This book was released on 2013-08-05 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: If not addressed in time, climate change is expected to exacerbate Nigeria’s current vulnerability to weather swings and limit its ability to achieve and sustain the objectives of Vision 20:2020 [as defined in http://www.npc.gov.ng /home/doc.aspx?mCatID=68253]. The likely impacts include: • A long-term reduction in crop yields of 20–30 percent • Declining productivity of livestock, with adverse consequences on livelihoods • Increase in food imports (up to 40 percent for rice long term) • Worsening prospects for food security, particularly in the north and the southwest • A long-term decline in GDP of up to 4.5 percent The impacts may be worse if the economy diversifies away from agriculture more slowly than Vision 20:2020 anticipates, or if there is too little irrigation to counter the effects of rising temperatures on rain-fed yields. Equally important, investment decisions made on the basis of historical climate may be wrong: projects ignoring climate change might be either under- or over-designed, with losses (in terms of excess capital costs or foregone revenues) of 20–40 percent of initial capital in the case of irrigation or hydropower. Fortunately, there is a range of technological and management options that make sense, both to better handle current climate variability and to build resilience against a harsher climate: • By 2020 sustainable land management practices applied to 1 million hectares can offset most of the expected shorter-term yield decline; gradual extension of these practices to 50 percent of cropland, possibly combined with extra irrigation, can also counter-balance longer-term climate change impacts. • Climate-smart planning and design of irrigation and hydropower can more than halve the risks and related costs of making the wrong investment decision. The Federal Government could consider 10 short-term priority responses to build resilience to both current climate variability and future change through actions to improve climate governance across sectors, research and extension in agriculture, hydro-meteorological systems; integration of climate factors into the design of irrigation and hydropower projects, and mainstreaming climate concerns into priority programs, such as the Agriculture Transformation Agenda.

Download or read book Abiotic Stresses in Agroecology A Challenge for Whole Plant Physiology written by Mauro Centritto and published by Frontiers Media SA. This book was released on 2017-07-04 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry. Besides increasing carbon dioxide concentration and rising global temperature, increasingly frequent and severe climatic events (e.g. extended droughts, heat waves, flooding) are expected in the coming decades. Additionally, pollution (e.g. heavy metals, gaseous pollutants such as ozone or sulfur dioxide) is an important factor in many regions, decreasing plant productivity and product quality. This Research topic focuses on stress responses at the level of whole plants, addressing biomass-related processes (development of the root system, root respiration/fermentation, leaf expansion, stomatal regulation, photosynthetic capacity, leaf senescence, yield) and interactions between organs (transport via xylem and phloem, long-distance signaling and secondary metabolites). Comparisons between species and between varieties of the same species are helpful to evaluate the potential for species selection and genetic improvement. This research topic is focused on the following abiotic stresses and interactions between them: - Increased carbon dioxide concentration in ambient air is an important parameter influenced by global change and affects photosynthesis, stomatal regulation, plant growth and finally yield. - Elevated temperature: both the steady rise in average temperature and extreme events of shorter duration (heat waves) must be considered in the context of alterations in carbon balance through increased photorespiration, decreased Rubisco activation and carboxylation efficiency, damage to photosynthetic apparatus, as well as loss of water via transpiration and stomatal sensitivity. - Low temperatures (late frosts, prolonged cold phases, freezing temperature) can decrease overwintering survival rates, productivity of crop plants and species composition in meadows. - Water availability: More frequent, severe and extended drought periods have been predicted by climate change models. The timing and duration of a drought period is crucial to determining plant responses, particularly if the drought event coincides with an increase in temperature. Drought causes stomatal closure, decreasing the cooling potential of transpiration and potentially leading to thermal stress as leaf temperature rises. Waterlogging may become also more relevant during the next decades and is especially important for seedlings and young plants. It is not the presence of water itself that causes the stress, but the exclusion of oxygen from the soil which causes a decrease in respiration and an increase in fermentation rates followed by a period of potential oxidative stress as water recedes. - Salinity: high salt concentration in soil influences soil water potential, the water status of the plant and hence affects productivity. Salt tolerance will become an important trait driven by increased competition for land and the need to exploit marginal lands.Understanding plant responses to abiotic stresses is central to our ability to predict the impact of global change and environmental pollution on the production of food, feed and forestry.

This book was released on 2023-10-31 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands and grassland are important components of natural ecosystems, which have rich values in maintaining ecological balance, regional economy and human development. Wetlands can provide freshwater resources and food sources for human beings, purify the water environment and mitigate climate change. The grassland ecosystem has such ecological functions as windbreak, sand fixation, soil preservation, climate regulation, air purification, water conservation and so on, which are closely related to human survival and well-being. In recent years, climate change and human activities have caused a profound impact on the structure and function of wetland and grassland ecosystems, and the problems of decline in size and function have attracted extensive attention from researchers globally. However, there are still many uncertainties about the variety of wetland and grassland ecosystem composition, structure and dynamics, as well as how they respond and adapt to climate change and human activities.
Download or read book Realization of Ecological Product Value Land Use Change and Environment written by Hualin Xie and published by Frontiers Media SA. This book was released on 2024-04-15 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Establishing the mechanism of realizing the value of ecological product is an important way to realize land use change, agricultural production transformation and reduce environmental pollution. In recent years, consumers' demand for ecological products has been increasing while the supply is seriously insufficient. The realization of ecological product value faces various bottlenecks, including the realization mechanism of ecological product value, land use variation and the temporal dynamics of land use change, and the driving forces behind land dynamics and their socio-ecological feedbacks. Meanwhile, the relationship between the realization of ecological product value, land use transformation and changes in agricultural production mode are still unclear. In the process of realizing the value of ecological products, how to realize agricultural production and land use transformation, and environmental improvement is also a constant concern to be solved desperately.
Download or read book Agriculture in Semi Arid Environments written by A.E. Hall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.
