Methodology for methane emission reduction by adjusted water management practice in rice cultivation

декабря, 2022
Global

The methodology is applicable to measures that reduce anaerobic decomposition of organic matter in rice-cropping soils. Such measures include changing the water regime during the cultivation period from continuously to intermittently flooded conditions and/or a shortened period of flooded conditions, using the alternate wetting and drying method, adopting aerobic rice cultivation methods, and switching from transplanted to direct-seeded rice (DSR). This methodology can be applied to large and small-scale or micro-scale projects or PoAs.

Conclusions and recommendations

декабря, 2022
Global

This chapter reviews some of the book’s overarching themes and main findings. Overarching themes include the recognition of persistent hardship and inequality, particularly in the Afghan portions of the basins and substantial knowledge gaps that need to be filled to address existing challenges. Key threads relate to trends in demography, climate, land and water use, and institutions that may accentuate challenges. The chapter concludes that more than incremental change will be needed to support the progress necessary to provide a basic level of human development.

Land and water use

декабря, 2022
Global

Two remote-sensing datasets were used to estimate land and water use in the Kabul, Kurram and Gomal transboundary basins shared between Afghanistan and Pakistan. The proportion of different land-cover classes within these three basins was estimated. Barren land and rangeland form the largest block of land-cover classes owing to the prevailing semi-arid conditions. Domestic water use ranges from 21.2 million m3 (mcm) in Gomal to 554 mcm in Kabul and 106 mcm in the Kurram. Due to the lack of data, industrial water use was assumed to be one quarter of domestic water use.

Chapter 9: Climate Change 2022: Impacts, Adaptation and Vulnerability Contribution of Working Group II to the IPCC Sixth Assessment Report

United States of America

Africa is one of the lowest contributors to greenhouse gas emissions causing climate change, yet key development sectors
have already experienced widespread losses and damages attributable to human-induced climate change, including biodiversity loss, water shortages, reduced food production, loss of lives and reduced economic growth (high confidence).

Best management practices for commercial tilapia reproduction in Northeast Africa

декабря, 2022

Tilapia hatcheries are the most common type of fish hatchery in Egypt, as well as many other countries
globally. Their success has helped supply fish farms with quality tilapia seed, which in turn has increased
farmed fish production in many parts of the world. With the fish farming industry growing so quickly,
however, tilapia hatcheries must improve the quality of their seed production for fish farmers to maintain
their profit margins.
To this end, these guidelines document the most optimal, locally appropriate, management practices for

Smart-Valleys toolkit: An e-learning tool for the sustainable use of inland valleys for agricultural development and biodiversity and ecosystem services preservation

декабря, 2022
Global

Increased reliance on fertilizers and pesticides in rice production has proven unsustainable and ineffective due to soil depletion and pesticide-induced pest outbreaks, rising fertilizer costs, and the negative effects of pesticide and fertilizer use on human health and the environment. The integrated rice-fish system offers a large range of environmental, economic, and social benefits by improving diversification, intensification, profitability, and sustainability through the complementary utilization of land and water uses.

Systems thinking is needed to address the global water crisis

декабря, 2022
France

We are pleased to report that NEXUS Gains has made substantial progress since its launch in April 2022, as outlined in our annual technical report. Energy, food production, and ecosystems are driven by water, which is central to our nexus approach. To ensure the sustainability of the program, we have invested considerable time in building teams and partnerships in our target basins. We have also made substantial progress in building water–energy–food–environment (WEFE) knowledge and capacities, and women’s leadership capacities.

Technical Guideline: Rice Cultivation Reduces Costs, Improves Efficiency, Adapts to Climate Change in the Red River Delta

декабря, 2022
Global

The Department of Crop Production coordinated with the International Rice Research Institute in Vietnam to develop this technical guideline for rice-producing provinces in the Red River Delta. The guideline focused on reducing inputs, improving efficiency, reducing greenhouse gas emissions and adapting to climate change for rice production.

Effects of mid-season drainage on iron toxicity, rice yield, and water productivity in irrigated systems in the derived savannah agroecological zone of West Africa

декабря, 2022

Context: Increasing rice yield is crucial for meeting the demand of the fast-growing population in sub-Saharan Africa. Mid-season drainage can reduce iron toxicity, which is one of the major constraints to rice production in this region, and increase rice yield and water productivity. Objectives: The objectives of this study were to evaluate the effects of mid-season drainage on iron toxicity, rice yield, and water productivity and identify the factors that favor rice yield in the fields with mid-season drainage relative to continuous flooding.

Fragility, Conflict, and Migration

United States of America

Fragility, Conflict, and Migration addresses challenges to livelihood, food, and climate security faced by some of the most vulnerable populations worldwide. The Initiative focuses on building climate resilience, promoting gender equity, and fostering social inclusion. It forms part of CGIAR’s new Research Portfolio, delivering science and innovation to transform food, land, and water systems in a climate crisis.
