1. OVERVIEW OF THE NATIONALAGRICULTURE SCENARIO - NATIONAL EXTENSION SYSTEMS, SCOPE AND IMPORTANCE

Like in many developing countries, Agriculture Sector being the backbone of the Sri Lankan economy, contributes significantly (11.3 per cent in the year 2007) to the Gross Domestic Products (GDP) and the economic growth by 7.7 per cent (Central Bank of Sri Lanka, 2007). As to the situation in 2007, 80 per cent of country’s population of 20.01 million is rural and 31.3 per cent of the total Sri Lankan work force is employed in Agriculture sector. Nearly 14.6 per cent of the population still depends on the agriculture as the main livelihood. The country’s GDP has been growing at 6.8 per cent per annum (in 2007), though that of agriculture is growing at only 3.3 per cent.

Country as a whole is constituted by 25 administrative districts all of which is encompassed into nine provinces. Of these, nearly four fifths are predominantly agricultural districts with over 60 per cent of the total population living in them. Majority of the population in these districts constitutes the farming community and they, by and large, are the ones who keep the nation feeding. Apart from plantation agriculture which looks after large scale plantation level crops like tea, rubber, coconut along with other crops like cinnamon, pepper, coffee, cloves, nutmeg etc., grown extensively for the export market, almost all other food crops are grown by farmers, majority of who own land plots less than 2 hectares. On the one hand, this makes agriculture mainstay of a major sector of the population and on the other hand they are spread nearly everywhere in the country rather thinly on the ground.

1. INTRODUCTION

This chapter looks at ICTs in Sub-Saharan Africa (SSA), with a focus on several selected countries in the region. Exciting and positive developments are happening throughout SSA Africa in ICTs. For instance, in spite of extensive poverty, SSA has had the fastest growing mobile market in the world over the last five years. The mobile telephone in the region has morphed to serve uniquely African development needs, including those in rural areas. It is being used for market information, extension messages and as virtual currency. In Kenya and Uganda, mobile phone services provide cheap messages about crop price information via text messaging. In Tanzania, there are ‘market spies’, farmers who visit local markets and remain in contact with the village using mobile phones to negotiate for better prices.

In spite of the growing use of mobile telephony and other ICTs, Africa has lagged behind in harnessing ICT potential for extension and other rural development issues in comparison to countries such as China, India, and Chile. Sub-Saharan Africa has the lowest teledensity in the world (Bertolini, 2006a). Many challenges exist to ICT use in SSA, and there are concerns that many rural African communities are being further left behind through the ‘digital divide’.

1. INTRODUCTION

Sudan lays close to the east-centre of Africa between Latitudes 4° and 2° and longitude 22° and 28° east. It is the largest country in African continent (8.3 per cent) and Arab world and the ninth largest in the world (1.75) covering 2.59 million square kilometers of twenty six states (El Mustafa, 2005). It shares borders with Egypt, Libya, Chad, Central Africa, Zaire, Uganda, Kenya and Ethiopia. It is a criterion for absolute continent in terms of the extent and variety of vast agricultural lands, vast agricultural and pastoral country with rich cultural diversity. It homes about forty million people, seventy five per cent of which inhabit rural areas, speaking over a hundred and thirty indigenous languages and dialects. The country is a gentle sloping land with the exception of Jebel Marra Massif, Red Sea hills, Ingessena hills and the Nuba Mountains (Ahmed et al., 2004).

The Nile and its tributaries traverse it for about 900 km. The rainfall ranges from less than 50 mm in the northern desert to more than 1500 mm in the tropical rain forest in the south.

In general, the soils include aridsols (sand dunes and sandy soils), aridisols and vertisols (clay pockets in the valleys) in the North, vertisols in the central and southern clay plains and oxisols in the south. Variations in rainfall, vegetation and soils resulted in the formation of seven main ecological zones classified as follows: desert (0-75 mm, 28.1 per cent,), semi-desert (75-300 mm, 19 per cent), low rainfall savanna on sand (300-400 mm, 26.6 per cent), low rainfall savanna on clay (400-800 mm, 13.3 per cent), high rainfall savanna (800-1300 mm, 9.5 per cent), Montana vegetation region (800-1000 mm, 0.3 per cent) and flood region (800-1000 mm, 3.2 per cent) which embedded in twenty six states.

1. INTRODUCTION

Agricultural Extension in Trinidad and Tobago is searching for a way to effectively use Information Communication Technologies (ICTs) to improve the delivery of services to the farming community. The notion of a demand-driven extension service seems to appeal to the Ministry of Agriculture, and many believe that ICT has the potential to become a primary enabler to improving the extension service.

The country has a population of 1.3 million with one of the highest per capita incomes in Latin American and the Caribbean (US$16,090 in 2007). Oil and gas account for 40 per cent of GDP and 80 per cent of exports. The unemployment rate is 5 per cent, and the labour market is characterized by chronic shortage, high price and low productivity particularly in the agricultural sector (Government of the Republic of Trinidad and Tobago, 2008). One of the government’s objectives is to develop a vibrant agriculture sector to reverse the decline of agriculture. The government’s operational plan 2007-2010 identifies a model for transformation which includes joint ventures with the private sector, investments to develop farms via Government to Government arrangements, and improvements in infrastructure and communication (Republic of Trinidad and Tobago, 2007).

1.1. The Agriculture Sector of Zimbabwe

Zimbabwe has a total area of 390 580 square kilometers of which one per cent is made up of rivers and lakes, 38 per cent is arable land and the rest is suited for livestock and wildlife production. The country is bordered by South Africa, Botswana, Namibia, Zambia and Mozambique. It is located between latitudes 15,30 and 22,30 degrees south of the Equator and between longitudes 25 and 33,10 degrees east of the Greenwich Meridian (CSO, 2006).

The Agriculture sector forms the backbone of Zimbabwe’s economy and accounts for about 17 per cent of the GDP. Zimbabwe‘s agricultural sector comprises mostly smallholder farmers who include communal, resettlement and small-scale farmers. However, this sector is besieged by a plethora of issues, namely high stocking rates, sub-optimal climate, and deforestation and land degradation. The Land Reform and Resettlement Programme which commenced in 1980 resulted in hundreds of thousands of Zimbabweans being resettled on former white commercial farms, in either Model A1(communally owned) or A2 schemes (large scale commercial farms). Thus the challenge to policy makers was now to ensure that future agricultural production is not compromised by current practices. The new farming sector largely comprises resource poor farmers, academics, corporate leaders, high-level policy makers and traditional farmers. Most of the new farmers lack requisite Agricultural skills and knowledge needed in modern Agricultural practice. Land reform measures led to the exodus of some white farmers in the beginning of the 21st century which crippled the economy depriving it of technological know-how and causing shortages of basic commodities.

The modernization of agriculture therefore, among other intervention strategies, through the use of ICTs can contribute directly to food security at national and household levels, beneficiation of agricultural produce, effective land management and an increase of national wealth.

To understand IoT “Internet of Things” it is important to understand internet first. Internet is connecting a device to other device anywhere in the world. When two devices are connected with the Internet, they can send and receive all kinds of information such as text, graphics, voice, and video. The high-speed, fiber-optic cables are used, through which the bulk of the Internet data travels. The Internet has revolutionized the communication world. In today’s scenario the internet is an important part for people around the world. The Internet is a global network of billions of electronic devices. The World Wide Web (www) is most widely used part of the Internet.

The “Internet of Things is a potentially integrated part of the ‘Future Internet’. IoT can be defined as a dynamic global network with self - configuring capabilities based on communication protocols where physical and virtual ‘Things’ interact with each other.

The Internet of Things (IoT) is inter-connecting the networks of smart devices. Smart devices may be embedded with vehicles, buildings, or other electronics object with software, sensors, actuators, and network connectivity.
