This chapter provides a comparative meta-analysis of several global studies on long-term climatic trends, extreme events and their consequences on the important countries in Asia and Africa. Here we argue that climate-related losses are of greater magnitude than, and inventoried less than, the losses due to climatic extremes and natural disasters. It tries to answer questions such as what do the data indicate for the regions? Comparative assessment and regional trends are reported for: (i) the semi-arid tropics of India; (ii) the Mekong river region and north-east region of Vietnam; (iii) the semi-arid north-east region of Thailand; (iv) the drought and flood plains of Bangladesh; and (v) the dry regions of Sri Lanka.

Pearl millet (Pennisetum glaucum) is the fourth most important cereal in India in terms of area cultivated after rice, wheat, and sorghum. It provides grain and fodder to milch animals and is usually grown under harsh environments and on poor soils. India grows about 7 Mt of pearl millet grain from 10 Mha of land. The major pearl millet-growing states in India are Rajasthan, Maharashtra, Gujarat, Uttar Pradesh, Haryana, Karnataka, Tamil Nadu, Madhya Pradesh and Andhra Pradesh (Table 1). In terms of yield in 1995-98, Uttar Pradesh stood first, followed by Gujarat, Tamil Nadu, Haryana, Madhya Pradesh, Andhra Pradesh, Maharashtra, Karnataka, and Rajasthan. These nine states covered more than 99% of the total pearl millet area and production in 1995-98. While the area under pearl millet has been declining over time in all the states, except Maharashtra, production has gone up in all the states, except Andhra Pradesh and Tamil Nadu (Table 1). Pearl millet yield increased in all the state...

Food legumes play an important and diverse role in the farming systems and in the diets of the poor people around the world and for achieving food and nutritional security in the developing countries. Given the importance of food legumes in the developing countries especially in Asia, the objective of this paper is to assess crop specific trends, distribution and developments in area, production and productivity of three important legumes crops like groundnut, chickpea and pigeonpea and also to provide the plausible futures of these crops under the changing future climate. In this study, a global partial equilibrium multi-commodity trade model was used to assess the future projection of supply, demand, prices and trade of the food legume producing and consuming countries around the world. The study revealed that production has not been able to meet demand due to the secondary treatment of pulses in Asian countries. The projected demand for groundnut, chickpea and pigeonpea in Asia w...

Background: The meso-level dataset for India and Bangladesh contains data pertaining to the performance, structure and dynamics of agricultural economy at country level and its disaggregation at state/region, district, and sub-district level. The dataset maintained by ICRISAT and updated under the Village Dynamics in South Asia (VDSA) Project provides a comprehensive one-stop shop for data related to key agricultural and socioeconomic variables that are relevant for hypotheses testing, identification of regions/ districts for priority setting, and targeted poverty alleviation development initiatives. The meso-data thus acts as a link between the country/state/district level macro/meso-data and household-level micro data (see Figure 1).

Successful development of appropriate improved crop cultivars paves the way for their adoption by farmers. Adoption of improved cultivars is a necessary precondition for plant breeding creating favorable impacts on farm households. Impacts may be obtained through yield increases, quality improvement, reduction in unit cost of production and reduced production risks. This chapter is a compilation of information about the level of adoption of improved sorghum cultivars and factors influencing it. Adoption of improved sorghum cultivars was measured as a percentage of improved sorghum area in the total sorghum area. Based on their origin, adoption levels of improved sorghum cultivars were divided into four groups: (i) percentage of area sown to ICRISAT-bred cultivars; (ii) percentage of area sown to cultivars having ICRISAT parents; (iii) percentage of area sown to ICRISAT network cultivars; and (iv) percentage of area sown to non-ICRISAT (other) cultivars.

The magnitude of changes in average crop production and the sources of changes were measured for six crops- Aus rice, Aman rice, Boro rice , jute, wheat and sugarcane between two time periods pre-modern technology adoption period and modern technology (MT) adoption period. Except for wheat, these periods were defined as 1947/48 -1967/68 and 1968/69- 1986/87 respectively. For wheat, these periods were defined as 1947/48-1971/72 and 1972/73 -1986/87 respectively. The analysis shows that production, area and yield increased at the national level for all the crops except jute. Although area under jute increased, its production and yield declined in the second period. Change in mean area was the main source of mean production change in sugarcane, Aus rice and Boro rice. But yield was the main source of increase in Aman rice production and decrease in jute production. For wheat, interaction between changes in mean area and mean yield was the principal source of change in production. And y...

Sportfishing, also known as recreational fishing, is an economically and culturally important activity in the U.S. Baitfish are used by sportfish enthusiasts who prefer live bait over artificial lures or attractants. About two-thirds of the total baitfish and more than one-third of the sportfish sold in the country originate from Arkansas. This paper has systematically collated and synthesized information, data, and insights from multiple sources and publications. It has analyzed the trends in baitfish and sportfish production (sales) and sportfishing in Arkansas. Additionally, it has reported the impacts of sportfishing on the state economy. Between 2013 and 2018, the number of baitfish farms increased both in Arkansas and the U.S. During this period, the value of baitfish sales increased by 20.7% in Arkansas and 11.6% at the national level. Between 2013 and 2018, the number of sportfish farms decreased both in Arkansas and the U.S., but the value of sportfish sales increased by 87.6% in Arkansas and 65.0% at the national level. A total of 662,900 anglers participated in recreational fishing in Arkansas in 2018. They spent $786.4 million, supported 9,510 jobs, and contributed $1.2 billion in economic output to Arkansas in 2018 (ASA, 2021). Sportfishing and related activities have increased in Arkansas during the COVID-19 pandemic. The Arkansas Game and Fish Commission's (AGFC) proactive promotional campaign, timely policies, and guidelines for safe and socially distanced fishing protocols increased recreational fishing in Arkansas during the pandemic. The study argued that, among other factors, Arkansas-certified baitfish has substantially contributed to the growth of the baitfish industry over the years. The study concluded that the sportfishing industry in Arkansas deserves the necessary support from policymakers, government and other stakeholders.

Live ornamental fish is a valuable export item for the USA. In 2018, the USA exported ornamental fish worth 9.92 million dollars to 45 countries and territories. This study has analyzed trends in ornamental fish exports and identified countries where the USA had revealed comparative advantage (RCA) in ornamental fish export. Analysis based on the data collected from the USDA-Economics Research Service showed that the value of ornamental fish exported by the USA has increased from $6.93 million in 2001 to $9.92 million in 2018. Major export destinations in 2018 were Canada (35.87 % of total export), China (15.72%), Hong Kong (10.54%), Brazil (6.25%), the United Kingdom (5.09%), the Netherlands (4.62%), Taiwan (3.81%), Japan (3.28%), Germany (3.16%) and Italy (1.34%). Results showed that the USA had revealed comparative advantage (RCA) in the export of ornamental fish to Canada, Japan, and the United Kingdom in all the study years (2001-2018) and for Hong Kong in all years except 2007. The USA had revealed comparative disadvantage (RCD) in export to Italy, mixed (RCA in some years and RCD in other years) in China, Brazil,

This study analyzes the trends and determines the comparative advantage and competitiveness of India's fish and fishery products trade in the world market and of India's exports to 10 major destinations over the period of 2000-2021. We use the revealed symmetric comparative advantage (RSCA) index to quantify India's comparative advantage in exporting fish and fishery products and the Vollrath index to measure the revealed competitiveness of the country's fish and fishery products trade. We collected relevant data at Harmonized System (HS) four-digit level from the UN Commodity Trade (UN Comtrade) database. Our analysis shows that India has a revealed comparative advantage (RCA) in exporting fish and fishery products to the world market. Specifically, India has a comparative advantage in exporting frozen fish, crustaceans, and mollusks; but it has a comparative disadvantage in exporting live fish, fresh and chilled fish, fish fillets and other fish meat, and dried/salted/in-brine and smoked fish to the world market. In terms of individual destinations, India has RCA in exporting live fish to Hong Kong; fresh and chilled fish to UAE (in recent years); frozen fish to China, Hong Kong, Thailand (recent years), and Vietnam (recent years); fish fillets and other fish meat to Japan (recent years); dried fish to Hong Kong; crustaceans to Japan, the US, and Canada (recent years); mollusks to the EU, Thailand (recent years), and Vietnam (recent years); and other aquatic invertebrates to Vietnam. India has a comparative disadvantage (RCD) in exporting fresh and chilled fish to the EU, Japan, the US, and Vietnam, and fish fillet and other fish meat to the US, Canada, and Vietnam. The COVID-19 pandemic has negatively affected India's export, comparative advantage, and trade competitiveness of fish and fishery products. India's RCA and competitiveness in exporting fish and fishery products decreased in 2018-2020, but the RCA and competitiveness increased by 2021.

The present study has analyzed the trends in export and revealed comparative advantage (RCA) in the export of major aquaculture products by the U.S. for the last 22 years (1997 to 2018). Relevant export data were obtained from the U.S. Department of Agriculture Economic Research Service. Balassa index was used to measure RCA for major aquaculture products exported by the U.S.

Between 1997 and 2018, the value of the total export of aquaculture products has been more than doubled, increasing from $.66 billion in 1997 to $1.36 billion in 2018. The export value of all aquaculture products except three (ornamental fish, canned and prepared salmon, and live trout) has increased. The export value of these products has declined. Major destinations for aquaculture products exported by the U.S. were Canada, China, Japan, the European Union (EU), and South Korea. In 2018, these countries and regions accounted for 78% of the total exports of major aquaculture products by the U.S. The study showed that the U.S. had RCA in the export of salmon (canned and prepared) to the EU; for Atlantic salmon (fresh), ornamental fish, oysters, Pacific salmon (fresh), and trout (fresh and frozen) to Canada; for Pacific salmon (frozen) to China and Japan; and for Atlantic salmon (frozen) to South Korea. Finally, the study has articulated the implications of the research results for further promotion of aquaculture export from the U.S.

The Aquaculture and Fisheries Center of the UAPB, in collaboration with the Food Processing and Sensory Quality Research Unit of the USDA-ARS Southern Regional Research Center in New Orleans, Louisiana, and Texas State University, implemented a project entitled “Designing and Testing New Catfish Products to Enhance Competitiveness of the U.S. Catfish Industry”, funded by USDA-NIFA.  The project has developed five convenient (ready-to-cook) catfish products. These catfish products are Panko Breaded Standard Strips (PBSS), Panko Breaded Standard Fillet (PBSF), Panko Breaded Delacata Fillet (PBDF), Sriracha Marinated Delacata Fillet (SMDF) and Sesame-Ginger Marinated Delacata Fillet (SGMDF). Panko breaded products are ready-to-bake products, and marinated products are ready-to-microwave products.  This paper documents the process for the development of convenient catfish products, describes the sensory attributes of the products, and reports findings of consumers’ evaluation tests. Consumers' evaluation included feedback about the products’ visual (appearance, color, glossiness, and serving size) and organoleptic (smell, taste, texture, smell intensity, saltiness, oiliness, crispiness, and juiciness) sensory attributes. It has also analyzed consumers’ willingness to pay (WTP) for the convenient catfish products.  Analyses revealed that participants accepted all the products. Breaded (ready-to-bake) products received a higher acceptance rating than marinated (ready-to-microwave) products. PBDF was the most preferred product, followed by PBSS, PBSF, SMDF, and SGMDF. Consumers’ WTP was higher for breaded products than marinated products. Sensory attributes influenced consumers’ preference and their WTP.  The study concluded that all the newly developed convenient catfish products are likely to be purchased by American consumers when they would be available in the market.

The Tropical Legumes II (TL-II) project, funded by the BMGF, aims to improve the lives and livelihoods of smallholder farmers in the drought-prone areas of sub-Saharan Africa (SSA) and South Asia through improved productivity and production of six major tropical legumes – chickpea, common bean, cowpea, groundnut, pigeonpea and soybean. It has been implemented in ten target countries that included in WCA, ESA and SA regions in two phases (Phase 1: 2007-08 to 2010-11; Phase-2: 2011-2014). But, the present paper discusses about only three legumes (chickpea, pigeonpea and groundnut) crops and the interventions carried out in India only. Specifically, this initiative has been focusing on proper targeting for development of improved cultivars of food legumes, promotion of their adoption, proactive public sector policies and finally linking these small holders to markets and value chains. A number of studies have been completed in six states (Andhra Pradesh, Maharashtra, Bihar, Karnataka, ...

Black soldier fly (Hermetia illucens) larvae (BSFL) production is increasing, which will leaves substantial amounts of leftover excrement, called ‘frass’ that may be a beneficial organic fertilizer. In this study, sweetpotato (SP) (Ipomoea batatas) cuttings (‘slips’), were grown with BSFL frass as a one-time top dressing at either 333.7g/m2 or 667.4g/m2, respectively, or daily applications of either BSFL frass tea (225g in 3.78 L) or an inorganic fertilizer (control). The nitrogen-phosphorus-potassium of the BSFL frass and inorganic fertilizer was 6.2-1.4-1.7 and 10-30-20, respectively. After three weeks, no significant difference in length, number of nodes and stem diameter were found in the 667 g/m2 frass treatment versus control, while these values were significantly lowest in the frass tea treatment. Slip manganese and copper were significantly lower and higher, respectively, in the control compared to the 333 and 667 g/m2 frass treatments. Iron, copper, manganese, zinc and magn...

Chickpea, Pigeonpea and Groundnut are the most important food legumes in South Asia. They are integral part of semi-arid tropics (SAT) cropping systems and farmers’ livelihoods. Besides enriching soil fertility, food legumes also provide substantial income to the farm households and also contribute significantly towards household nutritional security. Since 2007, ICRISAT along with partners from National Agricultural Research System (NARS) in India and Bangladesh have been implementing ‘Tropical Legumes-II’ project supported by Bill & Melinda Gates Foundation (BMGF) for increasing the production and availability of legumes particularly for small holder farmers’ and poor consumers in South Asia. Specifically, the major objectives of this initiative has been focusing on proper targeting and development of legume improved cultivars, promotion of their adoption, advocacy of proactive public sector policies and finally linking these small holders to markets and value chains.

Increased importance of rural non-farm economy (RNFE) to the livelihoods of rural population has been reported in recent studies. The RNFE includes all income generating activities (either as a paid work or as self-employment) that are not agricultural but provide income to the rural households. The RNFE is of great importance to the rural economy for its productive and employment effects as well as for creating demands for agricultural commodities. This paper has documented the occupational patterns among rural households in semi-arid tropics (SAT) of India. It has identified various types of rural non-farm (RNF) activities and quantified the contribution of various RNF activities to employment and household income. We have studied participation behaviours of household members in non-farm employment and factors affecting the RNF activities. The study is based on household level panel data collected by ICRISAT under the Village Dynamics Studies in south Asia (VDSA) project. A total ...

Rural households in many countries have used temporary or seasonal migration as a strategy to cope with natural shocks such as drought, means of employment and income generation during lean season and to move out of poverty. This paper studies the linkages between migration, employment in economic activities, asset accumulation and poverty reduction among rural households in a drought-prone village of India over the last four decades. The Dokur village of Mahbubnagar district in Telangana State of India experienced persistent drought over a decade. To cope with this situation, many households of the village temporarily migrated to the nearby and faraway cities. ICRISAT had conducted household surveys in Dokur under the Village Level Studies (VLS) and Village Dynamics Studies (VDSA) program since 1975. The present study has used the VLS-VDS dataset (1975-2012) and reorganized sample households into 46 dynasty households. Based on their participation in migration, sample households we...
