Cooperation in earth observation missions in Africa: a role for afrigeoss

This paper is aimed at examining the role of African Global Earth Observation System of Systems (AfriGEOSS) in Earth Observation (EO) mission cooperation on the continent of Africa. It discusses the importance of earth observation programs for developing countries as well as the benefits of international cooperative efforts. The paper further examined some collaborative projects on Earth Observation in Africa and their associated problems. It specifically looked at the EO data coordination initiatives such as the Spatial Data Infrastructure (SDI), GEOSS, Africa Discovery Broker, etc. It then situates AfriGEOSS in the context of African Space Agenda (ASA) with recommendations especially to the Africa Union Commission for the realization of ASA set goals. The paper reiterated that regardless of whether developed or developing, Earth observation information provides substantial benefit supporting economic development, decision making and policy implementation of all countries of the world. This is as a result of its multifarious benefits to humans in areas like agriculture, forestry, risk management, disaster monitoring, maritime, defence and security and natural resources management. Consequently, the paper argued that the numerous benefits from space assets have driven countries within the continent of Africa to either acquire or develop capabilities in space systems which is devoted to improving quality of life in general. The paper concluded that while space systems are expensive, there is need for continuity and sustainability as a result of its numerous advantages to the human’s society.

A critical overview of transboundary aquifers shared by South Africa

Transboundary groundwater commonly implies a body of groundwater intersected by a political border with the attendant potential threat of dispute over a shared resource. This definition is inadequate in many parts of southern Africa. Approximately 96% of South Africa’s borders are underlain by low-yielding aquifers and, coupled with a low demand for water attendant on low population density, the risk of over-pumping or pollution leading to dispute is low, and a modified understanding is required. Examples of transboundary aquifers are used to illustrate implications for policy and management of southern African transboundary groundwater resources, where transmissivities are low and, less commonly, where over-pumping may indeed be a problem. The general lack of technical cooperation, data sharing, training and research between the riparian states on hydrogeology hampers a mutual understanding of the resources. The concept of transboundary groundwater must necessarily include aquifers where little cross-border flow occurs, but where cross-border cooperation will help to ensure sustainable cooperative utilisation of shared aquifer resources. This is imperative if future disputes are to be averted. Agreement between scientists is a necessary precursor to broader transnational governance agreements in regard to shared water resources, and recent initiatives by the Orange-Senqu River Commission promise closer integration.     

Sustainable development and the exploitation of mineral and energy resources: a review

Natural resources, e.g., metals, industrial minerals, water, and soil, are the essential basis for our economy and well-being. We have to know where these raw materials come from and how they are mined. Sustainable development requires the maintenance, rational use and enhancement of natural resources, as well as a balanced consideration of ecology, economy and social justice. Four general rules concerning the implementation of sustainable development for renewable and non-renewable resources are discussed. Examples of the consumption of selected materials from historical times to the present day are presented, as well as of regional distribution, usage (in contrast to consumption), lifetimes of resources, the supply-and-demand cycle, recycling and substitution in modern times. To fulfill the requirement of sustainable development, the efficiency with which resources are utilized has to be improved. The learning process, often driven by financial rewards, leads from one technology to a better one, thus increasing the efficiency of the use of a resource or commodity. Examples of learning curves are discussed. Industrial countries have to transfer their advanced technologies to developing countries in order to avoid undesirable development in the mining industry and use of natural resources in those regions. The use of the best available technology by the mining industry, taking into account economic considerations, and the necessity to establish environmental guidelines are essential if environmental impact of the production of non-renewable resources is to be minimized. Far more critical than the production of non-renewable resources under the aspect of sustainable development and the capacity of the pollutant sinks of the Earth is the element of natural attenuation with regard to the resources soil and water.     

Towards a pro-community-based water resource management system in Northwest Cameroon: practical evidence and lessons of best practices

This paper examines community-based water supply management (CBWSM) in three rural districts of Northwest Cameroon as well as a review of the literature focusing on some successful community-based natural resource management initiatives in sub-Saharan Africa. Using empirical and secondary data collected through participatory research methods, it is argued that CBWSM has failed to achieve sustainable water supplies in Northwest Cameroon. Findings revealed that centralized control, the prevalence of poverty, passive involvement of public, private and grassroots community has continued to thwart water supplies within these districts. It is important to note that in any natural resource management system, power becomes a crucial factor as it determines who has and does not have access to common-pool resources. This paper argues that argues that strong traditional leadership, resolute devolution, and active participation of rural communities will facilitate and invigorate a platform for capturing the views of diverse user groups and this can bring about a people-centered and community-driven development process. Some aspects of best practice arising from successful case studies in Cameroon can contribute significantly to promoting the development of effective CBWSM in other rural communities with similar characteristics in and out of Cameroon. This will be possible only if rural groups are involved and engaged in the management of their resources while integrating some aspects of best practice.

     

Community mobilisation for improved livelihoods through tree crop management in Niger

Effective natural resource management requires interrelated technical practices and social arrangements that are appropriate to a region’s biophysical characteristics and that address protection and sustainable management of resources. This is illustrated from our experience in the Republic of Niger, West Africa. In 1980 barren plains, infertile soils, drought, dust storms, severe fodder shortages, and agricultural pest outbreaks were normal occurrences in Niger’s rural regions. In general, despite large investments of time and funding, conventional reforestation efforts had little impact. However by 2008 over five million hectares of once barren land had been transformed through wide adoption of an agroforestry method known as ‘Farmer Managed Natural Regeneration’ (FMNR), introduced in 1983. In the Aguie Department, the practice of FMNR was formalized through the Desert Community Initiative (DCI), addressing interrelated technical and social issues in resource management. New governance structures, which include marginalized groups, implement monitoring and enforcement systems enabling communities to manage land and regenerating trees. These, together with technical solutions that build on local knowledge and skills and use previously undervalued indigenous tree species, have generated a sustainable fuel-wood market for the first time. Increased linkage and compatibility between institutions at local and national levels and strengthened social capital have been crucial to these impacts. Food security and community resilience to drought have been markedly enhanced and local incomes have increased. The experience provides important lessons for approaches to addressing environmental degradation and poverty in other semi arid areas and facilitating the spread and adoption of new agroforestry systems.

Towards sustainable agriculture in post-apartheid South Africa

This paper assesses the possibility of sustainable agriculture in South Africa in the context of recent policy initiatives. The new environmental strategy for agriculture represents a significant break with policy initiatives developed during apartheid. The likelihood of sustainable farming practices being adopted in South Africa will, however, face at least three obstacles. These are the integrated structure of industrial farming, the concern over yields, and current political and economic changes in South African agriculture. It is argued that sustainable techniques are unlikely to develop in the large scale farming sector in the near future. If the considerable research and extension resources of the state are reoriented quickly enough, sustainable farming methods can be embraced by an emerging class of black commercial farmers.

Analysis on exploitation status,potential and strategy of groundwater resources in the five countries of Central Asia

As an important part of water resources of the five countries of Central Asia, groundwater resources give critical supports to the regional economic development. Accompanied by rapid economic development, the demand of groundwater is increasing. As a result, the governments are paying more attention to groundwater resource development and utilization. However, there are noticeable issues and contradictions in water resource exploration in these countries. To be more specific, these countries lack the studies in development potential and conception planning, thus influencing the sustainable groundwater development. This paper mainly discusses groundwater development problems in the five countries of Central Asia, and briefly introduces volumes and distribution of transboundary groundwater. In addition, it analyzes the current exploitation status of groundwater and studies the potential in utilizing the resource. Most importantly, it proposes creative ways to address groundwater development issues: To make best of the resource, international cooperation is required.     

Asian Transboundary Aquifers Inventory and Mapping

Transboundary aquifer (TBA) is an aquifer system that exists in more than one state. As an important component of the groundwater system, proper management and rational utilization in trans-boundary aquifers are significantly important for promoting sustainable development and good-neighbor relationships. The Transboundary Aquifers will not implicate by the country’s political boundary as it follows the natural boundary lines. Within the frame work of the UNESCO''s International Hydrological Programme (IHP-VI & VII) activities for the International Shared Aquifer Resource Management (ISARM), the inventory on TBA in Asia both preliminary and detail has accomplished. Those TBAs are classified in to two types: regional and local grade. A of Asian Transboundary Aquifers Map has advanced. The updated map provides the situation of the regional TBAs identify as the actual shape. Countries with the TBAs should strengthen cooperation for coordination and joint management of groundwater resources in order to achieve sustainable use     

Application of the “Accurate Control Groundwater Resources” Theory in Containment of Groundwater Resource Exhaustion Trend

The continued sustainable economic development of china depends in part, to the scientific management of China’s precious groundwater resources in the coming years. Groundwater resource scarcity is a common underlying problem across China, in addition, the large-scale groundwater exploitation for human consumption over recent decades has resulted in a series of environmental geological problems. As a result of these problems, the national economics in china have been seriously affected. In order to prevent groundwater resource exhaustion and environmental geology deterioration, “accurate control of groundwater resources (ACGR)” theory and its support system were established in this article, and the related prevention measures of the ACGR theory, such as accurate irrigation, accurate supply water, and accurate subsidies, were proposed. This paper highlights the ACGR theory as an efficient and essential way to achieve the sustainable groundwater resource management, which can be applied to countries such as China.     

Tendency Analysis of Socio-hydrology Research Based on Bibliometrics

Socio-hydrology is a new inter-disciplinary science of people and water. The biblio-metrical analysis was made on the socio-hydrology papers included in the Web of Science (WoS) to obtain the study progress of socio-hydrology. The results indicated that the research areas of socio-hydrology mainly covered water resources, environmental sciences, civil engineering, geosciences, environmental engineering, agronomy, environmental studies, ecology, meteorology and atmospheric sciences, and geography. The key topics in general socio-hydrology were water resources, agricultural irrigation, and water policy. Furthermore, the research spots varied with the needs of the societal development in the different decades. They also varied among countries. The special socio-hydrology research mainly focused on water need and security in both urban and rural development, and emphasized the decision support of scientific management through effective hydrological model prediction. Its development will promote the sustainable management and utilization of water resources and help better solve water problems facing the humans.     

Renewable energy in Iran: Challenges and opportunities for sustainable development

Around the globe, developing countries have reported different cases of successfully implemented Renewable Energy (RE) program supported by bilateral or multilateral funding. In developing countries subsidy has played a big role in RE program marketing and whether this will lead to sustainable development is yet to be determined. The adoption of implementation strategies that will support sustainable development and overcoming barriers that hinder expansion of Renewable Energy Technologies (RETs) still remains as a big challenge to stakeholders involved in promotion of RE resources in developing countries. In this respect, developing countries need to re-examine their environmental policy for promotion of RETs in order to define its role in revitalization of their economies. This paper reviews the policy incentives for promotion of RETs in the Islamic Republic of Iran. Setting-up international collaborative business ventures between local industry in Iran and RE companies in developed countries is proposed as an implementation strategy that will appropriate diffusion of RETs in the country. An organizational framework that may help to attain this objective is discussed and a structural model for RE business partnership is presented. It is concluded that with appropriate policy formulations and strategies, RETs can bring about the required socio-economic development in Iran.     

The Distribution of Petroleum Resources and Characteristics of Main Petroliferous Basins along the Silk Road Economic Belt and the 21st-Century Maritime Silk Road

The Silk Road Economic Belt and the 21st-Century Maritime Silk Road Initiative, abbreviated as the Belt and Road Initiative, is a primary development strategy of China’s future international cooperation. Especially, the energy resource cooperation, including oil and gas resources cooperation, is an important part of this initiative. The Belt and Road has undergone complicated geological evolution, and contains abundant mineral resources such as oil, gas, coal, uranium, iron, copper, gold and manganese ore resources. Among these, Africa holds 7.8% of the world’s total proven oil reserves. The oil and gas resources in Africa are relatively concentrated, with an overall low exploration degree and small consumption demand. Nigeria and Libya contain the most abundant oil resources in Africa, accounting for 2.2% and 2.9% of the world’s total reserves, respectively. Nigeria and Algeria hold the richest natural gas resources in Africa, occupying 2.8% and 2.4% of the world’s total reserves, respectively. Africa’s oil and gas resources are mainly concentrated in Egypt, Sultan and Western Sahara regions in the northern Africa, and the Gulf of Guinea, Niger River and Congo River area in the western Africa. The Russia–Central Asia area holds rich petroleum resources in Russia, Kazakhstan, Turkmenistan and Uzbekistan. The potential oil and gas areas include the West Siberia Basin, East Siberia Basin and sea continental shelf in Russia, the northern and central Caspian Basin in Kazakhstan, the right bank of the Amu-Darya Basin, the East Karakum uplift and the South Caspian Basin in Turkmenistan, and the Amu–Daria Basin, Fergana Basin, Afghan–Tajik Basin and North Ustyurt Basin in Uzbekistan. The Middle East oil and gas resources are mainly distributed in the Zagros foreland basin and Arabian continental margin basin, and the main oil-producing countries include Saudi Arabia, Iran and Iraq. The Asia Pacific region is a new oil and gas consumption center, with rapid growth of oil and gas demand. In 2012, this region consumed about 33.6% of the world’s total oil consumption and 18.9% of the world’s total natural gas consumption, which has been ranked the world’s largest oil and gas consumption center. The oil and gas resources are concentrated in China, Indosinian, Malaysia, Australia and India. The abundant European proven crude oil reserves are in Norway, Britain and Denmark and also rich natural gas resources in Norway, Holland and Britain. Norway and Britain contain about 77.5% of European proven oil reserves, which accounts for only 0.9% of the world’s proven reserves. The Europe includes main petroliferous basins of the Voring Basin, Anglo–Dutch Basin, Northwest German Basin, Northeast German–Polish Basin and Carpathian Basin. According to the analysis of source rocks, reservoir rocks, cap rocks and traps for the main petroliferous basins, the potential oil and gas prospecting targets in the Belt and Road are mainly the Zagros Basin and Arabic Platform in the Middle East, the East Barents Sea Basin and the East Siberia Basin in Russia–Central Asia, the Niger Delta Basin, East African rift system and the Australia Northwest Shelf. With the development of oil and gas theory and exploration technology, unconventional petroleum resources will play an increasingly important role in oil and gas industry.     

Vulnerability of water resources in northern Cameroon in the context of climate change

Water resources in northern Cameroon have continuously been reducing over the past years. Many studies have suggested two principal causes: (1) human activities such as poor farming practices, unsustainable use of water resources, increased demand of water, deforestation, land-use change, etc., (2) human-induced climate change. Northern Cameroon in this study includes: the Adamawa, North and Far North regions located closer to the Sahel regions of Africa. These regions are already water stressed because of their location and any further change in climate with rising temperature would impact water resource either positively or negatively. Time series analysis and a 12-month standardized precipitation index (SPI12) with digital data between 1957 and 2006 were used to investigate the variation of water resources in northern Cameroon. Results obtained varies between the different regions with an increased annual trend in temperature and precipitation for Ngaoundere (Adamawa region) and Garoua (north region), whereas Maroua (far north region) had a decreased annual trend in both precipitation and temperature. Further variability results obtained from a SPI12 show that wetter period out number drought period in all three regions. The study concluded that water resources vary with the changing climatic condition and the severity of the impact varies from region to region. Furthermore, water deficiency in northern Cameroon might not be due to climate change. The reasons might be a combination of poor water management and other factors such population growth, the environmental condition, etc.     

Geology,geomorphology, hydrology,groundwater and physical resources of the desertified Badia environment in Jordan

This paper summarizes the information on the geomorphology and physical resources component of the Jordan Badia Research and Development Programme. The research focuses on the issue of the environment in arid lands and aims to provide practical options for sustainable development, for the benefit not only of the Hashemite Kingdom of Jordan but for other arid regions of the world. The research is significantly development driven because there is a need to identify useable natural resources and establish a framework for their effective exploitation and management in a marginal, fragile environment, which is sensitive to change.Pressure for development of the Badia stems from the fact that the great majority of the population in Jordan is compressed into less than 10% of the country by environmental constraits. It is hoped that the Jordan Badia Research and Development Programme will provide the required framework to ease current environmental pressures, encourage migration to the Badia, a sparsely populated region, and establish economically and ecologically self-supporting communities.This paper discusses the following areas that are related to the sustainable development of the Jordan Badia with special emphasis on the Safawi area in the Northern Jordan Badia; geomorphology including landform, processes and hazards, geology and physical resources, hydrology, surface water and water engineering, groundwater, soils and vegetation, sediment erosion and mobility and environmental management.
