Human in nature: two cases on social factors nested in the implementation of Nature-based Solutions

<p>Nature-based Solutions (NbS), inspired or supported by nature, aim to address societal challenges in a fast-changing environment via an integrated and sustainable approach. Effective implementation of such intervention certainly requires compliance with specific societal configurations in different geographies. Here two cases of NbS to hydrological disaster risks are used to demonstrate the relevance of social barriers and opportunities for the full function of NbS.</p><p>Firstly, we introduce a novel large-scale NbS designed for reducing water scarcity in the Bolivian city of Santa Cruz de la Sierra. In this case, strategic reforestation was planned to bring rainfall to a downwind city taking advantage of atmospheric moisture pathways. In the process of co-designing reforestation sites, experiences from failed reforestation projects have improved the site selection originally based solely on the scientific evidence of the moisture pathways. Social barriers to implementation include underground economic activities and pressures for local food production. The latter factor also implies a trade-off between the fulfilments of different sustainable development goals.</p><p>Secondly, a case of landscape-scale NbS that aims to mitigate flood risk from typhoons in Taiwan will be discussed. It consists of a flood diversion framework that directs excess runoff to local farmlands following Typhoon storms. The concept of payment for ecosystem services has been employed to increase the willingness of farmers and landowners to participate in this framework. Institution of compensation for agricultural loss established from previous meteorological disasters has paved the way for implementation. A combination of subsidies and agricultural loss compensation has offered an opportunity for the new intervention to take place in the rice-cropping landscape, while the effect of this ongoing framework will be further documented.</p><p>These two cases show that the inertia from existing policy/institutional schemes and the lessons from past unsuccessful experiences provide an opportunity to identify and overcome social barriers to the implementation of innovative NbS.</p>

Somalia

This paper discusses Somalia’s Second Review Under the Staff-Monitored Program and Request for Three-Year Arrangements Under the Extended Credit and the Extended Fund Facility. The three-year financing package will support the implementation of the authorities’ National Development Plan and anchor reforms between the heavily indebted poor countries Decision and Completion Points. Reforms will focus on a continued strengthening of public finances to meet Somalia’s development needs in a sustainable manner; a deepening of central bank capacity; improvement of the business environment and governance; and enhancing statistics. Risks to the program and outlook remain elevated, although there is also upside potential. The immediate political risks concern the upcoming elections, while frequent climate shocks continue to contribute to agricultural loss and human displacement. On the upside, greater-than-expected impact from reforms under the program and additional development financing, together with the development of new industries, could lead to higher and more inclusive growth than the baseline.

Susceptibility of six corn varieties (Zea maysL.) to Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae)

Agricultural produce is commonly stored in warehouses after the harvest period, before being utilized and fulfilling the crop stock. However, crop threats are not only present during cultivation and harvest, but crops can also be infected during storage, which leads to agricultural loss. This research aimed to observe the resistance level of corn varieties of Bisma, Bisi 18, Bisi 19, Pioneer 21, Pioneer 29, and Pertiwi 3 to the Sitophilus zeamaispest of stored product insects. This resistance was based on the mechanism of non-preference (antixenosis) resistance, measured with the Free Choice Test Method (FCTM), and antibiosis resistance mechanism, measured with the No Choice Test Method (NCTM). The results showed that based on the susceptibility index (Dobie, 1974), corn varieties of Pertiwi 3 were categorized as resistant to S. zeamais pests, while the varieties of Bisi 19, Bisma, Bisi 18, Pioneer 21 and Pioneer 29 were moderately resistant.

The Effects of the 2004 Hurricane Season on Greenhouse Vegetable Production in Florida

The 2004 hurricane season proved to be one of Florida's worst. The four hurricanes (Charley, Francis, Ivan, and Jeanne) caused over $2 billion in total agricultural loss. In response, the federal government appropriated $13 billion for emergency assistance, of which Florida received a half billion dollars for agricultural disaster assistance. Many of Florida's producers were eligible for up to $80,000 in aid. Among those who tried but failed to qualify for this aid were greenhouse vegetable producers. Although the greenhouse vegetable industry in Florida is small, it is expanding and the present growers suffered millions of dollars in damages from the hurricanes in 2004. A survey was conducted in March, 2005 to assess both hurricane damages in 2004 and the present status of the greenhouse vegetable industry in Florida.

Invasive Lantana camara L. Shrub in Ethiopia: Ecology, Threat, and Suggested Management Strategies

Lantana camara L. is one of the worst invasive alien species that are categorized worldwide. The objective of this review paper was to review the dispersal and threats posed by Lantana camara L. in Ethiopia and based on review results, to suggest management strategies that can bring solutions to the threats posed by the weed. Both biological characteristics of Lantana camara L. and its dispersal agents have contributed to the success of its dispersal. Even though Lantana camara L. is dispersed in other places within Ethiopia, Debrezeit, Dire Dawa, Harar and Somali are the hotspot areas for the weed. Biodiversity and potential agricultural loss, human and animal health problems and infestation in national parks are the identified threats that Lantana camara L. posed within the country. Utilization of Lantana camara L. for various purposes, prevention of its further dispersal into non-infected areas, use of fire, mechanical and biological control and awareness creation are the suggested management strategies that can bring solutions to the threats posed by the weed within the country.
