No results found.The climate smart agriculture (CSA) concept reflects an ambition to improve the integration of agriculture development and climate responsiveness. It aims to achieve food security and broader development goals under a changing climate and increasing food demand. CSA initiatives sustainably increase productivity, enhance resilience, and reduce/remove greenhouse gases (GHGs), and require planning to address trade-offs and synergies between three pillars: productivity, adaptation and mitigation. The priorities of different countries and stakeholders are reflected to achieve more efficient, effective, and equitable food systems that address challenges in environment, social, and economic dimensions across productive landscapes. The country profile provides a snapshot of a developing baseline created to initiate discussion, both within countries and globally, about entry points for investing in CSA at scale. Seychelles is a small island state in the western Indian Ocean, which has developed a high-income economy and eliminated extreme poverty. Agriculture contributes about 2.2% of the country’s gross domestic product with tourism and the fisheries and seafood industries serving as the main pillars of the economy. Agricultural land occupies about 3.4% of the total land area of the country. A large portion of the land area (88.4%) is covered by forest mainly natural and established plantations for commercial purposes. Seychelles is divided into two large agro-climatic zones based on biophysical characteristics- mountainous/forest zone high ground and coastal plateau. In terms of agriculture, two agroecological zones can be distinguished mainly based on soil: upland and sandy soil. Main cropping systems includes food crop-based systems and perennial crop-based systems. Livestock production include goat, pig and chicken. Most crop production is under rainfed or irrigation system. Most farms are under 2 ha with backyard farming done to supplement household food or income. The main crops and products include coconut, cinnamon, vanilla, sweet potato, cassava, banana and tuna. Seychelles has the highest rate of overweight and obesity in Africa due to the shift from predominantly unprocessed traditional foods to a more westernised dietary intake consisting mainly of refined and processed foods. most greenhouse gas (GHG) emission come from the energy sector, followed by waste and agriculture which contributes 0.79% of the total. Seychelles has outlined in its nationally determined contributions mitigation actions in the forestry, energy and transport, and waste sectors. In agriculture, actions to mitigate climate change include: promotion of agricultural practises such as agroforestry which would involve mainstreaming strategies to limit deforestation and increase the sink capacity of forests. Challenges for the agricultural sector include (i) deforestation and unsuccessful intensification, (ii) uncontrolled urbanisation, land clearing, bush fires and population pressure, and (iii) high reliance on food imports. Agriculture in Seychelles is limited by a lack of arable land and extreme rainfall patterns and meteorological events like tropical storms, floods and droughts. Climate change poses serious challenges to the country such as uncontrolled economic and social consequences of floods, land degradation, sea-level rise, coastal erosion, declining agricultural yields, health vulnerability, and increased occurrence of drought. CSA technologies and practises present opportunities for addressing climate change challenges as well as for economic growth and development of the agriculture sector. Identified CSA practises in use in the country include: crop production under shade houses, inter cropping, use of organic manure and mulch, use of weather information, water control through irrigation, anti-erosion arrangement, windbreak and shelter, and use of climate-adapted seeds. Seychelles has several key institutions and policies aimed at supporting and increasing agriculture productivity and advancing CSA practises. These include government ministries and agency structures of ministries, firms operating in the agricultural sector, academic institutions, specialised laboratories and agricultural research institutes and training centres. The Ministry of Environment, Energy and Climate Change (MEECC) serving as the country’s UNFCCC focal point and nationally designated authority to the Green Climate Fund is responsible for country’s climate change plans and policies. On the agriculture front the ministry of agriculture and fisheries is the key government institution for partnerships for climate-smart agriculture work in the communities as well as for policy and investment related issues through the national agricultural investment plan. A number of csa-related policies and strategies have been developed: National Programme on climate change strategy, national strategy for disaster risk management, national biodiversity strategy and action plan and the mainstreaming of climate change adaptation into the country’s strategic plan- a definitive document intended to guide land-use management up to the year 2040. A number of projects that foster the development of knowledge and evidence on the effectiveness of climate smart agriculture in improving food security, mitigating climate change and improving the adaptive capacities of production systems and populations in Seychelles have received support from various donors and financing schemes. In addition, AfDB, COMESA, FAO, EU, IFAD, etc. have invested hugely in several aspects of the climate/agricultural sector of Seychelles which also include the development and promotion of csa innovations. From various sources of climate finance available internationally, Seychelles is currently eligible for only a limited number of these and has not wholly accessed major funding instruments such as the Green Climate Fund and Adaptation Fund. The county is a small island nation whose prospects rely heavily on external demand, especially tourism. This poses major challenges for diversification and resilience. Its commitment to csa is relatively new with limited institutions and sources of funding. -

No results found.The climate smart agriculture (CSA) concept reflects an ambition to improve the integration of agriculture development and climate responsiveness. It aims to achieve food security and broader development goals under a changing climate and increasing food demand. CSA initiatives sustainably increase productivity, enhance resilience, and reduce/remove greenhouse gases (GHGs), and require planning to address trade-offs and synergies between three pillars: productivity, adaptation and mitigation. The priorities of different countries and stakeholders are reflected to achieve more efficient, effective, and equitable food systems that address challenges in environment, social, and economic dimensions across productive landscapes. The country profile provides a snapshot of a developing baseline created to initiate discussion, both within countries and globally, about entry points for investing in CSA at scale. The agricultural sector is the main stay of the economy of Guinea-Bissau. In the absence of other resources, the sector despite being underdeveloped plays a leading role in supporting food security and job creation. Presently it contributes about 46% of national gross domestic product (GDP) with 84% of the population actively employed in primary production agriculture largely dominated by women. The majority of these farmer are small scale farmers farming on less than two hectare (2 ha). More than half (58%) of the total land in Guinea-Bissau is used for agriculture with area under forest heavily degraded by rapid exploitation. However, there are huge potentials for agricultural and forestry land including arable land estimated at about 1.5 million hectares. Farmers engage in the production of diverse crops and livestock such as cashew, rice (country’s staple food), sorghum, maize, etc largely cultivated by subsistence farmers. Women usually take up horticulture in the urban areas. Livestock production concentrated mainly in the north and east of the country is one of the main economic activities supporting food security and thousands of livelihoods. The country is divided into three agroecological zones based on ecological, climatic and demographic characteristics. Agriculture is mainly rainfed with very limited irrigated farming practised. About 82% of water withdrawn is used for agricultural purposes impelling a necessity for huge investments in irrigation to support agriculture production. The projected population growth and food demand is expected to have serious implications on food security with a potential to affect the agricultural sector. Despite the agro-forestry-pastoral potential and fisheries resources of Guinea-Bissau, many studies have shown that, the current food situation in the country is very precarious with poverty identified as the underlining cause. Greenhouse gas (GHG) emission from the agricultural sector has been identified as very high with the country indicating reforestation as the major action for mitigating GHG emissions in its nationally determined contribution (NDC). Some challenges for the agricultural sector identified include (i) growth in population and food demand, (ii) land use change and natural resource depletion, (iii) limited marketing opportunities of agricultural commodities, and (iv) climate change and variability. Guinea-Bissau has a typical hot, humid monsoon-like tropical climate with two well-defined seasons. Agriculture is exposed to the effects of climate change with the country vulnerable to droughts, floods and sea level rise. The projected changes in temperature and rainfall are expected to have substantial impact on water resources which are already limited in their capacity to provide sufficient water for the agriculture sector. CSA technologies and practises present opportunities for addressing climate change challenges as well as for economic growth and development of the agriculture sector. Identified CSA practises in use in the country include (i) use of organic manure, (ii) use of weather information, (iii) water supply through drip irrigation, (iv) anti-erosion arrangement, (v) forage/fodder production, (vi) crop rotation, and (vii) rainwater harvesting through the Zai technique. There are a number of institutions and policies aimed at supporting and increasing agriculture productivity and advancing CSA practises in Guinea-Bissau. These include government, private sector, the national institute for agrarian research and general directorate of rural engineering with each most of the institutions profiles having CSA-related activities that deliver on all three pillars of CSA. The Ministry of environment which serves as the country’s UNFCCC focal point and Nationally Designated Authority to the Green Climate Fund (GCF), Adaptation fund, Climate Investment Fund and Global Environment Facility is responsible for the country’s climate change plans and policies. The food and agriculture organisation of the United Nations, the United Nations development programme and the international union for conservation of nature play instrumental roles in the promotion of sustainable agriculture and environmental sustainability. Most of the climate change and CSA-related funding have come from international sources with the UNDP being of great support through its signature programmes. -
ArticleA comprehensive quantification of global nitrous oxide sources and sinks
Nature, published on 07 October 2020, Volume 586, pages 248–256
2020Also available in:
No results found.Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change2, with the current rate of increase estimated at 2 per cent per decade. Existing national inventories do not provide a full picture of N2O emissions, owing to their omission of natural sources and limitations in methodology for attributing anthropogenic sources. Here we present a global N2O inventory that incorporates both natural and anthropogenic sources and accounts for the interaction between nitrogen additions and the biochemical processes that control N2O emissions. We use bottom-up (inventory, statistical extrapolation of flux measurements, process based land and ocean modelling) and top-down (atmospheric inversion) approaches to provide a comprehensive quantification of global N2O sources and sinks resulting from 21 natural and human sectors between 1980 and 2016. Global N2O emissions were 17.0 (minimum–maximum estimates: 12.2–23.5) teragrams of nitrogen per year (bottom-up) and 16.9 (15.9–17.7) teragrams of nitrogen per year (top-down) between 2007 and 2016. Global human-induced emissions, which are dominated by nitrogen additions to croplands, increased by 30% over the past four decades to 7.3 (4.2–11.4) teragrams of nitrogen per year. This increase was mainly responsible for the growth in the atmospheric burden. Our findings point to growing N2O emissions in emerging economies—particularly Brazil, China and India. Analysis of process-based model estimates reveals an emerging N2O–climate feedback resulting from interactions between nitrogen additions and climate change. The recent growth in N2O emissions exceeds some of the highest projected emission scenarios3,4, underscoring the urgency to mitigate N2O emissions.
