Journal Articles & Books
Dezembro, 2015
Portugal

Land degradation in the Mediterranean Basin is clearly connected to the resilience of perturbed ecosystems, contributing to land abandonment, recurrent fires and biodiversity loss, with the prevalence of secondary shrublands that tend to occupy large areas. This is the case of Cistus ladanifer shrublands, one of the most widespread shrub communities in the Iberian Peninsula and a poor, uniform and resilient system. Here, we analyse the impact of several management practices in the recovery of territories largely occupied by this shrubland.
