Environmental issues in Yemen are abundant and are divided into the categories of land and water. In the aspect of water, Yemen has limited natural fresh water resources and inadequate supplies of potable water. As for the land, two main issues of Yemen are overgrazing and desertification. Yemen has signed several international agreements: Climate Change-Kyoto Protocol, Desertification, Endangered Species, Environmental Modification, Hazardous Wastes, Law of the Sea, and Ozone Layer Protection.

Yemen maintains diverse landscapes of mountains, plains, and deserts. There is narrow coastal plain backed by flat-topped hills and rugged mountains; and dissected upland desert plains in center slope into the desert interior of the Arabian Peninsula. [1]
Forests covering the highlands are eliminated due to increasingly overgrazing and logging. Yemen covers 203,849 square miles (527,970 square kilometers) including 112 islands and 0 square kilometers of open water. The climate of Yemen is mostly desert weather. It is hot and humid along the coastal sections. Hot, dry and harsh desert in the east. Climate in the western mountains is affected by seasonal monsoons. Average Daily Temperatures in January: 13.9 °C/57 °F; in July: 21.7 °C/71 °F. Average annual rainfall in Yemen is 508mm/20". [2]

Water issues

Water issues in Yemen are based on two aspects, water shortage and water quality.

Water shortage

Yemen has suffered from chronic water shortages owing to its climate, years of water mismanagement, and population growth. The capital Sana’a is at risk of running out of water as soon as 2017 while an estimated 84% of the population in the southern governorate of Al Dhale’e struggle daily to find or buy enough clean water to drink, cook, and grow food. [3]

Each Yemeni only has access to about 140cu.m. of water per year for all uses on average. Excluding its coastal waters, Yemen has no permanent body of open water. [4]

The vast majority of the water in Yemen, as much as 90 percent, goes to small-scale farming, at a time when agriculture contributes only 6 percent of GDP. [5] The introduction of deep tube wells led to a drastic expansion of land under cultivation. In the period from 1970 to 2004, the irrigated area increased tenfold, from 37,000 to 407,000 hectares, 40 percent of which was supplied by deep groundwater aquifers. [2]
Farmers began growing less of the local, drought-resistant varieties of wheat and more water-intensive cash crops such as citrus and bananas. [6]

Water quality

Degraded water supply infrastructure is a significant factor in Yemen's current water scarcity. Community water sources were overburdened or dysfunctional before the crisis, and have endured conflict-related damage and further strain due to the influx of IDPs. [3]
Bacterial diarrhea, hepatitis A and typhoid fever are leading illnesses in Yemen. More than 30,000 Yemenis, suffer from acute watery diarrhea in 2011 alone. Lack of access to improved water supply is responsible for the spread of water-borne diseases. [7] Study of surface water and ground water in Yemen shows that the upstream site of surface water contains high concentration physico-chemical parameters. Leachate composition at Ibb landfill is very dangerous for polluting the groundwater, surface water and soil. All tested parameters except Ni and Cr in Ibb landfill leachate exceed the permissible limit required for treated wastewater discharge determined by Yemen's Ministry of Water and Environment (1999). [8]

Reform

The reform program in Yemen is on track and is beginning to take effect. Reforms in urban water and sanitation started more than a decade ago. Network coverage has expanded rapidly, and service standards have improved whilst costs for most connected consumers remain highly affordable. In 1997, Cabinet Resolution 237 was issued which embraced a policy of decentralization, corporatization, commercialization, separation of service delivery and regulatory function. Established partnership with the private sector increases efficiency, improves service delivery and ultimately reduces the cost burden on government. These reforms have been incorporated into the national water strategy (NWSSIP, 2004) and into the update of the strategy currently being prepared. [9]

Desertification

There are about 6,800 square kilometers of irrigated land in Yemen (2008). Overgrazing of pastureland is endemic. Soil erosion and desertification are also hazards in Yemen. [2] Agricultural lands in Yemen are subject to various degrees of degradation and decline of soil productivity. Desertification largely threatens the natural resource-base. [10]
Desertification is best expressed by the loss of land productivity, following mining of a resource. Monoculture in the absence of any farm inputs or rotations and erroneous farming practices constitute common features of Yemeni agriculture, which contribute greatly to the decline of agricultural yields and ultimately to desertification through loss of the resource productivity potential. Any reduction of the agricultural sector's importance in the national economy, will result in reduction of the national income and eventually affect the pace of development of the country. Main physical aspects of desertification are reduction in woodland, mangrove biomass and in species diversity, and depletion in groundwater. [10]
A number of planning frameworks related to rural development and natural resource conservation were developed. United Nations Convention to Combat Desertification (UNCCD) is determined to implement the convention's main objectives of combating desertification and mitigating the effects of drought in order to achieve sustainable development. The United Nations Conference on Environment and Development (UNCED) has created many tools for the management, conservation, and sustainable development of natural resources. [10]

Air Pollution

As of 2017, Yemen was one of only 3 countries in the world with widespread use of leaded engine gasoline for automobiles, the others being Algeria and Iraq. [11] Concerns over the toxicity of lead [12] led to a ban on leaded automobile gasoline in most countries prior to 2011. [13]

Sustainable development

The Yemeni Government is facing challenging difficulties in many directions including severe water shortage, declining oil reserves, and succession questions. [14] National Assessment of Sustainable Development in Yemen aims to highlight the integration of the social dimension and environmental interest in development planning, illustrating the Millennium Development Goals (MDGs) and setting the sustainable development priorities beyond 2015. Sustainable development is achieved on the basis of three fundamental pillars: economic growth, social development, and rationalization use of natural resources. [14] The MDGs established measurable and universally-agreed objectives for eradicating extreme poverty and hunger, preventing deadly but treatable disease, and expanding educational opportunities to all children. The MDGs drove progress in several important areas: income poverty, access to improved sources of water, primary school enrollment and child mortality. [15]
During many decades and via the support of international approaches, consecutive Yemeni governments adopted a number of initiatives and put great efforts. The following are most important ones: [16]

<span class="mw-page-title-main">Water scarcity</span> Lack of fresh water resources to meet water demand

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two types of water scarcity: physical or economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands, including that needed for ecosystems to function effectively. Arid areas for example Central and West Asia, and North Africa often suffer from physical water scarcity. On the other hand, economic water scarcity is caused by a lack of investment in infrastructure or technology to draw water from rivers, aquifers, or other water sources, or insufficient human capacity to satisfy the demand for water. Much of Sub-Saharan Africa has economic water scarcity.

Water supply and sanitation in Yemen is characterized by many challenges as well as some achievements. A key challenge is severe water scarcity, especially in the Highlands, prompting The Times of London to write "Yemen could become the first nation to run out of water". A second key challenge is a high level of poverty, making it very difficult to recover the costs of service provision. Access to water supply sanitation in Yemen is as low or even lower than that in many sub-Saharan African countries. Yemen is both the poorest country and the most water-scarce country in the Arab world. Third, the capacity of sector institutions to plan, build, operate and maintain infrastructure remains limited. Last but not least the security situation makes it even more difficult to improve or even maintain existing levels of service.

Drinking water supply and sanitation in Benin has been subject to considerable progress since the 1990s, in particular in rural areas, where coverage is higher than in many other African countries, and almost all development partners follow a national demand-responsive strategy, which has been adopted in 1992. New strategies to increase water supply in rural and urban areas have been adopted in 2005 and 2006. Tariffs in urban and rural areas are usually high enough to cover the costs for operation and maintenance.

<span class="mw-page-title-main">Water security</span> Too much water can also drive water insecurity

Water security is the basic goal of water policy and water management. A society with a high level of water security makes the most of water's benefits for humans and ecosystems and limits the risk of destructive impacts associated with water. These include too much water (flood), too little water or poor quality (polluted) water. A widely accepted definition of water security is: "Water security is the reliable availability of an acceptable quantity and quality of water for health, livelihoods and production, coupled with an acceptable level of water-related risks". Water security is framed as a situation where water-related risks are managed and water-related opportunities are captured but it is difficult to provide a set of indicators to quantify this.

Soil governance refers to the policies, strategies, and the processes of decision-making employed by nation states and local governments regarding the use of soil. Globally, governance of the soil has been limited to an agricultural perspective due to increased food insecurity from the most populated regions on earth. The Global Soil Partnership, GSP, was initiated by the Food and Agriculture Organization (FAO) and its members with the hope to improve governance of the limited soil resources of the planet in order to guarantee healthy and productive soils for a food-secure world, as well as support other essential ecosystem services.

The water, energy and food security nexus according to the Food And Agriculture Organisation of the United Nations (FAO), means that water security, energy security and food security are very much linked to one another, meaning that the actions in any one particular area often can have effects in one or both of the other areas.

Tanzania has a current population of 55.57 million people. Current statistics form the World Bank show that in 2011, 49.1% of Tanzanians lived below US$1.90 per day. This figure is an improvement over 2007's report indicating a poverty rate of 55.1%. Tanzania has seen annual GDP gains of 7% since 2010 and this economic growth is attributed to this positive trends for poverty alleviation in Tanzania. The 2019 World Bank report showed that in the last 10 years, poverty has reduced by 8 percent, from 34.4% in 2007 to 26.4% in 2018.

The Sustainable Development Goals (SDGs) or Global Goals are a collection of 17 interlinked global goals designed to be a "shared blueprint for peace and prosperity for people and the planet, now and into the future". The SDGs were set up in 2015 by the United Nations General Assembly (UN-GA) and are intended to be achieved by 2030. They are included in a UN-GA Resolution called the 2030 Agenda or what is colloquially known as Agenda 2030. The SDGs were developed in the Post-2015 Development Agenda as the future global development framework to succeed the Millennium Development Goals which were ended in 2015. The SDGs emphasize the interconnected environmental, social and economic aspects of sustainable development, by putting sustainability at their center.

The Growth and Transformation Plan (GTP) was a national five-year plan created by the Ethiopian government to improve the country's economy by achieving a projected gross domestic product (GDP) growth of 11-15% per year from 2010 to 2015. The plan included details of the cost and specific targets the government expects to hit by pursuing the following objectives.

Extreme poverty is defined as living on less than US$2.50 purchasing power parity. Uganda has made significant progress in eradicating poverty and achieved the first millennium development goal of halving the number of people in extreme poverty. Uganda was listed as the 9th most successful country in Africa as regards poverty eradication. The percentage of Ugandans living in absolute poverty has been on a substantial decline, and the finance ministry in the country projected that the extreme poverty level will be reduced to 10% in the future. This success has been attributed to the deliberate efforts to combat poverty in the country by numerous national strategies that are explained below.

Water in Africa is an important issue encompassing the sources, distribution and economic uses of the water resources on the continent. Overall, Africa has about 9% of the world's fresh water resources and 16% of the world's population. Among its rivers are the Congo, Nile, Zambezi, Niger and Lake Victoria, considered the world’s second largest lake. Yet the continent is the second driest in the world, with millions of Africans still suffering from water shortages throughout the year.
