With the ongoing climate change scenario and alarmingly increased land degradation, understanding complex interactions of drought stress and organic fertilizers on morpho-physiological traits and dynamics of nutrient concentration is pivotal for sustainable production leafy vegetables such as mustard (Brassica juncea). Thus, this study evaluated the effect of drought stress and organic fertilizers on B. juncea growth, physiology, and dynamics of nutrient concentration at the vegetative stage.

Conversion of native lands into agricultural use, coupled with poor land management practices, generally leads to changes in soil properties. Understanding the undesirable effects of land-use and land-cover (LULC) changes on soil properties is essential when planning for sustainable land management.

The paper deals with analyses and propositions for adaptive governance of an alpine (A) and an Ethiopian (B) agropastoral system with common-pool pastures. Sustainability can be enhanced by augmenting (i) the ecological and social capitals in relation to costs and (ii) the resilience or adaptive capacity. In (A), a multifunctional agriculture appears to maintain the ecological capital providing many ecosystem services. In (B), the ecological capital can be increased by reversing the trend towards land degradation.

In recent years it has become clear that climate change is an inevitable process. In Sub-Saharan Africa, the expectation is that climate change will have an especially negative impact, not only a result of projected warming and rainfall deficits, but also because of the vulnerability of the population. The impact upon food security will be of great significance, and may be defined as being composed of three components: availability, access, and utilization.

Many observers view Jatropha as a miracle plant that grows in harsh environments, halts land degradation and provides seeds for fuel production. This makes it particularly attractive for use in Ethiopia, where poverty levels are high and the degradation of agricultural land is widespread. In this article, we investigate the potentials and limitations of a government-initiated Jatropha project for smallholders in northeastern Ethiopia from a green economy perspective.

Soil degradation in India is estimated to be occurring on 147 million hectares (Mha) of land, including 94 Mha from water erosion, 16 Mha from acidification, 14 Mha from flooding, 9 Mha from wind erosion, 6 Mha from salinity, and 7 Mha from a combination of factors. This is extremely serious because India supports 18% of the world’s human population and 15% of the world’s livestock population, but has only 2.4% of the world’s land area. Despite its low proportional land area, India ranks second worldwide in farm output.

The plant–microbe–soil nexus is critical in maintaining biogeochemical balance of the biosphere. However, soil loss and land degradation are occurring at alarmingly high rates, with soil loss exceeding soil formation rates. This necessitates evaluating marginal soils for their capacity to support and sustain plant growth. In a greenhouse study, we evaluated the capacity of marginal incipient basaltic parent material to support native plant growth and the associated variation in soil microbial community dynamics.

A gigantic project named Gully Land Consolidation (GLC) was launched in the hill-gully region of the Chinese Loess Plateau in 2011 to cope with land degradation and create new farmlands for cultivation. However, as a particular kind of remolded loess, the newly created and backfilled farmland may bring new engineering and environmental problems because the soil structure was disturbed and destroyed. In this study, current situations and characteristics of GLC are introduced.

Despite its contributions to the development of the country, the mining sector in Sierra Leone, has been attributed to a multitude of impacts on the environment. This article focuses on assessing the environmental impacts of mining in mining edge communities in Sierra Leone. A survey of 360 people from three mining edge communities (Sierra Rutile Limited (SRL), Bonthe district; Octea Mining Company (OMC), Kono district and Sierra Leone Mining Company (SLM), Port Loko district) was conducted.

The study set out to understand drivers of Land-Use Land Cover (LULC) changes in dry-land areas and investigate factors helping mitigate the adverse impacts of climate anomalies on LULC changes. By employing a mixed-methods design, it combined LULC data with socioeconomic and climatic data, to analyze the pattern of LULC changes and its socioeconomic and climatic driving forces along with moderating factors. It was found that rangeland decreased by 764 km2 (13% of total area) between 1986 and 2015.
