The right to a clean, healthy and sustainable environment is thus well recognized at the global, regional and national levels. However, despite this recognition, several challenges hinder attainment of this right. Some of these challenges are discussed below.
Climate Change
Climate change has been defined as change of climate which is attributed directly or indirectly to human activities which alter the composition of the global atmosphere and which are in addition to natural climate variability observed over comparable time periods. Climate change has become a global concern in the 21st century and has been a dominant subject in political, economic, legal, social, environmental and scientific discussions. It is majorly caused by human activities that lead to atmospheric concentration of green-house gases such as burning of fossil fuels, deforestation and increase in carbon dioxide levels.
Kenya like the rest of the world is faced with the threat of climate change. It has been observed that countries such as Kenya which have contributed the least to climate change are the ones that are the most affected by its impacts. Climate change hinders the realization of the right to a clean, healthy and sustainable environment since it results food insecurity, water scarcity, depletion of natural resources, displacement of people and health hazards among other concerns.
Owing to the threat of climate change, the global community has come together under the Paris Agreement which is aimed at combating climate change and adapting to its effects by holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels. There is need to promote effective climate change mitigation and adaptation in order to realize the right to a clean, healthy and sustainable environment.
Unsustainable Management and Use of Natural Resources
Natural resources such as water, soil, air and forests are essential for survival and livelihood since they provide ingredients that support life. However, increase in human population has resulted in pressure on natural resources, sometimes resulting in their degradation and depletion. This is due to the fact that increase in human population puts pressure on natural resources such as food, water and energy sometimes resulting in their unsustainable use.
Poor use of natural resources is a global challenge that poses a threat to sustainability of natural resources and results in serious environmental threats such deforestation and forest degradation, biodiversity loss, ecosystem degradation, reduction in soil quality and fall in available water quantity. This challenge is coupled with poor natural resources management laws, policies and practices in some countries which hinder effective management and use of these resources.
Unsustainable management and use of natural resources hinders realization of the right to a clean, healthy and sustainable environment since it affects the Sustainable Development agenda. The 2030 Agenda on Sustainable Development recognizes this challenges and seeks to promote responsible consumption and production through efficient management of natural resources. There is need to enhance sustainable management and use of natural resources in order to achieve the right to a clean, healthy and sustainable environment.
Pollution
Pollution has been defined as any direct or indirect alteration of the physical, thermal, chemical, biological, or radio-active properties of any part of the environment by discharging, emitting, or depositing wastes so as to affect any beneficial use adversely, to cause a condition which is hazardous or potentially hazardous to public health, safety or welfare, or to animals, birds, wildlife, fish or aquatic life, or to plants.
Environmental pollution has also been defined as the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected. Pollution occurs in various forms including air, water and soil.
Pollution has been attributed to many factors which include waste by-products emanating from industrialization of our society, the introduction of motorized vehicles, and the explosion of the human population, leading to an exponential growth in the production of goods and services. Cases of air, water and soil pollution have been widely reported in Kenya.
There have been reports of discharge of untreated industrial waste into the atmosphere polluting soil and water resources. Further, there have been reports indicating that raw water in Kenya is too polluted with chemicals and heavy metals to be fit for irrigation or human and livestock consumption. However, pollution is not a novel problem to Kenya since it’s a global concern that affects virtually all nations and threatens environmental sustainability.
Human activities through urbanization, industrialization, mining, and exploration are at the forefront of global environmental pollution. Environmental pollution is a threat to not only the sustainable development agenda but also to the very existence of the humankind. It compromises the quality of air, water and soil and could result in concerns such as health hazards and diseases thus hindering the realization of the right to a clean, healthy and sustainable environment. There is need to promote effective pollution control in order to achieve a clean, healthy and sustainable environment.
Poverty
Poverty can hinder realization of procedural aspects of the right to a clean, healthy and sustainable environment such as access to information, public participation, and access to justice or effective remedies. It can also hinder access to substantive aspects of the right such as access to food and clean water and sanitation.
Poverty can also result in overexploitation of natural resources such as forests, water resources and energy sources which could potentially result in their depletion or degradation. This concern has been recognize at the global level by the 2030 Agenda on Sustainable Development which acknowledges that eradicating poverty in all its forms remains one of the greatest challenges facing humanity. There is need to combat poverty in order to actualize the right to a clean, healthy and sustainable environment.
