Also available in:
No results found.Distribution of water from the supply canal to the individual farm remains the most troublesome feature of irrigation development in the Asian area of smallholder cultivation. This is particularly the case where crops other than paddy are being grown in at least one season of the year, when the simple field-to-field approach which is appropriate only to wet-land paddy is not applicable. The latter is the situation considered in the following notes.

Book (series)Working paperBioenergy and food security (BEFS) assessment – Seychelles 2022
Also available in:
No results found.A sustainable and stable energy supply is essential for a country’s stability and wellbeing. Seychelles, like many small island developing states (SIDS), currently depends on imported energy, in the form of fossil fuels. The high dependence on fossil fuel imports means Seychelles is highly vulnerable to disruptions in global markets. The situation is exacerbated by a reliance on imported food, which accounts for about 70 percent of food consumption. To limit this dependence, it is aiming to increase its reliance on renewable energy to 15 percent by 2030, with a long-term ambition of using 100 percent renewable sources for electricity production. Sustainable bioenergy is one form of renewable energy that can be used to green a country’s energy mix. This Sustainable Bioenergy Assessment report for Seychelles looks at the potential for sustainable bioenergy within the country, considering the country context, conditions and delicate habitat. The report considers sustainable biomass sources from the agriculture, forestry and waste sectors. The assessment was conducted following the bioenergy and food security (BEFS) approach of FAO, and identifies a number of bioenergy pathways relevant for the country. Within the report, the different forms of biomass, their availability and viability are assessed. Livestock, crop and forestry residues, and the biodegradable portion of waste, otherwise destined for landfill, are among the sources of biomass considered. The use of these biomass types and amounts are then assessed from a technical and economic point of view, under different price scenarios, for the production of energy. -

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms.
