1. Basic Information and Agrarian Status

Zimbabwe is a landlocked country located in Southern Africa covering 39,037,000 hectares. It is bordered by Zambia, Mozambique, South Africa, Botswana and Namibia. It is situated between 15 and 22° south latitude and 26 and 34° east longitude. Climatic conditions are largely sub-tropical with one rainy season between November and March. In 1981, the country had 5 hectares per capita whilst it is estimated that the current population to land ratio has declined to 3.25 hectares per person and this is largely attributed to population increases that have taken place over the years. The national census conducted by the Central Statistics Office in 2002 showed that the country has a population of 1,20,00,000 people. About 80 per cent of the population resides in the rural areas, where they sustain their livelihoods through agriculture. When discussing agricultural production activities in the country, it is important to note that nearly all the soils (80 per cent) in the country are sandy from granite rocks or from schists.

1. Country Profile
 
Trinidad & Tobago comprises two islands with Trinidad being by far the larger of the two. They have a combined land area of 5,130 sq. km with Trinidad being 4,825 square kilometer. Over 95 per cent of the population of 1.3 million lives in Trinidad. Tobago’s affairs are, for the most part, administered separately through the Tobago House of Assembly, and therefore, the description of it’s extension system is reported separately.

The CSO report (CSO, 2004) listed Trinidad as having approximately 18,142 farmers who are mostly male (85 per cent) and average age of 52 years. These farmers farm on 84,900 hectares of arable land. The majority of this land (72.5 per cent) is under crop cultivation. While most of this land is dedicated to Sugarcane production, tree crops and vegetable cultivation are also important commodities. The rest of the farmland is used for Livestock (10.6 per cent), mixed farming (16.3 per cent) and some small amount of fisheries production. The majority of farms (63 per cent) are less than 5 hectare in size with 22  per cent being less than 0.5 hectare. Agriculture is mainly rain- fed but increasing amounts of farmland are being irrigated. Trinidad has six months of dry season (January-June) and an annual rainfall of 2010.9 mm of rain.

1. Basic Information

Philippines  is located between 4o23’N and 21o25’N latitude, and between 116oE and 127oE longitude. It is an archipelago of 7,107 islands with three major groups of islands: Luzon, Visayas and Mindanao. It is bounded by the Bashi Channel up north, Sulu and Celebes Seas in the south, the Pacific Ocean to its east, and the South China Sea to its west. The Philippines has a tropical climate with an average temperature range of 23° to 32°C. Populated by 88 million people, the country has a total land area of 3,00,000 square kilometers  (30 million hectares); where about one third is agricultural land (NSO, 2007).

Of the agricultural land, 31 per cent is used for cereals such as corn and rice, 52 per cent for food crops and 17 per cent for non-food crops (ITC, 2007). Majority of these are cultivated on small farms averaging about two hectares and are managed by single families ranging from subsistence to commercial production (NSCB, 2007).

1. Brief Basic Information on Country and Agrarian Status

Peru is the third largest country in South America with 1,285,215 square-meters and in general, there are three well defined regions: the Coast (11 per cent of the territory), the highlands (30 per cent of the territory) and the jungle (59 per cent of the territory). Peru is characterized by the high variability of agro-ecosystems ranging from Deserts in the Coast, lowlands, hills, high mountains, and rainforest in the Jungle. Each region has different agro-climatic conditions, infrastructure and enterprise development. The total cultivable land area is 54,76,977 hectares that is equivalent to 4.3 per cent of the national territory. The coast has 8,70,200 hectares of irrigated land (no rain-fed land because of lack of rain in the coast) and has the best conditions for cultivation of export crops. The highlands have 28,33,800 hectares of cultivable land, 70 per cent of them is under rain-fed condition and the total of the 17,73,000 hectares of cultivated land under rain-fed conditions1 . Land property has undergone a process of changes in the last 40 years.

1. Introduction to Nepal and its Agriculture

1.1. Geography

Nepal is a country of enormous geographical diversity, and is situated in the southern slopes of the central Himalayas, which spreads over an area of 1,47,181 square kilometers. Sandwiched between India on three sides- east, west, and south – and China to the North, Nepal is a land-locked country (CBS,2003).
 
Geographically, the country is broadly divided into five roughly parallel east-west regions (ecological belts), which from north to south are known as High Mountains, Mountains, Hills, Siwaliks  and Tarai. With altitudes ranging from less than 100 m in the Tarai to 8,848 m in the High Mountains, there exist different climates and different types of farming systems within Nepal. As a result of these diversities, a wide variety of crops, vegetables and fruits are produced.
 
For administrative and developmental purposes, Nepal is divided  into 75 districts. Each district is further divided into Village Development Committees (VDCs) in rural areas and municipalities in urban areas. At present, there are 3,913 VDCs and 58 municipalities in Nepal.

1. Country Background

Mozambique is a country that is extremely dependent on agriculture, both for rural livelihoods and for overall economic growth. This importance is illustrated by the following:
    •    The agriculture sector accounts for about 20  per cent of GDP1.
    •    80  per cent of total employment and higher in rural areas.
    •    55  per cent of household incomes (national average) adding self-consumption and income from selling agricultural products2.
    •    40  per cent of export earnings (2003).
    •    The economy is not diversified and the average level of education is low, with few options for finding non-farm employment and incomes in rural zones.

1. Introduction

Jordan is an Arab country located in the heart of the Middle East. It is a highly centralized country in both political and economic terms, with a constitutional monarchy. The parliament consists of an upper-house appointed by the king and an elected lower-house. The king appoints the prime minister, who in turn, appoints a cabinet of ministers.

1.1. General Information

The country shares borders with Iraq to the east, Israel and the Palestinian Authority to the west, Syria to the north and Saudi Arabia to the south. In 2005, the population of Jordan was estimated at 5.5 million people with a population growth rate around 2.3 per cent, living in an area of about 89,300 sq. km. Most of the population is urbanized (82 per cent), with more than half living in the capital, Amman, and in the Zarqa governorate. About 60 per cent of the total population is under 25 and 38 per cent is under the age of 15 (United Nations, 2006). Jordan is classified as a lower-middle income country, with an economy that is severely affected by water scarcity and limited land resources. The capital Amman dominates over  80  per cent of the country’s economy.

1.1. Geography

Japan is a crescent-shaped archipelago consisting of four main islands named Hokkaido, Honshu, Shikoku, and Kyushu, and of a few thousand small islands, with a total area of 3,77,907 square kilometers. The country is mountainous, with forests accounting for 66 per cent of the total area, and arable land 13 per cent.

1.2. Climate

The archipelago is almost 3,000 km in length and stretches from north to south, and  includes subartic, temperate and subtropical zones.

In winter, the side of the country facing the Sea of Japan, include Niigata and Fukui, is known worldwide for its heavy snowfall, but the side facing the Pacific Ocean has little or no snowfall. From spring to fall, there is no big difference between these areas. The summer season starts with an almost one month long baiu (rainy season) around June. After the baiu, the temperature rises to more than 30 degree Celsius, and it become very humid. In the fall, a few typhoons hit Japan, occasionally causing a major disaster.

1. Introduction

Iran, with an area of 1648 thousand sq.kms.,  is situated in the eastern portion of the northern hemisphere, in the south west of Asia, and is considered as one of the Middle East countries. Iran is a mountainous country with a variety of climates. The average temperature and rainfall for the whole country are quoted as 18ºC and 240 mm respectively (CAPES, 1996). The country is also organized into 28 provinces. Over the past two decades, rapid rate of population growth has been a major source of concern in Islamic Republic of Iran. The population of the country passed the 60 million figures in 1993 and is projected to reach 86 million by the year 2010. In fact, the Iranian population has doubled in this period (CAPES, 1996). For example, according to the 1991 census, the female population of 15 years and above was 15 million (Anonymous, 1998). However, thanks to considerable investments and well-organized and directed national population planning program, population growth rate is now 1.5 percent in the urban and two percent in the rural areas. At the national level, the figure is 1.65 percent (CAPES, 1996).

1. Country Background

India is one of the oldest civilisations in the world with rich cultural heritage. India has become self-sufficient in agricultural production, and is now the tenth industrialised country in the world. It covers an area of 32,87,263 sq km. Lying entirely in the northern hemisphere, the mainland extends between latitudes 8°4' and 37°6' north, longitudes 68°7' and 97°25' east, and measures about 3,214 km from north to south between the extreme latitudes and about 2,933 km from east to west between the extreme longitudes. 
Agriculture is the mainstay of the Indian economy, as it constitutes the backbone of the rural livelihood security system. It is the core of planned economic development in India, as the trickle-down effect of agriculture is significant in reducing poverty and regional inequality in the country. Growth in agriculture has a maximum cascading impact on other sectors, leading to the spread of benefits over the entire economy and the largest segment of population. 141 million hectares is the net sown area, while 190 million hectares is the gross cropped area. The net irrigated area is 57 million hectares with a cropping intensity of 134 per cent. Eighty-two per cent of farmers have small and marginal land holdings.

It covers an area of 112.622 km².

With the third General Census of the Population and Habitat in February 2002, Benin counted 6,769,914 inhabitants thereby giving an average density of 60.11 inhabitants per km². Currently the population is estimated to nearly 8 million inhabitants with a natural rate of increase of 2.8 per cent. The average densities estimated from the last census of the population vary between 16 inhabitants per km² in the department of Borgou and 322 inhabitants per km² in the department of Atlantic.

1. Introduction

Afghanistan imperiled by decades of war, is  now a country on the rebound. With the days of relative peace up on the Afghan people, resources are being gathered and projects put onto place, in an effort to revitalize the previously stagnant economy. The rehabilitation of the agricultural economy in Afghanistan depends to a large extent on whether Afghanistan’s Agricultural Sector will be able to recover from the effects of war, serious consecutive droughts and a multitude of endemic crop/ livestock diseases. Afghanistan is a pastoral country with more than 85 per cent of the land area incapable of growing even a narrow range of crops, thus being largely rangeland.  Agriculture produces food, provides food security, enhances crop production, generates cash incomes for rural and urban populations, provides fuel and transport, and produces value added goods which can have multiplier effects and creates a need for services.  Furthermore, agricultural diversity production and income provide year-round employment, and spread risk. Livestock also form a major capital reserve of farming households.
