The purpose of this study is to measure the effect of land degradation and the environmental changes on agricultural productivity in Somalia, as well as the other factors that affect crop production in Somalia.

Cobb-Douglas production function assumes crop production as a dependent variable and land degradation, labor, capital, fertilizer and climate change as the explanatory variables. In this study time-series data (1962–2017) collected from the Food and Agriculture Organization and World Development Indicators were used. The unit root of the data was examined using Ng-Perron and the Lee-Strazicich methods to explore the unit root property of the breaks. Structural breaks are observed using the Chow test, and the long-run relationship between the variables is examined using Gregory and Hanssen's approach.

This study found that land degradation and climate change have a negative relationship with agriculture production in Somalia. Land degradation leads to the decline in agricultural production as the loss of one hectare of land due the depletion causes agriculture production of Somalia to fall by about five percent. Climate changes and warming of the environment lead to the reduction of agriculture production. One degree Celsius rise in the temperature leads to a three percent decline in agricultural production. Capital contributes immensely to agricultural production as one unit of additional capital raises production by seven percent. The contribution of labor to agricultural production is limited because of land contraction

Land degradation is a significant contributor to the decline of agricultural production. As land degradation continues to worsen, rural poverty increases, which in turn causes the rural migration and the social conflict. The government should develop land improvement programs such as increasing market orientation of the farmers, encourage private sector engagement in agribusiness and establish a regulatory framework of the land uses.

This study examines the structure of the time-series and specifies the break periods to determine when and where significant and sudden changes occurred within land degradation and agricultural production. The study employs advanced econometric methods, namely, Ng-Perron method and the Lee-Strazicich method to test the unit root property of the breaks. It also examines the long-run relationship between the variables using Gregory and Hanssen's approach.

Arid ecosystem covers one third of the Earth's surface and is the home town of majority of the population of the world. This ecosystem is also important because it has significant roles in land and water resources management. However, due to anthropogenic land use activities or shifting climate conditions, the features of the ecosystem change and cause diminished vegetative cover, reduced productivity, increased soil erosion, invasion of exotics, and loss of native species. Moreover, in the recent years, earth's vegetative cover may exceed the ecosystem's capacity to adapt, which happens through the consequence of rapid land degradation along with desertification. Therefore, this chapter provides how different regions endeavor with this arid ecosystem by performing various adaptation practices.

The purpose of this paper is to discuss some of the implications of policies, practices and new “non‐equilibrium” management approaches in mobile grassland management.

The author takes an actor‐oriented perspective on the narrative of land‐use practices, notional sustainable stocking rates and the problematic of state policy interventions in local context. The paper is based on two years in the field on a bilateral aid‐funded grassland management project at Xing'an League, Inner Mongolia and follow‐up among selected informants.

The constitution of grasslands “degradation” is in fact contested by resource users. Most grassland scientists, Party and Government officials in China have tended to associate ethnic “minority” mobile pastoralists with destructive cultural practices that, they argue, have led to ecological decline on the steppes. This argument is integral to the “degradation narrative” that underpins the discourse on grassland science. The conventional bio‐ecology emphasis on species dominance (growth‐form), in fact says little about the extent of anthropogenic impacts on above‐ground biomass and whether these factors have been the cause of degradation. The paper suggests that greater consideration is given to specific changes in human activity, climatic and plant productivity over time and space, based on endogenous, flexible seasonal estimates.

Although presenting challenges to conventional grassland science based on endogenous experiences and herder practices, it may have specific geopolitical limits to more general scaling‐up in different contexts.

The paper discusses new modalities of non‐equilibrium grassland management, inverting normative top‐down approaches to controlling environmental degradation, livestock distribution and stocking rates.

The paper suggests rethinking the use of customary practices, vernacular knowledge and the social organisation of herders in the design of sustainable grassland management.

The paper may be valuable to practitioners, rural development planners, funders and researchers interested in the use of integrated, cross‐disciplinary, new ecological knowledge in grassland management.

The purpose of the study is to assess the environmental and socio‐economic impacts and risks of climate change through GIS database management system (DBMS) on land use‐informatics and climate‐informatics. The Dabka watershed constitutes a part of the Kosi Basin in the Lesser Himalaya, India in district Nainital has been selected for the case illustration.

Land use‐informatics consists of land use mapping and change diction, i.e. decadal changes and annual changes. Climate‐informatics consists of climate change detection through daily, monthly and annual weather data for a period of 25 years.

The exercise revealed that oak and pine forests have decreased, respectively, by 25 percent (4.48 km²) and 3 percent (0.28 km²) thus bringing a decline of 4.76 km² forest in the watershed during 1990 to 2010. But, due to climate change the mixed forest taking place of oak forest in certain pockets and consequently the mixed forest in the catchment increased by 18 percent (2.3 km²) during the same period which reduced the overall loss of forests in the region but its not eco‐friendly as the oak forest. Barren land increased 1.21 km² (56 percent), riverbed increased 0.78 km² (52 percent) and cultivated land increased about 0.63 km² (3 percent) during the period of 1990 to 2010. Out of the total seven classes of the land use land cover, five classes (i.e. Oak, Pine, Mixed, Barren and Riverbed) are being changed dominantly due to climate change factor and anthropogenic factors plays a supporting role whereas only two classes (scrub land and agricultural land) are being changed dominantly by anthropogenic factors and climate change factors plays a supporting role. Expansion of mixed forest land brought out due to upslope shifting of existing forest species due to climate change factor only because upslope areas getting warmer than past with the rate of 9°C‐12°C/two decades. Consequently, the results concluded that the high rate of land use change accelerating several environmental problems such as high runoff, flash flood, river‐line flood and soil erosion during monsoon season and drought during non‐monsoon period. These environmental problems cause great loss to life and property and poses serious threat to the process of development with have far‐reaching economic and social consequences.

This study generated primary data on land use‐informatics and climate‐informatics to integrate each‐other for impact assessment and mitigation through sustainable land use as constitutes a part of a multidisciplinary project, Department of Science and Technology (D.S.T.) Government of India.

The purpose of this paper is to examine the introduction of three specific fiscal flexible mechanisms such as VAT surcharges/discounts, surcharges on import/manufacture of risk substances and maturity land tax to implement a new environmental fiscal reform that aims to reduce pollutions and emissions and avoid a regressive impact on low-income households using a feedback system.

The idea behind this article is to explore alternative environmental taxation system that aims to foster the transition to social-ecological sustainability without affect negatively poor and low-income households. It looks at the potential of environmental fiscal reform in terms of environmental benefits and present in the first section, evidence of some economic regressive impact caused by environmental fiscal reform in European Union from previous empirical studies. The article then introduces of a feedback mechanism to create a repayment system, such as rebate or cash transfer to compensate the regressive effect of the levy being added to the consumer price affecting low-income households in a very short period and push consumers to buy alternative eco-friendly products and services and to stimulate the market to offer them.

Lowering VAT rate for green products and services has the potential to increase demand for sustainable products and services and stimulate green jobs. Surcharges on import and manufacture of risk substances play a significant role to discourage the import of hazardous and pollutant substances by putting price on them and push the industrial sector towards a medium and long-term transition. Lowering taxes rates for buildings in inner cities encourage improvements and renovations, while raising tax on peri-urban areas discourage land speculation in areas with higher grade of biodiversity. This fiscal mechanism indirectly will reduce private and public transport emissions caused by urban sprawling and travel costs, reduce public infrastructure costs for connecting suburban area to the inner city and reduce the loss of urban-edge farmland area that are vital for smart urban growth.

The previous studies on the economic impact of the on environmental fiscal reform analysis, have focused on environmental aspects, economic growth and employment, but little on the regressive impact in short and medium terms on least wealthy sections of society. The proposed feedback mechanism aims to reduce distortion and inequalities caused by surcharges on existing taxation to low-income using monetary repayment measures, especially for products and services with elastic demand and no substitutes.

The Turkish Mediterranean region covers an area of 198.165km², including ten states and a coastline of about 4,389km. The area has served as a womb for several civilisations. However, its rich plant diversity has been victimized through anthropomorphic pressures. Southwestern shores of Turkey are the main centre of coastal endemism in the Mediterranean basin. The flora in the region on the whole includes more than 700 endemics, out of which about 600 are East‐Mediterranean elements. Out of the endemic taxa distributed in the region more than 40 are facing a threat of extirpation. The region embodies tertiary endemics as well, like Liquidamber orientalis, Eryngium thorifolium and Flueggea anatolica. High mountain zones abound in neoendemics. Although several protected areas have been created lately, demographic pressure, urbanisation, grazing, fires and erosion, are still posing a great threat to the plant diversity. This paper enlightens the impact of the aforementioned land degradation processes on the plant cover of this phytogeographical region in Turkey.

To investigate whether the desertification risk index (DRI) which was originally developed for the coastal area of Turkey in a previous work, could be used as an effective desertification indicator in other Mediterranean areas such as the Lebanon.

The calculation of the DRI is based on the use of climatic factors and the normalized difference vegetation index (NDVI). As a result, climatic data were obtained and spatial interpolation techniques were applied to derive temperature and precipitation maps within a GIS environment while the NDVI was derived from satellite imagery. Spatial models were employed in order to produce the DRI map of Lebanon. Geographical analysis and standard statistical techniques were employed to investigate the relationships between: desertification risk and two topographic factors, namely, elevation and distance from the sea and desertification risk and the type of land cover. The accuracy of the index was assessed by comparison with recently published official maps and documents.

The paper demonstrates the efficiency of a desertification index to identify areas at risk. The DRI map proved to be accurate when compared to the map of desertification prone areas recently produced by the Lebanese Ministry of Agriculture. The areas with the highest degree of desertification risk are located in the North‐Eastern part of the country, in the area of the Bekaa Valley. This is in agreement with the reports of the United Nations Convention for combating desertification. A strong correlation was found between desertification risk and distance from the sea (the larger the distance the higher the risk) while shrubland appears to be the land cover type with the highest risk of desertification.

This research work demonstrates how satellite imagery and modern spatial analysis techniques could provide an essential alternative to traditional methods.

The purpose of this paper is to develop the Great Green Wall (GGW) Project initially financed by the United Nation’s Global Environment Facility Trust Fund, is a Pan African proposal in greening the Sahel of Africa from West (Dakar) to the East (Djibouti). It aims at reducing poverty and soil degradation in this region, taking into account the effects of desertification and climate change on sustainability of livelihoods.

Several desertification attenuation projects in Nigeria are employing different methods for maximum benefits obtainable from the objectives of the particular projects. As noted above, however, the approach of GGW is to improve the alternative livelihoods of the people by their active participating in the implementation of the project. It is also noted that environmental impact assessment, community reconnaissance or needs assessments might be initial part of pre-project activities, thereby making the communities more aware and educated of the impending environmental problems.

Desertification has reached an alarming state in Nigeria. The frontline desert threatened States of Nigeria constitute 43 percent of the land mass of the country. With increased pressure of desertification, exacerbated by a period of prolonged drought of more than 20 years, climate change and human activities, it is becoming increasingly difficult to obtain sustainability in the management of the fragile lands and the region’s ecosystem. Strategic interventions in combating the problem of desertification in Nigeria have attenuated some of the detrimental social, economic and environmental impacts on the affected communities. Programmes and projects have strengthened the resilience of the people, participating in sand dune stabilization, the Great Green Wall Sahara Sahel Initiative, including shelterbelt developments. Government has sustained inputs in environmentally friendly agriculture and also encouraged synergetic collaborative activities with international and national NGOs, international agencies and local institutions.

These results/activities give evidence of the increased public awareness of environmental degradation due to desertification and climate change in Nigeria; the realization in environmental stabilization needs with ready participation of the communities for improved livelihoods in environmental activities and arid agriculture as supported by the National Great Green Wall (NAGGW) program of the country; resulting in internalization of these projects supporting livelihoods for sustainability in the Sahel of Nigeria.

The purpose of this paper is to show how typologies for environmentally induced population movement need to be understood in a contextualised manner in order to be useful.

This study interrogates some academic discourses concerning environmentally induced population movement. By analysing key environmental factors said to contribute to population movement, in addition to considering time factors, this study uses the case of Tuvalu to demonstrate overlapping categories and the importance of contextualisation.

Current typologies provide a basis for considering a wide variety of motives for environmentally induced population movement, in relation to different drivers, motivations, time scales, and space scales. Yet contextualisation is required for policy and practice relevance.

All typologies have limitations. Any typology should be taken as a possible tool to apply in a particular context, or to support decision making, rather than presenting a typology as universal or as an absolute without dispute.

Rather than disputes over typologies and definitions, bringing together different views without reconciling them, but recognising the merits and limitations of each, can provide a basis for assisting people making migration decisions.

None of the typologies currently available applies to all contexts of environmentally induced population movement – nor should any single typology necessarily achieve that. Instead, it is important to thrive on the differences and to contextualise a typology for use.

The purpose of this paper is to identify the main environmental impacts of coal mining in China, examine the main institutions and reform factors that failed the control of these damages, and discuss what would be necessary to establish a sustainable and environmentally responsible coal mining sector in the context of market and institutional reforms.

Review of existing knowledge, and semi‐structured interviewing with key informants in the policy and industry sectors has been the main method of primary and secondary data collection. Grounded theory was used to analyze original data.

The large and fast growing coal industry in China has caused significant environmental degradation, including land subsidence and water intrusion, as well as remarkable records of miner's poor safety and health. Market reform was mostly unsuccessful in integrating environmental consideration into production and marketing decisions. Main factors of reform that have been associated with this problem are price deregulation and excessive competition inside the industry. Institutional reform, in fact, enhanced the status of State Environment Protection Agency; however, it impaired environmental governance in the coal industry. It is suggested that market reform as applicable to the China coal industry economic sector in particular should reconsider its approach in light of the numerous problems it has created.

The paper identifies and puts together the condition of the growing coal industry in China after market reform, articulating the huge environmental costs that this development has imposed on the country, while calling for an environmentally sustainable coal industry.
