DOWNLOAD EBOOKThe irrigated area in the Aral Sea basin totals about 7. 5 million hectare. Part of the water supplied to this area is consumed by the irrigated crop; the remainder of the supplied water drains to the groundwater basin, to downstream depressions, or back to the rivers. During its use, however, this drained part of the water accumulates salts and chemicals. The disposal of this polluted water causes a variety of (environmental) problems. If the percentage consumed water of the total water supply to an irrigated area (the so-called overall consumed ratio) can be increased, less water needs to be drained. This alleviates part of the related (environmental) problems. Further, if the overall consumed ratio for the above 7. 5 million hectare is improved, less water needs to be diverted from the rivers. Hence, more water can flow towards the Aral Sea. As mentioned above, part of the non-consumed irrigation water drains to the groundwater basin. Commonly, the natural discharge capacity of this basin is insufficient to handle this imported water. As a result, the groundwater table rises towards the land surface causing waterlogging. In (semi-)arid zones this waterlogging triggers a soil salinity problem resulting to a significant reduction in crop yields. The artificial increase of the discharge capacity, and lowering of the groundwater table, solves the soil salinity problem.

DOWNLOAD EBOOKThe Government of Tajikistan should consider joining the Global Methane Commitment as a strategic and prudent decision. Tajikistan's participation in the Global Methane Pledge offers numerous benefits that can positively impact the country's economy, environment, and global reputation. By joining this international effort to reduce methane emissions, Tajikistan can contribute to global climate change mitigation goals, demonstrating its commitment to addressing environmental challenges. This commitment becomes particularly significant for Tajikistan's agrarian economy, where sustainable livestock management practices can help reduce methane emissions from enteric fermentation, enhancing both environmental sustainability and agricultural efficiency. Additionally, the pledge emphasizes improved waste management and methane capture from solid waste sites, aligning with Tajikistan's green energy objectives, carbon market participation, revenue generation, and attracting international investments. Importantly, joining the Global Methane Pledge involves no legal obligations or penalties, offering Tajikistan a flexible and supportive framework for collaboration, knowledge sharing, funding access, and effective methane reduction measures implementation. Targeting main sources of methane emissions provides an opportunity to implement cost effective measures that yield multiple benefits, including improved air quality, reduced health risks from air pollution, enhanced energy efficiency, increased energy security, and the development of sustainable technologies and industries that foster economic growth and job creation. It is recommended that comprehensive studies be undertaken within each of the sub-sectors such as agriculture, energy, waste management and wastewater management. These studies will not only provide valuable insights to inform effective interventions, but also provide a basis for future re search and data-driven decision-making. It is also important to highlight that some measures can lead to cost avoidance in the long run. By focusing on mitigating methane emissions, Tajikistan can actively contribute to global climate change mitigation while reaping numerous positive out comes for its environment, public health, and economy. To determine the effects of measures, effective measurement is needed. Tajikistan has been improving the management and use of statistical data in recent decades as its Agency for Statistics under the President of the Republic of Tajikistan (TajStat) works closely with regional and international partners to improve data quality and reporting. However, the agency needs additional human and financial resources to support the collection of climate data and the development of indicators to monitor progress and to support sound policy decisions.

DOWNLOAD EBOOKThis book presents the results of the Interdisciplinary Research Group "Society – Water – Technology" of the Berlin-Brandenburg Academy of Sciences and Humanities. It describes interdisciplinary evaluation criteria for major water engineering projects (MWEPs) and portrays an application to the Lower Jordan Valley (Middle East) and the Fergana Valley (Central Asia). Both areas are characterised by transboundary conflicts, by challenges due to demographic and climate change and by political and societal pressures. Based on the findings, the book provides recommendations for science and political decisions makers as well as for international financing institutions. In addition, it outlines research gaps from an interdisciplinary perspective. In the past, MWEPs have been used as an instrument to cope with the demands of growing populations and to enhance development progress. Experiences with MWEPs have shown that a purely technical approach has not always brought about the desired results. In many cases, MWEPs have even resulted in negative implications for society and environment. Therefore, improved management strategies and enhanced technologies for a sustainable water resource management system are a prerequisite to meet present and future challenges. And, moreover, the continuous evaluation and optimisation of these measures is, likewise, a must.

DOWNLOAD EBOOKAt COP28 countries recognized that unprecedented adverse climate impacts are increasingly threatening the resilience of agriculture and food systems and ability to produce and access food in the prevailing scenario of mounting hunger, malnutrition, and economic stresses. As a result, over 150 countries have signed the Declaration On Sustainable Agriculture, Resilient Food Sys tems, And Climate Action committing to expedite the integration of agriculture and food systems into climate action and, simultaneously, to mainstream climate action across our policy agendas and actions related to agriculture and food systems (United Nations Framework Convention on Climate Change (UNFCCC), 2023). Currently, there is no concrete framework and approach available at the country level on how to support this integration process. Thus, in this paper, we are proposing a conceptual framework to undertake such an integration analysis of key national level climate change related and agri culture policy documents. Using Tajikistan as a case study, we identify synergies and existing gaps and provide recommendations on strengthening sectoral integration to achieve climate change goals. In the year 2022, 55 percent (402 million) of the people in the world affected by hunger, were living in Asia. During the COVID-19 pandemic, the number of people who could not afford a healthy diet increased globally, and significantly in Asia. Unemployment, high incidence of climate shocks, poverty, income inequality, food price inflation, and the decline in foreign currency re serves have engendered the lack of affordability healthy diet (Food and Agriculture Organization (FAO) et al 2023).

DOWNLOAD EBOOKDue to many challenges (i.e. climate change, energy, water and land shortage, high demands on food, land grabbing, etc.), agriculture production potential is expected to be seriously affected; thus, increasing food insecurity and hunger in many already affected regions (especially in Africa). In this context, sustainable agriculture is highly recommended as an eco-system approach where soil, water, plants, environment and living organisms live in harmony. Innovative technologies and research should be developed to ensure sustainable agriculture and productivity using modern irrigation systems, improved varieties, improved soil quality, etc. In the meantime, the preservation of natural environment should be based on resource conservation technologies and best management practices. Sustainable Agricultural Development, not only raises the serious ethical and social issues underlying these huge environmental problems, but also aims at presenting successful experiences from all over the world in relation with sustainable farming, sustainable management of water and land resources, and innovative processes in livestock production. It also aims at providing inputs to decision making processes and encouraging the transfer of relevant know-how, technologies and expertise to different countries where similar agro-climatic conditions may exist; thus saving precious resources and promoting sustainable agricultural development as a relevant approach to tackle the food security challenge. Finally, this book focuses on the paradigmatic and policy dimensions and call for an innovative approach by analyzing the key themes in a complex and interrelated manner.
